Export Facility Metadata Table

export_facility_metadata_table

Exports reviewed facility metadata rows as a bounded ALE table while rejecting duplicate columns, unknown fields, and unsafe tabs/newlines; it does not read or change project metadata.

Instructions

Create a new bounded ALE facility metadata table from reviewed named field rows. Rejects duplicate columns, unknown row fields and tabs/newlines that ALE cannot safely represent. No project metadata is read or changed; verify downstream facility import separately.

Tool call template

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

Input Schema

Name	Required	Description
`fps`	Yes	Declared decimal frame rate up to 240; keep source rate provenance separately.
`rows`	Yes	Reviewed table rows containing only declared column names and bounded string values.
`columns`	Yes	Explicit unique column names.
`output_path`	Yes	Absolute caller-selected local file path. Referenced media is never opened automatically.
`idempotency_key`	No	Optional client-chosen key (1-128 chars of A-Z a-z 0-9 . _ : -) for this intended edit. Pass a fresh key per edit and reuse it only when retrying that same edit, for example after a client-side timeout. A repeat with the same tool, key and arguments is not run again: while the first call is running it fails with IDEMPOTENCY_IN_PROGRESS (poll get_last_operations); after it finished it returns the original outcome marked replayed. A definite failure with nothing applied (receipt outcome not_applied) may be retried with the same key. Reusing a key with different arguments fails with IDEMPOTENCY_KEY_REUSED. Scoped to this MCP session (the stdio server process, or the HTTP server process when Streamable HTTP is stateless per request) and held in memory only (200 keys, 1 hour); it does not survive a restart or reconnect. Read-only invocations are never deduplicated.
`expected_cep_target`	No	Optional reviewed CEP sequence/clip identity and exact tick ranges. Checked before every generated command; UXP refuses this CEP-only guard.
`expected_project_path`	No	Optional absolute saved-project path. Every generated CEP command refuses before its body when the active project differs or is unsaved. UXP commands refuse this CEP-only guard; local-only tools do not inspect Premiere. Omit to keep existing behavior.

Output Schema

Name	Required	Description
`ok`	Yes	Whether the tool completed successfully.
`data`	No	Tool-specific result data when ok is true; on failure, diagnostic detail when the tool provides it.
`tool`	Yes	The registered MCP tool name.
`error`	No	Failure detail when ok is false.
`receipt`	No	Versioned common mutation receipt; success never implies rendered verification.
`idempotency`	No	Present when idempotency_key deduplicated this call: replayed is true when the original outcome was returned instead of running again.

TDQS

A3.8/5.0

Behavior4/5

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

Annotations only declare the generic profile (readOnlyHint=false, destructiveHint=false, openWorldHint=false), so this is real added value: the description discloses validation behavior (duplicate columns, unknown row fields, tabs/newlines rejected) and a scoping guarantee that no project metadata is read or changed. It does not state what happens if output_path already exists, which is the main remaining behavioral blind spot for a file-writing tool.

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 sentences, front-loaded with the action and resource, followed by validation constraints, then the negative scope guarantee. Every sentence carries distinct information and nothing is padded.

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?

With an output schema present and a fully documented input schema, the description only needs to cover intent, constraints, and side effects, which it does. The remaining gap is file-level behavior at output_path (overwrite semantics, failure modes), which matters for a writer tool but is partly implied by the bounded-path parameter and the output schema.

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 the baseline is 3. The description's mention of rejected duplicate columns and unknown row fields largely restates what the schema already enforces via uniqueItems and row-value descriptions, adding little syntax or semantic detail beyond it. It says nothing about fps, output_path, or the idempotency/CEP guard parameters.

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 opens with a specific verb and resource: "Create a new bounded ALE facility metadata table from reviewed named field rows." That distinguishes it from read-oriented siblings like get_metadata and from the preview/plan siblings. It stops short of naming the closely related intake-preview tool, so differentiation requires the agent to already know what that sibling does.

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?

It establishes the input precondition ("reviewed named field rows") and a downstream caveat ("verify downstream facility import separately"), which implies this is a final write step after review. However, it never explicitly says when not to use it or routes the agent to `preview_facility_metadata_intake` for validating rows before export, leaving the choice of alternative to inference.

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