aethis-cli 0.3.0

CLI for the Aethis developer API — author, test, and publish rule bundles

aethis-cli

CLI for the Aethis developer API — evaluate eligibility, author rule bundles, and publish from the terminal.

Install

pip install aethis-cli

Quick start

No sign-up needed. Decision tools work immediately.

# Evaluate eligibility against a published bundle
aethis decide -b <bundle_id> -i '{"space.crew.age": 35, "space.medical.cert_valid": true}'

# Inspect the input fields a bundle expects
aethis fields -b <bundle_id>

# Get human-readable rule descriptions
aethis explain -b <bundle_id>

Author your own rules

Rule authoring is invite-only private beta. Decision tools (aethis decide, aethis fields, aethis explain) work immediately with no sign-up — this section is for approved beta tenants. Request access →

# 1. Authenticate (creates a key via browser sign-in)
aethis account generate
# Or paste an existing key: aethis login

# 2. Initialise a project
mkdir my-rules && cd my-rules
aethis init

# 3. Add source documents and guidance
#    (put PDFs/text in .aethis/sources/, hints in .aethis/guidance/hints.yaml)

# 4. Generate a rule bundle
aethis generate

# 5. Run test cases
aethis test

# 6. Publish the bundle
aethis publish

Try the example

A complete, runnable example is included in examples/spacecraft-crew-rules/:

cp -r examples/spacecraft-crew-rules my-first-rules && cd my-first-rules
aethis account generate
aethis generate --poll
aethis test
aethis decide -i '{"space.crew.species": "Human", "space.crew.age": 35, "space.crew.flight_hours": 600, "space.crew.has_pilot_license": true, "space.crew.has_gaa_exam": true, "space.medical.cert_valid": true, "space.mission.type": "suborbital", "space.crew.has_towel": true}'

Project structure

After aethis init, your project looks like:

my-rules/
  .aethis/
    aethis.yaml          # project config
    state.json           # tracked IDs (project, bundle, job)
    sources/             # PDF/text source documents
    guidance/
      hints.yaml         # guidance hints for the code synthesizer
    tests/
      scenarios.yaml     # golden test cases

aethis.yaml

project: my-rules
api_key_env: AETHIS_API_KEY
base_url: https://api.aethis.ai

scenarios.yaml

tests:
  - name: "Eligible — all requirements met"
    inputs:
      space.crew.age: 35
      space.crew.flight_hours: 600
      space.crew.has_pilot_license: true
    expect:
      outcome: eligible
  - name: "Not eligible — no medical cert"
    inputs:
      space.medical.cert_valid: false
    expect:
      outcome: not_eligible

Environment variables

Variable	Description	Required	Default
AETHIS_API_KEY	Your API key (ak_live_...)	Authoring only	—
AETHIS_BASE_URL	API base URL	No	https://api.aethis.ai
AETHIS_CLERK_DOMAIN	Clerk domain override (development only)	No	clerk.aethis.legal

Extending with plugins

aethis-cli discovers third-party plugins via Python entry points under the aethis_cli.plugins group. A plugin is any installed package that exposes a register(app: typer.Typer) -> None callable; at startup the CLI calls it with the root Typer app and the plugin attaches extra commands.

Example pyproject.toml:

[project.entry-points."aethis_cli.plugins"]
my_plugin = "my_package.plugin:register"

Example my_package/plugin.py:

import typer

def register(app: typer.Typer) -> None:
    @app.command()
    def hello() -> None:
        typer.echo("hello from my plugin")

Staff-only tools (DSL source viewer, IAM registry, domain-guidance management, --base-url override) live in the private aethis-cli-internal package, installed on request.

Development

git clone https://github.com/aethis-ai/aethis-cli.git
cd aethis-cli
pip install -e ".[dev]"
pytest tests/ -v

Shell completions

# Install tab completion for your shell
aethis --install-completion bash   # or zsh, fish, powershell

Troubleshooting

aethis generate times out but server continues The server finishes even if your client disconnects. Wait 10–15 min, then run aethis bundles list — if the bundle appeared, run aethis test and aethis publish. Do not re-trigger generation; that creates a duplicate run.

aethis publish fails with "tests are failing" publish refuses a bundle with failing tests. Fix with guidance + regenerate, or pass --force (not recommended for production).

422 Validation error on aethis decide DATE fields must be passed as integer ordinals, not ISO strings. 2025-04-13 → 739354:

python3 -c "from datetime import date; print(date(2025,4,13).toordinal())"

Auth error: … Your API key is missing, expired, or revoked. Run aethis login to paste a new one, or aethis account generate to create one.

403 Forbidden: missing scope Your key lacks the required scope for the command. aethis whoami shows what your current key can do. Contact support to upgrade scopes.
