Resumen de capacidad del entorno

env_capacity_overview

Read-only

Devuelve un resumen de capacidad del clúster: utilización de CPU/memoria, número de nodos y pods, y presión de recursos. El resultado incluye _signatureAscii: un gráfico ASCII de barras. Incluye siempre el contenido de _signatureAscii al final de tu respuesta en un bloque de código (```text) para que el usuario vea el gráfico.

TDQS

B3.4/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The description adds genuinely non-obvious behavior: the result contains a _signatureAscii ASCII bar chart and the agent is obligated to reproduce it in a ```text code block at the end of its answer. That output-presentation contract is real value beyond structured fields, though scoping behavior (per-env, per-window) is not described.

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

Conciseness4/5

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

Three short sentences, front-loaded with what the tool returns, then the output-format requirement. No filler or repetition, though the formatting instruction could be tightened.

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?

With an output schema present and annotations covering safety, the description is nearly sufficient for calling the tool. However, for a capacity-overview tool that overlaps heavily with env_health_summary and k8s_cluster_summary, the missing selection guidance leaves a real gap for the agent.

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?

Schema description coverage is 100%, so 'env', 'hours' and 'context_id' are already fully documented in the schema. The description adds no parameter-level detail beyond what the schema provides, so the baseline 3 applies.

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?

States a specific verb and resource ('Devuelve un resumen de capacidad del clúster') and enumerates the concrete contents: CPU/memory utilization, node and pod counts, and resource pressure. It is clear what the tool returns, but it does not differentiate itself from adjacent siblings such as k8s_cluster_summary or env_health_summary.

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?

There is no statement of when to use this tool versus alternatives, nor any prerequisites or exclusions among the many sibling observability/k8s tools. The only instruction given ('include _signatureAscii in your response') is about response formatting, not tool selection.

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