    Repair CORS, Origins & Browser Requests

    Example session with this skill installed

    Our API works in curl but fails in the browser after moving behind a reverse proxy. Credentialed requests from two allowed origins fail preflight or lose cookies, and redirects behave differently. Repair the browser request boundary without using wildcard origins.

    • Read your context and instructions
    • Compiled the repair cors origins

    The likely failure is a contract mismatch around CORS, preflight requests, origins, credentials, cookies, redirects, proxy headers, caching, browser request modes, and cross-origin policy boundaries. I would reconstruct one canonical invariant, identify the layer violating it, apply the smallest bounded repair, and add deterministic boundary/failure/control tests. Existing security and product policy would be preserved. If repository files are available I can map the repair to exact paths; otherwise I would provide concrete pseudocode and a verification plan without claiming execution.

    About this skill

    Repair CORS, Origins & Browser Requests is a bounded ToolForge Labs workflow. Diagnose and repair CORS, preflight requests, origins, credentials, cookies, redirects, proxy headers, caching, browser request modes, and cross-origin policy boundaries. Works from repositories or partial logs/configuration. Produces bounded repair patterns and deterministic tests while preserving existing product/security policy and avoiding invented execution claims. It works from a full repository or partial evidence such as snippets, logs, configuration, traces, tickets, and architecture notes. The skill preserves existing product and security policy, separates verified facts from assumptions, avoids invented execution claims, and produces concrete repair or review steps with focused deterministic validation or traceable evidence.
