Workflows: file handler example

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

readOnlyHint=true and openWorldHint=false already tell the agent this is a safe, non-network read, so the description only needs to add the output's nature. Saying the result is a 'copy-paste-ready' params JSON does add that it is a static template rather than live workflow state, but no further behavioral context is given.

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?

A single front-loaded sentence that tells the agent exactly what comes back, with no filler. It is arguably terse to the point of omitting routing guidance, but there is no wasted text.

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 zero-parameter helper with no output schema, the description does the one thing that matters: it characterizes the returned value as a ready-to-paste params JSON. What is missing is the pipeline context (which tool consumes that JSON), which the sibling list implies but the description never states.

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 tool takes zero parameters, which is the baseline-4 case — there is nothing for the description to disambiguate and the empty schema is fully documented at 100% coverage.

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?

States a specific verb ('Print') and a specific resource ('FileHandler params JSON'), which is enough to separate it from mutation siblings like workflows_file_handler_add. It does not, however, name the sibling it complements, so the distinction is inferred rather than stated.

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 explicit when-to-use guidance, no statement that this is a discovery/helper step to run before workflows_file_handler_add, and no exclusions. The use case is only implied by the name and the word 'example'.

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