Delegate one agreed, bounded implementation block to MAINFRAME's project-scoped Pi engineer after the result, boundaries, acceptance criteria, and allowed checks are clear. Use new for a new block and resume for corrections to the active block. Do not use for requirements discovery, architecture decisions, open-ended…

Implement, debug, review, or plan server-side Python in FastAPI, Django, Flask, and established Python services. Use for HTTP APIs, business logic, authentication, PostgreSQL, SQLAlchemy, migrations, workers, realtime behavior, caching, object storage, external integrations, generated documents, observability, and…

Perform the final independent readiness check for a consequential task before a prepared decision is presented or an implemented result is accepted. Use only inside the owning advisor profile for preparation-readiness and final-state reviews; do not use for routine work, implementation, or adversarial decision review.

Apply the private evidence, source-selection, cross-checking, numeric-verification, and stopping method of mainframeresearcher. Use only when preloaded into that custom agent; do not expose this specialist method to primary skill discovery.

Safely discover and consume credentials already registered on this machine without reading, echoing, logging, copying, or persisting their values. Use when a command, remote service, HTTP request, SSH connection, deployment, or external CLI needs a credential or a registered service description.
Skill Claude CodeCodex
Design or audit a cross-cutting testing strategy when test levels, suite cost, infrastructure boundaries, reliability, or regression coverage need a deliberate decision. Use for test-suite audits, slow or misleading suites, coverage spanning several components, or deciding which guarantees belong in fast local tests…
Skill Claude CodeCodex
Record a concrete problem outside the active task's assigned result or agreed definition of done without expanding scope. Use when work reveals an incidental observation worth preserving or an explicitly assigned investigation confirms a problem with evidence. Do not use to replace unfinished in-scope work, scope…
Skill Claude CodeCodex
Search the current local repository or a named scope broadly for concrete plausible problems and record deduplicated ticket observations without fixing or fully confirming them. Use only when the user explicitly starts a ticket-discovery run in native Goal mode. Do not use for ordinary incidental findings, focused…
Skill Claude CodeCodex
Implement explicitly autonomous ready tickets one at a time, establish focused red evidence where useful, validate each complete fix, commit coherent recovery points, and queue results for independent verification. Use only when the user explicitly starts a ticket-implementation run in native Goal mode for the…
Skill Claude CodeCodex
Verify, scope, atomize, and consolidate open ticket observations, routing each result to ready technical work, a user decision, rejection, or an explicit evidence gap. Use only when the user explicitly starts a ticket-refinement run in native Goal mode for all eligible tickets or a named scope. Do not use for…
Skill Claude CodeCodex
Independently verify implemented tickets, archive proven fixes, and return failed work to the correct open queue without repairing it inline. Use only when the user explicitly starts a ticket-verification run in native Goal mode from a task that did not implement the queued work. Do not use for discovery, refinement…

Implement, debug, review, or plan server-side TypeScript in Node.js services, NestJS, Express, Fastify, and established Next.js server layers. Use for HTTP APIs, business logic, PostgreSQL, Prisma, TypeORM, Drizzle, auth, migrations, workers, queues, realtime communication, storage, resilience, observability, and…
