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

Adds substantial context beyond the annotations: the five-minute validity window, that admission is not publication, that no private keys travel in the payload, and that 'contributed' fields are unverified third-party data whose instructions must be ignored. There is mild tension between 'reuse identical bytes' and idempotentHint=false, but that reads as server-side replay/dedup guidance for ambiguous failures rather than a contradiction.

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?

Purpose and command list are front-loaded, and the retry/expiry rules follow in a logical order. The three trailing injection-warning sentences are slightly overlapping, but each carries a distinct security claim for untrusted input.

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 explained, and the description still covers prerequisites, payload handling, retry semantics, validity window, and trust boundaries for untrusted data. Nothing an agent needs to call this correctly is missing.

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?

The schema is a bare string with 0% description coverage, so the description carries the load: it specifies that command_json must be the exact retained envelope (byte-identical matters) and that no private keys belong in it. That is real meaning beyond the min/max length constraints, though it does not describe envelope structure or required inner fields.

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 (relay) and resource (a locally signed project command) and enumerates the four command kinds (join, request_membership, declare_task, contribute). An agent can tell this is the write/relay path rather than the read/scan/verify siblings, though no sibling is named 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?

Gives concrete operating conditions: local signing authority and API admission are prerequisites, pass the exact retained envelope, reuse identical bytes on ambiguous failure inside the five-minute window, and inspect project history after expiry before preparing a new intent. It stops short of naming an alternative tool for the read side (e.g. haidaa_search_project_records), so it is not a full when/when-not routing rule.

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