SKILLEX

Use this skill when the user wants a repeatable, auditable implementation workflow for a non-trivial coding task, especially a feature, refactor, migration, or bug fix that should leave repo-local proof in .agent/tasks/<TASK_ID>/.

All task artifacts created by this workflow must stay inside the repository.

When the examples below mention scripts/task_loop.py, that path is relative to this skill root. Run it while your shell working directory is inside the target repository.

What this skill does

1. Initializes a strict repo-local task folder under .agent/tasks/<TASK_ID>/
2. Seeds or updates the required artifact files
3. Installs project-scoped Codex and Claude subagent templates into .codex/agents/ and .claude/agents/
4. Updates the repo-root AGENTS.md Codex baseline plus the repo's Claude guide file (CLAUDE.md or .claude/CLAUDE.md) with a managed block that explains the workflow
5. Guides the agent through a strict loop:

- spec freeze - builder implementation - evidence packing - fresh verification - minimal fix - fresh verification again until PASS
