github_create_deployment_status

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

Annotations already convey readOnlyHint=false, destructiveHint=true, and idempotentHint=true. The description adds context beyond those: routing is restricted to the governed project/account connector authority, the claimed effect is verified by the platform, and writes may be resumed via an approval_ref. However, it does not disclose what side effects the operation has on the GitHub resource it targets.

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 argument list is tidy and every line earns its place with no fluff. However, the allocation is lopsided: seven lines on parameter glosses and zero lines on what the operation actually does. It is well-organized but mis-focused, spending its budget on plumbing metadata rather than operational meaning.

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?

For a 7-parameter tool with 0% schema coverage, the agent cannot determine what to place inside the `arguments` JSON to create a deployment status (e.g., the required state field, the deployment identifier, environment context). Output schema and annotations cover return format and safety profile, but the core invocation payload semantics are absent, leaving the tool effectively uncallable without external knowledge.

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 0%, so the description carries the full burden and does list all 7 parameters with glosses. The most useful is 'arguments: JSON string of arguments for the connector operation,' which signals where the real GitHub payload goes. But several glosses are near-tautological ('Exact project correlation reference', 'Project-bound connector account alias') and give no hint of what values to supply, so compensation is only partial.

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 opens by restating the tool name verbatim ('Github connector operation `create_deployment_status`'), which is a tautology. It never explains what a deployment status is, what creating one does to a GitHub deployment, or how it differs from sibling operations like github_list_deployments or github_create_check_run. An agent must infer all semantic meaning from the name alone.

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 given on when to use this tool versus alternatives, what preconditions exist (e.g., a deployment must already exist), or what workflow would require a deployment status. The governance-routing sentence is about mechanism, not usage. With dozens of github_* siblings, the agent gets no help selecting this one.

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