set_chart_series_action

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

With no annotations provided, the description adds behavioral context: schema-aware insertion respects ChartSeries child order and the operation is idempotent on structural equality. However, it does not disclose side effects, permission requirements, or error behavior.

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 three sentences: first states the core purpose, second clarifies similarity and addressing, third adds behavioral notes. It is front-loaded and efficient, though the reference to sibling tools could be considered slight redundancy.

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 the tool has 6 parameters (5 required) and no output schema, the description covers action types, addressing, idempotency, and child order. However, it lacks full parameter explanations and does not describe return values, leaving gaps for an agent unfamiliar with sibling tools.

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 explains the action_type enum values, implies drillthrough_parameters is optional for Drillthrough, and defines addressing via chart_name and series_name. However, it does not detail the other parameters (path, target_expression), relying on the user's familiarity with sibling tools.

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 the tool sets an action (Hyperlink, Drillthrough, BookmarkLink) on a ChartSeries. It distinguishes itself from sibling tools like set_textbox_action and set_image_action by specifying the addressing pattern (chart_name, series_name) and shared kwarg surface.

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 implies usage for chart series actions by mentioning the addressing pattern and similarity to other action-setting tools, but it does not explicitly state when to use this tool versus alternatives or when not to use it.

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