Goal Convergence

Goal-oriented autonomous loop with external completion oracle. Based on Addy Osmani's Loop Engineering principle: "Keep going until a verifiable stopping condition holds, with a separate small model checking completion."

When to Activate

User invokes /goal command
Heartbeat auto-creates a goal from scan failures
Triage item is promoted to a goal via /triage act <id> goal
Session resumes with an active goal state file

Core Concept: Maker-Oracle Separation

The model that wrote the code is too nice grading its own homework. A second model (the oracle) with different instructions and READ-ONLY tools catches what the first talked itself into.

Maker (primary model, full tools)
  │
  ▼ produces iteration output
  │
Oracle (different model, read-only)
  │
  ├─ ALL conditions pass → CONVERGE (goal done)
  ├─ Some fail + budget remains → nextHint → LOOP (maker iterates)
  └─ Budget exhausted → ESCALATE (triage inbox)

Goal Lifecycle

CREATE → ACTIVE → [iterate] → CONVERGED
                       │
                       ├──── PAUSED (manual /goal pause)
                       └──── ESCALATED (budget exhausted or repeated failure)

States:

active: Maker-oracle loop is running
paused: Manually paused, resumes with /goal resume
converged: All stopping conditions met, goal complete
escalated: Cannot converge within budget, needs human triage
failed: Explicitly abandoned

Stopping Conditions

Each goal has one or more stopping conditions. ALL must pass for convergence.

Type	Command Pattern	Example
`test_pass`	Test runner exits 0	`npm test`
`lint_clean`	Linter exits 0	`npm run lint -- --quiet`
`coverage_threshold`	Coverage >= N%	`npm test -- --coverage`
`build_pass`	Build succeeds	`npm run build`
`custom_command`	Any command exits 0	`grep -r "TODO" src/ \| wc -l`

Oracle Protocol

The oracle receives:

The goal objective (natural language)
All stopping condition commands and their latest output
The maker's iteration summary
Previous iteration history (last 3)

The oracle returns:

{
  "converged": false,
  "conditionResults": [
    {"type": "test_pass", "passed": false, "output": "2 tests failing"},
    {"type": "lint_clean", "passed": true, "output": ""}
  ],
  "reasons": ["2 tests still failing in auth module"],
  "nextHint": "Focus on src/auth/refresh.test.ts — the token expiry mock is stale",
  "confidence": 0.85
}

Budget Management

Three budget dimensions, any exhaustion triggers escalation:

Dimension	Default	Rationale
Iterations	15	Prevents infinite loops
Wall time	2h	Bounds real-world duration
Cost (USD)	$10	Prevents runaway API spend

On escalation, the goal:

Persists full state to ~/.claude/goals/{goalId}.json
Creates a triage inbox item with context
Marks state as escalated
Reports final status to user

Inter-Session Persistence

Goals survive session restarts:

SessionEnd hook serializes active goals
SessionStart hook detects active goals and notifies user
/goal resume re-enters the loop with oracle's last nextHint

State file: ~/.claude/goals/{goalId}.json (follows schemas/goal.schema.json)

Integration Points

/heartbeat: Auto-creates goals from scan failures
/triage: Escalated goals land in triage; triage items can become goals
/checkpoint: Each iteration implicitly checkpoints
/verify: Oracle internally uses verification patterns
wave-execution: Multiple goals can run in parallel waves
rework-loop: Failed iterations trigger blame-attributed rework

Hard Bans

Oracle MUST be a different model than maker (eliminates self-grading bias)
Oracle MUST NOT have write tools (prevents it from "helping" fix issues)
Goals MUST have at least one stopping condition (no open-ended loops)
Budget MUST have at least one limit set (no unbounded execution)
State MUST persist to disk (no goals lost on crash)

Example

User: /goal "make all tests pass"

System infers:
  objective: "make all tests pass"
  stoppingConditions: [{type: "test_pass", command: "npm test"}]
  budget: {maxIterations: 15, maxDuration: "2h", maxDollars: 10}
  oracle: {model: "haiku"}

Iteration 1:
  Maker: reads test output, fixes obvious import error in auth.ts
  Oracle: runs `npm test` → 1 test still failing → {converged: false, nextHint: "..."}

Iteration 2:
  Maker: fixes token refresh logic based on oracle hint
  Oracle: runs `npm test` → all pass → {converged: true}

Result: CONVERGED in 2 iterations, $0.45 spent
