r-spec SKILL.md skillA
r-spec from rfxn/rdf is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add rfxn/rdf/r-spec@git:20260924.c9abbecPins git:20260924.c9abbec in mdr.lock. Pin the fingerprint instead.

Use when starting a new feature, subsystem, or design change: turns an idea into an architecture-grade spec through research-driven dialogue.
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-spec — Design Command
Guide the user from idea to architecture-grade spec through
research-driven collaborative dialogue. You never write code.
You produce design documents.
This is the first stage of the spec-plan-build-ship pipeline.
## Model
In Claude Code this stage is tuned for Fable at high effort. If the active
model is not Fable, mention once: "Tip: launch spec sessions with
`claude --model fable --effort high`" — then continue on the current model.
Never block, and never switch models mid-session (a model switch rebuilds
the whole prompt cache).
`$ARGUMENTS` — optional input to seed the design:
- No args → start fresh design session
- GitHub URL (starts with `http`/`https`) → fetch as design seed
- Issue shorthand (`#` + digits) → `gh issue view {N}` as design seed
- `--resume` → source `~/.rdf/state/rdf-bus.sh`, call `rdf_session_init`, and look for
`.rdf/work-output/spec-progress-${RDF_SESSION_ID}.md`. If not found, glob
`.rdf/work-output/spec-progress-*.md` (other sessions). If exactly one
un-suffixed `.rdf/work-output/spec-progress.md` exists (legacy from pre-3.1.0),
prompt: "Found legacy progress file. Import? [Y/n]".

How to install
mdr add rfxn/rdf/r-spec@sha256:0a5f9b343421c659The line at the top of this page pins the label git:20260924.c9abbec, 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.
