Compress OpenClaw session context to reduce token usage and extend session lifetime. Uses NLP summarization (Sumy) to intelligently compact conversation history while preserving essential context. Triggers on mentions of session compression, token reduction, context cleanup, or when session size exceeds safe thresholds (~300KB). Use when (1) OpenClaw approaches 50% context limit, (2) Sessions are slowing down due to large context, (3) Reducing API costs from excessive token consumption, (4) Extending session lifetime without forced reboots.

AI Agent & AutomationWhat Session Context Compressor can do for your AI workflow
Batch-compress images before uploading them to your website or CDN
Optimize video files for web delivery without manual transcoding
Automatically compress build artifacts as part of your CI/CD pipeline
Reduce PDF file sizes for email attachments or document sharing
Try these prompts with your AI agent after installing Session Context Compressor
Compress all images in this folder to under 200KB without visible quality loss
Processes each image with adaptive quality settings, targets sub-200KB output, and reports the before/after sizes for each file
Optimize this video for web playback and reduce its file size by 50%
Re-encodes the video with web-optimized settings (H.264, faststart), targets 50% size reduction, and returns the output file path
Compress this PDF and tell me the before/after file sizes
Applies PDF compression (image downsampling, font subsetting), then reports the original and compressed sizes with percentage saved

10 Fresh GitHub Agent Skills Added in June 2026
A hand-checked shortlist of recently updated GitHub agent skills that were not already in our catalog, excluding marketplaces, awesome lists, managers, and generic skill directories.
The 7 AI Skills Every Software Developer Should Have Installed in 2026
After testing dozens of developer-focused AI skills, these are the seven that have proven genuinely useful across different tech stacks and workflows β not just impressive demos, but tools that hold up under daily use.
Clawpressor is a file compression and optimization skill for AI agents, enabling automated compression of images, videos, and other assets directly within your workflow. Large file sizes slow down websites, increase storage costs, and hurt user experience. Clawpressor lets your AI agent compress and optimize files on demand without switching to a separate tool.
Session Context Compressor works across Claude, Cursor, OpenClaw through the Model Context Protocol (MCP) β an open standard that lets AI clients share tools and skills without lock-in. Because MCP is platform-agnostic by design, you install Session Context Compressor once and it becomes available across all your AI clients. Whether you're working in Claude for focused sessions or Cursor for integrated workflows, the skill behaves consistently.
Session Context Compressor installs like any other MCP skill: drop the folder into `~/.claude/skills/clawpressor/` for global access, or `.claude/skills/clawpressor/` to keep it scoped to one project. After a quick restart of Claude, you can trigger it explicitly with `/clawpressor`, or let the AI decide when it's the right tool for your request.
Session Context Compressor has 855 installs and is part of the growing AI Agent & Automation skill ecosystem on DiscoverAISkills. The source code is open on GitHub β you can inspect it, contribute fixes, or fork it to adapt the skill for your specific setup. Like all skills on DiscoverAISkills, it is free to install and use. The broader AI skills ecosystem continues to expand as developers contribute new capabilities across categories like developer tools, data analysis, writing, automation, and more.
Place the skill folder at ~/.claude/skills/clawpressor/ for personal use (all projects), or .claude/skills/clawpressor/ for project-specific use. Restart your AI client, then invoke with /clawpressor or let the AI discover it automatically.
Session Context Compressor supports Claude, Cursor, OpenClaw. It integrates seamlessly with these AI platforms to extend their capabilities.
Session Context Compressor is free to install. Check the repository for licensing information.
