What it does
Post every peepshow run into a Slack channel as a formatted Block Kit message. Includes video title (from container metadata), extraction summary, and a thumbnail of the first key frame.
When to reach for it
- Notify a #ai channel whenever an agent processes a new demo video
- Flag long videos that took unusually many frames to summarise
- Push bug-report videos into a #triage channel with the frames pre-attached
Install
npm i -g peepshowUse it
peepshow ./bug.mov --sink slack \
--sink-arg webhook=https://hooks.slack.com/services/...Make it automatic
Register the sink once — every run fires it afterward. Scope by --when so it only runs for matching videos.

peepshow sinks add slack --when extension=mp4,mov
peepshow sinks add slack --when path=/Volumes/Work/Configuration
PEEPSHOW_SLACK_WEBHOOKIncoming-webhook URL for the target channel. requiredPEEPSHOW_SLACK_USERNAMEOverride the bot's display name.
Use with an LLM agent
Every peepshow sink reads its config from env vars and receives a single JSON payload on stdin. An LLM agent (Claude Code, Cursor, Windsurf, Gemini, Codex) can drive the Slack sink automatically when three things are true:
- the env vars below are exported in the agent's shell (or a project
.envit can load), - the
peepshowCLI is onPATH— install withnpm i -g peepshow, - a peepshow auto-sink is registered for the run (optional but recommended — makes invocation zero-argument).
1. Set the environment
# Add to ~/.zshrc, ~/.bashrc, or a project .env the agent can load
export PEEPSHOW_SLACK_WEBHOOK="..."2. Register as an auto-sink

/peepshow:slides ./clip.mov. peepshow extracts frames + audio, theSlacksink forwards the run to the configured channel. Claude replies with a summary and a link to the created record.
The transcript snippet is posted alongside the frames as a secondary message.
Write your own
A sink is any executable that reads the --emit json payload on stdin. Shell, Node, Python, Go — the spec's in docs/PLUGINS.md. Register persistent ones with peepshow sinks add-cmd 'your-command'.
