Thanks for the updates! I spotted a security regression in the new ShellSafetyService wiring that we should address before merging (see inline for details).
The new ShellSafetyService hook never actually blocks commands that it deems unsafe. We only pass
confirm_dangerousdown torun_shell_command, but that helper still runs its legacylooks_dangerous()check before it ever calls the confirmation callback. Becauselooks_dangerous()only knows about a tiny handful of patterns (rm -rf /, git push --force, mkfs, dd, fork bombs), anything else that ShellSafetyService flags — e.g.curl https://example.com/install.sh | bash,chmod -R 777 ., etc. — skips the confirm path entirely. Even if ShellSafetyService returnsallowed=False(or the user setCLEVERAGENTS_ALLOW_DANGEROUS_SHELL=0), the command still executes.Can we thread the safety verdict all the way through so
run_shell_commandhonours it for every command? That could be as simple as invoking the confirm callback unconditionally, or plumbing a separate flag that short-circuits execution whenallowedis false. Without that change the new ShellSafetyService integration is purely cosmetic and leaves us with a regression in dangerous command handling.Code Review — PR #6576
Reviewed PR with focus on ShellSafetyService integration within TUI and safety checks triggering appropriately without UX regression.

1. Dead state:
_last_shell_warningand_shell_warning_activeare never read —src/cleveragents/tui/app.pyBoth fields are set in
_show_shell_warningand_clear_shell_warningbut are never consumed anywhere in the codebase:These fields add cognitive overhead and mislead future maintainers into thinking they serve a purpose. A reader will search for consumers of
_last_shell_warningand_shell_warning_activeand find none, creating confusion about the intended design.Fix: Either remove both fields entirely, or add a concrete consumer (e.g., expose
_shell_warning_activeas a property for testing, or use_last_shell_warningin a tooltip/status display). If they are placeholders for future functionality, document that intent with a comment.2. DRY violation:
_submit_textduplicated across step filestui_app_coverage_steps.py(lines ~370–380) andtui_shell_safety_steps.py(lines ~17–24) both define an identical_submit_texthelper:This creates a maintenance burden: any change to the helper must be made in two places. If they diverge, tests will behave differently depending on which step file is loaded.
Fix: Extract
_submit_text(and_submit_text_with_mocked_shell) to a shared helper module (e.g.,features/steps/_tui_helpers.py) and import from both step files. Alternatively, import the helper fromtui_app_coverage_stepsintotui_shell_safety_steps.3.
tui_app_coverage_steps.pystill exceeds the 500-line limit (~565 lines)This was flagged in reviews 4593, 4704, and 4889. The split into
tui_shell_safety_steps.pyreduced the file but it remains ~565 lines — above the CONTRIBUTING.md limit of 500 lines. The mock infrastructure (_build_mock_textual,_install_mock_textual,_restore_modules) accounts for ~100 lines and could be extracted to a sharedconftest.pyor_tui_mock_helpers.pymodule, bringing both files within the limit.🟡 Non-Blocking Observations
4. Module docstring regression in
tui_app_coverage_steps.pyThe original docstring listed all covered source lines (31–38, 81–100, 102–112, etc.), which was valuable for maintainers to understand the test intent at a glance. The replacement is minimal:
Consider restoring the line-coverage annotations or updating them to reflect the current coverage targets. This documentation is especially useful when the source file changes and tests need to be updated.
5.
hasattrguards in_show_shell_warningand_clear_shell_warningsuggest unclear type contractSince
promptis typed asPromptInput(a known class), thesehasattrguards suggest uncertainty about whether the method exists. IfPromptInputalways hasadd_class/remove_class, remove the guards. If it may not (e.g., in test environments), document why and consider using a Protocol or ABC to make the contract explicit.6.
_handle_shell_warningcontains a guard that can never be True at runtime_handle_shell_warningis only reachable as thewarn_callbackof_shell_safety, which is only instantiated whenself._shell_warn_enabledisTrue. So the guardif not self._shell_warn_enabledcan never be True at runtime. Either remove it or add a comment explaining it is a defensive measure for subclass overrides.7.
InputModeRouterre-instantiated on everyon_input_submittedcallThe router is created fresh on each submission with the same
shell_confirmandshell_safetyconfiguration. Consider caching it as an instance attribute (initialised in__init__) to make the dependency injection more explicit and avoid repeated object creation.8.

The field exists but is ignored, which creates a confusing API.

🌱 Grooming: proceed — PR cleared for processing.
(check
no_duplicates, categoryno_duplicates)Anchor PR #6576 has clear topical overlap with #10890 and #11112 (all address ShellSafetyService TUI integration). However, the anchor is distinctly broader in scope: 11 files modified vs. 3–5 for others, explicit issue closure (#6361), and includes foundational test infrastructure (Behave + Robot). The other PRs focus narrowly on run_shell_command wiring—a subset of the anchor's broader router + confirmation/warning flow integration. The anchor is the canonical, more-complete solution.
event occurred 2026-05-31T14:43:00.320740+00:00
📋 Estimate: tier 1.
11 files, +368/-70 across TUI feature code, ShellSafetyService integration, Behave steps, and Robot Framework tests. Real integration test failures (2/2 Robot tests fail) require cross-file diagnosis and fixes — not infra noise. Multi-framework test burden (Behave + Robot) and service-integration scope firmly places this at tier 1.

(check
no_duplicates, categoryno_duplicates)Anchor PR #6576 addresses comprehensive ShellSafetyService integration across the TUI app with test coverage (Behave/Robot) and spec-aligned flows. Related PRs #10890 and #11112 both target a specific function (wire into run_shell_command) with narrower scope. The anchor is older (lower PR #), closes a specific issue (#6361), and touches more files (13 vs 4-6), suggesting it's the primary integration work while others are complementary. Although topical overlap exists in the ShellSafetyService space, scope differences and architectural scale indicate distinct work rather than duplication.
📋 Estimate: tier 1.
13 files, +400/-85 lines spanning TUI app core, ShellSafetyService integration, shell input router, confirmation/warning flows, split-out Behave steps, and new Robot Framework coverage. Multi-subsystem scope (TUI + safety service + test layers), new logic branches in the router and gating defaults, and substantial test rework all confirm tier 1. CI coverage gate is failing — PR author documents a test-environment issue (suite cleanup removes working-tree paths) but the implementer must resolve it regardless. Not tier 2 because no architectural redesign or cross-repo coordination is required.

(check
no_duplicates, categoryno_duplicates)PR #6576 addresses issue #6361 with a comprehensive ShellSafetyService integration covering shell input router enforcement, TUI confirmation/warning flows, and test coverage. Related open PRs (#10642, #10890, #11112) target narrower sub-components (regex patterns, run_shell_command wiring) with distinct titles and smaller diffs. No evidence these are duplicates; they appear to be complementary work on different architectural layers rather than competing solutions to the same problem.
📋 Estimate: tier 1.
13 files changed (+399/-84). Integrates ShellSafetyService verdicts into the TUI shell input router (logic change), aligns confirmation/warning UI flows with spec, splits Behave step files, and adds Robot Framework coverage. Multi-file scope spanning router logic, UI behavior, and test infrastructure. New test branches added across two test frameworks. Not mechanical — requires cross-file context to review safely. CI passing. Clearly tier 1.

(check
no_duplicates, categoryno_duplicates)All three ShellSafetyService PRs (#6576, #10890, #11112) share topical overlap but appear to address different integration scopes. #6576 focuses on input router enforcement, default gating, and test infrastructure improvements (Behave + Robot); #10890/#11112 narrow to run_shell_command refactoring. #6576 is more comprehensive (13 files, 463 add), includes explicit testing work not mentioned in competitors, and comes from issue #6361. These appear complementary rather than duplicative.
📋 Estimate: tier 1.
13 files changed (+463/-84) spanning TUI app, ShellSafetyService integration, shell input router, Behave step definitions, and Robot Framework coverage. New logic branches added (safety verdict enforcement, default gating, confirmation/warning flow alignment). Test infrastructure restructured (Behave steps split, Robot coverage added, exec expectation tweaks). Cross-file context required to understand safety service interface, router wiring, and spec alignment. Clearly non-trivial multi-file work with new logic and test additions — solid tier 1. CI fully green (13/13 passed); documented test failures are suite-cleanup infrastructure artifacts, not code defects.
