The separation of state (what happened) from presentation (how to show) works as designed +2. **Plumbing is solid** - All 5 layers integrate cleanly in the post-review pipeline +3. **Agent isolation works** - Agent remains context-free while post-scripts handle all memory operations +4. **100% duplicate elimination is possible** - On controlled test fixtures across 3 review rounds + +### What Was Tested + +**Test data:** Synthetic fixtures (`test-data/review/*.json`) designed to validate the architecture +- Round 1: 6 findings (all new) +- Round 2: 5 findings (3 still_present, 2 new) +- Round 3: 3 findings (2 dismissed, 1 new) + +**What this proves:** The implementation **can** deduplicate findings when semantic keys match and the pipeline executes correctly. + +**What this doesn't prove:** How well function-based semantic keys hold up on real agent output where: +- Function extraction is messier (complex codebases, nested functions, language quirks) +- Line numbers shift unpredictably (rebases, force-pushes, large refactors) +- Agent rephrases findings between rounds (LLM non-determinism) +- Edge cases occur (renames, code movement, file splits) + +### Next Steps for Production Validation + +To validate readiness for production integration, the experiment needs real data testing: + +1. **Pull actual agent output** from GitHub Actions artifacts on the reference issues: + - [#1500](https://github.com/fullsend-ai/fullsend/issues/1500) - 85% repetition rate + - [#1013](https://github.com/fullsend-ai/fullsend/issues/1013) - Same finding 6x + - [#2794](https://github.com/fullsend-ai/fullsend/issues/2794) - Identical protected-path comments + - [#1552](https://github.com/fullsend-ai/fullsend/issues/1552) - No context passed + +2. **Measure actual dedup rates** on real review iterations: + - What % of duplicates did semantic keys catch? + - What % were missed due to line shifts, function renames, or rephrasing? + - What edge cases broke the matching logic? + +3. **Document findings** with specific metrics: + - What % of duplicates did the keys catch? + - What edge cases broke the matching logic? + - Did it hold? Where did it break? What surprised us? + + +### Current Assessment + +**Architecture:** Ready for integration - the design is sound and the implementation is clean. + +**Deduplication accuracy:** Needs real-world validation before production use. The 100% success rate on synthetic data validates the mechanism works, but doesn't yet prove it handles the messy reality of production code reviews. + +**Recommendation:** Run real data validation to measure actual dedup rates and identify edge cases before committing to SQLite cache as the production solution. \ No newline at end of file diff --git a/review-cache-experiment/scripts/extract_functions.sh b/review-cache-experiment/scripts/extract_functions.sh new file mode 100755 index 0000000..2a6a3ee --- /dev/null +++ b/review-cache-experiment/scripts/extract_functions.sh @@ -0,0 +1,94 @@ +#!/bin/bash +# +# Extract function names and code snippets from git files. +# +# Used by save.py to enrich findings before storing. + +set -euo pipefail + +# Extract function name at a given line +extract_function_name() { + local file=$1 + local line=$2 + + # Get file content from git + local content + content=$(git show "HEAD:$file" 2>/dev/null || echo "") + + if [ -z "$content" ]; then + echo "package" + return + fi + + # Search backwards from line for function definition + # Supports Go, Python, JavaScript, Rust + local function_name + function_name=$(echo "$content" | head -n "$line" | tac | \ + grep -m1 -E "^(func |def |function |class |fn |pub fn |impl )" | \ + sed -E 's/^(func |def |function |class |fn |pub fn |impl )([^({\s<]+).*/\2/' || echo "package") + + echo "$function_name" +} + +# Extract code snippet (3 lines of context) +extract_code_snippet() { + local file=$1 + local line=$2 + + # Get file content from git + local content + content=$(git show "HEAD:$file" 2>/dev/null || echo "") + + if [ -z "$content" ]; then + echo "" + return + fi + + # Get line-1, line, line+1 + local start=$((line -
