Anthril Official Claude Plugins

A curated library of Claude Code plugins, organised into three customer-facing roots and packaged as a Claude Code marketplace.

29 catalogued plugins · 200+ production-ready skills · Australian English throughout · evidence-backed markdown outputs.

The marketplace catalogue (.claude-plugin/marketplace.json) covers everything under:

• ai-utility-plugins/ — 3 plugins
• official-business-plugins/ — 22 plugins
• official-lifestyle-plugins/ — 4 plugins

The anthril-os/ and internal-utilities/ trees in this repo are not part of the marketplace.

Maintained by @Anthril.

Quick Start

claude --plugin-dir ./official-business-plugins/engineering/software-development

# List available skills
/skills

Updating

Claude Code does not auto-refresh marketplaces — it reads from a local cache (~/.claude/plugins/marketplaces/<name>/) re-fetched on demand. To pick up a new release:

/plugin marketplace update anthril-official-claude-plugins
/plugin update software-development@anthril-official-claude-plugins

See CHANGELOG.md for what changed in each release.

Skill features

Every skill includes:

• YAML frontmatter — name, description, argument-hint, allowed-tools, effort
• $ARGUMENTS — direct user input
• Output templates under templates/
• Example outputs under examples/
• Eval suite under evals/suite.yaml (≥ 3 activation-positive, ≥ 2 activation-negative, ≥ 2 edge)

Select skills also include context: fork, paths auto-activation, dense reference.md, dynamic context injection, and parallel sub-agents.

Quality + Evaluation

• Audit — /skill-evaluator <path> (in internal-utilities/skill-ops) produces a scored markdown report + JSON sidecar across 8–10 dimensions.
• Eval suites — every skill has evals/suite.yaml.
• Harness — /skill-eval-harness <skill> runs the suite, dispatches LLM-as-judge in a fresh subagent context, and emits a markdown run report.

Validation

Before submitting changes:

node scripts/check-versions.mjs    # marketplace ↔ plugin.json version sync
node scripts/check-validate.mjs    # delegates to `claude plugin validate`

Both checks must pass green.
