Craft + UX review of a user-facing change before merge — visual hierarchy, accessibility floor, and AI-slop tells, against an approval bar. Use in the VERIFY phase for any change that touched a UI surface, parallel to /security-review. Judges by default; reports severity-tagged findings, does not rebuild unless asked.
Skill Claude CodeCodex
Produce a product/UX/UI design brief before building a user-facing surface. Use in the PLAN phase after /plan, alongside /architect, when a change has a UI (dashboard, app, marketing page, mobile screen). Routes to the right craft rubric, overlays the accessibility/UX floor, and emits a brief that guides…
Skill Claude CodeCodex
Discovery phase — the entry point ABOVE /spec, for when the user has a vague intent but doesn't yet know the shape of the answer or what's even possible ("make this better", "what could I build with X"). Turns vague intent into a framed problem + ONE chosen direction that /spec can consume. Divergent→convergent…
Skill Claude CodeCodex
Checkpoint a change against its spec's acceptance criteria — run the machine-checks, adjudicate the prose ones, and gate ship until every criterion passes. Opt-in; not wired into the default pipeline. Use late in Verify, alongside /test and /verify.
Skill Claude CodeCodex
Turn a repeatable workflow observed this session into a PROPOSED reusable skill — draft it, evaluate it against the rubric, and stage it for your approval. Never writes into skills/. Opt-in; not wired into the default pipeline. Use when a Stop candidate appears or a workflow felt worth keeping.
Skill Claude CodeCodex
Bug-fix fast lane — the entry point for fixing something already broken (a red test, a prod error, a reported defect), not building a new feature. Does the bug-specific part — reproduce as a failing test, find the root cause, write a minimal fix-plan — then hands off to the existing pipeline (/implement → /review →…
Skill Claude CodeCodex
Orchestrate the entire IMPLEMENT phase — test-driven implementation of the approved plan, resolving build/type errors as they arise. Use after /harness-plan. Sequences /implement and /build-fix, delegates to subagents, and halts if reality diverges from the plan.
Skill Claude CodeCodex
Orchestrate the MAINTAIN phase — understand the codebase (if unfamiliar) then safely remove dead code, duplication, and tech debt. Use after shipping or on an accumulating codebase. Sequences /onboard and /refactor-clean, delegates to the harness-claude:refactor-cleaner agent, and halts before ambiguous deletions.
Skill Claude CodeCodex
Orchestrate the entire PLAN phase in one command — spec, research, plan, plan-check, and (if warranted) architecture. Use at the start of any non-trivial feature/change. Sequences the atomic skills, delegates to subagents, and pauses for your input at each decision gate.
Skill Claude CodeCodex
Orchestrate the entire VERIFY phase — code review, security review, tests, run-the-app verification, and ship-prep. Use after /harness-implement. Sequences the Verify skills, runs reviewers in parallel when sensible, halts on Critical/High findings, and stops at the git boundary.
Skill Claude CodeCodex
Run the FULL SDLC pipeline end-to-end — Plan → Implement → Verify → Maintain — with a checkpoint between every phase. Use for a complete feature from a one-line idea to merge-ready. Chains the four phase orchestrators; you approve each phase boundary.
Skill Claude CodeCodex
Take the target repo's health pulse on demand — run its test/lint/typecheck (and any extra) checks and emit one pass/fail summary. Auto-detects the repo's checks (package.json scripts or Makefile) with explicit --cmd override. Opt-in; not wired into the default pipeline. Output streams live but is never captured…
Skill Claude CodeCodex
Execute a plan via test-driven development — write tests first, then minimal code, phase by phase. Use after /plan (and /architect if needed) to write the actual feature. Delegates to the harness-claude:tdd-guide agent.
Skill Claude CodeCodex
Build the minimum that actually works — question whether the task needs to exist (YAGNI), reach for stdlib before custom code, native platform features before dependencies, one line before fifty. A persistent generation-reduction bias for the Implement phase. Use when the user says "be lazy", "lazy mode", "minimal"…
Skill Claude CodeCodex
Feedback step that closes the loop from production back into the harness — take a signal you BRING to it (a pasted stack trace, log snippet, error text, or an issue/monitoring URL), triage it into a located, reproducible failure, and route it into the existing /fix lane. Bring-a-signal only — no polling, no…
Skill Claude CodeCodex
Build a fast mental map of an unfamiliar codebase — structure, entry points, data flow, conventions, and where things live. Use when starting work in a new/unfamiliar repo, or to refresh context after time away. Supports maintenance.
Skill Claude CodeCodex
Supervise a long-running, unattended agent run — an autonomous loop or a scheduled wake-up — that self-checkpoints against the repo's eval skills so it can't silently drift. Rides the platform's /loop + /schedule; adds halting guardrails (iteration cap, wall-clock budget, drift) and durable run state. Opt-in; not…
Skill Claude CodeCodex
Decompose a multi-file task, fan out to parallel workers in dependency-ordered waves, and reconcile their results — with a one-writer-per-file guarantee. The third orchestration mode (parallel fan-out) alongside sequential and iterative-retrieval. Rides the platform Workflow tool as the engine; the skill is the lead …
Skill Claude CodeCodex
Adversarially review a plan against its spec before implementation — check that every acceptance criterion is covered, no scope crept in, and parallel tasks have disjoint write-sets. Use after /plan, before /implement. Read-only gate; delegates to the harness-claude:planner agent in a check pass. Non-blocking except…
Skill Claude CodeCodex
Produce a phased, risk-assessed implementation plan from a spec. Use after /spec and /research, before writing code. Delegates to the harness-claude:planner agent for non-trivial work.
Skill Claude CodeCodex
Remove dead code, duplication, and tech debt safely during the Maintain phase. Use after shipping, or when a codebase has accumulated cruft. Delegates to the harness-claude:refactor-cleaner agent. Behavior-preserving only.
Skill Claude CodeCodex
Reuse-first research before writing new code. Search existing libraries, registries, and codebases for something that already solves the problem. Use after /spec, before /plan. Mandatory for non-trivial implementation.
Skill Claude CodeCodex
Load the most recent session file and re-establish context at the start of a new session. Use when continuing multi-session work. Pairs with /save-session.
Skill Claude CodeCodex
Review changed code for quality, correctness, and maintainability before merge. Use immediately after implementing or modifying code. Delegates to the harness-claude:code-reviewer agent. First gate of the Verify phase.
