Diagnose Harness pipeline executions via MCP. Analyzes any execution (failed or successful) to produce structured reports with stage/step breakdown, timing, bottlenecks, failure details, chained pipeline drill-down, and execution logs. Use when asked to debug a pipeline, investigate a failure, find out why a build failed, analyze pipeline errors, check execution logs, review execution performance, or find bottlenecks. Trigger phrases: debug pipeline, pipeline failed, why did my build fail, analyze failure, pipeline error, execution logs, fix pipeline, execution bottleneck, slow pipeline.

# Debug Pipeline

Diagnose pipeline executions and suggest fixes via MCP.

## Instructions

### Step 1: Diagnose Execution (Preferred)

Use the dedicated diagnosis tool. It accepts an execution_id, pipeline_id (auto-fetches latest execution), or a Harness URL:

```
Call MCP tool: harness_diagnose
Parameters:
  pipeline_id: "<pipeline_identifier>"   # or execution_id or url
