TDQS

B3.1/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is fully covered without the description. The description does add one piece of behavioral value beyond annotations — that replies are included in the response — but says nothing about depth/pagination of those replies or how the open-world lookup behaves when the comment is missing.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single short clause with zero filler, and the returned payload is front-loaded. It is efficient but sits at the edge of under-specification rather than being genuinely well-structured prose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema, so the description carries the return-value burden and does so by naming the three things the caller gets back: parent id, media id and replies. Combined with annotations that fully cover safety and idempotency and a schema that fully documents both parameters, nothing essential for a correct call is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with the account parameter documented (alias defaults to the configured default account) and comment_id constrained by a pattern, so the baseline of 3 applies. The description adds no meaning beyond the schema — it does not mention the account parameter, the id format, or what happens with an invalid or deleted comment_id.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description identifies a single-resource retrieval and names the returned fields (parent id, media id, replies), so the resource is clear. However, it is a verbless fragment that never states the operation explicitly ("retrieve"/"fetch"), and it does not name instagram_list_comments as the alternative, so differentiation from that sibling rests entirely on the name.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no when-to-use guidance at all: nothing says this is the follow-up to instagram_list_comments when you already hold a comment_id, and nothing states prerequisites or when to prefer the list tool. The only usage signal is the implicit get-vs-list naming convention.

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