indico_create_session

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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds useful behavioral context beyond annotations by revealing that the created session initially has no time slot and requires indico_create_session_block for scheduling. It does not contradict the annotations.

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 two short sentences, front-loaded with the core action and followed by a critical workflow detail. Every sentence earns its place with no redundancy or filler.

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 that an output schema exists and annotations cover safety, the description supplies the key scheduling dependency an agent needs to act correctly. It is complete enough for invocation, though it could still mention parameter expectations or permissions more explicitly.

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?

The description adds no information about any of the six parameters. With only 50% schema description coverage, the description does not compensate for undocumented parameters such as title, description, or default_contribution_minutes. It leaves parameter semantics entirely to the input schema.

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 states a specific verb and resource: 'Create a session.' It also distinguishes the initial state from a session block by noting the session has no time slot until indico_create_session_block is used. An agent can identify the tool's purpose and relationship to the sibling tool without inspecting schemas.

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 a clear workflow dependency: create a session first, then use indico_create_session_block to assign a time slot. This helps an agent understand the required sequence. However, it does not explicitly state when to use this tool versus update_session or other create tools, nor does it mention exclusions.

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