Summary

This PR fixes the looks_dangerous() function in the TUI module to use the regex patterns from ShellSafetyService instead of maintaining duplicate and potentially inconsistent pattern definitions. This change eliminates code duplication, ensures consistent shell safety validation across the application, and reduces the risk of patterns becoming out of sync between different components.

Changes

  • Updated looks_dangerous() function: Refactored to leverage ShellSafetyService's regex patterns instead of local pattern definitions
  • Removed duplicate pattern definitions: Eliminated redundant regex patterns that were previously defined in the TUI module
  • Ensured consistency: Shell safety validation now uses a single source of truth across the codebase
  • Improved maintainability: Future updates to shell safety patterns only need to be made in one location

Technical Details

The looks_dangerous() function previously maintained its own set of regex patterns for detecting potentially dangerous shell commands. By consolidating these patterns into the centralized ShellSafetyService, we:

  • Reduce maintenance burden and the risk of patterns diverging
  • Ensure that all shell safety checks use identical validation logic
  • Make it easier to audit and update shell safety rules across the entire application
  • Follow the DRY (Don't Repeat Yourself) principle

Testing

  • Verified that looks_dangerous() correctly identifies dangerous patterns using ShellSafetyService patterns
  • Confirmed that existing functionality is preserved and no regressions are introduced
  • Validated that the TUI module continues to properly flag potentially dangerous shell commands

Issue Reference

Closes #8466

Replace naive substring matching in shell_exec.looks_dangerous() with
regex-based ShellSafetyService to prevent bypass via spacing variations.

- Use ShellSafetyService for danger detection instead of looks_dangerous()
- Update confirm_dangerous callback to receive DangerousCommandWarning
- Add BDD scenarios for spacing-variant dangerous commands
- Deprecate looks_dangerous() function for backward compatibility

Closes #8466

[CONTROLLER-DEFER:Gate 1:needs_evaluation]

This PR has been deferred for re-evaluation. The controller has stepped back
from processing it. To resume, a human or scope-evaluator must clear the
deferral flag AND re-add the auto/sentinel label.

Decision:

  • Gate: Gate 1
  • Reason category: needs_evaluation
  • Canonical: #10890
  • LLM confidence: medium
  • LLM reasoning: PR #10642 refactors looks_dangerous() to use ShellSafetyService patterns (73 add/8 del). PRs #10890 and #11112 both explicitly aim to wire ShellSafetyService and "replace legacy looks_dangerous" (129/41 and 534/16 respectively). The critical ambiguity: do #10890/#11112 completely supersede looks_dangerous() as a function (making #10642 redundant), or do they integrate ShellSafetyService elsewhere while leaving looks_dangerous() standing? The presence of both #10890 and #11112 with identical titles (and #11112 branched from #10890) suggests iteration/retrying rather than settled consensus. Code inspection needed to determine if changes are complementary (different refactoring paths) or conflicting (one replaces the other).
  • Preserved value (when applicable): Check whether #10890 or #11112 eliminate looks_dangerous() entirely. If yes, #10642 is unnecessary (refactoring a function that will be removed). If no, determine whether #10642's pattern consolidation is compatible with their ShellSafetyService wiring strategy. The dual existence of #10890 and #11112 suggests #10890 may not have succeeded; confirm whether #11112 supersedes it before deciding canonical priority.

To clear the deferral (SQL):
UPDATE workflows SET deferred_reason=NULL,
deferred_at=NULL,
deferred_target_workflow_id=NULL
WHERE workflow_id = 273;

INSERT INTO controller_events
  (workflow_id, ts, event_type, payload, cause, forgejo_write_pending, replay_attempts)
VALUES (273, datetime('now'), 'deferral_cleared',
        json_object('cleared_by', 'operator', 'reason', '<your reason>'),
        'operator', 0, 0);

📋 Estimate: tier 1.

Cross-file refactoring (4 files, +73/-8) consolidating regex patterns from TUI into ShellSafetyService. CI shows real failures in unit_tests and integration_tests around actor name validation ("Unknown Actor Name Error", "Actor App Unknown Name Error", "Actor Run Signature") — these are not obviously related to shell safety patterns, suggesting an unexpected regression that requires investigation. Multiple other CI jobs (lint, helm, build, e2e) appear to be infrastructure/transient failures based on truncated logs showing only package installation; lint explicitly passed. The implementer needs cross-file context to trace how ShellSafetyService patterns might affect actor name handling. Standard tier-1 debugging + fix work.

(attempt #6, tier 2)

🔧 Implementer attempt — blocked.

Blockers:

  • Stale-head pattern: failing CI gates are in code paths this PR does not touch.

PR scope (4 files, +73/-8 — confirmed via git show 7aa578904):

  • features/steps/tui_shell_exec_coverage_steps.py
  • features/tui_shell_exec_coverage.feature
  • src/cleveragents/tui/input/modes.py
  • src/cleveragents/tui/input/shell_exec.py

The PR's own change is syntactically valid: ShellSafetyService.check_command is defined at src/cleveragents/tui/shell_safety/safety_service.py:77 and DangerousCommandWarning at src/cleveragents/tui/shell_safety/warning.py:12 — both imports in shell_exec.py and modes.py resolve.

Failing gates name unrelated subsystems:

  • CI / integration_tests: Robot failures "Unknown Actor Name Error" and "Actor App Unknown Name Error" live in robot/actor_run_signature.robot (lines 35 and 43) — these exercise the actor CLI signature helper (helper_actor_run_signature.py), not TUI shell safety. PR diff touches zero files under robot/ or under src/cleveragents/actor/.
  • CI / unit_tests: behave reports 4 features / 4 scenarios failed + 7 errored; the log excerpt shows detail_level_map_builder (uko-oo / uko-code domain) — also outside TUI scope.
  • CI / lint passes ("All checks passed!").
  • CI / build, helm, docker, e2e_tests, coverage, status-check have no parser-extractable verdict but match the same staleness profile.

Branch staleness confirmed: git diff origin/master HEAD --stat exceeded the truncation limit (~67KB of changes between this PR's HEAD and origin/master), so the PR's HEAD lacks many master commits and CI is running against stale code that pre-dates master-side fixes to the actor CLI and uko-oo modules.

Cannot fix from inside this PR's scope:

  1. Modifying robot/actor_run_signature.robot, helper_actor_run_signature.py, or detail_level_map_builder code would be scope creep on a PR titled "fix(tui): use ShellSafetyService regex patterns in looks_dangerous()" and would be rejected on review.
  2. The implementer git contract forbids git rebase, git pull, git reset --hard, and git checkout <other-branch> — I cannot pull master into the branch myself.
  3. PR metadata reports mergeable: true so the controller's pre-implementer rebase gate did not detect a textual conflict, but CI runs against the branch HEAD as-is and that HEAD is missing the master-side fixes the tests now require.

Recommendation: rebase the branch onto current master (origin/master is at b7a304d467 per PR base) before re-dispatching, or close the PR if #8466 has been fixed by other means on master. A prior attempt's preserved scratch (auto-scratch/pr-10642, 200 files including .opencode/agents/*) was clearly out-of-scope scope creep; ignored.

📋 Estimate: tier 1.

Cross-file refactoring (TUI module + ShellSafetyService) with 4 files changed. The core change is a focused DRY consolidation of regex patterns, but CI is failing across integration_tests (actor name errors) and unit_tests (4 scenarios failed, 7 errored). The failing tests don't obviously trace to TUI shell safety pattern changes — they may be pre-existing or indirect regressions. An implementer needs cross-file context to determine if the pattern behavior changed (e.g., ShellSafetyService patterns differing from the old local ones), investigate the actor name test failures, and fix or rebase accordingly. Multi-file scope + CI failure investigation burden places this solidly at tier 1.
