update_workflow_activity

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states this is an update operation (implying mutation) but doesn't describe what 'update' entails—whether it overwrites or merges fields, if changes are reversible, what permissions are needed, or what happens on success/failure. For a mutation tool with zero annotation coverage, this leaves critical behavioral aspects unspecified.

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, direct sentence with zero wasted words. It front-loads the core action and target efficiently, making it easy to parse. Every word earns its place by conveying essential purpose.

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 complexity (a mutation tool with nested parameters) and the lack of annotations, schema descriptions (0% coverage), and output schema, the description is incomplete. It doesn't explain what can be updated, how updates behave, or what the tool returns, leaving significant gaps for an AI agent to infer correctly.

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 description provides no information about parameters, and the schema description coverage is 0% (no descriptions in the schema). With 1 required parameter ('params') that contains nested properties (activity_id, name, description, attributes), the description fails to compensate for the complete lack of schema documentation, leaving all parameter meanings unclear.

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 action ('Update') and target ('an existing activity in a workflow'), making the purpose immediately understandable. It distinguishes itself from siblings like 'add_workflow_activity' (create) and 'delete_workflow_activity' (remove), though it doesn't explicitly contrast with 'update_workflow' (which modifies the workflow itself rather than activities).

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?

No guidance is provided on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an existing activity ID), constraints (e.g., permissions required), or when to choose this over similar tools like 'reorder_workflow_activities' or 'update_workflow'. The description assumes context without providing it.

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