Six independent fixes that make hook behaviour deterministic, debuggable, and free of silent footguns. Persist session_id in stored memories on_pre_compact.py now extracts session_id from the hook input and writes it under metadata.session_id, enabling search-by-session. Skip SessionStart bootstrap when MEM0_API_KEY is missing on_session_start.sh exits 0 early instead of emitting bootstrap text that instructs the agent to call mem0 MCP tools that would all fail without a key. Tighten block_memory_write.sh regex The old `*/memory/*.md` pattern blocked legitimate paths like docs/memory/architecture.md. New pattern blocks `*/MEMORY.md` and `*/.claude/memory/*` only -- the actual surfaces we want to protect. Opt-in debug logging via MEM0_DEBUG=1 Each hook (bash + python) redirects stderr / adds a FileHandler to ~/.mem0/hooks.log when MEM0_DEBUG is set. No helper module, no rotation -- KISS. Default behaviour is unchanged. Drop the duplicate PreCompact registration hooks.json and cursor-hooks.json had on_pre_compact.sh AND on_pre_compact.py registered on PreCompact, producing duplicate session-state writes. Drop the python entry. The python script stays alive -- on_stop.sh still spawns it as a session-end safety net. CI nudge Adds a single comment line to pyproject.toml because the repo's ci.yml path filters exclude mem0-plugin/-only PRs but the build_mem0/build_embedchain status checks are required by branch protection. Track the proper fix (path-conditional CI) as a follow-up.
