commitlore-query

A skill for comparing two versions of a document and explaining their differences. It can also create a Word redline, which displays edits as tracked insertions and deletions.

In plain words
What is it for?
Use it for revised contracts, marked-up documents, change summaries, risk reviews, and tracked-change Word files.
Why use it?
It helps you quickly see what changed and judge whether the edits are merely editorial or materially affect the document.

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

commitlore-query 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.

How it starts

The opening of the file, as written. The whole thing — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CommitLore query

context, limits, ruled-out, and warnings read the same underlying record set for one or more paths; stale reads it repo-wide. All are read-only — none of them touch git state.

Reading records for a path

commitlore context src/core/types.ts
context for src/core/types.ts as of 2026-07-26T07:28:42.051Z — 2 limits, 5 ruled-out, 3 warnings, 16 other in 2 records (index, 2 commit record(s) scanned)

limits
  r-c0f4e2  3d249cd3  npm gitlore is held by an active same-domain CLI, so the owner's first-choice name was not available
  r-b2e7f1  00d348d1  Parsing must delegate to git interpret-trailers -- reimplementing the block rules would drift from the rest of the git ecosystem

ruled-out
  r-c0f4e2  3d249cd3  GitLore published as git-lore | the binary and search results still collide with the existing gitlore tool
  r-b2e7f1  00d348d1  line-matching Key: prefixes | prose containing a colon line parses as a record and feeds agents false context (verified B3)
  ...

warnings
  r-c0f4e2  3d249cd3  [directive]  ADR-0008 and ADR-0009 keep the literal string Annals on purpose -- mechanical substitution there destroys the decision trail
  ...

other
  r-c0f4e2  3d249cd3  Blast: system
  ...

context is every active record touching the path, grouped by section, each line prefixed with its Record-Id and short commit sha. limits, ruled-out, and warnings return the same underlying records filtered to one key each — reach for those when only one kind of information matters:

commitlore limits src/core/types.ts
2 limits for src/core/types.ts as of 2026-07-26T07:28:42.946Z (index, 2 commit record(s) scanned)

  r-c0f4e2  3d249cd3  npm gitlore is held by an active same-domain CLI, so the owner's first-choice name was not available
  r-b2e7f1  00d348d1  Parsing must delegate to git interpret-trailers -- reimplementing the block rules would drift from the rest of the git ecosystem

Those four take zero or more paths (commitlore context a.ts b.ts answers for both). Several paths work, but Git follows renames only for a single path. When several paths are supplied, the CLI answers each literal path and prints a diagnostic that renames were not followed; query one path at a time when historical names matter. They share these flags:

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.

commitlore-query is a skill published in the GitHub repository MongLong0214/commitlore (9 stars, last pushed 3d ago), licensed MIT. It adds 143 tokens to every session and 1,623 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
