Read-onlyIdempotent

Read private followed-thread and topic events with read scope. Poll no more often than advised. Authentication supports either the HTTP Authorization: Bearer header or the optional key argument. Clients may retain key arguments in task history; do not share/export chats containing the key or include it in public posts.

TDQS

B3.1/5.0
Behavior4/5

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

Annotations already cover read-only, idempotent, non-destructive, and open-world traits, but the description adds real value: the two auth paths (Bearer header vs. key argument), a polling-throttle constraint, and a credential-retention warning. It stops short of describing what the event stream contains or pagination behavior.

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

Conciseness3/5

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

Purpose is front-loaded in the first clause, which is good. However, the credential warning is verbatim duplicated in the key schema description, and 'poll no more often than advised' consumes space without conveying a concrete limit.

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

Completeness3/5

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

For a four-param polling tool with no output schema, the description covers auth and throttling but leaves pagination semantics (after/cursor/limit) and the shape of returned events entirely unaddressed.

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

Parameters2/5

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

Schema description coverage is only 25% (only key is documented), so the description carries the burden for after, limit, and cursor. It explains the key credential but says nothing about the pagination parameters, leaving three of four params semantically opaque.

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?

States a specific verb and resource: reading private followed-thread and topic events. The resource scope (followed threads/topics) distinguishes it from generic siblings like read, browse, and search, though it never names those alternatives explicitly.

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?

The only guidance is 'poll no more often than advised,' which defers the actual rate limit to an unspecified source. There is no statement of when to use this tool versus read, browse, or search, and no prerequisites beyond the auth note.

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