+# Interaction Awareness — Developer Reference
+
+Claude Code plugin for AI interaction pattern awareness.
+
+## Architecture
+
+Four layers, each building on the previous:
+
+- **Layer 1** (`skills/`) — SKILL.md behavioral overrides. Always active.
+- **Layer 2** (`hooks/scripts/`) — Programmatic detection via 4 hook events.
+  Node.js (`.mjs`), cross-platform. Writes JSONL metadata to `${CLAUDE_PLUGIN_DATA}`.
+- **Layer 3** (`commands/`) — User-triggered reports from Layer 2 data. Opt-in.
+- **Layer 4** (`commands/interaction-report.md` Step 9) — Contemplative references. Opt-in.
+
+## Key files
+
+| File | Purpose |
+|------|---------|
+| `hooks/scripts/lib.mjs` | Shared library: stdin, paths, thresholds, state, cooldowns, layer guards |
+| `hooks/scripts/session-start.mjs` | SessionStart: register session, count daily, night check |
+| `hooks/scripts/prompt-analyzer.mjs` | UserPromptSubmit: pattern flags (NEVER logs prompt text) |
+| `hooks/scripts/tool-tracker.mjs` | PostToolUse: events, edit ratio, burst, alerts |
+| `hooks/scripts/session-end.mjs` | SessionEnd: finalize JSONL, cleanup state |
+| `hooks/hooks.json` | Hook event registration (4 events) |
+| `skills/ai-psychosis/SKILL.md` | Layer 1 behavioral instructions |
+| `commands/interaction-report.md` | Layer 3 slash command: `/interaction-report [weekly\|monthly\|all]` |
+
+Legacy bash scripts were removed in v1.0 (available in git history).
+
+## Data storage
+
+```
+${CLAUDE_PLUGIN_DATA}/
+├── sessions.jsonl       Compact JSONL, one record per session
+├── events.jsonl         {ts, session_id, tool_name} per tool call
+└── state/
+    └── {session_id}.json    Live state during active session
+```
+
+State files are created at SessionStart and deleted at SessionEnd.
+
+## Hard constraints
+
+- **Cross-platform** — Node.js only, no bash/jq dependency
+- **Privacy** — prompt text NEVER written to disk. Boolean flags only.
+- **Performance** — hooks must complete in <100ms
+- **Non-blocking** — never exit 2, never require confirmation
+- **No network** — everything local
+- **Zero npm dependencies** — Node.js stdlib only (fs, path, os)
+
+## Layer configuration
+
+Global config at `~/.claude/ai-psychosis.local.md`, or per-project override at `<project>/.claude/ai-psychosis.local.md`:
+
+```yaml
+---
+layer2: true   # default on
+layer3: false  # default off
+layer4: false  # default off
+---
+```
+
+`requireLayer(N)` in lib.mjs exits with `{"continue": true}` if layer N is disabled.
+
+## Testing
+
+Automated test suite using `node:test` (73 cases, zero npm dependencies):
+
+```bash
+node --test tests/*.test.mjs
+```
+
+| File | Cases | Coverage |
+|------|-------|----------|
+| `tests/session-start.test.mjs` | 4 | State init, JSONL, missing sid |
+| `tests/prompt-analyzer.test.mjs` | 56 | 25 patterns × 2 + 6 thresholds |
+| `tests/tool-tracker.test.mjs` | 8 | Counting, burst, reminders |
+| `tests/session-end.test.mjs` | 4 | Finalize, duration, flags |
+| `tests/privacy.test.mjs` | 1 | Canary string never on disk |
+
+## Conventions
+
+- Conventional Commits: `type(scope): description`
+- English for all code, comments, and documentation
+- Norwegian for project-internal communication
