Creates Architecture Decision Records (ADRs) in Michael Nygard's canonical format. Auto-detects the project's ADR directory on every run (no persisted configuration), generates sequential numbering, and operates in STANDALONE mode (questions to the user) or INVOKED mode (receives pre-filled context from another skill…

Rigorous TWO-AXIS code reviewer. Standards - does the code follow THE PROJECT's rules guide (docs/sdd/09-review-rules.md)? Spec - did the code fulfill its originating spec/PRD (did it do what was asked)? The two are measured separately and reported side by side; a reproval is always anchored in a textual citation (a…

Discipline for diagnosing hard bugs and performance regressions — requires a reproduction loop that goes RED on the bug BEFORE any hypothesis (signal before theory). Finds the root cause and stops; the non-trivial fix is handed to spec-create. Use when the user asks to diagnose or debug something, or reports something…

Records a feature's AI-First evidence - prompts used, reviews (what was corrected or rejected from the AI) and delegated skills - inside specs/ /ai/, and maintains a global index at ai/index.md. Made for AI-First challenges and projects that require the ai/ folder (skills.md, prompts.md, reviews.md - or the file names…

Standardizes Java unit tests with JUnit 5 following 13 strict rules of quality, performance and clarity (no inheritance, should+camelCase naming, no comments, ParameterizedTest, self-contained scope, AAA, boundary+MC/DC depth, Sonar-safe assertThatThrownBy). Operates in CREATION mode (generate new tests), REFACTOR…

Implements the full SDD flow to EVOLVE a project already initialized by spec-init - receives a feature, bugfix or refactor brief, generates the PRD, technical spec and task plan with blocking human checkpoints, and after approval delegates the implementation to the spec-execute skill and, on closing, records the…
Skill Claude CodeCodex
Executes the approved plan of an SDD feature (specs/ /04-plan.md) task by task, respecting the dependency DAG and the P0/P1/P2 priorities, applying the development premises (security, performance, resource usage, clarity) and active context control (tiers, hand-off). Invoked by spec-create after plan approval, or…

Initializes a project's SDD (Specification-Driven Development) structure. On an EXISTING project, runs a phased deep analysis with chunking and generates /docs/sdd/ (00-overview to 08-glossary), CONSTITUTION.md and the review rules guide. On an EMPTY project (greenfield), conducts a guided interview about…
