After `apm experimental enable contracts`, the consumer +selects the file with `apmx --from`. + +Contract frontmatter declares fixed-file `needs`, one regular-file `produces`, +1 to 8 named shell commands in `verify`, and optionally one skill in `imports`. +The nonempty Markdown body describes the work. Inputs come from the caller, +not package sample files; checks come from the package. + +Declare the imported skill in `apm.yml`: only one self-contained root `SKILL.md` +is supported. `apmx` can fetch it privately if missing, without user installation +or harness activation. No companions, transitive dependencies, MCP/hooks/plugins, +`run`, `budget`, `sandbox`, or composition are supported. + +See the canonical [source and import reference](https://microsoft.github.io/apm/reference/cli/plan/#contract-source) +and [commands](./commands.md#local-contracts-v01). + ## Canvas extensions (experimental, Copilot-only) Behind the `canvas` experimental flag (`apm experimental enable canvas`), a diff --git a/pyproject.toml b/pyproject.toml index 00b88a5720..864303048a 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -61,6 +61,7 @@ build = [ [project.scripts] apm = "apm_cli.cli:main" +apmx = "apm_cli.apmx:main" [tool.setuptools.packages.find] where = ["src"] diff --git a/scripts/architecture_linter/checks/contract_leaf_runtime.py b/scripts/architecture_linter/checks/contract_leaf_runtime.py new file mode 100644 index 0000000000..406df5d024 --- /dev/null +++ b/scripts/architecture_linter/checks/contract_leaf_runtime.py @@ -0,0 +1,98 @@ +"""Keep leaf contracts outside legacy fallback and duplicate authorities.""" + +from scripts.architecture_linter.facts import FactsProvider +from scripts.architecture_linter.groups.common import checked_facts, inventory_paths, violation +from scripts.architecture_linter.models import Rule, Violation + +RULE_ID = "contracts-leaf-runtime-owners" +PREFIX = "src/apm_cli/contracts/" +ENTRY_PREFIXES = ("src/apm_cli/apmx.py", "src/apm_cli/install/contract_source") +GUARDS = ( + "contracts-leaf-source", + "contracts-leaf-subject", + "contracts-leaf-process", + "contracts-leaf-outcome", + "contracts-package-source", +) + + +def check_contract_owners(provider: FactsProvider) -> tuple[Violation, ...]: + """Reject dangerous bypasses using the existing shared syntax facts.""" + findings: list[Violation] = [] + for path in inventory_paths( + provider, prefixes=(PREFIX, *ENTRY_PREFIXES, "src/apm_cli/core/contract_logger.py") + ): + if not path.endswith(".py"): + continue + facts, failures = checked_facts(provider, path, RULE_ID, require_python=True) + findings.extend(failures) + if failures: + continue + for imported in facts.imports: + if (imported.module and imported.module.rsplit(".", 1)[-1] == "script_runner") or any( + name in {"ScriptRunner", "PromptCompiler"} for name in imported.names + ): + findings.append( + violation( + RULE_ID, + path, + "Contracts must not enter legacy prompt discovery, installation or compilation.", + line=imported.line, + ) + ) + for call in facts.calls: + name = call.qualname.rsplit(".", 1)[-1] + message = None + if name == "Popen" and path != PREFIX + "process.py": + message = "Managed contract child creation belongs to contracts/process.py." + elif name == "compute_file_hash": + message = "Exact contract subjects must not use normalized deployment hashes." + elif name in {"ScriptRunner", "PromptCompiler", "get_best_available_runtime"}: + message = ( + "Contracts require explicit source/runtime selection without legacy fallback." + ) + elif path.startswith(ENTRY_PREFIXES) and name in { + "run_install_pipeline", + "InstallService", + }: + message = ( + "Contract source preparation must not activate the project install pipeline." + ) + elif path.startswith(ENTRY_PREFIXES) and call.qualname in { + "subprocess.run", + "subprocess.check_call", + "subprocess.check_output", + "os.system", + }: + message = ( + "Contract entrypoints delegate transport and execution to existing owners." + ) + elif path == "src/apm_cli/apmx.py" and name == "Choice": + message = "Contract harness capability admission belongs to the runtime owner." + if message: + findings.append(violation(RULE_ID, path, message, line=call.line)) + for definition in facts.definitions: + if ( + definition.name in {"normalize_check", "reduce_outcome", "native_assurance_limited"} + and path != PREFIX + "records.py" + ): + findings.append( + violation( + RULE_ID, + path, + "Contract check normalization, outcomes and assurance limits belong to records.py.", + line=definition.line, + ) + ) + return tuple(findings) + + +RULES = ( + Rule( + id=RULE_ID, + group="contracts_tests", + guard_ids=GUARDS, + description="Leaf source, exact subjects, process supervision and outcomes keep canonical owners.", + check=check_contract_owners, + ), +) diff --git a/scripts/architecture_linter/groups/contracts_tests.py b/scripts/architecture_linter/groups/contracts_tests.py index a5713ada51..b3aa0bfd67 100644 --- a/scripts/architecture_linter/groups/contracts_tests.py +++ b/scripts/architecture_linter/groups/contracts_tests.py @@ -8,10 +8,11 @@ module size budget; they own no RULES of their own.
