ci_create_binding

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

The description discloses key behavioral traits beyond what annotations (which are absent) would provide. It explicitly states that the tool does not sign or broaden authority, and clarifies that route_scopes are required for route deployment. It could be improved by mentioning what happens on success or error, but overall it is transparent about the tool's limitations.

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 extremely concise (3 sentences) and front-loaded with the purpose. Every sentence adds essential information without redundancy. The structure is logical: purpose, behavioral note, and a specific caveat about route_scopes.

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 high parameter count (10) and no output schema or annotations, the description covers the core behavioral aspects well. It explains the delegation flow and parameter importance. However, it lacks any indication of the return value or error conditions, which would be helpful for an AI agent to understand the tool's outcome.

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?

With 100% schema description coverage, the baseline is 3. The description adds value by explaining the role of the signed delegation (locally signed, not signed by the tool) and emphasizing the significance of route_scopes for route deployment. This additional context helps an AI agent understand parameter nuances beyond the schema.

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's purpose: creating a GitHub Actions CI/OIDC deploy binding. It uses a specific verb ('Create') and names the resource ('GitHub Actions CI/OIDC deploy binding'). It distinguishes itself from sibling CI tools (get, list, revoke) by specifying it is a creation operation.

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 provides clear context on when to use the tool (to create a binding) and includes important usage notes: the signed delegation must be created locally, and without route_scopes the CI cannot deploy route declarations. However, it does not explicitly list alternatives or situations where this tool should not be used.

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