067-remote-trigger-tool: RemoteTriggerTool - Remote Webhook/API Trigger

A tool that triggers remote webhooks or API calls with support for various authentication methods, request/response handling, retry logic, and result validation.

At a glance

Reading this spec

This spec defines RemoteTriggerTool, a tool that fires remote webhooks and calls third-party APIs, so agents can integrate with external services, trigger automated workflows (such as a CI/CD pipeline), take part in event-driven architectures and chain multi-step API calls. It handles authentication, request and response processing, retries and result validation.

Three user stories give the scope: a CI/CD pipeline trigger, external service integration and multi-step API chaining. The design is an HTTP/HTTPS client with connection pooling, several authentication schemes (API key, bearer token, basic auth, OAuth2 and HMAC), request and response transformation, retry with exponential backoff, and webhook signature verification. The functional requirements (FR-001 onward) cover HTTP request execution, authentication support, request configuration, retry logic, response validation and timeout handling.

The 23 requirement IDs (REQ-067-NNN) pin down the details. Requests use GET, POST, PUT, PATCH, DELETE, HEAD or OPTIONS with configurable headers, body and query parameters. A numeric Retry-After response header sets the delay before the next attempt. Response validation uses a lightweight JSON Schema subset (type, required, properties and items). The connection pool is a configurable httpx.Limits pool scoped to one execute call. Logs record method, sanitized URL, status, elapsed time and retry count, and sensitive headers are sanitized in them. A public verify_signature method checks a payload against a signature, secret and algorithm.

The implementation is in the remote trigger tool module. The requirements traceability matrix lists each ID. The spec's own status line reads Complete and it tracks 3 files. Measured coverage is 23 of 23 requirements cited by at least one @traces in src/ (100.0%), spread over 1 module; the module citing the most of them is orchestrata_ultimate/tools/remote_trigger_tool (23 requirements). In tests/, 0 requirements are cited by a test-side @traces, so test-side citations are thinner than code-side ones.

Terminology

Core Concepts

• Webhook: HTTP callback sent to a specific URL when an event occurs
• API Call: Direct HTTP request to a RESTful or GraphQL endpoint
• Authentication: Mechanism to verify identity (API Key, Bearer, OAuth2, HMAC, Basic)
• Retry Logic: Automatic re-attempting of failed requests with exponential backoff
• Connection Pool: Reusable HTTP connections for performance optimization
• SSL/TLS Verification: Validation of server certificates for secure communication
• Webhook Signature: HMAC hash used to verify authenticity of webhook payloads
• Timeout: Maximum time to wait for response before aborting request
• Rate Limiting: API restriction on request frequency to prevent abuse

Key Components

• RemoteTriggerTool: Main tool class for executing remote triggers
• TriggerRequest: Configuration object for trigger execution
• TriggerResponse: Result object returned after trigger execution
