Clip processing status

clip_processing_status

Read-only

Report whether a clip — or every video clip in the project, if clip is omitted — has been through the browser-side video-processing pipeline: proxy build, audio split, transcription, OCR (text regions). Processing never runs on the server. The preview proxy is mandatory: every processing run builds it, and the Morpha editor builds any missing proxy for every page's clip when the project is opened. The other steps run in the editor too. Returns { ok: true, data: { clips: [{ clip, processed, steps: { proxy, audio_split, transcript, text_regions } }], allProcessed } }, where each step is 'ready' | 'pending' | 'running' | 'unavailable' | 'cancelled' | 'error'. 'cancelled' is a transcript the user stopped in the editor: it stays stopped across opens, and only the editor's Re-run starts it again. audio_split stays 'pending' until the user splits the clip's audio into its own track in the editor (Inspector → Audio → Split audio); it never gates processed, and an unsplit clip plays its own sound. Use it to know whether transcribe_clip / detect_text_regions will return data, and to surface an 'unprocessed' state to the user.

A4.4/5.0

Behavior5/5

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

Goes well beyond the readOnly/non-destructive annotations by disclosing that processing never runs on the server, that the preview proxy is mandatory and auto-built by the editor on project open, the 'cancelled' transcript persistence behavior, and that audio_split never gates `processed`. These are non-obvious behavioral traits an agent cannot infer from annotations.

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?

Purpose and usage are front-loaded effectively, but the long prose walkthrough of the return object and its enum values is largely redundant given an output schema exists. The 'cancelled'/'audio_split' notes earn their place; the inline response shape does not.

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?

Covers the full behavioral picture for a read-only status probe and explains the step-state semantics thoroughly. It is more complete than needed since the return format is duplicated from the output schema, but nothing an agent needs is missing.

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 schema already documents both parameters including the 'omit clip to report every video clip' semantics. The description restates that omission behavior rather than adding syntax or format detail beyond the schema, so the baseline 3 applies.

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 (report) and resource (clip processing status), and enumerates exactly what the pipeline covers: proxy build, audio split, transcription, OCR. An agent can immediately distinguish this read-only status probe from the mutation siblings like transcribe_clip or detect_text_regions.

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

Usage Guidelines5/5

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

Explicitly names the downstream alternatives it gates: 'Use it to know whether transcribe_clip / detect_text_regions will return data.' It also states the precondition that processing is browser-side, not server-side, so the agent knows this is the only way to learn the state.

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