New Features in v7.2

1. Kiro OAuth Support (HIGH PRIORITY)

What’s New:

Full OAuth support for Kiro provider (AWS Bedrock Claude)
Browser-based authentication flow
Token import from Kiro IDE

Migration Steps:

Fresh Setup
Import from IDE
Incognito Mode

# First-time Kiro setup
ccs kiro --auth

Browser opens for AWS SSO login. Authenticate and grant access.

# Import token from Kiro IDE
ccs kiro --import

Automatically imports credentials from ~/.kiro/ directory.

# config.yaml - Disable incognito for persistent AWS session
cliproxy:
  kiro_no_incognito: true

Or use the CLI flag:

ccs kiro --no-incognito

Configuration:

cliproxy:
  oauth_accounts:
    kai-work: "kai@work.com" # Kiro account
  variants:
    kiro-dev:
      provider: kiro
      account: kai-work
      settings: "~/.ccs/kiro-dev.settings.json"
  kiro_no_incognito: false # Default: false (use incognito)

CLI Flags:

Flag	Purpose
`--auth`	Authenticate via browser OAuth
`--import`	Import token from Kiro IDE
`--no-incognito`	Use normal browser mode (saves session)
`--use <account>`	Switch Kiro account
`--accounts`	List all Kiro accounts

Use Cases:

Access AWS Bedrock Claude via Kiro
Use Claude via AWS SSO with MFA
Persistent AWS session (no re-auth)

2. GHCP Device Code Flow (HIGH PRIORITY)

What’s New:

GitHub Copilot (GHCP) provider now uses Device Code flow
No headless browser required
Better support for SSH/remote environments

Migration Steps:

# Headless browser flow (deprecated)
ccs ghcp --headless
# Copy URL, open in local browser

# Device Code flow (automatic)
ccs ghcp --auth

# Output:
# Visit: https://github.com/login/device
# Enter code: ABCD-1234
# Waiting for authentication...

Configuration:

cliproxy:
  oauth_accounts:
    kai-personal: "kai@github.com"
  variants:
    ghcp-work:
      provider: ghcp
      account: kai-personal

CLI Usage:

# First-time setup
ccs ghcp --auth

# Add another GitHub account
ccs ghcp --auth --add

# Switch accounts
ccs ghcp --use work-account

# List accounts
ccs ghcp --accounts

Benefits:

Works in SSH sessions
No browser automation
More reliable auth flow
Better UX for remote development

New Features in v7.1

3. Remote CLIProxy Support (HIGH PRIORITY)

What’s New:

Connect to remote CLIProxyAPI server
Share proxy across multiple machines
Fallback to local proxy if remote unreachable

Migration Steps:

Configure Remote Proxy

cliproxy_server:
  remote:
    enabled: true
    host: "proxy.example.com"
    port: 8443 # Optional (default: 443 for HTTPS, 80 for HTTP)
    protocol: "https" # http or https
    auth_token: "your-token-123"
    management_key: "mgmt-key-456" # Optional (falls back to auth_token)
    timeout: 5000 # Optional (default: 2000ms)
  fallback:
    enabled: true # Graceful degradation
  local:
    port: 8317
    auto_start: true # Auto-start local if remote fails

Test Connection

ccs glm

This will try the remote proxy first. Check logs for connection status:

[i] Connecting to remote proxy at https://proxy.example.com:8443
[OK] Remote proxy connected

Force Remote Only

ccs codex --remote-only

Fails with PROXY_ERROR if the remote proxy is unreachable.

CLI Flags:

Flag	Purpose	Priority
`--proxy-host <host>`	Remote proxy hostname	HIGH
`--proxy-port <port>`	Remote proxy port	HIGH
`--proxy-auth-token <token>`	Remote auth token	HIGH
`--proxy-protocol <http\|https>`	Protocol (default: http)	MEDIUM
`--local-proxy`	Force local mode	MEDIUM
`--remote-only`	Fail if remote unreachable	MEDIUM
`--proxy-timeout <ms>`	Health check timeout	LOW
`--allow-self-signed`	Accept self-signed certs	LOW

Environment Variables:

export CCS_PROXY_HOST="proxy.example.com"
export CCS_PROXY_PORT="8443"
export CCS_PROXY_AUTH_TOKEN="your-token-123"
export CCS_PROXY_PROTOCOL="https"
export CCS_PROXY_FALLBACK_ENABLED="true"
export CCS_PROXY_TIMEOUT="5000"
export CCS_ALLOW_SELF_SIGNED="false"

Use Cases:

Centralized proxy for teams
Share OAuth credentials across machines
Reduce per-machine setup
Better security (credentials on server only)

Architecture:

┌─────────────┐          ┌──────────────────┐
│ Machine A   │          │                  │

                         ┌──────────────────┐
                         │  Gemini API      │
                         │  Codex API       │
                         │  Antigravity API │
                         └──────────────────┘

Security:

Use HTTPS for production
Separate management_key for admin endpoints
Rotate tokens regularly
Use firewall rules for access control

4. Proactive Token Refresh (HIGH PRIORITY)

What’s New:

Automatic token refresh 5 minutes before expiration
Prevents mid-session auth failures
Supports Gemini, Codex, Antigravity, Qwen, iFlow

Migration Steps: No action required - Automatic for all OAuth providers How It Works:

Token Expiry Check

Before each API request, CCS checks token expiration.

Proactive Refresh

If token expires in <5 minutes, refresh automatically.

Seamless Session

User experiences no interruption.

Configuration:

# No configuration needed - enabled by default
cliproxy:
  providers:
    - gemini # Auto-refresh enabled
    - codex # Auto-refresh enabled
    - agy # Auto-refresh enabled

Logging: Enable debug logs to see refresh activity:

CCS_DEBUG=1 ccs codex
# Output:
# [i] Token expires in 4m 32s, refreshing...
# [OK] Token refreshed, new expiry: 2025-12-16T15:30:00Z

Benefits:

No mid-session auth failures
Better user experience
Reduced support tickets

New Features in v6

5. Customizable Management Key (HIGH PRIORITY)

What’s New:

Separate management_key from api_key
Enhanced security for admin endpoints
Per-variant auth override

Migration from v5:

cliproxy:
  auth: "single-key-for-all"

cliproxy:
  auth:
    api_key: "ccs-internal-managed" # For API requests
    management_secret: "ccs" # For management endpoints

Configuration:

cliproxy:
  auth:
    api_key: "custom-api-key-123"
    management_secret: "custom-mgmt-secret-456"
  variants:
    my-gemini:
      provider: gemini
      auth:
        api_key: "variant-api-key"
        management_secret: "variant-mgmt-secret"

Use Cases:

Separate API vs admin credentials
Different auth per environment (dev/prod)
Enhanced security for production

6. Variant-Specific Auth (HIGH PRIORITY)

What’s New:

Per-variant auth override
Different credentials per variant
Isolate dev/prod environments

Migration Steps:

Global Auth

# Before v6 - Single auth for all variants cliproxy: auth:

"global-key" variants: codex-dev: provider: codex codex-prod: provider:
codex ```
</Tab>
<Tab title="Variant Auth">
```yaml # v6+ - Per-variant auth cliproxy: auth: api_key: "global-default"
management_secret: "global-secret" variants: codex-dev: provider: codex
auth: api_key: "dev-key" management_secret: "dev-secret" codex-prod:
provider: codex auth: api_key: "prod-key" management_secret: "prod-secret"

Use Cases:

Separate dev/prod credentials
Per-team auth keys
Testing with different API keys
Security isolation

7. Port Isolation for Variants (MEDIUM PRIORITY)

What’s New:

Assign unique ports to variants (8318-8417)
Run multiple variants concurrently
Avoid port conflicts

Migration Steps:

cliproxy:
  variants:
    codex-dev:
      provider: codex
      port: 8318 # NEW: Explicit port assignment
    codex-prod:
      provider: codex
      port: 8319 # Different port = concurrent execution
    custom-qwen:
      provider: qwen
      port: 8320

Port Range:

8317: Default local proxy (reserved)
8318-8417: Available for variants (100 ports)

Use Cases:

Run dev and prod simultaneously
Multi-user environments
Isolated testing

CLI Usage:

# Terminal 1
ccs codex-dev    # Port 8318

# Terminal 2 (concurrently)
ccs codex-prod   # Port 8319

Configuration Priority Resolution

CCS resolves configuration values in this priority order:

1. CLI Flags (highest)
   ↓
2. Environment Variables
   ↓
3. config.yaml
   ↓
4. Defaults (lowest)

Example:

ccs codex --proxy-host proxy.example.com

CCS_PROXY_HOST=proxy.example.com ccs codex

cliproxy_server:
  remote:
    host: "proxy.example.com"

Result: CLI flag overrides env var, env var overrides config file.

Multi-Account OAuth Workflow

New in v6+: Multi-account support for all OAuth providers

Add First Account

ccs codex --auth

Browser opens for authentication. The account is saved with the email as the default nickname.

Add Second Account

ccs codex --auth --add

Authenticate with a different account.

List Accounts

ccs codex --accounts

Example output:

kai@personal.com (default)
kai@work.com

Switch Account

ccs codex --use kai@work.com

Rename Account

ccs codex --nickname work-account

After renaming, switch with:

ccs codex --use work-account

Configuration:

cliproxy:
  oauth_accounts:
    personal: "kai@personal.com"
    work: "kai@work.com"
  variants:
    gemini-personal:
      provider: gemini
      account: personal # Use specific account
    gemini-work:
      provider: gemini
      account: work

CLI Flags:

Flag	Purpose
`--accounts`	List all accounts
`--use <account>`	Switch default account
`--auth`	Authenticate (current account)
`--auth --add`	Add new account
`--nickname <name>`	Rename current account
`--logout`	Clear tokens for current account
