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

With no annotations, the description carries the full burden, but it does disclose a genuinely useful behavioral trait: results are truncated to the top 2 entries on public/free tier and complete only for pro. It says nothing about whether the call is read-only, what a matrix row contains, ordering, or rate/auth constraints.

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?

Very short and front-loaded, but the content is duplicated verbatim in Chinese and English, and the "[v1.6.0]" prefix is noise that consumes attention without helping selection. The tier constraint, the most useful sentence, is buried at the tail.

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 read tool with no annotations and no output schema, the description needs to say what comes back — columns, what "heat" means, ordering, or row identity — and it does not. An agent knows only that it gets up to 2 (free) or more (pro) rows of unspecified shape.

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?

Only one optional parameter (date) exists and schema description coverage is 100%, including the "omit for today" default. The description adds nothing about the date parameter, so the baseline of 3 applies — the schema is doing all the work.

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?

The description identifies a resource (a "tech-word heat matrix" / 技术日报词矩阵) but the noun is jargon — an agent cannot tell what the rows or values actually are. It is closer to a restatement of the name plus a tier note than a specific verb+resource statement, and it does not differentiate itself from siblings such as intel_tech_dir or intel_tech_launch.

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?

"与 /tech-daily 同一批行" hints at a related endpoint but no when-to-use / when-not-to-use rule or sibling alternative is given among the 16 intel_* tools. The only actionable guidance is the gating note (free = top 2 rows, pro = full table), which is about entitlement rather than tool selection.

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