ux-foundations

ux-foundations is a skill for Claude Code, Codex from zeeshanhanif/agentic-sdlc-kit. It costs 212 tokens per session (2,277 once invoked), scanned A, original, Apache-2.0.

A foundation-building workflow for an application's user experience and visual language before feature work starts. It uses product requirements and architecture documents when available.

In plain words
What is it for?
Use it to establish design rules for websites, mobile apps, admin portals, and other interfaces before screens are assembled.
Why use it?
It prevents each screen or interface from developing its own unrelated navigation, components, and accessibility decisions. It creates a shared design system while allowing different user-facing surfaces to have their own needs.

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-foundations 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 7d 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.

UX Foundations

This skill defines the structure and design language of the UI before any feature is built — the counterpart to a software-architecture document, but for the experience layer. It produces the system screens are later assembled from, not pixel-perfect screens.

The governing idea, especially with several interfaces: one shared core, defined once, plus a per-surface layer for each interface. A single design language spans every surface so the product feels like one thing; each surface (admin portal, website, mobile app) gets its own profile because its users, navigation, components, and context genuinely differ.

Inputs

Two kinds of input with different consumption rules:

Pipeline documents — read silently, never ask. These are this pipeline's own upstream artifacts in their contracted locations; consuming them is the pipeline working as designed.

  • SRS — default docs/srs.md. Read §2.3 (user classes & characteristics — the personas source; do not re-elicit them), §1.2 (vision/scope), the accessibility/usability NFRs in §3.3 (the accessibility bar comes from here and is non-negotiable — it overrides any ingested design), and any brand/compliance constraints in §2.5. Note NFR IDs for citation.
  • Architecture — default docs/architecture.md. Read the UI surfaces (they appear as containers/building blocks), the context diagram's actors, and any frontend stack constraints.
  • Use casesdocs/use-cases.md if present: key user flows often realize use cases; cite UC IDs where they do.

Source-gated traceability (same rule as the architecture skill): cite SRS NFR/FR IDs and UC IDs only when those documents exist; otherwise state drivers in prose. Never fabricate an ID.

Design source — always ask, never assume. Detection tells you what's possible; only the user can tell you what's wanted. A design.md in the folder may be stale; images may be leftovers; the user may want a fresh direction despite having sources. See Phase 1.

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.
