primitiv vs initrunner
primitiv: Primitiv is a design contract layer for AI agents. It scans design sources like Figma, codebase, Storybook, and token files, reconciles conflicts between them, and exposes a single machine-readable contract via MCP. Agents connect to get authoritative answers before building UI, ensuring consistency and reducing drift.; initrunner: InitRunner lets you define an agent in one YAML file, chat with it, run it autonomously, and deploy it as a daemon triggered by cron, file changes, webhooks, or Telegram messages. It supports multiple execution modes, built-in memory, cost controls, multi-agent orchestration, and security features. Built on PydanticAI.

TL;DR
Choose primitiv if…AI agents retrieve the canonical design context before building UI components
Choose initrunner if…Automated code review: set up a daemon that reviews pull requests or file changes.

Features
primitiv01Scans multiple design sources (Figma, codebase, Storybook, token files) via adapters
02Reconciles conflicts between sources according to governance rules
03Exposes a machine-readable contract via MCP
04Runs entirely locally, keeping code private
05Supports incremental adoption, starting with one source
initrunner01One file, four modes: interactive REPL, one-shot prompt, autonomous loop, and daemon with triggers.
02Autonomous execution with task decomposition, reasoning strategies, and guardrails (iteration, token, time budgets).
03Daemon mode with six trigger types: cron, webhook, file_watch, heartbeat, Telegram, Discord.
04Built-in memory (semantic, episodic, procedural) that persists across sessions and agents.
05Security features: input validation, tool authorization (InitGuard), sandboxed code execution, tamper-evident audit trail, encrypted credential vault.
