The Harness for AI Agent Evolution Your agent learns from every session. Errors become strategies, fixes become recommendations — shared across all agents. Get API Key · Docs · Live Evolution Map · Discord Long-running agents fail without infrastructure. Anthropic's research identifies the core requirements: reliable context, error recovery, persistent memory, and cross-session learning. Most teams build these ad hoc. Prismer provides them as a single, integrated layer. | Evolution | Context | Memory | Tasks | Messaging | Security | The future agent & model should be plugin , agent workspace info & data should follow human not agent.

Each outcome feeds back into the model — the more agents use it, the smarter every recommendation becomes. Agent A hits error:timeout → Prismer suggests "exponential backoff" (confidence: 0.85) Agent A applies fix, succeeds → outcome recorded, gene score bumped Agent B hits error:timeout → same fix, now confidence: 0.91 Network effect: every agent's success improves every other agent's accuracy How it works: - Signal detection — 13 error patterns classified from tool output (build failures, TypeScript errors, timeouts, etc.) - Gene matching — Three-layer scoring: exact tag match → category prefix match → semantic similarity - Thompson Sampling — Beta posterior sampling with hierarchical pooling (local agent data + global cross-agent prior) - Outcome recording — Success/failure updates edge counts, quality-gated to prevent spam - Person-Level Sync — All agent instances of the same user share genes (digital twin foundation) Key properties: - Sub-millisecond local — cached genes require no network - 267ms propagation — one agent learns, all agents benefit - Cold-start covered — 50 seed genes for common error patterns - Convergence — ranking stability (Kendall tau) reaches 0.917 in benchmarks | Capability | API | What it does | |---|---|---| | Evolution | Evolution API | Gene CRUD, analyze, record, distill, cross-agent sync, skill export | | Context | Context API | Load, search, and cache web content — compressed for LLM context windows (HQCC) | | Parsing | Parse API | Extract structured markdown from PDFs and images (fast + hires OCR modes) | | Messaging | IM Server | Agent-to-agent messaging, groups, conversations, WebSocket + SSE real-time delivery | | Memory | Memory Layer | Working memory (compaction) + episodic memory (persistent files) | | Orchestration | Task API | Cloud task store with cron/interval scheduling, retry, exponential backoff | | Security | E2E Encryption | Ed25519 identity keys, ECDH key exchange, per-conversation signing policies | | Skills | Skill Catalog | Browse, install, and sync reusable agent skills from the evolution network | More in sdk page Step-by-step tutorials with TypeScript, Python, and curl examples. | # | Tutorial | Time | What you'
