init-deep

init-deep is a skill for Claude Code, Codex from ArabelaTso/Skills-4-SE. It costs 45 tokens per session (893 once invoked), scanned A, original, Apache-2.0.

A setup tool that creates layered CLAUDE.md context files throughout a project directory. These files give AI coding agents instructions and knowledge specific to the project and each major folder.

In plain words
What is it for?
Use it when onboarding an AI agent, starting a new project, or refreshing project guidance after a major restructure.
Why use it?
It helps an AI understand local architecture, conventions, boundaries, and testing practices without loading the entire codebase at once.

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

init-deep 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 4d 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.

Init Deep — Hierarchical Context Generator

Automatically generates layered context files throughout a project's directory tree, giving AI agents directory-specific knowledge without loading the entire codebase into context.

When to Use This Skill

  • Setting up a new project for AI-assisted development
  • Onboarding AI agents to an existing codebase
  • After major restructuring when context files are outdated
  • When AI agents lack understanding of project-specific conventions

What This Skill Does

Concept

Create an CLAUDE.md file at each significant directory level:

project/
├── CLAUDE.md              # Project-wide: overview, conventions, anti-patterns
├── src/
│   ├── CLAUDE.md          # src-specific: architecture, module boundaries
│   ├── api/
│   │   └── CLAUDE.md      # API-specific: routes, middleware, auth patterns
│   └── components/
│       └── CLAUDE.md      # Component-specific: naming, props, styling
├── tests/
│   └── CLAUDE.md          # Test-specific: frameworks, fixtures, patterns
└── infra/
    └── CLAUDE.md          # Infra-specific: deployment, configs, secrets

When an AI reads src/api/routes/auth.ts, it automatically picks up context from:

  1. project/CLAUDE.md (project-wide)
  2. project/src/CLAUDE.md (source conventions)
  3. project/src/api/CLAUDE.md (API patterns)

Generation Process

  1. Scan the project structure (respect .gitignore)
  2. Analyze each directory:
    • What files are here? What do they do?
    • What patterns/conventions are used?
    • What are the key dependencies?
    • What should an AI know before editing files here?
  3. Generate CLAUDE.md with:
    • OVERVIEW: What this directory contains
    • STRUCTURE: Key files and their purposes
    • WHERE TO LOOK: Task-to-file mapping table
    • CONVENTIONS: Naming, patterns, style rules
    • ANTI-PATTERNS: What NOT to do here
    • COMMANDS: Relevant build/test/run commands

Content Guidelines

Each CLAUDE.md should be:

  • Concise — Under 100 lines. AI context window is precious.
  • Actionable — "WHERE TO LOOK" tables, not prose descriptions
  • Specific — Conventions for THIS directory, not general advice
  • Current — Regenerate after major restructuring

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.

init-deep is a skill published in the GitHub repository ArabelaTso/Skills-4-SE (250 stars, last pushed 18d ago), licensed Apache-2.0. It adds 45 tokens to every session and 893 once invoked, about $0.0002 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 2026-09-03.
