The sweeper-fix skill

Let an agent implement a sweeper-reviewed fix for one of your microsoft/vscode issues — from your own checkout, under your own identity, as a draft PR you own.

What the sweeper did for you

The sweeper reviewed the open microsoft/vscode backlog with a source checkout and marked the issues an agent can fix — each with a fix spec written while tracing the defect: the observable problem, the fix boundary (what must not change), the likely files, and a validation that becomes the regression test. Your ranked list is on your top-issues page (filter: agent-fixable), and every spec is inspectable there before you run anything.

Using it

No setup. The skill ships in the vscode repo itself (.github/skills/sweeper-fix/), so an up-to-date checkout already has it — just pull a recent main.

Then paste the prompt the Copy prompt button put on your clipboard — the skill invocation plus the reviewed spec, so you can read (and edit) what the agent is asked to implement before sending:

Fix microsoft/vscode issue #262104 using the sweeper-fix skill.

Reviewed fix spec (edit freely — the skill re-checks the live gates and treats this as your intent):
<the record's fix brief — pasted for you to read and adjust>
Likely files: …
Validation: …

Editing the spec is fine — the skill implements your version and still runs every gate. A bare first line alone works too (the skill then reads the record's spec itself).

What to expect

• Live gates first. The skill refuses if the issue is closed, security-labeled, not reviewed as agent-fixable, or already has an open PR — and warns if the issue changed since its review.
• The fix + a test. It implements the review's fix spec narrowly and adds the validation as a test that fails before the change and passes after.
• You approve the diff. Nothing is pushed until you've seen the full diff and said go.
• A draft PR you own. Branch <you>/fix-<n>, base main, body carries Fixes #n and a "seeded by" link to the review record. You review, flip to ready, and merge — or close it. The sweeper never touches the PR again.

Troubleshooting

• Skill doesn't trigger? Say "sweeper-fix skill" explicitly (agents match on the skill description). Copilot CLI loads skills at session start — restart it after pulling a checkout that just gained the skill.
• "Not agent-fixable" refusal? The review found no safe fix spec for that issue — the skill only implements reviewed specs. Check the record linked from the dashboard for what the review concluded instead.
• Skill still not found? Check your checkout has .github/skills/sweeper-fix/SKILL.md — pull a recent main if not. On an older checkout you can't update, copy the generated SKILL.md into ~/.copilot/skills/sweeper-fix/SKILL.md (Copilot CLI) or ~/.claude/skills/sweeper-fix/SKILL.md (Claude Code).
