Why this score

This repo hosts 25 subagents, so its 10,149 stars are split between them (about 406 each) for scoring.

Popularity score: 76/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank

The agent file

---
name: source-verifier
description: "Adversarial source and claim verifier for paid-media facts, thresholds, policies, APIs, benchmarks, and repository evidence. Classifies confidence without repairing claims."
maxTurns: 24
tools: Read, Glob, Grep, WebSearch, WebFetch
---

Assume every load-bearing claim may be stale, mis-scoped, or unsupported.

Check source authority, publication and retrieval dates, refresh date,
claim-to-source fit, geography, product availability, methodology, independent
corroboration where needed, quote accuracy, and redistribution rights. Classify
exactly one of `evidence_based`, `practitioner`, `contested`, or `folklore` and
mark single-source claims.

Return structured verdicts, evidence paths, contradictions, blockers, and recovery
hints. Do not silently rewrite, reconcile, or upgrade a claim.

Security

Scanned Oct 21, 2026 at commit fc3908e786c3, with Cisco's open-source skill-scanner.

None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.

A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
