Github Update Release

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

Annotations already cover the safety profile (non-destructive, idempotent, open-world), and the description adds genuinely useful behavior beyond that: partial-update semantics ('Only the fields supplied are sent'), the fact that make_latest is deliberately not sent here, and a skill pointer for conventions. Minor gap in not stating permission requirements.

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?

Purpose is front-loaded in the first sentence, and the make_latest caveat plus workflow pointer are appropriately placed after it. The make_latest sentence is somewhat convoluted ('falls through to here') but each sentence carries non-redundant information.

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?

With an output schema present and annotations covering safety, the description need not explain return values. It adequately covers the mutation contract, the partial-update behavior, and the workflow pointer; only the draft/prerelease toggle semantics remain unaddressed.

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 only 43%, so the description should compensate. It does clarify the general partial-update contract and explicitly explains that make_latest is not a parameter of this tool, which helps avoid confusion with create_release. However, draft and prerelease semantics are left undocumented in both schema and description.

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?

States a specific verb+resource ('Changes a release in place, a draft included') and distinguishes itself from siblings by naming github_create_release explicitly and explaining what it does not do. An agent can tell this apart from create_release/delete_release without opening any schema.

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?

Gives concrete guidance for the tricky case: make_latest cannot be set here, so the agent is routed to delete-then-republish or the GitHub UI, and a workflow skill is referenced. It lacks a general when-to-use-vs-alternatives statement, but the alternative routing is explicit and actionable.

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