Show HN: Capture context. Give your agent the full picture (github.com)
1 points by semihcihan 119 days ago
Context Brief is an Open Source macOS menu bar app that captures high-signal context from the app you’re in (GitHub, Jira, Slack, Notion, web pages, and more) with ⌃⌘C, then pastes one clean, agent-ready brief with ⌃⌘V. Unlike copy-paste tools, it extracts beyond visible content, densifies noisy text, combines multiple snapshots into one task context, and keeps a local context library on-device.

A lot of agent failures I’ve seen come from small details getting dropped when context is summarized or compressed.

How do you make sure the densification step doesn’t remove something that ends up being important for the task?

You’re right that it’s important to keep facts, numbers, constants, and the like and that’s exactly how the agent is prompted. It’s not really summarization, it’s removing noise (UI chrome, menus, repeated labels, etc.) while keeping all the numbers and facts. I’ve been using the tool myself for a while and it’s held up well. If we find that keeping everything as-is works better, we can always turn off densification and keep the raw capture.
