Included Skills9

composeskills/compose/SKILL.md

Use when work is about to be delegated to another model or agent — Codex, a Claude subagent, or similar — and needs a prompt or agent instructions; produces a lean, outcome-first delegate prompt with a dated model and effort choice.

grillingskills/grilling/SKILL.md

Use when the owner explicitly asks to grill a plan or decision, conduct a decision interview, or invokes $grilling. Do not select for routine implementation, fixes, reviews, or explanations merely because they involve design choices.

handoffskills/handoff/SKILL.md

Use when work must continue in a fresh session and the next agent needs context it cannot recover from durable artifacts — creates one compact, privacy-safe Markdown handoff in the operating system's temporary directory.

improve-codebase-architectureskills/improve-codebase-architecture/SKILL.md

Use when a codebase feels harder to change than it should and the friction needs locating — scans git-history hot spots and deletion-test candidates into a visual HTML report, then grills through whichever candidate the owner picks.

limitsskills/limits/SKILL.md

Use when a repository adopts or enforces the three-sources-of-truth model, where git holds the past, code holds the present, and GOALS.md holds the future, with every limit a number checked in CI. Ships the checker and templates for GOALS.md, AGENTS.md, and the CI workflow.

limits-coreskills/limits-core/SKILL.md

Use when adopting or reviewing a persistent agent working kernel with bounded active context, deferred work and recoverable history. Reuses existing memory files and checks size at session entry or after context compaction. Does not run maintenance on every turn or enforce code-repository limits.

prototypeskills/prototype/SKILL.md

Use when a design question — does this state model feel right, what should this UI look like — needs a real answer before committing to a build; a throwaway prototype on a worktree branch, and only the validated decision lands.

sliceskills/slice/SKILL.md

Use when an approved goal, phase, or parent issue needs cutting into small, agent-ready GitHub issues.

watchskills/watch/SKILL.md

Use when an open PR needs babysitting through the Codex review loop — waits for each verdict, fixes blocking findings within the caller's round budget, and proceeds through CI and authorized merge when none remain.
