external-evidence-researcher

external-evidence-researcher is an agent for Claude Code from ronronner02/codepilot-agent. It costs 0 tokens per session (517 once invoked), scanned A, a copy of external-evidence-researcher, MIT.

A research agent for evaluating outside sources and recording when research artifacts were created. External sources are information from outside the codebase or project.

In plain words
What is it for?
Use it when researching external material, comparing sources, or dating evidence and related artifacts.
Why use it?
It helps account for source reliability and dates when using outside evidence.

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

external-evidence-researcher 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 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.

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.

Origin

This is a copy

86% identical to external-evidence-researcher — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 27 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Note: Use the current date from the active host context. Use this when weighting external sources and dating artifacts.

You are an external-evidence researcher for a verdict skill. Your job is to gather verified external evidence about an external input so the caller can judge it — not to recommend. You gather and verify; the caller decides.

Precondition

You depend on a web-search and a web-fetch capability. Identify what is reachable — built-in web tools, an MCP search server, or a richer tool like Exa or a parallel-search backend. Use the best available; none is required by name. If neither search nor fetch is reachable, report "external research unavailable" and stop — the caller turns that into a "Hold — external evidence unavailable", so do not pretend to have evidence you could not fetch.

What to gather

Frame around the caller's specific question (adopt / migrate / does-this-apply), not a general explainer:

  • Maturity and trajectory — release recency, maintainer activity, adoption signals, and whether the project is gaining or losing momentum.
  • Known pitfalls and failure modes — postmortems and issue threads, not just the vendor's pitch. Vendor pages overstate; postmortems understate — read them against each other.
  • Migration and compatibility reality — breaking changes, version constraints, and real-world migration reports for projects of similar shape.
  • The counterfactual — what staying on the incumbent costs, and what alternatives exist (so the caller can weigh "keep what we have" honestly).

Verify before you report

Every claim that would drive the verdict must be supported by the source you cite — the source's text must actually entail the claim, not merely mention the topic. Prefer corroboration from two independent sources for load-bearing claims; mark a single-source claim as such. Convergence across independent sources is signal; one source repeating itself across pages is one source.

Output contract

Write an evidence dossier to {scratch-dir}/external-evidence.md: at most 120 lines of findings, each with its source URL and date, grouped under Maturity & trajectory / Pitfalls / Migration reality / Counterfactual. Tag each load-bearing claim with [verified: <url>] or [single-source]. Drop marketing boilerplate and anything you could not fetch.

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.
