vscode: Skill for Claude Code

.github/skills/sweeper-implement/SKILL.md

sweeper-implement is a skill for Claude Code, Codex from microsoft/vscode. It costs 187 tokens per session (3,398 once invoked), scanned A, original, MIT.

A procedure for implementing a VS Code issue that a review has already judged ready to build, then checking the change and preparing a draft pull request.

In plain words
What is it for?
Use it to implement a reviewed bug fix or feature, add the required test, validate the result, and leave a draft pull request for a maintainer.
Why use it?
It turns an agreed issue description or plan into a focused code change without making the agent redo the earlier investigation.

This is microsoft/vscode's own configuration. It tells Claude Code and Codex how to work on vscode itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything vscode configures →

About the project

Visual Studio Code is a code editor that supports editing, navigating, understanding, debugging, and extending software projects. Developers use it for the edit-build-debug cycle, and the catalogue add-ons provide skills, instructions, and agents for working within the editor.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sweeper-implement scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

sweeper-implement — implement a sweeper-reviewed issue

You are working on a single microsoft/vscode issue on behalf of the maintainer who invoked you. The VS Code Sweeper reviewed it, judged it agent-ready, and wrote a brief while tracing it in the source. You implement the issue and end in a draft PR the maintainer owns. What you implement from depends on the record's tier:

  • implement record → the brief. The review did the diagnosis (confirmed defect, bounded change, a named validation); you turn the brief into the smallest correct change plus a test. There is no plan file (Sweeper mode: implement).
  • plan record → the approved plan file, .sweeper/plans/issue-<issue-number>.md, written with the maintainer by the sweeper-plan skill; the maintainer asking you to implement it IS the approval (Sweeper mode: plan-first).

Below, the spec means whichever of the two you are working from. You never plan a plan record yourself — that is the sweeper-plan skill's job.

Keep the chat short: the maintainer reads the spec and the diff in their editor, not pasted into the conversation. Inside a question or choice prompt, write file paths as plain text — those prompts don't render markdown links.

0 · Preconditions (refuse if unmet)

  • The working directory must be a microsoft/vscode checkout — git remote -v must list microsoft/vscode. If not, stop: "run this from your vscode checkout".
  • The checkout must have no tracked modifications and no staged changes (git status --porcelain, ignoring untracked files). Dirty → stop and say so; do NOT stash, discard, or commit the maintainer's work-in-progress. Untracked files may stay — the ship step commits only files this skill created or edited.
  • gh auth status must succeed (the gates and the PR need it).

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
