Ling: Skill for Claude Code

.agents/skills/app-builder/SKILL.md

app-builder is a skill for Claude Code from MisonL/Ling. It costs 41 tokens per session (977 once invoked), scanned A, original, MIT.

An orchestrator for planning and coordinating the construction of applications. It identifies the project type, selects a technology stack and template, plans the structure, and coordinates specialized assistants.

In plain words
What is it for?
Detecting whether a project is a web app, API, mobile app, desktop app, extension, or another type; choosing a suitable stack; creating its initial structure; and coordinating feature-building work.
Why use it?
It gives new projects a consistent path from an initial request to a working structure. It also limits reading and decisions to the parts relevant to the requested application.

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

app-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.

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.

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.
