ux-flows

ux-flows is a skill for Claude Code from genkovich/sdd. It costs 216 tokens per session (2,107 once invoked), scanned A, original, MIT.

A user-flow documentation tool that maps how people move through a user-interface feature, including successful, alternative, and error paths. It uses Mermaid flowcharts, which are text-based diagrams, plus a screen inventory and an acceptance-criteria map.

In plain words
What is it for?
Use it to document one flow per UI-related user story, assign screen IDs, record the screens involved, and connect each interface requirement to a flow branch.
Why use it?
It makes the intended user journey explicit before visual design begins and shows whether every UI requirement is covered. This gives design, runtime diagrams, and end-to-end tests a shared reference.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

ux-flows 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skill: ux-flows

Draws how the user moves through a UI-touching feature — after clarify, before design. For each UI-touching §4 user story it produces a mermaid flowchart (happy path + the alt/error branches the §5 ACs demand), builds the screen inventory (SCR-NN — the id contract screens details later), and maps every UI-touching AC to the flow/branch that shows it. The artifact is always markdown + mermaid whatever docs/design-system.md picks as the drawing tool — flows are flow-altitude, not visual design. design then reads it as evidence for the target-surface + UI-architecture decisions (the formal target_surfaces declaration stays design's); sequences aligns UI-driven flows on the SCR ids; plan-tests takes the e2e-through-UI paths from here.

This stage is optional by surface, not by size: its N/A condition (no human-facing UI) lives in ../_shared/size-matrix.md and is evaluated by clarify's handoff (specify's when clarify was legally skipped). Invoked directly, it always runs.

Question phrasing → ../_shared/ask-style.md; each diagram is confirmed in prose, never as raw mermaid../_shared/diagram-presentation.md. Flow labels + prose follow artifact_language — mermaid keywords, SCR ids and AC ids stay English → ../_shared/artifact-language.md.

Owner

PM + designer (or whoever owns the user experience). The PM confirms each flow matches a real user story; the Tech Lead flags flows that imply architecture (they become design input, not decisions here).

Inputs

  • <slug> — feature slug.
  • Gate (hard-refuse if missing): docs/features/<slug>/spec.md — the flows derive from §4 user stories + §5 ACs. Absent → STOP: «run specify <slug> first — ux-flows derives from its user stories».
  • (Expected) docs/design-system.md — the platform posture (the default platform assumption) + the tool. Absent → not a block: work in code-mode assumptions, recommend /sdd:design-system in the handoff.
  • (Optional) CONTEXT.md (both levels, per-feature wins) — canonical roles for the actors.
  • (Optional) docs/features/<slug>/.size / .route — depth + handoff resolution; absent → default M / standard and say so in the handoff.

Changes

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.

ux-flows is a skill published in the GitHub repository genkovich/sdd (119 stars, last pushed yesterday), licensed MIT. It adds 216 tokens to every session and 2,107 once invoked, about $0.0011 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 2026-08-30.
