share_list

Read-onlyIdempotent

List active BCSE shares by issuer and trading-today status; returns shares and next_cursor. Use an issuer row from search_by_name. Example: {"issuer_uuid":"0d3bf3be","limit":20}.

TDQS

A4.2/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and idempotentHint=true, so safety is covered. The description adds behavioral context by mentioning it returns shares and next_cursor (pagination behavior) and clarifies 'trading-today status' semantics. It also indicates a dependency on search_by_name for the issuer_uuid. No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise: two sentences plus an example. It front-loads the purpose, states the output, gives a prerequisite, and provides a concrete example. Every word adds value, with no fluff or repetition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 5 optional parameters and an output schema, the description covers the essential purpose, the key input (issuer_uuid), the output (shares and next_cursor), and a usage example. It does not detail pagination parameters, but the schema covers those. The instruction to use search_by_name is a helpful prerequisite. It's complete enough for an agent to call correctly, though it could explicitly state that issuer_uuid is typically required for meaningful results.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema descriptions are comprehensive (100% coverage), including details like issuer_uuid format and is_trading meaning. The description adds an example that ties issuer_uuid and limit together, which aids understanding but doesn't introduce new parameter semantics beyond what the schema provides. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool lists active BCSE shares filtered by issuer and trading-today status, and returns shares plus next_cursor for pagination. It uses a specific verb (List) and resource (active BCSE shares), and distinguishes itself from siblings like share_get_by_uuid (single share) and trading_stats_get (stats) by focusing on the issuer-based list.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It provides clear context on when to use the tool: listing active shares by issuer, and explicitly instructs to use an issuer row from search_by_name, which is a prerequisite. However, it does not mention alternatives or when NOT to use this tool, such as for single-share lookup or stats. This is clear context but lacks exclusions, so a 4 is appropriate.

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