Artificial Intelligence Workflow Tools.
wf 
wf manages skills for AI coding agents. Skills are reusable instruction sets that extend what an agent can do. They live in a conventional directory for each agent (e.g., .claude/skills/ for Claude Code) and can be installed from GitHub or a local path.
Installation
# install.packages('pak')
pak::pak('christopherkenny/wf')
Setup
Set WF_AGENT in your .Renviron so every wf function knows which agent you use:
usethis::edit_r_environ()
Add a line like:
WF_AGENT='claude_code'
Supported agents: 'claude_code' (alias: 'claude'), 'openclaw', 'codex', 'cursor', 'gemini_cli', 'github_copilot' (alias: 'copilot'), 'posit_ai' (alias: 'posit').
Skills can be scoped to a project (.agent/skills/) or installed globally (~/.agent/skills/):
library(wf)
skill_path('claude_code', 'project') # project-local
#> [1] ".claude/skills"
skill_path('claude_code', 'global') # user-global
#> [1] "~/.claude/skills"
skill_path() # auto-detected from WF_AGENT or directory
#> [1] ".claude/skills"
Example
Install a skill from GitHub using its owner/repo shorthand or a full URL:
add_skill('some-user/some-skill')
For repos that bundle multiple skills, use the skill argument:
add_skill('some-user/skills', skill = 'proofread')
List, check, and update installed skills:

#> .claude/skills/cran-extrachecks Prepare R packages for CRAN submission by checking for common ad-hoc requirements not caught by devtools::check(). Use when: (1) Preparing a package for first CRAN release, (2) Preparing a package update for CRAN resubmission, (3) Reviewing a package to ensure CRAN compliance, (4) Responding to CRAN reviewer feedback. Covers documentation requirements, DESCRIPTION field standards, URL validation, examples, and administrative requirements.\n
#> .claude/skills/tidy-argument-checking Validate function inputs in R using a standalone file of check_* functions. Use when writing exported R functions that need input validation, reviewing existing validation code, or when creating new input validation helpers.
#> .claude/skills/tidy-deprecate-function Guide for deprecating R functions/arguments. Use when a user asks to deprecate a function or parameter, including adding lifecycle warnings, updating documentation, adding NEWS entries, and updating tests.
