Select a saved take without altering its file's prompt

native.genads_select_take
DestructiveIdempotent

Select a saved take without altering its file's prompt. Adds the generated asset to Sources for explicit rights and claim review before creative release.

Input Schema

NameRequiredDescriptionDefault
work_idYes
argumentsYes
read_skillsYesExact required native skills and their dependencies, copied from the accepted session bootstrap's skills array. Include only entries in that array. General mcp.* guides and native.{studio}.instructions are guidance, not native skill proofs.
request_keyYes
publication_proposal_idNoFor native Social scheduling, the exact server-approved publication proposal. This identifier cannot confer approval by itself.
expected_catalog_versionYesFor a new session, read a studios/{studio}/native/{pack} child toolset and copy invocation.catalog_version from a native tool descriptor. Do not use the top-level library version. For calls in an existing session, use that session proposal's catalog_version.

B3.1/5.0
Behavior3/5

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

The annotations already declare destructiveHint=true, idempotentHint=true, openWorldHint=true and readOnlyHint=false, so the safety profile is covered structurally. The description still adds real value by naming the side effect ("Adds the generated asset to Sources") and by scoping the mutation (the file's prompt is left untouched), but it omits the required native-skill proof, catalog-version freshness, and revision-conflict behavior that gate a successful call.

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?

Two tight sentences with no filler; the non-destructive scoping constraint is front-loaded and the side effect follows. Nothing is redundant, though the second sentence drifts into governance language ("explicit rights and claim review") rather than operational detail.

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?

For a 6-parameter tool with a nested required object, a 50% description coverage, and skill/catalog-version prerequisites, the description is under-specified — an agent still cannot tell which take to select or how to satisfy read_skills and expected_catalog_version. An output schema exists, so return values need not be explained, but invocation prerequisites are a substantial omission.

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 50%, and the description contributes nothing about parameters — it names no take_id, media_id, expected_revision, request_key, or work_id semantics. The nested required object's fields are entirely undocumented, so the description fails to compensate where the schema is silent, which is a bigger gap than the baseline-3 case.

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 gives a specific verb plus resource ("Select a saved take") and a scoping qualifier ("without altering its file's prompt"), which is clearly actionable. However, it never distinguishes this from closely named siblings such as native.select_film_saved_take, native.select_element_take, or select_workshop_take, so an agent cannot route between them from the description alone.

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

Usage Guidelines3/5

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

Usage is only implied through the phrase "before creative release" and the mention of rights and claim review, which hints at the workflow stage where this belongs. There is no explicit when-not guidance and no named alternative (e.g. inspect_take vs. takes vs. recover_take) for the agent to fall back on.

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