install_startup

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

The description adds valuable behavioral context beyond the annotations: it runs without elevation, uses pythonw.exe in HTTP mode, and causes no terminal or focus change at logon. This complements the destructiveHint/idempotentHint annotations without contradicting them.

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 and well-structured: a one-sentence purpose, a one-sentence behavioral note, and a compact args/returns summary. Every sentence earns its place without unnecessary detail.

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 the essential aspects: task installation, logon trigger, elevation behavior, and HTTP mode. The output schema handles return structure, so the return description is not strictly necessary. It lacks an explicit note about Windows prerequisites, but the overall context is sufficient for a well-scoped tool.

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 and port options') without explaining their semantics. Since the schema description coverage is reported as 0%, the description does not compensate for the lack of parameter meaning, even though the nested schema itself contains descriptions.

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 opens with a clear, specific verb and resource: 'Install a scheduled task so this server starts automatically at user logon.' This directly states the tool's function and distinguishes it from related sibling tools like uninstall_startup and startup_status.

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?

It provides clear context for when to use the tool (automatic startup at logon) and explains the default execution mode (HTTP via pythonw.exe, no elevation). However, it does not explicitly mention alternatives or exclusions, such as checking startup_status first or using a different installation method.

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