Use to assess the environment against an optimal Claude Code + RDF setup: code intelligence plugins and language servers, tools, limits, sandbox, Claude Code currency, .claude files and the price table, with exact fix commands.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /rdf:r-env — Environment Assessment Assess this host against an optimal Claude Code + RDF setup for the current project: code intelligence plugins and their language servers, the tools RDF relies on, fd and process limits, sandbox dependencies, Claude Code and Codex currency, `.claude` settings and memory files, and the age of the `rdf tokens` price table. Read-only: it reports exact fixes and offers to apply them. `/rdf:r-start` shows a one-line brief of the same assessment; `rdf doctor` runs it offline as its `env` scope. This command is the full report. ## Arguments `$ARGUMENTS` (optional, any order): - `--pricing`: also compare the `rdf tokens` price table with the vendors' live pricing pages (automatic when the table is over 45 days old or a pricing finding fires) - `--offline`: no network: skip the latest-version lookups, `claude doctor` and the pricing comparison - a project path (default: the current directory) ## Protocol ### 1. Run the assessment Resolve `rdf-env.sh` (first path that exists): 1. `~/.rdf/state/rdf-env.sh` 2. `<rdf-checkout>/state/rdf-env.sh` (dev installs only) If neither exists, say the helpers are not delivered yet (plugin: restart the …

How to install
mdr add rfxn/rdf/r-env@sha256:32a348475de95352The line at the top of this page pins the label git:20261028.497294f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
