Session Risk State Tracking Prompt Template

This prompt is for abuse detection engineers and safety platform builders who need to maintain a cumulative risk assessment across a multi-turn conversation, not just evaluate each user message in isolation. The job-to-be-done is tracking whether a user's sequence of requests—even if individually benign—forms a probing pattern that should trigger escalation, stricter refusal, or session termination. The ideal user is someone integrating this prompt into a stateless architecture where each turn must carry forward a serialized risk state because the model or API does not retain memory between calls.

Use this prompt when your safety architecture requires a structured, auditable risk score that accumulates across turns. It is appropriate for conversational agents, customer-facing chatbots, and internal tooling where users might attempt to circumvent policies through gradual boundary testing, rephrasing previously refused requests, or context manipulation. The prompt expects a serialized risk state as input and produces an updated risk state as output, making it suitable for systems that store state externally (e.g., in a session database, Redis, or a key-value store) and inject it into each model call.

Do not use this prompt for single-turn classification or for systems where each user message is evaluated independently with no memory of prior refusals. It is also not a replacement for dedicated jailbreak detection classifiers or real-time injection defenses—those should operate upstream or in parallel. This prompt assumes you already have per-turn safety classifications or refusal decisions to feed into the state tracker. If your system lacks those inputs, you need to build that detection layer first. For high-risk domains such as healthcare, legal, or finance, the risk state output should feed into a human review queue rather than triggering automated enforcement actions without oversight.

Before deploying, define your risk score thresholds, escalation actions, and state schema. The prompt works best when paired with eval harnesses that test multi-turn probing sequences—such as gradual rephrasing attacks, role-play framing across turns, and context-stripping attempts—to verify that the cumulative score rises appropriately and triggers the correct escalation. If your application runs in a regulated environment, ensure that every state transition is logged for auditability and that human reviewers can inspect the full risk trajectory, not just the final score.

This template is designed to be injected at the start of each turn in a multi-turn conversation. It receives the current user input, the serialized session risk state from previous turns, and the organization's safety policy. Its job is to evaluate the cumulative risk, update the state, and determine whether the current request should be refused, escalated, or allowed. The prompt is structured for stateless architectures where the application layer must pass the serialized state in and out on every call.

You are a session safety monitor. Your task is to evaluate the current user request in the context of the full conversation session and update the session risk state.

## SAFETY POLICY
[SAFETY_POLICY]

## CURRENT SESSION RISK STATE
[SESSION_RISK_STATE]

## CURRENT USER REQUEST
[USER_INPUT]

## INSTRUCTIONS
1. Analyze the current request against the SAFETY POLICY. Classify it as ALLOWED, REFUSED, or ESCALATE.
2. Evaluate whether the current request, combined with the prior SESSION_RISK_STATE, indicates a probing pattern, rephrasing attack, or cumulative policy violation.
3. Update the `cumulative_risk_score` (0.0 to 1.0) based on:
   - Severity of the current request.
   - Repetition of previously refused topics.
   - Attempts to rephrase or circumvent prior refusals.
   - Escalation in the danger of requested content.
4. If `cumulative_risk_score` exceeds [ESCALATION_THRESHOLD], set the decision to ESCALATE.
5. Output ONLY the updated session risk state as a valid JSON object matching the [OUTPUT_SCHEMA]. Do not include any other text.

## OUTPUT SCHEMA
{
  "turn_id": "string (increment from prior state)",
  "decision": "ALLOWED | REFUSED | ESCALATE",
  "cumulative_risk_score": "float (0.0 to 1.0)",
  "policy_citation": "string (specific policy clause invoked)",
  "probing_pattern_detected": "boolean",
  "refusal_reason": "string (concise explanation if REFUSED or ESCALATE, otherwise null)",
  "prior_refusals_summary": ["string (list of previously refused request topics)"],
  "escalation_reason": "string (if ESCALATE, otherwise null)"
}

To adapt this template, replace [SAFETY_POLICY] with your organization's concrete policy text—avoid vague language like 'be safe.' The [SESSION_RISK_STATE] placeholder must be populated with the JSON output from the previous turn; on the first turn, pass an initial state with cumulative_risk_score: 0.0 and an empty prior_refusals_summary. Set [ESCALATION_THRESHOLD] to a value that triggers human review before the model is allowed to generate a harmful response—0.7 is a common starting point, but calibrate based on your risk tolerance. The [OUTPUT_SCHEMA] is the contract your application parser expects; validate it strictly after every model response and retry with a repair prompt if the JSON is malformed or missing required fields.

The Session Risk State Tracking prompt is designed for architectures where the model itself is stateless but the application must maintain a cumulative risk assessment across conversation turns. The core implementation pattern is a read-modify-write cycle: before each model call, the application retrieves the serialized risk state from the previous turn, injects it into the prompt's [PRIOR_RISK_STATE] placeholder alongside the current [USER_MESSAGE] and [TURN_HISTORY_SUMMARY], then parses the model's structured output to extract the updated risk state for storage. This state object—typically a JSON blob containing risk_score, probing_patterns_detected, escalation_level, and policy_violations—must be persisted in your session store (Redis, DynamoDB, or similar) with the same TTL as the conversation session.

Validation and retry logic is critical because a malformed risk state update can corrupt the entire session's safety tracking. After each model response, validate that the output contains a parseable [UPDATED_RISK_STATE] with all required fields present and within expected ranges (e.g., risk_score between 0.0 and 1.0, escalation_level as an integer). If validation fails, retry the prompt once with an explicit repair instruction appended to the system message: Your previous output was missing a valid UPDATED_RISK_STATE. Return ONLY the corrected JSON risk state. If the retry also fails, log the failure, freeze the session's risk score at its last known value, and flag the conversation for human review. Do not silently continue with a default or zeroed risk state—this creates a safety gap that adversarial users can exploit by triggering parse failures.

Escalation actions should be implemented in the application layer, not in the prompt. When the returned escalation_level reaches your configured threshold (e.g., level 3 or above), the application should execute pre-defined actions: inject a stricter refusal system prompt for subsequent turns, route the session to a human moderator queue, or terminate the session entirely. Keep escalation thresholds configurable per deployment environment—staging may use lower thresholds for testing, while production uses calibrated values based on your observed false-positive rates. Log every state transition with the full prompt input, model output, and validation result for auditability. When using this prompt with models that support structured output modes (e.g., GPT-4 with JSON mode, Claude with tool use), prefer constrained generation over free-text parsing to reduce validation failures and improve state consistency across turns.
