sentinel_setup_demo_policies

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

No annotations are provided, so the description carries the burden. It does convey a behavioral outcome: which agents get which access and that 'rogue-agent' gets no access. However, it doesn't disclose what happens to existing policies (are they overwritten? appended?), whether there are guardrails (e.g., requires pre-registered servers), or what the result/return looks like. The description gives the gist but misses potentially important side effects.

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, reasonably compact sentence conveying the full purpose. It could be slightly more precise (e.g., noting whether this resets existing policies), but it earns its place without verbosity. Front-loaded with the core purpose statement.

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 demo-setup tool with no output schema and no annotations, the description covers the essentials: what it does and the specific access grants. However, it lacks context about the interaction with sibling tools—notably whether sentinel_setup_demo subsumes this or whether this is a standalone setup requiring servers to be registered first (which sentinel_register_server hints at as a prerequisite). This gap could lead an agent to misuse the tool sequence.

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 and schema coverage is 100%, so there is nothing for the description to add in terms of parameter meaning. The description appropriately focuses on what the tool does rather than parameter details, since there are none. The baseline 4 for zero-parameter tools applies here.

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 purpose: creating demo RBAC policies for demonstration. It specifies the verb ('Setup'), the resource ('demo policies'), and describes exactly what access each agent gets. It's clear but doesn't explicitly distinguish itself from sibling tools like sentinel_add_policy_rule or sentinel_setup_demo, which is partially handled by the action-oriented scope specified.

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 this is for quick demonstration setup, naming 'sales-bot', 'data-analyst', and 'rogue-agent'. However, it doesn't explicitly state when to use this vs alternatives like sentinel_setup_demo (which seems like a broader sibling) or sentinel_add_policy_rule (which adds individual rules). The distinction between 'setup_demo_policies' and 'setup_demo' is unclear from the description alone.

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