webapp-builder

webapp-builder is a skill for Claude Code, Codex from sidequery/sidemantic. It costs 119 tokens per session (4,817 once invoked), scanned A, original, AGPL-3.0.

A guide for building interactive analytics web apps around Sidemantic semantic models. It uses reusable interface components and lets developers inspect the queries used to retrieve metrics.

In plain words
What is it for?
Use it when creating dashboards, demos, metric explorers, or embedded analytics interfaces based on Sidemantic models.
Why use it?
It provides a defined approach for turning existing analytics models into usable screens without hiding how the data queries work. The supplied description does not specify the exact app features or supported models.

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.

Security

Grade A, and why

webapp-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 1mo ago.

The scan reads SKILL.md. This mod also ships 8 executable files (assets/templates/static-dashboard/app.js, assets/ui-dist/sidemantic-ui-static.js, assets/ui-dist/sidemantic-ui.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.
