Operations

Create Session

Start a governance session that groups related agent tool calls.

Field Type Description
Agent ID string Unique identifier for the agent (e.g. email-agent)
Metadata JSON Optional context stored with the session

Output: session_id, agent_id, created_at

Intercept Tool Call

Intercept an agent tool call for policy evaluation and evidence sealing.

Field Type Description
Session ID string From Create Session output
Agent ID string Must match Create Session
Tool Name dropdown send_email, query_database, call_api, write_file, execute_code, send_slack_message
Tool Input JSON Parameters the agent wants to pass to the tool
Return Raw Response boolean Include full API response under _raw key

Output: decision (proceed / block / require_approval), reason, envelope_id, session_id, policy_set_name, mission_id

Get Session Timeline

Retrieve the full audit trail for a session.

Field Type Description
Session ID string Session to retrieve

Output: Full session object with all intercept events and envelope IDs.

Example Workflow

Create Session --> Intercept Tool Call --> Switch ({{ $json.decision }})
                                              |
                                    +---------+---------+
                                    |         |         |
                                 ALLOWED   BLOCKED   PENDING
                                    |         |      APPROVAL
                                 (execute  (abort,    (queue
                                  tool)    log it)   for review)
  1. Create Session -- start a governance session for your agent
  2. Intercept Tool Call -- ask Missionize before executing any tool
  3. Switch on {{ $json.decision }} -- route to ALLOWED, BLOCKED, or PENDING APPROVAL branches
  4. Each branch handles the outcome: execute the tool, abort, or queue for human review

Every decision is sealed in a cryptographic evidence envelope that can be verified offline.
