verificate-mcp-quickstart: Skill for Claude Code

.claude/skills/verificate/SKILL.md

verificate is a skill for Claude Code from VerificateAI/verificate-mcp-quickstart. It costs 92 tokens per session (656 once invoked), scanned B, original, MIT.

A read-only review process for checking AI-written code, plans, and documents before they are presented as complete.

In plain words
What is it for?
Use it to validate code, documentation, or plans before shipping, merging, or relying on them.
Why use it?
It detects placeholders, invented APIs, false claims of completion, and other problems that can make AI output unsafe to trust.

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 B, and why

verificate scanned grade B with 2 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 9d 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.

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

How it starts

The opening of the file, as written. The whole thing — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Verificate — verify AI-written work before you trust it

The merge gate for AI-written code, plans, and documents. Deterministic reality gates run first and can veto (no model output can override them); a frontier-model review then scores what survives. Read-only: code is analyzed, never executed.

When to use this skill

  • Before presenting a substantive code change as finished.
  • When the user asks to validate / review / verify / gate AI-generated code, a plan, or a document.
  • When a coding agent is about to accept a diff or write code to disk.

How to use it

Preferred — the MCP server (if connected): call validate_ai_output with the code and validation_type: "code_generation" (use "documentation" for prose, validate_plan for designs). Add the server once with:

claude mcp add --transport http verificate https://mcp.verificate.ai/mcp

Fallback — direct HTTP (no MCP client needed): POST a JSON-RPC tools/call to https://mcp.verificate.ai/mcp:

curl -s https://mcp.verificate.ai/mcp -H "content-type: application/json" -d '{
  "jsonrpc":"2.0","id":1,"method":"tools/call",
  "params":{"name":"validate_ai_output","arguments":{
    "ai_output":"<CODE HERE>","validation_type":"code_generation"}}}'

The response contains result.structuredContent with valid (approve/reject), score, and issues (the findings).

What to do with the verdict

  1. If valid is false (REJECTED), fix every finding and validate again. Never present rejected work or summarize the findings away — a deterministic-gate veto cannot be argued past; the flagged content itself must change.
  2. Tell the user, in one plain sentence, what the gate caught. A caught bug is exactly the outcome they want.

Free tier & privacy

25 validations per machine, no signup, no card, no token. After that, add Authorization: Bearer <token> (30-day trial at https://verificate.ai/auth/signup). Code is analyzed, never executed, never used to train models. Privacy: https://verificate.ai/privacy

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.

verificate is a skill published in the GitHub repository VerificateAI/verificate-mcp-quickstart (1 stars, last pushed 16d ago), licensed MIT. It adds 92 tokens to every session and 656 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
