TypeFox Agent Skills

A collection of agent skills for the open source technologies maintained at TypeFox.

Using Skills

Install skills with the skills CLI:

# Install all skills from this repo
npx skills add TypeFox/agent-skills

# Install a specific skill
npx skills add TypeFox/agent-skills -s <skill-name>

Skills are activated automatically when their trigger conditions match your conversation context. See the agent skills documentation for details on how skills work and how to manage them.

Writing Skills

Each skill lives in its own subfolder under skills/. To get started, install the skill-creator skill first:

npx skills add anthropics/skills -g -s skill-creator

Then use /skill-creator in your agent to scaffold, edit, and test skills interactively.

Evaluating Skills

To measure whether a skill actually improves agent output, use the skill-evals skill. It runs prompts with and without the skill, grades both against the same assertions, and writes a comprehensive report.

Install it (and skill-creator, which skill-evals depends on):

npx skills add TypeFox/agent-skills -g -s skill-evals

Then use /skill-evals in your agent to run the evaluation end-to-end. Use a relatively cheap model for this work; evals spawn many subagent runs and can consume a lot of tokens.

Results are written to a local workspace (gitignored) at skills/{skill-name}-workspace/iteration-{n}/REPORT.md. Review that report for the benchmark summary, per-test outcomes, and recommendations before iterating on SKILL.md or evals/evals.json.
