nicobailon/pi-subagents v0.12.0 on GitHub

[0.12.0] - 2026-03-31

Added git worktree isolation for parallel execution via worktree: true. Applies to top-level parallel tasks, chain steps with { parallel: [...] }, and async/background chain execution. Each parallel task gets its own temporary git worktree, and the aggregated output now includes per-task diff stats plus the directory path containing full patch files.
Added worktree.ts to manage worktree lifecycle, diff capture, patch generation, and cleanup for isolated parallel runs.
Added count: N shorthand for top-level parallel tasks and chain parallel entries so one authored task can expand into repeated identical runs without manual duplication.
Added subagent_status({ action: "list" }) to list active async runs with flattened step/member status summaries.
Added /subagents-status, a read-only overlay for active async runs plus recent completed/failed runs with per-run step details. The overlay auto-refreshes while open and preserves the selected run when possible.
Documented worktree isolation, async status surfaces, and the reorganized test layout in the README.

Consolidated tests under test/unit, test/integration, test/e2e, and test/support, replacing the old mixed root-level and test/ layout. Test scripts now target those directories explicitly.
Integration tests now use a tiny local file-based mock pi harness instead of relying on the external subprocess harness for normal subagent execution.

Loader-based tests now resolve .js → .ts imports correctly when the repository path contains spaces or other URL-escaped characters. Added a focused regression test for the custom test loader.
Worktree-isolated parallel runs now reject task-level cwd overrides that differ from the shared batch/step cwd, instead of silently ignoring them. Applies to foreground parallel runs, chain parallel steps, and async/background execution.
Worktree diff capture now includes committed, modified, and newly created files without accidentally including the synthetic node_modules symlink used inside temporary worktrees.
Worktree setup now cleans up already-created worktrees if a later worktree in the same batch fails to initialize.
Prompt-template delegated parallel responses now preserve the aggregate worktree summary text instead of dropping it when rebuilding the final delegated output.
Async status and result JSON files are now written atomically so readers do not observe partial JSON during background updates.
readStatus() now returns null only for genuinely missing files and preserves real inspect/read/parse failures with context.
Async status polling and result watching now log status/result/watcher failures instead of silently swallowing them, making background completion/debugging failures visible.
Slash-command tests now match the current live snapshot contract instead of asserting the stale pre-finalized inline state.
