Create agents.json with 6 agent definitions (Wave 1, Task 1)

- Added all 6 agents: chiron, chiron-forge, hermes, athena, apollo, calliope
- Primary agents (2): chiron (Plan Mode), chiron-forge (Build Mode)
- Subagents (4): hermes (communications), athena (work knowledge), apollo (private knowledge), calliope (writing)
- All agents use model: zai-coding-plan/glm-4.7
- Prompt references use file pattern: {file:./prompts/<name>.txt}
- Permission structure: primaries have external_directory rules, subagents have simple question: allow
- Verified with Python JSON validation (6 agents, correct names)
- Documented patterns and learnings in notepad

+# Learnings - Chiron Agent Framework
+
+## Wave 1, Task 1: Create agents.json with 6 agent definitions
+
+### Agent Structure Pattern
+
+**Required fields per agent:**
+- `description`: Clear purpose statement
+- `mode`: "primary" for orchestrators, "subagent" for specialists
+- `model`: "zai-coding-plan/glm-4.7" (consistent across all agents)
+- `prompt`: File reference pattern `{file:./prompts/<name>.txt}`
+- `permission`: Either explicit permissions or simple "question": "allow"
+
+### Primary vs Subagent Modes
+
+**Primary agents** (2): chiron, chiron-forge
+- Can be invoked directly by user
+- Orchestrate and delegate work
+- Higher permission levels (external_directory rules)
+
+**Subagents** (4): hermes, athena, apollo, calliope
+- Invoked by primary agents via Task tool
+- Specialized single-purpose workflows
+- Simpler permission structure (question: "allow")
+
+### Permission Patterns
+
+**Primary agents**: Complex permission structure
+```json
+"permission": {
+  "external_directory": {
+    "~/p/**": "allow",
+    "*": "ask"
+  }
+}
+```
+
+**Subagents**: Simple permission structure
+```json
+"permission": {
+  "question": "allow"
+}
+```
+
+### Agent Domains
+
+1. **chiron**: Plan Mode - Read-only analysis and planning
+2. **chiron-forge**: Build Mode - Full execution with safety prompts
+3. **hermes**: Work communication (Basecamp, Outlook, Teams)
+4. **athena**: Work knowledge (Outline wiki, documentation)
+5. **apollo**: Private knowledge (Obsidian vault, personal notes)
+6. **calliope**: Writing (documentation, reports, prose)
+
+### Verification Commands
+
+**Agent count:**
+```bash
+python3 -c "import json; data = json.load(open('agents/agents.json')); print(len(data))"
+# Expected output: 6
+```
+
+**Agent names:**
+```bash
+python3 -c "import json; data = json.load(open('agents/agents.json')); print(sorted(data.keys()))"
+# Expected output: ['apollo', 'athena', 'calliope', 'chiron', 'chiron-forge', 'hermes']
+```
+
+### Key Takeaways
+
+- Prompt files use file references, not inline content (Wave 2 will create these)
+- Model is consistent across all agents for predictable behavior
+- Permission structure matches agent capability level (more complex for primaries)
+- Mode determines how agent can be invoked (direct vs delegated)
