commit-context

commit-context is a skill for Claude Code from rohitg00/agentmemory. It costs 61 tokens per session (576 once invoked), scanned A, original, Apache-2.0.

A way to trace a file, function, or line of code back to the agent session that produced its current commit. A commit is a saved set of changes in Git.

In plain words
What is it for?
It helps investigate code origins, review blame or function history, inspect the related commit, and find important observations from the linked session.
Why use it?
It helps explain why code exists by connecting its change history with recorded session context, when that link is available.

About the project

agentmemory is a persistent-memory system that lets AI coding agents retain and search information across sessions. It connects with several coding agents and MCP clients, storing knowledge with confidence scoring, lifecycle handling, knowledge graphs, and hybrid search. The catalogue contains agentmemory integrations such as skills, hooks, commands, a plugin, and an MCP component.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

commit-context scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

The user wants commit context for: $ARGUMENTS

Quick start

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

Expected output:

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 TROUBLESHOOTING.md if memory_commit_lookup is not available.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
