tool-bash-persistent overwrote the backend's PS1, so terminal-bash prompt readiness never matched and every send degraded to the 3.5s silence tier (idleSilenceMs + handoffGraceMs) under production defaults. The controlled PROMPT_COMMAND now re-asserts PS1 before every prompt, so an in-shell override never survives to the next prompt. The tool initializes with stty -echo alone and detects the no-end-marker fallback through the seam's stdin_read wait reason instead of matching its own prompt text. Tool calls drop from 7180/3560/3566 ms to 355/88/91 ms (spawn+init+echo, echo, pwd; darwin, production defaults). The loader composition suite now pins the fast path by pushing idleSilenceMs beyond the send bound, and a real-PTY case proves PS1 self-healing. Fixes #2585
shell/ — bash capability family
English | 中文
The capability family spans the canonical executor seam, its implementations, the shared shell environment, and the model-facing tools. All are product packages.
| Package | Role | ctx key |
|---|---|---|
shell/ |
Defines the executor contract shared by Service Providers and Consumers. | ctx.shell |
bash-local/ |
Executes commands through the local subprocess service. |
(registers ctx.shell) |
bash-sandbox/ |
Applies the configured sandbox backend before local execution. |
(registers ctx.shell) |
pwsh-local/ |
Executes PowerShell commands with Windows-specific process behavior. | (registers ctx.shell) |
shell-env/ |
Provides the managed DSH_* environment shared by shell tools. |
ctx.shellEnv |
tool-bash/ |
Exposes Bash execution and background-job integration to the model. | (registers on ctx.tools) |
tool-pwsh/ |
Exposes PowerShell execution to the model. | (registers on ctx.tools) |
A leaf cordis.yml selects one executor implementation and the model-facing tools it needs. A sandboxed composition also selects a ctx.sandbox provider; the ACP example shows one complete wiring.
The subsystem reference — request/spec vocabulary, results, background processes, the service, and events — is docs/subsystems/shell.md.
