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 | $0.00113 | $0.02798 |
| Opus 5.5 | $0.00045 | $0.01119 |
| Sonnet 5.5 | $0.00023 | $0.00560 |
| Haiku 4.5 | $0.00011 | $0.00280 |
Grade A, and why
solid-errors-react-contamination 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 2mo 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.

Critical Warnings
NEVER destructure props in SolidJS components. Destructuring severs the reactive proxy connection. The component function runs ONCE — destructured values are frozen snapshots that NEVER update. This is the #1 source of broken SolidJS code generated by AI assistants trained on React.
NEVER assume components re-render. SolidJS component functions execute exactly ONCE to set up the reactive graph. Code in the component body that depends on state changes (derived values, conditionals, logging) MUST be wrapped in reactive primitives (createMemo, createEffect) or inline JSX expressions.
NEVER use dependency arrays. SolidJS tracks dependencies automatically. There is no [deps] argument to createEffect or createMemo. Adding one is a syntax error or passes it as the initial value parameter.
NEVER return cleanup functions from effects. SolidJS uses onCleanup() as a separate call inside the effect, NOT a return value.
NEVER use Array.map() for list rendering. It recreates ALL DOM nodes on every array change. ALWAYS use <For> or <Index> components.
Quick Reference — All Anti-Patterns
| ID | Pattern | Severity | Detection |
|---|---|---|---|
| AP-001 | Destructuring props | CRITICAL | function X({ prop } or const { x } = props |
| AP-002 | Destructuring signal value | CRITICAL | const val = signal() outside JSX/effect |
| AP-003 | useState instead of createSignal | CRITICAL | useState import or usage |
| AP-004 | useEffect instead of createEffect | CRITICAL | useEffect import or [deps] array |
| AP-005 | useMemo instead of createMemo | HIGH | useMemo import or dependency array |
| AP-006 | Re-render assumption | CRITICAL | Derived values as plain variables in component body |
| AP-007 | Conditional signal access | HIGH | Signal read inside if in effect |
| AP-008 | Early return before signal access | HIGH | return before signal call in effect |
| AP-009 | Storing signal in variable | HIGH | const x = signal() in component body |
| AP-010 | Spreading props unsafely | MEDIUM | {...props} without splitProps |
| AP-011 | Array.map for lists | HIGH | .map() in JSX return |
| AP-012 | Ternary instead of Show | MEDIUM | {cond ? <A/> : <B/>} |
| AP-013 | switch/case in component body | HIGH | switch statement in component return |
| AP-014 | key prop on list items | LOW | key={...} prop in For callback |
| AP-015 | useRef instead of let ref | MEDIUM | useRef import or .current access |
| AP-016 | React.createElement assumption | LOW | Manual element creation calls |
| AP-017 | children as static value | HIGH | props.children without children() helper |
| AP-018 | useEffect cleanup return | CRITICAL | return () => cleanup in effect |
| AP-019 | useRouter / next/router | HIGH | useRouter import |
| AP-020 | useEffect for data fetching | HIGH | fetch inside useEffect/createEffect |
| AP-021 | element prop on Route | HIGH | element={<Component/>} on Route |
| AP-022 | getServerSideProps pattern | HIGH | Separate data-fetching exports |
| AP-023 | Form onSubmit with preventDefault | MEDIUM | e.preventDefault() in form handler |
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-errors-react-contamination is a skill published in the GitHub repository OpenAEC-Foundation/OpenAEC-Workspace-Composer (6 stars, last pushed 1mo ago), licensed MIT. It adds 113 tokens to every session and 2,798 once invoked, about $0.0005 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 2026-08-31.
