build-your-users-mind

build-your-users-mind is a skill for Claude Code, Codex from ellmos-ai/build-your-users-mind. It costs 115 tokens per session (1,694 once invoked), scanned A, original, MIT.

A recipe for building a model of a user's preferences from an AI agent's conversation logs. It organizes decisions and outcomes into files that can inform memory, rules, or system prompts.

In plain words
What is it for?
Use it to extract user decision patterns, maintain a preference avatar, predict likely feedback, and compare those predictions with later feedback.
Why use it?
It gives agents a structured way to learn from how a user reacts instead of relying on scattered conversation history. Its predictions remain hypotheses and do not grant permission to act.

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

build-your-users-mind 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.

build-your-users-mind — Agnostisches ToM-Modul (Feedback-Präkognition)

What you mind is what you get. Ein Rezept, kein Framework. Jedes Agenten-Modell baut daraus ein ToM-Modell seines Users: eigene Daten auswerten → Entscheidungsmuster destillieren → Avatar-Dateien pflegen → an die eigene Memory/Regeldatei/System-Prompt anbinden.

Kern = Feedback-Präkognition (feedforward): Sage das User-Feedback voraus, BEVOR es kommt; nutze es als Steuersignal in dessen Abwesenheit; evaluiere die Vorhersage hinterher gegen die Realität.

Vorlagen: templates/ (Avatar-Dateien), scripts/ (Pipeline), TAXONOMY.md (8 Typen), skills/swarm-operations/ (Klassifikations-Schwarm). Eine private Referenz-Implementierung (auf den Logs des Autors) existiert, wird aber nicht mitgeliefert.

Theoretische Basis: Prompt-Archaeology (Methode, Taxonomie in TAXONOMY.md)

  • ToM-Forschung (ToM-SWE arXiv 2510.21903; Persistent Memory & User Profiles 2510.07925).

Grundprinzip

LLMs sehen nie die Roh-Gigabytes. Deterministische Skripte reduzieren zuerst auf ein sauberes Korpus der getippten User-Sätze; erst dann arbeitet ein Klassifikations-Schwarm semantisch. Kern ist nicht „welche Prompts", sondern „welche Entscheidung → welches Ergebnis → war der User zufrieden".

Die 6 Schritte

1. Quelle erschließen (Source-Adapter)

Finde die eigenen Interaktionslogs. Pro Modell unterschiedlich → siehe SOURCE-ADAPTERS.md. Extrahiere nur echte, vom Menschen getippte Prompts (keine Tool-Results, System-Reminder, Hook-Injektionen, Kontext-Kompaktierungs-Summaries). Felder: ts, project, session, text.

2. Reduzieren (deterministisch, kein LLM)

  • Synthetische Turns filtern, Dedup, Boilerplate/Micro-Acks aggregieren.
  • Followup-Verknüpfung: je Prompt den/die nächsten User-Turn(s) als outcome_signal (praise | reissue | correction | abandon | none) ableiten → das Zufriedenheits-Signal.
  • decision_score über ein Entscheidungs-Lexikon (Korrektur/Präferenz/Regel/Steuerung).
  • REDACTION (Pflicht, bevor irgendetwas persistiert): Secrets/Tokens/Keys/Mails — und je nach User auch Gesundheit/Steuer/IP-Adressen. Sensibles des Users wird maskiert.

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.
