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

Annotations already disclose readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds that examples are starting points, that the builder retains brand/customer/pricing/model ownership, and that the name keeps a legacy identifier. These are useful domain-context additions but not operational behavior like return format or limits.

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 series of loosely connected sentences that do not front-load the core action of listing examples. It includes philosophical framing ('An example is a starting point, never a finished product...') and a meta note about the legacy name, which dilute the message. A tool definition should lead with what it does and when to use it.

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 zero-parameter read-only listing tool with no output schema, the description partially covers what an example contains and adds ownership caveats, but it never explicitly states that the tool returns a list of launch kits or what the list structure looks like. It leaves the agent to infer the return type from the name and title.

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 tool has zero parameters, so there are no parameter semantics to explain. Per the rubric, a zero-parameter tool earns a baseline of 4. The description does not need to add parameter details.

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 opens by describing the content of an example ('Worked examples of what a kind of business uses...') rather than stating the tool's action of listing. The tool name and title carry the verb, but the description itself never explicitly says it returns a list. It does distinguish from trustycap_compose_kit by calling itself 'optional reading', which helps separate it from that sibling.

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?

It mentions trustycap_compose_kit and says a described business can be composed without one, and that for 'make this production ready' the backend install contract is the default. However, it does not say when to use this tool versus get_launch_kit, list_capabilities, or other siblings. The guidance is more a disclaimer than usable when-to-use instructions.

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