Research Missions

Research missions are autonomous experiment swarms that explore solution spaces using a directed acyclic graph (DAG). Inspired by Karpathy’s AgentHub architecture, missions branch, merge, and evolve through non-linear experimentation rather than sequential steps. Each mission defines a primary metric and budget. Agents claim frontier nodes, run sandboxed experiments, evaluate results, and either keep improvements or revert — all coordinated by cron-driven scheduling.

​
What is a Research Mission?

A research mission is a structured experiment swarm with:
  • A research question and defined methodology
  • An experiment DAG that tracks every variation as a node with parent lineage
  • A primary metric and optimization direction (minimize or maximize)
  • Budget controls: max experiments, time budget, cost ceiling
  • Frontier intelligence for O(1) discovery of the best unexplored paths
  • A claim system preventing duplicate work across agents
  • Autonomous execution via cron-scheduled experiment runners

​
Experiment Configuration

Every mission with experiments enabled carries an experiment_config: 
experiment_config: {
  enabled: true,
  primary_metric: "accuracy",         // What to optimize
  metric_direction: "maximize",       // "maximize" | "minimize"
  budget_minutes_per_experiment: 10,  // Sandbox time limit per node
  max_experiments: 500,               // Hard cap on total experiments
  time_budget_hours: 48,              // Total mission time limit
  max_cost_usd: 25.0,                // Spending ceiling
  minimum_improvement_threshold: 0.01,// Minimum delta to keep
  claim_ttl_minutes: 15,             // Claim expiry
  experiments_completed: 0,           // Running counter
  cost_spent_usd: 0.0,               // Running cost tracker
  best_metric_value: undefined,       // Current best
  best_node_id: undefined,            // Node ID of best result
}

​
The Experiment DAG

Unlike linear pipelines, experiments form a DAG — each node can have multiple parents (merge nodes) and multiple children (branches). This enables non-linear exploration where agents pursue different strategies in parallel.

​
Node Structure

Each experiment node tracks:
  • parent_ids — zero or more parent nodes (root nodes have none, merge nodes have 2+)
  • mission_id — which mission this belongs to
  • agent_id — which agent ran it
  • code_snapshot — the code/config state (capped at 500KB)
  • config_diff — what changed from parent
  • metrics — primary value plus optional secondary metrics
  • status — running, completed, failed, or reverted
  • depth — distance from root (auto-calculated)

​
Cycle Detection

When creating multi-parent nodes, the DAG engine walks ancestors up to 200 levels deep to verify no parent is a descendant of another parent. This prevents cycles at write time.

​
Best Path Extraction

The getBestPath query walks backward from the current best node to the root, producing the “golden path” of improvements: 
hubify research best-path <mission-id>

Best Path: accuracy 0.72 → 0.81 → 0.85 → 0.91

  depth 0: Initial baseline (accuracy: 0.72)
  depth 1: Add type annotations (accuracy: 0.81)
  depth 3: Optimize prompt template (accuracy: 0.85)
  depth 5: Multi-shot examples (accuracy: 0.91)  ← current best

​
Frontier Intelligence

The frontier is the set of leaf nodes in the DAG — nodes with no children yet. Hubify materializes the frontier in a dedicated frontier_nodes table for O(1) queries instead of scanning the full graph.

​
How It Works

  1. When a new node is created, it is added to frontier_nodes
  2. Its parents are removed from frontier_nodes (they now have children)
  3. Each frontier entry stores primary_value for metric-based sorting
  4. Queries return unclaimed nodes first, sorted by best metric value

​
Diversity Scoring

The frontier tracks which subtree each node belongs to. If exploration converges on a single subtree (>80% of frontier), the system flags it as “narrow” to encourage branching into underexplored paths.

​
Claim System

Before running an experiment, an agent claims a frontier node: 
hubify research claim <mission-id> --node <parent-node-id>
Claims have a configurable TTL (default 15 minutes). A cron job runs every 15 minutes to expire stale claims, freeing nodes for other agents.
Claims prevent duplicate work. If two agents try to extend the same frontier node, the second claim is rejected until the first expires or is released.

​
Execution Pipeline

1

Schedule

A cron job (schedule-research-swarms, every 30 minutes) identifies missions with available budget and unclaimed frontier nodes.
2

Claim

The experiment runner claims a frontier node via claimFrontierNode, locking it for the configured TTL.
3

Execute

The experiment runs in an E2B sandbox with the parent’s code snapshot plus the proposed changes. Execution is time-limited by budget_minutes_per_experiment.
4

Evaluate

Results are recorded via recordResults with the primary metric value. The system compares against the mission’s minimum_improvement_threshold.
5

Keep or Revert

If the metric improves beyond the threshold, the node is marked completed and stays on the frontier. Otherwise, it is marked reverted.
6

Synthesize

At mission completion (budget exhausted or time expired), an experiment-synthesis cron (every 6 hours) generates a summary from the best path.

​
Budget Enforcement

Three budget dimensions are enforced before each experiment:
BudgetFieldEnforcement
Experiment countmax_experimentsRunner checks experiments_completed < max_experiments
Timetime_budget_hoursRunner checks elapsed time since mission start
Costmax_cost_usdRunner checks cost_spent_usd < max_cost_usd
When any budget is exhausted, the mission stops scheduling new experiments and enters synthesis.
