pg_list_triggers

List all triggers in a PostgreSQL schema, filtered by schema name or using the default schema.

Instructions

List all triggers in the specified schema.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
schemaNoSchema to filter by. Defaults to the connection's defaultSchema (or 'public').
connectionIdNoId of the postgres connection to use, from databases.config.yml. Optional when only one postgres connection is configured.
Behavior2/5

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

With no annotations provided, the description must fully disclose behavioral traits. It states the tool lists triggers, implying a safe read operation, but it lacks details on whether it queries system catalogs, potential performance impact, or the exact scope of 'all triggers' (e.g., user-defined only).

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 a single, concise sentence that directly conveys the tool's purpose. Every word adds value, and it is appropriately sized for a straightforward list tool.

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

Completeness3/5

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

Given the lack of an output schema, the description should ideally mention what the returned data contains (e.g., trigger names, definitions). While the tool is simple, omitting output details leaves the agent uncertain about the result format.

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 input schema covers both parameters with descriptions, achieving 100% schema coverage. The description adds no additional semantic meaning beyond what is already in the schema, meeting the baseline expectation.

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

Purpose4/5

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

The description clearly states the verb 'List' and the resource 'triggers', specifying the scope 'in the specified schema'. It effectively distinguishes from sibling tools that list other database objects (e.g., pg_list_tables, pg_list_views). However, it could be more explicit about the specific filter (schema) and that triggers are from the current connection.

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

Usage Guidelines2/5

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

No guidance on when to use this tool versus alternatives like pg_list_constraints or pg_list_functions. The description provides no context for when this tool is appropriate, nor does it mention any prerequisites or exclusions.

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