| description | How to open and shepherd a pull request at ChainSafe — language-agnostic PR authoring guidance. Use this skill whenever the user is opening a PR, drafting a PR description, deciding how to scope a PR, handling reviewer comments, structuring commits within a PR, declaring AI-generated content, or shepherding a PR through review. EVEN IF the user does not explicitly say "PR" — triggers on "open a pull request", "draft a PR description", "what should I put in the PR", "PR is too big", "split this PR", "how do I respond to this reviewer comment", "self-resolve threads", "AI declaration in PR", "scope drift", "commit message", "stack of PRs". For the actual code-change workflow that produces the PR, use chainsafe-research-plan-implement. For PR review (incoming), use chainsafe-code-review. |

PR Authoring
How to open and shepherd a PR at ChainSafe. Language-agnostic; language-specific reviewer surface is in the language skills. Full reference: workflows/pr-authoring.md.
Branching
Branch naming follows OneFlow: personal feature branches are <name>/<feature>. PRs target main unless your CODEOWNERS designate otherwise.
Default workflow for non-trivial PRs
For any substantive code change, the canonical workflow is the chainsafe-research-plan-implement skill: research → plan → annotate (1–6 rounds) → implement. This skill enforces a human-approved plan before any code change.
When the PR author is an agent, the skill is loaded and followed. When human, the same shape applies — research artifact when context is non-obvious, plan when work touches more than one file, accept annotation, then commit code.
Small, focused, self-contained
- One PR, one self-contained change. Reviewable in ~10 minutes.
- Separate refactors from features/fixes. A refactor is its own PR (exception: tiny refactor genuinely entangled with the feature, <~50 lines).
- Renames, deletions, generated-code PRs can be large — they trade scope-width for shallow review depth.
- Stack PRs for sequential work rather than one big PR.
The right question: is this change related to the PR's stated goal, or can it live on its own?
PR description required fields
- What changed — 2-3 sentences, plain language.
- Why it changed — link to issue/ADR/spec or write inline.
- Acceptance criteria or test plan — what "done" looks like; how to verify.
- Out-of-scope notes — anything the reader expects to see in the diff but doesn't.
- Operational impact — env vars, secrets, config, schema/migrations, or ports added or changed; backwards-compat impact; what Infra or the owning team must do. "None" is valid but must be answered (Engineering Invariant 8; contract-altering changes trip the operational-contract gate).
Agent-era additions
- AI-generated declaration. If an agent drafted substantive portion, say so. "Drafted by Claude Code following
chainsafe-research-plan-implement; reviewed by @author" works.
- Link to the plan artifact (research.md, plan.md) so reviewers see what the operator approved.
- Assumption surfacing — non-obvious assumptions the agent made without explicit operator confirmation, called out for review.
- Scope drift flags — any file touched that wasn't in the original ticket scope, named with a one-line reason. This is the scope-discipline invariant made visible.
Commits
- Commit messages describe intent, not just diff.
- Responses to reviewer comments land as new commits, not as edits to existing ones.
- Squash on merge if the repo's convention is squash; otherwise let the commit train through. Defer to CODEOWNERS.
Reviewer requests
- CODEOWNERS auto-routes; don't override unless adding to that list.
- No CODEOWNERS? Use the two-team pattern:
<project>-admins for senior, <project> for peer.
- Blocked on review >1 business day → ping reviewer in team channel.
Handling reviewer comments
- Address every comment. Either change the code or reply explaining the choice.
- Don't self-resolve threads unless the change is trivial (typo, lint). Reviewer resolves their own comments.
- Disagreements escalate. Get a third opinion from CODEOWNER or curator. Don't merge through a disagreement.
- For agents: when an operator review surfaces a misunderstanding of the original plan, update the
plan.md first, then re-implement the affected slice. Keep the plan as source of truth.
Anti-patterns
- The mega-PR. "It's all related" — usually it isn't.
- The drive-by refactor.
- The silent re-scope.
- The agent ghost-author (no AI declaration).
- The "fixed it" reply (no detail).
