Advanced Autonomous Agent Executor (AAAX)

Advanced Autonomous Agent Executor (AAAX) is the PSI shell for package-shaped agent systems.

Use it to inspect a PsiHub package, mount its tactics and channels, bind local handlers, open a small FastAPI surface, and hand that surface to a human, script, coding agent, or another system. The feel is intentionally shell-like: name the package, see the resources, run one command, and get a callable system.

AAAX can also stand alone. A Strategy can be just a Pydantic-modeled resource table plus local handlers exposed through FastAPI. LLLM, SSSN, and PsiHub are optional bridges when you want tactic, channel, and package behavior.

$ aaax inspect packages/analyst-pack
analysis-pack: Demo analyst package.
package analysis-pack psi://demo/analysis-pack
tactic echo psi://demo/analysis-pack/tactics/echo
channel events psi://demo/analysis-pack/channels/events

$ aaax serve packages/analyst-pack --port 8400
Uvicorn running on http://127.0.0.1:8400

AAAX does not replace LLLM, SSSN, PsiHub, Codex, Claude Code, schedulers, sandboxes, or deployment platforms. It is the thin shell where those pieces are named, mounted, served, and handed off.

Install

python -m pip install aaax

For a reproducible install:

python -m pip install aaax==0.2.2

For local PSI composition:

python -m pip install "aaax[integrations]" lllm-core sssn psihub

Mount A PsiHub Package

If a folder contains psi.toml, AAAX can serve it directly:

aaax serve packages/analyst-pack --port 8400

AAAX reads the manifest and mounts:

• package metadata and card hints;
• schemas, tactics, services, runs, and config;
• SSSN channels and snapshots;
• docs, examples, and assets.

Python tactic entrypoints become /tactics/{name}/run. Channels are backed by a local SSSN store and exposed through /channels/{name}/events. Services that point at one tactic are invokable as resources.

curl -X POST http://127.0.0.1:8400/tactics/finance_baseline/run \
  -H 'content-type: application/json' \
  -d '{"input": {"records": []}, "context": {"request": "demo"}}'

Append and query channel events:

curl -X POST http://127.0.0.1:8400/channels/events/events \
  -H 'content-type: application/json' \
  -d '{"input": {"kind": "record", "payload": {"text": "hello"}}}'

curl http://127.0.0.1:8400/channels/events/events?limit=10

Write A Shell Script

For larger systems, write a strategy.py. A strategy is the shell script: it mounts packages, assigns local names, and optionally defines /run.

from aaax import Strategy


def build_strategy() -> Strategy:
    shell = Strategy(
        "analyst-shell",
        description="Mount source channels and analyst tactics.",
    )
    shell.use_package("packages/source-channels", prefix="sources")
    shell.use_package("packages/analyst-tactics", prefix="analysts")

    @shell.runner
    def run(input_value, *, context=None):
        return {
            "input": input_value,
            "resources": [resource.ref for resource in shell.resources],
            "context": context or {},
        }

    return shell

aaax serve strategy.py --port 8400
