agenttrace Session Audit

Overview

Use this skill to inspect local AI coding-agent sessions with agenttrace. It focuses on the process behind a run: token and cost spikes, tool failures, retry loops, latency gaps, anomalies, health scores, and session-to-session diffs.

agenttrace is local-first and reads session logs from tools such as Claude Code, Codex CLI, Gemini CLI, Aider, Cursor exports, OpenCode, Qwen Code, Kimi, and generic JSON or JSONL traces.

When to Use This Skill

• Use when a user asks why an AI coding run was slow, expensive, shallow, or unreliable.
• Use when reviewing local agent logs before retrying a failed or suspicious task.
• Use when building a lightweight CI health gate for AI-assisted coding sessions.
• Use when comparing two attempts and looking for changed tool paths, retries, or cost patterns.

How It Works

Step 1: Discover Available Sessions

Prefer an installed agenttrace binary when it is available on PATH. If the current repository is luoyuctl/agenttrace, use go run ./cmd/agenttrace instead.

agenttrace --doctor
agenttrace --overview

If no sessions are detected, report the directories checked by --doctor and ask for the exported session file or log directory.

Step 2: Produce a Human-Readable Audit

Use Markdown when the user wants a concise report they can inspect or share.

agenttrace --overview -f markdown -o agenttrace-overview.md

In the report, lead with the highest-risk sessions and explain why they matter: critical anomalies, repeated tool failures, token or cost waste, long latency gaps, low health scores, and suspiciously shallow sessions.

Step 3: Inspect One Session or Directory

Use the latest session for a quick check, or pass an explicit export path when the user provides one.

agenttrace --latest
agenttrace --latest -f json
agenttrace path/to/session-or-export.json
agenttrace --overview -d path/to/session-dir

Step 4: Compare Attempts When Semantics Matter

Token and latency metrics can look healthy even when an agent confidently takes the wrong implementation path. When the risk is semantic drift, pair the trace audit with a diff against a previous or known-good attempt.

Look for:

• changed files or commands that diverge from the intended task
• missing tests or verification steps compared with the reference attempt
• repeated edits around the same files without a clear reason
• lower cost that came from skipping necessary exploration

Step 5: Add Automation Gates

For CI or repeatable team workflows, use JSON output or health thresholds.

agenttrace --overview -f json -o agenttrace-overview.json
agenttrace --overview --fail-under-health 80 --fail-on-critical --max-tool-fail-rate 15

Tune thresholds to the project. A strict gate is useful for critical workflows; a reporting-only command is better while the team is learning its baseline.

Examples

Quick Local Review

agenttrace --overview
agenttrace --latest

Use this after a long coding-agent run to decide whether the next prompt should split the task, avoid a failing tool path, add missing tests, or reset context.

CI Health Check

agenttrace --overview --fail-under-health 80 --fail-on-critical

Use this when agent session logs are available in CI and the team wants a simple guard against critical anomalies or unhealthy runs.

Best Practices

• Start with --doctor when session discovery is uncertain.
• Report missing fields plainly; do not invent cost, model, latency, or health data.
• Treat prompts, code, and session contents as private local data.
• Prefer JSON output for automation and Markdown output for human review.
• Use trace metrics for process failures and diff/reference review for semantic drift.

Limitations

• agenttrace can only analyze logs that are present locally or provided as exports.
• Some agents do not expose enough fields to infer cost, model, cache use, or latency.
• Healthy trace metrics do not prove the final code is correct; still run tests and review diffs.
• CI gates should start as advisory until the team understands normal baseline behavior.

Security & Safety Notes

• Do not upload private session logs to external services unless the user explicitly approves it.
• Do not overwrite user reports unless they requested that exact output path.
• Avoid printing secrets found in p
