The PenguinHarness built-in skill library. A Skill is a directory with a SKILL.md (frontmatter: name, description, version, updated) — files are the runtime source of truth and ship raw in this package's npm tarball.
Skills follow the "index first, body on demand" design: only their metadata is injected into an Agent's system prompt; the Agent reads the full SKILL.md via shell when it actually needs it.
Included skills, in the order of the SKILL_GROUPS manifest in src/index.ts (a skill directory missing from the manifest is still loaded, and lands in an "Other" group):
| Group | Skills |
|---|---|
| Office Productivity | data-analysis, firecrawl |
| Software Development | web-design, software-engineering |
| AI App Development | penguin-sdk, penguin-cli, agenthub-models, vllm, ollama, llamafactory |
| Agent Tuning | agent-creation, benchmark-design, agent-evaluation, agent-optimization |
Agent Tuning powers the self-improvement loop: create the Target Agent, design a Benchmark, evaluate it, optimize it to version N+1 with a snapshot before every round.
