@bacnh85/pi-munin

Pi extension that exposes Munin long-term memory as native Pi tools.

Install

pi install npm:@bacnh85/pi-munin

Configuration

• MUNIN_API_KEY (required)
• MUNIN_PROJECT (required)
• MUNIN_BASE_URL (optional, defaults to https://munin.kalera.ai)

Configuration precedence is explicit tool parameters, process environment, trusted project .env.local/.env, then Pi-global .env.local/.env. Project env files are read only when ctx.isProjectTrusted() is true. Env files are parsed without mutating process.env; .env.local wins over .env at each location.

The Pi global config directory honors $PI_CODING_AGENT_DIR when set; otherwise the extension checks ~/.pi/agent and legacy ~/.pi/agents. Base URLs must be HTTP(S), cannot contain credentials, and a tool-level base_url override requires a tool-level api_key so ambient credentials are never sent to a model-selected endpoint.

Always-on Memory Protocol

When Munin is configured, pi-munin injects the condensed always-on Memory Protocol (Before acting / What to store / Memory shape / Lifecycle and safety) into the system prompt via a before_agent_start hook. This travels with the package — no edits to ~/.pi/agent/AGENTS.md are required — and carries zero overhead when pi-munin is not loaded. The full deep reference is in skills/munin/SKILL.md.

Tools

• munin_search — search memories.
• munin_get — retrieve one memory by key.
• munin_store — store verified durable knowledge.
• munin_list — list stored memories.
• munin_recent — list recently updated memories.
• munin_delete — delete a memory after interactive confirmation.
• munin_capabilities — inspect server capabilities.
• munin_share — share memories with other projects after interactive confirmation.

Delete and share safely cancel in non-interactive modes, where Pi cannot obtain confirmation.

Notes

• Treat retrieved memories as leads, not authority. Verify against current repository evidence before relying on them.
• Never store secrets, credentials, tokens, private keys, or sensitive connection strings.
• @kalera/munin-sdk@1.5.0 exposes no client-side encryption-key or crypto-helper API. This extension does not implement or claim client-side E2EE; use a future official SDK integration when one is available.

Troubleshooting

• Missing SDK dependency (Cannot find module '@kalera/munin-sdk'): when using this repository as a local Pi extension, install runtime dependencies with npm install --prefix pi-munin, then restart Pi or run /reload.
• Missing credentials: run /munin-status or set MUNIN_API_KEY and MUNIN_PROJECT.
• Auth, validation, feature, rate-limit, network, timeout, and stale-protocol errors are surfaced as typed tool errors.
• Transient network, timeout, and rate-limit failures are retried automatically with exponential backoff (3 retries).
