Skills Manager

Unified skill lifecycle management across agents.

Usage

/skills-manager                    # Quick status overview
/skills-manager list               # All skills with origin, description, agent
/skills-manager search <query>     # Search skills.sh ecosystem
/skills-manager install <source>   # Install from ecosystem or GitHub
/skills-manager remove <name>      # Remove a skill
/skills-manager inspect <name>     # Deep-read: frontmatter, scripts, structure
/skills-manager validate [path]    # Validate structure and frontmatter
/skills-manager audit              # System-wide health check
/skills-manager update             # Check and apply ecosystem updates
/skills-manager create             # Guided creation (delegates to skill-creator)

Status (/skills-manager)

Quick overview of all installed skills.

bun ~/.claude/skills/skills-manager/scripts/manage.ts status

Shows: total count, breakdown by origin (local/ecosystem/symlink) and agent, lock file stats, validation issue count.

---

List (/skills-manager list)

All installed skills across agents with metadata.

Local skills:

bun ~/.claude/skills/skills-manager/scripts/manage.ts list

Ecosystem skills (via npx):

npx skills list -g

Present both outputs together — local list shows origin/agent/description, ecosystem list shows remote registry state.

---

Search (/skills-manager search )

Search the skills.sh ecosystem for installable skills.

npx skills find <query>

Present results with name, source, and install command. If no results, suggest npx skills find (interactive mode) or creating a custom skill.

---

Install (/skills-manager install )

Install a skill from the ecosystem or GitHub.

npx skills add <source> -g -y

Source formats:

• owner/repo@skill-name — from skills.sh registry
• https://github.com/owner/repo — from GitHub directly
• Local path — for development

The -g flag installs globally (user-level), -y skips confirmation.

After install, run validate to confirm the skill is well-formed:

bun ~/.claude/skills/skills-manager/scripts/manage.ts validate ~/.agents/skills/<name>

---

Remove (/skills-manager remove )

Remove an installed skill.

npx skills remove <name> -g -y

---

Inspect (/skills-manager inspect )

Deep-read a specific skill by name.

bun ~/.claude/skills/skills-manager/scripts/manage.ts inspect <name>

Shows: path, origin, agent, symlink target, frontmatter fields, scripts with size and executable status, references directory listing, SKILL.md heading structure.

---

Validate (/skills-manager validate [path])

Validate skill structure and frontmatter against the spec.

bun ~/.claude/skills/skills-manager/scripts/manage.ts validate <path>

Path can be:

• A single skill directory (containing SKILL.md)
• A directory of skills (e.g., ~/.claude/skills)

Checks performed

Errors (blocking):

• SKILL.md exists with valid frontmatter
• Required fields: name, description
• Name: hyphen-case, max 64 chars, no leading/trailing/consecutive hyphens
• Description: 50+ chars, max 1024 chars, no angle brackets
• No forbidden files (README.md, CHANGELOG.md, etc.)

Warnings:

• Non-spec frontmatter keys (origin, inspired-by, hooks, status) — suggest metadata: migration
• Unexpected keys beyond spec-allowed set
• SKILL.md over 500 lines
• Scripts not executable
• Broken internal file references

---

Audit (/skills-manager audit)

System-wide health check across all agents.

bun ~/.claude/skills/skills-manager/scripts/manage.ts audit

Runs:

1. Validation — every skill checked against spec
2. Symlink health — dead symlinks flagged
3. Lock file consistency — lock entries with missing directories
4. Name overlap — same skill name across agents

Returns exit code 1 if any errors found.

---

Update (/skills-manager update)

Check for and apply ecosystem skill updates.

Check for updates:

npx skills check

Apply updates:

npx skills update

---

Create (/skills-manager create)

Delegates to the skill-creator skill for guided 6-step creation.

When user runs /skills-manager create:

1. Invoke /skill-creator which provides the full guided workflow
2. After creation, run validate on the new skill:

   bun ~/.claude/skills/skills-manager/scripts/manage.ts validate <new-skill-path>
   

---

Cross-Agent Reference

Agent	Skills Dir	Lock File
Claude Code	~/.claude/skills/	~/.agents/.skill-lock.json
Codex	~/.codex/skills/	~/.agents/.skill-lock.json
Agents CLI	~/.agents/skills/	~/.agents/.skill-lock.json

All agents share the same lock file. The npx skills CLI auto-detects which agents are installed and manages skills for all of them.

Skill Conventions

• Frontmatter: name (hyphen-case), description (50-1024 chars), license (Apache-2.0)
• Structure: SKILL.md + optional scripts/, references/, assets/
• Forbidden: README.md, CHANGELOG.md, INSTALLATION.md, QUICK_REFERENCE.md
• Non-spec keys: origin, inspired-by, status, hooks — should migrate to metadata:
• Experimental skills: status: experimental in frontmatter (no directory prefix)
