Semantic Kernel — Guardrails and Fix Patterns

🧭 Quick Return to Map

You are in a sub-page of Agents & Orchestration.
To reorient, go back here:

WFGY Global Fix Map — main Emergency Room, 300+ structured fixes

WFGY Problem Map 1.0 — 16 reproducible failure modes

Think of this page as a desk within a ward.
If you need the full triage and all prescriptions, return to the Emergency Room lobby.

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.

Visual map and recovery: RAG Architecture & Recovery
End to end retrieval knobs: Retrieval Playbook
Why this snippet: Retrieval Traceability
Snippet and citation schema: Data Contracts
Hybrid order control: Rerankers
Hallucination and chunk drift: Hallucination
Prompt injection fences: Prompt Injection
Long chain failures: Context Drift, Entropy Collapse
Agent role conflicts: Multi-Agent Problems

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

Measure ΔS
Compute ΔS(question, retrieved) and ΔS(retrieved, anchor). Stable < 0.40, transitional 0.40–0.60, risk ≥ 0.60.
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.
Apply the module

Retrieval drift → BBMC with Data Contracts
JSON tool variance → tighten schemas and apply Prompt Injection fences
Long plans degrade → insert BBCR bridges and cap step depth per segment

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, Data Contracts
Memory recalls stale facts after refresh
Split namespaces and stamp mem_rev, mem_hash.
Open: patterns: memory desync
High similarity yet wrong meaning
Metric or analyzer mismatch across write and read paths.
Open: Embedding ≠ Semantic
Hybrid retrievers worse than single
Query parsing split and misweighted rerank.
Open: Query Parsing Split, Rerankers
Tool call JSON fails silently
Require strict argument schema. Echo schema at each call.
Open: Prompt Injection

Minimal SK pattern with WFGY gates

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
Answers flip between sessions with unchanged inputs Check version skew and deploy order. Open: Pre-Deploy Collapse
