ts_list_tables

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

No annotations are provided, so the description carries full burden. It does not state that the operation is read-only or non-destructive, but the action 'list' implicitly suggests no side effects. It could be improved by explicitly noting safety (e.g., 'This is a read-only operation'). No contradictions with annotations since none exist.

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, no wasted words. First sentence states the action, second adds critical context. Perfectly concise for the information needed.

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 simple listing tool with no parameters and an output schema, the description fully covers what the agent needs: what it does, why to use it first, and a crucial caveat about version differences. Complete and 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?

No parameters exist, and schema coverage is 100%. The description adds context about the database and version variations, which is useful for interpreting the output. Baseline for 0-parameter tools is 4, and this description meets it.

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?

Clearly states 'List every table in the Target Scheduler SQLite database.' Verb and resource are specific. Distinguishes from sibling tools like ts_describe_table and ts_read_table by its scope (all tables vs. specific table description/reading). The warning about version variations adds further clarity.

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?

Explicitly says 'Start here' indicating it is the first step for exploring the database. Warns about version-specific table names, guiding the agent to check before assuming. While it does not list alternatives explicitly, the broader sibling context (ts_describe_table, ts_read_table) implies when to use those instead.

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