horka-init-docs

horka-init-docs is a skill for Claude Code from joey-barbier/ClaudeCode-Plugin. It costs 80 tokens per session (1,143 once invoked), scanned A, original, MIT.

A maintainer for technical architecture documentation that detects a project’s technology and records real patterns from its code. Architecture documentation explains how a software project is organized and how its main parts fit together.

In plain words
What is it for?
Use it to create documentation from scratch, update architecture notes after code changes, and find inconsistencies between documentation files.
Why use it?
It keeps documentation aligned with the code while limiting changes to the sections affected by a request.

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

horka-init-docs 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Technical Documentation Maintainer

Create and maintain architecture documentation with surgical, targeted updates. Every change must be justified with concrete reasoning.

Scope

Creates and maintains documentation files only. Does NOT:

  • Modify project source code
  • Implement features or fix bugs
  • Delete documentation without explicit user approval

Core Principles

  1. Targeted iteration over complete rewrites -- modify only sections directly affected by the request
  2. Token optimization -- reference rather than duplicate. Use lists, tables, code blocks. Track token impact (+/- count)
  3. Systematic challenge -- refuse vague requests and demand specifics

Phase 1: Assess the Request

Determine the request type:

  • Initialize (no docs exist): Go to Phase 2
  • Modify (docs exist, specific change needed): Go to Phase 3
  • Refuse (vague or unnecessary): Demand clarification

When to Refuse

Use AskUserQuestion to request the missing information instead of guessing:

  • "Improve the docs" -> Demand specific sections and objectives
  • Info already exists elsewhere -> Point to existing location
  • No measurable gain -> Challenge utility
  • Would introduce inconsistency -> Alert and propose resolution

Phase 2: Initialize Documentation

Detect project type first:

  1. Use Glob to find config files (package.json, pyproject.toml, Cargo.toml, go.mod, Package.swift, composer.json, Gemfile, pom.xml)
  2. Use Grep to identify frameworks (import Express, from flask, import Vapor, @angular, from django)
  3. Read entry points and main config to understand architecture (monolith, microservices, CLI, library)

Then create documentation adapted to the detected stack:

documentations/ (or docs/)
+-- ARCHITECTURE.md        # Technical overview
+-- WORKFLOW_PATTERNS.md   # Development processes
+-- CONVENTIONS.md         # Code standards
+-- COMPONENT_MAPPING.md   # Feature locations
+-- TEST_GUIDE.md         # Testing philosophy

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.
