Get key-value store record

get-key-value-store-record

Read-onlyIdempotent

Get the value stored under a specific key in a key-value store — a single record, not a listing of all keys. Requires the exact key name. The response preserves the original Content-Encoding; most clients handle decompression automatically.

USAGE:

Use when you need to retrieve a specific record (JSON, text, or binary) from a store.

USAGE EXAMPLES:

user_input: Get record INPUT from store abc123
user_input: Get record data.json from store username~my-store

Input Schema

Name	Required	Description	Default
`recordKey`	Yes	Key of the record to retrieve.
`keyValueStoreId`	Yes	Key-value store ID, name (resolved against your own key-value stores), or full name as username~name.

Output Schema

Name	Required	Description
`key`	Yes	Record key
`value`	Yes	The stored value (JSON, text, or binary)
`summary`	Yes	Summary of the result
`contentType`	No	MIME type of the stored value
`keyValueStoreId`	Yes	Key-value store ID

A4/5.0

Behavior4/5

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

Annotations already declare readOnly, idempotent, and non-destructive, so the safety profile is covered elsewhere. The description earns credit for adding behavioral context beyond that: the 'requires the exact key name' precondition and the note that the response preserves the original Content-Encoding, which most clients decompress automatically — a real return-value trait callers would otherwise trip over.

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?

The key facts — scope, exact-key requirement, encoding caveat — are front-loaded in three tight sentences. The subsequent USAGE and USAGE EXAMPLES blocks are somewhat redundant with the first paragraph, costing a little efficiency.

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?

A two-parameter read tool whose annotations, 100% schema coverage, and output schema already cover safety, inputs, and return shape. The description closes the remaining gap with the Content-Encoding behavior, which is exactly the non-obvious detail an agent needs.

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%, including the keyValueStoreId resolution rules (name vs. username~name) and minLength constraints in the schema itself. The description only reinforces that the key must be exact, adding little semantics beyond what the schema already documents, so the baseline 3 applies.

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 ('Get the value stored under a specific key in a key-value store') and preemptively scopes it against a listing tool: 'a single record, not a listing of all keys.' An agent can immediately tell this is a point lookup, not an enumeration.

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

Usage Guidelines3/5

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

It says when to use it ('when you need to retrieve a specific record (JSON, text, or binary)') and includes two concrete usage examples showing the store identifier formats. However, it never states when NOT to use it or names an alternative/sibling for enumeration, so the guidance is implied rather than comparative.

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