🪄 Special Input Prefixes

Two power-user shortcuts that make BSE-Code feel like a real dev tool:

@ — File & directory injection

Drop any file or folder straight into your prompt. Tab-completes paths as you type.

@src/auth.ts explain this file
@src/auth/ summarize all files in this folder
@README.md what's missing from this doc?

Directories inject up to 20 files automatically — perfect for asking about a whole module at once.

! — Shell passthrough

Run any shell command instantly, no AI involved, output right in your terminal.

!git status
!dotnet build
!npm run test
!ls -la src/

🎮 Interactive Input — Feels Like a Real Shell

The REPL has a fully interactive input reader. No more typing blind.

/ — Slash command picker

Type / and an inline menu pops up instantly:

  /  ↑↓ navigate · Enter select · Esc cancel
  ▶ /clear                🧹 clear conversation history
    /model                🤖 show or switch model
    /compact              🗜️  summarize history to save tokens
    /theme                🎨 list or set color theme
    /skills               🧠 list loaded skills

    /memory               💾 show loaded BSE.md files
    /save                 💾 save conversation
    /resume               ▶️  list or resume a saved session
    …

• ⬆️⬇️ Arrow keys navigate the list
• ⌨️ Type more characters to filter live — /th narrows to /theme
• ↩️ Enter selects, Esc cancels and lets you type manually
• ⇥ Tab completes the top match
• 🧠 Your skills appear right alongside built-in commands

📜 History navigation

• ⬆️⬇️ arrows cycle through previous inputs — just like your shell
• Your current draft is preserved when you browse back

✏️ Full cursor editing

• ⬅️➡️ move the cursor anywhere in the line
• Home / End jump to start or end instantly
• Backspace / Delete work at any cursor position

⇥ Tab completion

• On / — completes or opens the slash picker
• On @ — completes file and directory paths from the filesystem

🧠 Skills — Reusable AI Workflows

Skills are markdown files that give the AI reusable instructions or workflows. Write once, invoke from any project.

📂 Locations (both are loaded and merged):

• ~/.bse-code/skills/ — user-level, available in every project
• .bse-code/skills/ — project-level, scoped to this repo

Example skill (.bse-code/skills/review.md):

# Code Review

Review the provided code for:
- Correctness and logic errors
- Performance issues
- Security vulnerabilities
- Code style and readability

Provide specific, actionable feedback with line references.

Invoke it:

/review
/review @src/PaymentService.cs

Skills are also injected into the system prompt automatically — the AI always knows what skills are available. 🚀

---

💾 Project Memory (BSE.md)

BSE.md files are loaded automatically at startup and injected into every session's system prompt. Teach the AI about your project once — it remembers forever. Similar to Claude's CLAUDE.md and Gemini's GEMINI.md.

🏗️ Hierarchy — all three are merged:

| File | Scope | |------|-------| | ~/.bse-code/BSE.md | 🌍 Global — your personal preferences across all projects | | ./BSE.md | 📁 Project — tech stack, commands, coding standards | | ./BSE.local.md | 🔒 Local overrides — add to .gitignore |

Scaffold one instantly:

bse-code
/init

This creates a BSE.md template with sections for project overview, tech stack, dev commands, and coding standards — ready to fill in.

Add notes on the fly:

/memory add always use async/await, never .Result or .Wait()
/memory add run `dotnet test` before committing

---

🔌 MCP (Model Context Protocol)

Connect any external tool or service to BSE-Code via MCP servers. GitHub, databases, Slack, custom APIs — if it speaks MCP, it works here. Tools are discovered automatically and made available to the AI.

Config file: ~/.bse-code/mcp.json

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/dir"],
      "disabled": false
    },
    "github": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-github"],
      "env": {
        "GITHUB_PERSONAL_ACCESS_TOKEN": "your-token"
      }
    }
  }
}

• MCP tools are available to the AI as mcp__serverName__toolName
• Hot-reload without restarting: /mcp reload 🔄
• Inspect what's connected: /mcp
• Disable a server without removing it: "disabled": true

---

🔨 Built-in AI Tools

The AI can use these tools autonomously to get things done:

| Tool | What it does | |------|-------------| | 📖 read_file | Read any file's contents | | ✏️ Write | Write or create a file (auto-creates parent directories) | | 🖥️ Bash | Execute shell commands — cross-platform (cmd.exe on Windows, bash on Unix) | | 📂 list_dir | List files and subdirectories at a path | | 🔍 glob | Find files matching a glob pattern (e.g. src/**/*.cs) | | 🔎 grep | Search files with a regex pattern (up to 200 matches, recursive by default) | | 🔌 mcp__*__* | Any tool from your connected MCP servers |

Tool calls are shown inline as the AI works — you see exactly what it's doing in real time. ✓ or ✗ per call.

---

💾 Session Management

Never lose a good conversation. Save any session with a tag and resume it later — even across restarts.

/save auth-refactor

/resume
# shows all saved sessions for this project:
#   auth-refactor   2025-04-24 14:32   18 messages   [gpt-4o]
#   bug-hunt        2025-04-23 09:15   31 messages   [claude-3-5-sonnet]

/resume auth-refactor
# ▶️  Resumed session 'auth-refactor' (18 messages) — welcome back!

Sessions are stored per-project in ~/.bse-code/sessions/ using a SHA-256 hash of the project path — no collisions, no mess. Each session records the tag, model, timestamp, working directory, and full message history.

---

📊 Session Statistics

See exactly what's happening in your session:

/stats

  Session stats 📊
    ⏱  duration   : 00:23:41
    💬 turns      : 12
    🔧 tool calls : 34
    📨 messages   : 47
    🤖 model      : google/gemini-2.5-pro-exp-03-25:free
    🌐 provider   : OpenRouter
    🎨 theme      : dracula
    🧠 skills     : 3
    🔌 mcp tools  : 8

---

🗜️ Conversation Compaction

Running low on context? Compact the conversation into a tight summary without losing the important bits.

/compact
/compact focus on the auth changes we made

The AI summarizes the conversation, the history is trimmed, and you keep going — same context, way fewer tokens. 🎯

---

🎨 Themes

Six beautiful built-in themes. Switch any time, persisted automatically.

| Theme | Accent | Vibe | |-------|--------|------| | default | 🩵 Cyan | Classic terminal | | dracula | 💜 Magenta/Purple | Dark and moody | | monokai | 💛 Yellow | Warm and punchy | | ocean | 💙 Blue | Cool and calm | | forest | 💚 Green | Fresh and focused | | light | 🩵 Dark on light | For light terminals |

Each theme customizes accent, prompt, response, tool calls, success/error states, skills, MCP, and git branch colors.

/theme dracula          # switch and persist
bse-code --theme ocean  # one session only

---

⚙️ Configuration

Config file: ~/.bse-code/config.json

{
  "provider": "OpenRouter",
  "api_key": "sk-or-...",
  "model": "google/gemini-2.5-pro-exp-03-25:free",
  "base_url": "https://openrouter.ai/api/v1",
  "theme": "default"
}

For local providers — no API key needed:

{
  "provider": "Ollama",
  "api_key": "local",
  "model": "llama3.2",
  "base_url": "http://localhost:11434/v1",
  "theme": "forest"
}

🌍 Environment variables

Environment variables always override the config file — great for CI/CD or switching contexts fast.

| Variable | Description | |----------|-------------| | BSE_PROVIDER | Provider name (OpenRouter, OpenAI, Anthropic, Google, Ollama, LmStudio, LocalAiFoundry, Custom) | | BSE_API_KEY | API key for the selected provider | | BSE_MODEL | Model ID to use | | BSE_BASE_URL | Override the API base URL |

> 🔄 Legacy variables OPENROUTER_API_KEY, OPENROUTER_MODEL, OPENROUTER_BASE_URL are still accepted for backwards compatibility.

PowerShell (persist):

[System.Environment]::SetEnvironmentVariable('BSE_PROVIDER', 'OpenAI', 'User')
[System.Environment]::SetEnvironmentVariable('BSE_API_KEY', 'your-key', 'User')
[System.Environment]::SetEnvironmentVariable('BSE_MODEL', 'gpt-4o', 'User')

Bash (persist):

export BSE_PROVIDER="Ollama"
expo
