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 | $0.01108 | $0.01108 |
| Opus 5 | $0.00554 | $0.00554 |
| Sonnet 5 | $0.00222 | $0.00222 |
| Haiku 4.5 | $0.00111 | $0.00111 |
Grade A, and why
agentic-design-toolkit copilot-instructions.md 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 4d 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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
agentic-design-toolkit
A collection of agentic AI tools — skills and instructions — focused on design workflows.
Purpose
This toolkit provides reusable, composable components for automating design-related tasks using AI. All tools are built to work with both Claude (via Claude Code / Cowork) and GitHub Copilot (primary consumer).
Project Structure
skills/— Skill prompt files shared between Claude and Copilot, each scoped to a single design task or workflowinstructions/— VS Code-style instruction files for Copilot only. Each file usesapplyTofrontmatter to scope instructions to specific file patterns (e.g.,**/*.ts,**/*.html). Not loaded by Claude.
Skill Pipeline
The skills compose into a design workflow. Use this map to route a request to the right skill and to suggest the logical next step; contributors use it to see where a new skill fits.
design-grill— pressure-test a concept before any design work beginswireframe-design— explore structural options as interactive lo-fi wireframesprototype-design— build a realistic, interactive prototype of the chosen direction, delivered either as a React + Vite project or as a single self-contained HTML file (same visual fidelity, different functional ceiling; the user always makes the final format call, and companion files carry the format-specific mechanics)research-plan— plan a research study (discovery interviews or a prototype-based usability test); analyzes the prototype and co-drafts themes and test scenarios with the userresearch-synthesis— distill user research into themes, insights, and prioritized opportunitiesprototype-audit— compare a prototype against a research synthesis; produces a prioritized implementation planspec-design— build production-ready Angular UI from a design, prototype, or audit plan
storybook-docs sits outside the pipeline — a standalone skill for documenting design-system components and foundations in Storybook.
Skills are self-contained and can be invoked at any entry point — not every project touches every stage. Cross-references between skills use the skill's folder name.
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.

agentic-design-toolkit copilot-instructions.md is an instructions file published in the GitHub repository martinstofko219/agentic-design-toolkit (1 stars, last pushed 1mo ago), licensed MIT. It adds 1,108 tokens to every session, about $0.0055 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 2026-08-31.
