Trace a file, function, or line back to the agent session that produced its current commit. Use when the user asks "why is this code here", "what was the agent doing when this changed", "who wrote this", or wants context on a specific location in the codebase.

AI-generated overview

Traces a file, function, or line back to the agent session behind its current commit using git blame and a memory lookup.

What it does
The skill takes a file, function, or line reference and finds the commit SHA with git blame or git log, then looks that SHA up through a memory_commit_lookup call. It presents the commit details, any linked agent session, and high-importance observations, and it reports when a commit predates session linking instead of inventing intent.
When to use it
Use it when someone asks why a piece of code is there, what an agent was doing when a location changed, or who wrote a specific line. It suits questions about the history and session context of a particular spot in a codebase.
Requirements
Requires a git repository and the git command line, plus access to the memory_commit_lookup and memory_recall tools. It ships no scripts; it is instructions only.

The user wants commit context for: $ARGUMENTS

Quick start

bash
git blame -L 40,52 src/auth/refresh.ts   # -> SHA 9a1b2c3d
json
memory_commit_lookup { "sha": "9a1b2c3d4e5f60718293a4b5c6d7e8f901234567" }

Expected output:

text
9a1b2c3 on main by dev: "rotate refresh tokens"Linked session 7f3a9c2 "Auth refresh rework", 14 obs.

Why

Report only what git and the lookup return. When the lookup gives commit: null, the commit predates session linking; do not invent intent.

Workflow

  1. Find the SHA: git blame -L <start>,<end> <file> for a line range; git log -L :<function>:<file> for a function; git log -n 1 -- <file> for a bare path.
  2. Look it up: memory_commit_lookup { "sha": "<full-sha>" }.
  3. Present the commit (sha, short sha, branch, author, message), the linked session(s) (id, project, started/ended, observation count, summary), and the importance >= 7 observations via memory_recall when available.

Anti-patterns

WRONG: lookup returns { "commit": null }, you narrate "the agent was refactoring auth" from the diff alone.

RIGHT: "This commit predates session linking, so there is no recorded agent session. From git show: it changed token rotation in refresh.ts."

Checklist

  • SHA came from git blame/log, not a guess.
  • commit: null reported as "predates linking", no fabricated session.
  • Session details quote the lookup response verbatim.
  • No intent claimed beyond what observations state.

See also

  • commit-history: list many agent-linked commits at once.
  • recall: dig deeper into the linked session's observations.

Troubleshooting

See ../_shared/TROUBLESHOOTING.md if memory_commit_lookup is not available.
