ichilov_login

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

With no annotations, the description carries the full behavioral burden, and it does disclose two important traits: the credential handling happens off-chat, and it self-detects an already-signed-in state. Still missing are failure behavior, link validity/expiry, and whether it invalidates an existing session.

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?

Two dense sentences with the core action front-loaded and the security constraint kept to one parenthetical. Nothing is redundant, though the closing status clause adds a second, different behavior that could have been split or dropped.

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 zero-parameter tool with no annotations and no output schema, the description covers the essential mechanics and the critical security note. It stops short of explaining how the returned link is consumed, what the already-signed-in status looks like, or how it relates to the session-status sibling.

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 takes zero parameters, so there is nothing for the description to disambiguate; the baseline for a no-argument tool is 4.

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?

Names a specific verb and resource: it fetches the sign-in link for beWell. The trailing clause about returning status when already signed in correctly signals one branch of behavior, though it partially overlaps with the sibling ichilov_session_status, which weakens the differentiation slightly.

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 parenthetical makes the intended channel clear (credentials typed on the page, never in chat), which is real usage guidance. However, it never states when to call this versus ichilov_session_status or ichilov_logout, so the agent must infer the sequencing.

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