Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00058 | $0.04472 |
| Opus 5 | $0.00029 | $0.02236 |
| Sonnet 5 | $0.00012 | $0.00894 |
| Haiku 4.5 | $0.00006 | $0.00447 |
Grade A, and why
sb-hub scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 245 lines — stays where its author put it; the contents beside it link to each section on GitHub.
sb-hub — onboarding check · orchestrator · navigator
The hub. You don't author here — you inspect state and route. Three read-only modes; pick by
intent. Read CONTEXT.md once for shared vocabulary, the storage map, and the resume protocol.
Load by mode (don't pull both refs up front):
references/runbook.md— the navigator engine (state detection → one next step). Load it for Mode 0 / Mode 2 (diagnose / "what's next").references/end-to-end-flow.md(~220 lines) — the full pipeline worked example for "messy app → design system". Load it only for Mode 1 (orchestrate a full audit). Do NOT load it for a Mode-0 onboarding check or a Mode-2 next-step lookup —runbook.mdis all those need.
Canonical context (one source). The bundle has exactly one CONTEXT.md (shared vocab · STORAGE
MAP · resume). It's never hand-duplicated: in the bundle/plugin install every skill reads this one file
(CONTEXT.md / ${CLAUDE_PLUGIN_ROOT}/CONTEXT.md); a standalone npx skills add <skill> ships a
byte-identical copy the build vendors, refreshed on update. sb-hub is the orchestrator — if skills
are installed separately, route through sb-hub so the pipeline + shared vocabulary stay authoritative.
Resolve the bundle
Scripts live in scripts/. In this repo: ${CLAUDE_PLUGIN_ROOT}/scripts/.
When installed as a plugin, use ${CLAUDE_PLUGIN_ROOT}/scripts/.
CORE=${CLAUDE_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}} # shared scripts: "$CORE/scripts/<name>"
Pick the mode
| User intent | Mode |
|---|---|
| "is this ready", "where do I start", fresh/unknown repo | 0 · Onboarding check |
| "audit this app", "do the whole thing", "build Storybook for this app" | 1 · Orchestrate |
| "what's next", or after any verb appends to the ledger | 2 · Navigate (default) |
| "this is wrong", "strange behavior", "report a bug", a skill misfired | 3 · Report |
Mode 0 — Onboarding check (phase-0 diagnose, read-only)
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

sb-hub is a skill published in the GitHub repository strongeron/storybook-workbench (33 stars, last pushed 2mo ago), licensed MIT. It adds 58 tokens to every session and 4,472 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
