OpenClaw Agreement Sender

Send client agreements for signature by detecting signature blocks with NanoPDF and placing DocuSign tabs automatically. Use when a user needs an OpenClaw workflow to ingest a PDF agreement, find signature coordinates, map signers, and dispatch a DocuSign envelope without manual tab placement.

OpenClaw DocuSign Agreements

Use this skill to automate agreement sending in OpenClaw with NanoPDF block detection and DocuSign envelope creation.

Workflow

1. Confirm Inputs

Collect:

• Agreement PDF path
• Client signer list (name, email, optional key and routing_order)
• Email subject and optional message

Use references/nano-pdf-signature-schema.md for expected NanoPDF output and references/docusign-envelope-mapping.md for signer/tab rules.

2. Configure Environment

Set required variables:

• NANOPDF_BASE_URL
• NANOPDF_API_KEY
• DOCUSIGN_BASE_URL (for example https://demo.docusign.net)
• DOCUSIGN_ACCOUNT_ID
• DOCUSIGN_ACCESS_TOKEN

Optional:

• NANOPDF_DETECT_PATH (default: /v1/signature-blocks)
• DOCUSIGN_ENVELOPE_SUBJECT
• DOCUSIGN_ENVELOPE_BODY

3. Detect Blocks + Send Envelope

Run:

python3 scripts/send_agreement.py \
  --pdf contracts/nda.pdf \
  --signers-json contracts/signers.json \
  --output-dir output/openclaw-agreements

Optional flags:

• --subject overrides DOCUSIGN_ENVELOPE_SUBJECT
• --message sets the email blurb
• --status created saves as draft (sent is default)
• --scale 1.333333 converts NanoPDF point coordinates to DocuSign pixel-style positions

The script will:

• Call NanoPDF to find signature blocks
• Map each block to a signer (by signer_key first, then in signer order)
• Create signer tabs in DocuSign at detected coordinates
• Create and optionally send the envelope
• Write audit files in --output-dir

4. Validate Before Delivery

Check generated files:

• nanopdf_blocks.json
• docusign_payload.json
• envelope_result.json

If signer mapping is ambiguous or a signer has no blocks, stop and ask for explicit mapping before sending.

Safety Rules

• Never guess recipient emails.
• Stop on missing signature blocks unless the user explicitly approves manual fallback.
• Use --status created first for new templates or high-stakes contracts.
• Keep API tokens in environment variables only.
