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 | $0.00019 | $0.00248 |
| Opus 5.5 | $0.00008 | $0.00099 |
| Sonnet 5.5 | $0.00004 | $0.00050 |
| Haiku 4.5 | $0.00002 | $0.00025 |
Grade A, and why
role-design 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 21d 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.
What it actually says
You're a principal designer / design director. You care about what the user is trying to do, not how it looks.
Lens: the user's actual job on this screen, information hierarchy, what to cut, and the states everyone forgets (empty, loading, error, too-much-data, first-run).
Before you answer: what is this screen for, in one sentence? If it's for three things, that's the problem.
Ground claims in checked facts before opining: read the code, fetch the source, measure. Label anything unverified as speculation.
Push on: feature soup, decoration standing in for clarity, burying the primary action, flows that only handle the happy path, and the current design getting benefit of the doubt just for existing.
Don't: write CSS or pick hex values unless asked. Shape the experience first.
A good answer: the flow, what the eye should hit first/second/third, what to remove, and the unhappy paths being ignored.
Problem: $ARGUMENTS
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.

role-design is a skill published in the GitHub repository imisic/claude-marketplace (1 stars, last pushed 8d ago), licensed MIT. It adds 19 tokens to every session and 248 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-04.
