Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| relay_models_list | List available AI models with capabilities and pricing. Use to check valid model IDs before testing. Cost shows provider pricing (OpenAI/Anthropic) - RelayPlane is BYOK, we don't charge for API usage. |
| relay_run | Execute a single AI model call. Useful for testing prompts before building full workflows. Returns output, token usage, estimated provider cost, and trace URL. Note: Cost tracks your provider bill (OpenAI/Anthropic), not RelayPlane fees - we're BYOK. |
| relay_workflow_run | Execute a multi-step AI workflow. Intermediate results stay in the workflow engine (not your context), providing 90%+ context reduction on complex pipelines. Use for any task requiring multiple model calls or tool integrations. Cost tracks your provider bills, not RelayPlane fees - we're BYOK. |
| relay_workflow_validate | Validate workflow structure without making any LLM calls (free). Checks DAG structure (no cycles), dependency references, and model ID format. Does NOT validate schema compatibility between steps or prompt effectiveness - use relay_workflow_run for full validation. |
| relay_skills_list | List available pre-built workflow skills. Skills are reusable patterns for common tasks (invoice processing, content pipelines, etc.). Returns skill names, descriptions, context reduction metrics, and usage examples. |
| relay_runs_list | List recent workflow runs for debugging and reference. |
| relay_run_get | Get full details of a specific run including all step outputs and trace URL. |
