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.

Initialize OKF knowledge base files in the current project. Use when the user wants to start documenting their project for claude-mega-brain, or when the user says "init mega brain", "setup the knowledge base", "cria o okf", "inicializa o mega brain", "quero usar o mega brain", "criar a estrutura do knowledge base", or asks how to get started with the plugin.

Create or update a single OKF concept file from raw input. Use when the user wants to document a specific table, metric, API, service, or concept in the knowledge base — even if they say "add this to the okf", "documenta essa tabela", "cria um conceito pra isso", "adiciona no knowledge base", "register this API", or pastes a schema/description and says to save it. Always check that okf/ exists first; if not, suggest /mega-brain:init.

Scan the project and migrate existing documentation into OKF format. Use when the user wants to populate the okf/ directory from existing docs, README, schemas, API specs, runbooks, or any structured project knowledge. Trigger on "migrate to okf", "populate the knowledge base", "scan my docs", "convert docs to okf", "importar documentação", "migrar para okf", "popular o knowledge base", "lê meus docs e cria o okf", "generate okf from existing docs", or when the user points at a docs folder and asks to "put it in the knowledge base". Always check that okf/ exists first; if not, run /mega-brain:init before migrating.

Load this skill when analyzing Brazilian stocks listed on B3, building investment portfolios with Brazilian equities, or interpreting data from yfinance, BCB API, and Google News PT-BR. Provides the quality methodology, technical indicator reference, and sector impact framework used in /analyze and /portfolio.

ALWAYS read this skill before writing any Workflow tool script, before calling the Workflow() tool, or before spawning more than 3 agents. Covers the critical patterns that prevent wasted tokens and wrong model choices: pipeline() vs parallel(), Haiku for fan-out agents, never use agents just to write files (return results instead), schema output, phase organization, and resume. Triggers on: writing a workflow script, Workflow({ script: ... }), pipeline(), parallel(), agent() in a loop, "run in parallel", "fan-out", "orchestrate subagents", "multi-agent", "haiku for agents", "how do I save results from a workflow", "workflow burning tokens", "too many agents", "model for subagents". If you are about to write a workflow script or call Workflow() — stop and read this first.

Use when conducting research on any real-world topic — products, services, finance, health, travel, or life decisions. Ensures sources are fetched, cross-referenced, and not fabricated.
