record_decision

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

No annotations are provided, so the description carries full burden. It states the action ('record') but doesn't disclose behavioral traits like how the decision is stored, if it's immutable, requires permissions, or has side effects. This is a significant gap for a tool with mutation implications.

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, efficient sentence that front-loads the purpose and usage without any wasted words. It's appropriately sized for the tool's complexity.

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 no annotations and no output schema, the description adequately covers purpose and usage but lacks details on behavior, return values, or error handling. For a mutation tool with 6 parameters, it's minimally viable but has clear gaps in completeness.

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 fully documents all parameters. The description adds no additional meaning beyond implying the tool is for recording decisions, which aligns with the schema but doesn't enhance parameter understanding. Baseline 3 is appropriate as the schema handles the heavy lifting.

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 verb ('record') and resource ('architectural decision'), specifying it's for technical choices affecting codebase structure. It distinguishes from siblings like 'get_context' and 'get_gaps' by focusing on recording rather than retrieving, but doesn't explicitly differentiate beyond that.

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?

It provides clear context on when to use ('whenever you make a technical choice that affects the codebase structure'), which implicitly distinguishes it from sibling tools that likely retrieve information. However, it lacks explicit exclusions or named alternatives for similar recording tasks.

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