Background & analysis
On 2026-10-30, DEV Community's AI section introduced Context Mode. Quoting the Context Mode README, the piece notes that every MCP tool call dumps raw data into the context window: a single Playwright snapshot costs 56 KB, twenty GitHub issues cost 59 KB, and one access log is 45 KB. After roughly 30 minutes of work, around 40% of a Claude Code context can disappear, and once the conversation compacts, the agent forgets which files it was editing. Context Mode attacks this as an MCP server plus a set of hooks. It keeps raw tool output in a sandbox so that only a small result enters the conversation, and it tracks session events with SQLite. The article walks through a five-step installation process, after which bulky output such as Playwright snapshots and GitHub issues no longer fills the context directly. Only this one report is available, so the project's maintainers, release date, and any subsequent progress are not documented here.

Heat counts how many independent sources covered a story in the last 48 hours: one source counts once no matter how many posts it published, decaying with a 24-hour half-life. What ranks first is what many people are talking about.
