skill-maintenance

skill-maintenance is a skill for Claude Code from meteor/agent-skills. It costs 54 tokens per session (1,671 once invoked), scanned A, original, MIT.

A maintenance guide for creating, reviewing, and updating published skills for Meteor application developers. It explains how to keep each skill focused, accurate, and consistent with the catalog's format.

In plain words
What is it for?
Adding new skills, updating existing skills, applying confirmed audit findings, and checking references, metadata, examples, and evaluation cases.
Why use it?
It helps maintainers avoid outdated guidance, duplicated coverage, incorrect boundaries, and accidental inclusion of internal contributor workflows.

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

skill-maintenance 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 6d 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 — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Maintain Meteor agent skills

Create focused, verifiable skills for Meteor application developers. Preserve the repository contract and avoid turning the catalog into a copy of the documentation.

Scope

Published skills live under skills/. Maintainer workflows live under .github/skills/ and are not release artifacts.

Before editing:

  1. Read AGENTS.md completely.
  2. Read templates/SKILL.template.md for a new skill.
  3. Read the target skill, its references, and its evaluation cases for an update.
  4. Inspect neighboring skills before changing routing or scope.

Do not copy maintainer skills from a Meteor source checkout into the public catalog. They describe framework contributor workflows, while this repository serves application developers.

Resolve a Meteor checkout

Resolve a checkout only when factual verification needs Meteor documentation, source, or tests.

  1. Prefer a path supplied by the user or task.
  2. Otherwise, use METEOR_CHECKOUT when it is set.
  3. Otherwise, inspect accessible workspace roots and direct sibling directories for candidates.
  4. Validate a candidate with git -C <path> rev-parse --show-toplevel. Confirm that v3-docs/, packages/, and tools/ exist. Prefer a Git remote that points to meteor/meteor; allow a fork when its upstream or structure is clear.
  5. Use an automatically discovered path only when exactly one candidate is credible. Report the resolved path.
  6. If no candidate or multiple candidates remain, ask the user for the Meteor checkout path. Do not clone a repository without authorization.

Never embed a machine-specific checkout path in a published skill.

Evidence order

Use evidence in this order:

  1. Current Meteor 3 documentation under the resolved checkout's v3-docs/.
  2. Meteor implementation and tests when documentation is ambiguous.
  3. Meteor checkout skills as navigation and maintenance guidance.
  4. Official release notes and pull requests for version-specific context.
  5. Community material only as labeled supporting context.

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.
