Skills & Prompt Library
Two small libraries of reusable text: skills are focused playbooks composed into an agent's system prompt at run time; prompts are complete starter system prompts. Both exist so good instructions get written once and reused everywhere.
Skill Library
Skills at /skills follow the Anthropic-style skill.md pattern: a skill is a focused, reusable playbook — "how to write a structured code review", "how to cite sources from a knowledge base" — that you attach to any agent or swarm node. At run time every selected skill is composed into the agent's effective system prompt, so the same agent can be specialized for different jobs just by swapping skills.
- My skills — skills you write yourself in the editor, or generate with AI from a plain-English description and then edit.
- Sample skills — a curated set you can copy into your own library with one click and adapt.
- Attaching — open an agent in the Agent Builder (or a swarm node inspector) and select skills from the picker. Deleting a skill is safe: agents that referenced it simply drop it.
Prompt Library
The Prompt Library at /prompts is a searchable collection of complete system prompts, filtered by category — support, sales, engineering, research, data, writing, creative, operations, productivity, and education. Each entry has a preview so you can read the full prompt before using it, and you can save your own prompts to the library for reuse across agents.
Prompt Compare
/prompt-compare answers the most practical question in prompt engineering: given this exact prompt, how do different models behave? It runs the same prompt against two or three models side by side, streaming the outputs next to each other with per-panel latency, token counts, and real cost. Preset experiments are included — constraint-following, JSON-only output, and similar discriminating tasks — each with a note on what to watch for.
