skill-lens
An Agent Skill for writing, running and auditing skill-lens eval suites.
skill-lens turns "I think this SKILL.md got better" into a score, a report and an exit
code a CI pipeline can gate on. It cannot tell you which cases a skill needs, or what a
failing case means. This plugin carries that judgment.
What it contains
| Skill | What it does |
|---|---|
writing-skill-evals | Reads a skill's SKILL.md for its claims, proposes a list of cases and confirms it with you, then writes, runs and triages the eval suite. For each failing case it names the cause: the eval is wrong, the skill is wrong, or the setup is. It also audits a suite you already have. |
That one skill is the whole plugin: no commands, agents, hooks or MCP servers.
Requirements
The skill runs the skill-lens command-line tool, which this plugin does not install. See
