Agents do not need
more chatter.
They need signaling.

`bca2p` gives agent systems the coordination mechanics biology solved long ago: receptors, scoped signals, temporary complexes, quorum, feedback, and homeostasis. The result is sharper routing, better debugging, and far less communication drift.

The actual problem

Current multi-agent stacks coordinate workflows well, but they still communicate like improvised chat threads.

Routing becomes opaque

You can see that a message moved, but not why that route was chosen or whether it was biologically sensible.

Signal meaning drifts

Generic messages force agents to infer intent from natural language instead of matching explicit receptor contracts.

Scale creates sprawl

Adding more agents usually means more hand-authored branches, more manual filters, and more brittle coordination logic.

Stability is ad hoc

Noise, retries, escalation storms, and sender overload are often handled after the fact rather than within the communication model.

Nature-inspired coordination

Nature solved coordination long ago. `bca2p` replaces chaotic agent chat with the precision of biological signaling.

Specific receptors, not vague prompts

Scoped signaling across local and global layers

Temporary complexes for real coordination

Quorum and homeostasis built into the model

Causal feedback instead of opaque traces

Replayable behavior, not one-off magic

Signaling modes

Stop forcing every interaction into a chat thread.

Autocrine

Self-regulation loops

An agent can reflect, stabilize, and repair its own local state without broadcasting every intermediate decision.

Paracrine

Local team coordination

Send context to a relevant neighborhood of agents instead of turning every task into a global fan-out event.

Endocrine

System-wide directives

Broadcast a policy shift, mission update, or urgent goal across the whole organism when the change truly matters.

Juxtacrine

Contact-dependent handoff

Use direct, trusted exchange when two agents need high-bandwidth coordination with strict interface guarantees.

Synaptic

Persistent weighted links

Maintain fast repeat pathways between agents that work well together, rather than rediscovering the route every run.

Quorum

Threshold-based action

Wait for enough evidence, votes, or agreement before changing system behavior, escalating, or committing resources.

Comparison snapshot

Not another API—a completely new theory of communication.

Most frameworks start from orchestration and layer messaging on top. `bca2p` starts from signaling semantics and builds coordination around them.
