sentinel_verify_chain_integrity

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

With no annotations provided, the description carries the full burden. It explains the underlying mechanism (each entry hash-chained to previous) and the outcome (detects tampering), which adds genuine behavioral context. However, it doesn't disclose side effects (presumably none as a check), return format, or failure behavior, though for a non-destructive verification tool the provided detail is reasonable.

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?

Two sentences, front-loaded with the action verb and resource. The second sentence adds the mechanism explanation, which earns its place. No filler or unnecessary phrasing.

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 zero-parameter, no-output-schema verification tool, the description conveys the essential purpose and mechanism clearly. It explains what the check detects (tampering) and how (hash-chaining). It could mention what the return indicates (pass/fail) but given the absence of an output schema, this is a minor gap rather than a significant deficiency.

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?

The tool has 0 parameters, so parameter semantics are trivially satisfied. The description's mention of the 'entire ledger' scope clarifies there are no options to narrow or filter, which aligns with the empty schema. This dimension has no real burden.

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 uses a clear verb ('Verify') with a specific resource ('cryptographic integrity of the entire provenance ledger'). It distinguishes the intent (detect tampering) but doesn't explicitly differentiate from sibling tools like sentinel_query_ledger, which could be a competing read/verification tool.

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?

The description implies this is a verification/audit tool to run when suspecting tampering, but provides no explicit when/when-not guidance or mention of alternatives. The context is reasonably clear for a read-only check tool, but there's no guidance on when to run this vs sentinel_query_ledger or other ledger-related tools.

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