Do not use this skill for end-to-end customization generation; defer that to ub-customizations.
Do not use this skill for ordinary code implementation or framework work where no shared authoring contract is being changed.
Do not use this skill as a substitute for repo-local maintenance docs or packaging metadata that belong to a development repository rather than the distributable skill payload.

Embedded Contract

These rules are the base contract of this skill and must not depend on a secondary document to be applied correctly.

Treat descriptions as routing metadata, not marketing copy.
Add explicit non-use boundaries when wrong-skill activation is realistically costly or common.
Prefer concrete examples and acceptance boundaries over vague admonitions.
Keep the main skill surface lean and move deeper detail into targeted references.
Keep shared authoring guidance portable across installed skill payloads and avoid repo-local live truth in the reusable contract.
Keep reusable choice-question UX contracts in shared authoring guidance instead of re-encoding the same multiple-choice rules in each skill.

Load References On Demand

Read references/authoring-conventions.md when shaping shared skill structure, cross-skill wording, routing quality, reusable choice-question UX, or other reusable authoring patterns.

Decide whether the task is changing a reusable authoring convention or a single skill's local content.
Keep portable shared guidance in this skill and domain-specific guidance in the owning skill.
Normalize descriptions, examples, non-use boundaries, and shared choice-question behavior only where the changed surfaces actually benefit from them.
Keep reusable references installable and avoid dead links into repo-only docs.

When producing non-trivial authoring updates, include:
