Sign in to AnswerHatch

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 it holds a bearer token for the session, never prints the password, and does not create accounts. Missing failure behavior, but the key stateful and safety behaviors are covered.

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 concise and front-loaded with the primary action. Each sentence adds distinct value: session token, usage prerequisite, skip condition, account creation boundary, and password privacy. No wasted words.

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?

For a login tool with no output schema, the description explains the session token and the skip condition, which are essential. It could mention what happens on failure or whether a return value exists, but these are not critical for a session initiator. Overall, it is complete enough for an agent to use correctly.

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 both email and password are already documented. The description adds a note about not printing the password, which is more behavioral than parameter-specific, so it provides minimal extra semantic 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?

Clearly states the verb 'Sign in' and the resource 'AnswerHatch', and explicitly says it holds the bearer token for the session. It differentiates from siblings by instructing to call it before any other answerhatch tool, making its role unambiguous.

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?

Provides explicit guidance: call once before other tools, skip if ANSWERHATCH_TOKEN is set, and it does not create accounts (directing to signup). This fully addresses when to use and when not to use, including alternatives.

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