Proposed fix: [Playwright MCP] browser_navigate to a local HTML file fails 'Access to "file:" protocol is blocked. Attempted URL: "file:///..."' — file:// navigation blocked by default

Proposed fix: [VS Code JS/TS] 'The path <p> doesn't point to a valid tsserver install. Falling back to bundled TypeScript version.' — typescript.tsdk / js/ts.tsdk.path points to a missing node_modules

Recommended action: Install dependencies (npm/pnpm install) so node_modules/typescript/lib exists, fix the path (e.g. ./node_modules/typescript/lib), then 'TypeScript: Select TypeScript Version' -> Use Workspace Version. With Yarn PnP, run the Yarn SDK setup so a tsserver path ex

Proposed fix: [Playwright MCP] 'Ref <ref> not found in the current page snapshot. Try capturing new snapshot.' — stale aria ref after navigation/DOM change

Recommended action: Take a fresh browser_snapshot and use the new ref (don't reuse refs across navigations/re-renders). Option: Take a fresh browser_snapshot and use the new ref (don't reuse refs across navigations/re-renders). [evidence: official_recommended_action] Applies when

Proposed fix: [GitHub Copilot CLI npm] 'GitHub Copilot CLI: no platform package found. Reinstall with `npm install -g @github/copilot`' — per-platform optional dependency missing

Recommended action: Reinstall globally on the target machine without omitting optional dependencies so npm fetches @github/copilot-<platform>-<arch>; on Alpine/musl ensure the linuxmusl package installs; on unsupported arches use another install method. Option: Reinstall globally

Proposed fix: [E2B SDK] 502 'The sandbox is running but port is not open' is reported with the generic suffix 'This error is likely due to sandbox timeout' — every 502 is formatted as a timeout, even

Recommended action: Read the message body: if it says the port is not open, verify the process in the sandbox is running and listening on that port (check logs via commands.run), and the template's start/ready command; only raise timeoutMs/.setTimeout when

Recommended action: Read in ranges with offset/limit, Grep for the target region, raise CLAUDE_CODE_FILE_READ_MAX_OUTPUT_TOKENS when full reads are needed, and avoid editing minified files directly (edit sources or use scripted edits). Option: Ranged reads and grep [evidence: off
