Add a Playwright end-to-end test for a user-facing flow — sign-in, form submit, multi-step wizard, payment, navigation, etc. Detects existing Playwright setup and inherits its config (baseURL, projects, fixtures, auth state); installs Playwright via the…
Sibling to add-skeleton-loaders. After data fetching is wired in a route or component, verify and auto-fix the two non-loading states most often forgotten — empty (the request succeeded but returned zero items / null) and error (the request failed). Empty…
End-to-end workflow for planning and shipping a new feature in an existing codebase. Phases — clarify → explore → design → mandatory plan-approval gate → implement (subagent fan-out where useful) → verify → gated reviews (code + duplication always; security…
Scaffold a form in this TanStack Start app following the project's conventions — a single zod schema reused on the client (react-hook-form resolver) AND on the server function (input validation), shadcn `<Form>`/`<FormField>` primitives for the UI, a server…
After a bug fix lands (or is staged), generate a regression test that fails on the pre-fix code and passes on the post-fix code — pinning the bug so it can't silently return. Walks the agent through reproducing the failure first (against the pre-fix state via…
Generate a developer seed-data script for a feature — creates representative rows through the data-access layer (not raw SQL) so the seed respects schema, foreign keys, and any business invariants encoded in DA functions. Detects an existing `scripts/seed.ts`…
Verify that any new TanStack Start route — or any new data-fetching section added to an existing route — renders shadcn `<Skeleton />` placeholders matching the eventual layout while data is in flight. Auto-fix gaps inline before reporting done. Trigger…
Address every unresolved review comment on a GitHub pull request — locate the PR (current branch, PR URL, PR number, or issue number with linked PR), fetch both inline review comments and PR-level issue comments, then for each thread ground the fix in the…
Initialize or refresh a project for the AgentSystem plugin system by writing a concise table-of-contents of available AgentSystem skills into the project's agent-instruction file (CLAUDE.md and/or AGENTS.md). The TOC lists each skill's invoke command and…
Static accessibility audit of a route/component — checks keyboard reachability, screen-reader semantics (ARIA labels, label/input association, roles), and WCAG AA color contrast. Auto-fixes the mechanical gaps inline (icon-button labels, image alt, label…
Audit analytics event tracking across a route, feature, or the whole client surface — verifies that important user actions emit events, that event names match the project's existing taxonomy (snake_case vs camelCase, prefix conventions, verb tense), that…
Static performance audit of a route, page, server function, or module — finds N+1 query patterns, missing DB indexes for filtered/joined columns, oversized SELECT * fetches, blocking sequential awaits that could parallelize, unmemoized React hot-path…
Per-route SEO and social-share metadata audit — checks `<title>`, meta description, canonical URL, Open Graph tags (og:title, og:description, og:image, og:url, og:type), Twitter card tags, viewport, robots directives, and the presence of a sitemap and…
Whole-codebase tech-debt sweep. Orchestrates every available code-* audit/cleanup skill (duplication, type safety, data integrity, security, contracts, error boundaries, loading states, a11y, concurrency, client-bundle, observability, perf, simplify) across…
Bootstrap an empty directory into a runnable project from the AgentSystemLabs/launch-kit template — clones the template, strips its git history, runs setup (env file, install, docker compose), launches the dev server, and diagnoses missing prerequisites…
Pre-PR gauntlet — run the project's typecheck, linter, formatter, and test suite against the branch's diff vs. the base, plus a residue sweep for `console.log`, `.only` / `.skip`, debugger statements, leftover TODOs in changed files, dropped lockfiles, and…
Generate and review a Drizzle (or Prisma / Knex / raw SQL) migration safely — classifies the change as additive, mutating, or destructive; for mutating/destructive changes, splits into a multi-phase plan (deploy code that tolerates both shapes → migrate →…
Internal handoff target invoked by add-feature, modify-feature, and tweak-ui after UI mutation. Scoped, changed-files-only accessibility audit — a faster sibling to `audit-a11y` that runs automatically without producing whole-app noise. Catches icon buttons…
Internal handoff target invoked by add-feature, modify-feature, and code-enforce-layers when client-side code changes. Audits accidental client-bundle bloat and server-only leakage — server libraries (drizzle, prisma, fs, child_process, postmark, stripe-node,…
Internal handoff target invoked by add-feature, modify-feature, and fix-bug after mutations, background jobs, or webhook handlers change. Audits race conditions, retry-safety, and idempotency — double-click creating duplicate records (no submit lock, no…
Internal handoff target invoked by add-feature, modify-feature, and fix-bug after changes that cross the client/server boundary. Audits API/route/schema contracts for drift the type system can't catch — frontend reads field `x` while backend now returns `y`,…
Internal handoff target invoked by add-feature, modify-feature, code-add-migration, and code-realign whenever a change touches migrations, schema, persistence, imports, deletes, or background jobs. Audits data-integrity risks the type system can't catch — NOT…
Internal handoff target invoked by add-feature, modify-feature, code-realign, and other mutation skills as a post-step audit of recently-edited TypeScript/TSX files. Detects parallel-enum drift the type system can't catch — parallel-array drift, repeated…
Internal handoff target invoked by add-feature, modify-feature, and fix-bug after a feature lands to audit failure paths. Catches the failure-mode gaps that produce blank screens and silent corruption — promise rejections that leak to a blank screen (no…
Internal handoff target invoked by add-feature and modify-feature after async UI changes. Audits async-state UX consistency complementary to add-skeleton-loaders (which adds skeletons for new routes) and add-empty-error-states (which covers empty/error).…
Internal handoff target invoked by add-feature, modify-feature, and fix-bug after critical-path changes. Read-only audit of observability coverage — sibling to `code-add-observability` (which inserts logs); this skill REPORTS gaps without auto-instrumenting.…
Final pre-publish handoff invoked by commit-push-and-make-pr, commit-and-push, open-pr, and release skills. Summarizes what changed on the branch and what could break in production — public API surface changes, persistence shape changes,…
Internal handoff target invoked by fix-bug when a failure crosses process or runtime boundaries — Electron vs Node, browser vs server, dev server vs packaged app, worker vs main thread, CLI vs app runtime, native modules, ABI mismatch, preload script, IPC…
Internal handoff target invoked by add-feature, modify-feature, and other mutation skills when working in TanStack Start projects to enforce the layered architecture — routes/components/hooks/queries call server functions in `src/fn/`, which call use cases or…
Tighten TypeScript safety in changed files — strip `any`, dangerous `as` casts, `@ts-ignore`/`@ts-expect-error`, and missing return types on exported APIs; add zod (or existing project validator) at boundary surfaces (HTTP/server-fn input, IPC, queue…
Internal handoff target invoked by add-feature, modify-feature, or fix-bug when they detect a domain-model rename — an enum/state/vocabulary change with persisted values that requires a tracked data migration. Users typically don't invoke this directly; the…
Internal handoff target invoked as a post-step by add-feature, modify-feature, fix-bug, fix-pr-tests, address-pr-comments, remove-feature, code-realign, and reorganize-files to clean up freshly-changed code. Reviews the git diff for DRY violations, duplicate…
Internal handoff target invoked as Phase 8 of add-feature and as the test step for modify-feature and code-realign — and any time a feature lands without a test step. Stack-agnostic phased workflow for adding or expanding an automated test suite for a chosen…
Run the agentsystem-core commit skill to produce grouped commits from the working tree, then push the current branch to its remote (setting upstream with -u when missing). No-op when there is nothing to commit. Never force-pushes. Use when the user says…
One-shot "commits + branch push + PR" workflow — split a dirty working tree into logically grouped commits, create/push the branch if needed, and open a GitHub pull request with a senior-engineer-quality title, high-level (non-technical) description,…
One-shot ship workflow on `main` — delegate to the `commit-and-push` skill (group commits, push branch), then delegate to the `release` skill with a default minor version bump, then push the new tag to origin. Use when the user says "commit push and release",…
Split a working tree with many changed files into multiple logically-grouped commits instead of one mega-commit. Groups files by relatedness (shared module, feature slice, layer, test+impl pairs, rename+edit pairs) and orders commits so each one builds on its…
Create a GitHub issue from a short user description, auto-classify it with type + area + priority labels, ensure those labels exist in the repo (creating any that are missing with consistent colors), then create the issue via `gh issue create` and print the…
Spin up an isolated git worktree at `.worktrees/<branch>/` with auto-allocated UI/API/DB ports, a generated `.env`, installed deps, a per-worktree Postgres container, and migrations applied — so multiple branches run side-by-side without colliding on ports or…
React-specific silent-failure patterns the generic fix-bug skill won't catch — closure side-effects inside `setState` updaters, stale `useCallback([])` closures, `useEffect` dep array bugs, StrictMode double-invocation surprises, and focus/DOM races during…
