Skill Claude CodeCodex
Creates specs before coding. Use when starting a new project, feature, or significant change and no specification exists yet. Use when requirements are unclear, ambiguous, or only exist as a vague idea. Use when a single requirement spans several independently testable capabilities.

Always-on. The main development method: Plan → TDD → Implement → Verify → Report. Use for ANY non-trivial task. Do not write code without a plan and a test. Complex tasks (>3 files) → split into atomic tasks. Bug fix → Prove-It Pattern (reproduce with a test before the fix).

Skill Claude CodeCodex
Drives development with tests. Use when implementing any logic, fixing any bug, or changing any behavior. Use when you need to prove that code works, when a bug report arrives, or when you're about to modify existing functionality.

Skill Claude CodeCodex
Use when the user wants to: add/fix tests, understand what is covered, determine whether something is "done", reproduce a bug with a test, check limits/rate-limit/failures, or when tests are written against a real DB/network. Covers: isolation from the prod store, domain-first tests, test names as a spec, boundary…

Skill Claude CodeCodex
Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback.

Skill Claude CodeCodex
Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always.

33Skill Claude CodeCodex
Use when you need a fact from the outside world: "find out", "look up", "what do they say about", "how it works", "compare", "find information". Protocol: web search → primary sources → cross-check → answer with sources. Do not use for searching the knowledge base (business-wiki) or for facts already in the Wiki.

Use when working with Windows (cmd/PowerShell console, MINGW64, script installation): stdout encoding (cp1251 vs UTF-8, UnicodeEncodeError on ✓/Cyrillic), CRLF/LF when writing files (md5 checks of mirrors), UTF-8 BOM for PowerShell 5.1, npm.cmd instead of npm, venv Scripts vs bin, PYTHONIOENCODING/PYTHONUTF8.

36Skill Claude CodeCodex
Always-on. Law of minimalism: don't build what wasn't asked for. Abstraction with one consumer → inline. New dependency → only if the pain is measurable. Dead code → delete. "For the future" → not a reason. Use for ANY code change.
