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 | $0.00079 | $0.01896 |
| Opus 5 | $0.00039 | $0.00948 |
| Sonnet 5 | $0.00016 | $0.00379 |
| Haiku 4.5 | $0.00008 | $0.00190 |
Grade A, and why
product-design-director 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 8d 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 — 215 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Product Design Director
Turn product intent into an implementable experience system. Direction comes from evidence and constraints, not a default aesthetic.
Trigger boundary
Use this skill for:
- establishing product, UX, brand, and visual direction for a new experience;
- redesigning an existing interface without losing functional truth;
- extracting a coherent design system from product/brand evidence;
- critiquing hierarchy, flows, states, responsive behavior, accessibility, and visual consistency;
- preparing an implementation-ready design brief for web or mobile builders.
Do not trigger for:
- reproducing a supplied screenshot or visual reference—use
screenshot-to-interface; - building an already-specified web/mobile interface—use the platform builder;
- choosing Flutter versus Expo—use
mobile-architecture-director; - applying a fashionable style without product, audience, and content evidence.
Required inputs
Gather or infer with labeled assumptions:
- product, user, job-to-be-done, and primary success action;
- content/information hierarchy and required flows;
- brand assets, existing product, competitors/references, and prohibited directions;
- target devices, input modes, languages, content variability, and accessibility obligations;
- technical/organizational constraints and delivery stage;
- for redesigns, screenshots and current implementation/state inventory.
Do not block on subjective adjectives alone. Translate “premium,” “simple,” or “bold” into observable hierarchy, density, typography, material, motion, and interaction choices.
Provenance
This skill is an original restructuring that selectively adapts concepts from Leonxlnx/taste-skill. Read references/provenance.md and preserve the root THIRD_PARTY_NOTICES.md when redistributing.
Safety baseline
- Inspect the current product, repository, and approved assets before proposing replacement.
- Preserve validated behavior, content obligations, platform conventions, and user work; do not disguise functional regression as visual simplification.
- Distinguish observed product/brand evidence from inference and subjective preference.
- Do not copy a competitor's protected assets, trade dress, or distinctive composition; record provenance and rights for supplied material.
- Do not use accessibility as a late polish step or trade it away for an aesthetic without an explicit product/legal decision.
- Do not prescribe a framework, package, or broad rewrite merely to express the direction.
What ships with it
5 files 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.

product-design-director is a skill published in the GitHub repository cmdr-chara/codex-toolkit (2 stars, last pushed 10d ago), licensed MIT. It adds 79 tokens to every session and 1,896 once invoked, about $0.0004 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.
