install_startup

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

Beyond annotations (destructiveHint, idempotentHint), the description adds critical behavior: default runs without elevation, launches via pythonw.exe with no terminal/focus change, and details the return JSON format. Also explains the UAC prompt requirement for run_as_admin.

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 concise, front-loaded with the main action, then details, then args/returns. Every sentence adds value, no filler.

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 description covers what the tool does, defaults, security implications (elevation, UAC), and return format. Missing are error cases or preconditions (e.g., user must be logged in), but overall it is fairly complete for the complexity level.

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 description only lists parameter names (run_as_admin, http, host, port) without adding value beyond the schema's detailed descriptions. Schema coverage from tool description is 0%, but the schema itself has good descriptions, so baseline is 3.

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 verb 'install' and resource 'scheduled task' with outcome 'starts automatically at user logon'. It distinguishes from sibling tools like uninstall_startup and startup_status by focusing on installation.

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 explains default behavior (no elevation, HTTP mode) but does not explicitly state when to use this tool versus alternatives like uninstall_startup or startup_status. No exclusions or prerequisites are mentioned.

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