pwa-expert

pwa-expert is a plugin for Claude Code from acaprino/daodan. Its manifest loads nothing; the 1 skill, 3 commands, 1 agent it bundles cost 425 tokens per session together, scanned A, original, MIT.

A set of guidance and commands for building Progressive Web Apps, or websites that can be installed and used like apps. It covers app manifests, service workers, push messages, installation, storage, security, performance checks, and store distribution.

In plain words
What is it for?
Use it to audit a local project or live URL, scaffold PWA files for supported web frameworks, and check whether a PWA is ready to deploy.
Why use it?
It brings the many browser, operating-system, and store requirements for a PWA into one development workflow. It can also check an existing app, create starting files, and walk through a production checklist.

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.

Security

Grade A, and why

pwa-expert 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 4d 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.

What it installs

The manifest is a name and a version. 1 skill, 3 commands, 1 agent travel with it, and installing the plugin installs all of them — 425 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
