Distribute a Skill Across All Agents

When to Use

• Use when a skill should be made available across multiple local agent skill folders.
• Use when the user asks to sync or distribute skill updates to other agents.

The user has 4 agent skill locations on his MacBook. A skill must exist in each (or via symlink) to be discoverable by every agent.

The 4 Canonical Locations

Workflow

1. Author the skill in ~/.agents/skills/<skill-name>/SKILL.md (canonical). Follow effective-agent-skills SKILL.md guidance.
2. Verify the .claude symlink is intact (one-time check):

   ls -la ~/.claude/skills
   # Expect: ~/.claude/skills -> ~/.agents/skills
   

   If it's a real directory instead of a symlink, the user has diverged copies — ask before touching.
3. Copy to .hermes only (.claude and .pi are symlinks — already covered):

   SKILL=<skill-name>
   cp -r ~/.agents/skills/$SKILL ~/.hermes/skills/
   

4. Verify all 4 locations show identical byte counts:

   for p in ~/.agents/skills/$SKILL ~/.claude/skills/$SKILL ~/.pi/agent/skills/$SKILL ~/.hermes/skills/$SKILL; do
     echo "$p: $(wc -c < $p/SKILL.md) bytes"
   done
   

   All four numbers must match. If .claude or .pi shows a different byte count, that symlink is broken — investigate before proceeding.

Updating an Existing Distributed Skill

Same flow — re-copy from ~/.agents/skills/ to .hermes/skills/. The .claude and .pi symlinks update automatically. cp -r overwrites by default; use rsync -a --delete if the skill folder has nested files that may have been removed:

rsync -a --delete ~/.agents/skills/$SKILL/ ~/.hermes/skills/$SKILL/

Pitfalls

• ~/.pi/skills/ is the wrong location. Pi Agent loads from ~/.pi/agent/skills/ only. A skill placed in ~/.pi/skills/ is invisible. If you find skills already there, they're orphans — confirm with the user before deleting.
• ~/.claude/skills is a symlink, not a folder. cp -r ~/.agents/skills/foo ~/.claude/skills/ will error with "are identical". Skip the explicit Claude copy.
• Project-local skills exist too — ./.pi/agent/skills/ (or .pi/skills/) inside a repo overrides the global one on collision (later-discovered wins). This skill only handles GLOBAL distribution.
• .pi/agent/skills is a symlink → .agents/skills. Don't cp into it (errors "are identical"); it auto-syncs. Only .hermes/skills is an independent copy — don't unilaterally consolidate Hermes into a symlink unless the user asks.
• Hermes snapshots skills at session start. A newly-distributed skill won't appear inside a running Hermes session until restart (it works fine for future sessions and for the other 3 agents immediately).
• Filename casing matters on case-sensitive volumes. SKILL.md must be uppercase.

When NOT to Use This Skill

• Skill is project-specific → put it in ./.claude/skills/, ./.pi/agent/skills/, etc. inside the repo, not globally.
• Editing one agent's skill only (e.g. a Hermes-only workflow) → patch that file directly, don't propagate.
• Removing a skill globally is destructive. First show the exact skill directories that would be removed, confirm with the user, then use the user's preferred safe deletion method for ~/.agents/skills/ and ~/.hermes/skills/.

Limitations

• Adapted from davidondrej/skills; verify local paths, tools, credentials, and agent features before acting.
• For commands, remote access, scheduling, browser automation, or file-changing workflows, get explicit user approval and confirm the target environment first.
