verify_chain_integrity

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

With no annotations, the description carries the full burden. It discloses that the tool walks and verifies chains, refuses mixed-schema chains, and returns a specific structure ({valid, checked, broken_at, reason}). This provides good insight into behavior, though it doesn't mention side effects or permissions.

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 short (two sentences) but includes the unclear 'Capability 8' prefix. It conveys the main action and return format, but could be better structured and avoid jargon.

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 tool has one optional parameter and an output schema, the description mentions return fields but does not explain them in detail. It covers basic functionality but lacks completeness on error conditions or parameter behavior.

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 schema has only one parameter (trace_id, nullable with default null). The description mentions 'trace_id' in context but does not explain the implications of null or the format. With 0% schema coverage, the description adds limited meaning beyond the schema.

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 clearly states the tool's purpose: to walk and verify every link in a persisted envelope chain for a given trace_id. It also mentions that it refuses mixed-schema chains, distinguishing it from sibling tools like verify_tool_descriptor.

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 does not provide any guidance on when to use this tool versus alternatives. It mentions 'Capability 8' which is not helpful, and there are no when-to-use or when-not-to-use instructions.

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