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 | $0.00056 | $0.01134 |
| Opus 5 | $0.00028 | $0.00567 |
| Sonnet 5 | $0.00011 | $0.00227 |
| Haiku 4.5 | $0.00006 | $0.00113 |
Grade A, and why
design-fundamentals 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 12d 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.

Design Thinking Fundamentals
For Claude: This skill provides foundational design thinking knowledge to help users understand the Design Partner workflow and methodology.
Core Design Thinking Process
Design Partner follows a structured 5-phase approach:
1. Context Capture
- Goal: Gather essential problem context
- Questions: Who is this for? What job needs to be done? What constraints matter?
- Output: Design Brief with problem, users, constraints, and success criteria
2. Divergent Exploration
- Goal: Generate multiple solution directions
- Approach: Explore different assumptions, perspectives, and approaches
- Output: 5+ idea cards with diverse core assumptions
3. Convergent Selection
- Goal: Choose the most promising direction(s)
- Approach: Evaluate ideas based on feasibility, desirability, and viability
- Output: Selected idea(s) for deeper exploration
4. Visualization & Prototyping
- Goal: Create concrete artifacts to explore the idea
- Approach: Generate UI mockups, concept art, user scenarios
- Output: High-resolution images via DALL-E 3 or Gemini Imagen
5. Critique & Iteration
- Goal: Identify risks and refine the approach
- Approach: Systematic risk analysis and rapid iteration
- Output: Refined concept with addressed concerns
Ideation Techniques
Divergent Thinking (Broadening)
- Reframe the problem from different perspectives
- Challenge core assumptions
- Explore extreme constraints or inversions
- Consider different user types or contexts
Convergent Thinking (Narrowing)
- Evaluate based on impact and feasibility
- Force-rank options
- Identify must-have vs nice-to-have features
- Select direction based on success criteria
Visual Exploration
Natural Language
Simply say "show me what this looks like" and Design Partner will:
- Extract context from your conversation
- Build an enhanced prompt from your Design Brief
- Generate a high-resolution image
- Link it to your design session
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-fundamentals is a skill published in the GitHub repository danielraffel/generous-corp-marketplace (11 stars, last pushed 13d ago), licensed MIT. It adds 56 tokens to every session and 1,134 once invoked, about $0.0003 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.
