# One-shot coding agent with format-pure stdout. The app bin loads the
# gitignored root `.env` into the process environment; entry configs here are
# the composition base, while user-plane values resolve per request through
# the two providers below.

# User-settings document (`$DSH_HOME/settings.yaml`, hot-reloaded): a
# `llm-deepseek:` section there overrides the adapter entry below without a
# restart.

# Credential store: the live process environment over `$DSH_HOME/.credentials.yaml`
# (owner-only file, hot-reloaded). The adapter resolves `DEEPSEEK_API_KEY`
# through it at each request, so no key is inlined in this file.

# The DeepSeek adapter. Swap to '@deepseek-ai/dsh-llm-pi-ai' for the pi-ai-backed
# twin (a `providers` dict keyed by route; `reasoning: high` replaces
# thinking/reasoningEffort). Shipped default: full thinking at max effort on
# every request. Exact-model resolution materializes request defaults before
# the request header is logged.
