Formal evaluation framework for Claude Code sessions implementing eval-driven development (EDD) principles

Use when the user asks to plan a LARGE feature spanning multiple sessions or phases — produces an epic under the `tasks` role with dependency-ordered phases, atomic tasks and per-phase status. Use plan for single-session tasks, not for roadmaps.

Add TypeScript strict-mode code-style rules to AGENTS.md. The rule text ships inside this skill, so write it from here, not from memory. Use when the user asks for strict-mode style rules. Not for Deno projects (use setup-agent-code-style-deno).

Creates interactive HTML teaching materials with clickable state diagrams. Use when the user asks to produce an explorable tutorial artifact, not to answer a question.

Collect GitHub, CodeRabbit, Codex review, and CI findings across named PRs; confirm issues against current code and fix them with evidence. Use when the user requests PR review-thread sweeps, CI remediation, or until-green monitoring, merge, and cleanup.

Guide for creating persistent AI rules — coding standards, project conventions, file-specific patterns. Use when users want to create a rule, set up conventions, or ask where rules go. Works across IDEs (Cursor, Claude Code, OpenCode).

Run structured AI code review as an advisory closeout gate for local diffs, PR branches, or commits when the user asks for autoreview, Codex review, second-model review, or pre-ship validation.

Implement approved Harness Engineering work. Use when a plan, todo list, or tiny spec needs traceable delivery and validation.

Write Harness Engineering specs before planning. Use when a feature, QA report, Linear issue, or UI source needs a clear WHAT contract.
