Trial Reels skill

Give your agent one reel. It renders five test versions with different hooks and looks, then posts them through tinyposter.

The honest deal

Rendering all five reels is free. Your first post is free, no card. Scheduling the other four needs a paid plan, from 9 dollars a month. See pricing.

What the skill does

Trial Reels is a skill for Claude Code and Codex. You hand your agent one reel video. It makes five slightly different versions and posts them, so you can see which hook actually wins. Here is the whole flow, start to finish:

  1. You give your agent one reel video.
  2. It checks Node is installed. It needs version 20 or newer.
  3. It installs the render tools. This happens once.
  4. It finds the talking parts of your video.
  5. It makes a plan for five versions: flipped, trimmed, re-timed, new text on screen, new captions.
  6. You approve the words before it renders anything.
  7. It renders the 5 reels. This takes 5 to 15 minutes.
  8. It shows you a check frame from each reel so you can look before anything posts.
  9. It connects tinyposter. A browser window opens. You click Allow.
  10. It posts reel 1 to Instagram. Your first post is free.
  11. It offers to schedule reels 2 to 5. Scheduling needs a paid plan.
  12. It gives you a recap: what went out, what is scheduled, and when.

Install with Claude Code

You do not need to know code. You copy one message and paste it.

    Set up the Tinyposter Trial Reels skill for me.

1. Check Node: run "node --version". I need version 20 or newer. If it is
   missing or old, help me install it from https://nodejs.org (pick LTS),
   then keep going.
2. Run: npx tinyposter-reels@latest --yes
3. If anything fails, read the error, fix it, and run step 2 again.
4. Check the "tinyposter" MCP server is connected. In Claude Code, check
   /mcp. In Codex, run "codex mcp list" and "codex mcp login tinyposter"
   if it needs a login.
5. Tell me it worked, then ask me for the video I want to turn into
   trial reels.

    Paste it into Claude Code and press Enter

    Claude sets everything up. It may ask to run things. Say yes. When the tinyposter login opens in your browser, click Allow.

    No Claude Code yet? It is Anthropic's AI helper for your computer. It needs a paid Claude plan. Get it at claude.com/claude-code, then come back.

    Check it worked

    Run /mcp inside Claude Code. You should see tinyposter in the list. Then tell Claude:

    text
    Make trial reels from my video.

Install with Codex

Same message, same steps. Paste it into Codex and press Enter.

If the browser window does not open
Run codex mcp login tinyposter in your terminal. It opens the tinyposter login so you can click Allow. Then run codex mcp list to confirm tinyposter is connected.

Other ways to install

Run the installer yourself. One command in your terminal:

bash
npx tinyposter-reels@latest

Manual. Download the skills/trial-reels folder from GitHub and put it in ~/.claude/skills/ (Claude Code) or ~/.agents/skills/ (Codex).

Where it lands. The installer copies the skill to ~/.claude/skills/trial-reels (Claude Code) and ~/.agents/skills/trial-reels (Codex). To remove it later: npx tinyposter-reels --uninstall.

Troubleshooting

▸It says Node is missing or too old

Install Node from nodejs.org. Pick the LTS version. Then paste the setup message again.

▸The first render is slow

The first render downloads a small browser that draws the text and captions. It needs internet for that one download. After the first time, renders are faster.

▸Instagram said I hit a trial reel limit

Instagram caps how many trial reels you can post per day. Wait until tomorrow, or ask your agent to post it as a normal reel instead.

▸My video is over 50 MB

Keep reels under about 50 MB. 1080p is plenty. Export a smaller file or compress the video, then try again.

▸Scheduling says I need to upgrade

The free plan includes 1 post, so reel 1 goes out free. Scheduling reels 2 to 5 needs a paid plan, from 9 dollars a month. Upgrade from billing.

▸How do I update the skill?

Paste the setup message again. The installer always grabs the newest version.

▸How do I uninstall?

Tell your agent: run npx tinyposter-reels --uninstall. It removes the skill folder and leaves your tinyposter account alone.
