Adds a line chart beside a person talking to camera that draws itself left to right and ends on the latest value, labelled: growth, a fall or a trend. Timed to the words they say, on their own footage, with their sound kept; 16:9, 9:16, 1:1 or 4:5. Renders locally with Chrome and ffmpeg: no video model, no key and no cost. Use when someone describes a trend over time and wants it drawn as they speak.

About this skill

You say

In talk.mp4 draw the weekly meeting hours falling over one quarter.

It said back

I've added the falling line to talk.mp4 and rendered it as talk-graphics.mp4 in the working folder (1920x1080, 24.3 s, 30 fps). The speaker's sound is unchanged.

  • Timing: the beat starts at 17.4 s on "After one quarter, meeting time dropped by 40%". The line draws in about 1.5 s and stays until "old Monday call", about 24.2 s.
  • Layout: the speaker slides to the right half and the chart fills the left half. The title is "Weekly meeting hours", the axis runs from "Start" to "1 quarter", and the line ends on a dot labelled "-40%".
  • Look: paper, with the face position set to [49, 30] from the face-check frame. The check found no layout problems.
  • Line shape: she gave only two figures, 12 hours a week at the start and a 40% drop after one quarter, so the in-between points are my own. The line runs 12 → 9.8 → 8.4 → 7.6 → 7.3 → 7.2 and levels off at the end, so the "-40%" label doesn't sit on the line. It is a drawn shape, not data from the talk.
  • Derived 12 → 7.2: the start of 12 comes from her "12 people, 1 hour, every Monday". The end of 7.2 is 40% below that. Neither number is spoken as an hour figure, and the chart doesn't print them.

Questions

Is Trend Line free?

No. Trend Line costs $9.99 once and stays in your Recaply account, or it comes with the Recaply plan ($19.99 a month), which opens every premium skill and prompt.

Which agents can use Trend Line?

Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot and OpenCode.

What do I get when I buy Trend Line?

A ZIP of the whole skill folder (105 KB): the SKILL.md your agent follows and its 12 other files, the references, templates and scripts it uses. You download it from this page whenever you need it, and install it in Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot and OpenCode. The Recaply plan opens it too, with every other premium skill and prompt.

How do I install Trend Line?

Buy it, then download the ZIP from this page. For Claude Code, unzip it into .claude/skills/ in your project. For Codex, Cursor and Gemini CLI, unzip it and run npx skills add ./trend-line-overlay with your agent's flag.

What do I get from Trend Line?

Your video with the overlay timed to the words, sound kept. The line draws across the chart as they talk, then a dot and a label land on the last value. 16:9, 9:16, 1:1 or 4:5.

What does Trend Line need?

Node 22+, Chrome and ffmpeg, and no API key. Each use costs nothing beyond your agent.

How big is Trend Line?

13 files, about 79,930 tokens in all. The SKILL.md is about 2,267 tokens, and your agent reads it only when the job fits.

What does a run cost?

Our 1 runs took 1 min 57 s to 1 min 57 s and $0.21 to $0.21 of API use each, in Claude Code with claude-sonnet-5-5. On a Claude plan, a run counts toward your usage instead.

Do I have to name Trend Line to use it?

Type /trend-line-overlay first to make sure it loads. Without it, Claude Code may judge a small job simple enough to do without the skill.
