Environment Variables

Every environment variable DSCC reads. Citations point to the source module that consumes the value.

Variables

Variable	Purpose	File:line
`DSCC_MODEL`	Default model when `--model` is omitted	main.rs:391
`DSCC_PERMISSION_MODE`	Default permission mode	main.rs:448–452
`DSCC_API_KEY`	Generic OpenAI-compatible API key	main.rs:195–205
`DSCC_BASE_URL`	Generic OpenAI-compatible endpoint	main.rs:207–216
`ANTHROPIC_API_KEY`	Anthropic auth	api providers
`ANTHROPIC_BASE_URL`	Anthropic endpoint override	api providers
`XAI_API_KEY`	xAI / Grok auth	api providers
`XAI_BASE_URL`	xAI endpoint (default `https://api.x.ai/v1`)	api providers
`DEEPSEEK_API_KEY`	DeepSeek auth	api providers
`DEEPSEEK_BASE_URL`	DeepSeek endpoint (default `https://api.deepseek.com/v1`)	api providers
`DSCC_WEB_SEARCH_BASE_URL`	Override web-search endpoint	tools.rs `WebSearch`
`DSCC_TODO_STORE`	Path override for `TodoWrite` store	tools.rs `TodoWrite`
`DSCC_AGENT_STORE`	Path override for agent artifacts	tools.rs `Agent`
`DSCC_BUNDLED_SKILLS`	Directory of bundled skills	commands/lib.rs skill discovery

--api-key and --base-url flags set DSCC_API_KEY and DSCC_BASE_URL respectively before any other reader sees them (main.rs:195–216).
--permission-mode beats DSCC_PERMISSION_MODE; when neither is set the default is danger-full-access (main.rs:428–452).
Provider-specific keys (ANTHROPIC_API_KEY, XAI_API_KEY, DEEPSEEK_API_KEY) are consulted by their respective provider adapters only; DSCC itself never falls back across providers.
