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 | $0.00143 | $0.03088 |
| Opus 5 | $0.00072 | $0.01544 |
| Sonnet 5 | $0.00029 | $0.00618 |
| Haiku 4.5 | $0.00014 | $0.00309 |
Grade A, and why
prototype-wp 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 4d 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 — 287 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Prototype a WordPress plugin
A prototype is throwaway code that answers a question. This one answers:
Does this specified plugin hold together as a product?
Not "does this logic feel right?" and not "what should this look like?" Those are different prototypes. A state machine with no WordPress surface wants a throwaway terminal app that re-renders the whole state after every keystroke. Visual variations on one component want several structurally different renderings of one route, switched from a floating bar. If the question is really one of those, say so and build that instead — this skill is the wrong shape for it.
This skill applies when there is a WordPress plugin, an admin or front-end surface, and an intent to evaluate behaviour before implementing it.
What this needs
| Static file server | One command, any runtime. kit/package.json aliases python3 -m http.server 4174; npx serve, php -S localhost:4174 and ruby -run -e httpd -- -p 4174 are equivalents |
| Browser driver | Anything that can evaluate JavaScript in the page and capture a screenshot — see VERIFY.md |
ffmpeg |
Optional, for the video recipes only; kit/RECIPES.md covers its absence |
No Node version, no dependency install, no build step. The prototype is classic scripts served as files.
Three layers
Every prototype is built as three separable layers. Keeping them separate is what makes two-thirds of the work copyable and the last third portable.
| Layer | Where it comes from | |
|---|---|---|
| Spine | WordPress-generic chrome — admin bar, menu, notices, list tables, metaboxes, capability and dependency gates | Copied from kit/KIT.md |
| Overlay | Host-plugin chrome — WooCommerce settings tabs, product editor, storefront | Copied from kit/, optional |
| Engine | The spec's own rules: resolution, precedence, validation, derivation. DOM-free | Written fresh, every time |

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.

prototype-wp is a skill published in the GitHub repository nathanonn/agent-skills (19 stars, last pushed 15d ago), licensed MIT. It adds 143 tokens to every session and 3,088 once invoked, about $0.0007 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.
