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

With no annotations, the description carries the burden of disclosing behavior. It explains the non-destructive flow: find a running IDE window, capture a screenshot, optionally scan the project directory. It does not cover failure behavior when no IDE is found, prerequisites, or permission requirements.

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-loads the purpose, then explains behavior, then gives parameter semantics in a clean Args section. There is minor redundancy between 'Delphi/Lazarus IDE' and 'RAD Studio, Delphi, or Lazarus,' but no material fluff.

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 tool with one optional parameter and no output schema, the description covers purpose, behavior, parameter semantics, and expected outputs adequately. Missing details about return structure and error cases like 'no IDE window not found' keep it from being fully complete.

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 schema only says project_dir is a string or null with zero description coverage, but the description adds real meaning: it is an optional path to the project directory and, if provided, the tool also returns a list of source files. It lacks path format guidance or examples, so not a 5.

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 action (observe/capture screenshot of the Delphi/Lazarus IDE) and describes the combined output of screenshot plus project info. It is clear what the tool does, though it does not explicitly contrast itself with sibling tools like screenshot_app, focus_ide, or read_ide_errors.

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?

Gives clear context for when to use it: the agent should call this when Claude needs to spot compiler errors, warnings, or messages in the IDE's Messages pane. It stops short of a 5 because it does not explicitly state when not to use it or name alternatives.

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