10x-Code is a production-grade context engineering middleware built by the 10x Team that sits between your queries and Claude Code. It ensures every interaction has precisely the right context — no wasted tokens exploring irrelevant files, no losing track of what changed.
Before 10x-Code: Claude Code explores your codebase from scratch on every query, reading files it doesn't need, losing context when the window fills up.
With 10x-Code: Your codebase is indexed once, only relevant files are read per query, and everything is tracked in local MD files that persist across sessions.
- 23 slash commands across 6 categories — context, workflow, testing, research, git, operations
- 6 specialist agents — context builder, test runner, code auditor, git tracker, knowledge guide, team lead
- Dependency-aware indexing — files ranked by import centrality, not just name matching
- Zero-token context injection — Glob + Grep lookups cost no API tokens
- Session persistence — commit-style task logging in local MD files
- Hook system — automated lifecycle hooks for session management and path protection
- MCP server integration — remote tools endpoint at
10x.in/api/mcp - Cross-model optimized — Haiku for scanning, Sonnet for coding, Opus for reasoning

Scans your entire codebase and generates local reference files in .ccs/:
- project-map.md — File tree + dependency graph (imports/exports/references)
- architecture.md — Tech stack, patterns, entry points, data flow
- file-index.md — Files ranked by importance (most-imported = highest rank)
- conventions.md — Coding style, naming patterns, test patterns
When you ask Claude Code anything, the skill:
- Looks up the pre-built index for matching files/symbols
- Runs targeted Glob + Grep (zero API cost) to find candidates
- Follows import/dependency chains of matched files
- Claude Code reads ONLY the files that matter
Every action is logged in .ccs/task.md with git-commit-style entries:
- Task description, files read/modified/created/deleted
- Dependencies identified, status, diff summary
- Persists context without consuming API tokens
| Agent | Role |
|---|---|
| Context Builder | Deep codebase analysis, generates .ccs/ index files |
| Test Runner | Runs tests, tracks results, auto-fixes failures |
| Code Auditor | Security, performance, dead code, accessibility audits |
| Git Tracker | Git workflow — branches, PRs, merges, diffs, sync |
| Knowledge Guide | Proactive methodology guidance, note quality, connection suggestions |
| Team Lead | Multi-agent team coordination, task decomposition, parallel dispatch |
| Model | Used For | Commands |
|---|---|---|
| Haiku 4.5 | Lightweight lookups, scanning, status checks | status, refresh, query, track, stash, log |
| Sonnet 4.6 | Standard coding execution | build, fix, test, branch, sync |
| Opus 4.6 | Deep reasoning, architecture, complex analysis | init, plan, refactor, audit, review, research, deploy, pr, merge, diff, team |
The plugin ships with a .mcp.json that configures the CCS remote MCP server automatically:
{
"mcpServers": {
"ccs": {
"type": "http",
"url": "https://10x.in/api/mcp"
}
}
}This provides 6 MCP tools: skill info, all 23 command docs, OS-specific install commands, model strategy, and context file details. Run /ccs-connect to configure or verify.
Automated lifecycle hooks for session management. All hooks are Node.js — fully cross-platform (Windows, Mac, Linux), zero bash dependency.
| Hook | Trigger | What It Does |
|---|---|---|
path-guard.js |
PreToolUse | Blocks writes to immutable paths, warns on guarded paths |
session-orient.js |
SessionStart | Injects workspace tree, goals, conditions, maintenance signals |
session-summary.js |
SessionStart | Injects compact project summary for prompt cache hits |
context-inject.js |
UserPromptSubmit | Injects relevant context on every query via CCS engine |
index-update.js |
PostToolUse | Incrementally updates index after file writes/edits |
write-validate.js |
PostToolUse | Validates YAML frontmatter on note files |
auto-commit.js |
PostToolUse | Auto-commits changes to git after writes |
session-capture.js |
Stop | Saves session state, commits artifacts |
Hooks are automatically registered in ~/.claude/settings.json during installation with absolute node paths — no PATH dependency.
All context files are stored in .ccs/ (add to .gitignore):
