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

No annotations are provided, so the description carries the full burden of behavioral disclosure. The description discloses what data will be returned (mode, ids, URLs, counts), which is helpful, but doesn't state whether this is a read-only operation, whether any side effects occur, or what happens if no workspace is active. Since the description names the returned data types, it adds some transparency, but for a status tool the read-only nature is implied rather than explicit.

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

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

The description is a single, compact sentence that enumerates the exact output content (mode, ids, URLs, road/step counts). Zero waste, front-loaded with the verb, and every word earns its place. Ideal length for a no-parameter status tool.

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

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

The tool is a simple status read with 0 parameters and no output schema, so complexity is low. The description names the output categories which is reasonably complete. However, without an output schema or annotations, and without describing the return format/structure, there is some gap in knowing exactly what shape the response takes. Adequate but could detail the return structure or edge cases (e.g., no active workspace).

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

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

The tool has 0 parameters, which gives a baseline of 4. With no parameters, there is nothing for the schema or description to document in terms of parameter semantics, so this dimension is largely moot and the baseline applies.

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

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

The description clearly states what the tool does: returns 'mode, ids, URLs, and road/step counts' for the current MCP session workspace. It uses a specific verb ('Return') and resource ('current MCP session workspace'). However, it doesn't explicitly distinguish itself from sibling tools like roadflow_get, though the status/read-only intent is discernible.

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

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

The description conveys that this is a status/read-only tool for the current session workspace, which implies it should be used for inspection rather than modification. However, it provides no explicit when-to-use versus alternatives guidance, no exclusions, and doesn't mention when it would be preferable over roadflow_get or sibling read tools.

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