Intercepts bash tool calls, detects background processes via AST parsing (@aliou/sh), and rewrites commands to redirect output to temp log files and disown. Compound commands (&&, ||, pipelines) are wrapped in braces so the redirect applies to the entire background subshell. The agent sees PID, label, and log path in the tool output, and can use cat/kill to monitor or stop background processes.
- Compound commands now ALWAYS wrap in braces, even when inner commands have redirects. Inner redirects only affect individual commands, not the background subshell that holds the pipe fds open. - State machine now tracks backtick nesting to avoid finding & inside command substitutions. - Fully-redirected simple commands no longer report a nonexistent log file in the echo output. - Removed dead echoes variable in rewriteCommand. - Added tests for isCompound detection, compound+redirect wrapping, echo output with/without log paths, backtick handling.

Makes
command &work in pi's bash tool by intercepting bash tool calls, detecting background processes via AST parsing, and rewriting commands to detach them from pipes.How it works
@aliou/shto findbackground: truestatements{ ...; }so the redirect applies to the entire background subshelldisownto detach from job control (skipped if already present)What the agent sees
72 tests covering detection, rewriting, and integration (verifying rewritten commands actually return without hanging).
