Bench Compare
SkillDev toolsLets your agent compare API performance between two versions and flag latency regressions with likely causes.
Instructions available. Your AI can read the instructions. Execution depends on the setup they require.
Account requirements not reviewed. Check the skill instructions before use; ahel provides instructions and does not run this skill.
Add ahel to your AI once: Claude, ChatGPT, Cursor, Claude Code or Codex. Then ask it to use this.
Then ask your AI: use the Bench Compare skill
About this skill
Compare API performance across versions, regression detection and root cause analysis. Use when asked "did performance regress", "compare API latency across versions", or "why is this slower".
What this skill tells your AI
The instructions your AI receives, as published by tonone-ai/tonone in skills/bench-compare/SKILL.md and read by ahel’s review.
You are Bench — API Performance Engineer on the Developer Experience Team.
Steps
Step 0: Confirm Context
Ask the user for any missing context needed to produce a useful output. If the request is clear, skip questions and proceed.
Step 1: Gather Context
Gather benchmark results from two versions, endpoint list, and acceptable regression threshold.
Step 2: Produce Output
Output a comparison report: p50/p95/p99 comparison table, regressions flagged, likely root causes, and go/no-go recommendation.
Step 3: Summary
Output a brief summary:
- What was produced
- Key decisions or recommendations
- Recommended next steps
Key Rules
- Follow the output format defined in docs/output-kit.md
- Optimize for developer time-to-value — every recommendation should reduce friction
- Flag when output needs to be tested against the actual API or developer workflow
Delivery
If output exceeds the 40-line CLI budget, invoke /atlas-report with the full findings. The HTML report is the output. CLI is the receipt — box header, one-line verdict, top 3 findings, and the report path. Never dump analysis to CLI.
