[1.0.1] - 2026-06-26

Agent registry browser. siGit: Browse Agent Registry and siGit: Refresh Agent Registry fetch an ACP agent catalog (set the source with sigit.registry.url), keep the last good copy for offline use, and install a chosen agent by writing its launch command into sigit.agents. Install here means register the command; siGit does not download or run agent binaries for you.

Agent failed to launch with spawn sigit ENOENT when VS Code was started from the GUI (Dock, Finder, Spotlight). GUI launches inherit a minimal system PATH that omits common install dirs (Homebrew, Cargo, ~/.local/bin, and so on), so the sigit binary couldn't be found even when installed. The agent command is now resolved against an augmented PATH that adds those dirs plus the user's login-shell PATH.
A missing agent binary now shows an actionable error with Open Settings and Install Guide actions instead of a raw ENOENT, and no longer leaves the chat stuck on a hanging request.
Model load failed with Operation not permitted (os error 1) (EPERM) when the agent ran outside the Onde Inference app. The sigit agent redirects its HuggingFace cache into a macOS App Group container that only entitled, app-sandboxed processes may write to; a sigit spawned by VS Code has no such entitlement. The extension now passes writable HF_HOME / HF_HUB_CACHE defaults (~/.cache/huggingface) so model downloads land in a directory the editor's child process can write to. A real HF_HOME/HF_HUB_CACHE env var or an agent env entry still takes precedence.

Tool calls now stream in place. A tool_call and its tool_call_updates share a toolCallId and update one row with a progress bar, instead of adding a new bubble per update. Model-download progress used to stack as separate "Downloading 0%", "50%", and "failed" lines; now it stays on one row.
Packaging excludes .claude/ and lockfiles from the VSIX, so the bundle is smaller and stray worktree copies no longer get shipped.

Initial release: ACP (Agent Client Protocol) client extension for siGit Code.
On-device sigit agent as the local-first default.
JSON-RPC 2.0 peer over newline-delimited JSON for ACP transport.
ACP handshake (initialize → session/new → session/prompt) with streaming session/update notifications (message, thought, and tool-call chunks).
Inbound agent requests: session/request_permission, fs/read_text_file, fs/write_text_file.
Webview chat view in the Activity Bar with streaming output.
Agent registry (sigit.agents) and permission modes (prompt/allow/deny).
Commands: open chat, new session, select agent, restart agent.
