Conversation
#3589) Make build_permission_target emit a distinct shell:external-path:<path> target when a shell command touches a path outside the workspace root, so a broad bash:*/"allow shell"/session grant cannot silently authorise out-of-workspace access. Reuses the existing command_parser and path_safety.resolve_within_root primitives (no new modules/params). Default-on and fail-closed, with a PRAISONAI_SHELL_WORKSPACE_BOUNDARY opt-out for trusted sandboxed/CI runs. Co-authored-by: MervinPraison <MervinPraison@users.noreply.github.com>

Greptile SummaryThe revision preserves shell command identity in approval targets so command-specific deny patterns continue to match external-path commands.
Confidence Score: 5/5The PR appears safe to merge. No blocking failure remains; the previously reported command-deny bypass is resolved by retaining the bash command target.

This PR adds deterministic unit tests. It does not add the required smoke test or real agentic test for this feature. Add a test where an Agent calls agent.start() with a real prompt, invokes the LLM, and prints the full output.

External targets bypass command denies
When a command covered by a command-specific deny rule such as bash:rm * references an out-of-workspace path, this replaces the command-bearing target with shell:external-path:<path>, so the deny pattern no longer matches and the prohibited operation can be authorized through the approval path.
How this was verified: The generated shell:external-path:/tmp/file target cannot match bash:rm * under the full-target fnmatch rule matching.

The previous approach replaced the bash:<command> approval target with a shell:external-path:<path> target for out-of-workspace commands. This both broke command-specific deny rules (a hard `deny: bash:rm *` no longer matched, regressing DENY -> ASK and letting a user approve a denied command) and collided with the existing `shell:` shell-prefix namespace in PermissionManager.check(). The out-of-workspace boundary is already fully implemented in PermissionManager (`_check_shell_command` + `_external_dir_target`): with a workspace_root configured, a broad `bash:*` allow escalates external paths to ASK while a command-specific deny still fires. build_permission_target now keeps the verbatim `bash:<command>` target so that machinery applies and command identity is preserved. - approval/utils.py: drop the redundant shell:external-path namespace and the _shell_external_paths helper; shell tools map back to bash:<command>. - tests: replace target-mangling assertions with boundary-enforcement tests that verify (a) broad bash:* does not cover external paths, (b) in-workspace stays allowed, (c) command-specific deny still fires on external paths, and (d) backward-compat with no workspace_root.

Fixes #3589
Summary
The built-in
execute_commandshell tool bypassed the workspace-containment boundary that file tools enforce: its approval scope/session grants flowed throughbuild_permission_targetas a flatbash:<command>, so a broadbash:*/ "allow shell" / session grant silently authorised commands touching paths anywhere on the host (~/.ssh,/etc, sibling repos).This makes
build_permission_target(approval/utils.py) emit a distinctshell:external-path:<path>target whenever a shell command touches a path that resolves outside the workspace root. Because the target lives in a different namespace frombash:, a broadbash:*/"allow shell"/session grant no longer covers it, and the offending path(s) are named so the grant is path-scoped β mirroring the file tools'edit:<path>/write:<path>targets.Why minimal / lightweight
PermissionManageralready has full shell workspace-boundary machinery (_check_shell_command+_external_dir_target+command_parser). The only gap was the scope/session-target layer used by the built-in shell tool.permissions.command_parser.parse_command(path extraction) andtools.path_safety.resolve_within_root(the same resolver file tools use). No new modules, no new Agent params, no new exports.[]so target derivation never breaks a call; the downstream boundary gate still applies). Explicit opt-out viaPRAISONAI_SHELL_WORKSPACE_BOUNDARY=0for trusted sandboxed/CI runs. Workspace root defaults to$PRAISONAI_WORKSPACE_ROOTor cwd.Behaviour
