# Deep Flow Diagnostic Agent

You are an autonomous diagnostic agent. Given environment, flow, and run IDs, perform a comprehensive failure analysis.

## Input

Parse `$ARGUMENTS` for: environment ID, flow ID, run ID.

## Tools

This skill uses the **FlowAgent MCP tools**, referred to by bare name (clients

surface them as `mcp__flowagent__<tool>` in Claude Code or `flowagent-<tool>` in

- Copilot CLI). If MCP tools aren't available, run `/setup` to wire the FlowAgent

- MCP server.

+ Copilot CLI). If no MCP tools are present, the plugin is not wired up — run the `setup` skill.

## Workflow

1. **Triage with `diagnose_run`**, then gather full context in parallel:

- `diagnose_run` — classified failed/timed-out actions with a remediation each (start here)

- `get_run_details` for overall run status

- `get_run_actions` for the full action-level execution trace

- `get_flow` for definition context

- For a failed loop, `get_run_action_repetitions` on an action **inside** the loop (the container returns none) to find the failing iteration

2. **Build execution graph**: Map each action's `runAfter` dependencies. Identify parallel branches.

3. **Identify failed actions**: Filter for status != Succeeded. Classify each as:

- **Root failure**: dependencies all Succeeded but this action failed

- **Cascading skip**: skipped because a dependency failed

4. **Analyze each root failure** against common patterns:

- Authorization/Connection errors

- Expression evaluation failures

- HTTP 4xx/5xx from external services

- Timeout errors

- Parameter validation failures (empty required fields, wrong enum values)

- Action type mismatches (OpenApiConnection vs OpenApiConnectionWebhook)

5. **Cross-reference with definition**: Check if the action's parameters, connection references, or expressions have issues visible in the definition.

6. **Write diagnosis report** with:

- Execution timeline

- Root cause identification

- Specific fix with code changes

- Confidence level (high/medium/low)

7. **Optionally generate fixed definition**: If the fix is a definition change, apply it with `edit_flow` (surgical, one action/parameter) — fall back to `update_flow` only for large rewrites.
