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

With no annotations supplied, the description does substantial work: it discloses provider selection and failover, the per-call price ($0.006 USDC on Base via x402), that payment occurs once, and that an all-provider failure returns 502 with no charge. Remaining gaps are page size/truncation limits and whether the agent can choose text versus markdown.

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 sentences, front-loaded with the capability and followed by economics and failure semantics; every clause carries information. The parenthetical about 'live Bazaar demand data' is mildly promotional but does explain how providers are chosen.

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 one-parameter, no-output-schema tool, the definition covers what is returned (clean text/markdown), cost, payment rail, and error semantics, which is enough to call it correctly. It stops short of stating limits on page size or content types that would make it fully self-contained.

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 single parameter (url) is fully documented in the schema as a public http(s) URL. The description reinforces scope with 'any web page' but adds no syntax, constraints, or edge-case handling beyond the schema, so the baseline of 3 applies.

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 and resource ('Read any web page as clean text/markdown') plus the delivery model (single paid call with automatic failover). It is clearly distinguishable from the search-oriented sibling intel_do_search, though it never names that sibling or any other 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?

Usage is implied: fetch a known public page and get clean text. There is no explicit when-to-use versus when-not guidance, no statement about JS-heavy or paywalled pages, and no routing advice toward intel_do_search or intel_find for discovery-type tasks.

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