+# Agent Permissions Refinement
+
+## TL;DR
+
+> **Quick Summary**: Refine OpenCode agent permissions for Chiron (planning) and Chriton-Forge (build) to implement 2025 AI security best practices with principle of least privilege, human-in-the-loop for critical actions, and explicit guardrails against permission bypass.
+
+> **Deliverables**:
+> - Updated `agents/agents.json` with refined permissions for Chiron and Chriton-Forge
+> - Critical bug fix: Duplicate `external_directory` key in Chiron config
+> - Enhanced secret blocking with additional patterns
+> - Bash injection prevention rules
+> - Git protection against secret commits and repo hijacking
+
+> **Estimated Effort**: Medium
+> **Parallel Execution**: NO - sequential changes to single config file
+> **Critical Path**: Fix duplicate key → Apply Chiron permissions → Apply Chriton-Forge permissions → Validate
+
+---
+
+## Context
+
+### Original Request
+User wants to refine agent permissions for:
+- **Chiron**: Planning agent with read-only access, restricted to read-only subagents, no file editing, can create beads issues
+- **Chriton-Forge**: Build agent with write access restricted to ~/p/**, git commits allowed but git push asks, package install commands ask
+- **General**: Sane defaults that are secure but open enough for autonomous work
+
+### Interview Summary
+**Key Discussions**:
+- Chiron: Read-only planning, no file editing, bash denied except for `bd *` commands, external_directory ~/p/** only, task permission to restrict subagents to explore/librarian/athena + chiron-forge for handoff
+- Chriton-Forge: Write access restricted to ~/p/**, git commits allow / git push ask, package install commands ask, git config deny
+- Workspace path: ~/p/** is symlink to ~/projects/personal/** (just replacing path reference)
+- Bash security: Block all bash redirect patterns (echo >, cat >, tee, etc.)
+
+**Research Findings**:
+- OpenCode supports granular permission rules with wildcards, last-match-wins
+- 2025 best practices: Principle of least privilege, tiered permissions (read-only auto, destructive ask, JIT privileges), human-in-the-loop for critical actions
+- Security hardening: Block command injection vectors, prevent git secret commits, add comprehensive secret blocking patterns
+
+### Metis Review
+**Critical Issues Identified**:
+1. **Duplicate `external_directory` key** in Chiron config (lines 8-9 and 27) - second key overrides first, breaking intended behavior
+2. **Bash edit bypass**: Even with `edit: deny`, bash can write files via redirection (`echo "x" > file.txt`, `cat >`, `tee`)
+3. **Git secret protection**: Agent could commit secrets (read .env, then git commit .env)
+4. **Git config hijacking**: Agent could modify .git/config to push to attacker-controlled repo
+5. **Command injection**: Malicious content could execute via `$()`, backticks, `eval`, `source`
+6. **Secret blocking incomplete**: Missing patterns for `.local/share/*`, `.cache/*`, `*.db`, `*.keychain`, `*.p12`
+
+**Guardrails Applied**:
+- Fix duplicate external_directory key (use single object with catch-all `"*": "ask"` after specific rules)
+- Add bash file write protection patterns (echo >, cat >, printf >, tee, > operators)
+- Add git secret protection (`git add *.env*`: deny, `git commit *.env*`: deny)
+- Add git config protection (`git config *`: deny for Chriton-Forge)
+- Add bash injection prevention (`$(*`, `` `*``, `eval *`, `source *`)
+- Expand secret blocking with additional patterns
+- Add /run/agenix/* to read deny list
+
+---
+
+## Work Objectives
+
+### Core Objective
+Refine OpenCode agent permissions in `agents/agents.json` to implement security hardening based on 2025 AI agent best practices while maintaining autonomous workflow capabilities.
+
+### Concrete Deliverables
+- Updated `agents/agents.json` with:
+  - Chiron: Read-only permissions, subagent restrictions, bash denial (except `bd *`), no file editing
+  - Chriton-Forge: Write access scoped to ~/p/**, git commit allow / push ask, package install ask, git config deny
+  - Both: Enhanced secret blocking, bash injection prevention, git secret protection
+
+### Definition of Done
+- [x] Permission configuration updated in `agents/agents.json`
+- [x] JSON syntax valid (no duplicate keys, valid structure)
+- [x] Workspace path validated (~/p/** exists and is correct)
+- [x] Acceptance criteria tests pass (via manual verification)
+
+### Must Have
+- Chiron cannot edit files directly
+- Chiron cannot write files via bash (redirects blocked)
+- Chiron restricted to read-only subagents + chiron-forge for handoff
+- Chriton-Forge can only write to ~/p/**
+- Chriton-Forge cannot git config
+- Both agents block secret file reads
+- Both agents prevent command injection
+- Git operations cannot commit secrets
+- No duplicate keys in permission configuration
+
+### Must NOT Have (Guardrails)
+- **Edit bypass via bash**: No bash redirection patterns that allow file writes when `edit: deny`
+- **Git secret commits**: No ability to git add/commit .env or credential files
+- **Repo hijacking**: No git config modification allowed for Chriton-Forge
+- **Command injection**: No `$()`, backticks, `eval`, `source` execution via bash
+- **Write scope escape**: Chriton-Forge cannot write outside ~/p/** without asking
+- **Secret exfiltration**: No access to .env, .ssh, .gnupg, credentials, secrets, .pem, .key, /run/agenix
+- **Unrestricted bash for Chiron**: Only `bd *` commands allowed
+
+---
+
+## Verification Strategy (MANDATORY)
+
+> This is configuration work, not code development. Manual verification is required after deployment.
+
+### Test Decision
+- **Infrastructure exists**: YES (home-manager deployment)
+- **User wants tests**: NO (Manual-only verification)
+- **Framework**: None
+
+### Manual Verification Procedures
+
+Each TODO includes EXECUTABLE verification procedures that users can run to validate changes.
+
+**Verification Commands to Run After Deployment:**
+
+1. **JSON Syntax Validation**:
+```bash
+# Validate JSON structure and no duplicate keys
+jq '.' /home/m3tam3re/p/AI/AGENTS/agents/agents.json > /dev/null 2>&1
+# Expected: Exit code 0 (valid JSON)
+
+# Check for duplicate keys (manual review of chiron permission object)
+# Expected: Single external_directory key, no other duplicates
+```
+
+2. **Workspace Path Validation**:
+```bash
+ls -la ~/p/ 2>&1
+# Expected: Directory exists, shows contents (likely symlink to ~/projects/personal/)
+```
+
+3. **After Deployment - Chiron Read-Only Test** (manual):
+- Have Chiron attempt to edit a test file
+  - Expected: Permission denied with clear error message
+- Have Chiron attempt to write via bash (echo "test" > /tmp/test.txt)
+  - Expected: Permission denied
+- Have Chiron run `bd ready` command
+  - Expected: Command succeeds, returns JSON output with issue list
+- Have Chiron attempt to invoke build-capable subagent (sisyphus-junior)
+  - Expected: Permission denied
+
+4. **After Deployment - Chiron Workspace Access** (manual):
+- Have Chiron read file within ~/p/**
+  - Expected: Success, returns file contents
+- Have Chiron read file outside ~/p/**
+  - Expected: Permission denied or ask user
+- Have Chiron delegate to explore/librarian/athena
+  - Expected: Success, subagent executes
+
+5. **After Deployment - Chriton-Forge Write Access** (manual):
+- Have Chriton-Forge write test file in ~/p/** directory
+  - Expected: Success, file created
+- Have Chriton-Forge attempt to write file to /tmp
+  - Expected: Ask user for approval
+- Have Chriton-Forge run `git add` and `git commit -m "test"`
+  - Expected: Success, commit created without asking
+- Have Chriton-Forge attempt `git push`
+  - Expected: Ask user for approval
+- Have Chriton-Forge attempt `git config`
+  - Expected: Permission denied
+- Have Chriton-Forge attempt `npm install lodash`
+  - Expected: Ask user for approval
+
+6. **After Deployment - Secret Blocking Tests** (manual):
+- Attempt to read .env file with both agents
+  - Expected: Permission denied
+- Attempt to read /run/agenix/ with Chiron
+  - Expected: Permission denied
+- Attempt to read .env.example (should be allowed)
+  - Expected: Success
+
+7. **After Deployment - Bash Injection Prevention** (manual):
+- Have agent attempt bash -c "$(cat /malicious)"
+  - Expected: Permission denied
+- Have agent attempt bash -c "`cat /malicious`"
+  - Expected: Permission denied
+- Have agent attempt eval command
+  - Expected: Permission denied
+
+8. **After Deployment - Git Secret Protection** (manual):
+- Have agent attempt `git add .env`
+  - Expected: Permission denied
+- Have agent attempt `git commit .env`
+  - Expected: Permission denied
+
+9. **Deployment Verification**:
+```bash
+# After home-manager switch, verify config is embedded correctly
+cat ~/.config/opencode/config.json | jq '.agent.chiron.permission.external_directory'
+# Expected: Shows ~/p/** rule, no duplicate keys
+
+# Verify agents load without errors
+# Expected: No startup errors when launching OpenCode
+```

+
+## TODOs
+
+> Implementation tasks for agent configuration changes. Each task MUST include acceptance criteria with executable verification.
+
+- [x] 1. Fix Duplicate external_directory Key in Chiron Config
+
+  **What to do**:
+  - Remove duplicate `external_directory` key from Chiron permission object
+  - Consolidate into single object with specific rule + catch-all `"*": "ask"`
+  - Replace `~/projects/personal/**` with `~/p/**` (symlink to same directory)
+
+  **Must NOT do**:
+  - Leave duplicate keys (second key overrides first, breaks config)
+  - Skip workspace path validation (verify ~/p/** exists)
+
+  **Recommended Agent Profile**:
+  > **Category**: quick
+    - Reason: Simple JSON edit, single file change, no complex logic
+  > **Skills**: git-master
+    - git-master: Git workflow for committing changes
+  > **Skills Evaluated but Omitted**:
+    - research: Not needed (no investigation required)
+    - librarian: Not needed (no external docs needed)
+
+  **Parallelization**:
+  - **Can Run In Parallel**: NO
+  - **Parallel Group**: Sequential
+  - **Blocks**: Tasks 2, 3 (depends on clean config)
+  - **Blocked By**: None (can start immediately)
+
+  **References** (CRITICAL - Be Exhaustive):
+
+  **Pattern References** (existing code to follow):
+  - `agents/agents.json:1-135` - Current agent configuration structure (JSON format, permission object structure)
+  - `agents/agents.json:7-29` - Chiron permission object (current state with duplicate key)
+
+  **API/Type References** (contracts to implement against):
+  - OpenCode permission schema: `{"permission": {"bash": {...}, "edit": "...", "external_directory": {...}, "task": {...}}`
+
+  **Documentation References** (specs and requirements):
+  - Interview draft: `.sisyphus/drafts/agent-permissions-refinement.md` - All user decisions and requirements
+  - Metis analysis: Critical issue #1 - Duplicate external_directory key
+
+  **External References** (libraries and frameworks):
+  - OpenCode docs: https://opencode.ai/docs/permissions/ - Permission system documentation (allow/ask/deny, wildcards, last-match-wins)
+  - OpenCode docs: https://opencode.ai/docs/agents/ - Agent configuration format
+
+  **WHY Each Reference Matters** (explain the relevance):
+  - `agents/agents.json` - Target file to modify, shows current structure and duplicate key bug
+  - Interview draft - Contains all user decisions (~/p/** path, subagent restrictions, etc.)
+  - OpenCode permissions docs - Explains permission system mechanics (last-match-wins critical for rule ordering)
+  - Metis analysis - Identifies the duplicate key bug that MUST be fixed
+
+  **Acceptance Criteria**:
+
+  > **CRITICAL: AGENT-EXECUTABLE VERIFICATION ONLY**
+
+  **Automated Verification (config validation)**:
+  \`\`\`bash
+  # Agent runs:
+  jq '.' /home/m3tam3re/p/AI/AGENTS/agents/agents.json > /dev/null 2>&1
+  # Assert: Exit code 0 (valid JSON)
+
+  # Verify single external_directory key in chiron permission object
+  cat /home/m3tam3re/p/AI/AGENTS/agents/agents.json | jq '.chiron.permission | keys' | grep external_directory | wc -l
+  # Assert: Output is "1" (exactly one external_directory key)
+
+  # Verify workspace path exists
+  ls -la ~/p/ 2>&1 | head -1
+  # Assert: Shows directory listing (not "No such file or directory")
+  \`\`\`
+
+  **Evidence to Capture**:
+  - [x] jq validation output (exit code 0)
+  - [x] external_directory key count output (should be "1")
+  - [x] Workspace path ls output (shows directory exists)
+
+  **Commit**: NO (group with Task 2 and 3)
+
+- [x] 2. Apply Chiron Permission Updates
+
+  **What to do**:
+  - Set `edit` to `"deny"` (planning agent should not write files)
+  - Set `bash` permissions to deny all except `bd *`:
+    ```json
+    "bash": {
+      "*": "deny",
+      "bd *": "allow"
+    }
+    ```
+  - Set `external_directory` to `~/p/**` with catch-all ask:
+    ```json
+    "external_directory": {
+      "~/p/**": "allow",
+      "*": "ask"
+    }
+    ```
+  - Add `task` permission to restrict subagents:
+    ```json
+    "task": {
+      "*": "deny",
+      "explore": "allow",
+      "librarian": "allow",
+      "athena": "allow",
+      "chiron-forge": "allow"
+    }
+    ```
+  - Add `/run/agenix/*` to read deny list
+  - Add expanded secret blocking patterns: `.local/share/*`, `.cache/*`, `*.db`, `*.keychain`, `*.p12`
+
+  **Must NOT do**:
+  - Allow bash file write operators (echo >, cat >, tee, etc.) - will add in Task 3 for both agents
+  - Allow chiron to invoke build-capable subagents beyond chiron-forge
+  - Skip webfetch permission (should be "allow" for research capability)
+
+  **Recommended Agent Profile**:
+  > **Category**: quick
+    - Reason: JSON configuration update, follows clear specifications from draft
+  > **Skills**: git-master
+    - git-master: Git workflow for committing changes
+  > **Skills Evaluated but Omitted**:
+    - research: Not needed (all requirements documented in draft)
+    - librarian: Not needed (no external docs needed)
+
+  **Parallelization**:
+  - **Can Run In Parallel**: YES
+  - **Parallel Group**: Wave 2 (with Task 3)
+  - **Blocks**: Task 4
+  - **Blocked By**: Task 1
+
+  **References** (CRITICAL - Be Exhaustive):
+
+  **Pattern References** (existing code to follow):
+  - `agents/agents.json:11-24` - Current Chiron read permissions with secret blocking patterns
+  - `agents/agents.json:114-132` - Athena permission object (read-only subagent reference pattern)
+
+  **API/Type References** (contracts to implement against):
+  - OpenCode task permission schema: `{"task": {"agent-name": "allow"}}`
+
+  **Documentation References** (specs and requirements):
+  - Interview draft: `.sisyphus/drafts/agent-permissions-refinement.md` - Chiron permission decisions
+  - Metis analysis: Guardrails #7, #8 - Secret blocking patterns, task permission implementation
+
+  **External References** (libraries and frameworks):
+  - OpenCode docs: https://opencode.ai/docs/agents/#task-permissions - Task permission documentation
+  - OpenCode docs: https://opencode.ai/docs/permissions/ - Permission level definitions and pattern matching
+
+  **WHY Each Reference Matters** (explain the relevance):
+  - `agents/agents.json:11-24` - Shows current secret blocking patterns to extend
+  - `agents/agents.json:114-132` - Shows read-only subagent pattern for reference (athena: deny bash, deny edit)
+  - Interview draft - Contains exact user requirements for Chiron permissions
+  - OpenCode task docs - Explains how to restrict subagent invocation via task permission
+
+  **Acceptance Criteria**:
+
+  > **CRITICAL: AGENT-EXECUTABLE VERIFICATION ONLY**
+
+  **Automated Verification (config validation)**:
+  \`\`\`bash
+  # Agent runs:
+  jq '.chiron.permission.edit' /home/m3tam3re/p/AI/AGENTS/agents/agents.json
+  # Assert: Output is "deny"

+
+  jq '.chiron.permission.read."/run/agenix/*"' /home/m3tam3re/p/AI/AGENTS/agents/agents.json
+  # Assert: Output is "deny"
+  \`\`\`
+
+  **Evidence to Capture**:
+  - [x] Edit permission value (should be "deny")
+  - [x] Bash wildcard permission (should be "deny")
+  - [x] Bash bd permission (should be "allow")
+  - [x] Task wildcard permission (should be "deny")
+  - [x] Task allowlist keys (should show 5 entries)
+  - [x] External directory ~/p/** permission (should be "allow")
+  - [x] External directory wildcard permission (should be "ask")
+  - [x] Read /run/agenix/* permission (should be "deny")
+
+  **Commit**: NO (group with Task 3)
+
+- [x] 3. Apply Chriton-Forge Permission Updates
+
+  **What to do**:
+  - Split `git *: "ask"` into granular rules:
+    - Allow: `git add *`, `git commit *`, read-only commands (status, log, diff, branch, show, stash, remote)
+    - Ask: `git push *`
+    - Deny: `git config *`
+  - Change package managers from `"ask"` to granular rules:
+    - Ask for installs: `npm install *`, `npm i *`, `npx *`, `pip install *`, `pip3 install *`, `uv *`, `bun install *`, `bun i *`, `bunx *`, `yarn install *`, `yarn add *`, `pnpm install *`, `pnpm add *`, `cargo install *`, `go install *`, `make install`
+    - Allow other commands implicitly (let them use catch-all rules or existing allow patterns)
+  - Set `external_directory` to allow `~/p/**` with catch-all ask:
+    ```json
+    "external_directory": {
+      "~/p/**": "allow",
+      "*": "ask"
+    }
+    ```
+  - Add bash file write protection patterns (apply to both agents):
+    ```json
+    "bash": {
+      "echo * > *": "deny",
+      "cat * > *": "deny",
+      "printf * > *": "deny",
+      "tee": "deny",
+      "*>*": "deny",
+      ">*>*": "deny"
+    }
+    ```
+  - Add bash command injection prevention (apply to both agents):
+    ```json
+    "bash": {
+      "$(*": "deny",
+      "`*": "deny",
+      "eval *": "deny",
+      "source *": "deny"
+    }
+    ```
+  - Add git secret protection patterns (apply to both agents):
+    ```json
+    "bash": {
+      "git add *.env*": "deny",
+      "git commit *.env*": "deny",
+      "git add *credentials*": "deny",
+      "git add *secrets*": "deny"
+    }
+    ```
+  - Add expanded secret blocking patterns to read permission:
+    - `.local/share/*`, `.cache/*`, `*.db`, `*.keychain`, `*.p12`
+
+  **Must NOT do**:
+  - Remove existing bash deny rules for dangerous commands (dd, mkfs, fdisk, parted, eval, sudo, su, systemctl, etc.)
+  - Allow git config modifications
+  - Allow bash to write files via any method (must block all redirect patterns)
+  - Skip command injection prevention ($(), backticks, eval, source)
+

+
+  **References** (CRITICAL - Be Exhaustive):
+
+  **Pattern References** (existing code to follow):

+
+  **Commit**: YES (groups with Tasks 1, 2, 3)
+  - Message: `chore(agents): refine permissions for Chiron and Chriton-Forge with security hardening`
+  - Files: `agents/agents.json`
+  - Pre-commit: `jq '.' agents/agents.json > /dev/null 2>&1` (validate JSON)
+
+- [x] 4. Validate Configuration (Manual Verification)
+
+  **What to do**:
+  - Run JSON syntax validation: `jq '.' agents/agents.json`
+  - Verify no duplicate keys in configuration
+  - Verify workspace path exists: `ls -la ~/p/`
+  - Document manual verification procedure for post-deployment testing
+
+  **Must NOT do**:
+  - Skip workspace path validation
+  - Skip duplicate key verification
+  - Proceed to deployment without validation
+
+  **Recommended Agent Profile**:
+  > **Category**: quick
+    - Reason: Simple validation commands, documentation task
+  > **Skills**: git-master
+    - git-master: Git workflow for committing validation script or notes if needed
+  > **Skills Evaluated but Omitted**:
+    - research: Not needed (validation is straightforward)
+    - librarian: Not needed (no external docs needed)
+
+  **Parallelization**:
+  - **Can Run In Parallel**: NO
+  - **Parallel Group**: Sequential
+  - **Blocks**: None (final validation task)
+  - **Blocked By**: Tasks 2, 3
+
+  **References** (CRITICAL - Be Exhaustive):
+
+  **Pattern References** (existing code to follow):
+  - `AGENTS.md` - Repository documentation structure
+
+  **API/Type References** (contracts to implement against):
+  - N/A (validation task)
+
+  **Documentation References** (specs and requirements):
+  - Interview draft: `.sisyphus/drafts/agent-permissions-refinement.md` - All user requirements
+  - Metis analysis: Guardrails #1-#6 - Validation requirements
+
+  **External References** (libraries and frameworks):
+  - N/A (validation task)
+
+  **WHY Each Reference Matters** (explain the relevance):
+  - Interview draft - Contains all requirements to validate against
+  - Metis analysis - Identifies specific validation steps (duplicate keys, workspace path, etc.)
+
+  **Acceptance Criteria**:
+
+  > **CRITICAL: AGENT-EXECUTABLE VERIFICATION ONLY**
+
+  **Automated Verification (config validation)**:
+  \`\`\`bash
+  # Agent runs:
+
+  # JSON syntax validation
+  jq '.' /home/m3tam3re/p/AI/AGENTS/agents/agents.json > /dev/null 2>&1
+  # Assert: Exit code 0
+
+  # Verify no duplicate external_directory keys
+  cat /home/m3tam3re/p/AI/AGENTS/agents/agents.json | jq '.chiron.permission | keys' | grep external_directory | wc -l
+  # Assert: Output is "1"
+
+  cat /home/m3tam3re/p/AI/AGENTS/agents/agents.json | jq '.chiron-forge.permission | keys' | grep external_directory | wc -l
+  # Assert: Output is "1"
+
+  # Verify workspace path exists
+  ls -la ~/p/ 2>&1 | head -1
+  # Assert: Shows directory listing (not "No such file or directory")
+
+  # Verify all permission keys are valid
+  cat /home/m3tam3re/p/AI/AGENTS/agents/agents.json | jq '.chiron.permission' > /dev/null 2>&1
+  # Assert: Exit code 0
+
+  cat /home/m3tam3re/p/AI/AGENTS/agents/agents.json | jq '.chiron-forge.permission' > /dev/null 2>&1
+  # Assert: Exit code 0
+  \`\`\`
+
+  **Evidence to Capture**:
+  - [x] jq validation output (exit code 0)
+  - [x] Chiron external_directory key count (should be "1")
+  - [x] Chriton-Forge external_directory key count (should be "1")
+  - [x] Workspace path ls output (shows directory exists)
+  - [x] Chiron permission object validation (exit code 0)
+  - [x] Chriton-Forge permission object validation (exit code 0)
+
+  **Commit**: NO (validation only, no changes)

+## Success Criteria
+
+### Verification Commands
+```bash
+# Pre-deployment validation
+jq '.' /home/m3tam3re/p/AI/AGENTS/agents/agents.json > /dev/null 2>&1
+# Expected: Exit code 0
+
+# Duplicate key check
+cat /home/m3tam3re/p/AI/AGENTS/agents/agents.json | jq '.chiron.permission | keys' | grep external_directory | wc -l
+# Expected: 1
+
+# Workspace path validation
+ls -la ~/p/ 2>&1
+# Expected: Directory listing
+
+# Post-deployment (manual)
+# Have Chiron attempt file edit → Expected: Permission denied
+# Have Chiron run bd ready → Expected: Success
+# Have Chriton-Forge git commit → Expected: Success
+# Have Chriton-Forge git push → Expected: Ask user
+# Have agent read .env → Expected: Permission denied
+```
