The escalation predicate + then routes to ESCALATE (competence class) instead of the + UNKNOWN bucket that costs a wasted same-tier retry. The + synthesised flag is captured on the Phase 4 row so analysts + can distinguish worker-reported from dispatcher-inferred + outcomes. Always-on when `IMPLEMENTER_ESCALATION_ENABLED=1`. + + - **Diff-aware gate parser** (`tools/_diff_aware_gate.py`): + pure-Python classifier that takes `local_ci_gate.sh` output + + the PR's changed-file list and splits failing BDD scenarios + into "related to your diff" vs. "unrelated" buckets. The + feature-stem heuristic catches the common case + (`features/auto_debug_cli_coverage.feature` ↔ + `src/cleveragents/auto_debug/cli.py`). Used directly by the + flaky pre-flight; available as a standalone helper for the + worker. + + - **Flaky-test pre-flight** (`tools/_implementer_gate_preflight.py`): + when `IMPLEMENTER_DISPATCHER_GATE_PREFLIGHT=1` is set, the + dispatcher runs `local_ci_gate.sh --fast` against the + pre-cloned worktree TWICE before handing the prompt to the + worker. Only the persistent failures (intersection of run 1 + and run 2) are surfaced — flaky failures that cleared on + retry are filtered out. The classified-as-unrelated bucket + carries an explicit "Do NOT bail" instruction the worker can + cite. Off-by-default. Cost: ~6 min of dispatcher wallclock + per cycle, buys back significantly more (Tier 0 stops bailing + on flaky unrelated failures). The motivating production case + (PR #30 Run 1) is captured as a regression test. + + - **Compliance gap detector** (`tools/_implementer_compliance.py`): + deterministic check of the four PR Compliance Checklist items + against the pre-cloned worktree — worktree clean, + `CHANGELOG.md [Unreleased]` non-empty, `CONTRIBUTORS.md` + contains the author email, HEAD commit has `ISSUES CLOSED:` + footer. Result is embedded in the worker prompt as a + "Compliance gap report (deterministic)" stanza. When all + gaps are closed, the agent's instruction is to emit + `{"outcome": "resolved", ...}` without re-touching the code; + when some are open, per-gap fill-in hints are inlined. + Activated alongside `IMPLEMENTER_ESCALATION_ENABLED=1`. + + Both prompt stanzas (gate pre-flight, compliance gap) are + appended via `_append_deterministic_stanzas` in + `_prefetch_prompt`. They're independently gated and skipped in + dry-run / when no preclone worktree exists. Flag-off path is + byte-equivalent to the pre-feature build. + - **In-cycle tier escalation for the implementer dispatcher (2026-05-12).** Replaces the cross-cycle `auto/last-attempt-tier-N` scheme planned in `auto-agents-tier-2-3-plan.md § Phase 5c` with a diff --git a/tests/auto_agents/test_diff_aware_gate.py b/tests/auto_agents/test_diff_aware_gate.py new file mode 100644 index 000000000..b3731a267 --- /dev/null +++ b/tests/auto_agents/test_diff_aware_gate.py @@ -0,0 +1,181 @@ +"""Unit tests for ``tools/_diff_aware_gate.py``. + +The classifier is pure-function — every test here constructs a +synthetic ``gate_output`` string + a synthetic ``changed_files`` +list and asserts the classification dict has the expected shape. + +The load-bearing motivating case (PR #30 Run 1, 2026-05-12) is +captured as a named regression test: gpt-5-mini ran ``--fast``, +the unit_tests gate failed with 6 BDD scenarios that were all in +CLI-related feature files (``automation_profile_cli.feature``, +``cli_extensions.feature``, ``cli_output_formats.feature``, +``plan_cli_commands_r2.feature``, ``plan_cli_coverage_boost.feature``, +``plan_prompt_command.feature``), and the PR's actual diff only +touched ``src/cleveragents/langgraph/graph.py`` (a LangGraph +subscription fix).
