crewai - 💡(How to fix) Fix Discussion: should crews be able to discover external task markets at runtime?

Not a feature request — genuine design question for the maintainers and community.

The gap I'm thinking about

CrewAI crews execute tasks defined at crew-creation time (or hardcoded in the task list). This works well when a human knows upfront what work the crew should do.

But here's a pattern we keep seeing in production: agents that need to discover new work autonomously, without a human re-configuring the crew between runs.

Example: a researcher crew that, when idle, should query an external task market for available research bounties, pick one, and execute it — without a human in the loop.

Design question

Should CrewAI support a TaskSource or TaskDiscovery abstraction? Something like:

class TaskSource(ABC):
    def poll(self) -> list[Task]: ...

crew = Crew(
    agents=[researcher, analyst],
    task_source=OABPTaskSource(server="https://example.com/api/missions")
)

Where the crew polls the source at the start of each run and builds its task list dynamically?

Why it matters for the 2026 agent ecosystem

The agent economy is moving toward agent-to-agent markets: one agent posts work, another discovers it and does it — no human in the loop. Open standards for this are starting to emerge (OABP, AIP-1). If CrewAI had a TaskSource hook, crews could integrate with these markets natively.

We've been running a live OABP server (github.com/Aigen-Protocol/aigen-protocol) and what we observe is that agents that can discover work autonomously have fundamentally different behavior than scripted agents. The bottleneck isn't task execution — it's task discovery.

My question to maintainers

1. Is a TaskSource / external task discovery abstraction something the team has considered?
2. Is there an existing hook or workaround in current CrewAI that handles this?
3. If not, would a minimal RFC PR be welcome, or is this out of scope for the framework?

Happy to discuss the design space — not lobbying for any specific implementation here.
