# DevTools: Code AI — Global Fix Map
# DevTools · Code AI — Global Fix Map
A small hub to stabilize IDE code assistants without touching your infra. Use this to jump to the right per-tool page, then verify fixes with measurable targets.

A hub to stabilize IDE copilots and code-AI assistants without changing infra.
Use this to jump to per-tool guardrails and verify fixes with the same acceptance targets.
## When to use this folder
* IDE plugins misalign during RAG integration: results show high similarity but the semantics are wrong.
* JSON tools return inconsistently: objects fluctuate between valid and broken.
* Multi-step generation runs too long, and answers flip across different executions.
* Local fragments are correctly selected, but citations dont match the actual paragraphs.
* After multiple agents hand over tasks, memory namespaces conflict or overwrite each other.

- IDE chat answers flip between runs or tabs.
- Tool calls loop or stall after partial edits.
- JSON blocks fail or come back as prose.
- RAG answers look right by similarity yet cite the wrong place.
- Long refactors drift after 2040 reasoning steps.
## Acceptance targets
- ΔS(question, retrieved) ≤ 0.45
- Coverage of target section ≥ 0.70
- λ stays convergent across 3 paraphrases and 2 seeds
- E_resonance flat on long windows
- ΔS(question, retrieved) ≤ 0.45
- Coverage ≥ 0.70 to the target section
- λ remains convergent across 3 paraphrases and 2 seeds
- E_resonance stays flat on long windows
## 60-second fix checklist
1) **Measure ΔS**
Compute ΔS(question, retrieved) and ΔS(retrieved, expected anchor). Stable < 0.40, transitional 0.400.60, risk 0.60.
2) **Probe λ_observe**
Vary top-k and prompt headers. If λ flips, lock the schema and clamp with BBAM.
3) **Apply the module**
- Retrieval drift → BBMC + [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)
- Reasoning collapse → BBCR bridge + BBAM
- Dead ends in long runs → BBPF alternate paths
4) **Verify**
Coverage ≥ 0.70 on three paraphrases. λ convergent on two seeds.

## Copy-paste prompt for IDE chat
```
I uploaded TXT OS and WFGY Problem Map.
My IDE assistant issue:
I loaded TXT OS and the WFGY Problem Map.
* symptom: \[brief]
* traces: ΔS(question,retrieved)=..., ΔS(retrieved,anchor)=..., λ across 3 paraphrases
My code-AI issue:
* symptom: \[one line]
* traces: ΔS(question,retrieved)=..., ΔS(retrieved,anchor)=..., λ states across 3 paraphrases
Tell me:
1. failing layer and why,
2. which WFGY page to open,
2. the exact WFGY page to open from this repo,
3. minimal steps to push ΔS ≤ 0.45 and keep λ convergent,
4. a reproducible test to verify.
Use BBMC, BBPF, BBCR, BBAM when relevant.
4. how to verify with a reproducible test.
Use BBMC/BBPF/BBCR/BBAM where relevant.
