How we verify

Evidence: Screenshots or logsThe source shows screenshots, a transcript or the agent's output.

PartialThe source says it only partly worked, or had a significant problem a person had to deal with.

What went wrong: Great at analysis, but its own clip cuts were unusable (no context or conclusion) even after several prompts.

Outcome

Given brand context, timestamped transcripts, example clips and performance data, Claude Cowork analyzed the content well and surfaced topics and hooks, saving hours of watching; but the clips it cut started mid-thought or lacked context or conclusions, even after several re-prompts.

Prompt Improved prompt

Strengthened by us to avoid the problem in the source. Not tested by the poster. It doesn't change what happened in the source.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Use my video transcripts to find the best short-clip moments, so I can cut them myself.

Quick-check questions: Which channel or videos, how long should clips be, and what's worked before?

What I'll give you:
- Timestamped transcripts ([FILES])
- 2–3 example clips I liked
- Performance data, if I have it
- Clip length (e.g. 20–30 seconds)

Rules:
- Analyze only; don't cut or export video files.
- For each suggested moment, give start and end timestamps that begin at the start of a thought and end at its conclusion.
- Quote the opening and closing line so I can check it makes sense on its own.
- Rank by fit with what has performed before.

Output: A ranked list of moments: video, timestamps, opening/closing lines, why it works.

If my answers leave a gap, make a sensible choice, say what you assumed, and keep going.

You'll know it worked when: I can jump to each moment and it stands alone without extra context.

This prompt has blanks to fill in, like [FILES]. We'll copy it instead of filling it in, so you can edit it before you send.

The prompt they actually used (our rebuild)

The source didn't share its exact prompt, so we wrote this from what it describes.

Here's the brand context, timestamped transcripts, examples of clips I picked and our performance data. Find 20–30 second moments worth repurposing and make the clips.
Optional stronger version

Our rewrite with extra checks. The poster didn't test it.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Use my video transcripts to find the best short-clip moments, with timestamps precise enough that I can cut them myself.

Questions to ask me first:
- Which channel or videos, and how far back?
- How long should clips be, and for which platform?
- Which past clips worked best for you?

Inputs (fill in or confirm):
- Timestamped transcripts ([FILES])
- 2–3 example clips I liked and why
- Performance data, if any
- Target clip length and platform

Rules:
- For each moment give start and end timestamps that include the setup line and the payoff or conclusion, not just the punchline.
- Write one line on why it works as a standalone clip (hook, tension, clear takeaway).
- Rank moments using patterns from my example clips and performance data.
- Don't cut or export video yourself; give me cut points only.
- Mark moments that need on-screen context (a chart, a demo) to make sense.

What went wrong before, and how to avoid it:
- Last time its own clip cuts had no context or conclusion: include setup and payoff in every cut, and leave the cutting to me.

If you get stuck: If a moment only works with earlier context, either extend the start time or drop it; say which. If a login, CAPTCHA or two-step code appears, stop and ask me to handle it; never guess or store passwords.

Verify before you finish: Re-read each moment from start to end timestamp and confirm it makes sense with no outside context.

Output: A ranked table: video, start, end, length, hook line, closing line, why it works.

Done when: each listed clip makes sense on its own when cut exactly at the given times.
