Audit log status and chain verification

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

With no annotations, the description carries the burden and does real work: it discloses that the log is process-local, resets on server restart, and that the call performs a full SHA-256 chain re-verification (a non-trivial whole-chain operation). It stops short of stating whether the re-verification is expensive, what a failed verification looks like, or any permission requirements, but the demo/non-durable nature of the data is clearly surfaced.

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, zero filler. The substantive payload (what is reported) comes first, and the caveats (process-local, resets on restart, demo of the production chain) follow as necessary qualification.

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, the description compensates by listing the returned fields, so an agent knows roughly what to expect. It does not describe the shape of the verification result (e.g., pass/fail flag versus first broken index), which is the one meaningful gap for a tool whose headline function is chain re-verification.

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 takes zero parameters, so there is nothing for the description to disambiguate. Baseline for a no-param tool 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 ('Report') and a specific resource (this server process's Sentinel audit log), then enumerates what is returned: entry count, genesis/tip hashes, and a full SHA-256 chain re-verification. This is unmistakable against siblings like sentinel_evaluate_action or sentinel_device_telemetry, which concern actions and devices rather than log state.

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?

Usage is only implied: an agent can infer this is the tool to call when it wants to inspect log state or check integrity. There is no explicit guidance on when to prefer it, no statement of prerequisites, and no mention of cost or when not to trigger a full re-verification.

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