Interactive onboarding walkthrough for teams introducing claude-crap on an existing codebase. Use this skill whenever the user asks "how do I install claude-crap on my project", "we're adopting claude-crap for our team", "how should I roll claude-crap out", "what strictness mode should I pick", "we have a lot of legacy code, can we ease into this gradually", "our project has a bunch of existing errors, how do I avoid getting blocked", or is otherwise looking for guidance on gradual rollout strategy instead of just dropping a strict quality gate on a messy codebase. The skill asks a short three-question assessment about test coverage, existing findings, and appetite for hard enforcement, recommends one of three strictness modes (advisory / warn / strict), and emits a copy-pasteable .claude-crap.json snippet for the workspace root so the team can commit the policy in a single step.
Run tree-sitter AST analysis on a source file using claude-crap's deterministic engine and report per-function cyclomatic complexity plus physical and logical lines of code. Use this skill whenever the user asks "what's the complexity of this file", "how complex is foo.ts", "show me cyclomatic complexity per function", "analyze this file's structure", "which functions in this file are too complex", "where should I refactor first in this module", or needs to pick candidates for refactoring based on complexity. Also use this skill proactively when a file feels "big" and you want a ranked list of hot-spot functions before proposing a refactor plan — the tree-sitter engine gives exact numbers instead of eyeball estimates. Supports TypeScript, JavaScript, Python, Java, and C#; the language is detected automatically from the file extension. Takes a single file path as the argument after the skill name.
Check whether a production source file has an accompanying characterization test using claude-crap's deterministic test-harness resolver. Use this skill whenever the user asks "is this file tested", "does foo.ts have a test", "where's the test for bar.py", "check test coverage for this file", "do I have a test harness for src/baz.java", or is about to modify a source file and wants to know if the CLAUDE.md Golden Rule test prerequisite is already satisfied. Use it proactively at the start of any work on a .ts / .tsx / .js / .jsx / .mjs / .cjs / .py / .java / .cs file to verify a characterization test exists — this is required by CLAUDE.md and claude-crap's PostToolUse hook will flag the violation later if you skip the check. The skill takes a single file-path argument after the skill name.
Run claude-crap's deterministic project quality gate and display the A..E letter grade across Maintainability, Reliability, Security, and Overall. Use this skill whenever the user asks "how's the code quality", "what's my CRAP index", "is this project shippable", "show me the technical debt ratio", "run the quality gate", "score the project", or wants a one-glance read on whether the current workspace passes its policy ceiling. Also use this skill proactively at the start of a refactoring session or before a release to establish a quality baseline, and after a substantial refactor to verify the grade has not regressed. Do NOT use it for incident debugging or per-file analysis — for a single file, reach for /claude-crap:analyze instead.
