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

Annotations already declare readOnly, idempotent, openWorld=false and non-destructive, so the safety profile is covered. The description adds a genuine behavioral requirement beyond that: the agent must first ask the user's background before proceeding, and enumerates the valid background values. It stops short of describing the shape/tone of the generated path, but is solid for a read-only generator.

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?

Front-loaded with the core purpose, then routing rules, then the prerequisite interaction. Every sentence carries usable information, though the multi-clause final sentence about search/get_faq/get_api_reference is slightly dense.

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 single-parameter, read-only, non-open-world tool with no output schema, the description supplies purpose, routing, and the required pre-call interaction. The only minor gap is that it doesn't hint at what the generated guide looks like, but nothing essential to correct invocation is missing.

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% and the single 'background' parameter is a fully-enumerated string with its own description. The description reinforces the interaction ('Ask the user's background first') and lists the same six categories, adding workflow meaning but no new parameter semantics beyond the schema. Baseline 3 is appropriate.

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?

States a specific verb and resource ('Generate a personalized Canton Network developer onboarding/quickstart path') and immediately scopes it as Canton-only. An agent can distinguish it from siblings like get_faq, get_api_reference, and search without opening a schema.

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?

Explicitly states when to use (developer asking how to start/build a dApp on Canton), when not to use (other chains/tools), and names the alternatives that handle adjacent requests ('get_faq for a single specific gotcha', 'get_api_reference for API details', prefer over 'search'). This is textbook routing guidance.

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