Add check for SEP-986 (tool name format)

[nbarbettini]

Summary

SEP-986 and the current spec pin tool names to a specific format: 1–64 characters from [A-Za-z0-9_.\/-]. No existing scenario validates this: ToolsListScenario in src/scenarios/server/tools.ts only checks that name is truthy. Since tool name validity is inherent to every tools/list response, the natural home is an additional check on the existing ToolsListScenario.

Missing Coverage

Check: tools-name-format

Spec: Tool names are 1–64 characters long and match ^[A-Za-z0-9_.\/-]+$.

After tools/list, for each tool in result.tools, validate tool.name against the length bound and character class. Report FAILURE when any advertised tool name violates the format, with a per-tool breakdown in details. If result.tools is empty, report INFO (no tools to validate).

Proposed Location

Add as an additional check within the existing ServerToolsListScenario in src/scenarios/server/tools.ts, rather than a new standalone scenario.

The existing tools-list check already iterates result.tools.forEach(...) to validate presence of name/description/inputSchema, so the format validation slots in alongside the if (!tool.name) branch at tools.ts:48.

Spec Requirements (Tool Definition)

Keyword	Statement
MUST	Each tool's name is a non-empty string
MUST	Tool names MUST be 1–64 characters long
MUST	Tool names MUST match the regex ^[A-Za-z0-9_.\/-]+$ (letters, digits, underscore, hyphen, period, forward slash)
SHOULD	Tool names SHOULD be stable across server restarts for client-side caching
