accelint-archive-synthesis
Periodically lint the full OpenSpec archive for cross-change decision drift, index/spec reconciliation, and structural over-coupling, the gap nothing else in the QRSPI/OpenSpec stack covers, since every other drift check (accelint-onboard-openspec, accelint-architecture-doc, accelint-qrspi-apply Phase 4) only looks forward from a single change's own artifacts. Use this skill when the user wants to "run archive synthesis," "lint the openspec archive," "check for decision drift," "audit the spec archive for contradictions," "find stale specs," "reconcile the specs index," "check capability coupling," or when accelint-qrspi-archive has surfaced its own suggestion that 15+ changes have archived since the last synthesis run. Also use when the user asks whether an old design decision still holds given everything decided since, whether specs/INDEX.md still matches the actual spec.md files on disk, or whether some capability has become an over-coupled refactor candidate. This skill never runs automatically and never blocks another skill — it is always either a human-invoked audit or an offered suggestion the human accepts explicitly.
accelint-ac-to-playwright
Convert and validate acceptance criteria for Playwright test automation. Use when user asks to (1) review/evaluate/check if AC are ready for automation, (2) assess if AC can be converted as-is, (3) validate AC quality for Playwright, (4) turn AC into tests, (5) generate tests from acceptance criteria, (6) convert .md bullets or .feature Gherkin files to Playwright specs, (7) create test automation from requirements. Handles both bullet-style markdown and Gherkin syntax with JSON test plan generation and validation.
accelint-eval-architect
Use when users say "add an eval to this skill", "evaluate this skill/agent", "evaluate this tool/repo/pipeline", "how should I test this RAG bot / retrieval / parser", "set up DeepEval/Ragas", "should I use Promptfoo/Inspect", "is my eval any good", "audit my eval harness" — or when they describe symptoms like "my bot is hallucinating", "answers got worse after a prompt/model change", "this regressed and nothing caught it", or want CI/regression checks for prompts or LLM output. Assesses the target (an LLM skill OR a standalone tool repo, e.g. a RAG/retrieval pipeline), recommends DeepEval, Ragas, a deterministic harness, or human-review-only and scaffolds it; Promptfoo and Inspect AI are recommended with hand-off guidance when they fit (not scaffolded). Also audits existing eval harnesses for stale fixtures, toothless metrics, and uncalibrated thresholds. Make sure to use this whenever someone wants to measure, test, regression-check, or benchmark what a skill, agent, tool, or RAG pipeline produces.
accelint-nextjs-best-practices
Next.js performance optimization and best practices. Use when writing Next.js code (App Router or Pages Router); implementing Server Components, Server Actions, or API routes; optimizing RSC serialization, data fetching, or server-side rendering; reviewing Next.js code for performance issues; fixing authentication in Server Actions; or implementing Suspense boundaries, parallel data fetching, or request deduplication.
accelint-architecture-doc
Create or update a living ARCHITECTURE.md for a codebase. Use when the user wants to write, refresh, restructure, or maintain an architecture document; document how the system is organized across tech stack, deployment model, services, components, and data stores; or turn codebase findings into durable architecture docs for engineers or agents. Trigger on requests such as write an architecture doc, document this system, create or update ARCHITECTURE.md, give me a technical overview of this repo, or map out how this app is put together, even when the file is not named. Prefer this skill for file-producing architecture documentation, not for generic architecture advice, implementation planning, or diagram-only brainstorming unless that work is clearly part of updating the document.
accelint-design-foundation
Use when styling components or elements with @accelint/design-foundation or @accelint/design-toolkit packages, or when users say "style this", "add styling", "theme this component", "add colors", "add spacing", "CSS modules", "setup design foundation", "@variant", or when working with .module.css files. Provides opinionated Tailwind conventions including semantic tokens, custom spacing scale, outline-based borders, variant system, and CSS module setup guidance.
accelint-english-manager
Use when the user wants prose rewritten, tightened, audited, simplified, polished, humanized, grammar-checked, or made plainer, clearer, shorter, easier to scan, or easier to act on without changing the intended meaning, audience, tone, or explicit constraints. Trigger on requests such as plain English, simple English, make this clearer, make this more direct, clean this up, edit this, review this writing, grammar check, too wordy, too formal, less fluffy, friendlier, shorter, audit then rewrite, keep the tone, mode=strict, STE, ASD-STE100, or ADHD-friendly. Also trigger for docs, prompts, emails, UI copy, support replies, release notes, status updates, incident notes, procedural text, and other LLM-written prose. Prefer this skill when the main job is improving English prose or preserving tone while increasing clarity, including audit-only requests and exact-text-preservation constraints, but not when the real task is fact-checking, policy setting, or substantive content design.
accelint-onboard-agents
Onboard a repository to agent-driven development by creating or refreshing a complete AGENTS.md or CLAUDE.md through behavior-focused discovery, structured interviewing, drift-aware updates, conflict-aware synthesis, proportional updates, and preview-before-write review. Use when the user wants to create, replace, refresh, import, restructure, append to, dry-run, or review AGENTS.md or CLAUDE.md guidance, mentions agent behavior, instructions, guardrails, workflow, Claude Code conventions, package-level agent files, or monorepo inheritance, or asks how to tell an AI coding agent how to behave in a project. Also use it when the user wants behavior rules kept separate from `openspec/config.yml` or `openspec/config.yaml` project DNA. Do not use it for OpenSpec config onboarding, architecture docs, or one-line AGENTS.md or CLAUDE.md edits that do not require discovery, synthesis, or section-level review.
accelint-onboard-openspec
Interactively onboard a project to OpenSpec by running a structured interview and generating a complete QRSPI-configured openspec/config.yaml. Use this skill whenever a user mentions "openspec config", "config.yaml for openspec", "set up openspec", "onboard to openspec", "generate openspec config", "QRSPI config", or asks how to configure OpenSpec for their project — even if they just say "help me set up openspec" or "I want to use openspec". Always prefer this skill over ad-hoc config generation.
accelint-persona-review
Evaluate Figma designs from operator persona perspectives through design critique and user experience evaluation. Use when reviewing UX for specific user roles (e.g., air-surveillance-tech, weapons-director), conducting design reviews, or evaluating operator interfaces. Analyzes cognitive load, communication patterns, pain points, and system visibility. Works with Figma MCP (desktop/URL) and Outline docs.
accelint-ts-documentation
Audit and improve JavaScript/TypeScript documentation including JSDoc comments (@param, @returns, @template, @example), comment markers (TODO, FIXME, HACK), and code comment quality. Use when asked to 'add JSDoc', 'document this function', 'audit documentation', 'fix comments', 'add TODO/FIXME markers', or 'improve code documentation'.
accelint-prompt-manager
Turn user-provided requests, drafts, or prompt text into clearer, more executable prompts without performing the underlying task. Use when the user explicitly wants to improve, rewrite, optimize, tighten, clarify, structure, or adapt a prompt, when they have an idea but do not know how to phrase it, or when the prompt is missing audience, constraints, format, execution context, or success criteria. Also use for system prompts, meta-prompting, prompt frameworks, Claude Code prompts, and batch or API prompt design. Do not use when the user mainly wants the task executed, researched, or implemented rather than the prompt improved.
accelint-qrspi-apply
Implement QRSPI-planned OpenSpec changes with intelligent parallelization. Use when the user wants to apply a QRSPI change, implement tasks with parallelization, or says "apply this QRSPI change", "implement with parallelization", "run the parallel slices". This skill is specifically designed for changes created via accelint-qrspi that include "Parallelization Strategy" sections in tasks.md. It orchestrates parallel sub-agent execution for independent task slices using OpenSpec CLI workflows. Make sure to use this skill when the user mentions applying QRSPI changes, running parallel implementation, or working on changes with vertical slices.
accelint-qrspi-archive
Archive an OpenSpec change end-to-end. This skill invokes openspec-archive-change or openspec-bulk-archive-change itself to perform the native merge, then immediately follows up with the cross-capability linking and running indices OpenSpec doesn't build on its own — linking every capability a change touched via a shared `related:` frontmatter list, keeping `openspec/specs/INDEX.md` current, and appending a row to `openspec/changes/archive/INDEX.md`. Use this skill whenever the user wants to archive a change, says "archive this change", "bulk archive these changes", "run openspec-archive-change", "run openspec-bulk-archive-change", "update the specs index", "cross-link the specs", or wants the archived-change changelog kept current. This skill is purely additive on the linking side — it never prunes a `related:` entry and never changes a change's `Status` column after the initial write; that pruning/synthesis work belongs to `accelint-archive-synthesis`.
accelint-qrspi-propose
Use this skill when the user wants to start the formal QRSPI/OpenSpec planning workflow for a ticket, bug, feature request, or proposed product/CLI/app change before implementation. Invoke it when the user wants a spec-driven change package with questions first, factual research, proposal/design artifacts, affected specs, and a vertically sliced task plan, with explicit review/approval stops before any coding begins. This is the right skill when the user wants to plan, scope, or break down the change itself, especially if they ask to use QRSPI, create an OpenSpec change, run a planning workflow, or stop before writing code. Do not use it to implement an existing spec, review or polish artifacts that already exist, generate generic architecture docs, archive completed changes, or support loose brainstorming without a request for formal QRSPI/OpenSpec outputs.
accelint-react-best-practices
React performance optimization and best practices. ALWAYS use this skill when working with any React code - writing components, hooks, JSX; refactoring; optimizing re-renders, memoization, state management; reviewing for performance; fixing hydration mismatches; debugging infinite re-renders, stale closures, input focus loss, animations restarting; preventing remounting; implementing transitions, lazy initialization, effect dependencies.

Trigger keywords on vitest, *.test.ts, describe, it, expect, vi.mock, fast-check, fc.property, roundtrip, idempotence.
constraints-extractor
Extract explicit and implicit constraints (compliance, security, hosting, tooling, stakeholder, scope, and external-dependency boundaries) from a project's documentation, then build or update a canonical CONSTRAINTS.md. Spawns one subagent per source document to flag externally-imposed boundaries with evidence citations and confidence ratings, then correlates, deduplicates, and organizes the results by category before writing them into CONSTRAINTS.md. Use this skill whenever a user mentions \"CONSTRAINTS.md\", \"extract constraints\", \"find our constraints\", \"document constraints\", \"compliance constraints\", \"what limits this project\", \"synthesize constraints\", or wants to capture externally-imposed boundaries (legal, security, compliance, stakeholder, vendor) that shape what a project can build and how. Always prefer this skill over ad-hoc constraint documentation.
epistemic-mapper
Build or update a canonical EPISTEMIC-MAP.md sorting a project's knowledge into four states: validated Facts, open Questions, undocumented Assumptions, and inferred Risks. Purpose-built for prototype-to-production handoff, where a signed contract means a new engineering team must take over before the original builder's tacit knowledge walks out the door. Spawns subagents across docs and the codebase to find what's proven, what's asked, what's silently assumed, and what nobody has noticed, then runs a dedicated synthesis pass for systemic risks no single source states. Use whenever a user mentions \"epistemic map\", \"knowledge map\", \"EPISTEMIC-MAP.md\", \"known unknowns\", \"unknown unknowns\", \"what do we actually know vs assume\", \"map our assumptions\", \"handoff risk map\", \"prototype handoff\", or \"onboarding a team onto a prototype\". Always prefer this skill over ad-hoc knowledge-gap documentation.
jargon-extractor
Extract internal terminology, acronyms, shorthand, and jargon from a set of documents, then build or update a project glossary in JARGON.md. Reuse an existing JARGON.md anywhere in the repo if one already exists; otherwise default to the repo root. Spawns one subagent per input file to flag terms with plain English definitions, then a single reduce subagent correlates, deduplicates, and alphabetizes the combined results, intelligently merging any overlapping definitions before writing them into the glossary. Use this skill whenever the user asks to extract jargon, build or update a glossary, catalog acronyms, document internal terminology, flag undefined terms, or mentions a JARGON.md file by name, even if phrased casually, for example 'go through these design docs and pull out anything a new hire wouldn't know' or 'scan this repo's markdown files and build a term list.' Also trigger when the user hands over several documents and asks what specialized vocabulary or shorthand appears across them.
