@eidentic/skills

Skill substrate for Eidentic — parse SKILL.md prompt skill manifests, manage skill banks (approve / list / register), run test-gated executable skills signed with ed25519 keypairs, and evolve skills with LLM-driven feedback loops. The skill system enables agents that improve their own behavior over time.

Install

pnpm add @eidentic/skills

Usage

import { SkillBank, parseSkillMd, evolveSkill } from "@eidentic/skills";
import { AIModel } from "@eidentic/model";

// Parse and register a SKILL.md
const manifest = parseSkillMd(`

When asked to summarize, produce a bullet-point list of key points...
`);

const bank = new SkillBank();
await bank.register(manifest);

// Approve for use in agents (agent-authored skills are quarantined until approved)
bank.approve("summarize");

// Evolve an executable skill using LLM-driven refinement
import type { ExecutableSkillDef } from "@eidentic/skills";
const result = await evolveSkill(executableSkill satisfies ExecutableSkillDef, {
  model: new AIModel(anthropic("claude-sonnet-4-5")),
  maxRounds: 3,
