inspector_track_rebuild_dirty_widgets

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

No annotations are provided, so the description carries the full burden. It mentions the default port (8181) and that it connects to Flutter debug, but lacks critical behavioral details such as whether this is a read-only or mutating operation, potential side effects, performance impact, or how results are accessed. For a tool with no annotations, this is insufficient disclosure.

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?

The description is front-loaded with the core purpose in the first sentence, followed by connection details. It is concise with only two sentences, no redundant information, and efficiently conveys essential context without waste.

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?

Given no annotations and no output schema, the description provides basic purpose and connection info but lacks completeness for a debugging tool. It does not cover behavioral traits, output format, or error handling, leaving gaps that could hinder effective use by an AI agent.

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 description coverage is 100%, so the schema fully documents the parameters ('enabled' and 'port'). The description adds no additional semantic meaning beyond what the schema provides, such as explaining the implications of enabling/disabling tracking or port usage. Baseline 3 is appropriate when schema coverage is high.

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 clearly states the tool's purpose: 'Track widget rebuilds to identify performance issues.' It specifies the verb ('track'), resource ('widget rebuilds'), and goal ('identify performance issues'), but does not explicitly differentiate it from sibling tools like 'inspector_is_widget_creation_tracked' or 'inspector_get_children_details_subtree', which prevents a score of 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?

The description implies usage context by mentioning connection to the Flutter debug port, but it does not provide explicit guidance on when to use this tool versus alternatives (e.g., other inspector tools for debugging). There is no mention of prerequisites or exclusions, leaving the agent to infer usage from the purpose alone.

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