Skill Claude CodeCodex
Operate any Obsidian vault as a living, self-rewriting second brain (an evolution of Karpathy's LLM Wiki pattern: sources rewrite existing pages, contradictions reconcile automatically, scheduled agents maintain the vault while you sleep). Use this skill whenever the user asks Claude to read, write, update, search, or…

Extract structured knowledge from source material. Comprehensive extraction is the default — every insight that serves the domain gets extracted. For domain-relevant sources, skip rate must be below 10%. Zero extraction from a domain-relevant source is a BUG. Triggers on "/reduce", "/reduce [file]", "extract…

Challenge system assumptions against accumulated evidence. Triages observations and tensions, detects patterns, generates proposals. The scientific method applied to knowledge systems. Triggers on "/rethink", "review observations", "challenge assumptions", "what have I learned".
Skill Claude CodeCodex
Scaffold a complete knowledge system. Detects platform, conducts conversation, derives configuration, generates everything. Validates against 15 kernel primitives. Triggers on "/setup", "/setup --advanced", "set up my knowledge system", "create my vault".

Initialize a PM Brain — a markdown-native second brain for a product operator (PM, product lead, founder, or anyone accountable for one product or initiative) doing judgment-heavy work with scattered inputs. Detects greenfield vs. migration mode, runs a focused interview, copies the deterministic scaffold into the…

OKF knowledge navigation. ALWAYS use this skill the moment a 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…
Skill Claude CodeCodex
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…
Skill Claude CodeCodex
Scan the project and migrate existing documentation into OKF format. Use when the user wants to populate the knowledge base from existing docs, README, schemas, API specs, runbooks, or any structured project knowledge.

Declare and refresh a LOCAL MIRROR — a one-way local copy of a chosen zone of an internal tool (Notion today) replicated into this brain's vault as Markdown, so the LOCAL RAG can search and cite it OFFLINE. A mirror is a 'synchronized source' kept locally: copied once, then refreshed on demand. Use when the user wants…
Skill Claude CodeCodex
Switch the ACTIVE UNIVERSE of this brain, or create a new one (ADR 0034). A universe is a soft retrieval scope (e.g. successive employers, clients, spheres): when you work one universe, searches default to its notes plus your cross-cutting ones. Use when the user wants to switch / change / set the current universe /…

Fan-out/fan-in architecture to pull in the DELTA of external sources (Slack, Google Drive / transcripts, Calendar, mail…) via parallel READ-ONLY sub-agents. Internal technical reference — it's the engine of Phase 2 of the main flow (question → sync sources in background) and of a possible morning briefing. Not a user…
