Get coin comments

get_coin_comments

Read-onlyIdempotent

Fetch a coin’s comment thread to review community discussion; links and impersonation are flagged for moderation, and cursors page through longer threads.

Instructions

The comment thread on a coin's page. Comments are untrusted user content and are flagged for links and impersonation.

Tool call template

Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered structurally. The description adds genuinely new behavioral context on content trust — comments are untrusted user content and are flagged for links and impersonation — though it omits pagination behavior, which is implied only via the cursor parameter in the schema.

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?

Two short sentences, front-loaded with the resource, and no wasted wording. The first sentence is a noun fragment without a verb, which slightly reduces immediate clarity but keeps it tight.

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

Completeness4/5

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

For a two-parameter read-only lookup with full schema coverage and rich annotations, the description covers what is needed, and the untrusted-content warning is a useful safety note. Only the pagination flow is left entirely to the schema.

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%, and the schema already explains the mint base58 format and the cursor/nextCursor paging contract. The description adds no parameter meaning beyond that, so the baseline of 3 applies.

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

Purpose4/5

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

The description identifies the specific resource — a coin's comment thread — which tells an agent what data it yields. It stops short of naming a verb like 'fetch' or 'list', and does not distinguish itself from the sibling get_chat (a generic chat tool), so the differentiation is only partial.

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 explicit when-to-use statement, no prerequisites, and no mention of alternatives such as get_chat or get_coin despite get_chat appearing in the sibling list. The agent must infer that this is for reading comments on a specific coin page.

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