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

With no annotations, the description carries the full burden, and it does well: it discloses that the text is relayed verbatim rather than summarized, defines the fallback source (Upgrade Notice of the latest stable celestia-app release) for the newest uncovered version, and scopes the tool to Celestia only. It does not mention read-only nature, response size, or rate limits, but the fidelity and fallback disclosures are genuinely informative.

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 with the purpose and the topic list, then the invocation rules and the sibling pointer. The middle sentence is a dense run-on covering six topic areas, but nothing is redundant with the schema.

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?

No output schema and no annotations, but the description explains content provenance, fallback behavior, and argument combinations, and the outline/full distinction is covered by the schema. An agent has enough to call it correctly; minor gaps are the absence of any note on output size or verbosity.

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 coverage is 100% and the schema already documents each parameter, so baseline is 3; the description goes beyond it by explaining the combinatorial semantics (from_version and to_version together yield every intervening version, omission yields the newest) that no single schema field states.

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+resource: it returns what a Celestia node operator must know and do per consensus app version, sourced from official release notes, and enumerates the covered topics (OS/glibc, binary, config, KMS, pruning, Fibre). It is clearly distinguishable from search_release_notes (raw search) and get_celestia_upgrade_status (current version/signal), which it names.

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?

Explicitly prescribes argument combinations: from_version+to_version for a range, to_version alone for one version, nothing for the newest. It also routes to a named sibling, get_celestia_upgrade_status, for the related but different question of what mainnet runs now.

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