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

With no annotations, the description carries full burden. It discloses that the binding is immutable and that omitting version_id pins the current version, but it does not clarify side effects such as overwriting existing bindings, idempotency, or required permissions. Some transparency but incomplete.

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 concise sentences that front-load the primary purpose and then add key behavioral details. No redundant phrasing, though the structure could be slightly clearer with explicit parameter mentions.

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 an output schema exists, return values are not needed. However, the description omits details like what constitutes a compatible route or the exact meaning of catalog-only adapters, and it does not mention authentication prerequisites explicitly, leaving some ambiguity for an agent.

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 must explain parameters. It explains that project/environment arguments inherit the workspace binding when omitted and that version_id can be omitted to pin the current version, adding value beyond the schema's empty defaults. Alias is clear from the name.

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 resolves a project alias to an immutable alias-version binding for persistence in a project recipe, distinguishing it from sibling tools like hydracept_pinned_get or hydracept_pinned_run by specifying the recipe-pinning purpose and the catalog-only adapter restriction.

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?

It provides contextual hints like omitted arguments inheriting the authenticated workspace binding and the distinction between recipe pinning and generation, but does not explicitly name alternatives or state when not to use this tool. The guidance is implied rather than explicit.

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