strata_render_chart

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

No annotations are provided, so the description must carry the behavioral burden. It says 'Render a chart' but does not disclose whether it writes a file, overwrites existing output, validates the spec, or what side effects occur. The out_path parameter hints at file creation, but this is not explicit.

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 filler. It front-loads the primary action. The phrase '(path, status)' is somewhat cryptic but does not add unnecessary length.

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 no annotations and minimal parameter documentation, the description does not provide enough context about expected inputs, output file behavior, or how this tool relates to strata_chart_templates. The output schema exists but the description still leaves key invocation details ambiguous.

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%, so the description must compensate. It adds some meaning by identifying spec_yaml as a Vega-Lite template and data_json as JSON data with 'path, status' fields, while out_path is self-explanatory. However, it lacks format details, required field structures, and relationship between template and data.

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 states a specific action ('Render a chart') and identifies the key inputs: a Vega-Lite template and JSON data. It is distinct from sibling tools like strata_chart_templates, though it does not explicitly contrast itself with them.

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 offers no guidance on when to use this tool versus alternatives, nor does it mention prerequisites or exclusions. Usage is only implied: use it when you want to render a chart.

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