anthropic preset (Anthropic-compatible)

Use this child for the built-in anthropic template (display "Anthropic-compatible") and for any saved preset whose provider is anthropic. anthropicPreset in tui/internal/preset/preset.go ships provider anthropic, an empty model, api_key_env ANTHROPIC_API_KEY, and base_url null, with web_search on DuckDuckGo, vision inheriting the agent's own provider, and the skills default. It is an API-key route; the Claude Code CLI login is the separate claude preset (reference/claude/SKILL.md).

Template-specific settings

• base_url — optional. Empty means the official Anthropic API (https://api.anthropic.com). Set it to any Anthropic Messages-compatible endpoint (another vendor's /anthropic route, a relay, or a local proxy). The value excludes the version path: requests go to {base_url}/v1/messages.
• api_key_env — the env-var name holding the key (default ANTHROPIC_API_KEY). Editing and saving the template stamps a fresh per-preset slot (ANTHROPIC_1_API_KEY, ...). The key is sent as x-api-key.
• model — free text. Use a model ID the configured endpoint serves: for the official API read the Anthropic models documentation (or an authenticated GET {base_url}/v1/models); for another vendor read that vendor's documentation. Save refuses an empty model.
• thinking — standard reasoning effort: none, minimal, low, medium, high, xhigh, or omitted (the kernel default); the adapter maps a level to an extended-thinking budget.

There is no wire_api or service_tier on this family. A vendor that only exposes an OpenAI-compatible endpoint uses reference/openai/SKILL.md.

TUI surfaces to revise

Start at anthropicPreset in tui/internal/preset/preset.go. In tui/internal/tui/preset_editor.go anthropic has no providerModels entry (free-text model), base_url is free text with the official endpoint shown when empty, levelThinkingOptions drives the reasoning row, and the service tier and wire rows are hidden. /doctor probes this family with GET {base_url}/v1/models (x-api-key + anthropic-version) and one max_tokens=1 Messages call (probeLLM in tui/internal/tui/doctor.go).

Reviewed deterministic revision

Prepare an evidence-bound manifest and explicit input, then run lingtai-tui presets revise --manifest PATH --input PATH --mode dry-run|check|apply [--output-dir PATH]. Review the JSON plan, use dry-run/check before apply, and apply only to a new explicit output directory. revision.go validates hashes, route bindings, and evidence and preserves unowned bytes.

Maintenance: If the relevant TUI preset/page is revised, check whether this sub-skill also needs revision and, if so, include it in the same PR.

Operations

For save, endpoint/capability, availability, activation/refresh, or troubleshooting, use the five shared operation children under reference/operations/; this child owns the Anthropic-compatible family facts, so inspect the actual saved manifest for user-owned endpoint, model, credential, and capability facts.
