Comment Hygiene

Comment Hygiene

Response Contract

• Deliverable: apply the requested changes to the target artifact.
• Chat output: no additional output beyond the deliverable.

Skill Model

This model classifies what can be commented. It does not imply quality.

Comment Attachment Sites

• Surface Public entry points and externally visible surfaces.

• Data Data shapes and schemas.

• Rule Rule-bearing logic and decision points.

• External External coupling and external constraints.

Standards

Each standard is defined once here and referenced elsewhere by its ID.

• site.assign — Assign a site Every comment must be assignable to exactly one attachment site: Surface, Data, Rule, or External.

• site.focus.surface — Surface focus Surface comments cover externally visible meaning and caller-facing constraints.

• site.focus.data — Data focus Data comments cover representation meaning and structural constraints.

• site.focus.rule — Rule focus Rule comments cover rule intent and rule boundaries.

• site.focus.external — External focus External comments cover external assumptions and external constraints.

• site.closest — Place at the closest site Place the comment at the closest location where a reader needs it for the assigned site and focus.

• comment.no_narration — No narration Remove comments that restate adjacent code or narrate straightforward steps.

• comment.nonoverlap — No overlap Avoid multiple comments that cover the same point. If one note spans multiple sites, split it so each comment has one site and one focus.

• comment.precise — Precise and scoped Use specific terms and explicit conditions. Keep scope bounded to what the assigned site and focus need.

• comment.stable — Prefer stable content Prefer describing intent, constraints, and externally relevant meaning over volatile implementation detail.

Workflow

1. Enumerate existing comments and planned comments.
2. Assign each comment to exactly one attachment site and confirm it matches the site focus. Apply site.assign and site.focus.*.
3. Delete narration and restatement. Apply comment.no_narration.
4. De-duplicate overlapping points. Apply comment.nonoverlap.
5. Relocate comments to the closest location where readers need them. Apply site.closest.
6. Rewrite remaining comments to be specific and bounded. Apply comment.precise.
7. Prefer stable content over volatile detail. Apply comment.stable.
8. Run acceptance checks.

Acceptance Criteria

A revision is complete only if all checks pass.

• Response: Output satisfies the Response Contract.
• Standards satisfied: site.assign, site.focus.*, site.closest, comment.no_narration, comment.nonoverlap, comment.precise, comment.stable.
