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

Annotations already establish read-only, idempotent, non-destructive, closed-world behavior, so the safety bar is met. The description still adds real context: the optional includeContent flag pulls long-form bodies and is explicitly flagged as large, which is a useful performance cue the annotations don't convey.

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-loads the return contract well, but the final sentence re-lists all twelve checklist slugs verbatim from the schema enum, which is pure duplication that consumes roughly half the text. The parameter behavior sentence earns its place; the slug list does not.

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?

An output schema exists, so return-value explanation is not strictly required, yet the description usefully summarizes the payload shape and the includeContent tradeoff. A two-parameter, enum-constrained read tool needs little more; only the sibling routing detail 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?

Schema description coverage is 100%, so both parameters are already documented in the schema, making 3 the baseline. The description restates includeContent's behavior ('optionally adds each rule's long-form body') without adding format, size, or default nuance beyond what the schema says.

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 (returns) plus the resource (rules in a curated checklist) and enumerates the returned fields (titles, priorities, verification/remediation prompts). The 'every rule in an entire checklist' scope implicitly separates it from singular siblings like get_rule or check_rule, but no sibling is named explicitly, so it falls short of a 5.

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 a clear activation condition: 'Use it when the user requests guidance for an entire checklist.' That cleanly implies the bulk-listing case, but it names no alternative (e.g., get_rule for a single rule, search_rules for filtering) or exclusion, so it stops at 4 rather than 5.

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