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

The description goes well beyond the annotations, which only say the operation is not read-only, not open-world, not idempotent, and not destructive. It discloses concrete behavioral consequences: the first import creates a namespace_token shown exactly once, losing it makes the namespace unrecoverable, the call costs $0.010, private imports are never searchable, and mismatched transcript/visibility pairs are refused. This is rich, honest behavioral disclosure.

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 long but every sentence earns its place: purpose, input format flexibility, privacy/searchability trade-offs, one-time token handling, and cost/payment. It is front-loaded with the core purpose and then builds outward into operational details. There is no filler or redundant restating of the schema.

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?

Given the tool's complexity, the description covers almost everything an agent needs: raw format handling, cue merging, visibility semantics, namespace token persistence, and payment. An output schema exists, so detailed return values do not need to be explained. The only notable gap is the inconsistency between the description's claim that visibility is required and the schema's optional default, which leaves room for agent misinterpretation.

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%, so the baseline is already solid. The description adds valuable cross-parameter semantics: transcript is paired with 'queryable', ciphertext with 'private', namespace_token is required for later calls, and credit_token is an alternative payment path. However, it creates some confusion by calling visibility a 'required decision that cannot be guessed' while the schema lists it as optional with a default of 'private'. This tension prevents a top score.

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 immediately states a specific action and resource: 'Store a transcript so it can be searched later.' It also explains that raw WebVTT/SRT inputs are accepted directly, which clearly distinguishes this ingestion tool from sibling tools like meetings_get, meetings_search, and meetings_summarize. It is not a tautology and meaningfully expands on the title.

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?

The description gives strong contextual guidance: it says when to use the tool (raw transcript from Zoom/Teams/Meet/notetaker), removes a common preprocessing burden, and even routes users without credit to credits_trial. However, it does not explicitly state when to prefer this tool over related siblings like vault_store or compress, so it stops short of full when-not/alternatives guidance.

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