Initial development host configuration skill

Use this skill to run the full host configuration process in a repeatable way.

Activation

• This skill must be triggered manually by name: init-config-devbox.
• Do not auto-activate this skill for unrelated tasks.

Network policy

• Treat all network access as fallback.
• Prefer local assets first (scripts/, existing binaries, local config/state).
• Use network only when required inputs/tools are missing or explicitly requested.
• Proxy usage is controlled by [proxy].candidate_list from selected TOML:
  • If candidate_list is present and non-empty, use proxy-aware flow.
  • If candidate_list is missing or empty, run all installation/configuration commands without proxy setup/sourcing.

Inputs and references

• Proxy script: scripts/setup-proxy.sh
• Unified configuration file: config.toml
• Config schema: config-schema.json
• Vendored scripts: scripts/
  • Refresh vendored scripts from raw GitHub URLs (no git checkout):
    • bash scripts/sync-from-lanren-ai.sh --ref main

Configuration file selection:

• Allow user to specify an alternate TOML path (for example via prompt input or an explicit argument).
• If user does not provide a TOML path, fall back to the skill-accompanied file:
  • ./config.toml
• Validate selected TOML against ./config-schema.json before applying changes.

Required execution order

1) Setup proxy (setup-proxy.sh and .bashrc)

1. If [proxy].candidate_list is present and non-empty, use accompanied local script first:
   • install -m 0755 ./scripts/setup-proxy.sh "$HOME/setup-proxy.sh"
2. If [proxy].candidate_list is present and non-empty, ensure .bashrc contains proxy candidates in order:
   • export PROXY_CANDIDATE_LIST="<candidate_list joined by comma>"
   • Do not hardcode host-specific proxy entries in this skill; use values from TOML or existing host .bashrc.
3. For proxy-required install operations, source first only when [proxy].candidate_list is present and non-empty:
   • source ~/setup-proxy.sh
4. If [proxy].candidate_list is missing or empty, skip proxy setup/sourcing entirely.

2) Configure/install pixi

Rules:

• If [proxy].candidate_list is present and non-empty, source proxy before pixi install/update commands.
• If [proxy].candidate_list is missing or empty, run pixi commands directly without proxy sourcing.
• Use global tool install: pixi global install ...
• Read channel priority from [pixi].channel_priority in TOML (do not hardcode channels in this skill).
• If [paths].pixi_cache_dir is set and non-empty, redirect pixi/rattler cache via .bashrc:
  • export PIXI_CACHE_DIR="<pixi_cache_dir>"
  • export RATTLER_CACHE_DIR="<pixi_cache_dir>"
• If [paths].pixi_cache_dir is missing or empty, do not set PIXI_CACHE_DIR/RATTLER_CACHE_DIR; use Pixi/Rattler defaults.

Global tool set:

• Read from [pixi].global_tools in TOML (do not hardcode tool names in this skill).

Install command:

• If [proxy].candidate_list is present and non-empty:
  • source ~/setup-proxy.sh; pixi --no-progress global install <tools from [pixi].global_tools>
• If [proxy].candidate_list is missing or empty:
  • pixi --no-progress global install <tools from [pixi].global_tools>

3) Configure/install uv

Rules:

• If [proxy].candidate_list is present and non-empty, source proxy before uv install/update commands.
• If [proxy].candidate_list is missing or empty, run uv commands directly without proxy sourcing.
• Use global tool install: uv tool install ...
• If [paths].uv_cache_dir is set and non-empty, redirect uv cache via .bashrc:
  • export UV_CACHE_DIR="<uv_cache_dir>"
• If [paths].uv_cache_dir is missing or empty, do not set UV_CACHE_DIR; use uv defaults.

Global tool set:

• Read from [uv].global_tools in TOML (do not hardcode tool names in this skill).

Install commands:

• If [proxy].candidate_list is present and non-empty:
  • source ~/setup-proxy.sh; uv tool install <each tool from [uv].global_tools>
• If [proxy].candidate_list is missing or empty:
  • uv tool install <each tool from [uv].global_tools>

4) Configure/install npm (skip bootstrap if already present)

Rules:

• If npm --version succeeds, skip npm bootstrap installation.
• If [proxy].candidate_list is present and non-empty, source proxy before npm config/install operations.
• If [proxy].candidate_list is missing or empty, run npm config/install operations directly without proxy sourcing.
• Configure npm mirror from TOML:
  • npm config set registry <[urls].npm_registry_mirror>
• Install global packages with latest policy:
  • Read package list from [npm].global_packages and apply [npm].install_global / [npm].install_latest.

Note:

• If no npm global package list is explicitly provided, only set registry/config and skip global installs.

5) Configure/install bun (skip bootstrap if already present)

Rules:

• If bun --version succeeds, skip bun bootstrap installation.
• If bootstrap is needed and [proxy].candidate_list is present and non-empty, proxy may be used for bootstrap only.
• If [proxy].candidate_list is missing or empty, run bun bootstrap/install/update directly without proxy sourcing.
• Install global packages with latest policy:
  • Read package list from [bun].global_packages and apply [bun].install_global / [bun].install_latest.
• Update globals:
  • bun update -g --latest

6) Configure Claude Code

Use local vendored scripts in scripts/claude-code-cli/.

Required outcomes:

1. Skip login/onboarding enabled.
2. Custom alias launcher created (read alias from [claude].alias; do not hardcode alias in this skill).
3. Tavily MCP configured.
4. Context7 MCP configured.

Credential policy:

• Read secrets and all configurable values from the selected TOML (user-provided TOML if specified, otherwise ./config.toml).
• Do not write secrets into markdown docs.

Missing credential handling:

• For each required credential (anthropic_api_key, tavily_api_key, context7_api_key), if the TOML value is empty or missing, explicitly ask the user how to proceed.
• Offer exactly these choices per missing credential:
  1. Provide the credential value directly.
  2. Provide an environment variable name that already contains the credential.
  3. Refuse to provide it.
• If user provides a value or env reference, use it only for the current run unless the user explicitly asks to persist it.
• If user refuses to provide a credential, skip only the steps that require that credential and continue with all remaining applicable steps.
• Never block the full workflow due to one missing credential if unaffected steps can still run.

Credential-to-step mapping:

• anthropic_api_key is required for scripts/claude-code-cli/config-custom-api-key.sh.
• tavily_api_key is required for scripts/claude-code-cli/config-tavily-mcp.sh.
• context7_api_key is required only when applying Context7 API key via claude mcp add-json; scripts/claude-code-cli/config-context7-mcp.sh can still run.

Execution sequence (using vendored scripts):

• sh scripts/claude-code-cli/config-skip-login.sh
• sh scripts/claude-code-cli/config-custom-api-key.sh --alias-name <alias> --api-key <claude_api_key>
• sh scripts/claude-code-cli/config-tavily-mcp.sh --api-key <tavily_api_key>
• sh scripts/claude-code-cli/config-context7-mcp.sh
• Then ensure Context7 key is applied in MCP env via claude mcp add-json if needed.

Verification checklist

• Proxy selection works: source ~/setup-proxy.sh
• Pixi tools present: pixi global list
• uv tools present: uv tool list
• npm available and configured: npm --version and npm config get registry
• bun globals present: bun pm -g ls
• Claude onboarding skipped: ~/.claude.json contains hasCompletedOnboarding=true
• Claude MCP healthy: claude mcp list shows tavily and context7

Documentation requirements

• Keep all credentials only in the selected TOML (fallback: ./config.toml).
• Store non-secret execution notes in your current task output/logs; do not duplicate secrets in docs.
