M Save

m_save

Write a complete, self-contained snapshot of the current work to .m_last_task.md in the project root. This is the standing "last task" file — always one file, always overwritten. Its counterpart /m_go reads it in a fresh session and continues.

Inputs

• $ARGUMENTS (optional): extra notes to include verbatim in the snapshot (e.g. "stop after step 3", a hint for the next session).

Rules

• Write for a stranger. The next session has NONE of this conversation. No "as discussed above", no shorthand invented mid-chat. Every file mentioned gets its full repo-relative path; every command is copy-pasteable.
• One standing file. Always .m_last_task.md at the project root. Overwrite what's there — do not append, do not create dated copies. (If the current file describes a different unfinished task, mention that in one line under "Previous task" so it isn't silently lost.)
• No secrets. Never write tokens, passwords, keys, or prod credentials into the file — reference the secret's name/location (env var, vault entry) instead.
• Gitignore: if .m_last_task.md is not covered by .gitignore, append it (create .gitignore if missing) — this file is personal working state, not repo content. Skip silently if already ignored.
• If an .m_plan// run is active, don't duplicate its content — link the slug and state which step/V-* row you're on; 09_verification.md stays the oracle.

Snapshot format

# Last task — 
_Saved:  · branch:  · last commit: _

## Task

## State
- ✅ Done: 
- 🔧 In progress: 
- ⏭ Next step: 

## Key files
- `` — 

## Decisions & context

## Blockers / open questions

## How to verify

## Plan link (if any)
/` — current step N, open `V-*` rows — or "none".>

## Notes

Fill every section; write "none" rather than deleting a heading. Get branch/commit from git branch --show-current and git log -1 --oneline; if not a git repo, write "no git".

Procedure

1. Gather: current task and conversation state (from context), git status/git log -1/branch, any active .m_plan//.
2. Write .m_last_task.md per the format above (overwrite).
3. Ensure it's gitignored (rule above).
4. Confirm to the user in 2–3 lines: where it was saved and what the recorded "next step" is. Do not dump the whole file back into chat.
