/riff

Produce 2 or 3 clickable mock variants. Each pins a luminary lens. Three modes — full, local, scratch. Full uses git, gh, and screenshots. Local writes to disk only. Scratch uses a tmp dir with no git.

Copy the command
/riff
/riff full
/riff local
/riff scratch

Type it bare, or paste it with loose context after — Claude figures out the rest.

Solves

Design work gets one variant. No comparison. The operator picks blind. Rework is heavy.

Payoff

Two or three mocks per surface. Each mock pins a luminary lens. Cold adopters see a result in five minutes.

Takes in

  • A UI surface intent or design goal

Returns

  • 2-3 clickable mock variants
  • Luminary lens per variant

You get 2-3 clickable mock alternatives for a UI surface. Each mock uses a different luminary lens. You pick the one that fits.

The picker picks a marketing variant. The writer picks a direction before building.

FAQ

Terms from bassclef vocabulary that appear on this page.

luminary
A design or engineering thinker whose discipline bassclef borrows as a review lens — the practitioner in the cameo pattern above. Cooper for personas, Norman for signifiers, Feathers for characterization tests, Beck for TDD rhythm, plus about 90 others. Skills invoke a lens to check work against a specific discipline. `/luminary` browses the catalog. See: /docs/skills/luminary, doi:10.5281/zenodo.22145491
rule
A markdown file auto-loaded into every session's context. Rules pin discipline the agent applies to every response (plain-English writing, blocked-items protocol, temperance gates). Different from a hook — rules are steering; hooks are enforcement.
skill
A user-invocable command (like `/kiss` or `/temperance`) that runs a specific bassclef workflow. Every skill lives at `.claude/skills/<name>/SKILL.md` with frontmatter + procedure. Adopters type the slash command; Claude Code loads the skill and runs it.
adopter
A repo that has bassclef installed — either via `bassclef init` (lite tier from npm) or via the symlink pattern (standard tier with an Anthropic key). Bassclef's discipline: never break adopters. Every change to a downstream-observable surface ships with a compat shim.
bassclef-upstream
The private repo where bassclef substrate is authored. Ships to a public `bassclef` npm package + a public `bassclef-web` docs site. Adopters read the public tier; the operator maintains upstream.
