reserve_file

Reserve a file ID to embed in the filename before writing code, enabling consistent tracking across the reserve-write-finalize flow.

Instructions

Reserve a file ID before writing code — part of the mandatory reserve-write-finalize tracking flow. Returns ID to embed in filename.

Tool call template

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

TDQS

A4.3/5.0
Behavior4/5

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

Annotations indicate readOnlyHint=false, destructiveHint=false, idempotentHint=false. The description adds behavioral context by noting it's a mandatory step that returns an ID to embed. No contradiction with annotations, and it clarifies the role in a multi-step process beyond what annotations provide.

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

Conciseness5/5

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

Two concise sentences, front-loaded with the core action. Every word adds value: verb, resource, flow context, and return value. No fluff.

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

Completeness5/5

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

Given no output schema, the description explicitly mentions the return value (ID). Parameter coverage is full. The description explains the tool's role in a higher-level workflow, making it complete for an agent to understand when and how to invoke it.

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

Parameters3/5

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

Schema description coverage is 100%, so each parameter is already documented. The description adds general context ('Returns ID to embed') but does not enhance individual parameter understanding beyond the schema. Baseline 3 is appropriate.

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

Purpose5/5

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

The description clearly states the verb 'Reserve' and the resource 'file ID', and situates it within the 'mandatory reserve-write-finalize tracking flow'. It distinguishes itself from siblings like 'reserve_files' (plural) and 'finalize_file', making the purpose unambiguous.

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 description explicitly says 'before writing code' and 'part of the mandatory ... flow', providing clear when-to-use context. It doesn't explicitly state when not to use it or name alternatives, but the flow context is sufficient for guidance.

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