delorenj Skill

Create and remove test records on Integrity Pest Management's LIVE GorillaDesk account so Workflow 1 can be exercised end to end without being able to touch a real customer. Covers the geographic write fence, the board format (a whole day of jobs as one committed JSON file), the scenarios, the approver credential, and the exact commands. Use when asked to make test users or test jobs, to stage an acceptance run, to build an edge case (twins, no house number, back-to-back), to clean the account up, or when a closeout has nothing to match against. Triggers - test users, Miami Beach, testbed, job set, board, relay-testbed, stage a call, create a test job, clean up test data, write scope, blast radius. Do NOT use to write CLOSEOUTS (that is the relay itself) or to change job status (that is gorilladesk-private-api).

jacob-balslev Skill

Use when deciding whether to route a task to the fast/cheap tier (Claude Haiku) — transcription, polling, format conversion, structured-output slot-filling, small-diff review, high-volume low-latency work — and where the boundary is that should escalate to Sonnet/Opus. Covers the cost/latency floor, the 200K context ceiling (vs the upper tiers' 1M), the absence of the effort knob, the separate rate-limit pool, and when to drop below Haiku to a script. Do NOT use for ordinary multi-step feature work (use claude-sonnet), the hardest reasoning (use claude-opus), loop design (use autonomous-loop-patterns), or Claude API request syntax (read the claude-api reference).

jacob-balslev Skill

Use when adding or enforcing lint rules as part of a test or verification plan. Extends testing-strategy with lint-specific guidance: rule selection, gate placement, failure triage, and migration planning when introducing rules to an existing codebase. Do NOT use standalone — load the base testing-strategy skill alongside it — and do NOT use for chasing a specific lint failure in one file (that is debugging). Do NOT use for decide whether to unit-test or integration-test this handler. Do NOT use for extract this repeated code pattern into a shared util.

jacob-balslev Skill

Use when discovering a domain through events, commands, actors, policies, aggregates, read models, external systems, and temporal workflows before implementation. Do NOT use for event schema/topic contracts (use `event-contract-design`), webhook handler implementation (use `webhook-integration`), generic state transition modeling (use `state-machine-modeling`), or persistence schema design (use `entity-relationship-modeling`).

jacob-balslev Skill

Use when designing time-based scheduled work in web applications: Vercel Cron routes, Inngest cron-triggered functions, recurring-job idempotency, overlap prevention, retry/failure handling, UTC/timezone decisions, and monitoring for missed or failed schedules. Covers cron expressions, scheduler selection, authorization of cron endpoints, dispatch-to-worker patterns, execution-window idempotency, concurrency locks, and heartbeat/alert design. Do NOT use for general background job queue architecture (use background-jobs), event-driven orchestration without a time trigger, browser freshness transports, or one-off task debugging unrelated to recurring schedules. Do NOT use for move a slow export out of an API handler but it is user-triggered, not scheduled. Do NOT use for design a generic queue contract with retries and progress. Do NOT use for choose Server-Sent Events versus WebSockets for live progress. Do NOT use for define an event payload schema for an async integration.

jacob-balslev Skill

Use when designing end-to-end tests that exercise a user-visible path through the whole system, including the UI layer: the user-journey unit-of-test that distinguishes e2e from integration testing, the five-primitive structure (user journey, environment, test data, observable assertion, recovery), why e2e tests are expensive and how to keep them few-and-load-bearing, the wait/synchronization discipline that makes them not-flaky, the page-object and trace-test patterns, the role of e2e tests in the test pyramid/trophy (the top tier — fewest in count but highest in coverage of user-observable behavior), and the modern e2e tool landscape (Playwright, Cypress, Selenium). Do NOT use for testing internal seams of the system (use integration-test-design), single-unit isolated tests (use testing-strategy + test-doubles-design), consumer-driven contract verification (use contract-testing), or visual regression of specific components (use snapshot-testing).

jacob-balslev Skill

Use when mapping a user's experience across multiple touchpoints and time, surfacing emotional peaks and troughs, identifying opportunity moments in a cross-channel flow, or aligning a team on the end-to-end experience including back-stage support processes. Do NOT use for decomposing a single screen into UI steps (use task-analysis) or for drawing back-end service architecture diagrams — journey maps describe human experience, not system topology. Do NOT use for Break down the steps a user takes inside the upload modal. Do NOT use for Draw the microservice call graph for the checkout API. Do NOT use for Diagram the database schema for the order entity.

jacob-balslev Skill

Contract testing: interface verification between consumers and providers via shared contract artifacts and independent two-phase verification. Do NOT use for Test internal seams of a system (use integration-test-design). Do NOT use for Validate an HTTP response against an OpenAPI schema (use API-spec tooling). Do NOT use for Test a complete user journey through the UI (use e2e-test-design).

jacob-balslev Skill

Use when reasoning about snapshot testing as a tactical technique: capture-and-compare against a reviewed baseline, data snapshots, DOM snapshots, text/file snapshots, visual snapshots, approval-cycle discipline, snapshot churn, unstable inputs, large unreadable diffs, golden files, characterization tests, and visual regression review with tools such as Jest, Vitest, Playwright screenshots, Storybook/Chromatic, and Percy. Do NOT use for the overall test-level mix (use `testing-strategy`), universal property claims (use `property-based-testing`), test double construction (use `test-doubles-design`), strict test-first workflow design (use `test-driven-development`), or end-to-end user journey design (use `e2e-test-design`). Do NOT use for choose the overall unit integration e2e and performance test mix for this feature. Do NOT use for use property-based testing with fast-check generated arrays to assert sort output is ordered and preserves items.

jacob-balslev Skill

Use when designing browser-facing freshness for live dashboards, notifications, progress views, feeds, and data that can change after initial render. Covers freshness contracts, transport choice among adaptive polling, Server-Sent Events, and bidirectional sockets, webhook-to-UI propagation, client cache invalidation, stale-data indicators, reconnect and catch-up behavior, centralized subscription ownership, and non-disruptive update UX. Do NOT use for low-level stream/backpressure protocol design (use `streaming-architecture`), async event envelope/topic contracts (use `event-contract-design`), recurring schedule design (use `cron-scheduling`), durable worker execution semantics (use `background-jobs`), generic UI action feedback (use `interaction-feedback`), or serialization/trust boundaries (use `client-server-boundary`). Do NOT use for design the backpressure protocol for an HTTP stream. Do NOT use for choose the cron expression for a daily refresh.

jacob-balslev Skill

Use when observing representative real users attempting realistic tasks on a prototype or live product to surface usability issues: moderated or unmoderated, remote or in-person, concurrent or retrospective think-aloud, task scenarios, participant screening, tree/first-click testing for IA findability questions, pilot runs, severity rating, sample sizing by claim type, and ethical recording/consent. Do NOT use for automated test suites, code coverage, CI pipelines, unit/integration testing, load testing, or replacing participants with AI/synthetic users; those are engineering verification or synthetic-analysis concerns, not human-behavior observation. Do NOT use for Add unit tests for the order-total calculation function. Do NOT use for Set up the CI pipeline for the new repo. Do NOT use for Run a load test against the checkout API. Do NOT use for Run a card sort to design the navigation hierarchy and labels for this site. Do NOT use for Cluster the findings from ten completed user sessions into themes.
