dart-package-maintenance

dart-package-maintenance is a skill for Claude Code, Codex from kevmoo/dash_skills. It costs 47 tokens per session (1,660 once invoked), scanned A, original, Apache-2.0.

A maintenance guide for external Dart packages, covering version numbers, changelogs, releases, and pull requests. It explains semantic versioning, where major, minor, and patch changes communicate the size of an update.

In plain words
What is it for?
Use it when updating, versioning, publishing, or reviewing changes to a Dart package.
Why use it?
It helps prevent changelog and package-version mistakes, especially when preparing a release or changing an already published package.

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

dart-package-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 25d 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.

Dart Package Maintenance

Guidelines for maintaining Dart packages in alignment with the canonical Dart team External Package Maintenance specification.

When to use this skill

Use this skill when:

  • Updating Dart packages, preparing for a release, or managing collaborative changes in a repository.
  • Managing versioning, CHANGELOG.md synchronization, and publishing workflows.
  • Ensuring published packages comply with Dart team conventions.

When NOT to use (Abstention Guardrails)

Do NOT apply package maintenance version bumps or changelog updates when:

  • Internal / Private Packages: Packages marked publish_to: none in pubspec.yaml that are not published to pub.dev (e.g., application root packages or internal monorepo tooling).
  • Repository-Root Files or Historical CHANGELOG.md Typos: Pull requests that only modify repository-level files outside a published package (such as .github/workflows/, repo-root SKILL.md, or root docs in a monorepo) or that only fix typos/formatting in historical CHANGELOG.md sections.
  • In-Flight PR Commits: Intermediate commits on an active feature branch where the version already carries an appropriate -wip suffix.

Versioning

Semantic Versioning

Dart packages use semantic versioning with a pre-1.0.0 variation where the version numbers are shifted to the right before a 1.0.0 release; see also the package:pub_semver semantics:

  • Packages at 1.0.0 or later: major.minor.patch.
  • Packages not yet at 1.0.0: 0.major.minor, where the second number is bumped for breaking changes, such as 0.4.2 to 0.5.0-wip, and the third number is bumped for non-breaking features and bug fixes, such as 0.4.2 to 0.4.3-wip. Avoid +1 build suffixes (in package:pub_semver, 0.4.2+1-wip parses +1-wip as build metadata rather than a -wip pre-release).
  • Recommendation: Aim to publish 1.0.0 as soon as the package is stable.

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.
