Update an Identity

update_identity

DestructiveIdempotent

Update an existing identity: description and tags (removeTagKeys drops tags), its cloud-identity blocks (aws, gcp, azure, ngs; each replaces the stored block, and removeCloudIdentities detaches the ones it names), networkResources and nativeNetworkResources (each replaces the whole array), and the SpiceDB and memcache access lists. Provider blocks can modify real resources in the connected cloud account, including AWS IAM roles, GCP service accounts, and Azure managed identities. A new identity: create_identity. Giving one workload AWS, GCP, or Azure access: grant_cloud_access.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Input Schema

Name	Required	Description
`aws`	No	Replace the AWS cloud-identity block (full object). To switch xor-fields (roleName ↔ policyRefs), just send the new block — it replaces wholesale.
`gcp`	No	Replace the GCP cloud-identity block (full object). To switch xor-fields (serviceAccount ↔ bindings), just send the new block — it replaces wholesale.
`gvc`	Yes	GVC name.
`ngs`	No	Replace the NGS cloud-identity block (full object; it replaces wholesale). Shape: {cloudAccountLink, pub: {allow: [], deny: []}, sub: {allow: [], deny: []}, resp: {max, ttl}, subs, data, payload}; -1 means no limit.
`org`	No	Organization slug.
`name`	Yes	Resource name. Immutable: renaming is delete and recreate.
`tags`	No	Add or update tags without replacing the full set. Submit an empty list to clear all tags.
`azure`	No	Replace the Azure cloud-identity block (full object — it replaces wholesale).
`description`	No	New description for the identity.
`removeTagKeys`	No	Tag keys to remove from the resource.
`spicedbAccess`	No	Replace the SpiceDB cluster access list (max 5).
`memcacheAccess`	No	Replace the memcache cluster access list (max 5).
`networkResources`	No	Replace the full networkResources array (wholesale). Shape: [{name, agentLink, IPs: [ipv4] or FQDN, resolverIP, ports: []}].
`removeCloudIdentities`	No	Cloud-identity blocks to clear from the identity (e.g., ["aws"]). Server-side $drop semantics — use this to detach an identity from a cloud account.
`nativeNetworkResources`	No	Optional replacement for the full nativeNetworkResources array (wholesale). Each item requires name, ports, and exactly one provider block. Shape: [{name, FQDN, ports: [], and exactly one of awsPrivateLink {endpointServiceName} or gcpServiceConnect {targetService: projects/PROJECT/regions/REGION/serviceAttachments/NAME}}].

Output Schema

Name	Required	Description
`ok`	Yes
`data`	No	The full result. Read this, not only the summary.
`details`	No
`summary`	Yes
`nextSteps`	No

TDQS

A4.8/5.0

Behavior5/5

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

Goes well beyond destructiveHint/openWorldHint by naming the concrete real-world blast radius: provider blocks can modify AWS IAM roles, GCP service accounts, and Azure managed identities in the connected cloud account. It also discloses replace-wholesale vs. incremental semantics per field and clarifies removeCloudIdentities is detach ($drop) rather than deletion.

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?

Front-loaded with the resource and its mutable field groups, and every clause carries information. It is a single dense paragraph with long parenthetical clauses, though, which slightly hurts scanability for a 15-parameter tool.

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?

Given 15 parameters, nested provider blocks, destructive/idempotent annotations, and an output schema, the description covers every mutation group plus the cloud side effects an agent must weigh before calling. Nothing needed to call it correctly is missing, and return values are covered by the output schema.

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; the description earns an extra point by consolidating the replacement contract across all 15 nested parameters in one place ('each replaces the stored block', 'each replaces the whole array'), which is hard to see from scattered schema descriptions. It does not add format or example detail beyond what the schema already states.

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 and resource ('Update an existing identity') and enumerates exactly which fields it mutates: description, tags, cloud-identity blocks, network resources, and SpiceDB/memcache access. It is clearly distinguishable from create_identity and grant_cloud_access, both of which are named.

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

Usage Guidelines5/5

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

Explicitly routes the agent: 'A new identity: create_identity' and 'Giving one workload AWS, GCP, or Azure access: grant_cloud_access.' That is a when-to-use plus two named alternatives with their own conditions, which is the top of the scale.

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