exametrika
A test-theory package that grew into a graphical-model toolkit, now spending its releases paying down the API debt that growth created.
A side-by-side editorial comparison of dqcheckr and Statsig — release velocity, themes, recent moves, and the top alternatives to consider.
dqcheckr adds drift analysis, then removes the YAML a user had to hand-write.
dqcheckr runs configurable data-quality checks over files and DuckDB tables, driven by YAML dataset configs and recording results as snapshots. The 0.2.0 release added the ability to compare two historical snapshots and report per-column statistical drift, schema changes and trend charts, extending the tool from point-in-time checking into change over time. The most recent tag, 0.3.0, attacks the other friction point by generating the config itself from a sniff pass over the data.
Statsig is packaging its own workflows as skills for someone else's agent to run.
Statsig's experimentation and feature-flag platform opened a public agent-skills repository holding reusable workflows — create dashboard, create cloud metric — written as instructions an AI agent can execute. Its MCP server extended to Segments and Layers, covering user targeting and experiment configuration, and Metrics Explorer gained the ability to abort long-running queries. The crawled feed captures marketing pages as entries, so several rows carry navigation boilerplate rather than release notes.

The most recent tag, 0.3.0, attacks the other friction point by generating the config itself from a sniff pass over the data.
Both moves point the same way: reduce what the operator has to write and know. Config generation removes the hand-authored YAML that gated first use, list_runs() and validate_config() make an existing setup inspectable, and the snapshot comparison turns accumulated run history into a second product surface. Check coverage keeps widening underneath — outlier detection, composite keys, row-count and file-size ceilings — and the reporting layer moved from rmarkdown to Quarto, with existing 0.1.x databases auto-migrated on first run.
Expect the generated configs and the drift reports to converge, so a sniffed config can seed thresholds from the snapshot history rather than from defaults, plus continued growth in the numbered QC check catalogue.

The crawled feed captures marketing pages as entries, so several rows carry navigation boilerplate rather than release notes.
The direction is agent-operated experimentation. MCP covering segments and layers means an agent can configure targeting, and the skills repository means the multi-step workflows around that configuration are distributable artifacts rather than documentation. Statsig is betting the console is not where experiments get set up much longer.
Expect the skills catalog to grow toward the analysis side — reading experiment results and proposing rollout decisions, not just creating objects. The query-abort work suggests warehouse cost control is a live concern as agent-driven usage increases.
