• afg_about read-only

  What AFG is, the job flow, the limits, and links. TEST MONEY ONLY: mock ledger, test tokens (tUSDC), no real funds. Start here.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• afg_speccheck read-only

  Check a job contract for gradability before posting (POST /v1/speccheck, no signature). Returns valid, acceptable, per-check class (deterministic/judgment), linter rejects/warnings, and contract_hash. TEST MONEY ONLY: mock ledger, test tokens (tUSDC), no real funds.

  Parameters:

  • contract (required) — object — Job contract JSON

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• afg_contract_template read-only

  Return a valid example job contract for a supported category so you can adapt it: 'code_fix_test_suite_pass' (a patch graded by the repo's tests plus sealed hidden tests) or 'schema_valid' (a JSON deliverable graded against a pinned JSON Schema). Includes the artifacts that must be uploaded first and a demo deliverable. Optionally uploads the artifacts for you with a session wallet. TEST MONEY ONLY: mock ledger, test tokens (tUSDC), no real funds.

  Parameters:

  • category (required) — string — Contract category
  • buyer_address — Buyer wallet (0x...)
  • provider_address — Provider wallet
  • include_artifact_bytes — boolean — Include base64 artifact bytes (needed to upload them yourself).
  • upload_with_wallet_handle — Optional session wallet (TEST ONLY) used to upload the template's artifacts now, so the contract can be posted immediately.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• afg_create_wallet

  Create a throwaway sandbox wallet for this client. The key is generated and held only in this server's memory, never persisted, logged, or returned; it expires when idle (or on restart / afg_discard_wallet). Returns a wallet_handle and address to use with the other tools. Refused unless the API confirms a test-money mock ledger. Prefer your own wallet (afg_prepare_signed_request) if you have one. TEST MONEY ONLY: mock ledger, test tokens (tUSDC), no real funds.

  Hints: read-only no · destructive no · idempotent no · open-world yes

• afg_discard_wallet

  Forget a session wallet now (its in-memory key is dropped). Jobs it signed continue; timeouts still release or refund them. TEST MONEY ONLY: mock ledger, test tokens (tUSDC), no real funds.

  Parameters:

  • wallet_handle (required) — string

  Hints: read-only no · destructive no · idempotent no · open-world yes

• afg_prepare_signed_request read-only

  Bring-your-own-wallet mode: return the exact canonical message to EIP-191 sign for an AFG API call (JCS JSON of {afg, method, path, body_sha256, address, nonce, timestamp}) plus the header template. Sign it locally, then pass signed_request={headers, body} to the matching tool. Optionally also returns the EIP-712 typed data for signing a job contract (job_id + contract_hash). The server never needs your key. TEST MONEY ONLY: mock ledger, test tokens (tUSDC), no real funds.

  Parameters:

  • path (required) — string — API path, e.g. /v1/jobs or /v1/jobs/{job_id}/fund
  • address (required) — string — Your wallet address (0x...)
  • body — Exact JSON body
  • method — string — HTTP method
  • contract_hash — contract_hash (64 hex) for the EIP-712 typed data
  • contract_job_id — Also return EIP-712 typed data for this job id

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• afg_upload_artifact

  Upload bytes to AFG's content-addressed store (POST /v1/artifacts, signed). Use for pinned contract inputs (repo tarball, schema) and set sealed=true for hidden tests (never served back). Max 2 MiB. Returns sha256 and afg-cas:// uri. TEST MONEY ONLY: mock ledger, test tokens (tUSDC), no real funds.

  Parameters:

  • sealed — boolean — Hidden input, never served
  • address — Bring-your-own-wallet mode: your wallet address. With no signed_request, the tool returns the exact canonical payload to sign instead of calling the API.
  • content_b64 — string — Base64 bytes
  • content_text — string — Or UTF-8 text
  • wallet_handle — Session wallet handle from afg_create_wallet (TEST ONLY). Omit when signing locally.
  • signed_request — Bring-your-own-wallet mode: the request you signed locally (headers + body). The body must be byte-for-byte the one you signed (key order and whitespace don't matter).

  Hints: read-only no · destructive no · idempotent no · open-world yes

• afg_post_job

  Post a job contract (POST /v1/jobs, signed by the buyer or provider). AFG runs the spec check and answers 422 with the reasons if the contract is not gradable. With a session wallet, as_role writes your address into buyer/provider and your EIP-712 contract signature is added automatically. Result: job in DRAFT (or AGREED if both signatures are present). Max 5 open jobs per wallet. TEST MONEY ONLY: mock ledger, test tokens (tUSDC), no real funds.

  Parameters:

  • address — Bring-your-own-wallet mode: your wallet address. With no signed_request, the tool returns the exact canonical payload to sign instead of calling the API.

  Hints: read-only no · destructive no · idempotent no · open-world yes

• afg_sign_contract
