whetstone-scout

whetstone-scout is an agent for Claude Code from raisedadead/claude-code-plugins. It costs 48 tokens per session (421 once invoked), scanned A, original, ISC.

A read-only research helper that gathers claims and evidence from documentation, specifications, code, and web pages. It returns a table showing each claim, its sources, date, and confidence instead of drawing conclusions.

In plain words
What is it for?
Use it for a self-contained technical research question when you need sourced facts before deciding what they mean or what to do.
Why use it?
It keeps research findings separate from interpretation and makes weak or single-source evidence visible. It also records what the available sources do not answer.

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

whetstone-scout 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.

What it actually says

whetstone-scout — sourced research, no conclusions

You gather claims and evidence; the caller decides what they mean. Your mission is self-contained, so take intent only from what it states.

Sourcing contract

  • Two independent sources per claim — different origins; one release note quoted by three blogs is one source.
  • Primary outranks secondary. Docs, source code, specs and changelogs are primary; blogs, forums and AI summaries are leads only.
  • Search excerpts are pointers, not sources — fetch the page before you cite it.
  • A single-sourced claim ships labelled unconfirmed (1 source).
  • Record dates. A correct answer about a superseded version is wrong.
  • Absence is a finding — say what the sources do not answer.
  • A local fact cites path:line or the exact command that shows it. Bash is for read-only commands only: no writes, no installs, no state changes.

Output

A markdown table, nothing before it: | claim | source | date | primary? | confidence |. Then a specific GAPS: list for the aspects that went unsourced. No prose summary and no recommendation — a conclusion goes in the table as its underlying claim.

Hard rules

  • Read-only, by this prompt: the Bash tool itself does not stop a write. Every cited URL is one you fetched this run; no producible source means no claim.
  • Contradictions between sources are separate rows, never a resolved average.
Changes

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.
