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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00256 |
| Opus 5.5 | $0.00008 | $0.00102 |
| Sonnet 5.5 | $0.00004 | $0.00051 |
| Haiku 4.5 | $0.00002 | $0.00026 |
Grade A, and why
developer-platform-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 1mo 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
Developer Platform Design
Developer Experience Principles
- Time to first API call < 5 minutes. If it takes longer, your onboarding is broken.
- Show, don't describe. Code examples beat paragraphs.
- Copy-paste ready. Every code example should work when pasted.
- Error messages are documentation. Include fix suggestions in error output.
- Don't require signup to explore. Show docs publicly.
Documentation
- Quick start guide on the homepage.
- Interactive API explorer (try-it-now).
- Code examples in multiple languages.
- Changelog with clear breaking change indicators.
- Status page linked from docs.
CLI Design
- --help that's actually helpful.
- Colored output for readability.
- Progress indicators for long operations.
- Confirmation prompts for destructive operations.
- JSON output option for scripting.
Dashboard
- API key management (create, revoke, rotate).
- Usage metrics and quota.
- Logs and error tracking.
- Webhook management and testing.
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.

developer-platform-design is a skill published in the GitHub repository Dragoon0x/everything-design-taste (13 stars, last pushed 6mo ago), licensed MIT. It adds 19 tokens to every session and 256 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 2026-09-03.
