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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so safety is covered. The description adds real value beyond them by scoping the response to a single field of TitlePublicConfigurationModel and by explaining the semantics of the returned data (flows, step completion, scripted outcomes, gating). It says nothing about auth or rate limits, but for a read tool that is minor.

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 operative sentence is front-loaded, which is good, but the bulk of the description is an encyclopedia of the tutorial domain model (TriggerSource, TutorialScriptedOutcome, SegmentGate, ScheduleSpec, A/B testing). Much of it is tangential to invoking this tool, making the entry dense and over-long relative to the one-parameter operation.

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?

There is no output schema, so explaining what the Tutorial field contains is genuinely necessary, and the description does this well: it covers flows, step completion triggers, scripted outcomes, audience gates, schedules, and module gating. An agent can interpret results, though the returned object shape itself is only described conceptually.

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 description coverage is 100%, and the single required parameter title_id is documented in the schema itself. The description never mentions title_id or adds format/ID conventions, so it provides no meaning beyond the schema. Baseline 3 applies when the schema does the heavy lifting.

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?

Opens with a specific verb+resource+scope: 'GET ONLY the "Tutorial" field of TitlePublicConfigurationModel.' An agent immediately knows this is a read of one configuration slice. It does not explicitly name save_tutorial as the write counterpart, but the 'GET ONLY' phrasing plus the read-only annotation make the direction unambiguous.

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?

Usage is only implied: the tool reads tutorial definitions for a title. There is no explicit when-to-use, when-not, or named alternative (e.g. save_tutorial for edits, get_title_data for the full model). Instead the text spends its budget on domain semantics rather than routing the agent between siblings.

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