duplicate_comment_trigger

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

Beyond the annotations (readOnlyHint=false, idempotentHint=false, destructiveHint=false), the description discloses the concrete side effects: the copy is named '(Copy)', starts paused, and gets fresh stats. It also reveals two non-obvious invocation requirements — an empty JSON object body and a Content-Type header — which an agent would otherwise get wrong.

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?

Three short sentences, each with a distinct job: what it does, what the result looks like, and the exact call mechanics. The most important facts (copy semantics, paused state) are front-loaded with 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?

With no output schema, the description should say what comes back — critically, the new trigger's id, which the agent needs to perform the suggested 'PATCH active: true' step. The invocation mechanics and side effects are well covered, but the return value and how to obtain the copy's id are left unstated.

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 coverage is 100% for the single 'id' parameter, so the schema already carries the meaning. The description adds nothing about which trigger id is expected (source vs. copy), leaving the schema to do all the work, which matches the baseline of 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 opening sentence names a specific verb and resource ('Duplicate a comment trigger') and immediately clarifies it produces a new trigger rather than modifying the existing one. This cleanly separates it from create_comment_trigger and update_comment_trigger in the sibling list.

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 makes the use case clear: copy an existing trigger instead of rebuilding one, and it explains the follow-up step ('Activate it with PATCH active: true'). It does not explicitly say when to prefer create_comment_trigger over this, but the context is strong enough for correct selection.

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