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

With no annotations provided, the description carries the full burden of disclosing read/write behavior and side effects. It only adds 'Free' and a settlement hint, but does not state whether this is a read-only overview, what data it returns, or whether invoking it has side effects. The claim that it registers nodes, posts bounties, and claims work implies mutation unsupported by the schema, leaving behavior ambiguous.

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?

The text is short, but brevity is not clarity: the lead phrase lacks an action verb, the list of actions belongs to sibling tools, and the settlement note is off-topic for a simple limit-only call. This is under-specification rather than economical structuring.

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?

Although the output schema helps with return shape and the tool is simple, the description still fails to define the core operation, its scope, or its relationship to the sibling mesh_* tools. It leaves basic questions unanswered, such as whether the ledger lists nodes, bounties, work claims, or all three, and whether invocation is read-only or mutating.

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's only parameter, limit, has zero description coverage, and the description never mentions it. With schema_description_coverage at 0%, the description needed to compensate by explaining the limit semantics but did not, so agents must guess whether the integer controls page size, max results, or some other behavior.

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 identifies a resource ('Kairos agent mesh board') but never states the operation being performed. The phrase 'register nodes, post open bounties, claim work' describes actions owned by sibling tools (mesh_register_node, mesh_post_bounty, mesh_claim_bounty), so an agent cannot tell whether mesh_ledger lists, creates, or mutates. 'Mesh Ledger' and 'mesh board' are near-tautological and do not clarify that the tool takes only a limit parameter.

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?

No when-to-use or alternative-selection guidance is provided. The description mentions acceptance_digest and digest_tool_result/verify_tool_result_digest for settlement but never explains how mesh_ledger relates to the mesh_* siblings; in fact, it conflates their actions with this tool, which would mislead an agent deciding between mesh_ledger and mesh_list_bounties or mesh_list_nodes.

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