Use when you need state across calls — building env vars, navigating with cd, driving REPLs (python -i, mysql, psql, node), or responding to interactive prompts (sudo password, ssh host-key confirmation, mysql connection). Teaches the prompt-sentinel exec pattern (default mode), raw I/O for REPLs (raw_send=True then read_only=True), the one-in-flight-per-session rule, and the close-or-leak-against-the-cap discipline. Bash on macOS — never zsh; explicit shell=/bin/zsh is rejected. Read before…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Persistent PTY sessions PTY sessions are how you talk to interactive programs — programs that detect a terminal (`isatty()`) and behave differently when they don't see one. Use a session when: - You need state to persist across calls (`cd`, env vars, sourced scripts) - You're driving a REPL (`python -i`, `mysql`, `psql`, `node`, `irb`) - A program demands an interactive prompt (`sudo`, `ssh`, `npm login`, `gh auth login`) For everything else, `terminal_exec` is simpler. Sessions cost more (per-session bash process, ring buffer, idle-reaping bookkeeping) and have a hard cap (`TERMINAL_TOOLS_MAX_PTY`, default 8). ## Why PTY (and not subprocess pipes) Subprocess pipes break on every interactive program. The moment a program calls `isatty()` and sees False, it disables prompts, color, line-editing, password masking, progress bars — sometimes refuses to start. PTY makes us look like a real terminal so these programs work the same as in your shell. The cost: PTY output includes terminal escape codes (cursor moves, color codes). The session captures them as-is; if you need clean text, strip ANSI escapes in your processing layer. ## Bash on macOS — by deliberate policy …

How to install
mdr add aden-hive/hive/hive.terminal-tools-pty-sessions@sha256:5842a7c281f91937The line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
