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

No annotations are provided, so the description carries the full burden and does well: it discloses data provenance (measured and computed by Cumulo from multi-region probes, relayed unchanged, with Cumulo credited), a trust caveat (validator names are typed by validators and marked untrusted), and a scope limit (only monitors Mocha testnet mocha-5 today). It stops short of stating read-only-ness or rate/latency behavior, keeping it from a 5.

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 well with the headline question, but the body is a single bloated run-on sentence enumerating overview elements ('whether enough stake... how many validators... how fast...') that largely duplicate the view enum in the schema. Routing guidance is clear but the middle needs trimming.

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?

With no output schema, no annotations, and 5 params, the description supplies the trust caveats, provenance, chain scope, and sibling routing an agent needs. It is close to complete; only the absence of any read-only/behavior framing and the redundant enumeration hold it back from 5.

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% and each param (view, chain, limit, range, period) is already documented with enums and defaults in the schema, so the baseline is 3. The prose lists the view names but adds no syntax or semantics beyond what the schema's per-view descriptions already carry.

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?

Opens with a specific question ('Is Celestia Fibre ready?') and names the resource precisely: the status of the Celestia Fibre network (CIP-51, validator-operated blob publishing) from Cumulo's Fibre Network Monitor. It also explicitly distinguishes itself from siblings (get_fibre_validator, get_fibre_blob_market, size_fibre_node), so an agent can route without opening schemas.

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 explicit routing: 'For one validator use get_fibre_validator; for blobs and fees use get_fibre_blob_market. For the hardware a Fibre node needs use size_fibre_node.' It also explains that a single 'view' parameter selects the aspect, covering when-to-use at both tool and parameter level.

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