kchat_get_thread_replies

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

No annotations are provided, so the description carries the whole burden and discloses almost nothing. It does not say whether replies are ordered, whether the parent message is included, whether there is pagination or a result cap, or what access is required to read a thread.

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?

A single front-loaded sentence with no filler. It is lean to the point of under-specification, but nothing in it is wasted or buried.

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 one-parameter read tool with no output schema, the core intent is conveyed, but the return shape and completeness of results ('all replies') are left unexplained and no annotations fill the gap. Adequate minimum, with real gaps for an agent deciding whether it needs pagination or ordering guarantees.

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% and the single thread_id is already documented as 'The parent message ID', so the description adds no meaning beyond the schema. Baseline 3 applies; it does not clarify that the UUID must be the parent rather than an individual reply's ID.

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?

States a specific verb and resource: retrieve all replies belonging to a kChat message thread. The word 'replies' cleanly separates it from the write-side sibling kchat_reply_to_thread, though the description never explicitly names that or any other sibling.

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?

There is no guidance on when to reach for this versus kchat_get_channel_history or kchat_get_user_profile, and no stated prerequisites. The agent must infer from the name alone that this is the read path for a thread once it already has a thread ID.

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