Envelope Sender

Use this skill to send a single local PDF document for signature with eSignGlobal through an external CLI.

Installation

Use the external CLI through npx:

npx @esignglobal/envelope-cli <command>

Setup

Before calling any send action, set ESIGNGLOBAL_APIKEY in the shell environment.

# Windows PowerShell
$env:ESIGNGLOBAL_APIKEY="your_api_key"

# macOS / Linux
export ESIGNGLOBAL_APIKEY="your_api_key"

# Verify connectivity
npx @esignglobal/envelope-cli config health

Credential handling rules:

• The CLI reads credentials only from ESIGNGLOBAL_APIKEY
• Do not implement local credential storage inside this skill
• Do not print or persist secrets

Workflow

1. Collect a single absolute filePath, signer list, and optional subject
2. Confirm the file is a .pdf and the signer data is complete
3. Set ESIGNGLOBAL_APIKEY in the current shell session
4. Run the external CLI command to send the envelope
5. Return the CLI result to the user

Safety Rules

• Only use a file path the user explicitly provided for this task
• Only handle one local PDF file per run
• Refuse relative paths; require an absolute path to a .pdf file
• Reject any non-PDF file before invoking the CLI
• Never print or persist secrets
• Do not scan directories, expand globs, or discover files on the user's behalf
• Only call the trusted eSignGlobal CLI configured for this environment

Required Inputs

• filePath: absolute path to an existing local PDF file
• signers: JSON array of signer objects
• subject: optional email or envelope subject

Each signer must include:

• userName
• userEmail

Optional field:

• signOrder as an integer >= 1

Input Format

filePath

filePath must be an absolute path to an existing local PDF file.

Example:

/tmp/contract.pdf

signers

Each signer must include:

• userName
• userEmail

Optional field:

• signOrder (integer, minimum 1)

Single signer example:

[
  {
    "userName": "Bob Smith",
    "userEmail": "bob@example.com"
  }
]

Sequential signing example:

[
  {
    "userName": "Bob Smith",
    "userEmail": "bob@example.com",
    "signOrder": 1
  },
  {
    "userName": "Alice Jones",
    "userEmail": "alice@example.com",
    "signOrder": 2
  }
]

Parallel signing example:

[
  {
    "userName": "Bob Smith",
    "userEmail": "bob@example.com",
    "signOrder": 1
  },
  {
    "userName": "Alice Jones",
    "userEmail": "alice@example.com",
    "signOrder": 1
  }
]

External CLI Pattern

Use the external command-line tool instead of bundled scripts:

npx @esignglobal/envelope-cli send-envelope --file <filePath> --signers '<signersJson>' [--subject <subject>] --confirm

Check available commands if needed:

npx @esignglobal/envelope-cli help

Example:

npx @esignglobal/envelope-cli send-envelope --file "C:\\docs\\contract.pdf" --signers '[{"userName":"Bob Smith","userEmail":"bob@example.com"}]' --subject "Please sign this contract" --confirm

Required Configuration

• Node.js 18 or later
• Access to the trusted external CLI, either preinstalled or available through npx
• ESIGNGLOBAL_APIKEY must already be configured in the shell environment

Output

Return the external CLI result. Do not bundle or implement upload logic inside this skill.
