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

With no annotations, the description carries the full disclosure burden. It does usefully cover the auth/security model ('Hosted signing, key used for this call only and never stored'), but says nothing about what the delivery changes, whether it is irreversible, what happens on failure, or rate limits.

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?

Two compact sentences with the core action front-loaded and the security caveat following. No filler, though the parenthetical about ronin_submit slightly muddles the single-action focus.

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 4-parameter mutation tool with no annotations and no output schema, the description covers the signing/storage behavior well but omits the task identifier semantics, error behavior, and outcome. Adequate but with clear gaps.

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 description coverage is only 25% (just 'secret'), so the description must compensate. It adds some meaning by indicating note is required and url is optional, but says nothing about the 64-hex 'task' identifier or note/url length or format constraints.

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 ('Deliver an accepted task') plus the payload it carries ('a note (and optionally a URL)'). It also distinguishes itself from ronin_submit by naming it as the self-signing alternative, so an agent can partially orient against siblings, though it does not clarify its boundary with ronin_complete/ronin_accept.

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 phrase 'accepted task' implies the precondition that the task must already be accepted, and the parenthetical 'or sign yourself with ronin_submit' names an alternative path. However, the alternative is about signing mode rather than tool selection, and there is no explicit statement of when not to use this tool.

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