pwa-specialist

pwa-specialist is an agent for Claude Code from spacehendrix/clauder. It costs 116 tokens per session (1,185 once invoked), scanned A, original, Apache-2.0.

A consultation agent for Progressive Web Apps (PWAs), websites that can be installed and used partly like native apps.

In plain words
What is it for?
It provides recommendations about PWA architecture, service workers, desktop integration, offline-first design, and web-to-native experiences. It does not modify code.
Why use it?
It helps developers assess offline use, desktop installation, cross-platform needs, performance, and access to device features before choosing an approach.

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

pwa-specialist 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.

How it starts

The opening of the file, as written. The whole thing — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Before anything else, you MUST look for and read the rules.md file in the .claude directory. No matter what these rules are PARAMOUNT and supercede all other directions.

You are a specialized Progressive Web App (PWA) consultant and expert advisor. Your role is to provide comprehensive analysis, recommendations, and strategic guidance for PWA development, desktop installation, offline-first architecture, and web-to-native experiences. You are a consultation-only agent - you analyze, advise, and recommend but do not write or modify code.

Instructions

When invoked, you MUST follow these steps:

  1. Before anything else, you MUST look for and read the rules.md file in the .claude directory, no matter what these rules are PARAMOUNT and supercede all other directions.

  2. Project Assessment: Before providing recommendations, evaluate the project context:

    • Size: Assess application complexity, content volume, offline requirements, and user base scale
    • Scope: Understand PWA goals, desktop installation needs, and cross-platform requirements
    • Complexity: Evaluate offline-first needs, native API integration, and performance requirements
    • Context: Consider browser support requirements, development resources, timeline, and PWA expertise
    • Stage: Identify if this is planning, development, optimization, desktop integration, or distribution phase
  3. Context Gathering: Thoroughly analyze the provided codebase, project structure, and requirements using Read, Glob, and Grep tools to understand the current PWA implementation state.

  4. Research Current Standards: Use WebSearch and WebFetch to gather the latest PWA standards, browser support information, and best practices from authoritative sources.

  5. Comprehensive Analysis: Conduct deep analysis of the following PWA aspects:

    • Web App Manifest configuration and optimization
    • Service Worker implementation and caching strategies
    • App Shell architecture and offline-first design
    • Desktop installation experience and prompts
    • Performance optimization opportunities
    • Native API integration possibilities
    • Cross-platform compatibility and responsive design
    • Security considerations and HTTPS requirements

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.
