Bootstrap Session

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

Annotations indicate non-read-only and non-destructive behavior, and the description adds that it combines start_session, context snapshot, and next tasks. However, it doesn't disclose whether it creates a new session, has side effects beyond initialization, or requires an existing session. The description adds some value but lacks depth.

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 a single, focused sentence that is front-loaded with the main purpose. It has no filler and conveys the essential function efficiently.

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?

The tool has no output schema and is a composite of three operations, yet the description only provides a high-level summary. It doesn't clarify what the response contains, the order of operations, or prerequisites. This is adequate for a simple tool but leaves gaps for an agent.

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% for all 4 parameters, so baseline is 3. The description mentions 'next unblocked tasks' and 'context snapshot' but doesn't directly map to task_limit or metadata. It adds no new meaning beyond the schema, which already documents each parameter.

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 clearly states the tool's verb ('initialization'), resource ('session'), and scope ('combining start_session, context snapshot, and next unblocked tasks'). It explicitly names the three constituent tools, distinguishing this composite tool from its siblings.

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 implies the tool is a convenience for a single-turn bootstrap, combining three separate operations. It provides clear context for when to use it, but doesn't explicitly state when not to use alternatives (e.g., when only one component is needed).

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