chore: delete orphaned _templates/ai_validation folder and related test assertions

[mickume]

Summary

The folder packages/agentfox/agentfox/_templates/ai_validation/ contains four orphaned prompt templates that are not loaded or referenced by any code:

• generate_test_spec.md
• stale_dep.md
• rewrite_criteria.md
• acceptance_criteria.md

These were left behind when the legacy ai_validation.py module was deleted as part of spec 137. The module itself is gone, but its companion templates were not cleaned up.

What to do

1. Delete packages/agentfox/agentfox/_templates/ai_validation/ and all files in it.
2. Remove the test class and assertions in packages/agentfox/tests/spec/test_137_legacy_removal.py that reference ai_validation (lines ~376–385, ~511), since the thing they guard against is being deleted in the same change.
3. Run make check to confirm no regressions.

Context

Discovered by grepping for consumers of the templates — none exist. The only references are in test_137_legacy_removal.py, which asserts that ai_validation.py does not exist (i.e., it tests the deletion, not the feature). Once the templates folder is also removed, those assertions have no purpose.

Triage Report

Summary: When ai_validation.py was deleted from agentfox/spec/ during the spec 137 legacy cleanup, its companion prompt templates in agentfox/_templates/ai_validation/ were not removed. Those four .md files (generate_test_spec.md, stale_dep.md, rewrite_criteria.md, acceptance_criteria.md) are now orphaned: no code loads or references them. Separately, test_137_legacy_removal.py contains a TestAiValidationDeleted class (lines 381-385) that asserts ai_validation.py is absent, and TestNoDeletedModuleImportsInTests (line 511) includes a regex branch guarding against re-importing ai_validation. Both assertions were written to verify the original deletion; once the templates folder is also removed, TestAiValidationDeleted has no purpose, and the ai_validation branch in the import-guard regex becomes dead weight.

Affected files:

• packages/agentfox/agentfox/_templates/ai_validation/acceptance_criteria.md
• packages/agentfox/agentfox/_templates/ai_validation/generate_test_spec.md
• packages/agentfox/agentfox/_templates/ai_validation/rewrite_criteria.md
• packages/agentfox/agentfox/_templates/ai_validation/stale_dep.md
• packages/agentfox/tests/spec/test_137_legacy_removal.py

Acceptance Criteria

AC-1: The _templates/ai_validation/ directory and all four files inside it are removed from the repository.

• Preconditions: The directory packages/agentfox/agentfox/_templates/ai_validation/ exists and contains four tracked .md files.
• Expected: git ls-files packages/agentfox/agentfox/_templates/ai_validation/ returns no output.
• Assertion: Run git ls-files packages/agentfox/agentfox/_templates/ai_validation/ and assert the output is empty; also confirm the directory does not exist on disk via ls packages/agentfox/agentfox/_templates/ai_validation/ 2>&1 returning a 'No such file' error.

AC-2: The TestAiValidationDeleted class and its single test method are removed from test_137_legacy_removal.py.

• Preconditions: test_137_legacy_removal.py contains class TestAiValidationDeleted with method test_ai_validation_does_not_exist starting around line 381.
• Expected: Neither the class name TestAiValidationDeleted nor the method test_ai_validation_does_not_exist appear anywhere in test_137_legacy_removal.py.
• Assertion: Run grep -n 'TestAiValidationDeleted\|test_ai_validation_does_not_exist' packages/agentfox/tests/spec/test_137_legacy_removal.py and assert it produces no output.

AC-3: The ai_validation branch of the deleted-imports regex in TestNoDeletedModuleImportsInTests is removed from test_137_legacy_removal.py.

• Preconditions: Line ~511 of test_137_legacy_removal.py contains the literal string from agent_fox\.spec\.ai_validation import as part of a compiled regex pattern.
• Expected: No occurrence of the string 'ai_validation' remains anywhere in test_137_legacy_removal.py.
• Assertion: Run grep -n 'ai_validation' packages/agentfox/tests/spec/test_137_legacy_removal.py and assert it produces no output.

AC-4: No other source or test file outside of test_137_legacy_removal.py references the ai_validation templates directory or the string 'ai_validation'.

• Preconditions: Before the fix, only test_137_legacy_removal.py and the template files themselves contain the string 'ai_validation'.
• Expected: After deletion, a recursive grep for 'ai_validation' across the packages/ tree returns no results.
• Assertion: Run grep -rn 'ai_validation' packages/agentfox/ and assert it produces no output.

AC-5: make check passes with no regressions after the cleanup.

• Preconditions: make check passed before the change; the deleted test class and regex branch are the only changes to test_137_legacy_removal.py.
• Expected: make check exits with code 0 and the test suite reports no failures.
• Assertion: Run make check and verify exit code is 0 and no test is reported as FAILED or ERROR.

Fix Review Report

Overall verdict: PASS

Summary: All five acceptance criteria are satisfied. The ai_validation templates directory and its four files are deleted from the repository. The TestAiValidationDeleted class and the ai_validation regex branch were cleanly removed from test_137_legacy_removal.py. No references to 'ai_validation' remain anywhere in packages/agentfox/. The changed file passes lint and all directly relevant tests. make check has pre-existing failures (4 import-sorting lint errors in unmodified files, hypothesis flaky tests) that are not caused by this commit — no regressions introduced.

Per-criterion verdicts

• ✅ NS-REQ-1.1: PASS
  • Evidence: git ls-files packages/agentfox/agentfox/_templates/ai_validation/ returns no output. ls of the directory returns 'No such file or directory'. The commit deleted all four .md files: acceptance_criteria.md, generate_test_spec.md, rewrite_criteria.md, stale_dep.md.
• ✅ NS-REQ-2.1: PASS
  • Evidence: grep -n 'TestAiValidationDeleted|test_ai_validation_does_not_exist' packages/agentfox/tests/spec/test_137_legacy_removal.py returns no output (exit code 1). The diff confirms the class TestAiValidationDeleted and its method test_ai_validation_does_not_exist (lines 378-383) were removed.
• ✅ NS-REQ-3.1: PASS
  • Evidence: grep -n 'ai_validation' packages/agentfox/tests/spec/test_137_legacy_removal.py returns no output (exit code 1). The diff confirms the regex branch '|from agent_fox.spec.ai_validation import' was removed from the TestNoDeletedModuleImportsInTests pattern at line ~511, leaving only the 'from agent_fox.spec.validators' branch.
• ✅ NS-REQ-4.1: PASS
  • Evidence: grep -rn 'ai_validation' packages/agentfox/ returns no output (exit code 1). No source or test file anywhere in packages/agentfox/ references ai_validation.
• ✅ NS-REQ-5.1: PASS
  • Evidence: make check exits non-zero, but all failures are pre-existing and unrelated to this commit: (1) 4 ruff I001 import-sorting errors in test_reset_spec_props.py, test_watch_mode.py, test_hard_reset_props.py, test_workspace_integration.py — none modified by this commit; (2) test failures are hypothesis flaky tests and meta smoke tests that were already failing before this change. The changed file test_137_legacy_removal.py passes ruff with 'All checks passed!' and 31 of 32 tests pass — the sole failure is TestSmokeFullTestSuite which runs the entire suite as a subprocess and catches those same pre-existing failures. No regressions introduced by this commit.
