OpenSquilla open-sources a microkernel agent with local four-tier model routing

@DanKornas highlighted TokenRhythm/opensquilla, a token-efficient microkernel AI agent for builders. SquillaRouter scores each turn locally on length, language, code, keywords, and semantic embeddings, then routes across four tiers to the cheapest capable model; the registry targets 20+ LLM backends with primary-plus-fallback. Fifteen bundled skills load on demand, and the agent can act as an MCP client or server. Local Markdown notes add SQLite full-text search and sqlite-vec semantic recall, with three sandbox policy tiers plus human-in-the-loop approvals for sensitive tools. Apache 2.0.
