What is projoint?

projoint spent a year on CRAN paperwork, then shipped a correctness fix it flagged itself.

projoint is an R package for analysing conjoint survey experiments, covering Qualtrics import, reshaping, and quantity-of-interest estimation with inter-rater reliability correction. Most of its release history is CRAN admission work — citation formats, DESCRIPTION fields, \value{} tags, vignette cleanups — with four tags backfilled within ninety seconds of each other on 15 July in non-monotonic version order, so neither tag order nor timestamps in this feed track the real sequence. The substantive releases are the ones fixing data-preparation bugs that silently corrupt estimates.

What is Statsig?

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.

projoint spent a year on CRAN paperwork, then shipped a correctness fix it flagged itself.

◆ Current state

projoint is an R package for analysing conjoint survey experiments, covering Qualtrics import, reshaping, and quantity-of-interest estimation with inter-rater reliability correction. Most of its release history is CRAN admission work — citation formats, DESCRIPTION fields, \value{} tags, vignette cleanups — with four tags backfilled within ninety seconds of each other on 15 July in non-monotonic version order, so neither tag order nor timestamps in this feed track the real sequence. The substantive releases are the ones fixing data-preparation bugs that silently corrupt estimates.

◆ Where it's heading

The maintainer is hardening the path from raw Qualtrics export to estimate, which is where conjoint analysis quietly goes wrong. Three separate releases fix that path: dropped respondent-level weights in organize_data(), repeated-task reshaping in reshape_projoint(), and choice-to-profile mapping in 1.1.3. Each fix now arrives with regression tests and stricter validation rather than just a patch, and 1.1.3 adds an explicit .choice_map so the mapping is auditable instead of inferred.

◆ Prediction

Expect the validation-and-regression-test pattern to keep extending across the import path, with releases continuing to arrive in bursts around CRAN submission rather than on a cadence.

Statsig is packaging its own workflows as skills for someone else's agent to run.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.
