What it does
Claude Mega Brain is an agent skill from guhcostan/claude-mega-brain. OKF knowledge navigation. ALWAYS use this skill the moment a <mega-brain block appears in session context — it means the project has documented concepts and you must consult them before answering questions about data, schemas, metrics, APIs, or systems. Also trigger when the user asks about a table, column, metric definition, service, or API endpoint and there's any chance it's documented in the project. When in doubt, read the file directly.
Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Knowledge Management, covering REST APIs and Product metrics. The repository describes itself as: OKF-powered knowledge context for Claude Code — injects your project's knowledge base at every session. The licence is MIT.
When your agent uses it
- The user asks about a table
- Metric definition
- API endpoint and theres any chance its documented in the project
Example prompts
- “s any chance it”
- “/claude-mega-brain”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Read the file — paths in are relative to the project root; use the Read tool directly
- Follow links — text links in the body point to related concepts; read them
- log.md — chronological changelog; last 3 entries are injected automatically
- Linked concepts auto-surface — after you read an OKF file, linked concept summaries appear via PostToolUse hook
What it can do on your machine
Read from SKILL.md and the folder at commit de1ab9c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Claude Mega Brain loads about 588 tokens when it runs. Until then it costs about 117 tokens; SKILL.md has 230 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- OKF knowledge navigation. ALWAYS use this skill the moment a `<mega-brain>` block appears in session context — it means the project has documented concepts and you must consult them before answering questions about data, schemas, metrics, APIs, or systems. Also trigger when the user asks about a table, column, metric definition, service, or API endpoint and there's any chance it's documented in the project. When in doubt, read the file directly.
claude-mega-brain — OKF Knowledge Navigator
When <mega-brain> context is present, the project has OKF-documented concepts — any Markdown file with type: in its YAML frontmatter. These are the authoritative source for domain knowledge: exact schemas, metric formulas, API contracts, runbooks, business definitions. Answers from the knowledge base beat answers from training data.
What OKF files look like
Any .md file anywhere in the project with YAML frontmatter containing type::
---
type: BigQuery Table
title: Orders
description: One row per completed customer order.
resource: https://...
tags: [sales, revenue]
timestamp: 2026-06-29T00:00:00Z

# Schema
| Column | Type | Description |
...No dedicated folder required. The file can live in docs/, wiki/, project root, anywhere.
Navigation
- Read the file — paths in
<mega-brain>are relative to the project root; use the Read tool directly - Follow links —
[text](rel-path.md)links in the body point to related concepts; read them - log.md — chronological changelog; last 3 entries are injected automatically
- Linked concepts auto-surface — after you read an OKF file, linked concept summaries appear via PostToolUse hook
When to proactively read files
- User asks about a data source, table, column, or metric — check
<mega-brain>index first - Before writing SQL, queries, or code that touches project data
- When a business term is ambiguous — OKF has the canonical definition
- When the user says "check the knowledge base", "what do we know about X", or "olha no okf"
If <mega-brain> context is missing
No OKF concepts found in the project yet. Suggest:
/mega-brain:init— createsindex.mdandlog.mdto get started/mega-brain:migrate— scans existing docs and generates OKF files automatically
