From 5caf5020097d311cf2687c370f2956627babc9f7 Mon Sep 17 00:00:00 2001 From: vikingowl Date: Sat, 1 Nov 2025 21:59:08 +0100 Subject: [PATCH] feat(M12): complete milestone with plugins, checkpointing, and rewind MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the remaining M12 features from AGENTS.md: **Plugin System (crates/platform/plugins)** - Plugin manifest schema with plugin.json support - Plugin loader for commands, agents, skills, hooks, and MCP servers - Discovers plugins from ~/.config/owlen/plugins and .owlen/plugins - Includes comprehensive tests (4 passing) **Session Checkpointing (crates/core/agent)** - Checkpoint struct capturing session state and file diffs - CheckpointManager with snapshot, diff, save, load, and rewind capabilities - File diff tracking with before/after content - Checkpoint persistence to .owlen/checkpoints/ - Includes comprehensive tests (6 passing) **REPL Commands (crates/app/cli)** - /checkpoint - Save current session with file diffs - /checkpoints - List all saved checkpoints - /rewind - Restore session and files from checkpoint - Updated /help documentation M12 milestone now fully complete: āœ… /permissions, /status, /cost (previously implemented) āœ… Checkpointing and /rewind āœ… Plugin loader with manifest schema šŸ¤– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- Cargo.toml | 1 + crates/app/cli/src/main.rs | 72 ++++++ crates/core/agent/Cargo.toml | 1 + crates/core/agent/src/lib.rs | 5 +- crates/core/agent/src/session.rs | 196 ++++++++++++++ crates/core/agent/tests/checkpoint.rs | 210 +++++++++++++++ crates/platform/plugins/Cargo.toml | 14 + crates/platform/plugins/src/lib.rs | 354 ++++++++++++++++++++++++++ 8 files changed, 852 insertions(+), 1 deletion(-) create mode 100644 crates/core/agent/tests/checkpoint.rs create mode 100644 crates/platform/plugins/Cargo.toml create mode 100644 crates/platform/plugins/src/lib.rs diff --git a/Cargo.toml b/Cargo.toml index 7ee36e9..8f6a593 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -6,6 +6,7 @@ members = [ "crates/platform/config", "crates/platform/hooks", "crates/platform/permissions", + "crates/platform/plugins", "crates/tools/bash", "crates/tools/fs", "crates/tools/notebook", diff --git a/crates/app/cli/src/main.rs b/crates/app/cli/src/main.rs index 2d56753..85287ec 100644 --- a/crates/app/cli/src/main.rs +++ b/crates/app/cli/src/main.rs @@ -466,6 +466,9 @@ async fn main() -> Result<()> { let mut lines = stdin.lock().lines();
