Skill Enhancement
Stop guessing whether your skills work. Benchmark every skill against real tasks, measure the ROI, and get automatically upgraded versions that perform better with fewer tokens.
Performance Score
Pass rate across held-out test queries — measures how reliably a skill triggers correctly and produces the right output. Higher is better.
Token Savings
Reduction in token usage per skill invocation after optimization. Directly translates to lower API costs and faster execution times.
Without vs. With Skill Enhancement
Most teams have no idea if their skills actually improve outcomes. Evaluation changes that.
No way to know if a skill actually helps
Every skill has a measurable performance score
Skills degrade silently over time
Continuous benchmarking catches regressions early
Manual trial-and-error to improve prompts
Automated optimization loop finds the best version
Token costs grow unchecked as skills expand
Token savings measured and optimized per skill
How It Works
A four-stage pipeline that benchmarks skills, measures ROI, and deploys upgraded versions automatically.
01
Generate Eval Queries
Realistic test prompts are generated — a mix of should-trigger and should-not-trigger cases. Edge cases and near-misses are prioritized over obvious matches to ensure rigorous evaluation.
20 eval queries generated: 10 should-trigger, 10 near-miss negatives
02
Run Benchmark Iterations
Each skill is tested with and without modifications across multiple iterations. Performance is measured on both training and held-out test sets to prevent overfitting.
Iteration 3/5 — train accuracy: 94%, test accuracy: 91% (+12% vs baseline)
03
Measure ROI
Every iteration produces concrete metrics: performance score improvements, token savings per invocation, and pass-rate deltas. No guesswork — just data.
Performance: +18% pass rate | Tokens: 2,340 → 1,870 (−20% savings)
04
Upgrade Automatically
The best-performing version is selected by test score (not train score) to avoid overfitting, then automatically applied. Your skill is upgraded with zero manual effort.
Best version selected from iteration 4 — deployed with 91% test accuracy
