SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? CTF sandbox challenges often hide the decisive bug in server-side rendering pipelines rather than in plain JSON APIs, and this Skill provides a structured method to trace route resolution, render context, and hydration handoffs to find it. ## Core Features & Use Cases - Render Chain Mapping: Records route matches, loaders, templates, layouts, hydration blobs, and client boot chunks for the active view. - Enforcement Boundary Comparison: Contrasts template-level gating, loader-level gating, and backend handler enforcement to expose mismatches. - Decisive Path Reduction: Compresses findings into the smallest request-to-render sequence proving the decisive branch. - Use Case: During a CTF web challenge, you suspect a hidden preview route leaks data through hydration JSON. Use this Skill to map the render chain, compare gating layers, and preserve a minimal success/failure request pair as evidence. ## Quick Start Ask the agent to map the SSR render chain for the target route and compare template gating with handler enforcement after the ctf-sandbox-orchestrator has established sandbox assumptions.

Frequently Asked Questions about competition-template-render-path

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I trace SSR template rendering bugs in a CTF challenge?▼

Map the render chain in order: route resolution, loader or data fetch, template context, response HTML, hydration payload, and client takeover. Then compare template-level gating against loader and handler enforcement to find mismatches.

What is hydration payload analysis in web security testing?▼

Hydration payload analysis inspects the JSON or inline data blobs embedded in SSR HTML that the client uses to take over rendering. Hidden fields, server-only variables, or leaked data often appear in these payloads even when the visible UI gates them.

When should I use this skill instead of a general web exploitation skill?▼

Use it only after the ctf-sandbox-orchestrator has established sandbox assumptions and routed here, and only when the decisive bug lives in route resolution, render context, or hydration handoff rather than a plain JSON API.

Why do template gating checks fail to prevent unauthorized access?▼

Template gating only hides content in the rendered UI while loaders or backend handlers may still return the underlying data. Comparing all three enforcement layers reveals where the actual authorization check is missing.

What evidence should I preserve when reporting an SSR render bug?▼

Keep route names, loader names, templates, hydration keys, and host or preview switches, plus one success/failure request pair showing where render-layer behavior diverges and one minimal request-to-render sequence reaching the decisive branch.
