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

With no annotations, the description carries the full burden. It usefully discloses that the project is open, escrow-protected, and returns projectId and hireUrl. However it omits who funds the escrow, when funds are locked, fee implications, and whether the post can be cancelled or edited.

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 action and outcome, with return values flagged early. The final sentence is somewhat redundant with the second but does add actor context.

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 7-parameter mutation with no annotations and no output schema, the description partially compensates by naming the return fields. It still leaves the escrow lifecycle and permission requirements unexplained, which matters for a tool that moves money.

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 100%, so all 7 parameters are already documented. The description adds nothing about parameter effects (e.g. that deadlineHours or requiredSkills shape visibility or escrow terms), so the baseline 3 applies.

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 ('Post a machine-to-machine project to the marketplace') and clarifies the outcome ('Creates an open project with escrow protection'). It is clearly distinct from the escrow and booking siblings, though it never names an alternative tool explicitly.

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?

'Used by agents to post work they need done' implies the usage context but gives no when-not conditions, prerequisites, or pointers to related tools such as pabandi_start_escrow or pabandi_escrow_lock. The agent must infer whether escrow is set up automatically or requires a separate call.

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