Everything else → your coding agent. + +### What Gets Routed to Cortex Code? + +✅ **Routes to Cortex:** +- Snowflake databases, warehouses, schemas, tables +- SQL queries specifically for Snowflake +- Cortex AI features (Cortex Search, Cortex Analyst, ML functions) +- Snowpark, dynamic tables, streams, tasks +- Data governance, data quality in Snowflake +- Snowflake security, roles, policies +- User explicitly mentions "Cortex" or "Snowflake" + +❌ **Stays with your agent:** +- Local file operations (reading, writing, editing local files) +- General programming (Python, JavaScript, etc. not Snowflake-specific) +- Non-Snowflake databases (PostgreSQL, MySQL, MongoDB, etc.) +- Web development, frontend work +- Infrastructure/DevOps unrelated to Snowflake +- Git operations, GitHub, version control + +## Security + +### Three Approval Modes + +| Mode | Security | Use Case | +|------|----------|----------| +| **prompt** (default) | High | Interactive sessions, production | +| **auto** | Medium | Automated workflows, CI/CD | +| **envelope_only** | Medium | Trusted environments, faster | + +Configure in `config.yaml` in the skill's install directory (for skill-based agents) or `~/.local/lib/cortexcode-tool/config.yaml` (for CLI-based agents): +```yaml +security: + approval_mode: "prompt" # or "auto" or "envelope_only" +``` + +### Security Envelopes + +| Envelope | Use Case | Blocked Tools | +|----------|----------|---------------| +| **RO** (Read-Only) | Queries and reads | Edit, Write, Bash | +| **RW** (Read-Write) | Data modifications | Bash and destructive shell patterns | +| **RESEARCH** | Exploratory work | Edit, Write, Bash | +| **DEPLOY** | Deployment operations | Requires explicit confirmation; blocks Bash/destructive shell | +| **NONE** | No managed execution | Rejected before Cortex execution | + +### Built-in Protections + +1. **Prompt Sanitization**: Automatic removal of PII (emails, SSN, credit cards) +2. **Credential Blocking**: Prevents routing when paths like `~/.ssh/`, `.env` are detected +3. **Secure Caching**: HMAC-signed capability cache under `~/.cache/cortex-skill/` +4. **Audit Logging**: Tamper-evident JSONL logs with hash chaining, including prompt-mode approval requests +5. **Envelope Gate**: Requested envelopes must be present in `security.allowed_envelopes` before routing, approval, or Cortex execution +6. **Organization Policy**: Enterprise admins can enforce settings via `~/.snowflake/cortex/claude-skill-policy.yaml`; relaxed approval/envelope settings must be explicitly authorized +7. **Private Installs**: Installers use private permissions (`0700` directories, `0600` sensitive config/log files) + +See [SECURITY.md](SECURITY.md) and [SECURITY_GUIDE.md](SECURITY_GUIDE.md) for full details. + +## How It Works + +### Dynamic Skill Discovery + +The integration automatically discovers Cortex Code's native capabilities at session start: + +1. Runs `cortex skill list` to enumerate all available skills (32+ bundled in v1.0.42) +2. Reads each skill's `SKILL.md` from `~/.local/share/cortex/{version}/bundled_skills/` +3. Extracts trigger patterns ("data quality", "semantic view", "DMF", etc.) +4. Caches results with `CacheManager` in the configured cache directory +5. Uses discovered triggers to boost routing score for matching requests + +This is **future-proof**: new Cortex releases with additional skills work automatically. + +### Headless Execution + +Cortex is invoked with stream JSON output for non-TTY execution: +```bash +cortex -p "ENRICHED_PROMPT" --output-format stream-json +``` +Security is enforced via `--disallowed-tools` blocklists controlled by the chosen envelope. Requested envelopes are checked against `security.allowed_envelopes` before routing, approval, or Cortex execution. Auto and envelope-only modes are trusted, opt-in modes: user config cannot enable them unless an organization policy explicitly permits the relaxed field/value, `NONE` is rejected before Cortex execution, and `DEPLOY` requires explicit confirmation. + +## Real-World Example + +**Scenario:** Build a Cortex Agent for macroeconomic analysis + +``` +User: "Analyze FINANCE__ECONOMICS.

Loads Cortex capabilities from cache +2. Uses LLM reasoning to classify the request +3. Returns routing decision with confidence score + +**Routing Logic**: +- **Route to Cortex** if request involves: + - Snowflake databases, warehouses, schemas, tables + - SQL queries specifically for Snowflake + - Cortex AI features (Cortex Search, Cortex Analyst, ML functions) + - Snowpark, dynamic tables, streams, tasks + - Data governance, data quality, or security in Snowflake context + - User explicitly mentions "Cortex" or "Snowflake" + +- **Route to Claude Code** if request involves: + - Local file operations (reading, writing, editing local files) + - General programming (Python, JavaScript, etc. not Snowflake-specific) + - Non-Snowflake databases (PostgreSQL, MySQL, MongoDB, etc.) + - Web development, frontend work + - Infrastructure/DevOps unrelated to Snowflake + - Git operations, GitHub, version control + +### Step 2: Execute Based on Routing Decision + +#### If routed to Claude Code: +Handle the request directly using Claude Code's built-in capabilities. No Cortex involvement. + +#### If routed to Cortex Code: +Proceed to Step 3. + +### Step 3: Choose Security Envelope and Handle Approval + +Before executing Cortex, the security wrapper handles approval based on configured mode. + +#### Step 3a: Check Approval Mode + +Read configuration to determine approval behavior: +- **prompt mode** (default): Requires user approval +- **auto mode**: Auto-approve with audit logging +- **envelope_only mode**: Auto-approve, no tool prediction + +#### Step 3b: Handle Approval (if prompt mode) + +If using prompt mode: + +```bash +python scripts/security_wrapper.py \ + --prompt "ENRICHED_PROMPT" \ + --envelope "RW" +``` + +This will: +1.

Invokes `cortex -p "prompt" --output-format stream-json` +2. Uses print mode for prompt delivery and stream JSON output for non-TTY parsing +3. Applies envelope-based security via `--disallowed-tools` blocklist for safety +4. Parses NDJSON event stream in real-time +5. Detects tool use events and execution results + +**Key Insight**: The wrapper intentionally does not combine `-p` with `--input-format stream-json`. Cortex reserves `--input-format` for JSON stdin input; with closed stdin, that combination can emit only an init event and exit before processing the prompt. + +**Security Envelopes**: +- **RO** (Read-Only): Blocks Edit, Write, destructive Bash commands +- **RW** (Read-Write): Blocks destructive operations like rm -rf, sudo +- **RESEARCH**: Read access plus web tools, blocks write operations +- **DEPLOY**: Deployment operations, blocks destructive Bash commands +- **NONE**: Custom blocklist via --disallowed-tools parameter + +**Event Stream Handling**: +- `type: assistant` → Cortex's responses, display to user +- `type: tool_use` → Cortex is calling a tool +- `type: result` → Final outcome + +### Step 6: Handle Permission Requests + +With the security wrapper: +- **prompt mode**: User approves BEFORE execution (no mid-execution prompts) +- **auto/envelope_only modes**: Non-blocked tools execute under the configured envelope and audit policy + +The security wrapper handles permission management through: +1. **Upfront approval** (prompt mode): User approves predicted tools before execution +2. **Audit logging** (auto/envelope_only): All operations logged to `audit.log` in the skill's install directory +3. **Envelope enforcement**: Tool blocklist still enforced via `--disallowed-tools` + +### Step 7: Return Results to User + +Format Cortex's output for Claude Code context: +- Show SQL query results in readable format +- Display any generated artifacts +- Report success/failure status +- Provide relevant excerpts from Cortex's analysis + +## Examples + +### Example 1: Snowflake Query +**User says**: "Show me the top 10 customers by revenue in Snowflake" + +**Routing**: → Cortex Code (Snowflake SQL query) + +**Security Envelope**: RW (allows SQL execution) + +**Cortex Action**: +1.

Loads Cortex capabilities from cache +2. Uses LLM reasoning to classify the request +3. Returns routing decision with confidence score + +**Routing Logic**: +- **Route to Cortex** if request involves: + - Snowflake databases, warehouses, schemas, tables + - SQL queries specifically for Snowflake + - Cortex AI features (Cortex Search, Cortex Analyst, ML functions) + - Snowpark, dynamic tables, streams, tasks + - Data governance, data quality, or security in Snowflake context + - User explicitly mentions "Cortex" or "Snowflake" + +- **Route to Claude Code** if request involves: + - Local file operations (reading, writing, editing local files) + - General programming (Python, JavaScript, etc. not Snowflake-specific) + - Non-Snowflake databases (PostgreSQL, MySQL, MongoDB, etc.) + - Web development, frontend work + - Infrastructure/DevOps unrelated to Snowflake + - Git operations, GitHub, version control + +### Step 2: Execute Based on Routing Decision + +#### If routed to Claude Code: +Handle the request directly using Claude Code's built-in capabilities. No Cortex involvement. + +#### If routed to Cortex Code: +Proceed to Step 3. + +### Step 3: Choose Security Envelope and Handle Approval + +Before executing Cortex, the security wrapper handles approval based on configured mode. + +#### Step 3a: Check Approval Mode + +Read configuration to determine approval behavior: +- **auto mode** (trusted opt-in): Auto-approve with audit logging, skip to Step 4 +- **envelope_only mode**: Auto-approve, no tool prediction, skip to Step 4 +- **prompt mode**: Requires user approval, proceed to Step 3b + +**Note**: The shipped Claude Code config defaults to `approval_mode: "prompt"`. Only skip Step 3b when the user or organization policy explicitly opts into `auto` or `envelope_only`. + +#### Step 3b: Handle Approval (prompt mode only) + +**Only use this step if approval_mode is "prompt".** Otherwise skip to Step 4. + +If using prompt mode: + +```bash +python scripts/security_wrapper.py \ + --prompt "ENRICHED_PROMPT" \ + --envelope '{"mode":"RW"}' +``` + +This will: +1.

Applies envelope-based security via `--disallowed-tools` blocklist for safety +4. Parses NDJSON event stream in real-time +5. Detects tool use events and execution results + +**Key Insight**: The wrapper intentionally does not combine `-p` with `--input-format stream-json`.

Uses snowflake_sql_execute to run: `SELECT customer_name, SUM(revenue) as total FROM sales GROUP BY customer_name ORDER BY total DESC LIMIT 10` +2. Returns formatted results + +**Result**: Table displayed to user with top 10 customers. + +### Example 2: Local File Operation +**User says**: "Read the config.json file in this directory" + +**Routing**: → Claude Code (local file operation) + +**Claude Action**: Uses Read tool directly, no Cortex involvement. + +**Result**: File contents displayed. + +### Example 3: Data Quality Check +**User says**: "Check data quality for the SALES_DATA table" + +**Routing**: → Cortex Code (Snowflake data quality - matches Cortex's data-quality skill) + +**Security Envelope**: RW (allows SQL execution for analysis) + +**Cortex Action**: +1.

Core CLI is IDE-agnostic (works from any terminal) + - IDE-specific adapters generate integration files + - **Cursor adapter**: Generates `.cursor/rules/cortexcode-tool.mdc` with AI suggestions + - **VSCode adapter**: Generates `.vscode/tasks.json` + code snippets for manual invocation + - **Windsurf support**: Uses VSCode adapter (Windsurf is VSCode fork) + - Configuration controls which IDEs to support: `ide.targets: ["cursor", "vscode"]` + - Users can support multiple IDEs simultaneously + +2. **Two Approval Points (Cursor Only)** + - **Point 1:** Cursor suggests the tool (routing decision, AI-driven) + - **Point 2:** Tool shows approval prompt in terminal (authorization) + - Both serve distinct purposes: routing vs authorization + - Default: `approval_mode: "prompt"` for security + - Configurable: Users can set `approval_mode: "auto"` for speed + - Note: VSCode/Windsurf users invoke tool manually (only one approval point) + +3. **Independent Installation** + - Development: `/Users//Documents/Code/CortexCode/cortexcode-tool/` + - Installed: `~/.local/bin/cortexcode-tool` (preferred, no sudo required) or `/usr/local/bin/cortexcode-tool` + - Configuration: `~/.config/cortexcode-tool/config.yaml` + - Audit logs: `~/.config/cortexcode-tool/audit.log` + - Cache: `~/.cache/cortexcode-tool/cortex-capabilities.json` + - Cursor rules: `.cursor/rules/cortexcode-tool.mdc` (per-project) + - VSCode config: `.vscode/tasks.json` + `.vscode/cortexcode.code-snippets` (per-project) + +4. **IDE Integration Systems** + + **Cursor:** + - Supports two rule formats: + - **`.cursorrules`**: Single file in project root (simple markdown) + - **`.cursor/rules/*.mdc`**: Multiple files with frontmatter (structured, preferred) + - This tool uses `.cursor/rules/cortexcode-tool.mdc` format + - Frontmatter required: `alwaysApply: true` + - AI reads rules and suggests tool automatically + - Based on analysis of existing Cursor installations + + **VSCode/Windsurf:** + - Task Runner: `.vscode/tasks.json` for CLI invocation + - Code Snippets: `.vscode/cortexcode.code-snippets` for quick access + - User invokes manually (no AI suggestion system) + - Windsurf is VSCode fork → uses same integration method + - Optional: Settings recommendations in `.vscode/settings.json` + +5. **Code Reuse Strategy** + - Copy all Python code from `~/.claude/skills/cortex-code/` + - Adapt imports and paths for standalone use + - Maintain compatibility with cortex-code v2.0.0 security model + - No dependencies on Claude Code installation + +5. **Dynamic Capability Discovery** + - Run `cortex skill list` at startup + - Parse SKILL.md files from `~/.local/share/cortex/{version}/bundled_skills/` + - Cache discovered capabilities with SHA256 validation + - Generate .cursor/rules dynamically based on discovered triggers + - Support 35+ bundled Cortex skills automatically + +--- + +## Component Structure + +### Project Layout + +``` +/Users//Documents/Code/CortexCode/cortexcode-tool/ +├── cortexcode_tool/ +│ ├── __init__.py +│ ├── main.py # CLI entry point +│ │ +│ ├── security/ # Copied from cortex-code +│ │ ├── __init__.py +│ │ ├── approval_handler.py # Interactive approval prompts +│ │ ├── audit_logger.py # JSONL audit logging +│ │ ├── cache_manager.py # SHA256-validated caching +│ │ ├── config_manager.py # Three-layer config +│ │ └── prompt_sanitizer.py # PII removal, injection detection +│ │ +│ ├── core/ # Copied from cortex-code/scripts +│ │ ├── __init__.py +│ │ ├── route_request.py # LLM-based routing +│ │ ├── execute_cortex.py # Cortex CLI wrapper +│ │ ├── discover_cortex.py # Capability discovery +│ │ └── read_cortex_sessions.py # Session history enrichment +│ │ +│ └── ide_adapters/ # IDE-specific integrations +│ ├── __init__.py +│ ├── base_adapter.py # Base adapter interface +│ ├── cursor_adapter.py # Cursor .mdc generator +│ └── vscode_adapter.py # VSCode tasks + snippets generator +│ +├── .cursor/ +│ └── rules/ +│ └── cortexcode-tool.mdc # Auto-generated for Cursor projects +│ +├── .vscode/ +│ ├── tasks.json # Auto-generated for VSCode projects +│ └── cortexcode.code-snippets # Auto-generated for VSCode projects +│ +├── config.yaml.example # Template configuration +├── setup.sh # Installation script +├── uninstall.sh # Cleanup script +├── README.md # User documentation +├── CHANGELOG.md # Version history +├── LICENSE # Apache 2.0 +│ +└── tests/ + ├── test_routing.py + ├── test_security.py + ├── test_discovery.py + └── test_integration.py +``` + +### Component Responsibilities + +#### `main.py` -
