//! Set deployment secrets tool for the agent
//!
//! Allows the agent to set environment variables and secrets on a deployment config.
//! SECURITY: Secret values are NEVER returned in tool responses. Only key names are confirmed.
//! For secrets (is_secret=true), values are collected via terminal prompt — the LLM never sees them.

Secret values are sent securely to the backend and stored encrypted.
Values are NEVER returned in tool responses - only key names are confirmed.

The is_secret flag (default: true) controls:
- true: Value masked as "********" in UI and API responses, passed via secure terraform -var flags
- false: Value visible in UI, stored in GitOps ConfigMap

For secrets (is_secret=true): OMIT the "value" field. The user will be
prompted securely in the terminal. The value goes directly to the backend.
NEVER ask the user to type secret values in chat.

For non-secrets (is_secret=false): Include the "value" field directly.

Common secrets: DATABASE_URL, API_KEY, JWT_SECRET, REDIS_URL, etc.
Common non-secrets: NODE_ENV, PORT, LOG_LEVEL, APP_NAME, etc.

**Parameters:**
- config_id: The deployment config ID (get from deploy_service or list_deployment_configs)
- secrets: Array of {key, value?, is_secret} objects

**Prerequisites:**
- User must be authenticated via `sync-ctl auth login`
- A deployment config must exist (create one with deploy_service first)

**Example:**
Set DATABASE_URL as a secret (value omitted — prompted in terminal) and NODE_ENV as a plain env var:
```json
{
  "config_id": "config-123",
  "secrets": [
    {"key": "DATABASE_URL", "is_secret": true},
    {"key": "NODE_ENV", "value": "production", "is_secret": false}
  ]
}
```

**IMPORTANT - After setting secrets:**
- Trigger a new deployment for the secrets to take effect
- Use trigger_deployment or deploy_service with preview_only=false"#
