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.

Superpowers is a sophisticated agentic coding framework and software development methodology created by Jesse Vincent at Prime Radiant. Rather than giving AI agents a blank slate, it enforces a structured workflow: agents brainstorm with stakeholders, write detailed specs, break work into 2–5 minute bite-sized tasks, then execute via parallel subagents with automated code review and test-driven development baked in. The framework runs natively on Claude Code, GitHub Copilot CLI, Cursor, Gemini CLI, and other coding agents. Its 45+ composable skills — written primarily in Shell and JavaScript — cover everything from debugging and refactoring to creating new skills on the fly. Git worktrees keep branches isolated so parallel agents don't step on each other during concurrent work. With 188,000+ GitHub stars (trending today with +1,400 in a single day) and 440+ commits, Superpowers has quietly become one of the most-starred agentic methodology repos on GitHub. MIT-licensed and available through multiple plugin marketplaces, it bolts cleanly onto existing development workflows without a major toolchain change.
Reviewer scorecard
“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.”
“If you've ever watched Claude Code spiral into confusion after three tool calls, Superpowers is the antidote. The spec-before-code workflow eliminates most context loss, and the parallel subagent model actually ships features faster than one monolithic agent thrashing around. Worth the upfront ceremony.”
“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.”
“188k GitHub stars sounds impressive until you remember star farming is rampant in 2026. The methodology requires agents to ask clarifying questions upfront — great in theory, genuinely annoying when you just want a one-line bug fixed. Adds process overhead that not every team will want.”
“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.”
“Superpowers is a glimpse of how software will be built at scale: not by individual programmers, not by lone AI agents, but by coordinated swarms of specialised subagents following deterministic specs. The methodology here may outlast any specific underlying model.”
“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.”
“Finally a way to actually delegate an entire feature without babysitting the AI every ten minutes. The structured brainstorm phase means the agent asks dumb questions before writing code — not after — which is a huge quality-of-life improvement.”
