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

No annotations are provided, so the description carries the full behavioral burden. It does disclose the payload shape (packs, dimensions, checks, why-it-matters, how-to-fix), which is real value, and "List" implies a read-only, side-effect-free operation. However, it says nothing about pagination, ordering, or permissions, leaving gaps on a tool with zero annotation coverage.

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 that leads with the verb and enumerates the return contents compactly. No filler or redundant clauses; the only shortfall is the trailing list getting slightly dense.

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 and no annotations, the description adequately covers what the caller receives (dimensions, checks, rationale, remediation) and how the optional pack filter narrows it. Missing only edge details like scope of the unfiltered list and result ordering.

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% with a single optional "pack" param already documented as "core or ecommerce." The description restates those values ("core, e-commerce") and implies that omitting the filter surfaces every pack, adding only marginal semantics beyond the schema. Baseline 3 applies when the schema does the documenting.

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?

Specific verb ("List") plus a concrete resource (the rubric of packs, dimensions, and checks), and it even previews what each check includes (rationale and fix). An agent can tell it returns reference/rubric content rather than a score. It never names or distinguishes itself from the obviously related sibling get_ai_readiness_score, so it stops 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?

The sentence describes what is returned but gives no when-to-use signal, no exclusions, and no pointer to the alternative. For a rubric-listing tool sitting next to get_ai_readiness_score, the agent gets no guidance on choosing between reading the rubric and requesting a score.

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