Run Evaluation Skill

Perform a comprehensive post-mortem analysis of the latest Universal Agent run.

Workflow

Step 1: Identify the Latest Session

Find the most recent session directory:

ls -lt /home/kjdragan/lrepos/universal_agent/AGENT_RUN_WORKSPACES/ | grep session_ | head -1

Extract the session path (e.g., /home/kjdragan/lrepos/universal_agent/AGENT_RUN_WORKSPACES/session_20260115_094820).

Step 2: Read the Run Log

Load the full run log for context:

cat {session_dir}/run.log

This contains the complete terminal output including:

Tool calls and responses
Error messages
Timing information
Agent decisions

Step 3: Extract Key Metrics from run.log

Parse the log for:

Tool call count: Count occurrences of 🔧 [
Error indicators: Search for Error, Failed, Exception, ❌
Timing: Look at +Xs timestamps for latency
Retries/deduplication: Search for Idempotent, retry, deduped

Step 4: Query Logfire for Trace Analysis

Use the Logfire MCP tools to analyze the run. Get the trace_id from the run.log (appears near the top).

Key queries:

Find all exceptions in the run:

SELECT start_timestamp, span_name, exception_type, exception_message 
FROM records 
WHERE is_exception = true 
ORDER BY start_timestamp DESC

Find slowest operations:

SELECT span_name, duration, message 
FROM records 
WHERE duration IS NOT NULL 
ORDER BY duration DESC 
LIMIT 20

Find tool execution timeline:

SELECT start_timestamp, span_name, duration, message 
FROM records 
WHERE span_name LIKE '%tool%' OR message LIKE '%Tool%' 
ORDER BY start_timestamp

Find warnings and errors:

SELECT start_timestamp, message, level, exception_message 
FROM records 
WHERE level >= 30 
ORDER BY start_timestamp

Step 5: Analyze Session Artifacts

Check the session directory structure:

find {session_dir} -type f -name "*.md" -o -name "*.json" -o -name "*.html" | head -30

Verify expected outputs exist:

tasks/{task_name}/refined_corpus.md - Research corpus
work_products/*.html - Final report
search_results/ - Search result JSON files (may be archived)

Step 6: Generate Evaluation Report

Produce a structured report with these sections:

Evaluation Report Template

# Agent Run Evaluation Report

**Session:** {session_dir}
**Timestamp:** {datetime}
**Total Duration:** {total_time}

## Executive Summary
[1-2 sentence overall assessment]

## Metrics Overview
| Metric | Value | Status |
|--------|-------|--------|
| Total Tool Calls | X | ✅/⚠️/❌ |
| Exceptions | X | ✅/⚠️/❌ |
| Average Tool Latency | Xs | ✅/⚠️/❌ |
| Retries/Dedupes | X | ✅/⚠️/❌ |

## Happy Path Analysis
- [Did the agent follow the expected workflow?]
- [Were there any unexpected detours?]
- [Did sub-agents complete their tasks?]

## Exceptions & Errors
[List each exception with context and potential cause]

## Performance Bottlenecks
[List slowest operations and why they were slow]

## Opportunities for Improvement
1. [Specific actionable recommendation]
2. [Specific actionable recommendation]
3. [Specific actionable recommendation]

## Logfire Trace Links
- [Link to full trace in Logfire UI]

Evaluation Criteria

Happy Path Indicators (✅)
