agentdescent vs Observer

agentdescent: AgentDescent is a parallel, asynchronous framework for evolving agent skills, prompts and harnesses, where N workers propose diffs to a shared artifact and a barrier-free aggregator merges them into a git-backed ledger. Merging uses conflict resolution, fusion and statistical acceptance rather than averaging, and the project publishes measured results and a paper.; Observer: Observer lets you build micro-agents that watch your screen, camera, microphone or clipboard and run a small local model on a loop. When the model spots a condition, JavaScript tool code sends a notification (email, Discord, Telegram, SMS, WhatsApp), records a clip or writes to memory.
