Reusable Codex skills for Story-Driven Development
This repository also configures its own agents. See what sdd-skills tells them →
Skill Codex
Create, update, or assess Architecture Decision Records for SDD projects. Use when the user invokes /sdd-adr, asks to draft an ADR, asks whether a technical decision needs an ADR, wants to record architecture options and tradeoffs, or when another SDD skill reaches a durable architecture, data, dependency…
Skill Codex
Deliver exactly one next-ready or explicitly requested outcome from a planned or in-progress v2 SDD Change. Protect unrelated work, follow repository guidance, implement and freshly verify the outcome, obtain independent Review, reconcile Epic truth when required, create one content-identical local commit, record it…
Skill Codex
Capture, plan, or revise one workspace-central SDD Change. Use when the user wants to preserve a desired outcome, create a Change, continue a proposed Change into implementation-ready outcomes, or revise remaining work after new evidence changes the plan.
Skill Codex
Audit the health of an entire application repository or a selected codebase area using independent specialist reviewers and an evidence-validated synthesis. Use when the user invokes /sdd-code-audit, asks for a comprehensive codebase review beyond one Change, wants an application or subsystem assessed for code…
Skill Codex
Plan or revise experience-design readiness for a UI-bearing SDD Change. Use /sdd-design --plan after Change planning to converge unresolved flow, responsive, component/state, accessibility, or visual direction before implementation, and /sdd-design --revise when candidate-bound implementation, review, comparison, or…
Skill Codex
Audit a SDD Epic end to end against current implementation reality with subagent delegation, mandatory full reverse traceability, systematic Requirement/Scenario testing, Epic coherence review, missing Story/Requirement/Scenario detection, Story label/reference traceability checks, Change-status and evidence drift…
Skill Codex
Create or resume a durable synthesized record for any substantial discussion the user wants preserved beyond chat. Use when the user invokes /sdd-explore or asks to discuss, think through, investigate, compare, brainstorm, or reason about something with a lasting record—such as technical feasibility, marketing…
Skill Codex
Create and apply one lightweight v2 SDD Change in a tracked interactive session. Use for small UI tweaks, narrow defects, polish, or minor behavior refinements that deserve durable intent, one outcome, independent Review, Epic reconciliation when needed, and one local commit.
Skill Codex
Run a conservative SDD orphan and reverse-traceability audit for an application repo, one Epic, or a changed surface. Use when the user invokes /sdd-orphan-audit, asks to find orphaned tests, unused files, stale functions, dead code candidates, missing Epic references, stale Implemented By or Verified By evidence…
Skill Codex
Use when the user invokes /sdd-pr or asks to open, manage, review, or steward a pull request for SDD-backed work according to project branch and review policy. Creates a PR when one does not exist, and on later activations checks comments, requested changes, status checks, and review threads; routes accepted code…
Skill Codex
Create, draft, periodically revisit, or reason about private project planning Product Briefs/PRDs and Feature/Capability Briefs for SDD application projects through a lightweight grill-me style product interview. Use when the user invokes /sdd-prd, wants a starting point for product direction, refines product scope…
Skill Codex
Prepare coordinated SDD release handoffs to project-defined production targets. Use when the user invokes /sdd-release, asks to release, promote, cut a release, run release checks, review a changelog, prepare required release communication or version metadata, suggest a version increment, or open production PRs. Runs…
Skill Codex
Independently review one exact v2 SDD outcome candidate or the final Change candidate. Record five universal gates, concrete risk-triggered checks, separate Spec Adherence and Implementation Quality judgments, honest gaps, and integration readiness in the one central review.md.
Skill Codex
Produce a concise read-only re-entry brief for an SDD Space. Use when the user invokes /sdd-space-status or /space-status, says it has been a while since working on an app, asks where work left off, what is active or blocked, which files matter, or what to do next. Wraps the deterministic sdd status --json inventory…
Skill Codex
Create or update one candidate-bound changelog, release-note, changeset, or equivalent entry for a completed SDD Change or clearly scoped manual change. Use after review and Epic reconciliation, when the user asks to document what changed, add release notes, update a changelog, prepare one Change's release…
Skill Codex
Reconcile repository-owned SDD Epic, Story, Requirement, Scenario, implementation-map, gap, and verification-map truth against one exact candidate. Use when accepted behavior, Story completion, or a consumed contract/gap changed, or when current Epic truth is demonstrably stale.
Skill Codex
Gather the minimum planning, repository, decision, behavior, implementation, test, and Git context required before an SDD exploration, ADR, or Change makes claims. Use from sdd-explore, sdd-adr, or sdd-change with an action (exploration, adr, or change) and a focused question. Read-only, same-session, and…
