Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00078 | $0.01478 |
| Opus 5 | $0.00039 | $0.00739 |
| Sonnet 5 | $0.00016 | $0.00296 |
| Haiku 4.5 | $0.00008 | $0.00148 |
Grade A, and why
sddesign 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 5d 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 — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Context: this sub-skill is one lens of the broader ui-craft skill. If the ui-craft skill is also installed, read its SKILL.md first for Discovery + Anti-Slop + Craft Test, then apply the specific lens below.
Run the spec-driven design pipeline for $ARGUMENTS. Load the ui-craft skill.
ORCHESTRATE-ONLY RULE
This command sequences existing phase commands. It MUST NOT re-implement or duplicate any logic from them. Every composition rule, wireframe algorithm, craft rule, and convergence engine lives in the phase commands. This command contributes only:
- Gate detection (does the artifact exist?)
- Offer prompts (run phase X or skip?)
- Progress reporting (the checklist)
- Degraded-mode honesty (what was skipped and what that costs)
When in doubt: call the phase command, don't inline its steps.
Progress Checklist
Print this at the start and update it after each gate resolves:
[ ] brief [ ] tokens [ ] shape (spec) [ ] craft (build) [ ] converge [ ] ship
Use [✓] for completed/skipped-with-artifact, [>] for the current gate, [–] for skipped-without-artifact (degraded).
Pipeline Gates
Gate 1 — Brief
Check: does .ui-craft/brief.md exist?
If yes: mark [✓] brief. Note that brief §6 learned constraints and the a11y/correctness floor are in effect for all downstream gates — they take precedence over any spec.md composition choice.
If no: offer to run /brief now.
- User confirms → run
/brief. When it completes, mark[✓] brief. - User declines → mark
[–] brief. Note downstream impact: "no brief → craft will use skill defaults; composition will not be anchored to project principles."
Gate 2 — Tokens
Check: does a token spine exist? (Look for CSS variables --color-*, --font-*, --accent-*, a Tailwind theme.extend with tokens, or a token file.)
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.

sddesign is a skill published in the GitHub repository educlopez/ui-craft (310 stars, last pushed yesterday), licensed MIT. It adds 78 tokens to every session and 1,478 once invoked, about $0.0004 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.
