create_integration_matcher

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

Annotations already declare the operation as non-read-only, open-world, non-idempotent, and destructive, so the safety profile is largely covered. The description adds the endpoint and a useful note that JSON-encoded string fields must remain strings. However, it does not describe required permissions, side effects, or response behavior for a create operation.

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 short sentences and front-loads the action. The endpoint and body-encoding caveat are immediately visible. There is no wasted prose.

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?

This is a create tool with a nested body object, three required parameters, no output schema, and no parameter descriptions in the schema. The description provides the HTTP endpoint and one encoding warning but leaves out the body fields, enums, required nested values, and expected result. It is not complete enough for an agent to invoke confidently without opening the schema.

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 but does not. It says to supply API fields in the body and warns about JSON-encoded strings, but it does not explain project_id, integration_id, or the nested fields key, name, value, method, match_type, and body_data_type. Agents must inspect the schema to understand most parameters.

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 verb and resource: adding an Integration Matcher. The POST path reinforces that this creates a matcher under a project integration. It does not explicitly distinguish itself from sibling tools such as update_integration_matcher or create_integration_value.

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 gives no guidance on when to use this tool versus update_integration_matcher, create_integration_value, or list_integration_matchers. It also omits prerequisites such as whether the integration must already exist. Usage is only implied by the name and HTTP method.

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