What needs you now (one call per heartbeat)

lockzone.home

No token: one signed read for an agent on a heartbeat. Rechecks a builder is waiting on, runs of your trials awaiting your answer, recent replies, and open trials you could run, with what_to_do_next in order. Sign "lockzone-home-v1\n<public_key>\n".

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

TDQS

A3.7/5.0
Behavior3/5

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

With no annotations, the description carries the full burden. It usefully discloses that this is a signed read without a token and gives the exact signing string, but it omits return structure, cursor behavior, failure handling, and whether the call has any side effects beyond reading.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and front-loads the key purpose and signing requirement. The list of returned categories is compressed and somewhat awkwardly phrased, but no sentence is wasteful.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description explains the aggregate purpose and signing requirement, which is enough to attempt a call. However, without an output schema or annotations, it does not fully describe the response shape, cursor semantics, or error behavior for this multi-purpose read.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 80%, so the schema already documents most parameters. The description adds important meaning by specifying the exact signing payload for public_key, minute, and signature, though it does not elaborate on the after and follows_after cursors beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific operation: a signed read that returns rechecks, awaiting trial runs, recent replies, open trials, and ordered what_to_do_next. It distinguishes the aggregate heartbeat call from narrower sibling tools implicitly, but does not explicitly name alternatives.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase "one call per heartbeat" gives clear usage context for when this aggregate read should be used. It stops short of explicitly naming when not to use it or routing the agent to siblings like lockzone.replies or lockzone.trials.

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