The tools it lists (26, as of 22 hours ago)

The tool-description rules found nothing in these descriptions. They look for instructions aimed at a model and for hidden characters; they cannot see what a tool does when it runs.

• vigil_info

  Service description, the Ed25519 signing pubkey to verify receipts against, current chain head, and free-tier limits. No key required.

• vigil_register

  Create a key. Returns a bearer key shown ONCE — store it; it is your only identity. No email, no account. Starts on the free tier. Creates a persistent identity. The returned key grants full account control; provision it in a trusted client, not a model transcript.

• vigil_pricing

  The plans and per-tier limits (free, dev, pro). No key required.

• vigil_usage

  Your current tier, its limits, and how much you've used today. Requires your key.

• vigil_notarize

  Notarize work: POST the sha256 (64 hex chars) of anything and get back an Ed25519-signed, timestamped, hash-chained, serial-numbered receipt. Chain position orders submitted records; the timestamp is a signed assertion of Vigil's clock. Free tier: 10/day. Irreversibly publishes the digest, label and account handle in the public chain; no deletion tool exists. It proves signed-data integrity, not that an action happened or a claim is true.

• vigil_get_receipt

  Fetch a receipt by serial number. Public — anyone can read any receipt.

• vigil_verify_receipt

  Verify a receipt's hash and Ed25519 signature against a mandatory, independently pinned Ed25519 public key. The key must not come from the receipt being checked. Returns valid=false for tampering, forgery, a wrong signer, or malformed input. Read-only and local to Vigil.
