Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00022 | $0.00931 |
| Opus 5 | $0.00011 | $0.00465 |
| Sonnet 5 | $0.00004 | $0.00186 |
| Haiku 4.5 | $0.00002 | $0.00093 |
Grade A, and why
renv scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

renv
Project-local R dependency management.
Initialize Project
library(renv)
# Initialize renv in project
renv::init()
# Creates:
# - renv.lock (lockfile)
# - renv/ directory
# - .Rprofile (auto-activation)
Workflow
# 1. Initialize project
renv::init()
# 2. Work on project, install packages
install.packages("dplyr")
# 3. Snapshot dependencies
renv::snapshot()
# 4. Share project (commit renv.lock)
# 5. Collaborator restores environment
renv::restore()
Snapshot
# Snapshot current state
renv::snapshot()
# Snapshot specific packages
renv::snapshot(packages = c("dplyr", "ggplot2"))
# Snapshot with prompt
renv::snapshot(prompt = TRUE)
# Types of snapshots
renv::snapshot(type = "implicit") # Used packages only
renv::snapshot(type = "explicit") # DESCRIPTION only
renv::snapshot(type = "all") # All installed
Restore
# Restore from lockfile
renv::restore()
# Restore specific packages
renv::restore(packages = c("dplyr"))
# Clean restore (remove unlisted packages)
renv::restore(clean = TRUE)
Package Management
# Install packages
renv::install("dplyr")
renv::install("tidyverse")
# Install from GitHub
renv::install("tidyverse/dplyr")
# Install specific version
renv::install("[email protected]")
# Install from local source
renv::install("./path/to/package")
# Update packages
renv::update()
renv::update("dplyr")
# Remove packages
renv::remove("unused_package")
Status and Diagnostics
# Check status
renv::status()
# View dependencies
renv::dependencies()
# Check for issues
renv::diagnostics()
# View lockfile
renv::lockfile_read()
Lockfile
# View lockfile contents
lockfile <- renv::lockfile_read()
lockfile$Packages
# Modify lockfile
renv::record("[email protected]")
# Validate lockfile
renv::lockfile_validate()
Configuration
# Settings in .Rprofile or renv/settings.dcf
# Use binary packages
renv::settings$use.cache(TRUE)
# Set repository
renv::settings$repos(c(CRAN = "https://cloud.r-project.org"))
# Ignore packages
renv::settings$ignored.packages(c("devtools"))
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

renv is a skill published in the GitHub repository LeoLin990405/r-analytics-skill (5 stars, last pushed 5mo ago), licensed MIT. It adds 22 tokens to every session and 931 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
