What is solid-component-builder?

A guide for building SolidJS components, which are reusable interface parts made with the Solid JavaScript framework. It sets rules for reactivity, asynchronous data, accessibility, server rendering, and testing.

Creating or modifying SolidJS components, defining their props and state ownership, handling asynchronous data, supporting server rendering, and preparing validation checks.

It helps components behave predictably across loading, error, browser, server, and hydration states.

Token cost

What it costs to keep this loaded

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	$0.00037	$0.00605
Opus 5.5	$0.00015	$0.00242
Sonnet 5.5	$0.00007	$0.00121
Haiku 4.5	$0.00004	$0.00060

Security

Grade A, and why

solid-component-builder 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.

How it starts

The opening of the file, as written. The whole thing — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.

solid-component-builder

Trigger

Use this skill for new or modified SolidJS components where component contract, reactivity, async behavior, accessibility, and SSR/hydration safety must be explicit.

Required Inputs

Component goal and user-facing behavior.
Prop interface and expected defaults.
Data dependencies and async boundaries.
Rendering context (client-only, SSR, or mixed).
Acceptance constraints (performance, accessibility, test expectations).

Workflow

Define component contract before implementation: props, emitted callbacks, ownership of state, and external dependencies.
Choose primitives by rule: pure derivations use createMemo; side effects use createEffect; async data uses createResource; grouped updates use batch.
Select control-flow primitives explicitly (<Show>, <For>, <Switch>/<Match>) and document why each is used.
Declare loading, empty, error, and success rendering states when async data is present.
Add SSR/hydration checks for browser-only behavior and deterministic initial render.
Produce validation checklist and commands before returning final output.

Failure Modes

Missing prop or data contracts: stop and request exact missing input keys.
Ambiguous state ownership: default to local ownership and document escalation path.
Missing async states: fail output and add explicit loading/error/empty branches.
Hydration mismatch risk: require server/client render parity note before completion.

Output Contract

Return output matching ComponentBuildOutput schema at ../../skills/contracts/component-build-output.schema.json with:

summary, implementation_plan, and component_contract.
reactivity_decisions, acceptance_checklist, and validation_commands.
citations: each item must include doc_id and claim sourced from normalized references.

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-component-builder is a skill published in the GitHub repository lvcoi/solidJSkills (9 stars, last pushed 8mo ago), licensed MIT. It adds 37 tokens to every session and 605 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 2026-08-31.
