Scaffold a new PHP library for the tiny-blocks ecosystem, or restore a single canonical config/repository file (composer.json, phpcs.xml, phpunit.xml, phpstan.neon.dist, infection.json.dist, .editorconfig, .gitattributes, .gitignore, Makefile, the CI workflow, SECURITY.md, the issue templates, the PR template) to its standard shape. Use this skill whenever the user asks to create, bootstrap, set up, or initialize a new tiny-blocks library, to add the standard config/tooling files to a repository, or to fix/regenerate any of those files to match the ecosystem standard, even if they only mention one file by name. This skill owns the canonical bodies of those files. Do not hand-write them from memory.
Generate a git commit message in the tiny-blocks Conventional Commits format (type-prefixed, imperative, capitalized, period-terminated, no scopes). Use this skill whenever the user asks you to write, draft, suggest, or fix a commit message, or whenever you are about to propose commit text for staged changes, even if they do not say the words "conventional commits". Commit messages are produced on request only and are never generated automatically as part of another task.
Discover and reuse an existing tiny-blocks library as a dependency instead of writing or keeping hand-written code. Use this skill in two moments: before implementing a capability from scratch or adding a dependency from outside the ecosystem, and when reviewing or refactoring existing code, to catch where a tiny-blocks package now covers something already written by hand. It checks the catalog of published tiny-blocks packages for a candidate, adds the match with composer, and reads the installed library's own README and public API to use it correctly. Trigger on any request to implement, add, build, review, simplify, or refactor where an existing building block (collections, value objects, money, time, http, mapping, logging, identifiers, and similar) might apply.
