Skill Codex
Shape a task before implementation, then pressure-test the proposed shape with a council made of a Codex subagent on gpt-5.6 with high reasoning and pi/fable via the pi CLI. Use when the user asks to shape, plan, design, scope, or pressure-test non-trivial work with council feedback before deciding what to implement.

Use when the user wants to continue in a fresh session, hand work to another agent, preserve current context near context limits, or create a compact continuation brief for later. Use when they say handoff, next session, fresh agent, continue tomorrow, context limit, or pass this to another agent.
Skill Claude CodeCodex
Use when deciding which layer a piece of code belongs in (domain, application, or infrastructure), when business rules are mixed with framework/UI/database/HTTP code, when an external SDK or API response shape is leaking into core logic, when a test forces you to mock your own classes or sibling collaborators, or when…
Skill Claude CodeCodex
Use when planning features, designing changes, stress-testing ideas, scoping work, or deciding how to approach non-trivial implementation. Use when the user says plan, design, shape, grill, think through, prototype the idea, or asks for an implementation plan.
Skill Claude CodeCodex
Use before any code, config, or documentation edit. Use when the request uses vague verbs like "refactor", "clean up", "improve", "modernize", or "make better". Use when adjacent issues (dead code, bad style, smells, TODOs) are visible during a focused task. Use when tempted to do "while I'm here" cleanup.
Skill Claude CodeCodex
Use when debugging any bug, failing test, flaky behavior, performance regression, unexpected runtime behavior, or reviewing an existing bug theory/postmortem. Use before reading source code to explain a symptom, before proposing a fix, or when tempted to patch from inspection.
Skill Claude CodeCodex
Use when implementing features, fixing bugs (including P0 hotfixes and production incidents), refactoring, removing dead code, or deleting legacy paths. Use when user mentions TDD, red-green-refactor, test-first, or when tempted to write code before tests. Use when fixing any bug — even trivial ones. Use when…
Skill Claude CodeCodex
Use when running an unusually strict code quality review focused on maintainability, structural simplification, abstraction quality, spaghetti growth, giant files, type boundaries, and whether a branch should be blocked despite passing tests. Use when the user says thermo-nuclear review, thermonuclear review, harsh…
Skill Claude CodeCodex
Use when creating, editing, pruning, splitting, merging, or testing agent skills. Use when deciding skill frontmatter, model-vs-user invocation, description triggers, supporting files, pressure scenarios, or whether a skill should exist.
Skill Claude CodeCodex
Run independent thermo-nuclear code-quality reviews with a three-member council, then verify and reconcile their findings. Use when the user asks for review with council, thermo-nuclear review with council, or a council re-review of a PR, branch, or working-tree change.
