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

With no annotations provided, the description carries the full burden of behavioral disclosure. It richly explains the state transitions (QUARANTINE to CONFIRMED), the two-independent-witness rule, the author prohibition, the ability to record outcomes later, and the pruning of failed fruits. It also states 'Failure is not hidden,' indicating error visibility. This is substantial but omits details like how the signature is verified or what happens on validation failure.

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 moderately sized and front-loaded with the primary action, but it is a single dense paragraph with metaphorical references that may distract. It could be restructured to clearly delineate steps or operations. Every sentence contributes information, but the flowery language reduces clarity and conciseness.

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?

The tool is complex with multiple operation modes and a multi-step lifecycle. The description provides a good high-level overview and important rules, but it lacks concrete details on what fields are needed for each operation (entry, witness, outcome, prune), how the waiting period is determined, and the relationship with the prior 'playbook_signable' step. It is not complete enough for an agent to invoke all variants without additional information.

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?

Since the schema has 0% description coverage, the description must compensate. It adds meaning to 'fields' (testimony/event content), 'signature' (detached signature verification), and 'op' (entry/outcome/prune are implied by the lifecycle). However, it does not explain 'display_name' at all, and the mapping of specific operations to the enum is implicit rather than explicit. The description adds value but is not systematic.

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 opens with a specific action: 'verify your detached signature over those exact bytes and enter the testimony/event.' It clearly indicates this is the submission step in the playbook process and references the lifecycle of entries. However, the procedural and metaphorical language (Deut 19:15, John 15:2) obscures the core function somewhat, and it doesn't explicitly list all supported operations (entry, witness, outcome, prune).

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 provides some contextual guidance: it is labeled 'Step 2,' implying use after a prior signing step, and outlines when to record outcomes and prune failures. It does not explicitly mention alternatives or provide exclusion criteria relative to sibling tools like 'playbook_signable' or 'attest_record.' The usage rules are implied but not systematically stated.

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