Claude Skills by thermiteau

How to execute an implementation plan step-by-step. Covers the execution loop, verification discipline, failure handling, progress tracking, crash recovery, and acceptance criteria. Adapts behaviour based on whether the caller is solo (autonomous) or guided (human checkpoints). Used as a dependency from workflow skills.

Defines what Claude Code must refuse to do without explicit authorisation. Covers infrastructure, auth, destructive git, and production systems. Applied automatically to all workflows.

How to stack a PR on top of an unmerged sibling branch, and how to retarget it to the repo's default branch once the sibling merges. Prevents orphan-merge incidents when a dependent story is ready before its parent.

Use when encountering any bug, test failure, or unexpected behaviour during implementation. Requires root cause investigation before proposing fixes.
