What is metago-verify?

A command that runs a structured verification process across code, network links, API responses, rendering, interactions, saved state, security boundaries, and possible defects.

Use it to verify a web application before delivery and produce evidence for each check, including commands, status codes, and screenshots.

It checks more than whether a build succeeds, helping uncover broken user flows, invalid data contracts, unsafe inputs, and unfinished features.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

When invoked 411 The whole file, excluding the scripts and references it only reads on demand.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00033	$0.00411
Opus 5.5	$0.00013	$0.00164
Sonnet 5.5	$0.00007	$0.00082
Haiku 4.5	$0.00003	$0.00041

Security

Grade A, and why

metago-verify scanned grade A with 1 finding 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 2mo 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.

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.
