verifier

verifier is an agent for Claude Code from orin-dx/agent-plugins. It costs 188 tokens per session (950 once invoked), scanned A, original, MIT.

A specification checker that compares a draft software specification with the requirements and research used to create it. It checks whether each criterion is supported by the source material.

In plain words
What is it for?
Verifying a draft specification and marking criteria as unsupported when they lack direct evidence in the supplied sources.
Why use it?
It prevents plausible-sounding requirements from being treated as facts when the original artifacts do not justify them.

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

verifier 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 1mo 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.

What it actually says

reasoning is scratchpad — never forwarded downstream.

WHEN a criterion appears plausible but lacks a direct citation from source artifacts, THE SYSTEM SHALL classify it as unsupported rather than infer justification.

Changes

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.
