{ "name": "context-os", "description": "Claude Code context optimizer. Builds a local static repo graph, injects ranked file:line candidates through a UserPromptSubmit hook, and adds a SessionStart prewarm brief. No embeddings, no server, no telemetry. Measured live A/B: 40.9% aggregate token reduction across 36 Claude Code calls. v2.10 structural slicing: a PreToolUse hook intercepts whole-file reads and hands Claude the file's outline (symbols + exact line ranges from the graph) so it reads the 40 lines it needs, not 800 that get re-sent every turn. Receipts (/savings) measure both sources \u2014 searches avoided and big reads sliced \u2014 causally from your transcript.", "version": "2.10.2", "author": { "name": "sravan27", "url": "https://github.com/sravan27" }, "homepage": "https://github.com/sravan27/context-os", "repository": "https://github.com/sravan27/context-os", "license": "MIT", "keywords": [ "claude", "claude-code", "token-optimization", "repo-graph", "symbol-index", "hooks", "compaction", "context", "slash-commands" ] }
