Unified skill for constraint generation, pre-action checking, circuit breaker management, and constraint lifecycle. Consolidates 7 granular skills into a single enforcement system.
Trigger: 行動前∨閾値到達 (pre-action or threshold reached)
Source skills: constraint-generator, circuit-breaker, emergency-override, constraint-lifecycle, constraint-versioning, positive-framer (partial), contextual-injection (partial)
openclaw install leegitw/constraint-engine
Dependencies: leegitw/failure-memory (for eligibility data)
# Install with dependencies
openclaw install leegitw/context-verifier
openclaw install leegitw/failure-memory
openclaw install leegitw/constraint-engine
Standalone usage: Requires failure-memory for constraint generation from observations. For full lifecycle management, install the complete suite (see Neon Agentic Suite).
Data handling: This skill operates within your agent's trust boundary. When triggered,
it uses your agent's configured model for constraint checking and generation. No external APIs
or third-party services are called. Results are written to output/constraints/ in your workspace.
Instructions get ignored. Rules get forgotten. Documentation goes unread. This skill takes a different approach — constraints generated from actual failures:
R≥3 ∧ C≥2)The insight: A constraint born from "this actually broke" carries more weight than "this might break." Consequences teach better than instructions.

Configuration is loaded from (in order of precedence):
.openclaw/constraint-engine.yaml (OpenClaw standard).claude/constraint-engine.yaml (Claude Code compatibility)# .openclaw/constraint-engine.yaml
thresholds:
R: 3 # Recurrence threshold (default: 3)
C: 2 # Confirmation threshold (default: 2)
false_positive_max: 0.2 # Max D/(C+D) ratio (default: 0.2)
circuit_breaker:
critical_threshold: 3 # Violations to trip for CRITICAL
important_threshold: 5 # Violations to trip for IMPORTANT
minor_threshold: 10 # Violations to trip for MINOR
window_days: 30 # Violation window (default: 30 days)
lifecycle:
review_reminder_days: 80 # Days before 90-day review to remind
Observation becomes eligible for constraint when:
R≥3 ∧ C≥2 ∧ D/(C+D)<0.2 ∧ sources≥2
| Criterion | Meaning |
|---|---|
| R≥3 | At least 3 recurrences |
| C≥2 | At least 2 human confirmations |
| D/(C+D)<0.2 | False positive rate under 20% |
| sources≥2 | Observed by at least 2 different sources |
Constraints are automatically reframed positively:
| Negative | Positive |
|---|---|
| "Don't commit without tests" | "Always run tests before commit" |
| "Don't push to main directly" | "Always create PR for main changes" |
| "Don't deploy without review" | "Always get code review before deployment" |
| "Don't skip migrations" | "Always run database migrations before release" |
[CHECK BLOCKED] deploy production
Constraint violated: CON-20260212-005
"Always get code review approval before production deployment"
Severity: CRITICAL
Action: Request review via /ro twin, then retry deployment.

✓ CON-20260210-001: Tests pass

What this skill does NOT do:
Dependency note:
This skill reads observation data from failure-memory skill's workspace (.learnings/).
Install leegitw/failure-memory for full constraint generation functionality.
Without failure-memory, constraint generation will have no observation data to process.
Audit logging:
Override actions are logged to output/hooks/blocked.log for audit purposes.
Logs are stored locally in the workspace only.
