About the project

SkillHub is a self-hosted registry where organizations publish, discover, version, and manage reusable skills for AI agents. Teams use it to share governed skill packages privately, with namespaces, role-based access control, audit logs, and CLI installation; the catalogue entries are skills and related agent integrations that can be managed through it.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

frontend-conventions 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 5d 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.

Frontend Conventions Skill

Trigger

Use this skill when:

  • Adding or modifying React/TypeScript frontend code
  • Creating new pages, features, entities, or shared components
  • Changing API client calls or data fetching patterns

Rules

Feature-Sliced Design

Place code at the lowest appropriate layer:

Layer Path Purpose
Pages web/src/pages/ Route-level page components
Features web/src/features/ Business features (search, upload, review, etc.)
Entities web/src/entities/ Domain entity display logic (skill, user, namespace)
Shared web/src/shared/ Reusable UI components, hooks, utilities

Current features:

  • admin — Admin panel (user management, labels, search)
  • auth — Login, OAuth flows, device auth
  • governance — Skill governance actions (hide, yank, archive)
  • namespace — Namespace management (members, settings)
  • notification — User notifications and inbox
  • promotion — Skill promotion between scopes
  • publish — Skill upload/publish UI
  • report — Skill reporting
  • review — Review workflow UI
  • search — Skill search and filtering
  • security-audit — Security audit viewer
  • skill — Skill detail, listing, cards
  • social — Stars, ratings, subscriptions
  • token — API token management

Data Fetching

  • Always use TanStack Query (@tanstack/react-query) for server state.
  • Never use useEffect for data fetching.
  • Use openapi-fetch client with generated types from web/src/api/generated/schema.d.ts.
  • Never use any types.

State Management

  • TanStack Query for server state (API data, caching, invalidation, optimistic updates)
  • Zustand for local/UI state (theme, sidebar, modals, form state)

Component Composition

  • Radix UI primitives: @radix-ui/react-dropdown-menu, @radix-ui/react-select
  • class-variance-authority (cva) for component variants
  • clsx + tailwind-merge for class merging
  • cn() utility: web/src/shared/lib/utils.ts
  • shadcn/ui is NOT used as a library

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.
