add_tech_stack

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

With no annotations, the description carries the full burden of disclosing behavior, but it only states the action. It does not mention whether adding a tech stack entry overwrites existing entries, whether the project must already exist, or any validation/error behavior. This is a significant transparency gap.

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, direct sentence that is front-loaded with the action and object. Every word is meaningful, and there is no redundancy or filler. It is appropriately concise for a straightforward add operation.

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 nested parameter object, lack of annotations, and absence of an output schema, the description is too minimal. It does not explain return values, side effects, prerequisites, or how it relates to sibling tools like update_tech_stack and get_project_configuration. This leaves important gaps for an agent to safely invoke the tool.

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 schema provides descriptions for projectId and the nested properties of techStack, but the techStack parameter itself lacks a description. The tool description loosely refers to it as a 'technology stack entry' but adds little structural or semantic detail beyond what the schema already offers. With 50% top-level coverage, the description only partially compensates.

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 uses a specific verb ('Add') and identifies the resource ('technology stack entry') and target ('project configuration'), making the tool's function clear. However, it does not differentiate from sibling tools like update_tech_stack or remove_tech_stack, so it falls short of a 5.

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 no guidance on when to use this tool versus alternatives. It simply states the action without any context, prerequisites, or exclusions, leaving the agent to infer usage from the name alone.

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