Secrets Manager Describe

aws_secretsmanager_describe

Read-only

Verify if a secret exists in AWS Secrets Manager and show its metadata (name, ARN, rotation, tags, dates). Does NOT return the secret value. Example: "does the secret prod/storefront/api-key exist?".

TDQS

A4.2/5.0

Behavior4/5

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

Annotations already declare readOnly, non-destructive and not-open-world, so the safety profile is covered structurally. The description still adds real value by disclosing that the secret VALUE is not returned and by listing the exact metadata fields an agent will get back, which prevents a wasted follow-up call.

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?

Three tightly packed sentences: capability, exclusion, and worked example, with the most important information front-loaded. No filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read-only describe call with an output schema and full annotation coverage, the description covers purpose, exclusion, and examples adequately. Only the relationship to the sibling list tool is left implicit.

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% with all four parameters documented, so baseline is 3. The description only echoes the secretId example format already present in the schema and says nothing about region/profile/context_id usage.

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 (verify existence) plus resource (secret in AWS Secrets Manager) and enumerates the metadata returned (name, ARN, rotation, tags, dates). The 'does the secret X exist?' framing makes clear this is a single-secret lookup rather than the bulk listing done by aws_secretsmanager_list.

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?

The example question ('does the secret prod/storefront/api-key exist?') gives a concrete trigger condition, and the negative constraint 'Does NOT return the secret value' steers the agent away from expecting a payload. It stops short of naming the sibling (aws_secretsmanager_list) or any alternative for retrieving the value.

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