Add or update secret file

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

Annotations already indicate idempotentHint=true and readOnlyHint=false, so the description adds minimal behavioral info beyond the underlying PUT API call. No contradictions, but little added value beyond annotations.

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?

Two sentences, no filler. Front-loaded with action and then scoping constraint + API reference. Every sentence adds unique value.

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?

Covers action, scope, and underlying API endpoint. Lacks detail on return value or behavior (e.g., whether update is merge or replace), but no output schema exists. Adequate for typical use.

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 coverage is 100%; every parameter is described. The description does not enrich parameter meanings (e.g., what format 'content' should be). Baseline score of 3 applies since no additional semantics beyond schema.

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?

Clearly states verb (add or update) and resource (secret file for a service). Distinguishes from siblings by specifying it applies only to files set directly on the service, not those in linked environment groups. Unique among sibling tools like render_delete_secret_file and render_update_secret_files_for_service.

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?

Provides clear context on when to use (for secret files directly on a service) and when not (for files in linked environment groups). Does not explicitly list alternative tools but the scope limitation guides correct usage.

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