# NousResearch/hermes-agent · Namespaced skill registration to avoid name collisions

## Open now

- Nothing open on GitHub.

These members concern adding support for namespaced skill names (e.g. 'superpowers:writing-plans') when registering skills via plugins, allowing bundled skills to avoid naming collisions.

## TL;DR

- 3 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 1 PR(s) closed without merging.
- A fix was merged to main in PR #9786. Verify it addresses your case.
- **Recommended:** read PR #9786 (and any competing PRs below) before filing. Confirm the merged change covers your symptom.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `resolved` · deciding PR(s): `pr-9786`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.67`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.

## Closed / duplicate issues

- #8422: \[Feature\]: Support namespaced skill names (e.g. superpowers:writing-plans) to avoid name collisions

## Prior & competing PRs

    +The agent can now load your skills with their namespaced name:
     
    -def register(ctx):
    -    ctx.register_tool(...)
    -    _install_skill()
    +```python
    +skill_view("my-plugin:my-workflow")   # → plugin's version
    +skill_view("my-workflow")              # → built-in version (unchanged)

    +**Key properties:**
    +- Plugin skills are **read-only** — they don't enter `~/.hermes/skills/` and can't be edited via `skill_manage`.
    +- Plugin skills are **not** listed in the system prompt's `<available_skills>` index — they're opt-in explicit loads.
    +- Bare skill names are unaffected — the namespace prevents collisions with built-in skills.
    +- When the agent loads a plugin skill, a bundle context banner is prepended listing sibling skills from the same plugin.
    +
    +:::tip Legacy pattern
    +The old `shutil.copy2` pattern (copying a skill into `~/.hermes/skills/`) still works but creates name collision risk with built-in skills. Prefer `ctx.register_skill()` for new plugins.

    +## Plugin-Provided Skills
    +
    +Plugins can bundle their own skills using namespaced names (`plugin:skill`). This prevents name collisions with built-in skills.
    +
    +```bash
    +# Load a plugin skill by its qualified name
    +skill_view("superpowers:writing-plans")
    +
    +# Built-in skill with the same base name is unaffected
    +skill_view("writing-plans")
    +```
    +
    +Plugin skills are **not** listed in the system prompt and don't appear in `skills_list`. They're opt-in — load them explicitly when you know a plugin provides one. When loaded, the agent sees a banner listing sibling skills from the same plugin.
    +
    +For how to ship skills in your own plugin, see [Build a Hermes Plugin → Bundle skills](/docs/guides/build-a-hermes-plugin#bundle-skills).
