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 | $0.00103 | $0.02302 |
| Opus 5 | $0.00051 | $0.01151 |
| Sonnet 5 | $0.00021 | $0.00460 |
| Haiku 4.5 | $0.00010 | $0.00230 |
Grade A, and why
solid-core-overview 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.

Quick Reference
Version Matrix
| Package | Version | Status | Notes |
|---|---|---|---|
solid-js |
1.x (1.8+) | Stable | Fine-grained reactivity, signals, stores, effects, SSR, streaming |
solid-js |
2.0 | Beta | Microtask batching, async first-class, onSettled replaces onMount |
@solidjs/start |
0.x | Deprecated | Used createServerData$, createServerAction$ — NEVER use for new projects |
@solidjs/start |
1.0 | Stable | Uses "use server" directive, built on Vinxi/Vite/Nitro |
@solidjs/router |
< 0.15 | Legacy | Used cache function (now deprecated) |
@solidjs/router |
0.15+ | Stable | Introduced query (replaces cache), current API |
Key Version Dependencies
| Dependency | Requirement |
|---|---|
| SolidStart 1.0 | Requires @solidjs/router 0.15+ |
@solidjs/router |
Requires solid-js 1.8.4+ |
createAsync |
Bridge API between 1.x and 2.0 — use it NOW |
babel-preset-solid |
Required build dependency for JSX compilation |
Critical Warnings
NEVER use SolidStart 0.x APIs (createServerData$, createServerAction$) in new projects — they are removed in SolidStart 1.0. ALWAYS use "use server" with query/action instead.
NEVER use cache from @solidjs/router — it is deprecated. ALWAYS use query (available in router 0.15+).
NEVER import store utilities from solid-js — stores live in solid-js/store. Wrong imports cause runtime errors with no compile-time warning.
NEVER import rendering utilities from solid-js — SSR/hydration functions live in solid-js/web.
NEVER confuse @solidjs/router (current) with the old solid-app-router package — the old package is abandoned.
API Categories at a Glance
Reactivity Primitives (solid-js)
| API | Purpose |
|---|---|
createSignal |
Reactive value with getter/setter |
createEffect |
Side effects that auto-track dependencies |
createMemo |
Cached derived values (reactive source) |
createResource |
Async data fetching with loading/error states |
createComputed |
Synchronous pre-render state sync |
createRenderEffect |
Synchronous render-phase effects |
What ships with it
3 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.

solid-core-overview is a skill published in the GitHub repository OpenAEC-Foundation/OpenAEC-Workspace-Composer (5 stars, last pushed 5mo ago), licensed MIT. It adds 103 tokens to every session and 2,302 once invoked, about $0.0005 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.
