Problem

CONTRIBUTING.md was 195 lines, and about half of it described how triage automation works. It did not say the main thing clearly: we take bug fixes from outside the team, and not features.

Change

CONTRIBUTING.md is now 130 lines and opens with a plain statement of who should contribute and what we close.

New in the guide:

  • A list of the PR types we close: features, UI overhauls, new providers, architecture overhauls, new source control methods, new auth methods, and new platforms.
  • The best way to help is to find things we can close: duplicates, fixed bugs, and dead PRs.
  • A +1 on an existing PR is always better than another PR.
  • Bans for automation spam and for making review harder.

Two policy changes come with it:

  • A feature PR is closed, even with a linked discussion. The one exception is a PR that a maintainer asked for.
  • The "focused configuration option" route is gone. A setting that adds a workflow or changes a default is a feature.

Kept, in shorter form: one problem per PR, evidence, banned models, the 3 open PR limit, the 7 day conflict window, and the 72 hour closure notice. All anchors that the triage skill and pr-limits.cjs link to still exist.

The triage internals were already in the contribution-triage skill, so they are deleted from the guide and not moved. The skill and the PR template are updated to match the new rules. The skill now names the model check itself, because the guide section that listed it is gone.

Verification

vp run check:changed passes. No code changed.

Approvability

Verdict: Approved at 99ba2d7

Macroscope's review found this PR approvable — This shortens contribution guidance and narrows outside PRs to bug fixes or maintainer-requested work. It affects contribution triage rather than product behavior, with reconsideration and maintainer protections retained.

Explain Change →

Walkthrough

The contribution guide, triage skill, and pull request template now state revised rules for outside-team contributions. The changes cover eligibility, issue links, verification evidence, model attribution, contributor limits, and closure guidance.

Changes: Contribution policy

Layer / File(s) Summary
Eligibility and scope
.agents/skills/contribution-triage/SKILL.md, CONTRIBUTING.md, .github/pull_request_template.md
The guidance defines bug-fix eligibility, treats workflow settings and default changes as features, and describes when feature PRs are closed. The template asks contributors to link a bug or maintainer request, or explain why an obvious small bug needs no issue.
Issue reporting and verification
CONTRIBUTING.md
The guide asks contributors to check for duplicate or superseded reports, report bugs in issues, and submit feature requests in Ideas discussions. It limits PRs to one problem and asks for verification details; UI changes require before-and-after screenshots, with a short video for motion or timing.
Review rules and contributor limits
.agents/skills/contribution-triage/SKILL.md, CONTRIBUTING.md
The guidance updates model attribution and spam reporting rules, sets a three-open-PR limit, and describes closure after seven inactive days in conflict or 72 hours after notice of a rule violation. The setup section links to the development runbook.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: Low · up to 99ba2

This documentation-only change has two wording inconsistencies that can confuse contributors about what counts as a feature and how long they have to respond before closure. There is no runtime or production risk, and the fixes are small wording edits.

Full details: Title check

Explanation

The title names the main change: CONTRIBUTING.md is shortened and states that only bug fixes are accepted. It uses the conventional "docs:" prefix and matches the changeset, which shortens CONTRIBUTING.md and limits outside contributions to bug fixes. The title omits the related template and skill updates, which is acceptable.

Full details: Description check

Explanation

The description follows the template's main sections (Problem, Change, Scope and approval, Verification) and explains the motivation, the policy changes, and the verification run. The Scope and approval section does not give the template's required linked bug issue or maintainer approval. It also does not explain how the verification covers the changed guidance, since the author reports only that check:changed passes and no code changed. The description also omits the template's model and harness attribution line. The template's 'Change' section asks for a description of how the change fixes a problem; this PR is a documentation change, so that is partly applicable. Overall the description is mostly complete, but the missing attribution and the unclear verification are gaps.

Resolution

Consider adding the model and harness attribution line that the template requests at the end of the Verification section. Also state the focused checks that show the changed guidance is consistent, and link the triaged issue or note why this docs-only change needs no prior issue.

A PR must fix a bug. A crash, a regression, and a real performance problem are bugs. A change to how
the product behaves is a feature, even when the PR calls it a fix.

Define features by intended behavior, not by any behavior change.

Line 62 defines a feature as "a change to how the product behaves." A crash fix also changes observable behavior. Read literally, the sentence contradicts the bug definition on line 61. The triage skill uses intended behavior as the test, so the guide should state the same test.

Qualify the 72-hour closure promise.

The guide promises a 72-hour window for every rule violation. Two paths close a PR without that window:

  • The three-open-PR limit closes a fourth PR when it is opened (CONTRIBUTING.md line 99).
  • When PR_LIMITS_ENFORCE is not true, the triage skill closes the PR right after it posts the explanation (the "Closure warranted" bullet in .agents/skills/contribution-triage/SKILL.md).

The conflict rule uses a seven-day inactivity window, which also differs from 72 hours. A contributor on these paths has no time to reply or push before closure.

The guide text needs to state these timings. The enforcement-off path in the skill is a policy choice: either it honors the 72-hour window, or the guide documents the immediate close. The diff below fixes the guide sentence only.
