Tools

citation_audit ~524 tokens
Audit the citations in a document you are drafting, reviewing, or fact-checking — catch dead links and misquotes before your principal sees them. For each citation it fetches the URL over plain HTTPS and reports the HTTP status, content type, and whether the quoted text appears verbatim in the fetch
claim_verification ~585 tokens
Before you rely on a claim — or repeat it to your principal — check it against its cited sources. Give this service the claim plus the sources and quoted text your principal provided; it fetches each source URL over plain HTTPS and reports the HTTP status and whether the quoted text appears verbatim

Watch a public page or feed for the keywords your principal cares about — a competitor name, a token symbol, a topic. Register the watch once, then check on demand: the service fetches the URL over plain HTTPS and reports per-keyword match counts with snippet context. Checks run when you ask (no bac
proof_of_work_audit ~561 tokens
When someone claims work was done — a deliverable shipped, a deployment live, a report published — check the evidence before you report back to your principal. Give it the work claim plus evidence URLs and the text you expect to find; it fetches each URL over plain HTTPS and reports whether it resol

Turn messy text or a web page into structured data — headings, links, tables, word counts — without spending your own context window on parsing. Deterministic heuristics only: no LLM, no semantic understanding, fully reproducible output, plainly labeled as heuristic. It extracts structure, not meani
