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

With no annotations, the description carries the full burden and does reasonably well: it explains the firing condition ('fires if all of the signals go in force'), the default strict-setup-bar behavior (owner-list setups vs any docs reversal), and the shape of the return (count, % of basket, symbols, trigger, target, level of reclaim). It omits error behavior, cost/latency, and what happens when fewer than all signals fire.

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?

The opening definition is front-loaded, but the quoted 'Docs:' block restates the first sentence about concentration of signals in the same sector, and the phrase 'level of reclaim' is left unexplained. There is genuine waste and internal repetition in a description that is only a few sentences long.

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 5-parameter tool with a nested basket object and no output schema, the description is largely sufficient: it defines the computation, the strict-setup-bar switch, and the returned fields per symbol. What is missing is a note on partial matches (what if only some signals fire) and any guidance on basket sizing beyond the schema limits.

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%, so all five parameters are already documented in the structured field, making 3 the baseline. The description echoes the basket contract ('same bar format as find_signals') without adding syntax the schema lacks, and gives no extra meaning for now, as_of, or timeframe beyond what the schema states.

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 concrete verb+resource: it scans a basket of symbols for a concentration of setup bars in one direction and returns a ranked list per direction. That is specific enough to separate it from generic signal tools, but it never names or contrasts the closest siblings (find_signals, sim_breaks, signals_in_force) even though sim_breaks is an obvious near-duplicate.

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 context is implied rather than stated: the docs quote explains what makes a simultaneous break 'fire' (all signals in force), and the basket schema suggests swing vs intraday configurations. There is no explicit when-to-use / when-not-to-use guidance and no routing to alternatives such as find_signals for single-symbol work or sim_breaks for the adjacent concept.

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