perf_create_budget

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

With no annotations, the description carries the full burden of behavioral disclosure. It does communicate that this is a mutating action and that CI/CD enforcement is involved, but it does not explain whether it writes files, modifies pipeline configuration, requires authentication, triggers side effects, or what happens to existing budgets.

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 one concise sentence with no filler, and it front-loads the core action plus the CI/CD enforcement angle. It could carry more useful detail, but what is present is efficient.

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 output schema and no annotations, this description is incomplete for a mutating tool. It does not describe return values, success/failure behavior, where the budget is stored, whether CI/CD files are edited, or what 'Pro feature' means operationally. An agent can identify the tool but not confidently invoke it without guessing.

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 description adds no parameter-level meaning beyond what the schema already states. While app_type and sla_target have schema descriptions, api_key remains undocumented and the 'Pro feature' hint only weakly implies why an API key might be needed. The agent is left to infer parameter roles from the schema alone.

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 clear verb and resource: 'Create a performance budget configuration' with CI/CD enforcement, which distinguishes it from related performance helpers like perf_generate_load_test or perf_analyze_bottlenecks. It is specific enough to identify the tool's core job, though it does not explicitly name a sibling tool.

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?

There is no guidance on when this tool should be used versus alternatives, nor any indication of prerequisites such as an existing CI/CD pipeline, repository, or performance baselines. The description implies usage but does not state when not to use it or what setup is assumed.

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