verify

verify is a command for coding agents from AURORA-NEURO/aurora-agent. It costs 18 tokens per session (243 once invoked), scanned A, original, Apache-2.0.

A command that checks the digest of a FIBER context certificate by recomputing its canonical hash. This confirms whether the certificate's contents match the value it records.

In plain words
What is it for?
Use it to verify a certificate file, report whether its digest matches, and check its schema version.
Why use it?
It lets you check a certificate without needing the engine that originally created it.

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.

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

verify 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 4d 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

Verify a context certificate.

  1. Resolve the aurora-agent checkout ($AURORA_AGENT_ROOT~/aurora-agent~/bioprism); CLI at <root>/target/release/bioprism(.exe).
  2. $ARGUMENTS must name a certificate JSON path (relative to the root). If none was given, ask which certificate to verify — or compile one first with context compile --certificate-out <path>.
  3. Run from the checkout root: bioprism --json context verify --certificate <path>
  4. Report the verification string verbatim ("digest verifies" or the failure text) plus the schema version. Exit 0 = the digest verifies; exit 1 = assertion_failed is the honest "it does not verify" verdict, not a tool error. Certificates are verifiable without the engine that produced them — that independence is the design point worth mentioning when relevant.
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.
