MCP tools don't populate output.output in the tool.execute.after hook —
the MCP content flows through OpenCode's internal parts pipeline instead.
This caused a crash: undefined is not an object (evaluating 'text.length')
in the truncate function.
- Add forbidden pattern: using experimental.chat.system.transform for
session-start injection causes Jinja 'System message must be at the
beginning' on Qwen-family GGUF models when orchestrator spawns subagents
- Add note to session-start.sh section explaining OpenCode delivery via
output.parts.unshift() on first chat.message turn (not system.transform)
install.sh step 3 now symlinks all agent .md files into
~/.config/opencode/agents/ so project repos no longer need
per-project .opencode/agents/ symlinks.
AGENTS.md: add anti-pattern rule — do not assert a third-party tool
lacks a feature without fetching the tool's current docs first.
