vh 53c3e8000e docs: add FleetTools — an agent-family-agnostic index of fleet capability
Every agent on nh3-dev — Claude, Codex, Grok, Aider — needs the same
answers: what runs here, how do I call it, what will bite me. Until now
that lived in ~/.claude/CLAUDE.md, which only Claude sessions load, and
it was interleaved with operator preferences that other families have
no use for.

Two-tier by design, matching the persistent-memory split: FLEETTOOLS.md
is a 135-line index an agent reads whole, and each entry links to a
detail file it opens only when it actually needs that tool. Reading the
index costs about a fifth of reading the tree.

Detail paths are absolute so they resolve from any working directory,
since a non-Claude agent will cat the path rather than follow a
markdown link. ~/FLEETTOOLS.md symlinks to the index for discovery.

Rule zero is that live inventories get queried, not transcribed:
Homepage /api/services, asset-engine /api/v1/services, LiteLLM
/v1/models, and every FastAPI seat's /openapi.json. A copied service
table would be stale within a month and this repo already has a
standing rule against second copies that drift.

Contents verified against the running fleet rather than copied from
existing docs: binaries resolved on PATH, seven endpoints probed live,
the LiteLLM roster counted at 40 models where the old note said ~30.
No credentials are included; the vault and its CLI are pointed at
instead.

Arbo — catalog-driven image generation engine

Endpoint: http://irv-ml1.nh3.internal:8201 (title ImageGen Engine, v1.16.2) Bare ComfyUI underneath: http://irv-ml1.nh3.internal:8188 Repo: gitea vh/arbo · deploy is deploy-engine.sh + a gitea Actions webhook on push.

Runs on CPU on irv-ml1 and dispatches to ComfyUI. GET /openapi.json is the live contract — the paths below are the map, not the spec.

Jobs

POST /workflows/{workflow_id}/run     -> 202, a job id
GET  /jobs                            GET  /jobs/{job_id}
POST /jobs/{job_id}/cancel
GET  /artifacts/{job_id}/{index}      # the rendered output

Character Studio — dataset → LoRA pipeline

POST,GET /character-studio

Traps

  • A new Python dependency needs docker exec arbo pip install --user <pkg> — the deploy script does not rebuild the image.
  • Triton backend is a HARD NO on the Ampere ComfyUI seat. It crashes every render on the A6000 (fp8e4nv unsupported on sm_86); a cu130 bump does not fix it. Deferred until an Ada/Blackwell card is in that slot.
  • The mmartial ComfyUI image crash-loops if anything runs pip as root inside it — that breaks the venv. Fix: chown -R 1000:1000 venv. Set DISABLE_UPGRADES=true to pin torch.
  • Render results belong in a booth (docs/fleettools/booth.md), not described in prose.
