architect_task_claim

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

Annotations already declare a mutating (readOnlyHint=false), non-idempotent, non-destructive operation, so the description need not repeat that. It does add real context: only "ready" tasks can be claimed and the call acquires a private attempt lease, implying ownership semantics. However, it omits what happens on contention, lease expiry, or whether a failed claim is an error.

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?

A single front-loaded sentence with no waste, which is good, but it is terse to the point of under-specification given the coordination semantics involved. Efficiency here comes partly at the expense of completeness.

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?

This is a state-mutating coordination tool with no output schema and no description of return values (lease handle? attempt ID?), lease duration, or failure modes. Combined with undocumented run_id and a dense sibling set, the definition leaves too much for an agent to guess.

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?

Schema coverage is only 33%: workspace is documented in-schema, but run_id and task_id have no descriptions anywhere. The description's mention of "task" weakly maps to task_id but gives no format, and run_id is completely unaddressed, so the description fails to compensate for the coverage gap.

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?

Specific verb "claim" plus two concrete resources (core task and private attempt lease). It distinguishes the tool reasonably from siblings like architect_task_heartbeat or architect_task_complete, though domain terms "ready core task" and "attempt lease" are never defined.

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?

No statement of when to call this versus alternatives such as architect_runtime_next or architect_task_heartbeat, and no mention of preconditions beyond the word "ready." The agent must infer the claim/execute/heartbeat workflow entirely from sibling names.

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