RDS Hosts

ras_infra_get_rds_hosts
Read-onlyIdempotent

List RDS session hosts with hostname, IP, agent status, active sessions, CPU/RAM, and OS version to monitor health, check capacity, or troubleshoot RDS issues. Filter results by status or fields.

Instructions

List RDS session hosts — hostname, IP, agent status, active sessions, CPU/RAM usage, OS version. Use this to monitor host health, check capacity, or troubleshoot RDS issues. On large farms, narrow with filter (e.g. {status: 'online'}) or fields to keep responses small.

Input Schema

NameRequiredDescriptionDefault
limitNoMax rows after filtering. Default 50, max 200. Prefer narrowing with `filter` over raising the limit.
fieldsNoTop-level keys to keep on each row. Unknown keys are dropped. Use this to shrink large responses to only the columns you need.
filterNoEquality filter on top-level fields (AND across keys). String values match case-insensitively.

TDQS

A4.5/5.0
Behavior4/5

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

Annotations already declare readOnly/idempotent/non-destructive, so the safety profile is covered. The description adds operational context not in the annotations: large-farm response sizing and the recommendation to narrow with filter/fields. It does not contradict 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?

Three tight sentences; the core purpose and returned fields come first, followed by usage and sizing tips. No redundancy or filler.

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

Completeness5/5

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

With no output schema, the description usefully enumerates the returned shape and covers when to use it plus how to keep responses manageable. Nothing an agent needs to invoke this read-only list tool correctly is missing.

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

Parameters4/5

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

Schema coverage is 100%, so baseline is 3. The description adds a concrete filter example ({status: 'online'}) and the strategic advice to narrow rather than raise limit, which goes slightly beyond the schema's field-level docs.

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?

Names a specific verb (List) and resource (RDS session hosts) and enumerates the returned attributes (hostname, IP, agent status, active sessions, CPU/RAM, OS version). This makes it clearly distinct from the hostpool/agent siblings without needing to open either schema.

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?

Gives explicit use cases — monitor host health, check capacity, troubleshoot RDS issues — and practical guidance for large farms. It stops short of naming alternatives (e.g. ras_infra_get_rds_hostpools or ras_sessions_list) or stating when not to use it.

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