Summarizer skill for OpenClaw
What this skill does
Summarizes any source without losing the claim: documents, meetings, papers, threads, transcripts, data, and code changes. Use when asked to summarize, condense, shorten, recap, distill, or write a TLDR, abstract, or executive summary; when a source is too long to read or must hit a word count; when summarizing a call, interview, Slack channel, pull request, contract, earnings report, podcast, or a stack of sources on one topic; when a summary dropped something important, invented a detail, turned a hedge into a fact, or reads like the headings; and when the same material must be re-cut for another audience, length, or channel. Covers compression ratios, chunking, faithfulness and omission audits. Not for recurring external feeds (`digest`), decision documents whose point is the recommendation (`brief`), cross-source insight generation rather than compression (`synthesize`), or pulling text or a transcript out of a file or video first (`extract-pdf-text`, `youtube-video-transcript`).
The Summarizer skill is part of the Developer Tools category — developer tools that help your agent write, review, debug, and ship code. You can install it on its own or alongside other developer tools skills from the OpenClaw catalog.
How to install the Summarizer skill
The easiest path is via the OpenClaw Easy desktop app — one click, no terminal required:
- Download OpenClaw Easy for macOS or Windows (free, one-click installer, ~30 seconds).
- Open the in-app Skills panel.
- Search for
summarizerand click Install. - The skill activates automatically when an incoming message matches its description.
Install from the command line
If you already run the OpenClaw CLI, add the Summarizer skill with a single command:
openclaw skills add summarizer
This pulls summarizer from ClawHub and installs it into ~/.openclaw/skills/summarizer/. Restart the OpenClaw gateway afterwards so the new skill is discovered.
How to use the Summarizer skill
Once installed, the Summarizer skill activates on its own: when an incoming message on WhatsApp, Telegram, Slack, Discord, Feishu or Line matches the skill's description, your OpenClaw agent loads it and runs the workflow. You can also trigger it explicitly by describing the task in chat. No extra configuration is required after install.
Turning video into a finished short
Summarizer works with video. Getting from there to something postable is a separate job: ViralMint — an open-source video pipeline — reframes to vertical, cleans the audio, cuts dead air, burns animated captions, and exports a version sized for TikTok, Reels, and Shorts.
It runs as an MCP server, so an OpenClaw agent can drive it from the same chat you already use: ask for a short, and the render comes back finished. See how to connect a video pipeline to your agent.
