Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00094 | $0.01736 |
| Opus 5 | $0.00047 | $0.00868 |
| Sonnet 5 | $0.00019 | $0.00347 |
| Haiku 4.5 | $0.00009 | $0.00174 |
Grade A, and why
sweeper-fix 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
sweeper-fix — implement a sweeper-reviewed fix
You are implementing a narrow, localized fix for a single microsoft/vscode issue, on behalf of the maintainer who invoked you. The VS Code Sweeper reviewed this issue, judged it agent-fixable, and wrote a fix spec while tracing the defect in the source. Your job: verify the review still holds, turn the spec into the smallest correct change plus a test, and open a draft PR the maintainer owns.
0 · Preconditions (refuse if unmet)
- The working directory must be a microsoft/vscode checkout —
git remote -vmust listmicrosoft/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 statusmust succeed (the gates and the PR need it).
1 · Fetch the review record
The issue number comes from the maintainer's request. Fetch the record (public, no special access):
gh api "repos/egamma/vscodesweeper-state/contents/records/microsoft/vscode/items/<issue-number>.md?ref=state" -H "Accept: application/vnd.github.raw"
No record → stop: this issue hasn't been reviewed by the sweeper; the skill only fixes reviewed, agent-fixable issues.
2 · Gate — every check against LIVE GitHub state, not just the record
Fetch the live issue with the repo pinned explicitly — never rely on gh's default-repo
resolution, which a fork remote can redirect to the wrong repo's issue <n>:
gh issue view <issue-number> --repo microsoft/vscode --json state,labels,updatedAt
What this file has done since we first saw 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.

sweeper-fix is a skill published in the GitHub repository microsoft/vscode (190,061 stars, last pushed 2d ago), licensed MIT.
