GOAL
Study the archived opencode coding agent project to understand its architecture, features and philosophy, and identify high-leverage ideas that could add value to Pi without large changes.
- +0Prompt · +0Review opencode's repo (clone it locally) for overall behaviour, philosophy, specific features, comparison to Pi, and high-leverage ideas we could borrow without big changes.
- +0mAgent did · +0mCloned opencode-ai/opencode locally and walked through its Go internals: app, session, permission, history, db, tui/page/chat, and llm/agent packages, reading key files like agent.go, bash.go, permission.go, edit.go, view.go, write.go and sidebar.go.
- +1mAgent did · +1mRead Pi's own README files (top-level and packages/coding-agent) for comparison context, then reviewed opencode's prompt package (coder.go, prompt.go) and remaining tool files (patch.go, agent-tool.go, tools.go) to map out its tool surface and system prompt design.
- +2mAgent did · +2mRan a long series of targeted grep searches across both repos to verify specific behaviours: autoCompact/summarization thresholds, permission request flow, 'read before edit' enforcement, file versioning, sub-agent tool description, banned bash commands, MCP support, and Pi's own no-MCP/no-sub-agent design choices for direct comparison.
- +8mOutcome · +8mDelivered a written comparison report covering opencode's architecture snapshot, behaviour/philosophy (OpenCode.md memory file, permission gating, autoCompact at 95% context), and feature-by-feature contrast with Pi to surface candidate improvements.
VERDICT
I'd start by pointing the agent straight at the specific subsystems I care about (permissions, memory/compaction, sub-agents) instead of letting it wander the whole repo tree first — that would have gotten to the comparison faster. There were no real corrections needed here since it was a pure read-only research task; the useful part was cross-checking claims with grep across both codebases rather than trusting summaries.
