What is shadcn-brief CLAUDE.md?

A set of project instructions for Claude Code, the coding agent, in a repository that uses a file named CLAUDE.md.

Use it when working in the referenced repository so Claude Code can find its baseline instructions, module-specific guidance, and verification rules.

It tells the agent which project rules and entry-point documents to follow while implementing and checking changes.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01614	$0.01614
Opus 5	$0.00807	$0.00807
Sonnet 5	$0.00323	$0.00323
Haiku 4.5	$0.00161	$0.00161

Security

Grade A, and why

shadcn-brief CLAUDE.md 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.

CLAUDE.md

This file defines Claude Code specific execution guidance for this repository. Repository-wide rules and facts live in AGENTS.md; this file only adds Claude-focused operating rules.

1. Role And Boundaries

Role: implementer plus verifier.
Principles: minimal changes, evidence-backed delivery, easy rollback.
Boundaries: do not perform high-risk actions without approval, do not bypass gates, and do not create docs drift.

1.1 Module Entry Points

Root baseline: AGENTS.md, CLAUDE.md
services/mcp-server/src/: services/mcp-server/src/next-smoke/CLAUDE.md, services/mcp-server/src/providers/CLAUDE.md, services/mcp-server/src/retrieval/CLAUDE.md, services/mcp-server/src/tools/CLAUDE.md, services/mcp-server/src/uiux/CLAUDE.md
packages/: packages/contracts/CLAUDE.md, packages/shared-runtime/CLAUDE.md, packages/runtime-observability/CLAUDE.md
tests/: tests/e2e/CLAUDE.md, tests/visual-golden/CLAUDE.md
tooling/: tooling/contracts/CLAUDE.md, tooling/env-contract/CLAUDE.md, tooling/shared/CLAUDE.md
services/: services/gemini-sidecar/CLAUDE.md
ops/: ops/CLAUDE.md

Rule priority remains:

system/platform instructions
root AGENTS.md
module AGENTS.md
module CLAUDE.md

1.2 Repository Facts Snapshot

Primary product shape: local stdio MCP server plus a default product frontend at apps/web
Frontend stack target: Next.js App Router + React + Tailwind + shadcn
Model strategy: Gemini-only
Minimum merge gate: npm run lint && npm run typecheck && npm run test
Mainline acceptance gate: npm run ci:gate

2. Start-Of-Task Checklist

Read AGENTS.md, README.md, and docs/index.md.
Identify the impacted modules and nearby tests before editing.
Pick the smallest valid verification set for the task.
If the task touches E2E or CI paths, ensure Playwright browsers are installed:

npx playwright install chromium firefox webkit

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.
