Context Cost

~1,121Tokens (tool definitions)
~1.1 KBTypical response size
Moderate attention impact (0.88% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (8)

🟢 Read-only🟡 Write🔴 Delete⚪ Unknown
⚪commit(committer, nonce, commit_hash, deadline, context)

Commit to a deliverable BEFORE handover. commit_hash = sha256(salt || sha256(content)) as 64 hex chars; deadline is ISO-8601; context links the escrow/job. Idempotent per (committer, nonce).

Input Schema

{
  "type": "object",
  "properties": {
    "committer": {
      "title": "Committer",
      "type": "string"
    },
    "nonce": {
      "title": "Nonce",
      "type": "string"
    },
    "commit_hash": {
      "title": "Commit Hash",
      "type": "string"
    },
    "deadline": {
      "title": "Deadline",
      "type": "string"
    },
    "context": {
      "default": "",
      "title": "Context",
      "type": "string"
    }
  },
  "required": [
    "committer",
    "nonce",
    "commit_hash",

      "type": "string"
    }
  },
  "required": [
    "result"
  ],
  "title": "commitOutput"
}
⚪reveal(commitment_id, salt, content_digest)

Reveal the committed content's digest + salt after handover. Verifies against the commitment (one bit of drift fails); returns a delivery_proof string for escrow release. Late reveals expire the commitment.

Input Schema

{
  "type": "object",
  "properties": {
    "commitment_id": {
      "title": "Commitment Id",
