// TestAllToolRegistrationsExplicitlySetReadOnlyHint statically scans every
|
|
// non-test Go source file in this package and asserts that every mcp.Tool
|
|
// composite literal explicitly sets Annotations.ReadOnlyHint.
|
|
//
|
|
// The AST scan itself lives in pkg/toolvalidation so downstream packages
|
|
// (e.g. github/github-mcp-server-remote) can apply the same guardrail to
|
|
// their own tool registrations without duplicating the parser logic.
|
|
//
|
|
// This complements TestAllToolsHaveRequiredMetadata, which can only check
|
|
// that Annotations is non-nil at runtime: Go cannot distinguish an unset
|
|
// bool field from one explicitly set to false. Source-level validation
|
|
// closes that gap and prevents future tool registrations from silently
|
|
// defaulting ReadOnlyHint to false (which has caused downstream agents to
|
|
// prompt for human approval on read-intent tools).
