get_systemd_list_timers

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

The description does not disclose behavioral traits beyond the basic action. It fails to mention that the tool connects to remote hosts (as indicated by schema parameters like host, user, password), requires authentication, or that it is a read-only operation. Without annotations to supplement, the description carries the full burden and falls short.

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 extremely concise: a single sentence with an emphasis. It avoids unnecessary words. However, the conciseness comes at the cost of completeness; it is efficient but could be considered under-specified for a tool with many parameters.

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?

Given the tool's complexity (7 parameters, remote execution implied by schema), the description is severely incomplete. It does not explain that this is a remote SSH-based tool, how to handle authentication, or what the output schema yields. An output schema exists but its content is unknown; the description should provide at least a summary of the return format.

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 0%, meaning none of the 7 parameters have descriptions. The description adds no information about any parameter, such as the meaning of 'host', 'user', or 'password'. The statement 'Lists all systemd timers' does not clarify the role of parameters. The agent receives no help understanding how to populate the inputs.

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 'Lists all systemd timers' and emphasizes its purpose with 'USE THIS TOOL to check for timers.' It is specific about the resource (systemd timers) and action (lists). However, it does not explicitly differentiate from sibling tools like get_systemd_list_all or get_systemd_list_failed, which could list timers as part of a broader set.

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 provides a usage directive ('USE THIS TOOL to check for timers'), which gives context for when to use it. However, it offers no guidance on when not to use it, no mention of alternatives (e.g., get_systemd_list_all for all units), and lacks prerequisites or contextual hints about remote execution.

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