Create Agent Wallet

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

With no annotations, the description carries the full burden, and it does add real behavioral context: a vault-secret file is created automatically, and the private key is deliberately never returned. It is silent on important traits for a key-generating mutation, such as whether it fails or overwrites when a wallet already exists, where state is persisted, and whether the operation is idempotent.

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?

Three short sentences with no filler, and the core purpose plus the two most load-bearing facts (auto vault-secret creation, no private key returned) are front-loaded. It could be marginally tighter, but every sentence earns its place.

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?

With no output schema and no annotations, the description does the important work of declaring the return values (address and profile IDs), which is exactly what an agent needs to chain into later calls. It stops short of clarifying what 'profile IDs' refer to relative to the execution-profile siblings, but the essentials are covered.

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?

There is a single optional parameter ('label') and schema description coverage is 100%, so the schema already documents it fully. The description adds no extra meaning about the label's role (e.g., whether it must be unique or whether it can be changed later), so the baseline 3 applies.

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?

States a specific verb and resource ('Create a local encrypted agent wallet'), and the qualifier 'local encrypted' distinguishes it from a remote/custodial flow. However, it never contrasts itself with the closest sibling, agent_import_wallet, so an agent must infer which of the two wallet-creation paths to pick.

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 when-to-use guidance at all: no statement of when to call this versus agent_import_wallet, versus agent_list_wallets/agent_get_wallet, and no prerequisite (e.g., does an existing wallet need deletion or reset first?). Usage is only implied by the verb 'create'.

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