ACES Scenario Packs

The canonical, shared home for the ACES scenario-pack definition and the authoring / validation tooling that goes with it, published as an installable Python package so catalogs (and others) consume one version-matched artifact instead of vendoring the contract.

This repository does not host scenario packs. Packs live in their own catalog repositories and consume this contract.

Install

pip install aces-scenario-packs

This provides the console tools plus the version-matched schemas and template:

• aces-pack-validate — validate pack content against the contract.
• aces-pack-release — boundary-split build, lint, release, and profile-smoke gate.
• aces-new-pack — scaffold a new pack from the bundled template.
• aces-pack-issue-skeleton — generate a pack work-issue skeleton.

Validate one pack by pointing the tools at its directory:

aces-pack-validate --pack ./scenarios/example-pack
aces-pack-release check --pack ./scenarios/example-pack

As a convenience, a directory containing only pack directories can be checked in one command. Every direct child directory is treated as a pack candidate:

aces-pack-validate --packs-root ./scenarios
aces-pack-release check --packs-root ./scenarios

Consumers can validate one immutably staged pack in-process, without Git, subprocesses, or pack-local code:

from aces_scenario_packs import validate_pack

result = validate_pack(pack_root)
if not result.ok:
    reject(result.errors)

This checks the static ingest contract: pack identity, required provenance and safety/review policy, an optional referenced compatibility manifest, and direct SDL documents through ACES. Diagnostics contain bounded error codes and relative locations, never source bodies or absolute paths. See Single-Pack Consumer Validation.

What's here

• Definition
  • docs/scenario-packs.md — what a scenario pack is.
  • Layout contract + schemas + template ship as package data under src/aces_scenario_packs/resources/ (contract/pack-layout.md, schemas/, template/).
  • Architecture Decision Records — purpose, packaging, build/release, SBOM.
• Tools — the package modules under src/aces_scenario_packs/, exposed as the console entry points above.

Boundary

This repository is subordinate to ACES core (aces-sdl): it exists to make authoring and shipping ACES scenarios easier, and defines no extensions to ACES semantics (ADR 0009).

• ACES core owns the Scenario Definition Language (SDL) and all scenario semantics. Where ACES owns a concept, packs consume it from ACES.
• This repository owns how a scenario pack is structured, authored, validated, and released — the layout and the tools that enforce it.
• Downstream catalogs hold the actual packs and any private runtime, delivery, or product integrations.

Development

python3 -m venv .venv
. .venv/bin/activate
pip install -e .

python -m unittest discover -s tests

Releases are managed by release-please — merge-driven, nothing hand-run (see ADR 0008). The version lives in pyproject.toml ([project].version) and is bumped by release-please; __version__ derives from it. The Conventional Commit PR title decides the bump:

You never edit CHANGELOG.md — release-please owns it. As feature PRs land on main (via dev), release-please keeps a chore(main): release X.Y.Z PR up to date with the version bump + changelog. Merge that PR to release: it tags vX.Y.Z, builds the sdist + wheel, generates a CycloneDX SBOM, publishes to PyPI via OIDC, and cuts the GitHub Release. (The release PR is opened by the CI token, so its checks don't auto-run — admin-merge it.) A CI check enforces conventional PR titles and bans agent-branding prefixes.
