Secrets: create

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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=false, so the safety profile is covered externally. The description adds nothing beyond that: it does not say whether an existing key is overwritten, whether the write is idempotent, how errors on duplicate keys behave, or what the operation returns.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single front-loaded clause with zero padding, which fits a two-parameter tool. It is arguably over-terse rather than well-structured, since it conveys no more information than the title already provides.

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

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

For a secret-writing mutation the agent still lacks the essentials: overwrite semantics on duplicate keys, scoping to the current account or project, and any confirmation of success. Annotations cover only the abstract safety flags, and there is no output schema to fill the gap.

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

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

Schema description coverage is 100%, with both key and value documented inline including naming examples, so the baseline is 3. The description contributes no additional parameter meaning such as the value's expected encoding or the behavior of key reuse.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The phrase 'Store a new secret value' gives a concrete verb and resource, so the basic operation is identifiable. However, it offers no differentiation from the near-identical siblings secrets_update and secrets_list, so an agent cannot tell from the description alone why it should pick create over update.

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

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

There is no guidance on when to use this versus secrets_update, secrets_delete, or secrets_list, and no mention of prerequisites such as required scope or authentication. The only hint of context comes from the schema's note about non-interactive usage, not from the description.

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