Delete Project

delete_project
DestructiveIdempotent

Permanently delete a project you created (cleanup). Removes its composition and render history. Irreversible — only call on a project you own and no longer need.

Tool call template

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

    "arguments": {
      "projectId": "<projectId>"
    },
    "name": "delete_project"

commandIdNoRetry identity. A call repeated with the same commandId returns the first result instead of acting twice.

TDQS

A4.2/5.0
Behavior4/5

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

Annotations already declare destructiveHint=true and idempotentHint=true, so the lower bar applies; the description still adds the cascade targets (composition plus render history) and the ownership requirement, neither of which is in the annotations. It does not say whether active renders or jobs block deletion, which is the main remaining gap.

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?

Three short sentences, front-loaded with the irreversible action and cascade scope before the safety caveat. No filler, and the destructive nature is stated immediately.

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

Completeness4/5

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

For a destructive two-parameter tool with strong annotations and full schema coverage, the description supplies the cascade semantics and ownership precondition an agent needs before acting. Missing only the interaction with in-flight work (active renders or jobs) and whether deletion is blocked or forced.

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% and commandId is documented as retry identity, so the schema carries the parameter burden. The description adds nothing about projectId format or how to obtain it, leaving this at baseline.

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?

States a specific verb+resource ('Permanently delete a project') with the cascade scope spelled out ('Removes its composition and render history'), which distinguishes it from sibling deleters such as delete_composition and delete_brief. The parenthetical '(cleanup)' further signals intent.

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?

Gives an explicit precondition and gating condition: 'only call on a project you own and no longer need,' which prevents casual or speculative deletion. It stops short of naming a sibling alternative (e.g., update_project, or deleting only a composition), so it is clear context without full routing.

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