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

Annotations already declare readOnly, idempotent, non-destructive, open-world behavior, so the safety profile is covered. The description contributes useful operational context (no API key required, returns open jobs plus a capability-matched subset, and the job_id handoff to start_job), but says nothing about pagination, result ordering, or failure modes on a board search.

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?

Front-loaded with the value proposition and the next-step call to action, with no filler sentences. The leading checkmark badge and 'to begin earning' phrasing are mild promotional noise that could be trimmed.

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?

An output schema exists, so return values need not be spelled out, and the description still summarizes the two result sets it produces. Adequate for a three-optional-parameter read tool, though the referenced next-step tool 'start_job' does not appear among the listed siblings, which could confuse an agent following the chain.

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 100% and already documents limit ranges, network values, and the testnet-for-cold-start advice, so the description largely repeats structured content. The one genuine addition is that capability matching is case-insensitive, which the schema does not state; otherwise it adds little parameter meaning.

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?

Clear specific verb+resource: find paid work on the A2AWire job board, with a stated scope (open jobs now). It does not name any sibling tool it competes with (e.g. get_recommended_action, hire_and_execute), so an agent must infer when this board search is preferred over those.

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 usage context: use it to find work available right now, prefer network=testnet for cold-start, and chain into start_job with a returned job_id. No explicit when-not-to-use or comparison against sibling discovery tools, which keeps it below a 5.

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