decompile-spa

Reverse-engineer a single-page application: unbundle its JavaScript, reconstruct the module graph, map its client-side routes, and detect its state-management framework.

This skill composes three underlying crawlio-agent-headless skills via the @crawlio/mcp aggregator. The aggregator dispatches the calls through the crawlio-agent-headless pillar, which provides the grep/interceptor/browser tiers required for static and dynamic analysis.

When to Use

• User wants to "understand how this app is built" without reading minified source by hand
• User asks to "find the routes" or "map the state management" of a live SPA
• Preparing for a design-system extraction or a competitive teardown — this skill produces the structural substrate that later skills depend on

Do NOT use this skill on sites you do not own or do not have authorization to analyze. Reverse engineering is scoped to legitimate research, competitive teardowns you are authorized to run, and your own applications.

Headless RE Session API

The headless pillar uses a session-based API. You do not call individual skills directly — you create a session, then run skills within it. The session tracks budget, artifacts, and gaps across skill invocations.
