trmnl_project_compare

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

The annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=true, and destructiveHint=false, so the safety profile is covered. The description adds that the comparison is between local files and an existing private plugin, but it does not describe the comparison output, authentication needs, or remote-fetch behavior.

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 a single, front-loaded sentence with no filler. Every word contributes to the stated purpose.

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 read-only compare tool with strong safety annotations, the description gives enough to understand its role before deployment. However, with no output schema and no parameter documentation, it should explain what the comparison returns and how the three identifiers are used.

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 0% for three parameters, so the description carries the full burden. It hints that 'local files' and an 'existing private plugin' are involved, but it does not explain what id, profile, or pluginSettingId mean or how they map to those concepts.

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 states a specific verb and resource: compare local files against an existing private plugin, and places it before deployment. This distinguishes it from siblings like trmnl_project_validate and trmnl_project_deploy, though it does not clarify what the comparison produces.

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 phrase 'before deployment' implies when to use the tool, giving useful context. However, it does not name alternatives such as trmnl_project_validate or explain when not to use this comparison.

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