It is built for workflows such as `/grill-with-docs`, `/tdd`, `/handoff`, and custom project skills where the same architectural decisions and project preferences need to survive across separate sessions. + +The bridge has two jobs: + +1. Before a skill starts, recall relevant project memories and print a compact context block that can be injected into the prompt. +2. After a skill finishes, extract durable engineering facts from the request and result, then store them for future skill runs. + +The example works in two modes: + +- Local mode: deterministic JSON storage for validation, demos, and CI. +- Live mode: optional Memanto/Moorcheh storage when `MOORCHEH_API_KEY` is present. + +## Why this solves the bounty + +The common failure mode in skill-based workflows is context fragmentation. A review skill may discover that a service must stay within the free tier, but a later implementation skill does not know that. This bridge preserves those decisions as reusable memory. + +It is intentionally small: + +- No changes to the main Memanto package are required. +- The hook accepts JSON from stdin, so it can be wired into Claude Code hooks, shell wrappers, or other skill runners. +- The recall step uses a strict character budget so the injected memory block stays concise. +- The write step only stores durable engineering guidance, not raw transcripts or secrets. + +## Files + +```text +examples/claudecode-skills-memanto/ +├── README.md +├── .env.example +├── settings.example.json +├── validate_offline.py +├── skill_memory_bridge/ +│ ├── __init__.py +│ ├── bridge.py +│ └── cli.py +└── tests/ + └── test_bridge.py +``` + +## Quick validation + +Run the offline proof from the repository root: + +```bash +python examples/claudecode-skills-memanto/validate_offline.py +``` + +Expected output: + +```text +offline validation passed +``` + +Run the focused tests: + +```bash +python -m pytest examples/claudecode-skills-memanto/tests -q +``` + +## Claude Code hook setup + +Copy the example settings into your Claude Code settings file, then adjust paths for your machine: + +```bash +cp examples/claudecode-skills-memanto/settings.example.json ~/.claude/settings.json +``` + +The important parts are: + +- `UserPromptSubmit` calls `cli.py pre` and injects recalled memory. +- `Stop` calls `cli.py post` and stores durable decisions from the completed run. + +The hook reads JSON from stdin. If your runner uses a different event shape, keep the same fields when possible: + +```json +{ + "skill": "/tdd", + "project": "billing-api", + "file_path": "src/billing/routes.py", + "input": "Add invoice retry tests.", + "output": "Implemented tests. Keep Stripe calls mocked in unit tests." +} +``` + +## Live Memanto mode + +Local mode is the default. To use the Memanto backend, create a free Moorcheh API key and set: + +```bash +export MOORCHEH_API_KEY="..." +export MEMANTO_SKILLS_AGENT_ID="claude-skills-memory" +export MEMANTO_SKILLS_BACKEND="memanto" +``` + +When live mode is enabled, the bridge stores memories through the Memanto Python package. If the live backend is unavailable, the CLI exits with a clear error instead of silently dropping memory. + +## Demo transcript + +First skill run stores architectural guidance: + +```bash +printf '%s' '{ + "skill": "/grill-with-docs", + "project": "support-api", + "file_path": "src/support/router.py", + "input": "Review the API design.", + "output": "Decision: keep FastAPI endpoints async. Preference: do not add paid services. Constraint: redact customer emails in logs." +}' | python examples/claudecode-skills-memanto/skill_memory_bridge/cli.py post +``` + +Later, a different skill receives the relevant context: + +```bash +printf '%s' '{ + "skill": "/tdd", + "project": "support-api", + "file_path": "src/support/tests/test_router.py", + "input": "Write tests for the support ticket route." +}' | python examples/claudecode-skills-memanto/skill_memory_bridge/cli.py pre +``` + +Example injected block: + +```text + +- Keep FastAPI endpoints async. +- Do not add paid services. +- Redact customer emails in logs. + +``` + +## Safety behavior + +The extractor is conservative by design. It stores lines that look like durable decisions, preferences, constraints, or project facts. It skips secrets, tokens, passwords, and raw low-signal transcript text. This keeps the memory layer useful without turning it into an unsafe session recorder. diff --git a/examples/claudecode-skills-memanto/requirements.txt
