delimit_loop_config

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

No annotations are provided, so the description carries the burden. It mentions that 'Only non-zero/non-empty values are applied', which is a useful behavioral detail. However, it does not disclose other behavioral aspects such as authentication requirements, rate limits, or what happens to existing configuration.

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 consists of two concise sentences, with the main action front-loaded. Every word contributes meaning without unnecessary elaboration.

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 has 7 parameters, no required ones, and an output schema, the description is adequate. It mentions the 'Pro' feature and the timing of configuration ('before starting a loop session'). It could be improved by noting that the output schema describes the updated configuration, but since an output schema exists, this is not a major gap.

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 input schema has 100% coverage with descriptions for each parameter. The description adds behavioral context beyond the schema by explaining that only non-zero/non-empty values are applied, which clarifies how default values (0, false, empty string) are handled.

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 explicitly states 'Configure the autonomous build loop safeguards (Pro)', clearly identifying the verb 'configure' and the resource 'autonomous build loop safeguards'. It distinguishes itself from siblings like delimit_build_loop and delimit_loop_status by focusing on configuration of safeguards.

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 usage before starting a loop session with 'Set limits before starting a loop session', but does not explicitly mention when to use this tool versus alternatives like delimit_build_loop or delimit_loop_status, nor does it provide when-not-to-use conditions.

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