begin_recording_login

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

The description adds meaningful behavioral detail beyond the annotations: it discloses that a browser is opened for sign-in, the user must complete password/MFA, and that the recording login is encrypted and bound to a verified Brightspace account. These traits are not derivable from annotations like openWorldHint=true and readOnlyHint=false.

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?

At roughly 50 words, the description is concise and front-loaded. The purpose sentence is the first sentence, followed by necessary flow instructions and a binding note. The final sentence adds a security nuance, though it is slightly loosely worded.

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 tool has no output schema and the description does not state what the call returns (e.g., an interaction token or a session identifier), which an agent may need. It does, however, provide enough high-level flow context—open chat, complete MFA, poll the status tool—to make the intended sequence understandable.

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%, so the baseline is 3. The description adds 'exact recording topic' and 'your own course' constraints, which help the agent avoid arbitrary input, but it does not add meaning about parameter formats or how to obtain either identifier beyond what the schema already says ('Exact Brightspace numeric identifier from another tool').

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 verb and resource: 'Open normal Collegerama/TU Delft sign-in for an exact recording topic discovered in your own course.' It is clearly scoped to recording login as opposed to mail or MyTU, though it does not explicitly name a sibling alternative.

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 a clear usage context ('for an exact recording topic discovered in your own course') and a follow-up step ('poll get_recording_login_status'), but it does not compare against sibling start-login tools such as begin_login, begin_mytu_login, or begin_mail_login. The when-not-to-use cases are left to inference.

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