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 | $0.00104 | $0.02203 |
| Opus 5.5 | $0.00042 | $0.00881 |
| Sonnet 5.5 | $0.00021 | $0.00441 |
| Haiku 4.5 | $0.00010 | $0.00220 |
Grade A, and why
solid-errors-reactivity-debugging scanned grade A with 1 finding 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.

Quick Reference
Diagnostic Table: Symptom to Cause to Fix
| Symptom | Cause | Fix |
|---|---|---|
| UI never updates after signal change | Signal getter not called in JSX: {count} instead of {count()} |
ALWAYS call the getter: {count()} |
| Effect runs once, never again | Signal accessed outside tracking scope (component body, event handler) | Move signal access inside createEffect or JSX expression |
| Effect ignores some signals | Conditional access / early return before signal read | Read ALL signals before any conditional logic |
| Store property not updating in UI | Destructured store property: const { name } = store |
ALWAYS access via store.name in JSX |
| Store update has no effect | Direct mutation: store.name = "x" |
ALWAYS use setStore("name", "x") |
| Props stop updating | Destructured props: function Comp({ name }) |
ALWAYS use props.name, use splitProps if needed |
| Value is stale in timeout/callback | Signal value captured: const v = count() then used later |
Call count() at the point where you need the value |
| Effect works initially but stops | await inside effect breaks synchronous tracking |
Move async code to a separate function; read signals before await |
| Memo returns stale value | Memo dependency was untracked or destructured | Verify all signal getters are called inside memo callback |
| Store array update not reflected | Used store.items.push() instead of setter |
Use setStore("items", items.length, newItem) or produce |
Critical Warnings
NEVER destructure props in the function signature — this reads values once and permanently breaks tracking. ALWAYS accept props as a single object and access properties reactively.
NEVER store a signal getter result in a variable and expect it to stay current — const v = count() captures a snapshot. ALWAYS call the getter where you need the live value.
NEVER place await before signal reads in an effect — await breaks the synchronous tracking scope. ALWAYS read all tracked signals before any await.
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-reactivity-debugging is a skill published in the GitHub repository OpenAEC-Foundation/OpenAEC-Workspace-Composer (6 stars, last pushed 1mo ago), licensed MIT. It adds 104 tokens to every session and 2,203 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
