Kin-Code is a terminal-based AI coding assistant written entirely in Go, born from the chaos of Anthropic's accidental Claude Code source code leak on March 31, 2026. The project is a ground-up reimplementation that ships as a single 9MB binary with zero runtime dependencies — no Node.js, no Python, no package manager required. The tool supports multiple provider backends (Anthropic, OpenAI, Ollama), making it fully functional with local models. It packs ten built-in tools including bash execution, file operations, web search, and memory management. Unique features like "Soul files" let you define persistent AI personas per project, while a sub-agent system enables parallel task execution. Context auto-compression and extended thinking mode are also included out of the box. Where Kin-Code earns its place is on constrained environments: servers, CI runners, or dev containers where a 250MB Node runtime isn't welcome. The timing is deliberately provocative — shipping a leaner, provider-agnostic alternative to Claude Code within days of the leak positions it squarely against Anthropic's own tool while running on Anthropic's API.

Metrics SQL by Rill
One SQL semantic layer so AI agents stop hallucinating your KPIs

Metrics SQL is a SQL-based semantic layer from Rill Data that solves a specific and painful problem: AI agents that query your data warehouse tend to hallucinate aggregation logic, producing metrics that look plausible but are mathematically wrong. Metrics SQL lets analysts define business metrics once — revenue, MAU, conversion rate, ROAS — in a governed definition layer, and then exposes those definitions as queryable SQL tables. Every dashboard, notebook, and AI agent resolves from the same source. The technical approach is elegant: rather than inventing a new DSL, Metrics SQL extends SQL itself. An agent that knows SQL can query `SELECT * FROM metrics.weekly_revenue` and get correctly computed numbers without needing to know how revenue is defined, which tables it joins, or how edge cases like refunds are handled. The semantic layer intercepts the query, applies the governed definition, and returns correct results. The implications for AI-native data stacks are significant. Currently, one of the biggest failure modes for AI analysts and BI agents is inconsistent metric computation — different agents or dashboards produce different numbers for 'revenue' because they implement aggregation logic differently. Metrics SQL addresses this at the infrastructure level, not by improving agent prompting.
Reviewer scorecard
“A single binary that does what Claude Code does but works with Ollama too? That's a genuine win for teams running air-gapped or resource-constrained environments. The Go implementation means cross-platform distribution without dependency hell — just download and run.”
“We've been burned by data agents that invent their own GROUP BY logic and produce wrong numbers that look right. Metrics SQL solves this at the infrastructure level — define revenue once, have every agent query the same definition. The SQL-native interface means no new tools for agents to learn; they just use the tables.”
“Built in days by a small team as a direct response to a leak — that's a product with unclear maintenance commitment. The feature parity claim is aggressive for something that fast-follows a 512K-line codebase. Wait and see if LocalKin actually supports this long-term before betting a workflow on it.”
“The value here is only as good as how well-maintained your metric definitions are — if analysts don't keep them updated, agents query stale or wrong definitions and you've added a layer of false confidence. Adopting a semantic layer also creates vendor dependency; migrating away from Rill's cloud later is a real switching cost. For smaller teams without dedicated data engineering, maintaining a semantic layer is overhead.”
“This is exactly how open ecosystems evolve — a leak democratizes a design, and within 72 hours there are lighter, more flexible reimplementations. Kin-Code's multi-provider support and Soul files hint at a future where coding agents are as composable as Unix tools.”
“Data governance and AI agents are on a collision course. As more business decisions are delegated to AI, the correctness of KPI computation becomes load-bearing — a hallucinated revenue figure that influences a product decision is a serious failure mode. Metrics SQL represents a class of infrastructure that will become mandatory as AI takes on more analytical work.”
“For solo developers and indie builders who hate bloated toolchains, a 9MB binary that just works is a breath of fresh air. The Soul files feature for custom personas is genuinely interesting for maintaining consistent AI voice across projects.”
“I rely on AI to pull weekly performance data, and the number of times it's given me different 'correct' answers for the same metric is maddening. Having a single governed source that every AI query resolves against means I can trust the numbers I'm making decisions on. That trust is worth a lot.”
