package-updater-update-package is a skill for Claude Code from tony/skills. It costs 27 tokens per session (1,789 once invoked), scanned A, original, MIT.

A workflow for moving one named software dependency to a chosen version everywhere it is fixed in one repository or across several repositories.

In plain words
What is it for?
Use it to update one library in files such as package manifests, requirements files, Cargo.toml, or go.mod, while preparing the related commit and follow-up work.
Why use it?
It prevents missed version pins and keeps the update record clear for each repository affected.

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

package-updater-update-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 10d 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 — 175 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Update one package

Move one named package to a target version wherever it is pinned, with a body that says what the release means for each repository it lands in.

Use the package-updater-updating-packages skill for the phase structure, and its references: references/repo-scope.md, references/ecosystems.md, references/commit-conventions.md, references/upstream-links.md, and references/follow-ups.md.

For a full sweep, use the package-updater-update skill. For a runtime or toolchain pin, use the package-updater-update-toolchain skill.

User arguments: $ARGUMENTS

Context

Repository — run this command and read the output:

git remote get-url origin 2>/dev/null || echo "(not a git repository)"

Default branch — run this command and read the output:

git symbolic-ref --short refs/remotes/origin/HEAD 2>/dev/null || echo "(unknown)"

Manifests that could pin it — run this command and read the output:

out=$(git ls-files -- 'pyproject.toml' '**/pyproject.toml' 'requirements*.txt' 'package.json' '**/package.json' 'Cargo.toml' 'go.mod' 2>/dev/null | grep -v node_modules | head -30); if [ -n "$out" ]; then echo "$out"; else echo "(none found)"; fi

Cooldown configuration — run this command and read the output:

out=$({ grep -hi 'minimumReleaseAge\|min-release-age' pnpm-workspace.yaml .npmrc; grep -hi 'exclude-newer' uv.toml pyproject.toml "${UV_CONFIG_FILE:-$HOME/.config/uv/uv.toml}"; } 2>/dev/null); if [ -n "$out" ]; then echo "$out"; else echo "(no cooldown configured)"; fi

Procedure

1. Resolve the target and confirm it exists

If the user named a version, use it. Otherwise take the latest stable release. Either way confirm it is published and record its publication timestamp — you need it to reason about the cooldown, and a version written before it is confirmed to exist is the expensive failure this ordering prevents.

If the cooldown currently hides it, say when it becomes visible and stop rather than exempting it. Exempt only when the release is needed now, and then per the exemption protocol in the ecosystems reference: narrow, annotated, its own commit, reverted when the block lapses.

What ships with it

5 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.
