update_tech_stack

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

With no annotations provided, the description carries full responsibility for disclosing behavior, but it only states 'update' without explaining partial update semantics, error handling, idempotency, or response format. This is a serious gap for a mutation tool.

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, concise sentence with no redundancy, front-loading the core purpose. However, its brevity borders on under-specification, lacking any structured detail beyond the bare statement.

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 nested 'updates' object, required parameters, and no output schema, the description is woefully incomplete. It doesn't explain partial update behavior, required fields, or return values, making it difficult for an agent to use the tool correctly.

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 has only 50% description coverage, with 'id' described but 'updates' not. The description does not compensate by explaining the structure of 'updates' or its fields, leaving agents to infer from property names (version, framework, etc.).

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 identifies the action ('Update') and the resource ('existing tech stack entry'), distinguishing it from siblings like add_tech_stack and remove_tech_stack. However, it lacks specificity about what aspects can be updated, which is conveyed only through the schema.

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, such as when to use add_tech_stack for new entries or how to handle specific fields. No prerequisites or exclusions are mentioned.

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