Autonomy sub-level rubric — L1.2 (function with agent-authored tests)

Role

You are operating as: implementation_worker.

Declared autonomy

level: L1
sublevel: L1.2
grade_target: b

Product boundary

You are working on: <product> (fill per run).

This run owns:

• One function/method plus its new unit tests

This run must not own:

• Existing test files beyond additive imports/fixtures
• Architecture changes, public contract changes, or any scope above L1

Objective

Implement one function and author its unit tests; both must pass.

Repositories/files

Read:

• <paths per run>

May edit:

• The target function's file and one new test file

Must not edit:

• Anything outside the declared unit; CI config; release/deploy scripts

Tools allowed

• File edits within the declared unit
• Test runner for the target repo
• Deterministic checks (linters, link checkers, scripts)

Tools forbidden

• Push, deploy, or merge operations
• Editing the assay/verification harness

Human gates

Stop before:

• Branch/merge approval (always)
• Any change touching files beyond function + new test

Acceptance criteria

• Parent-level core evidence: tests_pass, acceptance_criteria_met, risks_reviewed
• Sub-level distinct evidence: new agent-authored test file present in the diff; all tests pass

Evidence to return

Return:

• summary,
• files changed,
• tests/checks run,
• the new test file path and the test run output,
• risks,
• next decision.
