skill-optimizer

Optimize your skills and tiles: review SKILL.md quality, generate eval scenarios, run evals, compare across models, diagnose gaps, and re-run until scores improve.

tessl install tessl-labs/skill-optimizer

Concepts

This tile combines two complementary approaches to improving your skills:

• Tile evals (tessl eval run) — measure whether a tile makes agents better at real tasks. Scenarios are generated from the tile, an agent solves each task with and without the tile, and a judge scores outputs against a per-scenario rubric. The delta between baseline and with-tile scores shows the value-add.
• Skill reviews (tessl skill review) — assess the quality of a SKILL.md file itself, without executing any tasks. A judge scores the document on fixed dimensions (completeness, actionability, conciseness, robustness) to check whether it's well-structured for routing and agent comprehension.

The optimize-skill-performance-and-instructions skill combines both into a single end-to-end cycle: review → eval → improve.
