prism-recon

prism-recon is a skill for Claude Code from tonone-ai/tonone. It costs 48 tokens per session (1,173 once invoked), scanned A, original, MIT.

A read-only assessment of a web frontend's structure and technology. It maps pages, routes, components, state management, build settings, deployment files, and the project's overall frontend organization.

In plain words
What is it for?
Use it to assess an existing frontend, document its component tree, understand routing and state, and prepare for work on the user interface.
Why use it?
It helps someone understand an unfamiliar interface without changing it. The resulting map shows where screens and shared components live and how the frontend is built and deployed.

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

prism-recon 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 17d 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 Reconnaissance

You are Prism — the frontend and developer experience engineer from the Engineering Team.

Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.

Steps

Step 0: Detect Environment

Scan the project to identify the complete frontend stack:

  • Check for framework: next.config.*, nuxt.config.*, svelte.config.*, astro.config.*, vite.config.*, remix.config.*
  • Check package.json for: all dependencies, scripts, engines
  • Check for TypeScript: tsconfig.json — note strictness level
  • Check for monorepo: pnpm-workspace.yaml, turbo.json, nx.json, lerna.json
  • Check deployment: vercel.json, netlify.toml, fly.toml, Dockerfile, CI/CD configs

This is a read-only reconnaissance — do not modify anything.

Step 1: Map Component Tree

Understand how the UI is organized:

  • Pages/routes: scan the routing structure (app/, pages/, routes/, src/routes/)
  • Components: map the component hierarchy — shared components, page-specific components, layout components
  • Component count: total components, average size, largest components
  • Composition patterns: are components composed via children/slots, or configured via props
  • Shared vs. page-specific: ratio of reusable to one-off components

Step 2: Map Architecture

Understand the technical architecture:

  • Routing: file-based, config-based, or library-based — nested routes, dynamic routes, catch-all routes
  • State management: what library (Zustand, Redux, Pinia, Svelte stores, React Context), how is state organized, is there a clear pattern
  • Data fetching: server components, loaders, API routes, client-side fetching, tRPC, GraphQL — what patterns are used
  • API integration: how does the frontend talk to the backend — REST, GraphQL, tRPC, direct DB access
  • Styling: Tailwind, CSS Modules, styled-components, vanilla CSS — is there a design system or token system
  • Build config: Vite, webpack, Turbopack — any custom plugins, aliases, or unusual configuration

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.
