ci_create_binding

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

With no annotations provided, the description carries full responsibility. It explains that the tool does not sign or broaden authority and clarifies the role of route_scopes. However, it does not disclose potential side effects (e.g., what happens if a binding already exists), authentication requirements, or error conditions, leaving moderate gaps.

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 consists of three concise sentences. The first sentence immediately states the tool's purpose, the second clarifies its limitations, and the third adds important nuance about route_scopes. No superfluous words, and the key information is front-loaded.

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 (10 parameters, no output schema, no annotations), the description covers the core behavior but omits return value information (e.g., what is returned on success or failure) and potential prerequisites (e.g., need for a locally signed delegation). The schema covers parameters well, but the overall context for using the tool in a workflow is only partially addressed.

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 coverage is 100%, so baseline is 3. The description adds value beyond the schema by explaining that without route_scopes, CI cannot deploy route declarations, and clarifying that signed_delegation is only sent, not signed by this tool. This extra context improves parameter understanding.

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 verb 'Create' and the resource 'GitHub Actions CI/OIDC deploy binding', and distinguishes it from sibling tools like ci_get_binding, ci_list_bindings, and ci_revoke_binding by specifying it sends a locally signed delegation. It also notes what the tool does not do (sign or broaden authority), providing a precise purpose.

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 context (creating a CI binding) but does not explicitly state when to use this tool versus alternatives like ci_revoke_binding or when not to use it. It mentions limitations (no signing, no broadening) but lacks explicit guidance on prerequisites or scenarios, resulting in only implied usage.

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