Theme

Obsidian Prism - a dark theme built on a near-black #080909 base with translucent backgrounds and VS Code–inspired syntax highlighting.

Highlights

• AI - Claude Opus 4 (thinking) as the default agent model, with Context7 MCP tools auto-allowed
• Appearance - Bar cursor, comfortable project panel spacing, no horizontal scrollbar, Base Charmed Icons
• Privacy - Telemetry fully disabled

Rules

Three agent rules in the prompt library:

• Git Commit - Modified built-in rule enforcing Conventional Commits format (type(scope): Subject), imperative mood, 50-char subject limit, and minimal body usage
• Context7 - Caps maxTokens at 5000 when calling the query-docs MCP tool to avoid flooding the context window
• Writing Style - UK English spelling, no em dashes or emojis, minimal inline comments, and proper documentation standards per language (JSDoc, docstrings, etc.)

Anthropic model sync

update-anthropic-models.py repopulates the Anthropic model picker when Claude is routed through the CLIProxyAPI proxy.

Since zed#56397 Zed discovers Anthropic models by fetching GET {api_url}/v1/models and expects each entry to carry display_name, max_input_tokens and max_tokens. The proxy returns an OpenAI-style list without those fields, so the parse fails and the dropdown is left empty (see zed#56880). Only model discovery breaks; the inference path (/v1/messages) is unaffected.

The script reads the model ids from the proxy and writes a language_models.anthropic.available_models block into settings.json, supplying the context and output token limits from a MODEL_DEFAULTS table at the top of the file. Run it whenever the proxy exposes new models.

python3 update-anthropic-models.py            # apply
python3 update-anthropic-models.py --dry-run  # preview without writing

The proxy URL is read from the existing api_url in settings.json (override with --base-url; pass --api-key if the proxy needs auth). The generated block is fenced with marker comments, so re-runs replace it in place and leave the rest of the file untouched. A timestamped settings.json.*.bak backup is written before each change and is gitignored.
