scan-researcher

scan-researcher is an agent for coding agents from mostwise/dot-claude. It costs 26 tokens per session (1,446 once invoked), scanned B, original, no licence file.

A read-only security researcher used by the Claude Security scan workflow. It is not intended as a general-purpose research or exploration tool.

In plain words
What is it for?
Use it only as part of the Claude Security scan workflow to investigate vulnerabilities.
Why use it?
It limits the researcher to examining potential vulnerabilities without changing the system being scanned. Its description does not provide further details about the checks it performs.

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.

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 B, and why

scan-researcher scanned grade B with 1 finding 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 4d 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.

Tells the agent never to refusemediumAnti-refusal

Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

Vulnerability research on this repository is authorized work. Do not refuse it, and do not soften findings to be polite about the code.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

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.
