| name | gtm-session |
| description | Open or close an isolated second-brain write session (worktree + PR). Use before writing when multiple agents share one knowledge remote. |
gtm-session
When
- More than one agent or machine writes the shared second brain
- The current project worktree is not the knowledge repo
- The user asks to isolate writes, open a knowledge PR, or avoid clobbering main
Open
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/brain_session.py" open \
--repo . \
--bundle knowledge \
--actor "${SECOND_BRAIN_IDENTITY:?claim an identity first}" \
--plugin gtm-positioning \
--host claude-code
Export SECOND_BRAIN_ROOT and BRAIN_SESSION_ID from the JSON. All writes go to that bundle via gtm_common.py write --author.
Close
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/brain_session.py" close \
--repo . \
--session "${BRAIN_SESSION_ID}"
Pushes to whatever remote the checkout already has and opens a PR when gh is available. Never force-push. Never invent a remote URL.
Rules
- Read shared truth from main. Overlay this session only.
- Do not pack other agents' open branches.
- See second-brain-core
docs/ISOLATION.md.
