commit-history

A tool for listing recent Git commits connected to coding-agent sessions. A Git commit is a saved set of code changes, while a session is one period of agent work.

In plain words
What is it for?
Use it to list commits, filter them by branch or repository, and see their session context and available change details.
Why use it?
It connects shipped code changes with the agent sessions that produced them, making recent work easier to trace.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-history 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 yesterday.

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.

Origin

This is a copy

100% identical to commit-history — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

The user wants a list of agent-linked commits. Filter args: $ARGUMENTS

Quick start

memory_commits { "branch": "main", "limit": 20 }

Expected output:

9a1b2c3 main 2026-06-07 "rotate refresh tokens" · session 7f3a9c2 (14 obs)
b21d004 main 2026-06-05 "rate limiter audit"    · session b21d004 (9 obs)

Why

Render only the commits the tool returned, newest first. An empty result means the filter matched nothing, not that work is missing.

Workflow

  1. Parse $ARGUMENTS for branch=<name>, repo=<url-or-fragment>, limit=<n>. A bare numeric token is the limit. Defaults: no branch, no repo, limit 100, max 500.
  2. Call memory_commits with the parsed filters.
  3. Render reverse-chronologically: short sha, branch, authored timestamp, first line of the message, linked session id(s) (first 8) with observation counts, and file count when files is present.
  4. Empty result: tell the user the filter matched nothing and suggest dropping the branch or repo filter.

Anti-patterns

WRONG (REST fallback): concatenate ?branch= + raw branch name, so a name with ?, &, or # corrupts the query string.

RIGHT: URL-encode every value with URLSearchParams/encodeURIComponent before appending to GET /agentmemory/commits.

Checklist

  • Filters parsed; bare number treated as limit; limit capped at 500.
  • Output is reverse-chronological.
  • Session ids and observation counts come straight from the response.
  • REST fallback URL-encodes branch, repo, and limit.

See also

  • commit-context: drill into one commit's session.
  • recall: search the observations behind a linked session.

Troubleshooting

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

Files

What ships with it

1 file 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.
