sentinel_setup_demo

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

No annotations are provided, so the description carries some burden. It states the tool registers 3 servers with the gateway, which implies state mutation. However, it does not disclose what happens if servers already exist, whether this overwrites existing registrations, or whether it affects policy rules or other persisted state. The sibling sentinel_setup_demo_policies and sentinel_reset_demo suggest relationship to broader demo state that isn't disclosed here.

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?

Two sentences, both substantive. The first delivers the core function, the second contextualizes usage. No filler or redundancy. Could arguably drop the trailing clause, but it's brief enough that it doesn't hurt.

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 is simple (0 params, no output schema) but has clear interactions with sibling tools like sentinel_setup_demo_policies, sentinel_run_full_demo, and sentinel_reset_demo. The description doesn't clarify ordering relationships or whether this tool should be run before/after those. For a setup/demo tool, understanding the sequence matters for correct usage.

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 0 parameters, so there's nothing for the description to document about parameters. The description correctly reflects that no inputs are needed — it's a self-contained one-step operation. This is a baseline for a zero-parameter tool and the description handles it appropriately.

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?

Description clearly states a specific verb+resource: registers 3 demo mock servers (filesystem, CRM, email) with the gateway in one step. It distinguishes itself as a batch/demo-setup operation versus the sibling sentinel_register_server which presumably does single registration. Slightly generic 'useful for demo initialization' but the specifics (3 named servers) make the purpose clear.

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 explicitly frames this as a 'Quick setup' for 'demo initialization', signaling it's for demo scenarios rather than production use. It implies this is an alternative to registering servers individually via sentinel_register_server. No explicit when-not guidance, but the demo context is clearly communicated.

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