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

With no annotations, the description carries the full behavioral burden. It does disclose the internal process (six analysis modules) and the output structure (tiers, root causes, prioritized action list), which is real value. But it never says how the 'multi-format store documents' reach the tool, whether the run is expensive/long, or what happens when a module lacks data — notable gaps for a multi-stage analysis pipeline.

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 tightly packed sentences with no filler, front-loaded with the action and scope; the second sentence covers output and downstream handoff. Minor softness in "bridges to supply-chain and HR experts", which is motivational rather than operational, but nothing 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 complex six-module pipeline with no annotations and no output schema, the description should explain input expectations and output shape more concretely. It covers the conceptual output well, but leaves the input contract (how store documents are provided) and result format unspecified — an agent knows what it gets but not exactly what to supply.

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% for the single optional 'query' parameter, so the schema already defines it and baseline 3 applies. The description adds nothing about the parameter — notably, it never explains that documents are apparently supplied out-of-band and that 'query' only scopes the resulting brief.

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?

Uses a specific verb pair ("Parse ... run six business-analysis modules") and enumerates the exact domains covered (revenue, traffic, menu, member, operations, finance), plus states the deliverable (problem tiers, root causes, prioritized actions). An agent can tell what it produces. It stops short of naming which near-identical siblings (fnb-store-diagnostic, sanhao-ops-diagnostic) it should be preferred over.

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?

Usage is only implied by the enumerated modules — an agent can infer this is for a full-store health check rather than a single-metric analysis, and that it feeds downstream supply-chain/HR work. There is no explicit when-to-use, when-not-to-use, or prerequisite (e.g. what documents must exist before calling).

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