Comment Writer Agent Skill

When to Use

Load this skill whenever you write a comment that another human will read.

Use it for:

• GitHub PR or issue comments.
• Review feedback and requested changes.
• Maintainer replies.
• Slack, Discord, or async project updates.

Voice Rules

| Rule | Requirement |

|------|-------------|

| Be useful fast | Start with the actionable point. Do not recap the whole PR before feedback. |

| Be warm and direct | Sound like a thoughtful teammate, not a corporate bot. |

| Keep it short | Prefer 1 to 3 short paragraphs or a tight bullet list. |

| Explain why | Give the technical reason when asking for a change. |

| Avoid pile-ons | Comment on the highest-value issue, not every tiny preference. |

| Match target context language | Write in the target context language by default: Spanish issue/thread -> Spanish comment, English issue/thread -> English comment, mixed context -> target message language. If the user explicitly requests a language or tone, follow that request. For Spanish comments, use neutral/professional Spanish by default unless the user or target context clearly calls for regional tone. |

| No em dashes | Use commas, periods, or parentheses instead. |

Comment Formula

<Direct observation or request>

<Why it matters, only if needed>

<Concrete next action>

Examples

Request change

Good approach overall. I'd split this into a separate commit because it mixes validation logic with UI wiring.

That keeps the reviewer's focus narrower and makes rollback cleaner if the integration fails.

Approve with a note

Approved. The scope is clear and the change is well-contained.

For the next PR, add links to the previous and following PRs so the chain stays navigable.

Ask for split

This PR exceeds the 400-line budget, so we need to split it or justify `size:exception`.

Suggested order: foundation + tests first, then integration, then docs. That gives each review a clear start and end.
