Software Development Skills

Apply clippy-aligned Rust practices when writing or editing Rust code (.rs). Covers procedural flow, clippy-driven clarity improvements, minimal imports, Result/Option idioms, fallible builders with project error types, string prefix/suffix handling, borrowing clarity, iteration style, string building, and function signature grouping.

Refresh a local git repo back to a clean current default branch: fetch/prune, detect the remote HEAD, fast-forward main/master by --ff-only, delete merged local branches, and offer gated cleanup for upstream-gone, squash-merged, stale, or force-delete branch pruning. Use when the user asks to clean up branches, refresh main, refresh master, delete merged branches, get back to a clean main, prune stale local branches, or tidy local branches after merged PRs. Invoke only on that explicit request in the current turn; noticing stale or merged branches during other work leaves the cleanup to the user.

Hub and source of truth for the repo-root guardrail documents (CHARTER.md, ARCHITECTURE.md, TESTING.md, SECURITY.md) that keep AI agents anchored to human intent while a project evolves within its declared boundaries. Explains the doc set, the authority hierarchy, the shared format, and how skills consult the docs, suggests which guardrails fit a repository, and drafts one only on explicit user request. Use when the user asks what guardrail docs are, which ones a repo should adopt, to suggest, bootstrap, set up, or draft a charter, architecture, testing, or security doc, how guardrail docs rank against each other or against CLAUDE.md, AGENTS.md, or GEMINI.md, or how agents consult and enforce these docs. For auditing existing guardrail docs against each other and the codebase, route to guardrailaudit.

Autonomously drive one task from open or checked to ready by looping through taskcheck as the only readiness gate, reviewer repair proposals, verifier-approved intent-safe edits, and re-checks. Use when a user asks to auto-fix readiness issues, make a task ready, or run an autonomous readiness loop without implementing the task.

Select and rank eligible live tasks from the project backlog. Use when the user asks what task to work on next, asks Codex to pick or prioritize backlog work, rank open tasks, choose from tasks/, or recommend the next task/action without editing task files.
