npx claudepluginhub mksglu/context-modeMCP server that saves 98% of your context window with session continuity. Sandboxed code execution in 11 languages, FTS5 knowledge base with BM25 ranking, and automatic state restore across compactions.
mksgluThe other half of the context problem.
Every MCP tool call dumps raw data into your context window. A Playwright snapshot costs 56 KB. Twenty GitHub issues cost 59 KB. One access log — 45 KB. After 30 minutes, 40% of your context is gone. And when the agent compacts the conversation to free space, it forgets which files it was editing, what tasks are in progress, and what you last asked for.
Context Mode is an MCP server that solves all three sides of this problem:
--continue, previous session data is deleted immediately — a fresh session means a clean slate.console.log()s only the result. One script replaces ten tool calls and saves 100x context. This is a mandatory paradigm across all 12 platforms: stop treating the LLM as a data processor, treat it as a code generator.
Platforms are grouped by install complexity. Hook-capable platforms get automatic routing enforcement. Non-hook platforms need a one-time routing file copy.
Prerequisites: Claude Code v1.0.33+ (claude --version). If /plugin is not recognized, update first: brew upgrade claude-code or npm update -g @anthropic-ai/claude-code.
Install:
/plugin marketplace add mksglu/context-mode
/plugin install context-mode@context-mode
Restart Claude Code (or run /reload-plugins).
Verify:
/context-mode:ctx-doctor
All checks should show [x]. The doctor validates runtimes, hooks, FTS5, and plugin registration.
Routing: Automatic. The SessionStart hook injects routing instructions at runtime — no file is written to your project. The plugin registers all hooks (PreToolUse, PostToolUse, PreCompact, SessionStart) and 6 sandbox tools (ctx_batch_execute, ctx_execute, ctx_execute_file, ctx_index, ctx_search, ctx_fetch_and_index).
| Slash Command | What it does |
|---|---|
/context-mode:ctx-stats | Context savings — per-tool breakdown, tokens consumed, savings ratio. |
/context-mode:ctx-doctor | Diagnostics — runtimes, hooks, FTS5, plugin registration, versions. |
/context-mode:ctx-upgrade | Pull latest, rebuild, migrate cache, fix hooks. |
/context-mode:ctx-purge | Permanently delete all indexed content from the knowledge base. |
Note: Slash commands are a Claude Code plugin feature. On other platforms, type
ctx stats,ctx doctor, orctx upgradein the chat — the model calls the MCP tool automatically. See Utility Commands.
