Subject: [PATCH] fix: Reduce false positives in auto-label and duplicate
 detection

Auto-Label (agents-auto-label.yml):
- Now applies only the BEST matching label instead of all labels above threshold
- Prevents issues from getting multiple conflicting labels like bug+enhancement
- Other high-confidence matches moved to suggestions comment

Duplicate Detection (agents-dedup.yml):
- Raised threshold from 0.85 to 0.92 for higher precision
- Added title word overlap filter (requires 40% overlap or 95% score)
- Reduces false positives from issues in same domain that share vocabulary
- Logs filtering decisions for debugging

Test results showed:
- Suite C had 50% false positive rate (4/4 flagged, expected 2/4)
- Suite D applied both bug+enhancement to all issues

Fixes identified in Manager-Database #243-248 testing.

+## Immediate Next Steps (Based on Test Results)
+
+### 🔴 High Priority Fixes Needed
+
+**1. Fix Suite C: Duplicate Detection - 50% False Positive Rate**
+- **Problem:** All 4 test issues got `duplicate` label, but only 2 were actual duplicates
+- **Root Cause:** Similarity threshold too low or matching too aggressive
+- **Action:** Review `issue_dedup.py` similarity threshold, currently flagging unrelated issues
+- **Files:** `scripts/issue_dedup.py`, `.github/workflows/agents-dedup.yml`
+
+**2. Fix Suite D: Auto-Label Over-Labeling**
+- **Problem:** Both issues got BOTH `bug` and `enhancement` labels instead of the most appropriate one
+- **Root Cause:** Applying all labels above threshold instead of best match only
+- **Action:** Modify `label_matcher.py` to apply only the highest-scoring label
+- **Files:** `scripts/label_matcher.py`, `.github/workflows/agents-auto-label.yml`
+
+**3. Investigate Suite A #237 Workflow Failure**
+- **Problem:** "Add database migration for user roles" workflow failed
+- **Action:** Check workflow logs, identify error cause
+- **Issue:** Manager-Database #237
+
+### 🟡 Medium Priority
+
+**4. Review Suite A Capability Check Accuracy**
+- #236 (Stripe) should have been flagged as BLOCKED but wasn't
+- #239 (Logging) got `agent:needs-attention` when it should have proceeded
+- May need prompt tuning in `capability_check.py`
+
+**5. Review Suite B Decomposition Quality**
+- PRs #249, #250, #251 were created successfully
+- Need to manually review decomposition quality
+- Verify sub-tasks are actionable and appropriately sized
+
+---
+
+## Issue Fixed: Verifier Workflows ✅
+
+**Problem:** Multiple verifier issues:
+1. `verify:compare` and `verify:evaluate` not posting comments (rate limits + bespoke implementations)
+2. `verify:create-issue` creating TWO duplicate issues instead of one
+3. Rate limits in "Build verifier context" step
+
+**Root Causes:**
+- Bespoke verifier implementations instead of using reusable workflow
+- Both `agents-verify-to-issue.yml` AND `agents-verify-to-issue-v2.yml` triggering on same label
+- No rate limit handling in context builder step
+
+**Solutions Applied (PRs #715, #720, #726):**
+1. **PR #715:** Switched to thin caller pattern using `reusable-agents-verifier.yml`
+2. **PR #720:** Added rate limit handling in CI wait step (3 consecutive failures → skip)
+3. **PR #726:** 
+   - Disabled duplicate workflow with `if: false &&` condition (keeps file, satisfies Agents Guard)
+   - Added rate limit handling in context builder step
+   - Renamed to "Create Issue from Verification (DEPRECATED)"
+
+**Test Results (January 10, 2026):**
+| Test | Result | Evidence |

+### Test Suite Execution Status
+
+#### What Was Built (PRs #696-699)
+
+The Codex agent created **tooling infrastructure** rather than executing the functional tests:
+
+| PR | Issue | Files Created | Purpose |
+|----|-------|--------------|---------|
+| #699 | #690 (Suite A) | `run_consumer_repo_tests.py` (102 lines) | Runner to execute tests in consumer repos |

+| | | Enhanced `test_capability_check.py` (60 tests) | Unit test coverage |
+| #696 | #691 (Suite B) | Enhanced `task_decomposer.py` | Decomposition improvements |
+| | | Enhanced `test_task_decomposer.py` (64 tests) | Unit test coverage |
+| #697 | #692 (Suite C) | `issue_dedup_smoke.py` (588 lines) | CLI tool to create/check duplicate issues |
+| | | `test_issue_dedup_smoke.py` (24 tests) | Unit tests for smoke tool |
+| #698 | #693 (Suite D) | Enhanced `label_matcher.py` | Auto-label improvements |
+| | | Enhanced `test_label_matcher.py` (19 tests) | Unit test coverage |
+
+**Total New Code:** ~1,200 lines of tooling + 167 unit tests (164 pass, 3 skip)
+
+#### What Remains: Functional Test Execution
+
+**Functional tests EXECUTED on January 10, 2026.** 12 test issues created in Manager-Database:
+
+| Suite | Status | Issues | Results |
+|-------|--------|--------|---------|
+| A | ✅ EXECUTED | #236, #237, #239 | 1 success, 1 workflow error, 1 flagged correctly |
+| B | ✅ EXECUTED | #240, #241, #242 | All 3 success - PRs #249, #250, #251 created |
+| C | ⚠️ NEEDS TUNING | #243, #244, #245, #246 | 4/4 flagged duplicate (expected 2/4) - 50% false positive |
+| D | ⚠️ NEEDS TUNING | #247, #248 | Both got bug+enhancement (expected specific) |
+
+The smoke test tool (`issue_dedup_smoke.py`) can be used to automate Suite C testing:
+```bash
+# Create duplicate issue
+python scripts/issue_dedup_smoke.py --repo stranske/Manager-Database --source-issue 133 --title-suffix " (dup test)"
+
+# Verify detection
+python scripts/issue_dedup_smoke.py --repo stranske/Manager-Database --check-issue <NEW_ISSUE> --expected-issue-number 133

 #### Test Suite A: Capability Check
 **Workflow:** `agents-capability-check.yml`  
-**Test Issues Created:** Manager-Database #227
+**Test Issues Created:** Manager-Database #236, #237, #239 ✅
 
-| Test | Issue Title | Expected Behavior | Success Criteria |
-|------|-------------|-------------------|------------------|
-| A1 | Integrate Stripe Payment Processing | 🚫 BLOCKED - external API | `needs-human` label added, blocker explanation posted |
-| A2 | Add database migration for user roles | 🚫 BLOCKED/⚠️ REVIEW - infrastructure | Flags manual requirement |
-| A3 | Refactor logging to structured format | ✅ PROCEED - code-only | No `needs-human`, agent proceeds |
+| Test | Issue | Title | Expected | Actual | Result |
+|------|-------|-------|----------|--------|--------|
+| A1 | #236 | Integrate Stripe Payment Processing | 🚫 BLOCKED | Workflow ran successfully, no blocker label | ⚠️ NEEDS REVIEW |
+| A2 | #237 | Add database migration for user roles | 🚫 BLOCKED | Workflow **FAILED** (error) | ❌ FAILURE |
+| A3 | #239 | Refactor logging to structured format | ✅ PROCEED | `agent:needs-attention` label added | ⚠️ UNEXPECTED |
 
-**Execution Steps:**
-1. Create 3 test issues in Manager-Database with content from test plan
-2. Add `agent:codex` label to each
-3. Verify workflow runs and posts capability report
-4. Check correct labels applied (`needs-human` for A1/A2, not for A3)
-5. Document results in langchain-post-code-rollout.md
+**Analysis:**
+- Workflow is triggering correctly on `agent:codex` label
+- #236 ran but didn't flag the Stripe integration as blocked (may need prompt tuning)
+- #237 had a workflow execution error - needs investigation
+- #239 got `agent:needs-attention` instead of proceeding cleanly - needs review

-**Execution Steps:**
-1. Create 3 test issues with varying complexity
-2. Add `agents:decompose` label
-3. Verify sub-task checklist posted as comment
-4. Verify label removed after posting
-5. Assess quality: Are sub-tasks specific and actionable?
+**Analysis:**
+- ✅ All 3 workflows ran successfully
+- ✅ PRs created automatically with decomposed tasks
+- ✅ Labels processed correctly (`agents:decompose` triggered workflow)
+- Need to review PR contents to verify decomposition quality
 
 #### Test Suite C: Duplicate Detection
 **Workflow:** `agents-dedup.yml`  
-**Test Issues Created:** Manager-Database #229
-
-| Test | Issue Title | Similarity To | Expected Result |
-|------|-------------|---------------|-----------------|
-| C1 | Add GET endpoint for all managers | Existing #133 | ⚠️ DUPLICATE warning |
-| C2 | Add PUT endpoint to update manager | Related but different | ✅ NO FLAG |
-| C3 | Implement caching layer | Unrelated | ✅ NO FLAG |
-| C4 | Get list of all managers from database | Same as C1, different words | ⚠️ DUPLICATE |
-
-**Success Metrics:**
-- True positive rate: ≥90% (C1, C4 correctly flagged)
-- False positive rate: <10% (C2, C3 not flagged)
-
-**Execution Steps:**
-1. Create 4 test issues (automatically triggers workflow)
-2. Check for duplicate warning comments
-3. Verify correct issues linked
-4. Calculate accuracy metrics
+**Test Issues Created:** Manager-Database #243, #244, #245, #246 ✅
+**Tooling Available:** `scripts/issue_dedup_smoke.py` can automate this suite
+
+| Test | Issue | Title | Expected | Actual | Result |
+|------|-------|-------|----------|--------|--------|
+| C1 | #243 | Add GET endpoint for all managers | ⚠️ DUPLICATE of #133 | `duplicate` label added | ✅ TRUE POSITIVE |
+| C2 | #244 | Add PUT endpoint to update manager | ✅ NO FLAG | `duplicate` label added | ❌ FALSE POSITIVE |
+| C3 | #245 | Implement caching layer | ✅ NO FLAG | `duplicate` label added | ❌ FALSE POSITIVE |
+| C4 | #246 | Get list of all managers from database | ⚠️ DUPLICATE | `duplicate` label added | ✅ TRUE POSITIVE |
+
+**Accuracy Metrics:**
+- True positive rate: 100% (2/2 duplicates correctly flagged)
+- False positive rate: **100%** (2/2 non-duplicates incorrectly flagged)
+- **Overall accuracy: 50%** - NEEDS TUNING
+
+**Analysis:**
+- Workflow is triggering and running successfully
+- Similarity threshold may be too low (catching too many)
+- Need to review the similarity scores and adjust threshold
+- All 4 issues got `duplicate` label despite only 2 being actual duplicates
 
 #### Test Suite D: Auto-Label
 **Workflow:** `agents-auto-label.yml`  
-**Test Issues Created:** Manager-Database #230
+**Test Issues Created:** Manager-Database #247, #248 ✅
+
+| Test | Issue | Title | Expected | Actual | Result |
+|------|-------|-------|----------|--------|--------|
+| D1 | #247 | Fix crash when database connection fails | `bug` only | `bug` + `enhancement` | ⚠️ OVER-LABELED |
+| D2 | #248 | Add support for bulk manager import | `enhancement` only | `bug` + `enhancement` | ⚠️ OVER-LABELED |
 
-| Test | Issue Title | Expected Labels |
-|------|-------------|-----------------|
-| D1 | Fix crash when database connection fails | `bug` |
-| D2 | Add support for bulk manager import | `enhancement` |
+**Accuracy Metrics:**
+- Correct label applied: 100% (both got expected label)
+- Extra labels applied: 100% (both got extra label)
+- **Specificity: POOR** - workflow is too aggressive
 
-**Execution Steps:**
-1. Create 2 unlabeled issues
-2. Verify workflow runs automatically
-3. Check if labels suggested/applied
-4. Verify accuracy of label matching
+**Analysis:**
+- Workflow is triggering and running successfully
+- Both bug AND enhancement labels applied to every issue
+- Label matching threshold too permissive
+- Need to tune to apply only the BEST matching label, not all matches
 
-**Time Estimate:** 2-3 days (8 issues × 15-20 min each + documentation)
+**Time Estimate:** ~~2-3 days~~ **COMPLETED January 10, 2026** - Execution done, tuning needed
