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

Annotations declare readOnlyHint=true and openWorldHint=false, so safety is covered; the description adds the key behavioral fact that the output is executable shell commands for the target box plus a cron entry. It also flags that the token came from create_monitor, a one-time reveal. It does not say whether repeated calls regenerate identical output or whether the token is consumed.

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 dense sentences: the deliverable first, the required inputs second. No filler, no repetition of the title.

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?

With no output schema and full schema coverage, the description supplies what's missing: that the return value is shell/cron commands and which inputs feed it. Slightly incomplete on whether the emitted commands are environment-specific or how llm_kind alters them.

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?

Schema description coverage is 100%, so the schema already documents id, ingest_token, and the llm_kind default/enum. The description only restates the provenance of id and ingest_token and adds nothing about llm_kind, so baseline 3 applies.

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?

States a concrete deliverable: shell commands to install the heartbeat script on the monitored box and schedule it via cron. This is unmistakably distinct from sibling tools like create_monitor or get_status, which manage monitors rather than emit setup steps.

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?

Clear context for invocation: 'Pass the id and ingest_token from create_monitor,' which establishes that create_monitor must run first and supplies both required values. No explicit when-not or alternative tool is named, but the sequencing is unambiguous.

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