+
+## Chiron (Assistant)
+
+Personal AI assistant (Plan Mode). Read-only analysis, planning, and guidance
+
+## Available Specialists
+
+- **Apollo (Knowledge Management)**: Private knowledge specialist. Manages Obsidian vault, personal notes, and private knowledge graph
+- **Athena (Researcher)**: Work knowledge specialist. Manages Outline wiki, documentation, and knowledge organization
+- **Calliope (Writer)**: Writing specialist. Creates documentation, reports, meeting notes, and prose
+- **Hermes (Communication)**: Work communication specialist. Handles Basecamp tasks, Outlook email, and MS Teams meetings
+
+=== SYSTEM.md (first 20 lines) ===
+You are Chiron, the wise centaur from Greek mythology, serving as the main orchestrator in plan and analysis mode. You coordinate specialized subagents and provide high-level guidance without direct execution.
+
+**Your Core Responsibilities:**
+1. Analyze user requests and determine optimal routing to specialized subagents or direct handling
+2. Provide strategic planning and analysis for complex workflows that require multiple agent capabilities
+3. Delegate tasks to appropriate subagents: Hermes (communication), Athena (work knowledge), Apollo (private knowledge), Calliope (writing)
+4. Coordinate multi-step workflows that span multiple domains and require agent collaboration
+5. Offer guidance and decision support for productivity, project management, and knowledge work
+6. Bridge personal and work contexts while maintaining appropriate boundaries between domains
+
+**Process:**
+1. **Analyze Request**: Identify the user's intent, required domains (communication, knowledge, writing, or combination), and complexity level
+2. **Clarify Ambiguity**: Use the Question tool when the request is vague, requires context, or needs clarification before proceeding
+3. **Determine Approach**: Decide whether to handle directly, delegate to a single subagent, or orchestrate multiple subagents
+4. **Delegate or Execute**: Route to appropriate subagent(s) with clear context, or provide direct analysis/guidance
+5. **Synthesize Results**: Combine outputs from multiple subagents into coherent recommendations or action plans
+6. **Provide Guidance**: Offer strategic insights, priorities, and next steps based on the analysis
+
+**Delegation Logic:**
+- **Hermes**: Work communication tasks (email drafts, message management, meeting coordination)

+# Task 4: OpenCode File-Based Agent Format Research
+
+**Date**: 2026-04-10  
+**Status**: ✅ Complete  
+**Research Method**: WebFetch + Documentation Analysis
+
+---
+
+## Executive Summary
+
+OpenCode supports **two agent configuration methods**:
+1. **JSON** - Embedded in `opencode.json` (config.json)
+2. **Markdown Files** - File-based in `.opencode/agents/` directory (per-project) or `~/.config/opencode/agents/` (global)
+
+This research focuses on the **file-based markdown format**, which is the target for the harness-agnostic migration.
+
+---
+
+## File Location & Discovery
+
+### Directory Structure
+
+**Per-project agents** (takes precedence):
+```
+.opencode/agents/
+├── agent-name.md
+├── another-agent.md
+└── ...
+```
+
+**Global agents** (fallback):
+```
+~/.config/opencode/agents/
+├── agent-name.md
+├── another-agent.md
+└── ...
+```
+
+### Discovery Mechanism
+
+- OpenCode **scans both directories** for `*.md` files
+- The **filename (without .md extension)** becomes the **agent name**
+- Per-project agents **override** global agents with the same name
+- All agents are loaded at startup and available via `Tab` switching or `@mention`
+
+### Key Finding
+
+**The agent name is derived from the filename**, not from a `name` field in the frontmatter. Example:
+- File: `review.md` → Agent name: `review`
+- File: `code-reviewer.md` → Agent name: `code-reviewer`
+
+---
+
+## YAML Frontmatter Specification
+
+All file-based agent markdown files must include YAML frontmatter with the following fields:
+
+### Required Fields
+
+| Field | Type | Description | Example |
+|-------|------|-------------|---------|
+| `description` | string | Brief description of agent purpose and when to use it. **REQUIRED**. | `"Reviews code for quality and best practices"` |
+
+### Optional Fields
+
+| Field | Type | Default | Description |
+|-------|------|---------|-------------|
+| `mode` | string | `all` | Agent mode: `primary`, `subagent`, or `all` |
+| `model` | string | Model globally configured in config | Override LLM model for this agent |
+| `temperature` | float | Model-specific (usually 0 or 0.55 for Qwen) | LLM response randomness (0.0–1.0) |
+| `top_p` | float | — | Alternative to temperature for diversity control |
+| `steps` | integer | No limit | Max agentic iterations before forced text-only response |
+| `disable` | boolean | `false` | Set to `true` to disable the agent |
+| `hidden` | boolean | `false` | Hide from `@` autocomplete (subagents only) |
+| `color` | string | — | Hex color (e.g., `#FF5733`) or theme color (primary, secondary, accent, success, warning, error, info) |
+| `permission` | object | — | Permission rules for edit, bash, webfetch, question, websearch, external_directory |
+| `task` | object | — | Control which subagents this agent can invoke via Task tool |
+
+### Provider-Specific Fields
+
+Any additional fields are **passed through directly to the LLM provider**. Example for OpenAI reasoning models:
+```yaml
+---
+description: Agent using high reasoning effort
+model: openai/gpt-5
+reasoningEffort: high
+textVerbosity: low
+---
+```
+
+---
+
+## Permission Format (YAML)
+
+Permissions control what actions an agent can perform. The format supports two styles:
+
+### Simple Format (Single Action)
+
+```yaml
+permission:
+  edit: deny
+  bash: ask
+  webfetch: allow
+```
+
+### Granular Format (Rules Array)
+
+For more control over specific patterns:
+
+```yaml
+permission:
+  edit: 
+    "*": allow
+    "/run/agenix/**": deny
+  bash:
+    "*": ask
+    "git status*": allow
+    "git log*": allow
+    "git push": ask
+    "grep *": allow
+  webfetch: deny
+  question: allow
+  websearch: allow
+  external_directory:
+    "*": ask
+    "~/p/**": allow
+    "~/.config/opencode/**": allow
+    "/tmp/**": allow
+```
+
+### Permission Actions
+
+| Value | Meaning |
+|-------|---------|
+| `allow` | Tool allowed without approval |
+| `ask` | Prompt user for approval before running |
+| `deny` | Tool disabled |
+
+### Supported Permission Keys
+
+| Key | Values | Notes |
+|-----|--------|-------|
+| `edit` | `allow\|ask\|deny` or nested rules | File write/patch operations |
+| `bash` | `allow\|ask\|deny` or nested rules | Bash command execution; supports glob patterns |
+| `webfetch` | `allow\|ask\|deny` | HTTP requests |
+| `question` | `allow\|ask\|deny` | User questions/clarification |
+| `websearch` | `allow\|ask\|deny` | Web search operations |
+| `external_directory` | `allow\|ask\|deny` or nested rules | Access to external directories |
+| `task` | nested rules | Subagent invocation control (glob patterns) |
+
+### Glob Pattern Support
+
+Patterns support wildcards and recursion:
+- `*` — single-level wildcard
+- `**` — recursive wildcard
+- `git push*` — suffix matching
+- `~/p/**` — home directory paths
+- `/run/agenix/**` — absolute paths
+
+### Rule Precedence
+
+When multiple rules match, the **last matching rule wins**:
+
+```yaml
+bash:
+  "*": ask
+  "git status*": allow
+  "git push*": deny
+```
+
+In this example:
+- `git status` matches both `*` and `git status*` → result: **allow** (last rule wins)
+- `git push origin main` matches both `*` and `git push*` → result: **deny**
+- `ls -la` matches only `*` → result: **ask**
+
+---
+
+## Mode Field Values
+
+| Mode | Type | Description |
+|------|------|-------------|
+| `primary` | Primary agent | Agent available via `Tab` key switching; handles main conversation |
+| `subagent` | Specialized agent | Invoked via `@mention` or automatically by other agents for specific tasks |
+| `all` | Flexible | Can be used as both primary and subagent (default if omitted) |
+
+---
+
+## System Prompt Delivery
+
+The markdown file body (after the YAML frontmatter) contains the **system prompt**:
+
+```markdown
+---
+description: Code review without edits
+mode: subagent
+permission:
+  edit: deny
+---
+You are a code reviewer. Focus on:
+- Code quality and best practices
+- Potential bugs and edge cases
+- Performance implications
+- Security considerations
+
+Provide constructive feedback without making direct changes.
+```
+
+The **markdown content is passed directly as the system prompt** to the LLM. It supports:
+- Inline markdown formatting
+- Lists and sections
+- Structured instructions
+- Code examples (fenced with backticks)
+
+---
+
+## Default Behavior for Omitted Fields
+
+| Field | Default | Notes |
+|-------|---------|-------|
+| `description` | **ERROR** | Required; absence causes parse failure |
+| `mode` | `all` | Agent can be used as primary or subagent |
+| `model` | Global config model | Primary agents use global model; subagents use parent's model |
+| `temperature` | Model-specific | Usually 0 for most models; 0.55 for Qwen models |
+| `permission` | Full access | If omitted, all tools enabled (no restrictions) |
+| `disable` | `false` | Agent is enabled by default |
+| `hidden` | `false` | Agent visible in `@` autocomplete (if subagent) |
+
+---
+
+## Interaction with config.json (JSON Format)
+
+### Current State (Task 1 Finding)
+
+The current system embeds agents in **config.json** via JSON:
+
+```json
+{
+  "agent": {
+    "build": {
+      "description": "...",
+      "mode": "primary",
+      "permission": { ... }
+    }
+  }
+}
+```
+
+### File-Based Agents Complement, Don't Replace
+
+- **JSON agents** (in config.json) are loaded from embedded config
+- **Markdown agents** (.opencode/agents/*.md files) are symlinked
+- **Both are loaded** and available simultaneously
+- **Markdown agents override** JSON agents with the same name
+
+### Migration Path
+
+The harness-agnostic migration will:
+1. Move agent definitions from `agents.json` → `.opencode/agent/{name}.md` files
+2. Update home-manager deployment to symlink `.opencode/agents/` instead of embedding `agents.json`
+3. System prompt changes (markdown file edits) will **NOT require `home-manager switch`**
+
+---
+
+## Key Advantage: Prompt Changes Don't Require home-manager switch
+
+### Current Limitation (JSON/Embedded)
+
+```
+agents.json → home-manager → embedded into config.json
+↓
+Change required in nixpkgs module
+↓
+home-manager switch (full system rebuild)
+```
+
+### New Capability (File-Based)
+
+```
+.opencode/agents/{name}.md → home-manager → symlinks to ~/.config/opencode/agents/
+↓
+Change markdown file directly
+↓
+OpenCode reloads on next startup (NO home-manager switch needed)
+```
+
+**This is the KEY ADVANTAGE** of file-based agents: faster iteration on prompts and agent configuration.
+
+---
+
+## Limitations & Gotchas
+
+### No Name Field in Frontmatter
+
+- Agent name comes from **filename only**
+- No `name: foo` field in frontmatter
+- Renaming file renames the agent
+
+### Model References with {file:...}
+
+In JSON config, you can reference external files:
+```json
+{
+  "prompt": "{file:./prompts/build.txt}"
+}
+```
+
+In markdown files, the **body IS the prompt** — no `{file:...}` syntax. The entire markdown content after frontmatter is the system prompt.
+
+### Subdirectories Not Scanned
+
+- Only files directly in `.opencode/agents/` are loaded
+- Subdirectories are ignored
+- All agent definitions must be in one directory level
+
+### Filename Validation
+
+The filename should follow these conventions (not enforced, but recommended):
+- Lowercase letters, numbers, hyphens: `[a-z0-9-]+`
+- No spaces, no special characters
+- Examples: `code-reviewer.md`, `security-auditor.md`, `docs-writer.md`

+You are an expert code reviewer with deep knowledge of software architecture, security best practices, and performance optimization.
+
+## Your Mission
+
+Review code for:
+1. **Correctness** - Logic errors, edge cases, off-by-one bugs
+2. **Security** - Input validation, injection vulnerabilities, data exposure
+3. **Performance** - Algorithmic efficiency, memory usage, unnecessary allocations
+4. **Maintainability** - Code clarity, naming, documentation, SOLID principles
+5. **Testing** - Coverage gaps, missing test cases, integration test concerns
+
+## Process
+
+1. Ask clarifying questions about context and constraints
+2. Provide specific, actionable feedback with examples
+3. Suggest refactorings with rationale
+4. Never make changes directly (read-only mode)
+5. Prioritize critical issues over style concerns
+
+## Output Format
+
+- **Critical Issues** (must fix before merge)
+- **Important Improvements** (should fix)
+- **Nice-to-Have Suggestions** (consider for future)
+- **Questions** (for author clarification)
+```

+
+---
+
+## Questions Addressed
+
+### Q: Do file-based agents need `home-manager switch` for prompt changes?
+
+**A: NO** ✅
+
+- File changes are immediately available
+- `.opencode/agents/` is symlinked (not embedded)
+- OpenCode reloads agent definitions at startup
+- Prompt changes require only file edit + app restart
+
+**This is the KEY ADVANTAGE** driving the migration.
+
+### Q: What directory: `agent` or `agents`?
+
+**A: `agents` (plural)** (both global and per-project)
+- Global: `~/.config/opencode/agents/`
+- Per-project: `.opencode/agents/`
+
+### Q: Do agent names need a `name` field in frontmatter?
+
+**A: NO** 
+
+- Agent name comes from **filename only**
+- No `name: foo` field in frontmatter
+- Example: `review.md` → agent name is `review`
+
+### Q: What YAML frontmatter fields are required?
+
+**A: Only `description`** is truly required
+
+- All other fields have sensible defaults
+- Missing fields use their defaults
+- Frontmatter-less file will fail to parse
+
+### Q: How are permissions specified in markdown?
+
+**A: Same nested object format as JSON**
+
+```yaml
+permission:
+  edit: 
+    "*": allow
+    "/sensitive/**": deny
+  bash:
+    "*": ask
+    "git push": deny
+```
+
+---
+
+## Confirmation Summary
+
+| Question | Finding |
+|----------|---------|
+| **Directory**: `agent` or `agents`? | `agents/` (both global and per-project) |
+| **File naming**: How determined? | Filename (without .md) becomes agent name |
+| **Required fields**: What's mandatory? | `description` only; others have defaults |
+| **Permission format**: YAML or different? | Same nested object format as JSON |
+| **Mode values**: Options? | `primary` \| `subagent` \| `all` |
+| **Prompt format**: How specified? | Markdown body after frontmatter |
+| **Requires HM switch for prompt changes?** | **NO** ✅ (major advantage) |
+| **Does frontmatter need `name` field?** | **NO** (filename is the name) |
+| **Can agents be in subdirectories?** | **NO** (only root level of `.opencode/agents/`) |
+| **Can you override agents from JSON config?** | **YES** (markdown agents override JSON with same name) |
+
+---
+
+## Next Steps (Task 9: OpenCode Renderer)
+
+The renderer will generate `.opencode/agents/{name}.md` files with:
+
+1. **Frontmatter generation**:
+   - Convert agent.toml `[description]` → YAML `description:`
+   - Convert `[mode]` → YAML `mode:`
+   - Convert `[temperature]` → YAML `temperature:`
+   - Convert `[permission]` from two-level format → nested YAML objects
+
+2. **Body generation**:
+   - Use agent.toml `system_prompt` field → markdown body
+
+3. **File naming**:
+   - Filename: `{agent_name}.md` (from agent.toml `name` field)
+   - Agent name in OpenCode: derived from filename automatically

+- These were NOT in scope and MUST NOT be touched per the plan
+- Skills were restored via: `git checkout HEAD -- skills/`
+- ROOT CAUSE: Subagents may try to "clean up" untracked/modified files when working in the repo

+
+## [2026-04-10] NOTE: nix eval requires --impure for builtins.readFile with absolute paths
+- Task 2 spike required `nix eval --impure --expr 'builtins.fromTOML (builtins.readFile <path>)'`
+- This is expected for absolute filesystem paths outside the flake
+- For flake-based rendering (nixpkgs lib), this is not an issue as files go through `pkgs.writeText` or are read at flake evaluation time via `inputs`

+- Plan: harness-agnostic-migration (21 tasks + 4 final)
+- AGENTS repo: /home/m3tam3re/p/AI/AGENTS
+- nixpkgs repo: /home/m3tam3re/p/NIX/nixpkgs
+- TOML chosen as canonical format (builtins.fromTOML, no IFD)
+- Renderers belong in nixpkgs, not AGENTS repo
+- 6 agents: chiron, chiron-forge, hermes, athena, apollo, calliope
+- OpenCode: file-based agents (.opencode/agent/*.md) NOT config.json embedding
+- Pi: no subagents — renders AGENTS.md + SYSTEM.md only
+- Claude Code: name must be [a-z0-9-]+ (slugified)
+- No model in agent.toml (per-machine via home-manager)
+- No MCP in agent.toml (tool-specific infrastructure)

+## [2026-04-10] Task 1: Capture Golden File Baseline
+
+### Golden File Created
+- **Path**: `.sisyphus/evidence/agents-golden.json`
+- **Method**: `jq --sort-keys . agents/agents.json`
+- **Status**: ✓ Valid JSON, parseable, verified
+
+### Agent Count
+- **Total**: 6 agents
+- **Verification**: `jq 'keys | length'` → 6 ✓
+
+### Agent Names (Alphabetically Sorted)
+1. Apollo (Knowledge Management) — subagent, private knowledge specialist
+2. Athena (Researcher) — subagent, work knowledge specialist
+3. Calliope (Writer) — subagent, writing specialist
+4. Chiron (Assistant) — primary agent, plan mode
+5. Chiron Forge (Builder) — primary agent, build mode
+6. Hermes (Communication) — subagent, communication specialist
+
+### Agent Object Structure
+Every agent has 5 top-level keys:
+- `description` (string) — agent purpose and capabilities
+- `mode` (string) — "primary" or "subagent"
+- `model` (string) — LLM model ID (all use "zai-coding-plan/glm-5")
+- `prompt` (string) — reference to prompt file via `{file:./prompts/...}`
+- `permission` (object) — capability matrix with granular controls
+
+### Permission Structure
+All agents have 6 permission categories:
+- `question` → "allow" | "deny" | "ask"
+- `webfetch` → "allow" | "deny" | "ask"
+- `websearch` → "allow" | "deny" | "ask" (not all agents)
+- `edit` → nested rules (allow/deny per path pattern)
+- `bash` → nested rules (allow/deny per command pattern)
+- `external_directory` → nested rules (allow/deny per path pattern)
+
+### Baseline Purpose
+This golden file serves as the **canonical reference** for backward-compat verification in Task 8.
+It will be compared against output from the harness-agnostic bridge to ensure config integrity.
+
+### Next Steps
+- Task 8 will generate a comparable JSON from the bridge
+- Diff will be computed: `jq --sort-keys . bridge_output.json > bridge-output.json && diff agents-golden.json bridge-output.json`
+- Any structural or content changes will be flagged
+
+## [2026-04-10] Task 2: TOML Feasibility Spike
+
+**Result: ✅ PASS**
+
+### Test Execution
+- Full Chiron-Forge TOML (16 lines, 5 permission sections, 15 bash rules, 4 external_directory rules): **PARSED SUCCESSFULLY**
+- Minimal TOML (2 lines, name + description only): **PARSED SUCCESSFULLY**
+- Parser: `nix eval --impure --expr 'builtins.fromTOML (builtins.readFile <path>)' --json`
+
+### Glob Patterns Verified
+All complex patterns preserved exactly:
+- `rm -rf *` → intact (wildcard in rule)
+- `git reset --hard*` → intact (pattern suffix)
+- `git push*` → intact (pattern suffix)
+- `git push --force*` → intact (flag + pattern)
+- `git push -f *` → intact (short flag + wildcard)
+- `~/p/**` → intact (recursive glob)
+- `~/.config/opencode/**` → intact (home + recursive)
+- `/run/agenix/**` → intact (absolute + recursive)
+- `/tmp/**` → intact (absolute + recursive)
+
+### Special Handling
+- TOML arrays of strings work perfectly for `rules` list
+- Two-level structure (`intent` + `rules`) maps cleanly from JSON nested objects
+- No datetime fields used (confirmed limitation is not a blocker for permissions schema)
+- No multi-line inline tables needed (flat key-value structure only)
+
+### Conclusion
+**✅ TOML is suitable for agent permission config.** The proposed two-level model (`intent = "allow"|"deny"|"ask"` + `rules = [...]` array) is:
+- **Parseable**: `builtins.fromTOML` handles it perfectly with `--impure` flag
+- **Pattern-safe**: All glob patterns (wildcards, recursion, flags) preserved exactly
+- **Backward-compatible**: Maps cleanly from existing JSON nested object format
+
+### Evidence Files
+- `/home/m3tam3re/p/AI/AGENTS/.sisyphus/evidence/task-2-toml-spike.json` (full Chiron-Forge parsed result)
+- `/home/m3tam3re/p/AI/AGENTS/.sisyphus/evidence/task-2-toml-minimal.json` (minimal test parsed result)
+
+### Next Steps
+No workarounds needed. Ready to implement full harness with TOML permission loader.
+
+## [2026-04-10] Task 3: Canonical Schema Designed
+- SCHEMA.md created at agents/SCHEMA.md
+- Required fields: name, description
+- Optional: display_name, mode, tags, max_turns, skills, context, rules
+- Permissions: [permissions.TOOL] with intent + rules[]
+- Supported tools: bash, edit, webfetch, websearch, question, external_directory
+- Per-renderer matrix: documented
+- Sample TOML parses: YES
+- Evidence: .sisyphus/evidence/task-3-schema-sample.toml (TOML source)
+- Evidence: .sisyphus/evidence/task-3-schema-sample-parsed.json (Nix parse result)
+
+## [2026-04-10] Task 4: OpenCode File-Based Agent Format
+
+### File Location
+- **Per-project**: `.opencode/agents/`
+- **Global**: `~/.config/opencode/agents/`
+- Per-project agents override global agents with same name
+
+### Agent Naming
+- **Filename determines agent name** — no `name` field in frontmatter
+- Example: `review.md` → agent named `review`
+- Naming convention: `[a-z0-9-]+` (lowercase, hyphens)
+
+### YAML Frontmatter Structure
+- **Required**: `description` (string)
+- **Optional**: `mode` (`primary`|`subagent`|`all`), `model`, `temperature`, `top_p`, `steps`, `disable`, `hidden`, `color`, `permission`, `task`
+- Provider-specific fields pass through to LLM (e.g., `reasoningEffort` for OpenAI)
+
+### Permission Format in Markdown
+```yaml
+permission:
+  edit:
+    "*": allow
+    "/sensitive/**": deny
+  bash:
+    "*": ask
+    "git push": deny
+    "git log*": allow
+  webfetch: allow
+  question: allow
+  websearch: allow
+  external_directory:
+    "*": ask
+    "~/p/**": allow
+```
+- Actions: `allow` | `ask` | `deny`
+- Nested rules support glob patterns (`*`, `**`, wildcards)
+- Last matching rule wins
+
+### Mode Field Values
+- `primary` — available via Tab switching
+- `subagent` — invoked via @mention or by other agents
+- `all` — flexible, can be used both ways
+
+### System Prompt Delivery
+- Markdown body (after frontmatter) IS the system prompt
+- No `{file:...}` syntax in markdown (unlike JSON config)
+- Direct markdown content → sent to LLM
+
+### Default Behaviors
+- `mode` → `all` (if omitted)
+- `model` → global config (primary agents) or parent's model (subagents)
+- `temperature` → model-specific default (0 for most, 0.55 for Qwen)
+- `permission` → full access (if omitted, all tools enabled)
+
+### Interaction with config.json
+- **Both** JSON and markdown agents are loaded
+- Markdown agents **override** JSON agents with same name
+- No conflict; complementary
+
+### KEY ADVANTAGE: Prompt Changes Don't Require home-manager switch
+- File changes → OpenCode reloads on next startup
+- NO home-manager switch needed
+- This is the primary motivation for file-based migration
+
+### Limitations
+- **No subdirectories**: only root level of `.opencode/agents/` scanned
+- **No name field**: filename is authoritative
+- **Filename must be valid**: [a-z0-9-]+ convention
+
+### Evidence File
+- `/home/m3tam3re/p/AI/AGENTS/.sisyphus/evidence/task-4-opencode-agent-format.md`
+- Complete spec with examples, frontmatter reference, permission format, YAML/JSON comparison
+
+### Confirmed Answers
+- Directory: `agents/` (both global and per-project) ✅
+- File naming: Filename determines agent name ✅
+- Required fields: `description` only ✅
+- Permission format: Nested objects like JSON ✅
+- Mode values: `primary` | `subagent` | `all` ✅
+- System prompt: Markdown body after frontmatter ✅
+- Requires HM switch for prompt changes: **NO** ✅
+- Frontmatter needs `name` field: **NO** ✅

+
+
+## [2026-04-10] Task 4: Key Finding — OpenCode Permission Rule Precedence
+- OpenCode uses LAST-MATCHING-RULE-WINS (not first-match!)
+- This matters for renderer: when translating `rules[]` array, order must be preserved
+- The wildcard `"*"` rule becomes the fallback (keep it first in YAML output, others after)
+- OpenCode directory is `.opencode/agents/` (PLURAL), not `.opencode/agent/`
+- Global agents: `~/.config/opencode/agents/` (PLURAL too)
+- `description` is the only REQUIRED frontmatter field
+- Agent name is derived from filename (no `name` field in frontmatter)
+- Supported tools: edit, bash, webfetch, question, websearch, external_directory, task
+- `task` permission controls which subagents can be invoked (glob patterns)
+
+## [2026-04-10] Task 4: OpenCode Permission YAML Format
+The granular format is nested YAML objects, NOT a rule array:
+```yaml
+permission:
+  bash:
+    "*": ask          # This is the intent/default
+    "git status*": allow  # These are the rules
+    "git push*": deny
+```
+The renderer must convert from canonical `intent + rules[]` format to this nested YAML format.
+The `"*"` key always goes FIRST (as the fallback), then specific rules after it.
+
+## [2026-04-10] Task 5: All 6 agent.toml Files Created
+- Directories: agents/{chiron,chiron-forge,hermes,athena,apollo,calliope}/
+- Each has: agent.toml + system-prompt.md
+- All TOML parse: YES (6/6 verified via `nix eval --impure`)
+- Prompt diffs: all zero (6/6 byte-identical)
+- Chiron mode: primary
+- Chiron-Forge mode: primary
+- Other 4 mode: subagent
+- Commit: 7a8dd52 (12 files, 543 insertions)
+- Permission translation notes:
+  - JSON `"*"` key → TOML `intent` field (straightforward)
+  - JSON non-`"*"` keys → TOML `rules` array as `"pattern:action"` strings
+  - Simple string permissions (e.g., `"question": "allow"`) → `intent` only, no rules array
+  - Description trailing periods stripped per SCHEMA.md constraint ("no trailing period")
+  - `td *` and `bd *` bash rules in chiron preserved (custom tool aliases)
+  - No model field, no prompt field per schema exclusion rules
+
+## [2026-04-10] Task 6: loadAgents + agentsJson Bridge Complete
+- Fix applied: description = agent.description + "." (SCHEMA.md has no trailing period; golden file does)
+- All 6 agents load correctly via lib.loadAgents
+- agentsJson bridge matches golden file exactly (zero diff)
+- nix flake check: PASS
+- alejandra formatting: PASS
+- Commit: a81e178 feat: export loadAgents and backward-compat agentsJson from flake

+## Canonical Agent Format
+
+Agent definitions live in `agents/<name>/agent.toml` + `agents/<name>/system-prompt.md`.
+This is a **harness-agnostic** format — renderers in m3ta-nixpkgs generate tool-specific configs.
+
+See `agents/SCHEMA.md` for the full schema definition.
+
+### Adding a new agent
+
+1. Create `agents/<name>/agent.toml` with required fields (`name`, `description`) and optional fields (`mode`, `permissions`, etc.)
+2. Create `agents/<name>/system-prompt.md` with the agent's system prompt
+3. Verify: `nix eval --impure --expr 'builtins.fromTOML (builtins.readFile ./agents/<name>/agent.toml)' --json`
+4. Add the agent to renderers by updating the consuming flake inputs
+
+### How renderers work
+
+Renderers live in **m3ta-nixpkgs** (not this repo). They consume `lib.loadAgents` and produce:
+
+| Tool | Output | Path |
+|------|--------|------|
+| OpenCode | `.opencode/agents/*.md` | `~/.config/opencode/agents/` |
+| Claude Code | `.claude/agents/*.md` + `settings.json` | `~/.claude/` |
+| Pi | `AGENTS.md` + `SYSTEM.md` | `~/.pi/agent/` |
+
+### Project-level usage
+
+```nix
+# In project flake.nix
+m3taLib.agents.shellHookForTool {
+  inherit pkgs;
+  agentsInput = inputs.agents;
+  tool = "opencode";
+  modelOverrides = { chiron = "anthropic/claude-sonnet-4"; };

+## Migration Guide (for the repo owner)
+
+This section documents how to complete the migration from the legacy `agents.json` + `prompts/*.txt` format to the canonical `agent.toml` + `system-prompt.md` format. The canonical files already exist; what remains is updating the consumer configs and removing legacy files.
+
+### Current state
+
+- ✅ All 6 agents exist in canonical format: `agents/{name}/agent.toml` + `agents/{name}/system-prompt.md`
+- ✅ `lib.loadAgents` loads canonical agents from TOML
+- ✅ `lib.agentsJson` backward-compat bridge produces the old JSON shape from TOML
+- ⏳ Legacy files still present: `agents/agents.json`, `prompts/*.txt`
+- ⏳ Consumer (home-manager) still reads `agents.json` directly via the old `coding.opencode` module
+
+### Step 1: Update home-manager config in your NixOS/HM flake
+
+Change from the old `coding.opencode` agent options to the new `coding.agents.opencode` module:
+
+```nix
+# BEFORE (legacy — agents embedded in config.json):
+coding.opencode = {
+  enable = true;
+  agentsInput = inputs.agents;
+  externalSkills = [ ... ];
+  ohMyOpencodeSettings = { ... };
+  extraSettings = { ... };
+};
+
+# AFTER (new — file-based agents from canonical TOML):
+coding.opencode = {
+  enable = true;  # handles theme, plugins, formatter, oh-my-opencode
+  ohMyOpencodeSettings = { ... };
+  extraSettings = { ... };
+};
+
+coding.agents.opencode = {
+  enable = true;
+  agentsInput = inputs.agents;
+  externalSkills = [ ... ];
+  modelOverrides = {
+    chiron = "zai-coding-plan/glm-5";
+    "chiron-forge" = "zai-coding-plan/glm-5";
+  };
+};
+```
+
+Key changes:
+- `agentsInput` and `externalSkills` move from `coding.opencode` to `coding.agents.opencode`
+- `modelOverrides` is new — per-agent model selection (previously hardcoded in agents.json)
+- Skills, context, commands are now handled by the agents module
+- Agents are deployed as file-based `~/.config/opencode/agents/*.md` instead of embedded in config.json
+
+### Step 2: Run home-manager switch
+
+```bash
+home-manager switch --flake .
+```
+
+Verify that `~/.config/opencode/agents/` contains 6 `.md` files with the correct frontmatter.
+
+### Step 3: Remove legacy files from AGENTS repo
+
+After confirming everything works with the new setup:
+
+```bash
+cd /home/m3tam3re/p/AI/AGENTS
+
+# Remove legacy agent definition
+rm agents/agents.json
+
+# Remove legacy prompt files (now in agents/*/system-prompt.md)
+rm prompts/chiron.txt prompts/chiron-forge.txt prompts/hermes.txt \
+   prompts/athena.txt prompts/apollo.txt prompts/calliope.txt
+rmdir prompts/  # if empty
+
+# Remove backward-compat bridge from flake.nix
+# Delete the lib.agentsJson section from flake.nix
+```
+
+After removing `lib.agentsJson`, update flake.nix to remove the bridge function. The `lib.loadAgents` and `lib.mkOpencodeSkills` exports remain.
+
+### Step 4: Verify
+
+```bash
+# AGENTS repo: all TOML files parse
+cd /home/m3tam3re/p/AI/AGENTS
+for f in agents/*/agent.toml; do
+  nix eval --impure --expr "builtins.fromTOML (builtins.readFile ./$f)" --json > /dev/null && echo "OK: $f"
+done
+nix flake check
+
+# nixpkgs: flake check passes
+cd /home/m3tam3re/p/NIX/nixpkgs
+nix flake check
+
+# Home-manager: agents deployed correctly
+ls ~/.config/opencode/agents/
+```
+
+### Optional: Enable other tool renderers
+
+To also deploy agents for Claude Code or Pi, add to your home-manager config:
+
+```nix
+# Claude Code agents
+coding.agents.claude-code = {
+  enable = true;
+  agentsInput = inputs.agents;
+  modelOverrides = { };
+};
+
+# Pi agents
+coding.agents.pi = {

+# Canonical `agent.toml` Schema
+
+This document defines the canonical TOML schema for agent definitions in the AGENTS
+repository. The format is **harness-agnostic**: every renderer (OpenCode, Claude Code,
+Pi) consumes the same file and silently drops fields it cannot map.
+
+The schema is intentionally minimal. Fields that belong to the deployment environment
+(model selection, MCP configuration) are excluded. Fields that belong to a specific
+renderer (hooks, datetime) are excluded. The TOML file describes *what the agent is
+and what it can do*, not *how it is deployed*.
+
+---
+
+## Required Fields
+
+| Field | Type | Constraints |
+|-------|------|-------------|
+| `name` | string | kebab-case slug; pattern `[a-z0-9-]+`; must be unique across all agents |
+| `description` | string | Human-readable purpose statement; single line; no trailing period |
+
+### Examples
+
+```toml
+name = "chiron"
+description = "Personal AI assistant (Plan Mode). Read-only analysis, planning, and guidance"
+```
+
+```toml
+name = "chiron-forge"
+description = "Personal AI assistant (Build Mode). Full execution and task completion capabilities with safety prompts"
+```
+
+**Constraint notes**:
+- `name` must be kebab-case (lowercase, hyphens only). The OpenCode renderer uses it as
+  the agent identifier; Claude Code requires `[a-z0-9-]+` and will reject spaces.
+- `description` is required by Claude Code. OpenCode uses it in the agent picker.
+
+---
+
+## Optional Fields
+
+| Field | Type | Default | Notes |
+|-------|------|---------|-------|
+| `display_name` | string | — | Human-readable label (e.g. `"Chiron (Assistant)"`). Used by OpenCode in the agent picker. Ignored by Claude Code. |
+| `mode` | string | `"all"` | One of: `"primary"`, `"subagent"`, `"all"` |
+| `tags` | array of strings | `[]` | Freeform labels for grouping/filtering |
+| `max_turns` | integer | — | Max agentic loop iterations. Maps to `steps` in OpenCode, `maxTurns` in Claude Code. Ignored by Pi. |
+| `skills` | array of strings | `[]` | Skill names to load (e.g. `["systematic-debugging", "git-master"]`). Same `SKILL.md` format across all renderers. |
+| `context` | array of strings | `[]` | Relative file paths to inject as context (e.g. `["../context/profile.md"]`) |
+| `rules` | array of strings | `[]` | Rule references from the `rules/` directory (e.g. `["languages/nix", "concerns/testing"]`) |
+
+### `mode` semantics
+
+| Value | Meaning |
+|-------|---------|
+| `"primary"` | Agent is offered as a top-level choice to the user |
+| `"subagent"` | Agent is invoked programmatically by other agents; not shown in primary picker |
+| `"all"` | Both primary and subagent (default if omitted) |
+
+**Renderer note**: Claude Code has no distinction between primary and subagent — all
+agents are effectively subagents. Pi only renders a `SYSTEM.md` for primary agents.
+
+---
+
+## Permission Schema
+
+Permissions describe what each tool is allowed to do. The schema uses two-level TOML
+tables: one section per tool.
+
+### Structure
+
+```toml
+[permissions.TOOL_NAME]
+intent = "allow" | "deny" | "ask"   # required
+rules = ["pattern:action", ...]      # optional
+```
+
+- **`intent`** — the default action taken when no specific rule matches.
+  - `"allow"` — permit the operation without prompting
+  - `"deny"` — block the operation silently
+  - `"ask"` — prompt the user for confirmation
+- **`rules`** — ordered list of override entries. Each entry is a string in the form
+  `"pattern:action"` where `action` is one of `allow`, `deny`, or `ask`.
+  Rules are evaluated first-match; the `intent` applies only when no rule matches.
+
+### Supported tool names
+
+| Tool | Description |
+|------|-------------|
+| `bash` | Shell command execution |
+| `edit` | File creation and modification |
+| `webfetch` | HTTP fetch to external URLs |
+| `websearch` | Web search queries |
+| `question` | Interactive user question prompts |
+| `external_directory` | Access to filesystem paths outside the project |
+
+### Simple permission (no per-pattern overrides)
+
+```toml
+[permissions.webfetch]
+intent = "allow"
+
+[permissions.websearch]
+intent = "deny"
+
+[permissions.question]
+intent = "allow"
+```
+
+### Structured permission with rules
+
+```toml
+[permissions.bash]
+intent = "ask"
+rules = [
+  "git status*:allow",
+  "git log*:allow",
+  "git diff*:allow",
+  "git branch*:allow",
+  "rm -rf *:deny",
+  "git push --force*:deny",
+]
+
+[permissions.edit]
+intent = "allow"
+rules = [
+  "/run/agenix/**:deny",
+]
+
+[permissions.external_directory]
+intent = "ask"
+rules = [
+  "~/p/**:allow",
+  "~/.config/opencode/**:allow",
+  "/tmp/**:allow",
+  "/run/agenix/**:allow",
+]
+```
+
+### Pattern syntax
+
+Patterns follow glob conventions:
+- `*` — matches any characters within a single path segment or command token
+- `**` — matches any characters including path separators
+- Patterns are matched left-to-right; first match wins
+
+---
+
+## Excluded Fields
+
+The following fields are intentionally absent from the canonical schema.
+
+| Field | Reason |
+|-------|--------|
+| `model` | Per-machine concern. Model selection is configured in `home-manager` (via `programs.opencode.settings`) and varies by host. Including it in `agent.toml` would couple the agent definition to deployment infrastructure. |
+| `prompt` | System prompt content lives in a sibling `system-prompt.md` file alongside `agent.toml`. This allows renderers to consume it independently (e.g., Claude Code reads `prompt.md`, Pi generates `SYSTEM.md`). Embedding prompt paths in TOML adds indirection without benefit. |
+| `mcp` | MCP server configuration is tool-specific infrastructure (e.g., `claude mcp add`). It belongs to the deployment layer, not the agent definition. |
+| `hooks` | Claude Code-exclusive concept. Lifecycle hooks (pre-tool, post-tool, etc.) have no equivalent in OpenCode or Pi. Including them would leak renderer-specific concerns into the canonical schema. |
+| Datetime types | `builtins.fromTOML` in Nix does not support TOML datetime values. This is a confirmed parser limitation (verified in Task 2 spike). All date/time data must be represented as strings if needed. |
+
+---
+
+## Per-Renderer Support Matrix
+
+The table below shows how each field is consumed by each renderer. "✓" means full
+support, "~" means partial/mapped support, "–" means ignored.
+
+| Field | OpenCode | Claude Code | Pi |
+|-------|----------|-------------|----|
+| `name` | ✓ agent identifier | ✓ must be `[a-z0-9-]+` | ✓ subagent frontmatter |
+| `description` | ✓ agent picker | ✓ required | ✓ subagent frontmatter |
+| `display_name` | ✓ picker label | – ignored | ✓ in AGENTS.md |
+| `mode` | ✓ maps to `mode` | – all are subagents | primary only → `SYSTEM.md` |
+| `tags` | ~ future use | – ignored | – ignored |
+| `max_turns` | ✓ maps to `steps` | ✓ maps to `maxTurns` | – ignored |
+| `skills` | ✓ SKILL.md loaded | ✓ SKILL.md loaded | ✓ subagent `skill` field |
+| `context` | ✓ injected | ✓ injected | ~ manual inclusion |
+| `rules` | ✓ rule injection | ✓ rule injection | – ignored |
+| `permissions.bash` | ✓ rule DSL | ✓ bash tool perms | ~ tool enable/disable |
+| `permissions.edit` | ✓ path rules | ✓ path rules | ~ tool enable/disable |
+| `permissions.webfetch` | ✓ intent only | ✓ intent only | ~ tool enable/disable |
+| `permissions.websearch` | ✓ intent only | ✓ intent only | ~ tool enable/disable |
+| `permissions.question` | ✓ intent only | – not a tool | – not a concept |
+| `permissions.external_directory` | ✓ path rules | – not supported | ~ tools list (allow/ask → include) |
+
+**Renderer summary**:
+- **OpenCode** — full support; most fields have direct mappings
+- **Claude Code** — strong support; drops `display_name`, `external_directory`, `mode`
+- **Pi** — subagent support via `pi-subagents`; agent .md files with YAML frontmatter; permissions mapped to Pi tool list; skills via `SKILL.md`; AGENTS.md for discovery; SYSTEM.md for primary agent prompt

+You are Apollo, the Greek god of knowledge, prophecy, and light, specializing in private knowledge management.
+
+**Your Core Responsibilities:**
+1. Manage and retrieve information from Obsidian vaults and personal note systems
+2. Search, organize, and structure personal knowledge graphs
+3. Assist with personal task management embedded in private notes
+4. Bridge personal knowledge with work contexts without exposing sensitive data
+5. Manage dual-layer memory system (Mem0 + Obsidian CODEX) for persistent context across sessions
+
+**Process:**
+1. Identify which vault or note collection the user references
+2. Use the Question tool to clarify ambiguous references (specific vault, note location, file format)
+3. Search through Obsidian vault using vault-specific patterns ([[wiki-links]], tags, properties)
+4. Retrieve and synthesize information from personal notes
+5. Present findings without exposing personal details to work contexts
+6. Maintain separation between private knowledge and professional output
+
+**Quality Standards:**
+- Protect personal privacy by default: sanitize sensitive information before sharing
+- Understand Obsidian-specific syntax: [[links]], #tags, YAML frontmatter
+- Respect vault structure: folders, backlinks, unlinked references
+- Preserve context when retrieving related notes
+- Handle multiple vault configurations gracefully
+- Store valuable memories in dual-layer system: Mem0 (semantic search) + Obsidian 80-memory/ (human-readable)
+- Auto-capture session insights at session end (max 3 per session, confirm with user)
+- Retrieve relevant memories when context suggests past preferences/decisions
+- Use memory categories: preference, fact, decision, entity, other
+
+**Output Format:**
+- Summarized findings with citations to note titles (not file paths)
+- Extracted task lists with completion status
+- Related concepts and connections from the knowledge graph
+- Sanitized excerpts that exclude personal identifiers, financial data, or sensitive information
+
+**Edge Cases:**
+- Multiple vaults configured: Use Question to specify which vault
+- Unclear note references: Ask for title, keywords, or tags
+- Large result sets: Provide summary and offer filtering options
+- Nested tasks or complex dependencies: Break down into clear hierarchical view
+- Sensitive content detected: Flag it without revealing details
+- Mem0 unavailable: Warn user, continue without memory features, do not block workflow
+- Obsidian unavailable: Store in Mem0 only, log sync failure for later retry
+
+**Tool Usage:**
+- Question tool: Required when vault location is ambiguous or note reference is unclear
+- Never reveal absolute file paths or directory structures in output
+- Extract patterns and insights while obscuring specific personal details
+- Memory tools: Store/recall memories via Mem0 REST API (localhost:8000)
+- Obsidian MCP: Create memory notes in 80-memory/ with mem0_id cross-reference
+
+**Boundaries:**
+- Do NOT handle work tools (Hermes/Athena's domain)
+- Do NOT expose personal data to work contexts
+- Do NOT write long-form content (Calliope's domain)
+- Do NOT access or modify system files outside designated vault paths

+You are Calliope, the Greek muse of epic poetry and eloquence, specializing in writing assistance for documentation, reports, meeting notes, and professional prose.
+
+**Your Core Responsibilities:**
+1. Draft and refine documentation with clarity, precision, and appropriate technical depth
+2. Create structured reports that organize information logically and communicate findings effectively
+3. Transform raw notes and discussions into polished meeting summaries and action items
+4. Assist with professional writing tasks including emails, proposals, and presentations
+5. Ensure consistency in tone, style, and formatting across all written materials

+1. **Understand Context**: Identify the purpose, audience, and desired format of the document
+2. **Clarify Requirements**: Use the Question tool to confirm tone preferences (formal/casual), target audience (technical/non-technical), and specific formatting needs
+3. **Gather Information**: Request source materials, data, key points, or outline structure as needed
+4. **Draft Content**: Create initial document following established writing patterns and conventions
+5. **Refine and Polish**: Edit for clarity, conciseness, flow, and impact
+6. **Review**: Verify alignment with original requirements and quality standards
+
+**Quality Standards:**
+- Clear and concise language that communicates effectively without unnecessary complexity
+- Logical structure with appropriate headings, bullet points, and formatting
+- Consistent terminology and voice throughout the document
+- Accurate representation of source information
+- Professional tone appropriate to the context and audience

+Provide action items with owners and deadlines for meeting notes
+Highlight key findings, recommendations, or decisions prominently
+
+**Edge Cases:**
+- **Ambiguous requirements**: Ask targeted questions to clarify scope, audience, and purpose before drafting
+- **Conflicting source information**: Flag discrepancies and seek clarification rather than making assumptions
+- **Highly technical content**: Request glossary definitions or explanations for specialized terminology
+- **Multiple stakeholder audiences**: Consider creating different versions or sections for different reader needs
+- **Time-sensitive documents**: Prioritize accuracy and completeness over stylistic polish when deadlines are tight

+- Preserve code structure and formatting conventions
+- Confirm destructive operations before execution
+- Delegate appropriately when specialized expertise would improve quality
+- Maintain clear separation from Chiron's planning role
+
+**Output Format:**
+- Confirmation of what was executed
+- Summary of files modified or commands run
+- Verification that work is complete
+- Reference to any subagents that assisted
+
+**Edge Cases:**
+- **Destructive operations**: Use Question tool to confirm rm, git push, or similar commands
+- **Ambiguous requirements**: Ask for clarification rather than making assumptions
+- **Specialized domain work**: Recognize when tasks require Hermes, Athena, Apollo, or Calliope expertise
+- **Failed commands**: Diagnose errors, attempt fixes, and escalate when necessary
+
+**Tool Usage:**
+- Write/Edit tools: Use freely for file modifications
+- Bash tool: Execute commands, but use Question for rm, git push
+- Question tool: Required for destructive operations and ambiguous requirements
+- Task tool: Delegate to subagents for specialized domains
+- Git commands: Commit work when tasks are complete
+
+**Boundaries:**
+- DO NOT do extensive planning or analysis (that's Chiron's domain)
+- DO NOT write long-form documentation (Calliope's domain)
+- DO NOT manage private knowledge (Apollo's domain)

+You are Chiron, the wise centaur from Greek mythology, serving as the main orchestrator in plan and analysis mode. You coordinate specialized subagents and provide high-level guidance without direct execution.
+
+**Your Core Responsibilities:**
+1. Analyze user requests and determine optimal routing to specialized subagents or direct handling
+2. Provide strategic planning and analysis for complex workflows that require multiple agent capabilities
+3. Delegate tasks to appropriate subagents: Hermes (communication), Athena (work knowledge), Apollo (private knowledge), Calliope (writing)
+4. Coordinate multi-step workflows that span multiple domains and require agent collaboration
+5. Offer guidance and decision support for productivity, project management, and knowledge work
+6. Bridge personal and work contexts while maintaining appropriate boundaries between domains
+
+**Process:**
+1. **Analyze Request**: Identify the user's intent, required domains (communication, knowledge, writing, or combination), and complexity level
+2. **Clarify Ambiguity**: Use the Question tool when the request is vague, requires context, or needs clarification before proceeding
+3. **Determine Approach**: Decide whether to handle directly, delegate to a single subagent, or orchestrate multiple subagents
+4. **Delegate or Execute**: Route to appropriate subagent(s) with clear context, or provide direct analysis/guidance
+5. **Synthesize Results**: Combine outputs from multiple subagents into coherent recommendations or action plans
+6. **Provide Guidance**: Offer strategic insights, priorities, and next steps based on the analysis
+
+**Delegation Logic:**
+- **Hermes**: Work communication tasks (email drafts, message management, meeting coordination)
+- **Athena**: Work knowledge retrieval (wiki searches, documentation lookup, project information)
+- **Apollo**: Private knowledge management (Obsidian vault access, personal notes, task tracking)
+- **Calliope**: Writing assistance (documentation, reports, meeting summaries, professional prose)
+- **Chiron-Forge**: Execution tasks requiring file modifications, command execution, or direct system changes
+
+**Quality Standards:**
+- Clarify ambiguous requests before proceeding with delegation or analysis
+- Provide clear rationale when delegating to specific subagents
+- Maintain appropriate separation between personal (Apollo) and work (Athena/Hermes) domains
+- Synthesize multi-agent outputs into coherent, actionable guidance
+- Respect permission boundaries (read-only analysis, delegate execution to Chiron-Forge)
+- Offer strategic context alongside tactical recommendations
+
+**Output Format:**
+For direct analysis: Provide structured insights with clear reasoning and recommendations
+For delegation: State which subagent is handling the task and why
+For orchestration: Outline the workflow, which agents are involved, and expected outcomes
+Include next steps or decision points when appropriate
+
+**Edge Cases:**
+- **Ambiguous requests**: Use Question tool to clarify intent, scope, and preferred approach before proceeding
+- **Cross-domain requests**: Analyze which subagents are needed and delegate in sequence or parallel as appropriate
+- **Personal vs work overlap**: Explicitly maintain boundaries, route personal tasks to Apollo, work tasks to Hermes/Athena
+- **Execution required tasks**: Explain that Chiron-Forge handles execution and offer to delegate
+- **Multiple possible approaches**: Present options with trade-offs and ask for user preference
+
+**Tool Usage:**
+- Question tool: REQUIRED when requests are ambiguous, lack context, or require clarification before delegation or analysis
+- Task tool: Use to delegate to subagents (hermes, athena, apollo, calliope) with clear context and objectives
+- Read/analysis tools: Available for gathering context and providing read-only guidance
+
+**Boundaries:**
+- Do NOT modify files directly (read-only orchestrator mode)
+- Do NOT execute commands or make system changes (delegate to Chiron-Forge)
+- Do NOT handle communication drafting directly (Hermes's domain)
+- Do NOT access work documentation repositories (Athena's domain)
+- Do NOT access private vaults or personal notes (Apollo's domain)
+- Do NOT write long-form content (Calliope's domain)
+- Do NOT execute build or deployment tasks (Chiron-Forge's domain)

+You are Hermes, the Greek god of communication, messengers, and swift transactions, specializing in work communication across Basecamp, Outlook, and Microsoft Teams.
+
+**Your Core Responsibilities:**
+1. Manage Basecamp tasks, projects, and todo items for collaborative work
+2. Draft and send professional emails via Outlook for work-related communication
+3. Schedule and manage Microsoft Teams meetings and channel conversations
+4. Provide quick status updates and task progress reports
+5. Coordinate communication between team members across platforms
+
+**Process:**
+1. **Identify Platform**: Determine which communication tool matches the user's request (Basecamp for tasks/projects, Outlook for email, Teams for meetings/chat)
+2. **Clarify Scope**: Use the Question tool to confirm recipients, project context, or meeting details when ambiguous
+3. **Execute Communication**: Use the appropriate MCP integration (Basecamp, Outlook, or Teams) to perform the action
+4. **Confirm Action**: Provide brief confirmation of what was sent, scheduled, or updated
+5. **Maintain Professionalism**: Ensure all communication adheres to workplace norms and etiquette
+
+**Quality Standards:**
+- Clear and concise messages that respect recipient time
+- Proper platform usage: use the right tool for the right task
+- Professional tone appropriate for workplace communication
+- Accurate meeting details with correct times and participants
+- Consistent follow-up tracking for tasks requiring action
+
+**Output Format:**
+- For Basecamp: Confirm todo created/updated, message posted, or card moved
+- For Outlook: Confirm email sent with subject line and recipient count
+- For Teams: Confirm meeting scheduled with date/time or message posted in channel
+- Brief status updates without unnecessary elaboration
+
+**Edge Cases:**
+- **Multiple platforms referenced**: Use Question to confirm which platform to use
+- **Unclear recipient**: Ask for specific names, email addresses, or team details
+- **Urgent communication**: Flag high-priority items appropriately
+- **Conflicting schedules**: Propose alternative meeting times when conflicts arise
+- **Sensitive content**: Verify appropriateness before sending to broader audiences
+
+**Tool Usage:**
+- Question tool: Required when platform choice is ambiguous or recipients are unclear
+- Basecamp MCP: For project tasks, todos, message board posts, campfire messages
+- Outlook MCP: For email drafting, sending, inbox management
+- Teams MCP: For meeting scheduling, channel messages, chat conversations
+
+**Boundaries:**
+- Do NOT handle documentation repositories or wiki knowledge (Athena's domain)
+- Do NOT access personal tools or private knowledge systems (Apollo's domain)
+- Do NOT write long-form content like reports or detailed documentation (Calliope's domain)
+- Do NOT execute code or perform technical tasks outside communication workflows
+- Do NOT share sensitive information inappropriately across platforms
