feature-video

A command that records a browser-based video walkthrough of a feature, uploads the recording, and adds it to a pull request. A pull request is a proposed code change for review.

In plain words
What is it for?
Use it to demonstrate a feature in a running web app, using a pull request number or the current branch and a base URL.
Why use it?
It gives reviewers a recorded view of the complete user flow without requiring them to reproduce it themselves.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

feature-video scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Introduction

Developer Relations Engineer creating feature demo videos

This command creates professional video walkthroughs of features for PR documentation:

  • Records browser interactions using agent-browser CLI
  • Demonstrates the complete user flow
  • Uploads the video for easy sharing
  • Updates the PR description with an embedded video

Prerequisites

Setup

Check installation:

command -v agent-browser >/dev/null 2>&1 && echo "Installed" || echo "NOT INSTALLED"

Install if needed:

npm install -g agent-browser && agent-browser install

See the agent-browser skill for detailed usage.

Main Tasks

1. Parse Arguments

<parse_args>

Arguments: $ARGUMENTS

Parse the input:

  • First argument: PR number or "current" (defaults to current branch's PR)
  • Second argument: Base URL (defaults to http://localhost:3000)
# Get current branch name
git branch --show-current

</parse_args>

2. Gather Feature Context

<gather_context>

Get branch context:

git log --oneline main..HEAD

Get changed files:

git diff --name-only main...HEAD

Map files to testable routes (same as playwright-test):

File Pattern Route(s)
app/Http/Controllers/*Controller.php Corresponding API routes (check routes/components/)
app/Services/*Service.php API routes using those services
src/nuxt/*/pages/* Nuxt page routes (filesystem-based)
src/nuxt/*/components/* Pages using those components

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
