Metadata

  • Commit message: feat(invariants): implement invariant add/list/remove CLI, enforcement during strategize, and persistence
  • Branch name: feat/v3.2.0-invariant-management-system

Background and Context

As part of the v3.2.0 milestone (M3: Decisions + Validations + Invariants), the agent system needs a mechanism for users to define constraints — called invariants — that must hold true across all planning sessions. Without invariants, the Strategize phase has no way to enforce user-defined rules or constraints, leading to plans that may violate known business or technical requirements.

This Epic delivers the full Invariant Management System: CLI commands to create, list, and remove invariants; persistence of invariants to the database; and automatic enforcement of invariants during the Strategize phase.

This Epic blocks the parent Legendary issue #8475.

Expected Behavior

  • Users can create invariants via agents invariant add "<constraint description>", which persists the invariant to the database
  • Users can view all active invariants via agents invariant list, which displays them in a readable format
  • Users can remove a specific invariant via agents invariant remove <invariant-id>
  • During the Strategize phase, all active invariants are loaded and enforced — any plan that would violate an invariant is rejected or flagged before execution
  • Invariants survive restarts (persisted to the database)

Acceptance Criteria

  • agents invariant add "<description>" creates a new invariant and persists it to the database
  • agents invariant list displays all active invariants with their IDs and descriptions
  • agents invariant remove <id> deletes the specified invariant from the database
  • Invariants are loaded and enforced during the Strategize phase
  • A plan that violates an active invariant is rejected with a clear error message identifying the violated invariant
  • Invariant data is persisted to the database (durable across restarts)
  • Database schema migrations for invariants are included and reversible
  • Test coverage >= 97% for all new code in this Epic

Subtasks

  • Design and implement the Invariant data model and database schema
  • Write and apply database migration for the invariants table
  • Implement agents invariant add CLI command
  • Implement agents invariant list CLI command
  • Implement agents invariant remove CLI command
  • Implement invariant loading and enforcement hook in the Strategize phase
  • Implement clear error messaging when an invariant is violated
  • Write unit tests for invariant CRUD operations (>= 97% coverage)
  • Write integration tests for invariant enforcement during Strategize
  • Update documentation / help text for new CLI commands
