It sits in Development, covering Code quality. The repository describes itself as: A curated marketplace of Claude Code plugins that embody the principles of ethical and professional software development.

When your agent uses it

  • Configuring Ameba rules and settings for Crystal projects including .ameba.yml setup
  • Rule management
  • Severity levels
  • Code quality enforcement

Example prompts

  • “/ameba-configuration”

Requirements

  • Pre-approved tools (allowed-tools): Bash, Read

Workflow steps

12 steps, taken from the first numbered list in SKILL.md.

  1. Start with generated config - Run ameba --gen-config to see all available rules and their defaults
  2. Use version control - Commit .ameba.yml so team members share the same configuration
  3. Enable incrementally - Start permissive, gradually enable more rules as team adapts
  4. Set appropriate severities - Use Error for blocking issues, Warning for important, Convention for style
  5. Document exceptions - Add comments explaining why specific rules are disabled or configured differently
  6. Scope exclusions narrowly - Exclude specific files/directories rather than disabling rules globally
  7. Use inline disables sparingly - Prefer fixing issues over disabling rules; when necessary, be specific
  8. Review generated config - Don't blindly use default config; review and customize for your project
  9. Separate concerns - Use different severity levels for different types of issues (bugs vs style)
  10. Test configuration changes - Run ameba locally before committing configuration changes
  11. Keep config maintainable - Group related rules together and use comments to explain sections
  12. Align with team standards - Configuration should reflect team consensus, not individual preferences

What it can do on your machine

Read from SKILL.md and the folder at commit 19caa51. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash
    • Read

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml, crystal and bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • crystal-ameba.github.io
    • github.com
    • crystal-lang.org

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ameba Configuration loads about 4.2k tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 656 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~45
When it runs · the whole SKILL.md, loaded when a task matches
~4.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Bash, Read

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 656 words (~4,231 tokens).

“Configure Ameba, the static code analysis tool for Crystal, to enforce consistent code style and catch code smells in your Crystal projects.”
