What is it for?
Use it to inspect the project structure, read key documentation, identify important backend and frontend files, and record the findings.
Why use it?
It gives an agent shared context about the project before planning or making changes.

Command for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; mentions CLAUDE.md.

This is plipowczan/claude-piv-skeleton's own configuration. It tells Claude Code how to work on claude-piv-skeleton itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude-piv-skeleton configures →

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

prime 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 9d 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.

Prime: Load Project Context

Objective

Build comprehensive understanding of the codebase by analyzing structure, documentation, and key files, then save context to a reusable file for planning phase.

Process

1. Analyze Project Structure

List all tracked files:

git ls-files

Show directory structure:

find . -type f -name "*.java" -o -name "*.ts" -o -name "*.tsx" -o -name "*.md" | grep -v node_modules | grep -v target | head -100

2. Read Core Documentation

Must Read:

  • .claude/CLAUDE.md - Project overview and tech stack
  • README.md - Quick start guide
  • docs/ARCHITECTURE.md - System architecture
  • .claude/rules/ - Modular coding rules

3. Identify Key Files

Based on the structure, identify and read:

Backend (Java 24 + Spring Boot):

  • backend/pom.xml - Maven dependencies and Java version
  • backend/src/main/java/com/example/Application.java - Entry point
  • backend/src/main/resources/application.properties - Configuration
  • Key controllers: backend/src/main/java/com/example/controller/
  • Key services: backend/src/main/java/com/example/service/
  • Key entities: backend/src/main/java/com/example/entity/

Frontend (React 19 + Vite):

  • frontend/package.json - Dependencies
  • frontend/src/main.tsx - Entry point
  • frontend/src/App.tsx - Main app component
  • Key components: frontend/src/components/
  • Key pages: frontend/src/pages/

4. Understand Current State

Check recent activity:

git log -10 --oneline

Check current branch and status:

git status
git branch --show-current

5. Pattern Recognition

Identify key patterns:

Backend Patterns:

  • Repository pattern: Spring Data JDBC (NOT JPA)
  • Service layer: @Service with @RequiredArgsConstructor
  • DTOs: Separate DTO classes for API responses
  • Logging: SLF4J structured logging
  • Error handling: Graceful degradation, continue processing

Frontend Patterns:

  • Functional components with hooks
  • Context API for global state
  • Axios for HTTP client
  • TailwindCSS utility classes
  • TypeScript interfaces

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.
