Summary

The AutomationGuard sub-model is fully defined and unit-tested in isolation, but its constraints are never called by ToolRuntime._enforce_capabilities(). The guard evaluation method AutomationProfile.check_guard() is only invoked from AutomationProfileService.evaluate_guard() (a test/CLI utility), and never from the actual tool execution pipeline. This means all six AutomationGuard constraints are silently bypassed during real plan execution.

What Was Tested

Code-level analysis of:

src/cleveragents/domain/models/core/automation_profile.py — check_guard() method
src/cleveragents/tool/lifecycle.py — ToolRuntime._enforce_capabilities() method
src/cleveragents/application/services/automation_profile_service.py — evaluate_guard() method

Expected Behavior (from spec §"Automation Guard Sub-Model")

Guard evaluation is performed via AutomationProfile.check_guard(tool_name, is_write, cost_so_far, calls_so_far, scope). Evaluation order: denylist → allowlist → tool call limit → budget cap → write approval → apply approval.

The six guard constraints that should be enforced at tool invocation time:

tool_denylist — tools on the denylist always require human approval
tool_allowlist — only allowlisted tools may be called automatically
max_tool_calls_per_step — maximum tool invocations per step
max_total_cost (AutomationGuard) — per-invocation budget cap
require_approval_for_writes — require approval for write operations
require_approval_for_apply — require approval before apply phase

Actual Behavior

ToolRuntime._enforce_capabilities() enforces only SafetyProfile constraints (unsafe tool gating, skill categories, sandbox, human approval, cost limits, retry limits). It never calls check_guard() or reads the AutomationProfile.guards field.

# src/cleveragents/tool/lifecycle.py — _enforce_capabilities()
# Only SafetyProfile constraints are checked. AutomationGuard is never consulted.
if ctx.safety_profile is not None and cap.unsafe and not ctx.safety_profile.allow_unsafe_tools:
    raise ToolSafetyViolationError(...)
# ... (more SafetyProfile checks)
# AutomationGuard.tool_denylist? Never checked.
# AutomationGuard.tool_allowlist? Never checked.
# AutomationGuard.max_tool_calls_per_step? Never checked.
# AutomationGuard.max_total_cost? Never checked.
# AutomationGuard.require_approval_for_writes? Never checked.

Grep confirms check_guard is only defined and called in test/CLI code:

src/cleveragents/application/services/automation_profile_service.py:282:  return profile.check_guard(...)
src/cleveragents/domain/models/core/automation_profile.py:277:  def check_guard(...)

No call to check_guard() exists in ToolRuntime, PlanApplyService, or any plan execution path.

Impact

A plan with tool_denylist: ["rm", "drop_table"] will NOT block those tools
A plan with tool_allowlist: ["read_file"] will NOT restrict other tools
A plan with max_tool_calls_per_step: 5 will NOT stop at 5 calls
A plan with require_approval_for_writes: true will NOT pause for write approval
All AutomationGuard configuration is effectively dead code at runtime

Steps to Reproduce

Create a custom automation profile with guards.tool_denylist: ["some_tool"]
Execute a plan using that profile
Observe that some_tool is invoked without any guard check

Code Location

Guard definition: src/cleveragents/domain/models/core/automation_guard.py
Guard evaluation: src/cleveragents/domain/models/core/automation_profile.py:277 (check_guard)
Missing integration: src/cleveragents/tool/lifecycle.py:_enforce_capabilities()

Fix Required

ToolRuntime._enforce_capabilities() must be updated to:

Accept the resolved AutomationProfile (or AutomationGuard) as a parameter
Call profile.check_guard(tool_name, is_write, cost_so_far, calls_so_far, scope) before executing each tool
Raise an appropriate error or pause for approval when GuardResult.allowed == False

## Summary The `AutomationGuard` sub-model is fully defined and unit-tested in isolation, but its constraints are **never called by `ToolRuntime._enforce_capabilities()`**. The guard evaluation method `AutomationProfile.check_guard()` is only invoked from `AutomationProfileService.evaluate_guard()` (a test/CLI utility), and never from the actual tool execution pipeline. This means all six `AutomationGuard` constraints are silently bypassed during real plan execution. ## What Was Tested Code-level analysis of: - `src/cleveragents/domain/models/core/automation_profile.py` — `check_guard()` method - `src/cleveragents/tool/lifecycle.py` — `ToolRuntime._enforce_capabilities()` method - `src/cleveragents/application/services/automation_profile_service.py` — `evaluate_guard()` method ## Expected Behavior (from spec §"Automation Guard Sub-Model") > Guard evaluation is performed via `AutomationProfile.check_guard(tool_name, is_write, cost_so_far, calls_so_far, scope)`. Evaluation order: denylist → allowlist → tool call limit → budget cap → write approval → apply approval.

Architectural Confirmation

The spec is correct. The AutomationGuard constraints must be enforced at tool invocation time via check_guard().

Spec reference: §"Automation Guard Sub-Model" — guard evaluation is performed via AutomationProfile.check_guard(tool_name, is_write, cost_so_far, calls_so_far, scope) with evaluation order: denylist → allowlist → tool call limit → budget cap → write approval → apply approval.

Implementation fix required (tracked in this issue):

ToolRuntime._enforce_capabilities() must accept the resolved AutomationProfile (or AutomationGuard)
Call profile.check_guard(...) before executing each tool
Handle GuardResult.allowed == False appropriately (raise error or pause for approval)

No spec change needed — the spec is correct and complete.
