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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so 'changes nothing' is largely redundant. 'Free' does add genuinely new information (no credit/cost impact) that annotations do not convey, which is the main value this sentence contributes.

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?

Two short sentences with the action front-loaded and zero filler; the cost/risk note is compact and earns its place.

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 zero-parameter, low-complexity introspection tool with no output schema, the description adequately conveys what is being fetched. It could be slightly more explicit about what the returned schema is used for (informing soclo_editor_edit calls), but nothing essential 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 tool takes zero parameters, so there is nothing to disambiguate and the description is not required to add parameter detail. Baseline 4 applies for a parameterless tool.

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?

Names a specific verb ('read') and a specific resource ('the schema for editor documents and render job fields'), which is clearly distinguishable from content-reading siblings like soclo_editor_read or soclo_editor_discover. It does not explicitly name those siblings, so sibling differentiation is inferred rather than stated.

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 when-to-use guidance: nothing says to call this before soclo_editor_edit or that it is the prerequisite for understanding the document format. 'Free; changes nothing' hints at cost/risk but does not route the agent among the other soclo_editor_* tools.

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