agents-heartbeat

agents-heartbeat

Refresh an agent session's heartbeat to keep the agent marked online. Call periodically to prevent the session from being swept offline.

Instructions

Refreshes an agent session's heartbeat. Bumps last_heartbeat_at to keep the agent marked online. Call periodically (~30s) to avoid being swept offline.

current_case_idNoOptional new current case if the agent switched focus
Behavior4/5

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

Discloses that the tool updates last_heartbeat_at (mutation) and mentions consequences of not calling it. No annotations provided, but the description covers key behavioral traits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences with no wasted words. All information is directly relevant and front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (2 params, no output schema), the description provides sufficient context for correct usage. Could potentially mention error scenarios, but not critical.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema has 100% coverage with descriptions for both parameters. The tool description adds no additional parameter semantics beyond what the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it 'refreshes an agent session's heartbeat' and explains the effect of bumping last_heartbeat_at to keep online. This distinguishes it from sibling tools like agents-register and agents-deregister.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly states to 'call periodically (~30s) to avoid being swept offline', providing clear usage guidance and interval.

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