Playwright E2E testing patterns, cross-browser configuration, page objects, and CI setup. Use when creating E2E specs, visual regression suites, or configuring Playwright in CI. Trigger terms: playwright, e2e, trace, page object, cross-browser

Resend transactional email patterns, React Email templates, domain configuration, and webhook handling. Use when sending emails, building email templates, or configuring email delivery.

Prisma ORM schema design, migrations, client generation, and query patterns. Use when designing database schemas, writing migrations, querying data, or managing Prisma Client.

Generates test plans, writes unit/integration/E2E test files, identifies coverage gaps, flags common testing anti-patterns. Use when writing tests, creating test suites, planning test strategies, mocking dependencies, measuring code coverage, or test planning.

Saves, restores session state including task progress, file changes, delegation history. Use when saving progress, resuming interrupted work, picking up where you left off, or checkpointing current work.

Appends new entries to LESSONS-LEARNED.md via opencastle lesson CLI; searches past lessons for matching errors; proposes skill updates when retry patterns exceed thresholds. Use when consulting or updating LESSONS-LEARNED.md, after task failures, when capturing retrospective insights, or when a retry succeeds.

Four lifecycle hooks every agent runs: on-session-start scans LESSONS-LEARNED.md, resumes checkpoints; on-pre-delegate verifies tracker issues, file partitions; on-post-delegate runs fast-review, CI checks; on-session-end executes session guard, writes logs. Use when starting a new session, running pre-flight checks before delegation, coordinating between agents, reviewing a completed handoff, or wrapping up a session. Trigger terms: multi-agent setup, delegate tasks, agent coordination, session management, run pre-flight checks, start a new session, coordinate between agents, wrap up session

Mandatory post-delegation gate: checks output completeness, verifies acceptance criteria compliance, flags regressions, produces PASS/FAIL verdict. Use when checking delegated work against acceptance criteria, running post-delegation gate, validating agent output before acceptance, verifying sub-agent completed its assignment, or running post-delegation QA check.

Maps file dependencies, flags shared imports, groups files for safe parallel editing before code changes. Use when planning a refactoring, analyzing change impact, or understanding which files a modification will affect.

Deploy sites, configure serverless and edge functions, and verify builds on Netlify. Use when the user mentions: 'deploy preview', 'configure netlify.toml', or 'debug a failed deploy'. Trigger terms: build error, Netlify Functions, deploy logs, deploy preview

Figma design-to-code workflows, design token extraction, component inspection, and asset export. Use when translating Figma designs into code, extracting design tokens, or referencing component specs.

Provides model routing rules, validates delegation prerequisites, supplies cost tracking templates, defines dead-letter queue formats for Team Lead orchestration. Load when assigning tasks to agents, choosing model tiers, starting delegation session, running multi-agent workflow, delegating work, choosing which model to use, or assigning tasks.

Coordinate multiple agents: parallel spawning, health monitoring, circuit breakers, escalation. Use for parallel agents, agent timeouts, fan-out tasks, multi-agent delegation.

Defines named visual aesthetic, selects typography pairings, builds CSS token systems, adds entrance animations for high-design-quality pages. Use when user asks to design landing page, style marketing site, create distinctive UI theme, pick fonts, or add CSS animations — specifically when visual polish, brand identity matter rather than generic component scaffolding.

Vitest unit and integration testing patterns, commands, mocking (vi.mock), and coverage. Use when writing .test.ts files, configuring the test runner, or adding coverage thresholds.

Creates, queries agent expertise profiles in AGENT-EXPERTISE.md; increments file-familiarity counters after each task; ranks candidate agents by recency, task-area match. Use when deciding which agent should handle a file, checking who last worked on a module, recording task outcomes, or assigning work based on past performance.

Creates API route handlers, implements Server Actions with Zod schema validation, integrates external REST APIs with error handling. Use when adding endpoints, building request handlers, or wiring external services (endpoint, REST API, request handling, fetch, .ts route files).

Runs 3 isolated reviewer sub-agents; consolidates PASS/BLOCK verdict by majority. Use when user requests independent review of code changes, pull requests, design documents, or release notes.

Create and update Jira issues, epics, and sprints; manage backlog and sprint transitions. Use when you say: 'create a ticket', 'open a story', 'link an epic', 'start a sprint', or 'search the backlog'.

Manages Sanity CMS schemas, GROQ queries, dataset exports/imports, and Studio configuration. Use when updating Sanity schemas, running GROQ or Vision queries, exporting datasets, modifying content models, or configuring a headless CMS with Sanity.io.
