 - **`process`**: `run_argv` (argv, no shell, timeout, optional stdin/env); `run_argv_batch` (serial steps, `pipe_out` on provider, `mix_stderr`, `stop_on_error`); PTY `open_pty` / `read_pty` / `write_pty` (literal) / `write_pty_keys` (escapes) / `ask_into_pty` (human→PTY only; `secret` no-echo; answer never in tool result) / `close_pty` (POSIX: `pty`+`fork`; Windows: ConPTY via `pywinpty` env marker dep).
 - PTY: backend in `pty_backend.py`; structured status (`alive`/`exit_code`/`data`); `read_pty(..., until=)` (**CSI sanitized** so host TTY is never reset); keys via `write_pty_keys` only (`\xHH`, `ctrl+x`, `key=esc`); secrets via `ask_into_pty` (not `write_pty` data); session limit/idle TTL/output budget; close terminate→kill.
 - CLI limit hooks: interactive confirm to raise tool-loop rounds, PTY session cap, or PTY output budget. The prompt accepts `y`/empty (once), `n`, or `yyy` = stop asking for the rest of the turn (`cli.limits` module flag, reset by `run_turn_with_retries`, `/btw`, session switches, and chat exit). `--auto-continue` / `[agent] auto_continue_limits` set the process-wide default (covers one-shot/PTY); the flag does not imply YOLO and vice versa.
-- Destructive confirms: `classify_danger` + `ToolRegistry(on_confirm=…)`; CLI default deny; config `confirm_destructive` / `path_denylist`. Soft confirm also for interpreters — bare shells/REPLs, scripts, and `-c` one-liners alike (`-c` is code only for an interpreter, so `grep -c` / `od -c` stay unflagged; argv + code preview) —, detached runners (`nohup`), and wrapper options that carry a command line (`env -S "…"`, `su -c "…"`, whose text is printed under its own `env -S:` label), each resolved past env wrappers and `<launcher> run`; deny may include a user comment for the model. Session YOLO: `/yolo on|off|once` and `--yes` (skip soft confirms; hard denylists unchanged; `once` expires after the next user turn).

Soft confirm also for interpreters — bare shells/REPLs, scripts, and `-c` one-liners alike (`-c` is code only for an interpreter, so `grep -c` / `od -c` stay unflagged; argv + code preview) —, detached runners (`nohup`), and wrapper options that carry a command line (`env -S "…"`, `su -c "…"`, whose text is printed under its own `env -S:` label), each resolved past env wrappers and `<launcher> run`; deny may include a user comment for the model. Session YOLO: `/yolo on|off|once` and `--yes` (skip soft confirms; hard denylists unchanged; `once` expires after the next user turn). A round of tool calls asks **once**: `ToolRegistry.prepare_batch_confirm` pre-scans it (unknown tools, undecodable arguments, and calls missing a required argument are left out — nobody is asked about a call that cannot run), two or more soft reasons collapse into one `ToolBatchConfirmHook` prompt whose `BatchConfirmDecision` `execute(..., decision=…)` applies to each call (CLI box lists every call: `y` = allow these, `m` = review them one at a time through the per-call prompt, `N` = deny with one comment shared by all), the answer covers that round only (the next one asks again), and a lone request keeps the plain one-call prompt.
 - **`vcs`**: read-only VCS tools (`vcs_kind` / `vcs_status` / `vcs_diff` / `vcs_log` / `vcs_branch`) via `VcsBackend` protocol; **git** implemented; detectors are pluggable for other systems.
 - **`chat`**: human prompts as tools — `ask_user_line` / `ask_user_choice` / `ask_user_form` (shared `prompting` core); `wait` (line prompt with timeout; Enter disturbs). Container args are shape-checked (`tools/chat/shape.py`): a mis-typed string `options`/`fields` (or a non-string `question`) returns an explained error — `options="a, b"` used to iterate characters into a per-character menu. `wait`'s `duration` accepts numeric strings (`"5"` = 5s) and rejects booleans/text/containers.
 - **`todo`**: LIFO stack of **task groups** (not a queue of tasks) — `todo_push` creates one group of siblings; `todo_pop` removes the whole top group; `todo_update` by the number a listing shows (render order, TOP group first; the stored `id` stays internal); DFS breakdown push[T1,T2]→push[T1.1…]→pop→push[T2.1…]; stored on session row; open items = unfinished work (`[TODO OPEN WORK]`); all-terminal non-empty = hygiene (`[TODO HYGIENE]`); nag channel via `[agent] todo_nag_strategy` (`developer`/`user` = prose nag; `synthetic_tool` = forged `todo_list` call + **real** `stack.render()` result + ToolCall/Result events; `none`).
