prewarm_transcript

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

With no annotations, the description carries full behavioral burden and largely fails it. It only vaguely gestures at return content ('initial_state + blob ids'), with no statement of whether the call is read-only, whether it mutates or warms server state (the name suggests PREWARM), what auth scope is needed, or how large/failure-prone the response is.

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?

The description is short but telegraphic fragments ('Extended: ...', 'Raw record behind the transcript viewer') rather than front-loaded explanation. Brevity here is under-specification, not economy; the reader gains no actionable framing from either fragment.

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 tool with no annotations, no output schema, and a single undocumented-in-prose parameter, the description should define what is returned and under what conditions it is called. It leaves the core question — what does an agent get back and when should it use this versus get_blob or get_conversation — entirely unanswered.

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?

High schema coverage (100%) sets a baseline of 3, but the description adds nothing about bcId — it does not clarify whether this is an agent ID, a blob container ID, or the same 'bc id' used elsewhere. The isolated mention of 'blob ids' muddies rather than clarifies the parameter's role.

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 description is telegraphic jargon: 'StreamConversation PREWARM initial_state + blob ids' names an internal artifact rather than a concrete verb+resource. An agent cannot confidently say whether this reads a cached prewarm record, warms a cache, or fetches transcript data, and nothing distinguishes it from siblings like get_blob or get_conversation.

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?

No when-to-use, prerequisites, or alternative is stated. The sibling set (get_blob, get_conversation, get_artifact_url) overlaps plausibly with this tool's territory, yet the description offers no routing guidance at all.

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