WASM Sequential Agent Plugin

A sample TinyGo WASM module that implements sequential agent behavior: it runs all configured sub-agents in order, stopping on the first error.

ABI

The module imports host functions from the env module:

Import	Signature	Description
subagent_count	() → i32	Returns the number of sub-agents
run_subagent	(index i32) → i32	Runs sub-agent at index; returns 0 on success
subagent_name	(index i32, buf_ptr i32, buf_cap i32) → i32	Writes sub-agent name into buffer, returns length
log_msg	(ptr i32, len i32)	Logs a message to the host

The module exports:

Export	Signature	Description
execute	() → i32	Entry point; returns 0 on success
malloc	(size u32) → *byte	Memory allocator for host use
free	(ptr *byte)	Free memory (no-op)

Build

Requires TinyGo.

make build

Or manually:

tinygo build -o sequential.wasm -scheduler=none --no-debug -target wasi ./main.go

Usage in config.yaml

Reference the compiled .wasm file from your agent configuration:

agents:
  MySequentialWasm:
    type: wasm
    module_path: examples/wasm-sequential/sequential.wasm
    sub_agents:
      - StepOne
      - StepTwo
      - StepThree
