Summary
AI summaryFixed hooks executing the wrong myco version from PATH, which blocked /compact.
Full changelog
Myco v0.4.4 — Hook hotfix
Fixed issue
If you had any older myco on your PATH (Anaconda, system Python, a
stale venv, a prior v0.3.x install), the SessionStart and PreCompact
hooks would silently hit the wrong version, fail with
"invalid choice: ", and block /compact.
Root cause: hook commands used the bare myco name, which resolves
through PATH. A pre-v0.4 myco earlier on PATH shadows the current
install and rejects --project-dir (a v0.4 flag).
The fix
Both hooks/hooks.json (plugin bundle) and
.claude/settings.local.json (repo dogfooding config) now invoke
python -m myco --json ... instead of myco --json .... Dispatching
through python -m finds the correct package via sys.path, not
PATH, so stale console scripts cannot win.
Upgrade
pip install --upgrade 'myco[mcp]'
If you installed the plugin via myco-install, re-run it, or
hand-edit the command field in your hook config to prefix
python -m before myco.

About Battam1111/Myco
Agent-first cognitive substrate with 18 manifest-driven verbs (germinate / eat / assimilate / sporulate / traverse / immune / molt / …) and 25 lint dimensions enforcing contract invariants mechanically (R1–R7). Cross-session / cross-project memory via a self-validating filesystem graph — AST + markdown-link derived, not embedding-based. Provider-agnostic by design: MP1/MP2 dims forbid LLM-SDK imports in the kernel and plugin tree. Editable-default install. Works with Claude Code, Cursor, Windsurf, Zed, VS Code, and any MCP client.
