pulse

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

With no annotations, the description carries the behavioral burden. It implies a read-only snapshot via 'high-water marks,' but it does not explicitly state that the tool is non-mutating, whether authentication is required, or what freshness guarantees exist. This is acceptable for a zero-parameter status tool but not fully transparent.

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 front-loaded sentence with no filler. It leads with the core concept, 'High-water marks,' and immediately lists the exact fields returned.

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 tool this is nearly adequate, but with no output schema the description only names fields without explaining their types or semantics. It also omits any context about when an agent would want this pulse data, leaving the tool somewhat under-specified.

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?

There are no parameters, so the schema leaves nothing to explain. The description appropriately focuses on the returned fields instead of parameters, matching the zero-parameter baseline.

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 identifies a distinct resource: a pulse/status summary with three concrete fields (last task id, last event id, member count). This differentiates it from sibling tools like list_tasks or get_member, though it uses a noun phrase rather than an explicit verb like 'returns'.

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?

No guidance is provided on when to use this tool versus alternatives. It does not mention status checking, monitoring, polling, or any condition that would select this tool over siblings, so the agent must infer usage entirely.

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