Background and Context

Guard enforcement is the safety layer for autonomous execution. Without guards, autonomous plans could execute prohibited operations, exceed budget limits, or make unlimited tool calls. This is a safety-critical component that must be implemented before autonomous execution can be enabled in production.

Current Behavior

Guard enforcement is incomplete. Denylist checks are not enforced. Budget caps do not halt execution when exceeded. Tool call limits are not tracked per-plan.

Expected Behavior

Denylist guard blocks prohibited operations before execution. Budget cap guard halts execution when the budget is exceeded and surfaces a clear error. Tool call limit guard enforces per-plan tool call limits and rejects calls that would exceed the limit.

Acceptance Criteria

  • Denylist guard blocks operations matching denylist patterns
  • Budget cap guard halts execution when budget is exceeded
  • Tool call limit guard enforces per-plan tool call limits
  • Guard violations produce clear, actionable error messages
  • Guards are evaluated before each tool call
  • Guard configuration is loaded from automation profile
  • Test coverage >= 97% for all guard types

Metadata

  • Commit message: feat: implement guard enforcement denylist budget caps tool call limits
  • Branch name: feat/guard-enforcement-denylist-budget-tool-limits

Subtasks

  • Implement denylist guard with pattern matching
  • Implement budget cap guard with real-time tracking
  • Implement tool call limit guard with per-plan counters
  • Integrate guards into tool call execution pipeline
  • Implement guard configuration loading from automation profile
  • Write unit tests for each guard type
  • Write integration tests for guard enforcement in plan execution

Definition of Done

All three guard types (denylist, budget cap, tool call limit) are enforced during plan execution, violations produce clear errors, and test coverage >= 97%.

Verified — The v3.5.0 acceptance criterion explicitly requires: 'Guard enforcement works (denylist, budget caps, tool call limits).' This is a safety-critical requirement. Must Have for v3.5.0. Verified.
