download_release_asset

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

With no annotations, the description carries the full burden and does well: it discloses parallel ranged requests, mirror fallback across defaults, and sha256 verification when a digest exists. It omits overwrite behavior for existing files and auth requirements for private repos, which would matter for a mutating download.

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?

Three tight sentences, front-loaded with the action and mechanism, then the selection rule, then the integrity guarantee. No filler; every sentence informs.

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 an 8-parameter tool with no annotations and no output schema, the description adequately conveys mechanism, target selection, and verification. It leaves unaddressed where files land beyond the dest schema field and whether existing files are overwritten, but is otherwise self-sufficient.

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 75%, so the schema already documents tag, dest, mirrors, connections, and the name/pattern descriptors. The description adds genuine meaning by framing name and pattern as mutually exclusive alternatives (one asset vs several), beyond what the schema states individually. The undocumented owner/repo remain the gap.

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 and resource (download release asset) and describes mechanism (parallel ranged requests across mirrors). It differs clearly from the sibling list_release_assets, which discovers assets rather than fetching them.

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?

Explains how to select targets (exact name vs glob pattern), which is useful, but never states when to use this tool versus list_release_assets or any prerequisites (e.g., discovering names first). Usage context is implied rather than spelled out.

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