Use this page when your orchestration uses **CrewAI** (agents, tasks, tools, crews, planning) and you see tool loops, wrong snippets, role mixing, or answers that flip between runs. The table maps symptoms to exact WFGY fix pages and gives a minimal recipe you can paste.
**Acceptance targets**
- ΔS(question, retrieved) ≤ 0.45
- Coverage ≥ 0.70 to the intended section or record
- λ stays convergent across 3 paraphrases and 2 seeds
- E_resonance stays flat on long windows

## Typical breakpoints and the right fix
- **Agent to agent handoff loops or stalls**
Add BBCR bridge steps, set explicit timeouts, log λ per hop, clamp variance with BBAM.

- **High similarity yet wrong meaning**
Mixed write and read embeddings, metric mismatch, or fragmented stores.

- **Hybrid retrieval performs worse than a single retriever**
Two stage query drifts, mis weighted rerank, inconsistent analyzer.

- **Citations missing or inconsistent across agents**
Require cite then explain and lock snippet fields at the task boundary.

- **Planner injects unsafe tool prompts**
Freeze tool schemas and validate arguments before execution.
Open: [Prompt Injection](https://github.com/onestardao/WFGY/blob/main/ProblemMap/prompt-injection.md)
- **Long runs flatten style and drift logically**
Split tasks, re join with BBCR, measure entropy and stop when it rises.

## Fix in 60 seconds
1) **Measure ΔS**
Compute ΔS(question, retrieved) and ΔS(retrieved, expected anchor).
Stable < 0.40, transitional 0.40 to 0.60, risk ≥ 0.60.
2) **Probe λ_observe**
Do a k sweep in retrieval and reorder prompt headers. If λ flips, lock the schema and clamp with BBAM.
3) **Apply the module**
- Retrieval drift → BBMC plus [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)
- Reasoning collapse → BBCR bridge plus BBAM, verify with [Logic Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/logic-collapse.md)
- Hallucination re entry after correction → [Pattern: Hallucination Re-entry](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_hallucination_reentry.md)
4) **Verify**
Coverage ≥ 0.70. ΔS ≤ 0.45. Three paraphrases and two seeds with λ convergent.

## Minimal CrewAI pattern with WFGY checks
```python
# Pseudocode: highlight the control points only
from crewai import Agent, Task, Crew
def retrieve_snippets(q):
# unified analyzer and metric across dense and sparse
return retriever.search(q, k=10)
def assemble_prompt(context, q):
# schema-locked prompt with cite first
return prompt.format(context=context, question=q)
def wfgy_checks(q, context, answer):
# compute ΔS(question, context) and enforce thresholds
# record snippet_id, section_id, source_url, offsets, tokens
metrics = metrics_and_trace(q, context, answer)
if metrics["risk"]:
raise RuntimeError("WFGY gate: high ΔS or divergent λ")
return metrics
researcher = Agent(
role="retrieval",
goal="fetch auditable snippets with fields locked",
backstory="RAG specialist who always cites first"
)
writer = Agent(
role="reasoning",
goal="answer with cite then explain using the snippet schema",
backstory="keeps λ convergent and avoids cross section reuse"
)
task_retrieve = Task(
description="Retrieve k=10 with unified analyzer, return snippet schema",
agent=researcher,
expected_output="list of snippets with {snippet_id, section_id, source_url, offsets, tokens}"
)
task_answer = Task(
description="Assemble cite-first prompt and answer with strict JSON",
agent=writer,
expected_output="{citations:[...], answer:'...'}"
)
crew = Crew(agents=[researcher, writer], tasks=[task_retrieve, task_answer])
def run(question):
context = retrieve_snippets(question)
msg = assemble_prompt(context, question)
answer = crew.kickoff(inputs={"msg": msg})
metrics = wfgy_checks(question, context, answer)
return {"answer": answer, "metrics": metrics}
````
**What this enforces**
* Retrieval is observable and parameterized. Analyzer and metric are unified.
* Prompt is schema locked with cite first and strict JSON for tool outputs.
* A post generation WFGY gate can halt the run when ΔS is high or λ flips.
* Traces record snippet to citation mapping for audits.

## CrewAI specific gotchas
* Mixed embedding functions across write and read. Rebuild with explicit metric and normalization.
See [Embedding ≠ Semantic](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md)
* Planner emits tool prompts that bypass the schema. Always validate tool arguments and echo the schema every step.
See [Prompt Injection](https://github.com/onestardao/WFGY/blob/main/ProblemMap/prompt-injection.md)
* Memory overwrite between agents. Stamp `mem_rev` and `mem_hash`, split namespaces by agent role.
See [role drift](https://github.com/onestardao/WFGY/blob/main/ProblemMap/multi-agent-chaos/role-drift.md) · [memory desync](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_memory_desync.md)
* Event storms when multiple tasks write to the same index or KV. Add idempotency keys on `{source_id, mem_rev, index_hash}`.
See [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md)
* Long runs degrade style and flip answers. Split the plan, then re join with a BBCR bridge and clamp with BBAM.
See [Context Drift](https://github.com/onestardao/WFGY/blob/main/ProblemMap/context-drift.md)
---
## When to escalate
* ΔS remains ≥ 0.60
Rebuild the index using the checklists and verify with a small gold set.
[Retrieval Playbook](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-playbook.md)
* Identical input yields different answers across runs
Check version skew and session state.
