From 2cb82f8acc6ec1bd01609e333430d6e6eb02ea41 Mon Sep 17 00:00:00 2001 From: Jeffrey Phillips Freeman Date: Thu, 2 Apr 2026 09:15:24 +0000 Subject: [PATCH] feat(autonomy): E2E porting task completes autonomously MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements M7 (v3.6.0) acceptance criterion: an end-to-end porting task completes autonomously using the full CleverAgents pipeline. Changes: - Add reproducible E2E porting task fixture (examples/actions/e2e-porting.yaml) with invariants, typed arguments, and supervised automation profile - Add E2EPortingService that ties together ACMS context assembly, plan lifecycle (Strategize → Execute → Apply), subplan decomposition, correction engine, and apply phase - Add validate_ported_output() for Python 3 syntax, type annotation, and Python 2 construct checks - Add _apply_stub_porting() deterministic Python 2→3 transformation for test path (no LLM required) - Add Behave BDD tests (features/e2e_porting_task.feature) covering fixture validation, action registration, plan lifecycle, output validation, and lifecycle observability - Add Robot Framework E2E acceptance test (robot/e2e/m7_e2e_porting.robot) covering all M7 acceptance criteria Closes #857 --- examples/actions/e2e-porting.yaml | 66 ++ features/e2e_porting_task.feature | 179 +++++ features/steps/e2e_porting_task_steps.py | 470 +++++++++++++ robot/e2e/m7_e2e_porting.robot | 258 +++++++ .../services/e2e_porting_service.py | 653 ++++++++++++++++++ 5 files changed, 1626 insertions(+) create mode 100644 examples/actions/e2e-porting.yaml create mode 100644 features/e2e_porting_task.feature create mode 100644 features/steps/e2e_porting_task_steps.py create mode 100644 robot/e2e/m7_e2e_porting.robot create mode 100644 src/cleveragents/application/services/e2e_porting_service.py diff --git a/examples/actions/e2e-porting.yaml b/examples/actions/e2e-porting.yaml new file mode 100644 index 000000000..bd6767ca5 --- /dev/null +++ b/examples/actions/e2e-porting.yaml @@ -0,0 +1,66 @@ +# ============================================================================ +# E2E Porting Action — Reproducible End-to-End Porting Task Fixture +# ============================================================================ +# Defines a complete porting task that exercises the full CleverAgents +# pipeline: ACMS context assembly, plan lifecycle, subplan decomposition, +# correction engine, and apply phase. +# +# This fixture is used by M7 (v3.6.0) acceptance tests to validate that +# an end-to-end porting task completes autonomously. +# +# Create: agents action create --config examples/actions/e2e-porting.yaml +# ============================================================================ + +name: local/e2e-porting +description: "Port a Python 2 module to Python 3 with type annotations" +long_description: | + Ports a small Python 2 source module to Python 3, adding: + - Python 3 compatible syntax (print function, division, unicode) + - PEP 484 type annotations on all public functions + - Docstrings for all public symbols + - A companion test module verifying the ported code + + This action exercises the full CleverAgents autonomous pipeline: + ACMS context assembly, plan lifecycle, subplan decomposition, + correction engine, and apply phase. + +strategy_actor: local/strategist +execution_actor: local/executor + +definition_of_done: | + The porting task is complete when: + 1.
