get_repl_info

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

No annotations are provided, so the description must disclose behavioral traits. It only states 'get information' without describing side effects, authentication needs, or what the returned string contains. The return type 'str' is minimally informative.

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?

Description is short and uses a clear Args/Returns structure, making it easy to parse. It is efficient but could be slightly more concise by removing the docstring format if not needed.

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?

Given no output schema and many sibling tools, the description is too vague. It does not explain what 'information' entails (e.g., status, metadata, configuration), leaving the agent guessing about the tool's output and suitability.

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 coverage is 0%, so the description must compensate. It only restates the parameter name ('ID of the REPL to get info for') without adding format, constraints, or examples. This adds little value beyond 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 states the tool gets information about a specific REPL instance, using a specific verb and resource. It distinguishes from siblings like list_active_repls or get_repl_cwd by targeting a single repl_id, but does not specify what 'information' includes.

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?

No guidance on when to use this tool vs alternatives. Siblings include get_repl_cwd and list_active_repls, but the description does not clarify when get_repl_info is appropriate or what tradeoffs exist.

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