Provider Support

Echo Wiki uses the Agent Skills open standard, with one canonical set of definitions in .claude/skills/. Skill discovery paths depend on the agent.

Supported Agents

Agent	Instruction File	Skill loading
Claude Code	CLAUDE.md	Native discovery in .claude/skills/; invoke /name
Codex	AGENTS.md	Native discovery through .agents/skills/ links; select a skill or use $name where supported
Gemini CLI	GEMINI.md	Instructions point to .claude/skills/; explicitly load the file if needed
Other Agent Skills agents	Agent-specific	Verify that agent's discovery path or explicitly load SKILL.md

How It Works

Each agent reads its instruction file (CLAUDE.md, AGENTS.md, or GEMINI.md) which points to:

• _meta/wiki.config.yaml for domain configuration
• .claude/skills/ for operation definitions (onboard, ingest, compile, rebuild, index, lint, query, context, maintain)
• _meta/schemas/frontmatter.yaml for validation rules

Instruction loading and native skill discovery are separate. Echo Wiki includes .agents/skills/<name> relative links pointing to ../../.claude/skills/<name>, so Codex and Claude share each skill and its supporting files. Onboarding creates the links automatically; existing instances can add missing links without reinstalling. Keep these as Git symlinks rather than duplicate directories.

The skills themselves are markdown files with YAML frontmatter — human-readable and agent-executable.

Agent Skills Specification

Skills follow the Agent Skills open standard:

.claude/skills/
├── onboard/
│   ├── SKILL.md
│   ├── scripts/
│   └── references/
├── ingest/
│   └── SKILL.md    # name: ingest
├── compile/
│   └── SKILL.md    # name: compile
├── rebuild/
│   └── SKILL.md    # name: rebuild
├── index/
│   └── SKILL.md    # name: index
├── lint/
│   └── SKILL.md    # name: lint
├── query/
│   └── SKILL.md    # name: query
├── context/
│   └── SKILL.md    # name: context
└── maintain/
    └── SKILL.md    # name: maintain

Each SKILL.md contains:

• YAML frontmatter with name and description
• Step-by-step markdown instructions the agent follows
• References to schemas and config files

First-time Onboarding

An agent does not need automatic skill discovery to bootstrap a repository. Give it the absolute path to a complete Echo Wiki checkout's .claude/skills/onboard/SKILL.md and the destination repository. See Getting Started for fresh and existing-repository examples. Verify each agent's instruction loading and command support; the skill does not install or authenticate an agent.
