Here's the summary:\n\n- **Code Reuse**: No existing utilities, quiet-mode patterns, or shared output helpers exist in the codebase. The 3-line `for` + `println!` loop is the simplest correct implementation, consistent with how `json` and `all` are already handled.\n\n- **Code Quality**: Clean change. Two output-mode bools on a 4-field struct is not parameter sprawl. The quiet and json branches share no extractable logic. No leaky abstractions or stringly-typed issues. The `--quiet` taking precedence over `--json` matches `docker ps` behavior.\n\n- **Efficiency**: `scan_runs` reads slightly more data than quiet mode needs, but it's required for filtering (`--before`, `--workflow`, `--label`, `--orphans`, status filtering). This is a human-invoked CLI command over dozens of small JSON files — sub-millisecond overhead. No concurrency, memory, or hot-path concerns.\n\n**The code is already clean. No changes needed.**",

The change is minimal — a new boolean CLI arg and a simple loop printing `run_id`. No existing utilities are being duplicated. The pattern matches the existing `--json` early-return pattern already in the function.\n\n**Agent 2 (Code Quality):** No issues found. The code is clean across all five criteria. The `quiet` and `json` short-circuit pattern is natural, not copy-paste. Field placement in the struct is well-organized. `--quiet` correctly takes precedence over `--json` when both are passed.\n\n**Agent 3 (Efficiency):** No issues found. The quiet branch short-circuits before any table formatting work, which is correct. The `scan_runs` and `filter_runs` calls are necessary regardless of output mode. No unnecessary work, no memory issues, no missed concurrency opportunities.\n\n**Conclusion: The code is already clean.** The change is a minimal, well-placed 7-line addition that follows existing patterns in the codebase.
