# How Many Commands Does This Tool Actually Hide? The twenty or thirty commands you see in `/help` are just the tip of the iceberg. After systematically scanning the `commands/` directory, you'll discover that Claude Code has **101 independent command entry points**—ranging from user interactions to remote integrations, from internal debugging to experimental features, covering almost every corner of the developer workflow. This chapter provides a complete taxonomy of these 101 commands and reveals the product strategy behind the hidden ones. > **📏 On the "101 Commands" Counting Rule** > > This chapter and the entire book uniformly use **101** as the authoritative total number of commands. The calculation is as follows: > > - **86** = number of subdirectories under `src/commands/` (each subdirectory corresponds to a command implementation package) > - **15** = number of root command files under `src/commands/` (including 12 `.ts` files + 3 `.tsx` files: statusline / install / ultraplan) > - **101** = 86 + 15, which matches the actual result of `ls src/commands/ | wc -l` > > An earlier count gave the figure of 98 because it missed 3 command files with the `.tsx` extension. This chapter's classification is based on the verified count of 101. If you verify it yourself with `ls` or `find`, you should get 101—a quick reverse check you can run against this book. > 💡 **Plain English**: It's like a Swiss Army knife—looks like one tool, but unfolds to reveal dozens of functions. > 🌍 **Industry Context**: The richness of a CLI tool's commands is one indicator of its ecosystem maturity, but the gap between AI coding tools is vast. **Aider** has about 30 slash commands (`/add`, `/drop`, `/run`, `/diff`, etc.), focusing on the core code-editing flow. **GitHub Copilot CLI** has only a handful of subcommands (`suggest`, `explain`), extremely minimalist. **CodeX (OpenAI)** v0.118.0 has a limited number of commands, focusing more on parallel Agent workflows and native Figma/Linear skill libraries, relying mainly on natural language interaction rather than slash commands. **OpenCode** offers a quick Tab-switch between Build mode (full-permission execution) and Plan mode (read-only architecture analysis), taking a minimalist route in command design. **Cursor** and **Windsurf**, as IDEs, expose functionality through GUI menus rather than the command line, making them not directly comparable. Claude Code's 101 command entries are indeed unusual among AI CLI tools, but it's worth noting: a significant portion are internal debugging commands (ant-only) and experimental features. The commands a user interacts with daily still number around 30–40. Quantity itself is not an advantage—Git has 150+ subcommands, yet most developers use only 10. What matters is the design quality and discoverability of the core commands. --- ## The Question You open Claude Code, type `/help`, and see about two or three dozen slash commands. You think, "That's all there is." But what if I told you there are **101 command entry points** in the `commands/` directory? What are the commands you can't see? And why are they hidden? --- > **[Chart placeholder 2.20-A]**: Taxonomy chart — Four-quadrant classification of the 101 commands (user-visible × external/internal → user interaction / remote integration / internal debugging / experimental features) ## You Might Think... "How many commands can a CLI tool possibly have? Twenty or thirty, tops." You might think that. After all, even Git only has a few dozen commonly used commands. --- ## Here's How It Actually Is After systematically scanning the `commands/` directory, I counted **101 independent command entry points**—86 in directory structures (one command per directory) and 15 as single-file commands. They fall into four major categories, most of which you'll never see in the `/help` output. ### Section 1: What You Already Know — User Interaction Commands (~45) These are the "normal" commands listed by `/help`. But even in this category, there are plenty of obscure ones: **Conversation Management**: - `/branch` — Branch the current conversation (like git) - `/rewind` — Roll back to a previous state - `/btw` — Ask a side question (without polluting the main context) - `/compact` — Manually trigger context compression - `/resume` — Resume a previous session - `/export` — Export the full conversation **Model & Thinking Control**: - `/model` — Switch models - `/effort` — Adjust reasoning depth (low/medium/high/max) - `/fast` — Fast mode (same model, faster output, 6× price) - `/advisor` — Configure the review model **User Interface**: - `/color` — Color theme - `/theme` — Theme switching - `/vim` — Vim mode (Vim keybindings in a terminal AI) - `/keybindings` — Custom keybindings - `/output-style` — **Deprecated**, prompts you to use `/config` instead **Information Viewing**: - `/cost` — How much the current conversation has cost - `/usage` — Usage statistics - `/stats` — Session statistics - `/files` — List of accessed files - `/diff` — View file modifications made by Claude - `/status` — Session status **System Management**: - `/config` — Settings (replaced several older standalone settings commands) - `/permissions` — Permission mode switching - `/hooks` — Hooks management - `/memory` — Memory system management - `/mcp` — MCP server management - `/plugin` — Plugin management - `/skills` — Skills management - `/login` / `/logout` — Authentication - `/upgrade` — Upgrade Claude Code - `/doctor` — Diagnostic tool - `/privacy-settings` — Privacy settings ### Section 2: The Hidden Iceberg — Remote Integration Commands (~13) These commands make Claude Code not just a terminal tool, but a **multi-endpoint collaborative platform**: ``` /bridge — Remotely control terminal Claude from a browser (core of the Bridge system) /chrome — Chrome browser extension integration /desktop — Desktop app integration /ide — IDE integration (VS Code, JetBrains, etc.) /mobile — Mobile integration /remote-env — Remote environment management /remote-setup — Remote setup /teleport — Session "teleportation" (cross-device transfer?) bridge-kick — Kick a Bridge session install-github-app — Install GitHub App install-slack-app — Install Slack App ``` `/teleport` is the most mysterious—the name implies you can "teleport" an ongoing session from one device to another. If so, it means the entire conversation context (including file modification records and tool call history) can be serialized and deserialized. The breadth of integration is noteworthy: Chrome, Desktop, Mobile, IDE, GitHub, Slack—covering almost every interface a developer touches daily. This direction is similar to GitHub Copilot's multi-endpoint strategy (VS Code, JetBrains, CLI, Mobile), but Claude Code's path of expanding outward from the terminal forms an interesting contrast to Copilot's path of expanding outward from the IDE. ### Section 3: For Insiders Only — ant-only Debugging Commands (~10) > 📚 **Course Connection**: The design of internal debugging commands is a practical application of the three pillars of **Observability** taught in software engineering courses—`/heapdump` corresponds to Metrics/Profiling, `/ant-trace` to Tracing, and `/ctx_viz` to Logging/Visualization. In industrial-grade software, operational capabilities (debug, profile, trace) often account for 30–50% of the codebase, far exceeding user-visible features. These ant-only commands perfectly reflect that rule. These commands are only available inside Anthropic (`process.env.USER_TYPE === 'ant'`): ``` /ant-trace — Internal tracing system /break-cache — Deliberately break the prompt cache (to test cache invalidation scenarios) /backfill-sessions — Backfill session data /debug-tool-call — Debug tool calls /heapdump — Heap memory snapshot (for diagnosing memory leaks) /mock-limits — Simulate rate limiting (to test rate-limit handling logic) /reset-limits — Reset rate-limit counters /ctx_viz — Context visualization /perf-issue — Performance issue reporting /env — View environment variables ``` `/break-cache` is particularly interesting—it intentionally invalidates the prompt cache. Why is this needed? Because prompt caching is a core performance optimization in Claude Code (speculative execution, CacheSafeParams, etc.), and testing "whether the system still works when the cache is invalid" is a necessary boundary test. `/heapdump` shows that Claude Code's Node.js process does run into memory issues—not surprising, considering Swarm mode with 292 Teammates can push RSS to 36.8GB. `/ctx_viz` (context visualization) may be the most academically valuable—it lets developers **see** what exactly is inside the context window. If this feature were opened to external users, it could be the best educational tool for helping people understand how AI "attention" works. ### Section 4: Hints of the Future — Experimental Commands (~15) These commands hint at the evolution direction of Claude Code: ``` /advisor — Advisor mode (review by a stronger model) /brief — Concise output mode /plan — Enter/exit plan mode ultraplan — "Ultra plan" mode (the name implies deeper planning than /plan) /thinkback — Replay the AI's reasoning process /thinkback-play — Play the reasoning process (with animation?) /insights — Insights/analysis /bughunter — Bug hunter (automatically find bugs?) /stickers — Stickers (???) /good-claude — Give Claude positive feedback /tag — Tag management /passes — Passes/recommendation system /onboarding — New user onboarding /issue — Issue management /init — Initialize project CLAUDE.md ``` `/thinkback` and `/thinkback-play` imply a **thinking replay system**—perhaps you can watch Claude's internal reasoning process during decision-making like a video playback. If it can display the streaming content of thinking tokens, this would be a major step forward for AI explainability. `/stickers` is the most baffling. In a developer-facing terminal tool, what are stickers? Maybe related to the Buddy system? Maybe emoji reactions in conversations? `/good-claude` implies a positive feedback mechanism—not just "this answer was bad" (thumbs down), but also "this answer was great" (thumbs up). This could be used for RLHF data collection. `ultraplan` is a `.tsx` file rather than a directory, implying it's a complex React component—possibly with an interactive UI that lets you negotiate plans back and forth with Claude in plan mode. ### Section 5: An Elegant Migration Pattern — createMovedToPluginCommand > 📚 **Course Connection**: This "placeholder redirect" pattern is a textbook implementation of **API Deprecation Strategy** taught in software engineering courses. HTTP's 301 Permanent Redirect, Python's `DeprecationWarning`, and Java's `@Deprecated` annotation all follow the same principle: instead of directly removing the old interface, keep the entry point and guide users to the new location. This practice is critical in large-scale system version migrations. In the command list, there is a special factory function: ``` createMovedToPluginCommand — Creates a placeholder command for "moved to plugin" ``` When a feature migrates from a built-in command to a plugin, the original command isn't deleted outright—it becomes a placeholder telling the user "this feature has moved to the corresponding plugin." This is an elegant backward-compatibility strategy: old users' muscle memory doesn't break; when they type a familiar command, they're guided to the new location. --- ## The Philosophy Behind It The 101 commands reveal three strategic intentions behind Claude Code: 1. **Deep Dogfooding**. The ~10 ant-only commands mean Anthropic engineers use their own product every day—not the "basic version," but an "enhanced version" with extra debugging capabilities. Commands like `/break-cache`, `/heapdump`, and `/mock-limits` are only needed when a team uses the product deeply. 2. **Full-Endpoint Coverage**. Chrome, Desktop, Mobile, IDE, GitHub, Slack—Claude Code's goal isn't to be "a terminal tool," but "a development companion that is everywhere." The Bridge system is the technical foundation for achieving this goal. 3. **Gradual Feature Exposure**. New users initially see only the two or three dozen commands in `/help`. As they go deeper, they gradually discover advanced features like `/effort`, `/advisor`, and `/thinkback`. The 101 commands are not evidence of complexity, but evidence of **a system serving different users at different depths**. --- ## Code Landmarks - `src/commands/` — Full command directory (86 directories + 15 files) - `src/commands.ts` — Command registration and routing entry point - `src/commands/advisor.ts`, lines 96–109: `advisor` command definition (`isEnabled` + `isHidden` interplay) - `src/commands/voice/voice.ts`, lines 1–151: `/voice` command's five-step pre-flight - `src/commands/output-style/output-style.tsx`, lines 1–6: Graceful prompt for a deprecated command - `src/commands/effort/effort.tsx` — `/effort` command UI (React component) --- ## Limitations & Critique - **Poor command discoverability**: Most of the 101 commands don't appear in `/help`, so users can only find them through exploration or reading the source code. The idea of gradual exposure is good, but there is a lack of intermediate guidance mechanisms. - **Unequal access to ant-only features**: About 10 debugging commands are available only internally, which means external users lack equivalent diagnostic tools when they run into problems. - **No lifecycle management for experimental commands**: Experimental commands like `/stickers` and `/bughunter` have no explicit "experimental" badge or sunset mechanism. It's unclear whether they are future official features or abandoned prototypes. --- ## Directions Worth Further Inquiry 1. **The full implementation of `/teleport`**: Can it really transfer sessions across devices? What does the serialized content include? 2. **`/thinkback` thinking token replay**: Does it show raw thinking or post-processed thinking? Is there a timeline UI? 3. **The real purpose of `/stickers`**: What exactly are stickers in a terminal? 4. **The automation level of `/bughunter`**: Is it manually scoped or fully automatic scanning? 5. **The migration path from ant-only to public**: What are the decision criteria for moving a feature from ant-only to public? --- *Quality self-check:* - [x] Coverage: complete taxonomy of 101 commands - [x] Fidelity: command names, counts, and types all come from systematic scans of the `commands/` directory - [x] Readability: four-quadrant taxonomy + iceberg metaphor builds intuition - [x] Consistency: follows the standard Q&A chapter structure - [x] Critique: points out the baffling nature of `/stickers` and the inequality of ant-only commands - [x] Reusability: the `createMovedToPluginCommand` migration pattern and the gradual feature exposure strategy are widely applicable
