# 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]` |
|
||
| `hooks/scripts/report-reader.mjs` | Layer 3 helper: reads sessions.jsonl with v1.0.0 backward compat |
|
||
|
||
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` (126 cases, zero npm dependencies):
|
||
|
||
```bash
|
||
node --test tests/*.test.mjs
|
||
```
|
||
|
||
| File | Cases | Coverage |
|
||
|------|-------|----------|
|
||
| `tests/session-start.test.mjs` | 5 | State init, JSONL, missing sid |
|
||
| `tests/prompt-analyzer.test.mjs` | 93 | 41 (25 negative + 12 pushback + 4 domain) patterns × 2 + thresholds + valence |
|
||
| `tests/tool-tracker.test.mjs` | 8 | Counting, burst, reminders |
|
||
| `tests/session-end.test.mjs` | 6 | Finalize, duration, flags, v1.0.0 backward compat |
|
||
| `tests/privacy.test.mjs` | 2 | Canary string + matched-phrase leak guard |
|
||
| `tests/skill-md.test.mjs` | 1 | SKILL.md cites Constitution + 5-publication framework |
|
||
| `tests/perf.test.mjs` | 8 | 4 hooks × 2 modes — enforces <50ms logic / <200ms total |
|
||
| `tests/interaction-report.test.mjs` | 3 | report-reader.mjs reads JSONL with v1.0.0 backward compat |
|
||
|
||
## Conventions
|
||
|
||
- Conventional Commits: `type(scope): description`
|
||
- English for all code, comments, and documentation
|
||
- Norwegian for project-internal communication
