Move the 18 flat packages/<name> packages into role-grouped dirs: core/, llm/, bash/, session-persistence/, ui/, support/. Group dirs are pure containers; each package keeps its @deepseek-ai/dsh-* name. Collapse the per-package tsconfig paths maps (base + typecheck) into one @deepseek-ai/dsh-* wildcard with a candidate per group, and derive the publint list from the hierarchy. Update all depth-coupled globs/configs (workspace, tsdown, vitest, eslint, knip, tsconfig includes/refs, per-package tsconfigs, generators, doc-script scopes, type-equiv manifest) and the cross-package/script relative imports in tests. Fix doc-typecheck's workspacePaths() to parse tsconfig JSONC via the TypeScript API instead of a regex comment-strip, which corrupted the new wildcard `/*/` path candidates. WIP: doc cross-links and package/RFC docs still to update.

# @deepseek-ai/dsh-bash-local
|
|
|
|
Local-subprocess implementation of the `@deepseek-ai/dsh-bash` executor seam: `LocalBashExecutor` spawns `bash -c <command>` per call in its own process group, collects bounded output with full-stream spill files, and escalates kills SIGTERM→SIGKILL across the whole group.
|
|
|
|
## Config
|
|
|
|
```yaml
|
|
- id: bash
|
|
name: '@deepseek-ai/dsh-bash-local'
|
|
config:
|
|
cwd: /path/to/workspace # default: process.cwd()
|
|
timeoutMs: 120000 # default foreground timeout
|
|
maxTimeoutMs: 600000 # cap for per-call overrides
|
|
maxOutputBytes: 64000 # per-stream in-memory cap; overflow spills to disk
|
|
```
|
|
|
|
## Behavior (and where it came from)
|
|
|
|
Design surveyed against the bash tools of Claude Code, OpenCode, Codex, and pi; the notable choices:
|
|
|
|
- **Spawn per call, no shell state** — every call is a fresh non-login `bash -c` (deterministic; no rc files). All four surveyed tools spawn per call. `XXX(stateful-shell)` in `src/run.ts` records the two proven stateful designs (Claude Code's cwd-only persistence; Codex's PTY exec sessions) for when real workflows demand them.
|
|
- **Process-group kills with escalation** — children are spawned `detached` (own process group); kills send SIGTERM to the group, then SIGKILL after a 3s grace (OpenCode's escalation; pipelines and subshells die with the parent). ESRCH is tolerated; daemons that re-parent away from the group can still survive — same caveat as the surveyed tools.
|
|
- **Tail-keep truncation + spill files** — output beyond `maxOutputBytes` keeps the in-memory TAIL (errors/results cluster at the end — pi/OpenCode rationale) while the FULL stream is appended to a temp file whose path is reported when available. If the final spill close reports a delayed writeback failure, the executor still returns the tail but withholds the path rather than advertising a possibly incomplete file.
|
|
- **Model-friendly env** — `NO_COLOR=1 TERM=dumb PAGER=cat GIT_PAGER=cat` (Codex's hardcoded set) so pagers and ANSI color don't garble results.
|
|
- **Background tasks** — `start()` returns immediately, no timeout applies (Claude Code detaches timeouts when backgrounding), `readOutput()` is incremental with whole-stream byte offsets, and disposal kills everything. The spec's opaque `owner` token is stored on the tracked task and returned by `ownerOf(id)` — the executor never interprets it (the consumer's access policy does), and because it lives with the task here it survives a `tool-bash` HMR reload.

## Sandboxing
|
|
|
|
`TODO(permissions/sandbox)`: execution policy does NOT belong in this package. Wrap the `tools/execute` waterfall (veto/ask) or implement a sandboxing `BashExecutor` — see docs/architecture.md § plugin checklist. Reference points: Claude Code wraps commands in sandbox-exec/bubblewrap; Codex applies seatbelt/landlock plus an execpolicy prefix-rule engine.
