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

With no annotations, the description carries the full burden and does well: it discloses the 6-month window, the critical limitation that no per-customer rate is computable because PUCT publishes no customer counts, and the free/pro and commercial-use restrictions. It omits pagination/return-shape behavior, keeping it short of a 5.

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 core resource and scope, then adds licensing and tier caveats. Dense but each sentence carries information; no filler, though the licensing sentences are somewhat tangential to calling the tool.

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?

No output schema or annotations exist, so the description must stand alone, and it adequately explains what is returned (complaint counts by category, entity, and brand) plus data limitations. The main gap is the undocumented pagination parameters.

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 coverage is only 33% and the description does not compensate: limit and offset are never explained, and the provider filter is only obliquely hinted at via 'per Texas retail electric provider'. It adds essentially no semantics beyond the single schema-documented parameter.

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 precise verb+resource: PUCT customer complaint counts per Texas retail electric provider, broken out by category and with associated Power to Choose brands. An agent can immediately distinguish this from price/grid/plan siblings such as electricity_plan or market_grid.

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 tier conditions (free = latest window, Pro = older windows) and licensing terms, which imply when the tool is usable. However, it names no sibling alternative and gives no explicit 'use this instead of X when Y', so routing guidance is only implied.

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