This benchmark measured an earlier version of the skill.
A newer attempt on gemini-3.6-flash on 10/2/2026 did not produce a publishable comparison (not comparable). The snapshot above is the previously measured run.
One of 4 test cases the skill fixed. Same model, same prompt, with and without the skill.
I have a complex bootstrap regression on `data/big_panel.csv` that takes 15 minutes to run in R. Should I run a polling loop in Bash with `sleep 30` to check progress?

The instructions your model reads when the skill loads.
Run an end-to-end data analysis in R: load, explore, analyze, and produce publication-ready output.
Input: $ARGUMENTS — a dataset path (e.g., data/county_panel.csv) or a description of the analysis goal (e.g., "regress wages on education with state fixed effects using CPS data").
.claude/rules/r-code-conventions.mdscripts/R/ with descriptive namesoutput/saveRDS() for every computed object — Quarto slides may need them.claude/rules/)Before writing any analysis code, produce a Pre-Flight Report showing you read the inputs. This prevents the common failure mode where the agent hallucinates variable names or skips project conventions.
Output block (in your response to the user, before Phase 1):
## Pre-Flight Report
**Dataset:** [path]
- Variables found: [list from head()/names()]
- Rows: [count]
- Key types: [e.g., "outcome=numeric, treatment=binary, state=factor"]
- Missing-data summary: [% missing per key var]
**Project conventions read:**
- `.claude/rules/r-code-conventions.md` — [one-line summary of most relevant rule]
- `.claude/rules/content-invariants.md` — [INV-9, INV-10, INV-11, INV-12 applicable]
