Yesterday a small open source build landed on r/PromptEngineering, and it goes after a problem almost everyone has. You save a reel because it looks useful. You never open it again. Three years later the folder is a graveyard, and the only thing it teaches you is how good you are at hitting the bookmark button.
What’s new
u/OldAdministration463 shared doomer-agent, an open source skill for Claude and Codex. It looks back through your saved reels and turns the useful bits into reusable SKILL.md instructions. The repo is here: https://github.com/jnh12/doomer-agent
Think about how many reels you have saved right now. Cooking tricks, prompt formats, editing shortcuts, automation ideas, a workout you swore you would try on Monday. Each one had a real idea inside it. The problem was never finding good stuff. The problem was that nothing ever happened after the save. This build is aimed squarely at that gap.
The twist
The output isn’t a summary or a pile of notes. It’s a SKILL.md, the same file format your agent already knows how to load and follow.
So a reel you saved and forgot can become an instruction your agent actually uses. One commenter put it this way: their saved folder is “a graveyard of ‘i’ll get to this later’ posts stretching back 3 years,” and turning that into structured instructions instead of more saved posts is what made it click for them.
Here is a concrete picture. Say you saved a reel about a better way to structure prompts for product descriptions: role first, then constraints, then a short example, then the output format. Normally that sits in your saved tab forever. With this approach it can become a skill your agent loads whenever you ask for product copy, so the technique gets applied without you rewatching a 40 second video and trying to remember the order.
That’s the leverage. Saving is passive. A skill is something that runs.
Mini-workflow (how I’d try it)
I haven’t dug through the repo internals, so check the README for the exact setup. The general shape looks like this:
- 📥 Clone the repo and drop the skill into your Claude or Codex skills setup. Keep it in a folder you can find later, because you will want to tweak it.
- 📱 Point it at your saved reels. If you can, start with one collection or topic, like only your AI and automation saves, so the results stay focused.
- 🧠 Let the agent pull out the parts worth keeping: the actual techniques, not the hype. A good skill has steps, inputs, and a clear trigger for when to use it. A bad one is a vibe with a title.
- 📝 Review the SKILL.md files it generates. Check the name, the description, and the steps. The description matters most, since that is what tells your agent when to reach for the skill.
- 🔁 Keep the ones you’d really use. Delete the rest.
Pro tips
- Treat the generated skills as drafts. A reel can be wrong, outdated, or just a vibe. Read each SKILL.md before you let your agent trust it.
- Start small. Run it on a handful of saves first and see whether the output is useful before you feed it years of backlog. Five good skills beat fifty mediocre ones.
- Keep skills narrow. One skill, one job. If a generated file tries to cover five things, split it.
- Test each kept skill once on a real task. Ask your agent to do the thing and see whether it follows the steps. If it ignores the skill, the description probably needs a clearer trigger.
- Watch for duplicates. Creators love to repeat the same tip in slightly different words, so you may end up with three skills that say the same thing. Merge them into one good version.
Why this one is worth a look
Most “second brain” tools stop at storage. This one goes after the step people skip, which is turning what you saved into something you can use. It’s a young project with a small amount of attention so far, so expect rough edges. It’s also open source, so you can read it, fork it, and bend it to your own setup.
If your saved tab is a graveyard, this might be the shovel. ⛏
Call to action
Go check out the repo, try it on a few saves, and tell the author what worked and what didn’t. Early feedback is what helps a small open source project grow. ☠
