Stdlib skills¶
Bundled skills shipped with reyn. Resolved last in name lookup (after reyn/project/ and reyn/local/).
| Skill | Purpose |
|---|---|
| skill_builder | Generate a new skill from a natural-language description |
| skill_improver | Iteratively improve a skill against an eval spec |
| skill_importer | Import an external skill (e.g. Claude skill) into reyn |
| eval | Evaluate one test case using LLM-as-judge |
| eval_builder | Generate an eval spec (eval.md) for a skill |
| skill_router | Route a chat utterance to a skill, peer agent, or direct reply (used by reyn chat). Reads + writes memory inline. |
| chat_compactor | Compact a long chat history into a structured rolling summary. Spawned automatically by reyn chat when token thresholds trigger; not directly invokable. |
Note: the previous
skill_narratorstdlib skill was removed in FP-0011 (2026-05-10). The router LLM now narrates skill completions inline as part of its post-invoke_skillturn — see the router system prompt's "spawn-ack + completion-narration" guidance and FP-0012 for the async-dispatch flow that landed alongside.
Run reyn skills <name> for the full description and entry instructions of any skill.
