Du Dum

Category: Engineering · Sub-category: architecture · Last updated: 2026-05-21

Separate expensive observation from cheap decision-making in autonomous agent loops using a two-clock architecture. A fast clock accumulates data into a digest file; a slow clock reads the digest and acts only when something is pending. Idle cycles cost nothing because the action clock returns immediately after reading an empty digest. Use when building autonomous agents that must observe continuously but can only afford to act occasionally, when API or LLM costs dominate and most cycles have nothing to do, when designing cron-based agent architectures with observation and action phases, or when an existing heartbeat loop is too expensive because it calls the LLM on every tick.

From the source SKILL.md

Beobachtung von Aktion mit zwei Uhren trennen die mit unterschiedlichen Frequenzen laufen. Die schnelle Uhr (Analyse) sammelt Daten guenstig und schreibt einen kompakten Digest. Die langsame Uhr (Aktion) liest den Digest und entscheidet ob zu handeln ist. Wenn der Digest sagt dass nichts ansteht, beendet die Aktions-Uhr sofort -- null Kosten fuer Idle-Zyklen.

What this skill does

Du Dum is a community-contributed Claude Code skill in the architecture sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/du-dum/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when building autonomous agents that must observe continuously but can only afford to act occasionally, when API or LLM costs dominate and most cycles have nothing to do, when designing cron-based agent architectures with observation and action phases, or when an existing heartbeat loop is too expensive because it calls the LLM on every tick.
