Use this when your pipeline is built with **deepset Haystack Agents and Tools** and you observe wrong snippets, unstable top k orders, tool loops, or citation gaps. The map below routes symptoms to exact WFGY fixes.
|
||
|
||
## Open these first
|
||
- Visual map and recovery: [RAG Architecture & Recovery](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rag-architecture-and-recovery.md)
|
||
- Retrieval knobs: [Retrieval Playbook](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-playbook.md)
|
||
- Traceability schema: [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md)
|
||
- Schema contracts: [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)
|
||
- Hybrid control: [Rerankers](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md)
|
||
- Chunking and hallucination: [Hallucination](https://github.com/onestardao/WFGY/blob/main/ProblemMap/hallucination.md)
|
||
|
||
## Core acceptance
|
||
- ΔS(question, retrieved) ≤ 0.45
|
||
- Coverage ≥ 0.70 for the intended section
|
||
- λ convergent across three paraphrases
|
||
|
||
---
|
||
|
||
## Fix in 60 seconds
|
||
|
||
1) **Measure ΔS**
|
||
Compare question to retrieved and to the intended anchor.
|
||
|
||
2) **Lock the pipeline**
|
||
Fix the header order. Enforce cite-first. Require strict tool JSON.
|
||
|
||
3) **Apply the module**
|
||
- Retrieval drift → BBMC plus [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)
|
||
- Order instability → add [Rerankers](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md) with explicit metric
|
||
- Hybrid regression → [Query Parsing Split](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_query_parsing_split.md)
|
||
|
||
4) **Verify**
|
||
Three paraphrases pass ΔS and coverage thresholds.
|
||

|
||
|
||
## Typical Haystack breakpoints → exact fixes
|
||
|
||
- **Retriever pipelines mix different analyzers**
|
||
Rebuild with a unified analyzer and metric.
|
||
Open: [Embedding ≠ Semantic](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md)
|
||
|
||
- **Agent loops on tool outputs**
|
||
Add BBCR bridge steps and timeouts.
|
||
Open: [Multi-Agent Problems](https://github.com/onestardao/WFGY/blob/main/ProblemMap/Multi-Agent_Problems.md)
|
||
|
||
- **Citations missing or misaligned**
|
||
Enforce snippet schema and cite then explain.
|
||
Open: [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md), [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)
|
||
|
||
- **Hybrid search underperforms**
|
||
Use deterministic reranking with score normalization.
|
||
Open: [Rerankers](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md)

## Minimal Haystack agent pattern with WFGY gate
|
||
|
||
```txt
|
||
Pipeline:
|
||
- Retriever(k sweep 5, 10, 20 with one analyzer)
|
||
- Prompt with fixed headers: system → task → constraints → citations → answer
|
||
- Model call
|
||
- WFGY gate to compute ΔS and log λ
|
||
- Stop when ΔS ≥ 0.60 or λ divergent and return fix tip
|
||
````
|
||
|
||
---
|
||
|
||
## Gotchas
|
||
|
||
* Mixing BM25 and dense without normalization gives unstable orders.
|
||
* Tool output not validated causes downstream JSON errors.
|
||
* Document stores with heterogeneous tokenization contaminate scores.
|
||
|
||
---
|
||
|
||
## When to escalate
|
||
|
||
* Persistent ΔS ≥ 0.60 after chunk and metric fixes
|
||
Open: [Retrieval Playbook](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-playbook.md)
|
||
|
||
* Live flips between runs
