peoplehub_login

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

With no annotations, the description carries the burden of behavioral disclosure. It reveals that Chromium will open, an SSO login will occur, and a session file will be saved at a specific filesystem path. This is sufficient transparency for a login tool.

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 concise sentences deliver the core purpose, the mechanism, the side effect, and the recommended usage cadence. There is no redundancy or unnecessary detail.

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?

The definition is complete enough for a simple login tool: it explains what happens, where the session is stored, and when to run it. It could slightly improve by noting that manual user interaction in the browser is expected, but this is reasonably implied by 'iniciar sesión' with SSO.

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 only parameter, timeout_seconds, is fully documented in the schema. The description adds no extra parameter-level detail, but given 100% schema coverage, the 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 states a specific action and resource: it launches Chromium to sign in to PeopleHub via Microsoft SSO and stores the session locally. This clearly distinguishes it from sibling tools that list data or log hours.

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 gives clear usage context: run once per user or when the session expires. It does not explicitly mention or exclude alternatives like peoplehub_session, so it falls just short of full routing guidance.

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