Use this when your pipeline uses **Semantic Kernel** planners, function tools, memories, or skills and you see wrong snippets, plan drift, tool loops, or JSON shape errors. The checks below localize the fault, then route to the exact WFGY fix page.

## Core acceptance
- ΔS(question, retrieved) ≤ 0.45
- Coverage ≥ 0.70 for the intended section
- λ remains convergent across three paraphrases and two seeds

---

## Fix in 60 seconds

1) **Measure ΔS**  
Compute ΔS(question, retrieved) and ΔS(retrieved, anchor). Stable < 0.40, transitional 0.40–0.60, risk ≥ 0.60.

2) **Clamp the planner**  
Freeze the planner schema. Require task → constraints → tools → cite then explain. If plan text changes order between runs, lock headers and set deterministic seeds.

3) **Apply the module**  
- Retrieval drift → BBMC with [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)  
- JSON tool variance → tighten schemas and apply [Prompt Injection](https://github.com/onestardao/WFGY/blob/main/ProblemMap/prompt-injection.md) fences  
- Long plans degrade → insert BBCR bridges and cap step depth per segment

4) **Verify**  
Three paraphrases reach ΔS ≤ 0.45 and coverage ≥ 0.70. λ stays convergent.

## Typical Semantic Kernel breakpoints → exact fixes

- **Planner invents tools or repeats steps**  
  Lock tool registry. Enforce idempotent effects with keys.  
  Open: [Multi-Agent Problems](https://github.com/onestardao/WFGY/blob/main/ProblemMap/Multi-Agent_Problems.md), [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)

- **Memory recalls stale facts after refresh**  
  Split namespaces and stamp `mem_rev`, `mem_hash`.  
  Open: [patterns: memory desync](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_memory_desync.md)

- **High similarity yet wrong meaning**  
  Metric or analyzer mismatch across write and read paths.  
  Open: [Embedding ≠ Semantic](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md)

- **Hybrid retrievers worse than single**  
  Query parsing split and misweighted rerank.  
  Open: [Query Parsing Split](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_query_parsing_split.md), [Rerankers](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md)

- **Tool call JSON fails silently**  
  Require strict argument schema. Echo schema at each call.  
  Open: [Prompt Injection](https://github.com/onestardao/WFGY/blob/main/ProblemMap/prompt-injection.md)

## Minimal SK pattern with WFGY gates

```txt
Planner:
  1) Task
  2) Constraints: cite-first, snippet schema, tool JSON strict
  3) Tools with idempotency keys
  4) Answer: cite then explain

Runtime:
  - Retrieve(k = 10 with unified analyzer)
  - Assemble(prompt with headers in fixed order)
  - Reason(model call)
  - WFGY gate: compute ΔS, record λ, verify coverage
  - If ΔS ≥ 0.60 or λ divergent, stop and return fix tip
````

**What this enforces**

* Deterministic header order across steps
* Observable retrieval with stable metric
* Schema locked citations
* A stop gate when structure collapses

---

## SK specific gotchas

* Planner temperature is non zero while tools expect strict JSON. Set low variance and validate before acting.
* Memories are written by multiple skills without namespace fences. Use separate namespaces and revision stamps.
* Rerun of the same plan writes duplicate side effects. Add idempotency keys before external actions.

---

## When to escalate

* ΔS stays ≥ 0.60 after chunk and retrieval fixes
  Rebuild index and recheck analyzers.
  Open: [Retrieval Playbook](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-playbook.md)

* Answers flip between sessions with unchanged inputs
  Check version skew and deploy order.
