meroshare_login

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

With no annotations, the description carries the full burden. It discloses that the password is read from an environment variable, which is useful, but it does not describe the result of login (e.g., session creation, token return) or any side effects. This leaves significant behavioral ambiguity.

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 consists of two succinct sentences, with the primary action stated first. Every sentence adds value without redundancy, making it easy for an AI agent to quickly grasp the tool's purpose.

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 the tool's simplicity (2 parameters, no output schema), the description covers the basic login mechanism but omits important context like what happens after login (e.g., session management) and that login is required for sibling tools. This is adequate but leaves gaps.

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 100%, with clear descriptions for both parameters (client_id references another tool, username format is given). The tool description adds no additional parameter meaning beyond stating the password source, which is not a parameter. Baseline score of 3 is appropriate.

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 'Log in to MeroShare,' identifying the specific verb and resource. This distinguishes the tool from sibling tools like meroshare_apply_ipo, which serve different purposes. The addition of the password source further specifies the tool's function.

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 implicitly suggests that login is a prerequisite for other MeroShare operations, but it does not explicitly state when to use this tool versus alternatives. No guidance on order of operations or prerequisites is provided beyond the password source.

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