wacon-knowledge

wacon-knowledge is a skill for Claude Code, Codex from JOSETRA44/wacon-mcp. It costs 154 tokens per session (1,601 once invoked), scanned A, original, MIT.

A set of instructions for turning WhatsApp chat history into a structured knowledge base called Wacon. It extracts contact facts, summarizes conversation episodes, reviews suggestions, and maintains a profile of the user’s communication style.

In plain words
What is it for?
Use it to analyze WhatsApp conversations, build contact profiles, consolidate chat episodes, review actionable suggestions, and keep the user persona current. It supports bulk analysis modes and JSON output for command-line data.
Why use it?
It avoids making the agent read every raw message one by one by using bulk analysis first. It also provides commands for checking WhatsApp connectivity, available chats, extracted facts, and system health.

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

wacon-knowledge 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 9d 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.

Wacon — construir la base de conocimiento

Tu trabajo aquí no es conversar: es convertir el historial de WhatsApp en memoria estructurada (perfiles de estilo, hechos por contacto, episodios resumidos, sugerencias accionables, persona del usuario).

La idea central: Wacon ya hace el trabajo duro sin gastar tokens. Tú no lees chats crudos uno por uno — disparas el análisis masivo determinístico y luego enriqueces lo que quedó pre-masticado. Leer historial completo es el último recurso, no el primero.

Si prefieres la CLI

Todos los comandos de datos aceptan --json, que imprime el objeto tal cual sin códigos de color (esos ensucian tu contexto). Úsalo siempre: wacon targets --json, wacon facts <chat> --json, wacon doctor --json. Nunca lances wacon chat: es interactivo, para humanos, y te bloquearía.

El flujo

1. Comprueba que hay con qué trabajar

whatsapp_status (¿conectado? ¿cuántos mensajes?) y wacon_doctor si algo falla. Sin historial sincronizado no hay nada que analizar.

2. Dispara la fuerza bruta (gratis)

run_bulk_analysis({ mode }) — corre en el daemon y responde al instante:

mode Cuándo
contacts Por defecto: personas (chats 1-a-1)
courses Solo grupos de cursos/universidad
groups Todos los grupos
all Todo
chat Un chat concreto (scope.chat)

Luego analysis_status para seguir el progreso (procesados/total, hechos, episodios, sugerencias). Esto construye perfiles de estilo, segmenta episodios con resúmenes extractivos, extrae hechos candidatos y recoge accionables — todo sin IA.

3. Decide dónde profundizar

list_analysis_targets te da la lista priorizada: quién tiene más conversación y quién todavía no tiene hechos. Empieza por ahí.

Filtra con criterio: los grupos de ventas, juegos o apuestas casi nunca aportan conocimiento útil sobre las personas. Los de cursos, trabajo y familia sí.

4. Enriquece con get_analysis_bundle(chat)

Te devuelve todo lo que ya se extrajo: estilo, dinámica, hechos confirmados, hechos candidatos, episodios (muchos con resumen [auto]) y accionables. Sobre eso:

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.
