macro_file_reservation_cycle

Reserve file paths for a coding agent to prevent concurrent edit conflicts, with optional automatic release at the end of a workflow.

Instructions

Reserve a set of file paths and optionally release them at the end of the workflow.

Behavior2/5

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

No annotations are provided, so the description carries the full behavioral burden and largely fails. It does not disclose locking exclusivity, TTL/expiry behavior, auto-release semantics, conflict handling, or the need for a registration token — all of which are critical for a mutation tool that reserves shared resources.

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

Conciseness3/5

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

The single sentence is front-loaded and waste-free, but for a 9-parameter macro it is under-specified rather than genuinely concise, leaving the agent without the operational detail it needs.

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

Completeness2/5

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

An output schema exists, so return values need not be explained. But with no annotations, 0% parameter coverage, and a mutation that reserves shared resources, the description is far too thin to let an agent call the tool correctly.

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

Parameters2/5

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

Schema description coverage is 0% across 9 parameters, so the description must compensate but only gestures at 'paths' and 'release'. Critical parameters like exclusive (default true), ttl_seconds, auto_release, and registration_token receive no explanation in either the schema or the description.

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 verb (reserve) and resource (file paths) and adds the cycle concept ('optionally release them at the end of the workflow'), so an agent can grasp the purpose. However, it never distinguishes this macro from the closely related siblings file_reservation_paths and release_file_reservations, which is the differentiator a 5 would require.

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

Usage Guidelines2/5

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

There is no explicit when-to-use guidance and no comparison against alternatives. The phrase 'end of the workflow' faintly implies this is a combined reserve-then-release macro, but the agent is left to infer whether to call this or the individual reservation/release tools.

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