A pi extension for reading and writing persistent memory across agent systems.
Reads its own canonical store (project ./.pi/memory/ + user ~/.pi/memory/, typed
markdown with frontmatter — Claude's user/feedback/project/reference taxonomy)
AND other agents' memory verbatim (Claude CLAUDE.md + ~/.claude/projects/<slug>/
memory/, Copilot, AGENTS.md, GEMINI.md, Aider CONVENTIONS.md). Writes only ever
touch the canonical store; foreign files are never modified.
Surfaces: memory_read / memory_search / memory_write / memory_forget tools,
/memory-* commands, and a canonical index appended to the system prompt at
agent start.
Enum-valued args (type/scope/system) are lenient strings normalized in-tool
rather than anyOf/const unions: some local models emit const-union values
JSON-quoted (e.g. "\"feedback\""), which strict schema validation rejected
before the tool ran. normalizeEnumArg strips the stray quoting; memory_read by
name also falls back to a foreign file of that name.
store.ts / sources.ts import only Node built-ins so tests load them directly
under --experimental-strip-types. 31 unit tests.
