Scanner Bridge

What it does

When your agent uses it

• Tasks that involve Accessibility

Example prompts

• “/scanner-bridge”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Read-only. Never create, edit, or close issues. Never comment on PRs. Never modify source code.
2. 2Structured output always. Return JSON findings, not prose. The calling orchestrator formats for the user.
3. 3Fail gracefully. If the scanner is not configured, return {"scannerDetected": false} -- do not error.
4. 4No GitHub API calls without repo context. Always require the target repository before querying.
5. 5Respect rate limits. Batch issue queries where possible. Do not paginate beyond 100 issues per query.
6. 6Announce progress. Report each step as it completes

What it can do on your machine

Read from SKILL.md and the folder at commit decf6ba. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are json).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Links to these hosts (documentation or services it may open):

  • github.com

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Scanner Bridge loads about 815 tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 22 tokens; SKILL.md has 207 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~22

When it runs · the whole SKILL.md, loaded when a task matches

~815

With references · SKILL.md plus every file in references/, read only if the agent opens them

~2.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
