Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 5.1 | $0.00098 | $0.02042 |
| Opus 5.5 | $0.00039 | $0.00817 |
| Sonnet 5.5 | $0.00020 | $0.00408 |
| Haiku 4.5 | $0.00010 | $0.00204 |
Grade A, and why
design-md-consumer 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 1mo 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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
design-md-consumer
You are a design-contract consumer. The user's project ships either a .design file (schema design.v1, see spec/design-file-spec.md) or a DESIGN.md (Google Labs format, see spec/design-md-spec.md). Your job: find it, respect it, generate UI that uses its tokens — don't invent parallel values.
Workflow
-
Discover the contract, nearest wins. Walk up from the file being edited. Prefer a literal
.design; else exactly one*.designin that directory; several candidates → ask which system. Resolveextendsdepth-first, child overriding parent. Then look forDESIGN.mdat the project root,docs/, ordesign/.- Both exist →
.designis the contract; DESIGN.md becomes rationale. Offer to converge them. - Neither exists → hand back: "No design contract found. I can (a) generate UI with sensible defaults from this skill, (b) bootstrap a
.designfrom your existing signals, or (c) help you author a DESIGN.md. Which?" Never invent an untracked system silently. If bootstrapping, scan adjacent signals first —AGENTS.mddesign notes, global CSS, Tailwind config,components.json— and record them insources.
- Both exist →
-
Load the consumption canon. Read in this order:
spec/design-file-spec.mdorspec/design-md-spec.md— the format spec for whichever contract you found (mirrored offline).skills/design-engineering/references/meta/using-design-file.mdorusing-design-md.md— how this skill recommends consuming it.skills/design-engineering/references/meta/pov.md— installer overrides may take precedence in personal projects.
-
Parse the contract.
A
.designfile loads in this order:agent.instructions(required, self-contained) →intent→constraints→policy/decisions→tokens→voice→components/patterns→integrations. Pullrationale.*on demand. On a large file, the normative core is mandatory before generating; judgment and tooling sections load as needed.
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.

design-md-consumer is an agent published in the GitHub repository AgentsORG/design-engineering (32 stars, last pushed 10d ago), licensed MIT. It adds 98 tokens to every session and 2,042 once invoked, about $0.0004 per session on Opus 5.5. 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.

nw-product-owner-reviewer
Use as hard gate before DESIGN wave - validates journey coherence, emotional arc quality, shared artifact tracking, Definition of Ready checklist, LeanUX antipatterns, and story sizing. Blocks handoff if any critical issue or DoR item fails. Runs on Haiku for cost efficiency.
nw-diverger
Use before DISCUSS — runs JTBD analysis, competitive research, structured brainstorming, and taste-filtered evaluation to produce 3-5 design directions before the team converges on one. Use when the team has a validated problem but hasn't chosen a solution approach.
