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

With no annotations, the description carries the full behavioral burden and does so substantively: it states idempotency, statelessness, replay admission, identical receipt_hash, and timeout-retry safety. It leaves the side effects of `annihilate raw context` unspecified, but this is still strong behavioral disclosure compared to typical descriptions.

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 compact, front-loads the pipeline, and devotes only two additional sentences to idempotency and retry semantics. A plain-language summary would help, but as written every sentence earns its place and there is no padding.

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 schema and referenced signing algorithm are rich, and the description explains idempotent retry well. However, there is no output schema and the description only mentions `receipt_hash` without defining the full return contract. For a complex 8-parameter protocol with 14 intent values and an undefined `bond_status`, the context remains incomplete.

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 free-text description adds no parameter-level meaning, but the input schema already documents 6 of 8 parameters, including a very detailed `client_signature`. The under-documented `intent` (enum-only) and `bond_status` are not compensated for, so the description stays at a baseline-3 level without improving parameter understanding.

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 names a concrete membrane pipeline (`Rational S4/C4 lanes -> SCF boundary -> annihilate raw context -> NATS geometry-only turn -> Aristotelian projection`) but never explains in plain terms what a transition is or what observable result it produces. It avoids being a tautology, yet an agent without domain vocabulary cannot reliably tell what this tool accomplishes, and it does not contrast itself with sibling `execute_*` tools.

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 gives one actionable retry rule (`Safe to retry on a timeout; it is not a second transition`) and clarifies idempotent replay behavior. However, it never states when to choose this tool over alternatives or what input conditions warrant calling it, so the primary usage guidance is only implied.

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