stata_session

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

Annotations are absent, so the description must carry the full behavioral burden. It does explain what session_id represents and what it is associated with, but it does not disclose the side effects of destroy, what get returns, how set_recent changes behavior, or whether these operations are safe or destructive. A session-management tool with a destroy action needs clearer behavioral disclosure.

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 front-loads the tool's purpose and action list, then adds essential session-semantics context. There is no fluff or repetition of the schema. It could be slightly better structured by separating the action enumeration from the session_id semantics, but it remains appropriately sized.

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?

With no output schema and no annotations, the description should clarify return values and behavioral outcomes for each action. It adequately covers what session_id means and which actions need it, but it does not explain what list/get return, what destroy removes, or what set_recent actually switches. The tool is simple enough that this is a moderate gap, not a fatal one.

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?

Schema description coverage is 100%, so the baseline is 3. The description goes beyond the schema by explaining that session_id identifies the same reproduction task/GUI and is linked to entry/source/current do and log paths. It also clarifies that get/destroy/set_recent require session_id, which is not reflected as a conditional requirement in the schema.

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 identifies the resource (Stata MCP session) and enumerates the four supported operations: list, get, destroy, and set_recent. This maps directly to the action enum and distinguishes the tool from siblings focused on running or editing do-files. '管理' alone would be vague, but the explicit action list makes the purpose concrete.

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 provides no explicit guidance on when to use this tool versus alternatives, and it does not explain when one action should be preferred over another. The action enum and the session_id note imply some usage contexts, but the description never states conditions like 'use list to discover active sessions' or 'destroy removes the session and its associated state.'

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