What it does
Literate R Formats is an agent skill from r-lib/lintr. Guidelines and architecture for handling literate R documents (.Rmd, .qmd, .Rnw, .Rhtml, .Rtex, .Rrst, .Rtxt) and source extraction in the r-lib/lintr package. Use when modifying R/extract.R, R/getsourceexpressions.R, or tests/testthat/test-knitrformats.R. Don't use for standard .R file linters that do not interact with chunk extraction.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Linting and formatting. The repository describes itself as: Static Code Analysis for R.
When your agent uses it
- Modifying R/extract.R
- R/getsourceexpressions.R
- Tests/testthat/test-knitrformats.R
- Standard .R file linters that do not interact with chunk extraction
Example prompts
- “Use the literate-r-formats skill to guideline and architecture for handling literate R documents (.Rmd, .qmd, .Rnw, .Rhtml, .Rtex, .Rrst, .Rtxt) and…”
- “/literate-r-formats”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Line & Column Preservation via NA_character_ & Prefix Masking
- Chunk Bounds & eval=FALSE Filtering
- Engine Detection
- Multi-Format Testing Conventions (tests/testthat/test-knitr_formats.R)
What it can do on your machine
Read from SKILL.md and the folder at commit 6dda4e3. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are r).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Literate R Formats loads about 1k tokens when it runs. Until then it costs about 96 tokens; SKILL.md has 339 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 339 words (~1,046 tokens).
“When modifying how lintr extracts R source code from literate programming and multi-language documents (RMarkdown .Rmd, Quarto .qmd, Sweave .Rnw, HTML .Rhtml, LaTeX .Rtex, reST .Rrst, or AsciiDoc .Rtxt), adhere to the following architectural conventions in R/extract.R:”
