PR Preflight

Interactive branch review before a PR is posted or updated. This is the orchestration layer: review policy lives in .github/instructions/review-analyzer.instructions.md, shared terminology in CONTEXT.md, and the write-up belongs to pr-pitch.

Tell the author what will happen before starting: setup, analysis, interview, then .review/summary.md and optionally the PR. During the interview they can explain, dismiss a finding with a reason, ask for a fix, or say they are unsure -- all of which get recorded.

Setup

Name the review model for the summary header -- GitHub Copilot when running in Copilot. Never invent an AI co-author trailer.

1. git branch --show-current. Stop if it is main.
2. git status --porcelain. If dirty, ask whether to commit first; in-review fixes will otherwise be committed alongside.
3. git fetch origin --quiet, then merge-base against origin/main. Record the file count and commit count.
4. If .review is not gitignored, ask to add it -- as its own question.
5. Ask the branch purpose in the author's own words, unless supplied.

Load CONTEXT.md and .github/context/codebase.context.md. If the purpose or title uses an overloaded FieldWorks term -- project, model, view, app, context, review, validation -- apply grill-with-docs before writing the summary, and carry the clarified term into the findings and PR copy.

Analysis

Run all four passes from review-analyzer.instructions.md:

1. Contracts, compatibility, correctness
2. Managed UI, C#, localization
3. Native, COM, boundary safety
4. Build, tests, CI, dependencies, installer

Use specialist read-only agents where the changed files justify one -- FieldWorks C# Expert, WinForms Expert, C++ Expert, Avalonia UI Expert (Avalonia work only), devils-advocate for large scope or risk arguments. Run the passes directly for a small diff. The synthesis is yours either way.

Per pass: compare against the merge base, verify each finding against the actual code before reporting it, and grade Critical / Important / Minor. Record positive observations and validation gaps too. Merge into one severity -ordered list; deduplicate only when two passes flagged the same file for the same concern.

Interview

5-15 questions. One Critical or Important finding at a time, unless several share a root cause.

Per finding: why is this safe or intentional, and what validation covers it? One follow-up if the answer is vague; if still unclear, record it unresolved.

For large, cross-boundary or non-obvious changes, ask separately:

"Can you walk me through the most complex or non-obvious part of these changes? I want to make sure I understand the reasoning."

Record lack of understanding literally. "The AI did it", "I'm not sure", or an explanation that never describes the mechanism becomes Author does not understand: <area>. Never soften it into acceptance.

Minor findings: print them all first. Three or fewer, ask whether to take them together; more than three, go one at a time.

Close with: "Anything else to flag -- trade-offs, uncertainties, context a reviewer should know?"

In-review fixes

Keep them minimal and scoped to the finding. git add, do not commit yet. Record each as INTERVIEW_CHANGES. Do not delete a fixed finding -- mark it [x] with a fixed-during-review note.

Then run the repo scripts, never ad-hoc msbuild / dotnet build / vstest.console / nmake:

Changed	Run
Anything build-affecting	./build.ps1 -CommentHygiene
Managed behaviour	./test.ps1 with the narrowest reliable -TestProject or -TestFilter
Native code or tests	./test.ps1 -Native -TestProject <p>
Installer, WiX, helper scripts	./Build/Agent/Setup-InstallerBuild.ps1 -ValidateOnly
Whitespace	VS Code task CI: Whitespace check

A -TestFilter that matches nothing still exits 0 and prints PASS -- check Total tests: N is above zero. Never mark manual validation complete unless you performed it or the author explicitly confirms it. Report skipped checks and why.

Summary and PR

Write .review/summary.md per references/summary-template.md.

Then offer -- and only act on confirmation:

"Summary written to .review/summary.md. Review it, make changes where appropriate, and re-run until you are ready. When you are, shall I commit, push and post the PR? I will update an existing one if there is one. The write-up runs through pr-pitch, which also triages the branch's research and working markdown into collapsed sections in the PR body and out of the tree -- you approve that triage before anything is deleted."

This skill never composes the description itself. Hand pr-pitch the branch purpose, the findings and the summary. For a branch named lt-1234-anything, prefix the PR title LT-1234: and write a sentence-case title from the actual change, not the branch slug.

After reviewers comment, use respond-to-review-comments.
