Anthril Official Claude Plugins

A curated library of Claude Code plugins for data analysis, entity modelling, business operations, brand management, marketing, developer tooling, database design, and DevOps — packaged as a Claude Code marketplace with standalone plugins.

Maintained by @Anthril.

Quick Start

Install as Plugin

# Add the marketplace
/plugin marketplace add anthril/official-claude-plugins

# Install individual plugins
/plugin install data-analysis@anthril-claude-plugins
/plugin install knowledge-engineering@anthril-claude-plugins
/plugin install business-economics@anthril-claude-plugins
/plugin install package-manager@anthril-claude-plugins
/plugin install plan-completion-audit@anthril-claude-plugins
/plugin install skillops@anthril-claude-plugins
/plugin install brand-manager@anthril-claude-plugins
/plugin install software-development@anthril-claude-plugins
/plugin install ppc-manager@anthril-claude-plugins
/plugin install database-design@anthril-claude-plugins
/plugin install devops@anthril-claude-plugins

Install a Single Skill

# Copy one skill to your personal skills directory
cp -r plugins/data-analysis/skills/knowledge-graph-builder ~/.claude/skills/

Test Locally

# Load the full marketplace for development
claude --plugin-dir .

# Load a single plugin
claude --plugin-dir ./plugins/data-analysis

# List available skills
/skills

# Run a skill
/knowledge-graph-builder Build a knowledge graph for a consulting firm

Updating

Claude Code does not auto-refresh marketplaces — it reads from a local cache (~/.claude/plugins/marketplaces/<name>/) that is only re-fetched on demand. If a /plugin view shows you on the latest version when a newer release exists, the cache is stale.

To pick up a new release:

# 1. Re-fetch the marketplace clone (pulls the latest commit)
/plugin marketplace update anthril-claude-plugins

# 2. Update one or more installed plugins
/plugin update software-development@anthril-claude-plugins

The first command advances the cached marketplace's git HEAD; the second installs the new version into ~/.claude/plugins/cache/anthril-claude-plugins/<plugin>/<version>/ and rewrites the entry in installed_plugins.json.

See CHANGELOG.md for what is in each release before updating.

Skill Features

Every skill in this library includes:

  • YAML frontmatter — name, description (<250 chars), argument-hint, allowed-tools, effort
  • $ARGUMENTS — Accept user input directly (e.g., /skill-name my business description)
  • ultrathink — Extended thinking enabled for complex analytical skills
  • Output templates — Structured output format with section headers
  • Example outputs — Realistic completed examples with Australian business context
  • Utility scripts — Python/Bash helpers for common operations

Select skills also include:

  • context: fork — Research-heavy skills run in isolated subagent context
  • paths — Auto-activation when working with matching file patterns
  • reference.md — Dense reference material (SQL templates, scoring rubrics, lookup tables) extracted to keep SKILL.md under 500 lines
  • Dynamic context injection — Shell commands that inject project state before the skill runs
  • Parallel sub-agents — Independent audit targets (schemas, workflows, modules, Dockerfiles, charts, ecosystems) are audited in parallel for large-repo throughput

Creating New Skills

Use the built-in skill creator:

/skill-creator customer-churn-predictor — predict churn risk from behavioural signals

Or follow the conventions in .claude/CLAUDE.md to create skills manually.

Skill Development Checklist

  • SKILL.md has valid YAML frontmatter with name, description, effort

  • effort field set appropriately (medium, high, or max)
  • paths field set if skill should auto-activate on file patterns
  • templates/ directory has at least one output template
  • examples/ directory has at least one example output
  • Dense reference material is in reference.md, not SKILL.md
  • Plugin version in plugin.json matches marketplace entry (run node scripts/check-versions.mjs)
  • Tested locally with claude --plugin-dir .

Contributing

  1. Fork the repository
  2. Create a new skill using /skill-creator
