#### Two-stage hierarchical routing (v1.40, [#2792](https://github.com/open-gsd/gsd-core/issues/2792))
|
||||
|
||||
To keep the eager skill-listing token cost low, v1.40 introduces six namespace **meta-skills** (`gsd-workflow`, `gsd-project`, `gsd-quality`, `gsd-context`, `gsd-manage`, `gsd-ideate` — sourced from `commands/gsd/ns-*.md`, but the invocable `name:` is the bare form shown here) layered above the concrete sub-skills. On runtimes with non-recursive skill loaders (claude global, cline, qwen, hermes, augment, trae, antigravity) the installer now realizes this fully: it emits only the 6 namespace router bundles as top-level skills and nests the ~61 concrete skills under `<router>/skills/<name>/SKILL.md`, so the eager listing is ≈6 entries instead of ≈67. The model selects a namespace router, which instructs it to read the nested concrete skill file via a routing table embedded in the router body. On these runtimes concrete skills are **not** directly invocable by bare name via the Skill tool; they are reachable through the router. Slash commands (`/gsd-*`, via the separate commands surface) are unaffected where the runtime has one. On runtimes with recursive or unconfirmed skill loaders (cursor, codex, copilot, windsurf, codebuddy, opencode, kilo) the layout remains flat — all skills emitted at the top level as before.

Antigravity moved from nested to flat in #1614: `agy` scans only `skills/<name>/SKILL.md`, so nested sub-skills were unreachable.

The router descriptions use pipe-separated keyword tags (≤ 60 chars) per the Tool Attention research showing keyword-dense tags outperform prose for routing at ~40 % the token cost.

Each router's body contains a routing table. When the model receives a request, it reads the router, identifies the relevant sub-skill by name, then opens `skills/<name>/SKILL.md` via a file-path `Read`. The concrete skill is fully available — it is not invocable by bare name through the Skill tool's top-level listing, but is reachable through the router.

### Structural facts
|
||||
|
||||
- **All 15 skill-bearing runtimes use `prefix: "gsd-"`.** Gemini is the only runtime with no skills kind (commands-only TOML).
|
||||
- **Six runtimes nest** (cline, qwen, hermes, augment, trae, antigravity) because their skill loaders scan one level deep — nesting drops nested concrete skills out of the eager top-level listing while keeping them readable by file path (the namespace-router contract, #69).
|
||||
- **Eight runtimes stay flat**: three because their loaders recurse (cursor, opencode, kilo — nesting saves nothing), one because nesting was reverted (claude — the Skill tool errors on unknown names rather than re-routing, #924), and four conservatively where the loader depth is unconfirmed (codex, copilot, windsurf, codebuddy).
|
||||
- **Five runtimes nest** (cline, qwen, hermes, augment, trae) because their skill loaders scan one level deep — nesting drops nested concrete skills out of the eager top-level listing while keeping them readable by file path (the namespace-router contract, #69).
|
||||
- **Nine runtimes stay flat**: three because their loaders recurse (cursor, opencode, kilo — nesting saves nothing), two because nesting was reverted (claude — the Skill tool errors on unknown names rather than re-routing, #924; antigravity — `agy` scans only `skills/<name>/SKILL.md`, so nested sub-skills were unreachable, #1614), and four conservatively where the loader depth is unconfirmed (codex, copilot, windsurf, codebuddy).
|
||||
- **Three runtimes share `convertClaudeCommandToClaudeSkill`** (claude, qwen, hermes). The converter branches on the `runtime` arg for per-runtime branding (Hermes `version:`, Qwen `priority:`).
