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.
- AGENTS.md: design principles, enforcement hierarchy, deferred loading - agents/: brainstorm, build, orchestrator, research (auto-discovered by MCP server) - skills/: research methodology (auto-discovered by MCP server) - hooks/: pre-tool-use, post-tool-use (BFF block removed), session-start, stop, pre-compact, user-prompt-submit - frameworks/: opencode/plugin.ts (resolves hooks via import.meta.url — works as project-local or global plugin), github/hooks.json - mcp/index.ts: auto-discovers agents/*.md and skills/*.md from frontmatter (replaces hand-maintained registry); server renamed all-agents - docs/: agent-infrastructure.md (generalized), research docs (7 files), ai_architectures.md, llama-server-cuda-wsl2.md - install.sh: idempotent setup — Copilot global hooks, OpenCode global plugin + AGENTS.md + MCP entry, VS Code global MCP config
