[Copilot Dreams] Prevent outdated setup and tool-migration advice

@@ -15,7 +15,7 @@ When generating the migration guide, consider the following aspects:
 
 * The initial tool file and its corresponding test file will have the `//go:build ignore` build tag, as the tests will fail if the code is not ignored. The `ignore` build tag should be removed before work begins.
 * The import for `github.com/mark3labs/mcp-go/mcp` should be changed to `github.com/modelcontextprotocol/go-sdk/mcp`
-* The return type for the tool constructor function should be updated from `mcp.Tool, server.ToolHandlerFunc` to `(mcp.Tool, mcp.ToolHandlerFor[map[string]any, any])`.
+* The return type for the tool constructor function should be updated from `mcp.Tool, server.ToolHandlerFunc` to `inventory.ServerTool`.
 * The tool handler function signature should be updated to use generics, changing from `func(ctx context.Context, mcp.CallToolRequest) (*mcp.CallToolResult, error)` to `func(context.Context, *mcp.CallToolRequest, map[string]any) (*mcp.CallToolResult, any, error)`.
 * The `RequiredParam`, `RequiredInt`, `RequiredBigInt`, `OptionalParamOK`, `OptionalParam`, `OptionalIntParam`, `OptionalIntParamWithDefault`, `OptionalBoolParamWithDefault`, `OptionalStringArrayParam`, `OptionalBigIntArrayParam` and `OptionalCursorPaginationParams` functions should be changed to use the tool arguments that are now passed as a map in the tool handler function, rather than extracting them from the `mcp.CallToolRequest`.
 * `mcp.NewToolResultText`, `mcp.NewToolResultError`, `mcp.NewToolResultErrorFromErr` and `mcp.NewToolResultResource` no longer available in `modelcontextprotocol/go-sdk`. There are a few helper functions available in `pkg/utils/result.go` that can be used to replace these, in the `utils` package.

 After migrating the tool code and test file, ensure that all tests pass successfully. If any tests fail, review the error messages and adjust the migrated code as necessary to resolve any issues. If you encounter any challenges or need further assistance during the migration process, please let me know.

 **Key Details:**
 - **Language:** Go 1.27.3+ (~38k lines of code)
 - **Type:** MCP server application with CLI interface
-- **Primary Package:** github-mcp-server (stdio MCP server - **this is the main focus**)
 - **Secondary Package:** mcpcurl (testing utility - don't break it, but not the priority)
 - **Framework:** Uses modelcontextprotocol/go-sdk for MCP protocol, google/go-github for GitHub API

 - **Library Usage:** This repository is also used as a library by the remote server. Functions that could be called by other repositories should be exported (capitalized), even if not required internally. Preserve existing export patterns.
 
 **Code Quality Standards:**
 - **Popular Open Source Repository** - High bar for code quality and clarity
-- **Comprehension First** - Code must be clear to a wide audience
 - **Clean Commits** - Atomic, focused changes with clear messages
 - **Structure** - Always maintain or improve, never degrade
 - **Code over Comments** - Prefer self-documenting code; comment only when necessary

-- Tests are in `*_test.go` files alongside implementation (internal tests, not `_test` package)
-- Mock GitHub API with `go-github-mock` (REST) or `githubv4mock` (GraphQL)
