# Per-agent skill scoping. Skills are loaded on-demand by opencode: only a skill's one-line
# `description` ever appears in an agent's <available_skills> list, and the full SKILL.md body
# (curl/API how-to) is loaded ONLY when the agent calls the `skill` tool — it is never in any
# system prompt. To also hide the summary from agents that shouldn't use a skill, we deny all
# skills by default and allow only the ones in this agent's registry list (passed via $SKILLS).
# A denied skill is hidden entirely (name + description omitted), so e.g. @junior never sees
# gitea-api at all; it just knows from the roster that @senior/@lead can, and asks them.

# Three OpenAI-compatible providers: local self-hosted ollama (ornith) + Ollama Cloud
# (gemma4/kimi-k2.7-code/glm-5.2/minimax-m3) + xAI (grok-4.5). The provider `models:` maps are
# DERIVED from agents.json (the single source of truth, shared with route.sh) so every model an
# agent is routed to is always declared in the provider config. `ollama-cloud/` prefix models go to
# the cloud provider; `ollama/` prefix models go to the local provider; `xai-oc/` prefix models go
# to our xAI shim (OpenAI-compatible, https://api.x.ai/v1). No other built-in providers remain.
#
# The provider key is `xai-oc`, NOT `xai` — opencode ships a built-in `xai` entry in its own model
# catalog (a real @ai-sdk/xai integration that implements the Responses API). Naming our custom
# openai-compatible shim `xai` collides with that catalog entry: opencode's --auto permission-check
# path then assumes the catalog's provider (which has `.responses()`) and crashes with
# "Z.responses is not a function" on every run once a `permission` block is present (i.e. always in
# this pipeline). Confirmed by reproducing locally with the production config shape on opencode
# 1.17.13 — renaming the key to `xai-oc` avoids the collision entirely. See issue #118.
# See issue #31.
