v0.4.0 — Staged process and AgenticLoop

What's new in v0.4.0

All features are backward compatible — no breaking changes.

Staged process

Third orchestration mode: stages run in sequence, while tasks within a single stage run concurrently. The output of each stage feeds the following ones via Task.Context. Stages marked Optional continue on failure.

crew.Process = crewai.Staged
crew.Stages = []crewai.Stage{
    {Name: "collect", Tasks: []*crewai.Task{researchA, researchB}},
    {Name: "synthesize", Tasks: []*crewai.Task{write}},
}

Agentic loop

Optional Plan → Execute → Evaluate → Refine cycle. Opt-in via Agent.Loop or Task.Loop. Supports independent evaluator, pass threshold, skip-plan, and rewrite-only refine.

agent.Loop = crewai.NewAgenticLoop(
    crewai.WithMaxRefinements(3),
    crewai.WithPassThreshold(80),
)

New sentinels

• ErrNoStages
• ErrEvaluationFailed
• ErrInvalidEvaluation

Examples

• go run ./examples/staged
• go run ./examples/agentic_loop (offline, mock LLM)
