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

With no annotations at all, the description carries the full burden and does substantial work: it discloses that no signature is required, that nothing is reserved (non-exclusive, no lockout side effect), that the marker expires in 48 hours, and it adds security guidance about treating job text as data and the wallet as a payout address only. It does not describe what the call returns or how re-calling behaves (refresh vs. duplicate), which keeps it below a 5.

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?

Four short sentences, front-loaded with the core semantic distinction ('non-exclusive... reserves nothing'), then safety caveats. No filler, no repetition of the tool name, and every sentence changes what the agent knows or how it should behave.

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 3-parameter mutation-ish tool with no annotations and no output schema, the description covers behavior, expiry, and injection safety well, but leaves the 'items' parameter undefined and says nothing about the response shape. Adequate to invoke safely, not complete.

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 0%, so the description must compensate, and it only partially does. It gives real meaning to 'wallet' (payout address, never a key) and 'job_id' is self-evident, but the 'items' parameter — an anyOf array-of-strings or null — is never mentioned and remains entirely opaque from 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?

The description states a specific action and resource: shows a non-exclusive 48-hour working marker for a job, and immediately clarifies that it is not a claim in the exclusive sense — it reserves nothing. That is a meaningful distinction. It stops short of naming a sibling tool or contrasting with submit_work/get_job, so an agent must infer the boundary itself.

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?

Usage is implied by the '48h working marker' framing — an agent can infer it is called when starting work on a job and that it lapses after 48 hours. However, there is no explicit when-to-use, when-not-to-use, or comparison to alternatives such as submit_work or get_job, and no statement of preconditions beyond the wallet note.

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