AI Evidence & Fact-Checking Suite
The complete pipeline for trustworthy AI content. Grade your sources, trace every claim back to its origin, catch hallucinated facts and unsupported technical claims, and gate high-stakes content before it ships. Four evidence skills that together take AI output from "sounds right" to "defensible" — built for high-stakes writing where a wrong claim is expensive. Save about 20% versus buying them separately.
Works with every agent that reads SKILL.md — Claude Code, Cursor, Codex CLI, Gemini CLI, GitHub Copilot, Windsurf, OpenClaw, and more.

What's included
4 skills
Runs an ordered evidence-integrity gate over any AI draft — grade sources, ground claims, verify technical assertions, stress-test — then returns one PASS/REVISE/FAIL ship decision.
A reusable rubric that grades every source by type, recency, authority, independence, and corroboration, then ranks them and resolves conflicts by evidence weight.
Audit any AI-generated output for unsupported claims, then verify every factual and technical assertion against its real source before it ships.
Audits any AI draft for unsupported claims — flags each one, grades its source, and returns a substantiation report.

You say
Run the evidence integrity gate on this release note before I publish it. DRAFT: "Our new API eliminates latency and guarantees 100% uptime. It supports Node 16 and is 3x faster than v1." SOURCES: docs/api-reference.md, package.json, bench/results.json.
Your agent does
=== EVIDENCE INTEGRITY GATE === Draft: release-note.md | Sources provided: 3 | Files checked: 3
VERDICT: FAIL
BLOCKING ISSUES (must fix before ship):
-
UNSUPPORTED: "guarantees 100% uptime" — no source supports this -> remove or qualify
-
CRITICAL: "supports Node 16" — package.json engines requires >=18.0.0 -> fix version claim
-
Stage 1 SOURCE LEDGER: 3 sources (2 RELY, 1 CORROBORATE, 0 AVOID)
-
Stage 2 SUBSTANTIATION: 4 claims (1 GROUNDED, 1 INFERRED, 0 WEAK, 1 UNSUPPORTED)
-
Stage 3 VERIFICATION: 1 CRITICAL, 1 WARNING ("3x faster" cites no benchmark) -> FAIL
-
Stage 4 STRESS TEST: Weakest point: "eliminates latency" overclaim -> REVISE
TOP 3 FIXES, RANKED:
- Correct the Node version to >=18 (CRITICAL mismatch).
- Remove the 100% uptime guarantee or cite an SLA.
- Soften "eliminates latency" to "reduces average latency" and cite bench/results.json for "3x faster."
