TDQS

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The readOnlyHint annotation already covers the safety profile, and with zero parameters there is little behavior left to disclose. The description adds only that the value comes from the *running* process, which is mild extra context; it says nothing about return shape or whether the call depends on live server connectivity.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence with no filler. Every word earns its place, and the key disambiguation (MCP server vs Phabricator) is placed inside that sentence.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter diagnostic tool with no output schema, the definition is essentially complete. A brief note about what the returned version string represents (e.g., server package version, not Phabricator API version) would close the last gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes no parameters, so per the baseline this scores 4. The schema is empty and the description does not need to explain any arguments.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (Get) and a precise resource (the version of the running phabricator-mcp server), and crucially names the MCP server rather than the Phabricator instance, which no sibling tool reports on. An agent can tell instantly that this is a server-diagnostic call, distinct from the ~60 Phabricator API wrappers.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is only implied: an agent can infer this is a health/identity check to run before or when diagnosing connectivity issues. There is no explicit statement of when to call it (e.g., at startup, on connection failure) and no exclusions or alternatives named.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
