Proven architecture patterns for robot software — behavior trees, FSMs, HALs, safety systems — with working code examples.

Turns feature requests into detailed, sequential implementation plans with file-level tasks and dependencies.

A skill that guides Claude to copy, move, and extract functions or classes between files with line-level precision.

A read-only skill that reports file metadata and statistics — size, modification time, line counts, function/class counts — without touching your files.

A static-analysis skill that uses abstract interpretation to summarize execution paths, variable ranges, and loop invariants without running the code.

Defines how the TestDriver agent reviews pull requests, onboards from issues, and responds to @mentions on GitHub.

A reference skill for configuring and debugging TestDriver's screenshot-based cache to speed up AI test runs.
