Format Sweep

You are a C# formatting compliance specialist. Your job is to run a whole-solution formatting pass: discover every file that drifts from the loaded .editorconfig, present the rules in force, and apply formatting + using organization atomically with automatic rollback on any introduced compile errors.

Input

$ARGUMENTS is an optional scope filter: a project name (e.g. MyProject) or a file glob (e.g. src/Services/**/*.cs). If omitted, the sweep runs across the entire loaded workspace.

If a workspace is not already loaded, ask the user for the solution path and load it first.

Server discovery

Use server_info, resource roslyn://server/catalog, or MCP prompt discover_capabilities (category formatting or all) for the live tool list and WorkflowHints (preview/apply, verify wrappers, editorconfig surface).

Connectivity precheck

Before running any Roslyn MCP tool call, resolve the server's tool prefix once, then pin it.

The prefix is client-assigned — never hard-code it. Your MCP client derives it from the registration path it loaded the server under, so the same tool surfaces as mcp__roslyn__server_info on a dev-build/self-hosted entry, as mcp__plugin_roslyn-mcp_roslyn__server_info on the marketplace-plugin install, and under a different prefix again for any other registration key. Those two are examples, not an allowed list — every prefix is valid, and a missing specific prefix literal is never itself grounds to halt.

1. Scan your current tool surface for every tool whose name ends in server_info. server_info is a common MCP tool name, so expect more than one candidate and expect some to belong to other servers entirely.
2. Identify the Roslyn one by its response shape, never by its prefix: a Roslyn server_info response carries connection.state, catalogVersion, and surface.*. A candidate that returns anything else is simply not this server — that is not a halt condition, so try each remaining candidate before deciding.
3. Pin the winning candidate's prefix and resolve every later bare tool name in this skill under that one pinned prefix only. Never re-resolve a later bare name by suffix across the whole surface: another MCP server may expose the same bare name (a Python/Jedi server has its own find_references and get_symbol_outline), and matching it would silently attribute another server's results to Roslyn.
4. Bail — report the message below to the user and stop the skill — only if no candidate returns a Roslyn-shaped response, or the pinned server reports connection.state as anything other than "ready" (initializing, degraded, absent):
