deepinit

deepinit is a skill for Claude Code from Yeachan-Heo/oh-my-claudecode. It costs 13 tokens per session (2,217 once invoked), scanned A, original, MIT.

A codebase documentation setup that creates AGENTS.md files throughout a project. These files tell coding agents what each directory contains, how parts relate, and which local instructions apply.

In plain words
What is it for?
Documenting a new or unfamiliar repository, recording directory responsibilities, listing important files, and providing local development instructions.
Why use it?
It removes the need for an agent to infer the project structure and rules from scratch. The linked files let guidance become more specific as the agent moves into deeper directories.

Skill for Claude Code

Written for Claude Code: PostToolUse hook event. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions AGENTS.md.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is **Parent context:** `../AGENTS.md`.

Part of the oh-my-claudecode plugin — 48 skills, 21 commands, 19 agents, 11 hooks, 1 MCP server shipped together

About the project

Oh My Claude Code is a multi-agent orchestration system for Claude Code, coordinating specialized agents, commands, skills, hooks, and workflows. It is designed for developers who want Claude Code to handle coding tasks through coordinated agent roles. Catalogue entries are components of its Claude Code workflow, including agents, commands, skills, hooks, instructions, MCP configuration, and a plugin.

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

deepinit 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 1mo 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.

The opening of the file, as written. The whole thing — 345 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Deep Init Skill

Creates comprehensive, hierarchical AGENTS.md documentation across the entire codebase.

Core Concept

AGENTS.md files serve as AI-readable documentation that helps agents understand:

  • What each directory contains
  • How components relate to each other
  • Special instructions for working in that area
  • Dependencies and relationships

Hierarchical Tagging System

Every AGENTS.md (except root) includes a parent reference line:

**Parent context:** `../AGENTS.md`

This MUST be visible prose, never an HTML comment. Claude Code strips HTML comments before a memory file reaches the model, so <!-- Parent: ... -->, <!-- Generated: ... --> and a commented MANUAL boundary are invisible to the agent that is supposed to act on them.

This creates a navigable hierarchy:

/AGENTS.md                          ← Root (no parent line)
├── src/AGENTS.md                   ← **Parent context:** `../AGENTS.md`
│   ├── src/components/AGENTS.md    ← **Parent context:** `../AGENTS.md`
│   └── src/utils/AGENTS.md         ← **Parent context:** `../AGENTS.md`
└── docs/AGENTS.md                  ← **Parent context:** `../AGENTS.md`

Loading Model

Stock Claude Code discovers nested CLAUDE.md by basename and never loads a nested AGENTS.md; a root @AGENTS.md import does not reach subdirectories either. The nested files generated here are delivered by OMC's PostToolUse directory-context injector, which walks up from each accessed file and injects the nearest AGENTS.md/README.md once per session.

That means the hierarchy requires OMC's hooks to be active. When OMC hooks are disabled (DISABLE_OMC=1, OMC_SKIP_HOOKS=post-tool-use) or the plugin is not registered, add a root-level CLAUDE.md symlink or @AGENTS.md import for the root file and expect nested files to stay unread.

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.
