update_credentials

Update Immich server URL and API key, validating new credentials before applying. Persists changes and swaps the live connection.

Instructions

Update the Immich connection credentials. Use this when the API key has been rotated or the server URL changed. Validates credentials before applying. Side effect: persists new credentials to disk and hot-swaps the live connection.

Args:
    base_url: Full Immich server URL including protocol (e.g. 'https://photos.example.com').
    api_key: A valid Immich API key (generated in Immich > User Settings > API Keys).

Returns: JSON with success status, photo/video counts confirming access, and persistence path.

Behavior5/5

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

Discloses side effects: persists to disk, hot-swaps live connection, and validates credentials. Also mentions return structure (success status, counts, persistence path). No annotations provided, so description fully covers behavioral traits.

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?

Concise with no wasted words. Structured in clear paragraphs: purpose, when to use, side effects, args, returns. Front-loaded with purpose.

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?

Covers all necessary aspects: purpose, usage, behavior, parameters, and return. Output schema exists, so return details are sufficient.

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

Parameters5/5

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

Schema has 0% description coverage, but the description adds detailed explanations for both parameters, including expected format and example for base_url, and origin for api_key.

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?

Clearly specifies the verb 'Update' and the resource 'Immich connection credentials'. Distinct from sibling tools like get_connection_info (read-only).

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?

Explicitly states when to use: when API key is rotated or server URL changed. Does not mention when not to use, but the use case is specific enough.

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