## Description

V2-native deterministic contract for the owning CocoPlus feature. Executes the behavior formerly delegated to behavior-maturity skill without registered runtime scripts.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

Your objective is to perform this V2-native feature behavior using Coco-native capabilities: Read, Write, Edit, Bash when explicitly needed by the host, Snowflake tools when the feature requires data access, and subagents when the feature requires independent review.

## Required Contract

- Preserve the artifact paths, schemas, and user-visible outputs documented by the owning feature skill.
- Do not call legacy scripts as the implementation path.
- Prefer deterministic file parsing and structured artifacts over free-form prose when producing machine-readable state.
- If an external side effect would occur, apply the same gate and confirmation semantics as the owning feature.

## Exit Criteria

- [ ] The owning feature's documented artifact is produced or updated.
- [ ] The output schema remains compatible with existing readers.
- [ ] No registered runtime script invocation is required.

## Anti-Rationalization

| Shortcut / Temptation | Why It Fails |
|-----------------------|--------------|
| Treat the skill as complete because the file exists | Skill contracts must describe observable behavior and verification, not just command names. |
| Skip artifact and safety checks for a small command | Small commands still mutate state or guide execution; preserve the same gates. |
