Developers

Wrap the tools that act, run your agent once, then verify. Python and TypeScript, or let your coding agent add it for you.

What to know

  • Local first

    Records are signed and chained in .signafaide/ on your machine. Nothing is sent until you run signafaide init, which creates a free sandbox with no account. Only hashes are sent.

  • Nothing waits for the network

    Records are signed locally and sent in the background. If the service cannot be reached they wait on disk.

  • Hash only by default

    Inputs and outputs stay in .signafaide/ in your project, and each content hash is salted, so the hash does not reveal them. Turn on store_content to keep them with the service, encrypted.

  • Strict mode

    For actions that must never run unrecorded: the tool runs only after the service returns its receipt.

Python

# 1. Install
uv add signafaide    # or: python3 -m venv .venv && .venv/bin/python -m pip install signafaide

# 2. Wrap the tools that act
import signafaide

@signafaide.record
def approve_payout(claim_id: str, amount: float): ...

@signafaide.record(strict=True)
def wire_funds(account: str, amount: float): ...

# 3. Run your agent once, then verify
signafaide verify

# 4. When you choose, send hashes to a witness
signafaide init

TypeScript

# 1. Install
npm install signafaide

// 2. Wrap the tools that act
import { record } from "signafaide";

const approvePayout = record(async (claimId: string, amount: number) => {
  /* your code */
}, { name: "approve_payout" });

# 3. Run your agent once, then verify
npx signafaide verify

# 4. When you choose, send hashes to a witness
npx signafaide init

Coding agent

# 1. Give your coding agent the signafAIde MCP server and skill
npx signafaide agent setup

# 2. Ask it
"Record the tools in this project that make decisions."

# 3. It adds the SDK, wraps the tools and runs
signafaide verify
