+description: >
+  How to generate agent skills from a toolset.
+---
+
+The `skills-generate` command allows you to convert a **toolset** into an **Agent Skill**. A toolset is a collection of tools, and the generated skill will contain metadata and execution scripts for all tools within that toolset, complying with the [Agent Skill specification](https://agentskills.io/specification).
+
+## Before you begin
+
+1. Make sure you have the `toolbox` executable in your PATH.
+2. Make sure you have [Node.js](https://nodejs.org/) installed on your system.
+
+## Generating a Skill from a Toolset
+
+A skill package consists of a `SKILL.md` file (with required YAML frontmatter) and a set of Node.js scripts. Each tool defined in your toolset maps to a corresponding script in the generated Node.js scripts (`.js`) that work across different platforms (Linux, macOS, Windows).
+
+
+### Command Usage
+
+The basic syntax for the command is:
+
+```bash
+toolbox <tool-source> skills-generate \
+  --name <skill-name> \
+  --toolset <toolset-name> \
+  --description <description> \
+  --output-dir <output-directory>
+```
+
+- `<tool-source>`: Can be `--tools-file`, `--tools-files`, `--tools-folder`, and `--prebuilt`. See the [CLI Reference](../reference/cli.md) for details.
+- `--name`: Name of the generated skill.
+- `--description`: Description of the generated skill.
+- `--toolset`: (Optional) Name of the toolset to convert into a skill. If not provided, all tools will be included.
+- `--output-dir`: (Optional) Directory to output generated skills (default: "skills").
+
+{{< notice note >}}
+**Note:** The `<skill-name>` must follow the Agent Skill [naming convention](https://agentskills.io/specification): it must contain only lowercase alphanumeric characters and hyphens, cannot start or end with a hyphen, and cannot contain consecutive hyphens (e.g., `my-skill`, `data-processing`).
+{{< /notice >}}
+
+### Example: Custom Tools File
+
+1. Create a `tools.yaml` file with a toolset and some tools:
+
+   ```yaml
+   tools:
+     tool_a:
+       description: "First tool"
+       run:
+         command: "echo 'Tool A'"
+     tool_b:
+       description: "Second tool"
+       run:
+         command: "echo 'Tool B'"
+   toolsets:
+     my_toolset:
+       tools:
+         - tool_a
+         - tool_b
+   ```
+
+2. Generate the skill:
+
+   ```bash
+   toolbox --tools-file tools.yaml skills-generate \
+     --name "my-skill" \
+     --toolset "my_toolset" \
+     --description "A skill containing multiple tools" \
+     --output-dir "generated-skills"
+   ```
+
+3. The generated skill directory structure:
+
+   ```text
+   generated-skills/
+   └── my-skill/
+       ├── SKILL.md
+       ├── assets/
+       │   ├── tool_a.yaml
+       │   └── tool_b.yaml
+       └── scripts/
+           ├── tool_a.js
+           └── tool_b.js
+   ```
+
+   In this example, the skill contains two Node.js scripts (`tool_a.js` and `tool_b.js`), each mapping to a tool in the original toolset.
+
+### Example: Prebuilt Configuration
+
+You can also generate skills from prebuilt toolsets:
+
+```bash
+toolbox --prebuilt alloydb-postgres-admin skills-generate \
+  --name "alloydb-postgres-admin" \
+  --description "skill for performing administrative operations on alloydb"
+```
+
+## Installing the Generated Skill in Gemini CLI
+
+Once you have generated a skill, you can install it into the Gemini CLI using the `gemini skills install` command.
+
+### Installation Command
+
+Provide the path to the directory containing the generated skill:
+
+```bash
+gemini skills install /path/to/generated-skills/my-skill
+```
+
+Alternatively, use ~/.gemini/skills as the `--output-dir` to generate the skill straight to the Gemini CLI.

+## Requirements
+
+### Database User
+
+This source uses standard authentication. You will need to [create a CockroachDB user][crdb-users] to login to the database with. For CockroachDB Cloud deployments, SSL/TLS is required.
+
+[crdb-users]: https://www.cockroachlabs.com/docs/stable/create-user.html
+
+### SSL/TLS Configuration
+
+CockroachDB Cloud clusters require SSL/TLS connections. Use the `queryParams` section to configure SSL settings:
+
+- **For CockroachDB Cloud**: Use `sslmode: require` at minimum
+- **For self-hosted with certificates**: Use `sslmode: verify-full` with certificate paths
+- **For local development only**: Use `sslmode: disable` (not recommended for production)
+

+| `sslcert` | file path | Path to client certificate |
+| `sslkey` | file path | Path to client key |
+| `application_name` | string | Application name for connection tracking |
+
+## Best Practices
+
+### Security and MCP Compliance
+
+**Read-Only by Default**: The integration follows MCP best practices by defaulting to read-only mode. This prevents accidental data modifications:
+
+```yaml
+sources:
+  my_cockroachdb:
+    readOnlyMode: true        # Default behavior
+    enableWriteMode: false    # Explicit write opt-in required
+```
+
+To enable write operations:
+
+```yaml
+sources:
+  my_cockroachdb:
+    readOnlyMode: false       # Disable read-only protection
+    enableWriteMode: true     # Explicitly allow writes
+```
+
+**Query Limits**: Automatic row limits prevent excessive data retrieval:
+- SELECT queries automatically get `LIMIT 1000` appended (configurable via `maxRowLimit`)
+- Queries are terminated after 30 seconds (configurable via `queryTimeoutSec`)
+
+**Observability**: Structured telemetry provides visibility into tool usage:
+- Tool invocations are logged with status, latency, and row counts
+- SQL queries are redacted to protect sensitive values
+- Set `telemetryVerbose: true` for detailed JSON logs
+
+### Use UUID Primary Keys
+
+CockroachDB performs best with UUID primary keys rather than sequential integers to avoid transaction hotspots:
+
+```sql
+CREATE TABLE expenses (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  description TEXT,
+  amount DECIMAL(10,2)
+);
+```
+
+### Automatic Transaction Retry
+
+This source uses the official `cockroach-go/v2` library which provides automatic transaction retry for serialization conflicts. For write operations requiring explicit transaction control, tools can use the `ExecuteTxWithRetry` method.
+
+### Multi-Region Deployments
+
+CockroachDB supports multi-region deployments with automatic data distribution. Configure your cluster's regions and survival goals separately from the Toolbox configuration. The source will connect to any node in the cluster.
+
+### Connection Pooling
+
+The source maintains a connection pool to the CockroachDB cluster. The pool automatically handles:
+- Load balancing across cluster nodes
+- Connection retry with exponential backoff
+- Health checking of connections
+
+## Troubleshooting
+
+### SSL/TLS Errors
+
+If you encounter "server requires encryption" errors:
+
+1. For CockroachDB Cloud, ensure `sslmode` is set to `require` or higher:
+   ```yaml
+   queryParams:
+     sslmode: require
+   ```
+
+2. For certificate verification, download your cluster's root certificate and configure:
+   ```yaml
+   queryParams:
+     sslmode: verify-full
+     sslrootcert: /path/to/ca.crt
+   ```
+
+### Connection Timeouts
+
+If experiencing connection timeouts:
+
+1. Check network connectivity to the CockroachDB cluster
+2. Verify firewall rules allow connections on port 26257
+3. For CockroachDB Cloud, ensure IP allowlisting is configured
+4. Increase `maxRetries` or `retryBaseDelay` if needed
+
+### Transaction Retry Errors
+
+CockroachDB may encounter serializable transaction conflicts. The integration automatically handles these retries using the cockroach-go library. If you see retry-related errors, check:
+
+1. Database load and contention
+2. Query patterns that might cause conflicts
+3. Consider using `SELECT FOR UPDATE` for explicit locking

+  Execute ad-hoc SQL statements against a CockroachDB database.
+
+---
+
+## About
+
+A `cockroachdb-execute-sql` tool executes ad-hoc SQL statements against a CockroachDB database. This tool is designed for interactive workflows where the SQL query is provided dynamically at runtime, making it ideal for developer assistance and exploratory data analysis.
+
+The tool takes a single `sql` parameter containing the SQL statement to execute and returns the query results.
+
+> **Note:** This tool is intended for developer assistant workflows with human-in-the-loop and shouldn't be used for production agents. For production use cases with predefined queries, use [cockroachdb-sql](./cockroachdb-sql.md) instead.
+
+## Example
+
+```yaml
+sources:
+  my_cockroachdb:
+    type: cockroachdb
+    host: your-cluster.cockroachlabs.cloud
+    port: "26257"
+    user: myuser
+    password: mypassword
+    database: defaultdb
+    queryParams:
+      sslmode: require
+
+tools:
+  execute_sql:
+    type: cockroachdb-execute-sql
+    source: my_cockroachdb
+    description: Execute any SQL statement against the CockroachDB database
+```
+
+## Usage Examples

+
+## Configuration
+
+### Required Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `type` | string | Must be `cockroachdb-execute-sql` |
+| `source` | string | Name of the CockroachDB source to use |
+| `description` | string | Human-readable description for the LLM |
+
+### Optional Fields

+|-------|------|-------------|
+| `authRequired` | array | List of authentication services required |
+
+## Parameters
+
+The tool accepts a single runtime parameter:
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `sql` | string | The SQL statement to execute |
+
+## Best Practices
+
+### Use for Exploration, Not Production
+
+This tool is ideal for:
+- Interactive database exploration
+- Ad-hoc analysis and reporting
+- Debugging and troubleshooting
+- Schema inspection
+
+For production use cases, use [cockroachdb-sql](./cockroachdb-sql.md) with parameterized queries.
+
+### Be Cautious with Data Modification
+
+While this tool can execute any SQL statement, be careful with:
+- `INSERT`, `UPDATE`, `DELETE` statements
+- `DROP` or `ALTER` statements
+- Schema changes in production
+
+### Use LIMIT for Large Results
+
+Always use `LIMIT` clauses when exploring data:
+
+```sql
+SELECT * FROM large_table LIMIT 100
+```
+
+### Leverage CockroachDB's SQL Extensions
+
+CockroachDB supports PostgreSQL syntax plus extensions:
+
+```sql
+-- Show database survival goal
+SHOW SURVIVAL GOAL FROM DATABASE defaultdb;
+
+-- View zone configurations
+SHOW ZONE CONFIGURATION FOR TABLE expenses;
+
+-- Check table localities
+SHOW CREATE TABLE expenses;
+```
+
+## Error Handling
+
+The tool will return descriptive errors for:
+- **Syntax errors**: Invalid SQL syntax
+- **Permission errors**: Insufficient user privileges
+- **Connection errors**: Network or authentication issues
+- **Runtime errors**: Constraint violations, type mismatches, etc.
+
+## Security Considerations
+
+### SQL Injection Risk
+
+Since this tool executes arbitrary SQL, it should only be used with:
+- Trusted users in interactive sessions
+- Human-in-the-loop workflows
+- Development and testing environments
+
+Never expose this tool directly to end users without proper authorization controls.
+
+### Use Authentication
+
+Configure the `authRequired` field to restrict access:
+
+```yaml
+tools:
+  execute_sql:
+    type: cockroachdb-execute-sql
+    source: my_cockroachdb
+    description: Execute SQL statements
+    authRequired:
+      - my-auth-service
+```
+
+### Read-Only Users
+
+For safer exploration, create read-only database users:
+
+```sql
+CREATE USER readonly_user;
+GRANT SELECT ON DATABASE defaultdb TO readonly_user;
+```
+
+## Common Use Cases
+
+### Database Administration
+
+```sql
+-- View database size
+SELECT
+  table_name,
+  pg_size_pretty(pg_total_relation_size(table_name::regclass)) AS size
+FROM information_schema.tables
+WHERE table_schema = 'public'
+ORDER BY pg_total_relation_size(table_name::regclass) DESC;
+```
+
+### Performance Analysis
+
+```sql
+-- Find slow queries
+SELECT query, count, mean_latency
+FROM crdb_internal.statement_statistics
+WHERE mean_latency > INTERVAL '1 second'
+ORDER BY mean_latency DESC
+LIMIT 10;
+```
+
+### Data Quality Checks
+
+```sql
+-- Find NULL values
+SELECT COUNT(*) as null_count
+FROM expenses
+WHERE description IS NULL OR amount IS NULL;
+
+-- Find duplicates
+SELECT user_id, email, COUNT(*) as count
+FROM users
+GROUP BY user_id, email
+HAVING COUNT(*) > 1;
+```

+|-------|------|-------------|
+| `authRequired` | array | List of authentication services required |
+
+## Output Structure
+
+The tool returns a list of schemas with the following information:
+
+```json
+[
+  {
+    "catalog_name": "defaultdb",
+    "schema_name": "public",
+    "is_user_defined": true
+  },
+  {
+    "catalog_name": "defaultdb",
+    "schema_name": "analytics",
+    "is_user_defined": true
+  }
+]
+```
+
+### Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `catalog_name` | string | The database (catalog) name |
+| `schema_name` | string | The schema name |
+| `is_user_defined` | boolean | Whether this is a user-created schema (excludes system schemas) |
+
+## Usage Example
+
+```json
+{}
+```
+
+No parameters are required. The tool automatically lists all user-defined schemas.
+
+## Default Schemas
+
+CockroachDB includes several standard schemas:
+
+- **`public`**: The default schema for user objects
+- **`pg_catalog`**: PostgreSQL system catalog (excluded from results)
+- **`information_schema`**: SQL standard metadata views (excluded from results)
+- **`crdb_internal`**: CockroachDB internal metadata (excluded from results)
+- **`pg_extension`**: PostgreSQL extension objects (excluded from results)
+
+The tool filters out system schemas and only returns user-defined schemas.
+
+## Schema Management in CockroachDB
+
+### Creating Schemas
+
+```sql
+CREATE SCHEMA analytics;
+```
+
+### Using Schemas
+
+```sql
+-- Create table in specific schema
+CREATE TABLE analytics.revenue (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  amount DECIMAL(10,2),
+  date DATE
+);
+
+-- Query from specific schema
+SELECT * FROM analytics.revenue;
+```
+
+### Schema Search Path
+
+The search path determines which schemas are searched for unqualified object names:
+
+```sql
+-- Show current search path
+SHOW search_path;
+
+-- Set search path
+SET search_path = analytics, public;
+```
+
+## Multi-Tenant Applications
+
+Schemas are commonly used for multi-tenant applications:
+
+```sql
+-- Create schema per tenant
+CREATE SCHEMA tenant_acme;
+CREATE SCHEMA tenant_globex;
+
+-- Create same table structure in each schema
+CREATE TABLE tenant_acme.orders (...);
+CREATE TABLE tenant_globex.orders (...);
+```
+
+The `cockroachdb-list-schemas` tool helps discover all tenant schemas:
+
+```yaml
+tools:
+  list_tenants:
+    type: cockroachdb-list-schemas
+    source: my_cockroachdb
+    description: |
+      List all tenant schemas in the database.
+      Each schema represents a separate tenant's data namespace.
+```
+
+## Best Practices
+
+### Use Schemas for Organization
+
+Group related tables into schemas:
+
+```sql
+CREATE SCHEMA sales;
+CREATE SCHEMA inventory;
+CREATE SCHEMA hr;
+
+CREATE TABLE sales.orders (...);
+CREATE TABLE inventory.products (...);
+CREATE TABLE hr.employees (...);
+```
+
+### Schema Naming Conventions
+
+Use clear, descriptive schema names:
+- Lowercase names
+- Use underscores for multi-word names
+- Avoid reserved keywords
+- Use prefixes for grouped schemas (e.g., `tenant_`, `app_`)
+
+### Schema-Level Permissions
+
+Schemas enable fine-grained access control:
+
+```sql
+-- Grant access to specific schema
+GRANT USAGE ON SCHEMA analytics TO analyst_role;
+GRANT SELECT ON ALL TABLES IN SCHEMA analytics TO analyst_role;
+
+-- Revoke access
+REVOKE ALL ON SCHEMA hr FROM public;
+```
+
+## Integration with Other Tools
+
+### Combined with List Tables
+
+```yaml
+tools:
+  list_schemas:
+    type: cockroachdb-list-schemas
+    source: my_cockroachdb
+    description: List all schemas first
+    
+  list_tables:
+    type: cockroachdb-list-tables
+    source: my_cockroachdb
+    description: |
+      List tables in the database.
+      Use list_schemas first to understand schema organization.
+```
+
+### Schema Discovery Workflow
+
+1. Call `cockroachdb-list-schemas` to discover schemas
+2. Call `cockroachdb-list-tables` to see tables in each schema
+3. Generate queries using fully qualified names: `schema.table`
+
+## Common Use Cases
+
+### Discover Database Structure
+
+```yaml
+tools:
+  discover_schemas:
+    type: cockroachdb-list-schemas
+    source: my_cockroachdb
+    description: |
+      Discover how the database is organized into schemas.
+      Use this to understand the logical grouping of tables.
+```
+
+### Multi-Tenant Analysis
+
+```yaml
+tools:
+  list_tenant_schemas:
+    type: cockroachdb-list-schemas
+    source: my_cockroachdb
+    description: |
+      List all tenant schemas (each tenant has their own schema).
+      Schema names follow the pattern: tenant_<company_name>
+```
+
+### Schema Migration Planning
+
+```yaml
+tools:
+  audit_schemas:
+    type: cockroachdb-list-schemas
+    source: my_cockroachdb
+    description: |
+      Audit existing schemas before migration.
+      Identifies all schemas that need to be migrated.
+```
+
+## Error Handling
+
+The tool handles common errors:
+- **Connection errors**: Returns connection failure details
+- **Permission errors**: Returns error if user lacks USAGE privilege
+- **Empty results**: Returns empty array if no user schemas exist
+
+## Permissions Required
+
+To list schemas, the user needs:
+- `CONNECT` privilege on the database
+- No specific schema privileges required for listing
+
+To query objects within schemas, the user needs:
+- `USAGE` privilege on the schema
+- Appropriate object privileges (SELECT, INSERT, etc.)
+
+## CockroachDB-Specific Features
+
+### System Schemas
+
+CockroachDB includes PostgreSQL-compatible system schemas plus CockroachDB-specific ones:
+
+- `crdb_internal.*`: CockroachDB internal metadata and statistics
+- `pg_catalog.*`: PostgreSQL system catalog
+- `information_schema.*`: SQL standard information schema
+
+These are automatically filtered from the results.
+
+### User-Defined Flag
+
+The `is_user_defined` field helps distinguish:
+- `true`: User-created schemas
+- `false`: System schemas (already filtered out)

+}
+```
+
+## CockroachDB-Specific Information
+
+### UUID Primary Keys
+
+The tool recognizes CockroachDB's recommended UUID primary key pattern:
+
+```sql
+CREATE TABLE users (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  ...
+);
+```
+
+### Multi-Region Tables
+
+For multi-region tables, the output includes locality information:
+
+```json
+{
+  "table_name": "users",
+  "locality": "REGIONAL BY ROW",
+  "regions": ["us-east-1", "us-west-2", "eu-west-1"]
+}
+```
+
+### Interleaved Tables
+
+The tool shows parent-child relationships for interleaved tables (legacy feature):
+
+```json
+{
+  "table_name": "order_items",
+  "interleaved_in": "orders"
+}
+```
+
+## Best Practices
+
+### Use for Schema Discovery
+
+The tool is ideal for helping AI assistants understand your database structure:
+
+```yaml
+tools:
+  discover_schema:
+    type: cockroachdb-list-tables
+    source: my_cockroachdb
+    description: |
+      Use this tool first to understand the database schema before generating queries.
+      It shows all tables, their columns, data types, and relationships.
+```
+
+### Filter Large Schemas
+
+For databases with many tables, specify relevant tables:
+
+```json
+{
+  "table_names": ["users", "orders", "products"],
+  "output_format": "detailed"
+}
+```
+
+### Use Simple Format for Overviews
+
+When you need just table names and sizes:
+
+```json
+{
+  "output_format": "simple"
+}
+```
+
+## Excluded Tables
+
+The tool automatically excludes system tables and schemas:
+- `pg_catalog.*` - PostgreSQL system catalog
+- `information_schema.*` - SQL standard information schema
+- `crdb_internal.*` - CockroachDB internal tables
+- `pg_extension.*` - PostgreSQL extension tables
+
+Only user-created tables in the public schema (and other user schemas) are returned.
+
+## Error Handling
+
+The tool handles common errors:
+- **Table not found**: Returns empty result for non-existent tables
+- **Permission errors**: Returns error if user lacks SELECT privileges
+- **Connection errors**: Returns connection failure details
+
+## Integration with AI Assistants
+
+### Prompt Example
+
+```yaml
+tools:
+  list_tables:
+    type: cockroachdb-list-tables
+    source: my_cockroachdb
+    description: |
+      Lists all tables in the database with detailed schema information.
+      Use this tool to understand:
+      - What tables exist
+      - What columns each table has
+      - Data types and constraints
+      - Relationships between tables (foreign keys)
+      - Available indexes
+      
+      Always call this tool before generating SQL queries to ensure
+      you use correct table and column names.
+```
+
+## Common Use Cases
+
+### Generate Context for Queries
+
+```json
+{}
+```
+
+This provides comprehensive schema information that helps AI assistants generate accurate SQL queries.
+
+### Analyze Table Structure
+
+```json
+{
+  "table_names": ["users"],
+  "output_format": "detailed"
+}
+```
+
+Perfect for understanding a specific table's structure, constraints, and relationships.
+
+### Quick Schema Overview
+
+```json
+{
+  "output_format": "simple"
+}
+```
+
+Gets a quick list of tables with basic statistics.
+
+## Performance Considerations
+
+- **Simple format** is faster for large databases
+- **Detailed format** queries system tables extensively
+- Specifying `table_names` reduces query time
+- Results are fetched in a single query for efficiency

+  Execute parameterized SQL queries in CockroachDB.
+
+---
+
+## About
+
+The `cockroachdb-sql` tool allows you to execute parameterized SQL queries against a CockroachDB database. This tool supports prepared statements with parameter binding, template parameters for dynamic query construction, and automatic transaction retry for resilience against serialization conflicts.
+
+## Example
+
+```yaml
+sources:
+  my_cockroachdb:
+    type: cockroachdb
+    host: your-cluster.cockroachlabs.cloud
+    port: "26257"
+    user: myuser
+    password: mypassword
+    database: defaultdb
+    queryParams:
+      sslmode: require
+
+tools:
+  get_user_orders:
+    type: cockroachdb-sql
+    source: my_cockroachdb
+    description: Get all orders for a specific user
+    statement: |
+      SELECT o.id, o.order_date, o.total_amount, o.status
+      FROM orders o
+      WHERE o.user_id = $1
+      ORDER BY o.order_date DESC
+    parameters:
+      - name: user_id
+        type: string
+        description: The UUID of the user
+```
+
+## Configuration
+
+### Required Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `type` | string | Must be `cockroachdb-sql` |
+| `source` | string | Name of the CockroachDB source to use |
+| `description` | string | Human-readable description of what the tool does |
+| `statement` | string | The SQL query to execute |
+
+### Optional Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `parameters` | array | List of parameter definitions for the query |
+| `templateParameters` | array | List of template parameters for dynamic query construction |
+| `authRequired` | array | List of authentication services required |
+
+## Parameters
+
+Parameters allow you to safely pass values into your SQL queries using prepared statements. CockroachDB uses PostgreSQL-style parameter placeholders: `$1`, `$2`, etc.
+
+### Parameter Types
+
+- `string`: Text values
+- `number`: Numeric values (integers or decimals)
+- `boolean`: True/false values
+- `array`: Array of values
+
+### Example with Multiple Parameters
+
+```yaml
+tools:
+  filter_expenses:
+    type: cockroachdb-sql
+    source: my_cockroachdb
+    description: Filter expenses by category and date range
+    statement: |
+      SELECT id, description, amount, category, expense_date
+      FROM expenses
+      WHERE user_id = $1
+        AND category = $2
+        AND expense_date >= $3
+        AND expense_date <= $4
+      ORDER BY expense_date DESC
+    parameters:
+      - name: user_id
+        type: string
+        description: The user's UUID
+      - name: category
+        type: string
+        description: Expense category (e.g., "Food", "Transport")
+      - name: start_date
+        type: string
+        description: Start date in YYYY-MM-DD format
+      - name: end_date
+        type: string
+        description: End date in YYYY-MM-DD format
+```
+
+## Template Parameters
+
+Template parameters enable dynamic query construction by replacing placeholders in the SQL statement before parameter binding. This is useful for dynamic table names, column names, or query structure.
+
+### Example with Template Parameters
+
+```yaml
+tools:
+  get_column_data:
+    type: cockroachdb-sql
+    source: my_cockroachdb
+    description: Get data from a specific column
+    statement: |
+      SELECT {{column_name}}
+      FROM {{table_name}}
+      WHERE user_id = $1
+      LIMIT 100
+    templateParameters:
+      - name: table_name
+        type: string
+        description: The table to query
+      - name: column_name
+        type: string
+        description: The column to retrieve
+    parameters:
+      - name: user_id
+        type: string
+        description: The user's UUID
+```
+
+## Best Practices
+
+### Use UUID Primary Keys
+
+CockroachDB performs best with UUID primary keys to avoid transaction hotspots:
+
+```sql
+CREATE TABLE orders (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  user_id UUID NOT NULL,
+  order_date TIMESTAMP DEFAULT now(),
+  total_amount DECIMAL(10,2)
+);
+```
+
+### Use Indexes for Performance
+
+Create indexes on frequently queried columns:
+
+```sql
+CREATE INDEX idx_orders_user_id ON orders(user_id);
+CREATE INDEX idx_orders_date ON orders(order_date DESC);
+```
+
+### Use JOINs Efficiently
+
+CockroachDB supports standard SQL JOINs. Keep joins efficient by:
+- Adding appropriate indexes
+- Using UUIDs for foreign keys
+- Limiting result sets with WHERE clauses
+
+```yaml
+tools:
+  get_user_with_orders:
+    type: cockroachdb-sql
+    source: my_cockroachdb
+    description: Get user details with their recent orders
+    statement: |
+      SELECT u.name, u.email, o.id as order_id, o.order_date, o.total_amount
+      FROM users u
+      LEFT JOIN orders o ON u.id = o.user_id
+      WHERE u.id = $1
+      ORDER BY o.order_date DESC
+      LIMIT 10
+    parameters:
+      - name: user_id
+        type: string
+        description: The user's UUID
+```
+
+### Handle NULL Values
+
+Use COALESCE or NULL checks when dealing with nullable columns:
+
+```sql
+SELECT id, description, COALESCE(notes, 'No notes') as notes
+FROM expenses
+WHERE user_id = $1
+```
+
+## Error Handling
+
+The tool automatically handles:
+- **Connection errors**: Retried with exponential backoff
+- **Serialization conflicts**: Automatically retried using cockroach-go library
+- **Invalid parameters**: Returns descriptive error messages
+- **SQL syntax errors**: Returns database error details
+
+## Advanced Usage
+
+### Aggregations
+
+```yaml
+tools:
+  expense_summary:
+    type: cockroachdb-sql
+    source: my_cockroachdb
+    description: Get expense summary by category for a user
+    statement: |
+      SELECT 
+        category,
+        COUNT(*) as count,
+        SUM(amount) as total_amount,
+        AVG(amount) as avg_amount
+      FROM expenses
+      WHERE user_id = $1
+        AND expense_date >= $2
+      GROUP BY category
+      ORDER BY total_amount DESC
+    parameters:
+      - name: user_id
+        type: string
+        description: The user's UUID
+      - name: start_date
+        type: string
+        description: Start date in YYYY-MM-DD format
+```
+
+### Window Functions
+
+```yaml
+tools:
+  running_total:
+    type: cockroachdb-sql
+    source: my_cockroachdb
+    description: Get running total of expenses

+      SELECT 
+        expense_date,
+        amount,
+        SUM(amount) OVER (ORDER BY expense_date) as running_total
+      FROM expenses
+      WHERE user_id = $1
+      ORDER BY expense_date
+    parameters:
+      - name: user_id
+        type: string
+        description: The user's UUID
+```

+          user_id,
+          SUM(amount) as total_spent
+        FROM expenses
+        WHERE expense_date >= $1
+        GROUP BY user_id
+      )
+      SELECT 
+        u.name,
+        u.email,

+## About
+
+A "looker-validate-project" tool checks the syntax of a LookML project and reports any errors
+
+It's compatible with the following sources:
+
+- [looker](../../sources/looker.md)
+
+`looker-validate-project` accepts a project_id parameter.
+
+## Example
+
+```yaml
+tools:
+    validate_project:
+        kind: looker-validate-project
+        source: looker-source
+        description: |
+          This tool checks a LookML project for syntax errors.
+
+          Prerequisite: The Looker session must be in Development Mode. Use `dev_mode: true` first.

+description: >
+  Intercept and modify interactions between the agent and its tools either before or after a tool is executed.
+---
+
+Pre- and post- processing allow developers to intercept and modify interactions between the agent and its tools or the user.
+
+{{< notice note >}}
+
+These capabilities are typically features of **orchestration frameworks** (like LangChain, LangGraph, or Agent Builder) rather than the Toolbox SDK itself. However, Toolbox tools are designed to fully leverage these framework capabilities to support robust, secure, and compliant agent architectures.
+
+{{< /notice >}}
+
+## Types of Processing
+
+### Pre-processing
+
+Pre-processing occurs before a tool is executed or an agent processes a message. Key types include:
+
+- **Input Sanitization & Redaction**: Detecting and masking sensitive information (like PII) in user queries or tool arguments to prevent it from being logged or sent to unauthorized systems.
+- **Business Logic Validation**: Verifying that the proposed action complies with business rules (e.g., ensuring a requested hotel stay does not exceed 14 days, or checking if a user has sufficient permission).
+- **Security Guardrails**: Analyzing inputs for potential prompt injection attacks or malicious payloads.
+
+### Post-processing
+
+Post-processing occurs after a tool has executed or the model has generated a response. Key types include:
+
+- **Response Enrichment**: Injecting additional data into the tool output that wasn't part of the raw API response (e.g., calculating loyalty points earned based on the booking value).
+- **Output Formatting**: Transforming raw data (like JSON or XML) into a more human-readable or model-friendly format to improve the agent's understanding.
+- **Compliance Auditing**: Logging the final outcome of transactions, including the original request and the result, to a secure audit trail.
+
+## Processing Scopes
+
+While processing logic can be applied at various levels (Agent, Model, Tool), this guide primarily focuses on **Tool Level** processing, which is most relevant for granular control over tool execution.
+
+### Tool Level (Primary Focus)
+
+Wraps individual tool executions. This is best for logic specific to a single tool or a set of tools.
+
+- **Scope**: Intercepts the raw inputs (arguments) to a tool and its outputs.
+- **Use Cases**: Argument validation, output formatting, specific privacy rules for sensitive tools.
+
+### Other Levels
+
+It is helpful to understand how tool-level processing differs from other scopes:
+
+- **Model Level**: Intercepts individual calls to the LLM (prompts and responses). Unlike tool-level, this applies globally to all text sent/received, making it better for global PII redaction or token tracking.
+- **Agent Level**: Wraps the high-level execution loop (e.g., a "turn" in the conversation). Unlike tool-level, this envelopes the entire turn (user input to final response), making it suitable for session management or end-to-end auditing.
+

+  How to add pre- and post- processing to your Agents using Python.
+---
+
+## Prerequisites
+
+This tutorial assumes that you have set up Toolbox with a basic agent as described in the [local quickstart](../../getting-started/local_quickstart.md).
+
+This guide demonstrates how to implement these patterns in your Toolbox applications.
+
+## Implementation
+
+{{< tabpane persist=header >}}
+{{% tab header="ADK" text=true %}}
+Coming soon.
+{{% /tab %}}
+{{% tab header="Langchain" text=true %}}
+The following example demonstrates how to use `ToolboxClient` with LangChain's middleware to implement pre- and post- processing for tool calls.
+
+```py
+{{< include "python/langchain/agent.py" >}}
+```
+
+You can also add model-level (`wrap_model`) and agent-level (`before_agent`, `after_agent`) hooks to intercept messages at different stages of the execution loop. See the [LangChain Middleware documentation](https://docs.langchain.com/oss/python/langchain/middleware/custom#wrap-style-hooks) for details on these additional hook types.
+{{% /tab %}}
+{{< /tabpane >}}
+
+## Results
+
+The output should look similar to the following. Note that exact responses may vary due to the non-deterministic nature of LLMs and differences between orchestration frameworks.
+
+```
+AI: Booking Confirmed! You earned 500 Loyalty Points with this stay.
+
+AI: Error: Maximum stay duration is 14 days.
