get_json

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

With no annotations, the description carries the full safety/behavior burden. It does disclose the meaningful constraint that only published documents are fetchable, but it says nothing about password-protected documents (a third parameter exists for this), error behavior for missing or unpublished IDs, or what form the payload takes.

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?

A single front-loaded sentence with zero filler — the resource and lookup keys come first. It is arguably too terse for a tool with an optional auth-ish parameter, but nothing in it is wasted.

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 simple three-parameter read tool with no annotations and no output schema, the essentials are present, but the description leaves open how the JSON is returned and how protected documents behave. A reader can call it correctly but not predict its failure modes.

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% (id, namespace, password all documented), so the baseline is 3. The description restates the two required keys but adds no meaning beyond the schema, and the optional password parameter is not mentioned at all.

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 (Fetch), the exact resource (published BrewPage JSON document), and the lookup keys (namespace and ID). The 'JSON document' qualifier distinguishes it from the page/kv siblings, though it never names an alternative 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?

There is no statement of when to use this tool versus get_page, get_kv, or search_gallery. The only implicit hint is the word 'published', which suggests drafts are not retrievable here, but no condition or exclusion is spelled out.

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