githits-package

Instructions for using the GitHits command-line tool to inspect software packages and their dependencies. They cover versions, licenses, repository health, vulnerabilities, advisories, dependency graphs, changelogs, release notes, and upgrade reviews.

In plain words
What is it for?
Use them to investigate a package, compare versions, review vulnerabilities, trace dependencies, read changelogs, or plan an upgrade with the GitHits CLI.
Why use it?
They provide a consistent way to check package facts before making dependency decisions. They also explain package naming, authentication, terms acceptance, and version-related command rules.

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

githits-package 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Use GitHits package intelligence before making dependency claims from memory.

CLI Invocation

  • Run commands as githits ....
  • If githits is not found, retry the same command as npx -y githits@latest ....
  • Use --json when comparing versions, counting vulnerabilities, or extracting fields.
  • Do not expose credentials. If auth is required interactively, run githits login; use githits login --no-browser only when the user can complete the printed URL flow. In noninteractive eval/CI, do not start OAuth; report that GITHITS_API_TOKEN or prior login is required.
  • If a command returns TERMS_ACCEPTANCE_REQUIRED, run githits settings terms accept or use the returned authenticated acceptance URL, then retry once.

Package Spec

  • Most package commands use <registry>:<name>[@<version>], for example npm:[email protected] or pypi:requests.
  • pkg info always reports the latest published version and does not accept a version pin.
  • pkg changelog accepts <registry>:<name> or --repo-url <url>; do not pass <spec>@<version> to changelog. Use --to <version> instead.

Core Commands

githits pkg info npm:express
githits pkg info npm:express --verbose --json

githits pkg vulns npm:[email protected] --severity high
githits pkg vulns npm:lodash --scope all --include-withdrawn --json
githits pkg vulns npm:[email protected] --scope non_affecting

githits pkg deps npm:express
githits pkg deps npm:express --lifecycle all
githits pkg deps npm:express --depth 3 --json

githits pkg changelog npm:express --limit 3
githits pkg changelog npm:express --from 4.18.0 --to 4.19.0
githits pkg changelog --repo-url https://github.com/expressjs/express --limit 2 --no-body

githits pkg upgrade-review npm:[email protected] --to 4.4.3
githits pkg upgrade-review --package npm:[email protected] --package npm:[email protected] --json

Decision Flow

  • Need current package health: start with githits pkg info <registry:name>.
  • Need security status for a specific installed version: use githits pkg vulns <registry:name@version>.
  • Need historical advisories that do not affect the inspected version: use pkg vulns --scope non_affecting; use --scope all for affected plus historical rows.
  • Need dependency footprint: start with pkg deps; add --lifecycle all for non-runtime groups and --depth <n> for aggregate transitive graph data.
  • Need upgrade evidence for dependency updates, outdated package bumps, or lockfile changes: prefer pkg upgrade-review because it compares current vs target vulnerabilities, changelog range evidence, deprecation metadata, peer changes, dependency changes, and transitive security evidence by default. It reports facts only; you still own the final assessment.
  • Need release notes without a current-to-target comparison: use pkg changelog; use --from/--to for ranges and --no-body for compact timelines.

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.

githits-package is a skill published in the GitHub repository githits-com/githits-cli (87 stars, last pushed 4d ago), licensed Apache-2.0. It adds 73 tokens to every session and 1,295 once invoked, about $0.0004 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 2026-08-30.
