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 | $0.00049 | $0.00731 |
| Opus 5 | $0.00024 | $0.00365 |
| Sonnet 5 | $0.00010 | $0.00146 |
| Haiku 4.5 | $0.00005 | $0.00073 |
Grade A, and why
design-perspective 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.

Design Perspective
Core Philosophy
Design is not a phase — it is a perspective applied across all product processes.
| Process | Design's Role |
|---|---|
| Opportunity Discovery | Journey maps, pain point visualization |
| Solution Generation | Design principle-driven ideation |
| Assumption Validation | Prototype generation → usability testing |
| PRD Definition | Usability risk confirmation for user stories |
| Reflection | UX learning accumulation |
Design Principles Reference
Reference only the product-specific principles from docs/product/design-principles.md that can change the current design decision.
Design principles are product-specific guardrails that guide all design decisions. They are not generic best practices but choices that reflect this product's values and trade-offs.
State Design
State Design checks Loading, Empty, Error, Partial, and Success, then specifies the states that can change observable behavior or verification.
In practice:
- PRDs specify applicable state behavior and preserve an exclusion reason when omission would be ambiguous
- Prototypes implement the states needed to test the hypothesis
- User stories addressing Usability risk should consider all relevant states
Accessibility Standards
Baseline: WCAG 2.2 AA compliance
Key requirements:
- Perceivable: Text alternatives for non-text content, sufficient color contrast (4.5:1 for normal text, 3:1 for large text), content adaptable to different presentations
- Operable: All functionality available via keyboard, sufficient time for interactions, no content that causes seizures, clear navigation mechanisms
- Understandable: Readable text, predictable behavior, input assistance for error prevention
- Robust: Compatible with assistive technologies, valid markup
Accessibility is a Usability risk dimension — factor it into confidence scoring.
Persona and Context Integration
When they can change the current design decision, reference:
- Personas (
docs/product/personas/) — Who is using this? What's their context, skill level, environment? - Journey Maps (
docs/discovery/journeys/) — Where in their journey does this interaction happen?
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-perspective is a skill published in the GitHub repository shinpr/claude-code-discover (10 stars, last pushed 6d ago), licensed MIT. It adds 49 tokens to every session and 731 once invoked, about $0.0002 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.
