Execute TOCA Capability

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

Annotations indicate readOnlyHint=false, openWorldHint=true, idempotentHint=false, destructiveHint=false. The description adds no behavioral context beyond the annotations: it does not explain what side effects occur, whether it can be safely retried (idempotency is mentioned as a step but not described), what happens on failure, or what 'audit' means. There is no contradiction, but the description's cryptic phrasing ('provider read-back') offers little actionable transparency.

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?

One sentence, brief, but it is a terse list of technical jargon without context. It is not 'concise' in the meaningful sense; it is under-specified. It does front-load the main verb 'Execute', but the rest is opaque.

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?

Given the complexity (4 parameters, no output schema, no parameter descriptions, rich annotations like openWorldHint and idempotentHint), the description is severely incomplete. It does not explain return values, error states, or how this relates to the approval and workflow siblings. The agent would likely need to consult capability descriptions or documentation to use this tool correctly.

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 0%, so the description must compensate. It does not explain the meaning of capabilityId, payload, correlationId, or approvalId. For example, it doesn't clarify what a 'capability' is, what format payload should take, or how to obtain an approvalId. The description's mention of 'typed schema' and 'approval' hints at the payload and approvalId, but it is too vague to help an agent construct a valid call.

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 description is a dense list of internal resolution steps ('Resolve identity, capability, typed schema, policy, risk, approval, idempotency, handler, provider read-back and audit') but fails to state the actual verb and resource: what does 'execute' do? It implies executing a capability, but the description reads like an implementation checklist rather than a user-facing purpose. It does not clearly distinguish from siblings like toca.verify or toca.workflow.advance, which are also execution-related.

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?

No guidance on when to use this tool versus alternatives. It does not mention when to use toca.workflow.create, toca.approval.request, or toca.verify instead. The list of resolution steps implies it is the final execution step after approvals, but this is not explicitly stated, leaving the agent to guess context.

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