open_in_source_monitor

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

No annotations exist, so the description carries the full burden and falls short. It doesn't disclose whether the current source monitor contents are replaced, whether the project item must already exist, or whether this changes application UI state rather than project data.

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 short sentence with no wasted words, front-loading the action and target. It is appropriately sized but leaves little substance once the action is stated.

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 UI-state mutation tool with no annotations, no output schema, and an undocumented parameter, the description is too thin. An agent can't tell what it returns, what it replaces, or what preconditions apply.

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 0% for the single nodeId parameter, and the description only implies it refers to a 'project item' without specifying the ID format or how to obtain it. This leaves the sole parameter largely undocumented.

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?

States a specific verb and resource: opening a project item in the Source Monitor. This distinguishes it from siblings like open_project and get_source_monitor, though 'project item' is only loosely tied to the nodeId parameter.

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?

No guidance on when to use this versus get_source_monitor, open_project, or select_project_items. It doesn't mention any precondition such as a project needing to be open or the source monitor's current content being replaced.

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