source-finder

source-finder is a skill for Claude Code, Codex from surfmind-space/awesome-surfmind. It costs 86 tokens per session (590 once invoked), scanned A, original, MIT.

A research assistant for finding reliable sources that support or challenge claims in text. It prefers original research, official records, standards, laws, and other authoritative material.

In plain words
What is it for?
Use it when you need evidence for a statement, want to check whether a citation really supports it, or need suitable sources for numbers, dates, names, or quotations.
Why use it?
It helps avoid citing sources that are too weak, outdated, general, or unrelated to the exact claim. It also points out claims that still cannot be verified.

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

source-finder 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 8d 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.

Source Finder

Find credible primary or authoritative sources that verify, challenge, or strengthen the claims in the selected or visible text. Never invent sources, URLs, titles, authors, or dates, present a summary or commentary as a primary source, or inflate a weak source into proof.

  1. Identify the specific claims or questions that need stronger sourcing, and note the numbers, dates, names, or quotes a source would have to match.
  2. Prefer primary, official, standards-body, academic, legal, regulatory, or original-data sources over summaries and commentary. Use web search or any browser/MCP tool available, and treat each result as evidence to inspect rather than automatic truth.
  3. Weigh each candidate for authority, recency, specificity, and whether it actually supports the exact claim, not just the general topic. Before citing a source, confirm it exists and says what you think — open the link or search the exact title or DOI — rather than trusting a recalled reference.
  4. Flag claims that need a source but can't be verified from the available context, and say what kind of source would settle them.

Report each claim with its best source candidates, why each one is stronger, what it actually supports, and any caveats or gaps. Preserve exact names, numbers, links, dates, and currencies, and don't cite a source unless it directly supports the claim.

Example

Source text: "Intermittent fasting boosts metabolism by 14%."

Claim: Intermittent fasting raises metabolic rate by 14%.

Best source candidates: A peer-reviewed metabolic-ward study in a journal such as The American Journal of Clinical Nutrition, or a systematic review of fasting and resting energy expenditure.

Why each is stronger: Both are primary or pooled measured data, not a press summary; the original study reports the actual measurement and the conditions behind a figure like "14%."

What it supports: Whether a metabolic change of that size was measured, in whom, and over what window — the specific 14% figure, not just "fasting affects metabolism."

Caveats or gaps: The visible text gives no citation, sample, or timeframe, so the 14% can't be traced yet. A single small trial wouldn't settle it; a systematic review would carry more weight.

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.
