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 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.

Dart Package Maintenance

Guidelines for maintaining Dart packages in alignment with Dart team best practices.

Versioning

Semantic Versioning

  • Major: Breaking changes.
  • Minor: New features (non-breaking API changes).
  • Patch: Bug fixes, documentation, or non-impacting changes.
  • Unstable packages: Use 0.major.minor+patch.
  • Recommendation: Aim for 1.0.0 as soon as the package is stable.

Pre-Edit Verification

  • Check Published Versions: Before modifying CHANGELOG.md or pubspec.yaml, ALWAYS check the currently released version (e.g., via git tag or pub.dev).

  • Do Not Amend Released Versions: Never add new entries to a version header that corresponds to a released tag.

  • Increment for New Changes: If the current version in pubspec.yaml matches a released tag, increment the version (e.g., usually to -wip) and create a new section in CHANGELOG.md.

    • Consistency: The CHANGELOG.md header must match the new pubspec.yaml version.

    • SemVer Guidelines:

      • Breaking Changes: Bump Major, reset Minor/Patch (e.g., 2.0.0-wip, 0.5.0-wip).
      • New Features: Bump Minor, reset Patch (e.g., 1.1.0-wip, 0.4.5-wip).
      • Bug Fixes: Bump Patch (e.g., 1.0.1-wip).

Work-in-Progress (WIP) Versions

  • Immediately after a publish, or on the first change after a publish, update pubspec.yaml and CHANGELOG.md with a -wip suffix (e.g., 1.1.0-wip).
  • This indicates the current state is not yet published.

Breaking Changes

  • Evaluate the impact on dependent packages and internal projects.
  • Consider running changes through internal presubmits if possible.
  • Prefer incremental rollouts (e.g., new behavior as opt-in) to minimize downstream breakage.

Publishing Process

  1. Preparation: Remove the -wip suffix from pubspec.yaml and CHANGELOG.md in a dedicated pull request.
  2. Execution: Run dart pub publish (or flutter pub publish) and resolve all warnings and errors.
  3. Tagging: Create and push a git tag for the published version:
    • For single-package repos: v1.2.3
    • For monorepos: package_name-v1.2.3
    • Example: git tag v1.2.3 && git push --tags

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.
