Skill Claude CodeCodex
Architecture design and analysis – review, decomposition, trade-off analysis, ADRs, CUPID/DDD guidance, fitness functions, strategic design, event storming. Seven modes, runnable singly or chained (--mode review,fitness). Trigger on 'architecture review', 'bounded context', 'trade-off', 'write an ADR'.
Skill Claude CodeCodex
Discovery & Ideation for requirements at feature or product scope – systematic discovery of gaps, edge cases, scope boundaries, and alternatives the user hadn't considered. Trigger on 'clarify requirements', 'what are the requirements', 'product vision'.
Skill Claude CodeCodex
End-to-end browser testing for web apps – discover journeys, run interactive tests, validate responsive behavior. Trigger on 'test the app end to end', 'e2e test', 'browser test'.
Skill Claude CodeCodex
Create high-visual-quality Excalidraw diagrams where structure and design do the explaining. Trigger on 'draw this architecture', 'workflow diagram', 'create an Excalidraw diagram'.
Skill Claude CodeCodex
Execute a fully-specced implementation plan bundle (every story already has a FIS) – fixed per-story pipeline plus a final gap review. Supports Agent Teams (--team) and per-story worktree isolation (--worktree). Trigger on 'execute this plan', 'run the plan', 'run as team'.
Skill Claude CodeCodex
Implement code from an existing spec – a Feature Implementation Specification (FIS). Trigger on 'execute this spec', 'implement this FIS', 'build from spec'.
Skill Claude CodeCodex
Explain what changed in a PR, branch, or changeset as a narrative Changeset Walkthrough, rendered as an interactive HTML tour. Comprehension only – for findings or a verdict use the andthen:review skill. Trigger on 'explain this PR', 'what changed on this branch', 'changeset walkthrough'.
Skill Claude CodeCodex
Compact the current conversation into a handoff document a fresh agent can resume from – before /clear, when running low on context, or at a session boundary. Trigger on 'handoff', 'wrap up for resume', 'fresh start'.
Skill Claude CodeCodex
Set up the AndThen workflow structure – new projects, partial setups, and brownfield codebases. Trigger on 'set up AndThen', 'initialize the workflow', 'bootstrap AndThen'.
Skill Claude CodeCodex
Triage incoming issue-tracker items – label, categorize, and route untriaged bugs and enhancements toward implementation or human decision. Trigger on 'triage the backlog', 'process incoming issues', 'label new issues'. Not for debugging a failure – that is the andthen:triage skill.
Skill Claude CodeCodex
Analyze an existing codebase into structured documentation and discovered implicit requirements, optionally emitting a typed Architecture Model (--model) for atlas rendering. Trigger on 'map codebase', 'understand this codebase', 'what does this repo do', 'generate an architecture model', 'refresh the architecture…
Skill Claude CodeCodex
Internal squash-merge of one story worktree branch into the integration branch, guarded, committing with the load-bearing Squashed-story: trailer. Invoked per story by the andthen:exec-plan skill's worktree merge flow; not user-invocable.
Skill Claude CodeCodex
First-stop router – inspects project state (init'd? greenfield? brownfield? mid-flow?) and routes to the right AndThen skill. Trigger on 'where do I start', 'now what', "I'm stuck", 'is this a PRD or a spec'.
Skill Claude CodeCodex
Deterministic operations – update shared/local state, plan status, story ownership, FIS checkboxes, standardized commits. Trigger on 'mark story done', 'claim story', 'update FIS checkboxes', 'progress summary'.
Skill Claude CodeCodex
Produce the full plan bundle (plan.json + a FIS per story) from a local prd.md, --issue , or a GitHub issue URL; redirects to the andthen:prd skill when no PRD source resolves. Trigger on 'create a plan', 'break this into stories', 'spec all stories'.
Skill Claude CodeCodex
Create a Product Requirements Document from clarified requirements, a draft, an inline description, a file, a URL, or a GitHub issue, then run fresh-context doc self-review. Trigger on 'create a PRD', 'write a PRD', 'PRD from clarify output'.
Skill Claude CodeCodex
Drive a FIS or plan bundle to zero open blocking decisions before unattended execution – interviews the user per decision, settles open ADRs, emits a machine-stable READY/DEFERRED/BLOCKED verdict. Authoring belongs to the andthen:spec skill or andthen:prd skill; execution belongs to the andthen:exec-spec skill or…
Skill Claude CodeCodex
Quick implementation path for small features or fixes, with verification. Bypasses the FIS workflow – larger features take the andthen:clarify → andthen:spec → andthen:exec-spec skill chain. Trigger on 'quick fix this', 'make this small change'.
Skill Claude CodeCodex
Quick critic review of recent changes in fresh context – a mid-conversation sanity check before moving on. Trigger on 'quick review this', 'sanity-check this', 'critic this'.
Skill Claude CodeCodex
Deprecated alias. Routes to the andthen:simplify-code skill for behavior-preserving code simplification. Do not invoke directly in new work.
Skill Claude CodeCodex
Implement actionable findings from a review report – minimal, guideline-aligned fixes across code, specs, plans, PRDs, and documentation – then re-validate and update plan/FIS status. Trigger on 'address these review findings', 'fix review comments', 'remediate findings'.
Skill Claude CodeCodex
The default review skill – code, docs, gap, security, PR, adversarial/red-team, and multi-reviewer council reviews. Proves coverage before verdict, routes findings into Fix/Note, can remediate or visualize the report. Trigger on 'review this', 'audit this', 'does this match the spec', 'security review'.
Skill Claude CodeCodex
Simplify and refine code for clarity, reuse, quality, efficiency, and leanness (YAGNI) – reduce complexity and over-engineering while preserving exact behavior. Trigger on 'simplify this code', 'clean this up', 'refactor this', 'remove over-engineering'.
