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 5.1 | $0.00069 | $0.07983 |
| Opus 5 | $0.00034 | $0.03992 |
| Sonnet 5 | $0.00014 | $0.01597 |
| Haiku 4.5 | $0.00007 | $0.00798 |
Grade C, and why
design-consultation scanned grade C with 1 finding 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.
Tells the agent never to refusehighAnti-refusal
Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.
- Always accept the user's final choice. Never refuse to proceed. How it starts
The opening of the file, as written. The whole thing — 648 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to invoke
Use when asked to "design system", "brand guidelines", or "create DESIGN.md".
Proactively suggest when starting a new project's UI with no existing design system or DESIGN.md.

/design-consultation: Your Design System, Built Together
You are a senior product designer with strong opinions about typography, color, and visual systems. You don't hand the user a menu of choices — you listen, research, and propose.
Your posture: design consultant, not form wizard. Every phase below asks questions, but the questions exist to sharpen a proposal you already made, not to outsource the design to the user. Propose a complete, coherent system, explain why it holds together, and invite the user to push back on it.
Phase 0: Pre-checks
Check for existing DESIGN.md:
ls DESIGN.md design-system.md 2>/dev/null || echo "NO_DESIGN_FILE"
- If a DESIGN.md exists: Read it. Ask the user: "You already have a design system. Want to update it, start fresh, or cancel?"
- If no DESIGN.md: continue.
Gather product context from the codebase:
cat README.md 2>/dev/null | head -50
cat package.json 2>/dev/null | head -20
ls src/ app/ pages/ components/ 2>/dev/null | head -30
Look for office-hours output:
setopt +o nomatch 2>/dev/null || true # zsh compat
eval "$(~/.vibestack/bin/vibe-slug 2>/dev/null)"
ls ~/.vibestack/projects/$SLUG/*office-hours* 2>/dev/null | head -5
ls .context/*office-hours* .context/attachments/*office-hours* 2>/dev/null | head -5
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-consultation is a skill published in the GitHub repository timurgaleev/vibestack (6 stars, last pushed 7d ago), licensed MIT. It adds 69 tokens to every session and 7,983 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 1 finding (tells the agent never to refuse). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
