Claude Code

Status

First-party AI provider shipped with arka-deck. Agentic chat runtime based on the official Anthropic SDK.

Field	Value
Manifest id	`claude-code`
Addon id	`claude_code` (snake_case, kept for disk compatibility)
Maturity	beta
Models	`sonnet`, `opus`, `haiku`
Authentication	OAuth (`claude --version` + OAuth flow)

SDK

The runtime uses @anthropic-ai/claude-agent-sdk (version 0.2.129). The SDK manages modes, capabilities and native Claude permissions — arka-deck adds an orchestration, memory and governance layer on top.

Surfaces

Surface	Detail
`ChatRuntime`	`providers/claude_code/runtime.ts`
`ProviderTester`	`ClaudeCodeTester` (checks `claude --version` binary, then OAuth)
Catalogue manifest	`composition/addons/provider-manifests.ts` (entry `claude-code`)
Internal modules	`providers/claude_code/internal/`

Available models

Model	Usage profile
`sonnet`	Complex tasks, reasoning, code
`opus`	Deep thinking, long analysis
`haiku`	Short tasks, classification, fast drafting

The user selects the model per instance under Settings → Providers.

Security

No plain-text API key storage — OAuth only through the claude binary (which manages its token cycle).
Runtime compatibility is tested by ClaudeCodeTester before each session.
