Deployment Mode Instruction Priority Stacking Prompt

This prompt is for AI platform engineers who are building a single assistant that must operate across multiple deployment environments (development, staging, production) and for multiple tenants, each with their own configuration overrides. The core job-to-be-done is resolving conflicts when base system instructions, environment-specific safety policies, tenant-specific compliance rules, and feature flag behaviors collide. Without an explicit priority stacking mechanism, the model will silently resolve these conflicts in unpredictable ways, often defaulting to the most permissive or the most recent instruction, which can cause production safety failures or break core functionality in restricted environments.

Use this prompt when you have a complex instruction hierarchy that includes at least three of the following layers: a global base system prompt, environment-specific overrides, per-tenant configuration injections, feature flag conditional behaviors, and tool authorization policies. The ideal user is an AI architect or senior engineer who already has these instruction fragments and needs a reliable, testable way to assemble them into a single system message. You must provide the prompt with a structured list of instruction sources, each tagged with a priority level and a source identifier. The prompt will then produce a consolidated system instruction block with explicit conflict resolution rules, a priority precedence table, and documentation requirements for any overrides that were applied.

Do not use this prompt for simple, single-environment assistants or when you have only one layer of instructions. In those cases, a standard system prompt template is sufficient and the overhead of priority stacking logic will add unnecessary token cost and complexity. This prompt is also not a substitute for application-layer enforcement; it defines the behavioral contract for the model, but critical safety rules—such as blocking destructive tool calls in staging—must still be enforced in the execution layer. The output of this prompt should be treated as a living artifact that is versioned, tested with eval suites that check for silent policy suppression, and reviewed whenever a new instruction source is added to the stack.

This template is the core instruction set for an assistant that must adapt its behavior based on deployment context. It establishes a strict priority hierarchy: safety policies always win, followed by environment-specific constraints, tenant overrides, feature flags, and finally base instructions. The template uses square-bracket placeholders that your application layer must resolve before sending the prompt to the model. Each placeholder represents a structured configuration object that your deployment harness should inject at runtime.

# SYSTEM INSTRUCTION PRIORITY STACKING

You are an AI assistant operating in a multi-environment, multi-tenant deployment. Your behavior is governed by a strict priority hierarchy. When instructions conflict, resolve them in this exact order:

## PRIORITY 1: IMMUTABLE SAFETY POLICIES
These rules cannot be overridden by any lower-priority instruction, tenant config, feature flag, or user request:
- [SAFETY_POLICIES]

## PRIORITY 2: ENVIRONMENT-SPECIFIC CONSTRAINTS
Current deployment environment: [DEPLOYMENT_ENVIRONMENT]
Environment-specific rules that apply regardless of tenant or feature flag state:
- [ENVIRONMENT_CONSTRAINTS]

## PRIORITY 3: TENANT-SPECIFIC OVERRIDES
Current tenant: [TENANT_ID]
Tenant-specific policies, terminology, compliance rules, and brand requirements:
- [TENANT_OVERRIDES]

## PRIORITY 4: FEATURE FLAG STATE
Active feature flags for this request:
- [FEATURE_FLAGS]
Capabilities gated by these flags:
- [FLAG_GATED_CAPABILITIES]

## PRIORITY 5: BASE INSTRUCTIONS
Default assistant behavior when no higher-priority rule applies:
- [BASE_INSTRUCTIONS]

## CONFLICT RESOLUTION RULES
1. When a higher-priority rule conflicts with a lower-priority rule, the higher-priority rule wins silently. Do not explain the conflict to the user.
2. When two rules at the same priority level conflict, apply the more restrictive rule.
3. When a user request conflicts with Priority 1 or Priority 2 rules, refuse the request and state which policy prevents fulfillment.
4. When a tenant override conflicts with a safety policy, the safety policy wins. Log the conflict internally but do not expose the override attempt to the user.
5. Feature flags may enable capabilities but cannot disable safety policies or environment constraints.

## OUTPUT REQUIREMENTS
- Before responding, verify your planned response against all five priority levels.
- If any priority level would block or modify your response, adjust accordingly.
- Do not mention priority levels, conflicts, or policy evaluation in your user-facing output unless the user asks about your limitations.
- When refusing a request due to policy, use this format: "I can't [ACTION] because [POLICY_REASON]. [ALTERNATIVE_IF_AVAILABLE]"

## DOCUMENTATION REQUIREMENTS
For every response where a conflict was resolved, append an internal audit block (not visible to the user) with this structure:
[AUDIT: conflict_detected=[TRUE/FALSE], resolved_by=[PRIORITY_LEVEL], override_blocked=[TRUE/FALSE], policy_cited=[POLICY_NAME]]

To adapt this template, replace each square-bracket placeholder with structured content from your configuration system. The [SAFETY_POLICIES] block should contain immutable rules like content restrictions, PII handling requirements, and refusal criteria. The [ENVIRONMENT_CONSTRAINTS] block should gate tool access, logging verbosity, and endpoint restrictions per environment. The [TENANT_OVERRIDES] block should inject tenant-specific compliance rules, terminology maps, and escalation paths. The [FEATURE_FLAGS] block should list active flags and their gated capabilities. The [BASE_INSTRUCTIONS] block should contain the default assistant persona and task instructions. Before deploying, validate that your injection harness resolves all placeholders and that no unresolved tokens reach the model. Test for silent priority inversions by crafting inputs where a lower-priority rule appears to contradict a higher-priority rule and verifying the correct rule wins.

The Deployment Mode Instruction Priority Stacking Prompt is not a standalone artifact; it is a compiler that produces a final system message from multiple conflicting inputs. The implementation harness must call this prompt at assembly time—before the final model request—and treat its output as the authoritative instruction set. The harness is responsible for gathering environment metadata, tenant overrides, feature flag states, and base policies, then injecting them into the prompt's [ENVIRONMENT_POLICIES], [TENANT_OVERRIDES], [FEATURE_FLAGS], and [BASE_INSTRUCTIONS] placeholders. The prompt's output—a structured instruction block with explicit priority rules—becomes the system message for the downstream assistant call. This separation ensures that priority resolution happens deterministically in a single step rather than relying on the assistant model to resolve conflicts at inference time.

To wire this into an application, build a PriorityStackingHarness class or function that accepts a DeploymentContext object. This context must include: environment (dev, staging, prod), tenant_id, active_feature_flags (map of flag name to boolean or variant), and base_policy_version. The harness fetches the corresponding policy documents from a configuration store, assembles the prompt, and calls a fast, instruction-following model (e.g., GPT-4o, Claude 3.5 Sonnet) with temperature=0 and response_format set to a JSON schema that matches the expected output structure. Validate the output before accepting it: check that the priority_stack array is non-empty, that each entry has a rule, source, and priority_level field, and that no two rules have the same priority level. If validation fails, log the raw output, increment a priority_stack_error metric, and fall back to a hardcoded safe default instruction set that blocks all destructive actions. For high-risk deployments, require a human to approve the generated instruction block before it is cached for reuse.

The generated instruction block should be cached per unique combination of environment, tenant, and flag state, with a TTL that matches the shortest-lived input (typically feature flags). Use a distributed cache like Redis with a composite key such as priority_stack:{environment}:{tenant_id}:{flag_hash}. On cache miss, call the harness; on cache hit, retrieve and inject the block into the system message. Log every cache miss and the resulting instruction block hash to an observability platform for auditability. Avoid regenerating the stack on every request—this prompt is an assembly-time operation, not a per-turn operation. The most common production failure is a silent priority inversion where a tenant override unintentionally suppresses a production safety policy. Mitigate this by running a post-generation eval that checks for the presence of critical safety rules (e.g., "never execute destructive tool calls without confirmation") in the final instruction block. If any critical rule is absent, reject the generated stack and alert the on-call channel.
