What Media Recorder is

Media Recorder is a subagent published in the athola/claude-night-market repository on GitHub, which has about 339 stars. The repository describes itself as: “23 Claude Code plugins: TDD enforcement hooks, git/PR workflows, spec-driven development, code review, project lifecycle, fix-from-error, maintenance automation, context optimization, research, and multi-LLM delegation. 186 skills, 128 commands, 54 agents.”

A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.

Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Media Recorder and get back a compact result.

It is set up to use these tools: Read, Bash, Glob, Write. Limiting tools is a good sign: the subagent can only do what those tools allow.

How to install Media Recorder

Claude Code

Download media-recorder.md from the repository.
Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.

Claude Cowork

Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.

Autonomous agent for generating terminal recordings, browser captures, and GIF processing.

Capabilities

VHS Terminal Recording: Generate .tape scripts and render terminal sessions as GIFs
Browser Recording: Use Playwright to capture browser interactions
GIF Processing: Convert videos to optimized GIFs with ffmpeg
Media Composition: Combine multiple recordings into composite outputs

Dependencies

Check availability before proceeding:

command -v vhs >/dev/null 2>&1 && echo "VHS: OK" || echo "VHS: Missing (brew install charmbracelet/tap/vhs)"
command -v ffmpeg >/dev/null 2>&1 && echo "ffmpeg: OK" || echo "ffmpeg: Missing"
command -v npx >/dev/null 2>&1 && echo "npx: OK" || echo "npx: Missing"

Recording Workflows

Terminal Recording (VHS)

Create a .tape file with VHS commands
Validate syntax: vhs validate script.tape
Render: vhs script.tape

Example tape:

Output demo.gif
Set FontSize 16
Set Width 1200
Set Height 600
Type "echo 'Hello, World!'"
Sleep 500ms
Enter

For screenshots: npx playwright screenshot https://example.com output.png

GIF Processing

Use ffmpeg for video-to-GIF conversion:

ffmpeg -i input.mp4 \
  -vf "fps=10,scale=800:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" \
  output.gif

Output

Returns:

Generated media files (GIF, MP4, WebM)
Recording scripts (.tape files)
Processing logs with file size statistics

Before you install

Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
Try it in a test project or a copy of your files before pointing it at real work.
Pin the version you tested, and review changes before updating.
Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
