-## Executive Summary
+## 🆕 UPDATE 2026-02-01: Extended Fork Available
+
+**Fork Status**: An extended fork by FlorianBruniaux adds critical missing features:
+
+| Feature | Upstream v0.2.0 | Fork v0.4.0+ |
+|---------|----------------|--------------|
+| **JS/TS Stack** | ❌ Not supported | ✅ `rtk vitest`, `rtk pnpm`, `rtk prisma` |
+| **Bug Fixes** | ❌ grep/ls broken | ✅ Fixed in fork |
+| **Analytics** | ❌ None | ✅ `rtk gain`, `rtk discover` |
+| **Token Savings** | 72.6% (git only) | 70-90% (full stack) |
+
+**Fork Highlights**:
+- ✅ `rtk vitest run` - 90% reduction on test outputs
+- ✅ `rtk pnpm list` - 70% reduction on package trees
+- ✅ `rtk prisma migrate` - Migration status filtered
+- ✅ `rtk gain` - Token savings analytics dashboard
+- ✅ `rtk discover` - Find missed optimization opportunities
+- ✅ Bug fixes: grep and ls now work correctly
+
+**Installation (Fork)**:
+```bash
+git clone https://github.com/FlorianBruniaux/rtk.git
+cd rtk && git checkout feat/all-features
+cargo install --path . --force
+```
+
+**Recommendation Update**: Fork addresses all critical gaps identified in this evaluation. For modern JS/TS stacks (T3 Stack, Next.js, etc.), **use the fork**. For git-only workflows, upstream remains stable.
+
+---
+
+## Executive Summary (Original Evaluation - Upstream v0.2.0)

 RTK (Rust Token Killer) is a high-performance CLI proxy that filters and compresses command outputs **before they reach LLM contexts**. Real-world testing on the Claude Code Ultimate Guide repository confirms **72.6% average token reduction** across git workflows (92.3% for `git log`), validating the advertised 70% savings claim.

+
+## About This Page
+
+This page catalogs **community-built tools that extend Claude Code**. Each tool has been verified against its public repository or package registry. Only tools with a public source (GitHub, npm, PyPI) are included.
+
+**What this page is NOT**:
+- Not a list of AI tools that complement Claude Code (see [AI Ecosystem](./ai-ecosystem.md))
+- Not DIY monitoring scripts (see [Observability](./observability.md))
+- Not MCP server recommendations (see [MCP Servers Ecosystem](./mcp-servers-ecosystem.md))
+
+---
+
+## Token & Cost Tracking
+
+### ccusage
+
+The most mature cost tracking tool for Claude Code. Parses local session data to produce cost reports by day, month, session, or 5-hour billing window.
+
+| Attribute | Details |
+|-----------|---------|
+| **Source** | [npm: ccusage](https://www.npmjs.com/package/ccusage) / [ccusage.com](https://ccusage.com) |
+| **Install** | `bunx ccusage` (fastest) or `npx ccusage` |
+| **Language** | TypeScript (Node.js 18+) |
+| **Version** | 18.x (actively maintained) |
+
+**Key features**:
+
+- `ccusage daily` / `ccusage monthly` / `ccusage session` - aggregated cost reports
+- `ccusage blocks --live` - real-time monitoring against 5-hour billing windows
+- `--breakdown` flag for per-model cost split (Opus/Sonnet/Haiku)
+- `--since` / `--until` date filtering
+- JSON output (`--json`) for programmatic access
+- Offline mode with cached pricing data
+- MCP server integration (`@ccusage/mcp`)
+- macOS widget (`ccusage-widget`) and [Raycast extension](https://www.raycast.com/nyatinte/ccusage)
+
+**Limitations**: Relies on local JSONL parsing; cost estimates may differ from official Anthropic billing. No team aggregation without manual log merging.
+
+> **Cross-ref**: The main guide covers basic ccusage commands at [ultimate-guide.md Section 2.4](./ultimate-guide.md) (cost monitoring).
+> For DIY cost tracking with hooks, see [Observability](./observability.md).
+
+---
+
+### ccburn
+
+A Python TUI for visual token burn-rate tracking. Displays charts showing consumption rate relative to Claude's billing windows.
+
+| Attribute | Details |
+|-----------|---------|
+| **Source** | [GitHub: JuanjoFuchs/ccburn](https://github.com/JuanjoFuchs/ccburn) / [Blog post](https://juanjofuchs.github.io/ai-development/2026/01/13/introducing-ccburn-visual-token-tracking.html) |
+| **Install** | `pip install ccburn` |
+| **Language** | Python 3.10+ (Rich + Plotext) |
+
+**Key features**:
+
+- Terminal charts showing token consumption over time
+- Burn-rate indicators (on-track / slow-down warnings)
+- Compact display mode
+- Visual budget tracking against limits
+
+**Limitations**: Python-only ecosystem. Smaller community than ccusage. No MCP integration.
+
+**When to choose ccburn over ccusage**: If you prefer visual burn-rate charts over tabular reports, or if your toolchain is Python-based.
+
+---
+
+### RTK (Rust Token Killer)
+
+A CLI proxy that filters command outputs **before** they reach Claude's context.
+
+| Attribute | Details |
+|-----------|---------|
+| **Source** | [GitHub: pszymkowiak/rtk](https://github.com/pszymkowiak/rtk) (upstream stable) |
+| **Fork** | [GitHub: FlorianBruniaux/rtk](https://github.com/FlorianBruniaux/rtk) (extended features) |
+| **Install** | `cargo install rtk` or binary download |
+| **Language** | Rust (standalone binary) |
+| **Version** | v0.2.0+ (upstream), v0.4.0+ (fork) |
+
+**Key features**:
+
+- `rtk git log` (92% reduction), `rtk git status` (76% reduction), `rtk git diff` (56% reduction)
+- `rtk vitest run`, `rtk prisma`, `rtk pnpm` (fork only, 70-90% reduction)
+- `rtk gain` - token savings analytics
+- `rtk discover` - find missed optimization opportunities (fork only)
+
+**Two versions:**
+
+- **Upstream** (pszymkowiak): Stable, git/find/cat focus, minimal dependencies
+- **Fork** (FlorianBruniaux): Adds JS/TS stack support (vitest, pnpm, prisma), bug fixes (grep, ls), analytics
+
+**When to choose RTK vs ccusage/ccburn**:
+
+- RTK **reduces** token consumption (preprocessing)
+- ccusage/ccburn **monitor** it (postprocessing)
+- Use both together for maximum efficiency
+
+**Limitations**: Early-stage project. Upstream has grep/ls bugs (fixed in fork). Not suitable for interactive commands or very small outputs.

+**Limitations**: Third-party, not Anthropic-maintained. Feature set may overlap with or lag behind the official extension.
+
+---
+
+## Multi-Agent Orchestration
+
+This section covers tools for running **multiple Claude Code instances in parallel**. For detailed documentation, see:
+
+- **[AI Ecosystem](./ai-ecosystem.md)** - Gas Town, multiclaude, agent-chat, claude-squad
+- **[Ultimate Guide Section 9](./ultimate-guide.md)** - Multi-instance workflows, git worktrees, orchestration frameworks
+
+**Quick reference**:
+
+| Tool | Type | Key Feature |
+|------|------|-------------|
+| [Gas Town](https://github.com/steveyegge/gastown) | Multi-agent workspace | Steve Yegge's agent-first workspace manager |
+| [multiclaude](https://github.com/dlorenc/multiclaude) | Multi-agent spawner | tmux + git worktrees (383+ stars) |

+| [Conductor](#conductor) | Desktop app | macOS parallel agents (also listed above) |
+
+---
+
+## Plugin Ecosystem
+
+Claude Code's plugin system supports community-built extensions. For detailed documentation:
+
+- **[Ultimate Guide Section 8](./ultimate-guide.md)** - Plugin system, commands, installation
+- **[claude-plugins.dev](https://claude-plugins.dev)** - 11,989 plugins, 63,065 skills indexed
+- **[claudemarketplaces.com](https://claudemarketplaces.com)** - Auto-scan GitHub for marketplace plugins
+- **[agentskills.io](https://agentskills.io)** - Open standard for agent skills (26+ platforms)
+
+---
+
+## Known Gaps
+
+As of February 2026, the community tooling ecosystem has notable gaps:
+
+| Gap | Description |
+|-----|-------------|
+| **Visual skills editor** | No GUI for creating/editing `.claude/skills/` — must edit YAML/Markdown manually |
+| **Visual hooks editor** | No GUI for managing hooks in `settings.json` — requires JSON editing |
+| **Unified admin panel** | No single dashboard combining config, sessions, cost, and MCP management |
+| **Session replay** | No tool replays sessions with playback controls (only static viewing) |
+| **Per-MCP-server profiler** | No way to measure token cost attributable to each MCP server individually |
+| **Cross-platform config sync** | No tool syncs Claude Code config across machines (must manual copy `~/.claude/`) |
+
+---
+
+## Recommendations by Persona
+
+| Persona | Recommended Tools | Rationale |
+|---------|-------------------|-----------|
+| **Solo developer** | ccusage + claude-code-viewer | Cost awareness + session history review |
+| **Small team (2-5)** | ccusage + Conductor or multiclaude | Cost tracking + parallel development |
+| **Enterprise** | ccusage (MCP) + custom dashboards | Programmatic cost data + audit trails |
+| **Python-centric** | ccburn + Claude Chic | Native Python ecosystem tools |
+| **Multi-agent user** | Toad or Conductor | Unified agent management |
+| **Config-heavy setup** | claude-code-config + AIBlueprint | TUI config management + scaffolding |
