buildertrend_open

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

No annotations are supplied, so the description carries the full burden. It usefully discloses that the browser session is already signed in and that the default target is https://buildertrend.net, which speaks to auth state. It does not disclose whether navigation replaces the current page, whether it waits for load, what is returned, or what happens on an invalid URL.

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?

A single compact sentence covering purpose, default, and intent — front-loaded with the action. The phrase 'work with read job schedules and write daily logs' is slightly awkward but informative rather than wasteful.

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 one-optional-parameter navigation tool with no output schema and no annotations, the description covers what the tool does, the default target, and the signed-in session context. Gaps around post-navigation behavior and return value remain, but they are minor relative to this tool's simplicity.

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?

There is a single optional parameter with 100% schema description coverage, so the schema already documents 'Page to open. Default: https://buildertrend.net'. The description only restates the default URL, which does not add meaning beyond the schema; baseline 3 applies.

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 names a specific verb and resource — opening a Buildertrend page in a signed-in Cloud Browser — and adds a default domain plus the workflows it enables (reading job schedules, writing daily logs). It does not explicitly distinguish itself from siblings like buildertrend_read or buildertrend_click, so it falls short of a 5.

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?

Usage is implied rather than stated: 'to work with read job schedules and write daily logs' tells the agent this is the entry point that precedes in-page work. There is no explicit when-not guidance, no mention of what to do after opening, and no reference to alternatives such as buildertrend_read.

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