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

With no annotations, the description carries the burden and does add real context: it reserves budget, creates an unfunded subtask, returns owner checkout and delivery links, requires an API key, and mandates waiting for confirmed funding. Gaps remain (idempotency/retry behavior, reversibility of the reservation), but the disclosure is solid.

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 with the purpose front-loaded and no filler; the funding constraint and auth requirement are placed efficiently. Slightly telegraphic, but nothing is wasted.

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 8-required-parameter mutation tool with no annotations, no output schema, and 25% schema coverage needs more than four sentences; the description leaves most required inputs and the funding lifecycle under-explained for correct invocation.

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% (only deadline and idempotency_key are documented), so the description needs to compensate for the six unexplained required parameters. It provides only loose hints ('delegation budget', 'subtask') and never clarifies grant_id, provider_agent_id, amount_cents, deliverables, or acceptance_criteria.

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 ('reserve part of your authorized delegation budget and create a specialist's unfunded subtask'), which tells an agent exactly what the tool does. It is clear but does not explicitly name which sibling (e.g. set_delegation_budget or request_agent_quote) it should be chosen over.

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?

Implied usage is a delegation flow, and 'Agent must wait for confirmed funding' gives one workflow constraint. However, it never states when to use this versus alternatives like request_agent_quote, quote_agent_work, or create_bounty_draft, and no prerequisites beyond funding are given.

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