Update a Global Virtual Cloud (GVC)

update_gvc

DestructiveIdempotent

Update a GVC (Global Virtual Cloud), the deployment scope that sets which locations its workloads run in. Scalars, description, tags, env, pullSecretLinks, and placement addLocations MERGE with existing values; remove* counterparts (removeLocations, removeTagKeys, removeEnvNames, removePullSecretLinks) take entries away, and remove* flags (removeLocationQuery, removeTracing, removeLoadBalancer, removeKeda, removeSidecarEnvoy, removeAliasWorkloadLink) delete an optional block entirely. The nested objects (loadBalancer, keda, tracing, sidecarEnvoy, locationOptions, locationQuery) are REPLACED wholesale: always submit the complete object, never a partial patch, or the omitted sub-fields are dropped. Custom domains are configured with the Domain resource (create_domain), not on the GVC. Placement and endpoint changes can redeploy workloads or affect public workload availability.

Input Schema

TableJSON Schema

Name	Required	Description
`env`	No	Add or update GVC environment variables (merged with existing). Submit an empty list to clear every env variable.
`org`	No	Organization slug.
`keda`	No	Replace the KEDA configuration.
`tags`	No	Add or update GVC tags (merged with existing tags) without replacing the entire set. Submit an empty list to clear all tags.
`gvcName`	Yes	GVC slug. If the user named none, list_resources (kind "gvc") and let them choose.
`tracing`	No	Replace the tracing configuration.
`removeKeda`	No	true deletes spec.keda.
`description`	No	New description. Treat it like a concise annotation for future operators.
`addLocations`	No	Placement locations to ADD (merged with existing; duplicates skipped). Accepts location names, friendly names, or links, validated against the org's own location list.
`loadBalancer`	No	Replace the GVC load balancer configuration.
`sidecarEnvoy`	No	Replace the Envoy sidecar filters (spec.sidecar.envoy).
`locationQuery`	No	Replace the dynamic placement query.
`removeTagKeys`	No	Tag keys to remove from the GVC.
`removeTracing`	No	true deletes spec.tracing (stops trace export).
`removeEnvNames`	No	Environment variable names to remove.
`locationOptions`	No	Replace per-location geo-routing options. Submit an empty list to remove them all.
`pullSecretLinks`	No	Add pullSecretLinks (merged with existing). Submit an empty list to clear them all.
`removeLocations`	No	Placement locations to REMOVE. Workloads redeploy out of removed locations and may lose capacity there.
`aliasWorkloadLink`	No	Link to a workload in this GVC whose canonical endpoint backs the GVC alias DNS record (e.g. //gvc/{gvc}/workload/{name}). NOTE: the alias is INERT while the target workload is suspended (suspend=true or maxScale=0) — it takes effect only while the workload runs.
`removeLoadBalancer`	No	true deletes spec.loadBalancer (reverts to platform default load balancing).
`removeSidecarEnvoy`	No	true deletes spec.sidecar (drops the custom Envoy filters).
`removeLocationQuery`	No	true deletes spec.staticPlacement.locationQuery, so placement follows the plain location list again.
`endpointNamingFormat`	No	Set the canonical endpoint subdomain format (default/legacy/org).
`removePullSecretLinks`	No	pullSecretLinks to remove (exact string match).
`removeAliasWorkloadLink`	No	true deletes spec.aliasWorkloadLink (detaches the GVC alias DNS record).

TDQS

A4.6/5.0

Behavior5/5

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

The annotations already flag destructiveHint=true and idempotentHint=true, and the description adds the precise degree of destruction: which fields merge, which nested objects are replaced wholesale, which flags delete entire blocks, and that placement/endpoint changes can redeploy workloads or affect public availability. This is exactly the additional context annotations cannot carry.

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?

A single dense paragraph that front-loads the resource definition before the merge/replace rules. Every sentence carries operational weight, though the merge/replace enumeration is heavy and could be marginally tightened.

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?

For a 25-parameter mutation tool with a rich output schema and full annotation coverage, the description supplies all the decisions an agent needs: what merges, what replaces, what deletes, and the side effects of placement changes. Nothing critical 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 the baseline is 3, but the description adds meaning the schema does not: the merge-vs-replace grouping across fields, the warning that partial nested objects drop omitted sub-fields, and the note that remove* flags delete blocks rather than clear entries. The only gap is it doesn't enumerate every parameter by name.

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?

States a specific verb (Update) and resource (GVC), and immediately defines what a GVC is ('the deployment scope that sets which locations its workloads run in'). This clearly distinguishes it from create_gvc and from unrelated update tools like update_domain or update_workload.

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?

Explains when to use merge fields versus remove* counterparts and remove* flags, and points the agent to create_domain for custom domains instead of configuring them here. It does not explicitly contrast with create_gvc or update_workload, but the operational guidance is strong and actionable.

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