AWS connect documentation change
Summary
Removed the entire 'Prompt engineering best practices for agentic self-service' section, which contained detailed guidance on structuring prompts, defining success/failure criteria, using directive language, conditional logic, restrictions, avoiding contradictions, and other AI agent optimization techniques.
Security assessment
The change removes general prompt engineering guidance without any indication of addressing a specific security vulnerability or incident. While some removed content mentioned security-related concepts (like 'security breaches' in the context of directive language), this was part of general best practices rather than documentation of a security fix. The removal appears to be a content reorganization or simplification, not a security-related update.

A recommended structure is: - - - ## IDENTITY - Role, expertise, and personality - - ## RESPONSE BEHAVIOR - Communication style, tone, and response length - - ## AGENT EXPECTATIONS - Primary objective, success criteria, and failure conditions - - ## STANDARD PROCEDURES - Pre-action requirements and task workflows - - ## RESTRICTIONS - NEVER / ALWAYS / OUT OF SCOPE rules - - ## ESCALATION BOUNDARIES - Triggers and protocol for human handoff - -LLMs parse structured content with headers and bullets more reliably than unstructured prose. Use this structure as a starting point and adapt it to your domain. - -### Define success and failure criteria - -Explicit success and failure criteria transform a general objective into a concrete evaluation framework. Success criteria pull the AI agent toward target outcomes, while failure conditions push it away from unacceptable states. Keep each list to 3–5 specific, observable items. Success and failure should cover different dimensions, not be inversions of each other. - -#### Bad example - - - ## Success Criteria - - Customers are happy with the service - - The agent is helpful and professional - - ## Failure Conditions - - The agent is not helpful - - The customer gets upset - -These criteria are vague, not observable from a transcript, and the failure conditions are just inversions of the success criteria. - -#### Good example - - - ## Success Criteria - The agent is succeeding when: - - Every policy citation matches current official documentation - - The customer is given a clear, actionable next step before the - conversation ends - - ## Failure Conditions - The agent has failed when: - - The agent fabricates or guesses at a policy, price, or procedure - rather than acknowledging uncertainty - - The customer has to repeat information they already provided - - An action is taken on the customer's account without first - confirming with the customer - -These criteria are specific, verifiable from a transcript, and cover different dimensions of agent behavior. - -### Lead with instructions, reinforce with examples - -State critical rules as clear instructions, then immediately provide a worked example showing the exact expected behavior. Instructions alone may be insufficient — the AI agent needs to see both the rule and a step-by-step demonstration to follow it reliably. - -### Use strong directive language for critical instructions - -AI agents follow instructions more reliably when they use strong directive keywords such as MUST, MUST NOT, and SHOULD. Reserve capitalization for instructions where non-compliance causes real harm — security breaches, financial errors, or privacy violations. If everything is capitalized, nothing is prioritized. - -#### Bad example - - - ALWAYS greet the user WARMLY and THANK them for contacting us. - -Low-stakes behavior — capitalization is wasted on a greeting instruction. - -#### Good example - - - NEVER process a refund without VERIFIED payment status change. - -High-stakes action — capitalization is warranted for financial operations. - -### Use conditional logic - -Structure guidance with clear if/when/then conditions rather than vague instructions. This helps the AI agent understand exactly when to apply each behavior. - -#### Bad example - - - Help customers with pricing questions and give them the right - information. If there are billing issues, make sure they get - the help they need. - -Vague and open to interpretation — the AI agent has no clear trigger or action to follow. - -#### Good example - - - If the customer asks about pricing but doesn't specify a plan: - → Ask which plan they're interested in before providing details - - When a customer mentions "billing error" or "overcharge": - → Escalate immediately to the billing team - -Clear triggers with specific actions for each condition. - -### Define clear restrictions with NEVER/ALWAYS - -Use graduated restrictions to distinguish between hard rules and soft guidelines.

One rule empowering an action while another prohibits it causes unpredictable behavior. - -#### Bad example - - - ## ALWAYS - - Be fully transparent — share all available information with - the user so they can make informed decisions. - - ## NEVER - - Share internal system details, tool names, or backend processes. - -"Share all available information" conflicts with "Never share internal system details." The AI agent may reveal backend information in an attempt to be transparent, or become paralyzed trying to decide what counts as "all available." - -#### Good example - - - ## ALWAYS - - Be transparent about information relevant to the user's request - — account status, policy details, available options, and next steps. - - ## NEVER - - Share internal system details, tool names, or backend processes. - -Transparency is scoped to user-relevant information, with a clear boundary between what to share and what to withhold. - -### Keep prompts concise - -Longer prompts can lead to performance degradation as the AI agent has more instructions to parse and prioritize. Say it once, say it clearly — redundancy confuses the model and dilutes important instructions. - -#### Bad example - - - When someone wants to cancel their account or delete their profile - or close their membership or terminate their subscription, - escalate immediately. - -Redundant phrasing — four ways of saying the same thing dilutes the instruction. - -#### Good example - - - When a customer requests account cancellation, escalate immediately. - -Clear and concise — one instruction, no ambiguity. - -### Calibrate prompt specificity to model capability - -Smaller, faster models perform well when given precise, step-by-step procedures but struggle when asked to reason independently about ambiguous situations. More capable models require less guidance but trade off latency. Calibrate the specificity of your prompts to the model you are using — provide more detailed instructions and worked examples for smaller models. - -### Use tools for calculations and date arithmetic - -LLMs generate tokens probabilistically rather than computing deterministically, which makes them unreliable for multi-step arithmetic and date comparisons. Any workflow requiring precise calculations — date comparisons, cost totals, unit conversions — should be implemented as an MCP tool call rather than a prompt instruction. - -### Put static domain facts in the prompt - -Domain policies that are constant across all conversations and critical to AI agent behavior should be embedded directly in the system prompt rather than retrieved from a knowledge base via a tool call. Retrieving policies via tool calls means they become part of conversation history and can fall out of the model's context window after many turns. Embedding them in the prompt also benefits from prompt caching, which can reduce latency and cost.
