Repurpose one piece into several

The kit is good at making things. It has no answer for making more from what you already made — and for one person, that is the difference between three posts a week and twelve.

Not writing more. Getting more out of what is written.

The capability is already here: examples/ai-video-social/ holds the same Claude Fable 5 source as both an article and a video. Nothing connected "I made this once" to "make five more from it". This is that connection.

Before you start

Read the source properly. Not the title — the whole thing. A repurpose written from a headline produces five posts that all say the headline.

Then decide whether it deserves it. Repurposing a weak piece multiplies the weakness: five variants of something nobody engaged with is five times the work for the same silence. If the original is thin, say so and stop. The honest output here is sometimes "this one is not worth it — write something new instead".

Signals it is worth repurposing:

• it has a number, a result, or a claim someone could disagree with — those travel
• it took real work to research, so the value is already paid for
• it performed, or it covers something you know people ask about

1. Find the angles, do not invent them

An angle is a different thing the source says, not the same thing said differently. Rewording one idea five ways is spam; five ideas from one piece of research is a week of content.

Pull them from the source itself:

Four to six angles from a substantial piece. Fewer if the source is short — do not pad to hit a number.

2. Check what has already gone out

cat brain/repurposed.json   # { "<source-id>": { "angles": ["counterintuitive", "cost"], … } }

This file exists because history.json cannot answer the question. That is a flat list of published titles — it dedups by identity, so it knows the source went out but not which angle you used. Repurposing without this check is how the same point gets published three times in a month with different wording.

Skip angles already listed. If every angle is used, say so — that is a finished source, not a failure.

3. Produce, in the format that fits the angle

Match the container to the idea rather than making all five formats every time:

Vary the hook across variants. If all of them open with a number, they read as one post published five times.

Pairing with registry skills for multi-channel distribution:

• Multi-channel calendar: Use social-post-master to adapt tone, format, and spacing natively across Facebook, Instagram, Threads, and X.
• Hook & Copy refinement: Use marketing-core and fb-hook-extractor to test high-converting copy variants and distinct angle formulas.

4. Through the same gates as anything else

No shortcuts because the words already existed:

node scripts/social/validate-post.mjs brain/<slug>/repurposed/<angle>.json --strict

WRITING_CRAFT.md applies. review-gate applies. A repurposed post is a post.

5. Record what you used

Append to brain/repurposed.json:

{
  "rerank-rag-tieng-viet": {
    "sourceTitle": "Rerank trong RAG tiếng Việt",
    "angles": ["counterintuitive", "cost"],
    "lastRepurposedAt": "2026-08-03"
  }
}

Only record an angle after it publishes. Recording at draft time means a rejected draft burns the angle forever.

6. Report

Append to brain/<slug>/report.md: which angles were taken, which were left, and why any were rejected. The left-over list is what makes the next pass fast.

What not to do

• Do not republish the same angle in different words. That is what the state file is for.
• Do not repurpose across languages by translating. A translated post reads translated. Rewrite it for the new audience or skip it.
• Do not strip the source. A repurposed post that removes the number, the caveat and the link is a claim with nothing behind it. Keep what makes it checkable.
• Do not schedule them all for the same week. Spread them. The point is to fill weeks you would otherwise have nothing for.
