What is tidyprompt?

An R prompting framework hands its provider plumbing to ellmer and inherits MCP tools

tidyprompt composes LLM prompts out of stackable 'prompt wraps' — answer_as_json(), answer_as_category(), answer_using_tools() — and validates what comes back. Its recent history is one decision: stop maintaining a provider layer. llm_provider_ellmer() arrived experimental, then became the path through which structured output, tool calling and streaming are done natively. The newest release adds dataframe and numeric extraction wraps and lets send_prompt() take an ellmer chat object directly.

What is vcmeta?

A meta-analysis toolkit still renaming its own API as it adds effect sizes.

vcmeta provides confidence-interval methods for meta-analysis across correlations, proportions, odds ratios, standardized mean differences and reliability, plus replication-study counterparts to most of them. Each release both widens the function inventory and reshuffles it. The most recent one adds agreement and generalised log-average functions while deleting one function and renaming six others.

An R prompting framework hands its provider plumbing to ellmer and inherits MCP tools

◆ Current state

tidyprompt composes LLM prompts out of stackable 'prompt wraps' — answer_as_json(), answer_as_category(), answer_using_tools() — and validates what comes back. Its recent history is one decision: stop maintaining a provider layer. llm_provider_ellmer() arrived experimental, then became the path through which structured output, tool calling and streaming are done natively. The newest release adds dataframe and numeric extraction wraps and lets send_prompt() take an ellmer chat object directly.

◆ Where it's heading

Two lines run together. One is catalogue growth — every release adds a wrap for another answer shape. The other is consolidation onto ellmer, and that is where the leverage is: because ellmer tool definitions are what mcptools::mcp_tools() returns, tidyprompt gained access to Model Context Protocol servers without writing an MCP client. Its own Gemini provider is already marked superseded. Note the feed's stamps lie — 0.1.0, 0.2.0 and 0.3.0 were all published within two hours of each other in reverse version order.

◆ Prediction

The remaining first-party providers are the obvious next thing to fold in: the Gemini one is already superseded, and the Ollama and OpenAI providers carry the same duplicated plumbing. Expect the wrap catalogue to keep growing on top of an increasingly ellmer-only base.

A meta-analysis toolkit still renaming its own API as it adds effect sizes.

◆ Current state

vcmeta provides confidence-interval methods for meta-analysis across correlations, proportions, odds ratios, standardized mean differences and reliability, plus replication-study counterparts to most of them. Each release both widens the function inventory and reshuffles it. The most recent one adds agreement and generalised log-average functions while deleting one function and renaming six others.

◆ Where it's heading

The package is converging on a naming scheme, with odds becoming oddsratio and ratio.prop2 becoming propratio2, and it is willing to break calling code to get there. Two of the last three releases carry a self-declared breaking parameter change, both cases where an assumption that used to be baked in became something the user must supply. Growth in the function set is steady rather than directional.

◆ Prediction

Expect the renaming pass to continue into the remaining inconsistent names, alongside more replication-study counterparts to existing estimators.
