write_file

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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It clearly discloses that the tool can overwrite existing content, which is important mutation information. However, it does not mention persistence, whether the file is created if absent, permissions required, or side effects on the running pod.

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 tight sentence that front-loads the core operation, specifies the target resource, and adds the key differentiator (no full redeploy). Every clause carries meaning and there is no filler.

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?

For a tool with 4 parameters, no output schema, and no annotations, the description leaves important invocation details unexplained: how the target pod is identified, whether path is absolute or relative, which file states are overwritten vs created, and what response is returned. The description gives the purpose but not enough operational context for reliable 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 description coverage is 0%, and the description offers no parameter-level meaning beyond what the parameter names themselves imply. It does not explain what 'name' refers to, what 'path' should contain, how content is provided, or how encoding affects input. The description fails to compensate for the schema's lack of documentation.

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 ('Write (or overwrite)') and a clear resource ('a single file inside a pod's app root'), and immediately contrasts it with a full redeploy. This makes the tool's purpose clear and distinguishable from siblings like read_file, list_files, and deploy_pod.

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 phrase 'without a full redeploy' provides clear context for when to use this tool: when a file change should be applied directly to a running pod rather than through a redeploy. It does not explicitly name alternatives or exclusions, so it stops short of a 5.

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