SDK Reference
Complete configuration reference for the LaunchPromptly Node.js and Python SDKs.
Quick Start#
Install the SDK, wrap your LLM client, and you're done. Every API call runs through the safety pipeline automatically.
pip install launchpromptly openai
# 1. Create instance
from launchpromptly import LaunchPromptly, WrapOptions, SecurityOptions
from launchpromptly import PIISecurityOptions, InjectionSecurityOptions
from openai import OpenAI
lp = LaunchPromptly(api_key="lp_your_key_here")
# 2. Wrap your client — every call now runs through the safety pipeline
openai = lp.wrap(OpenAI(), WrapOptions(
security=SecurityOptions(
pii=PIISecurityOptions(enabled=True, redact=True),
injection=InjectionSecurityOptions(enabled=True, block_on_detection=True),
),
))
# 3. Use as normal — PII is redacted, injections are blocked automatically
response = openai.chat.completions.create(
model="gpt-4o",
messages=[{"role": "user", "content": "My email is alice@corp.com, summarize the report"}],
)
print(response.choices[0].message.content)
# Input PII (alice@corp.com) was redacted before reaching OpenAI
# Dashboard shows the event with guardrail resultsWhat just happened?
The SDK intercepted the OpenAI call, redacted the email address before it reached the API, scanned the prompt for injection attacks, and logged the event to your dashboard. Your LLM never saw the raw PII.
Installation#
pip install launchpromptlyEnvironment Variables
The SDK automatically looks for an API key in this order: apiKey constructor option, then LAUNCHPROMPTLY_API_KEY, then LP_API_KEY. Get your key from Sign up to get your API key.
Constructor Options#
Create a LaunchPromptly instance with these options. Most have sensible defaults so you only need to provide your API key to get started.
| Option | Type | Default | Description |
|---|---|---|---|
| api_key | string | env var | Your LaunchPromptly API key. Falls back to LAUNCHPROMPTLY_API_KEY or LP_API_KEY. |
| endpoint | string | LaunchPromptly cloud | API endpoint URL. Only change if self-hosting. |
| flush_at | int | 10 | Number of events to buffer before flushing to the API. |
| flush_interval | float | 5.0 (sec) | Time interval between automatic flushes. |
| on | object | — | Guardrail event handlers. See Events section for all event types. |
from launchpromptly import LaunchPromptly
lp = LaunchPromptly(
api_key=os.environ.get("LAUNCHPROMPTLY_API_KEY"), # or LP_API_KEY
endpoint="https://your-api.example.com", # defaults to LaunchPromptly cloud
flush_at=10, # flush events after 10 in queue
flush_interval=5.0, # or every 5 seconds
on={
"pii.detected": lambda event: print("PII found:", event.data),
"injection.blocked": lambda event: print("Injection blocked!"),
},
)Wrap Options#
Pass these options when wrapping an LLM client. The security option contains all guardrail configuration. Customer and trace context help you track usage per-user in the dashboard.
| Option | Type | Default | Description |
|---|---|---|---|
| customer | Callable | — | Function returning { id, feature? }. Called per-request for cost tracking. |
| feature | string | — | Feature tag (e.g., "chat", "search") for analytics grouping. |
| trace_id | string | — | Request trace ID for distributed tracing. |
| span_name | string | — | Span name for tracing context. |
| security | SecurityOptions | — | Security configuration. Contains pii, injection, costGuard, contentFilter, modelPolicy, streamGuard, outputSchema, audit. |
openai_client = lp.wrap(OpenAI(), WrapOptions(
customer=lambda: CustomerContext(id=get_current_user_id()),
feature="chat",
trace_id=request_id,
span_name="openai-chat",
security=SecurityOptions(
pii=PIISecurityOptions(enabled=True, redaction="placeholder"),
injection=InjectionSecurityOptions(enabled=True, block_on_high_risk=True),
cost_guard=CostGuardOptions(max_cost_per_request=0.50),
),
))
# Use as normal — all guardrails run automatically
response = openai_client.chat.completions.create(
model="gpt-4o",
messages=[{"role": "user", "content": user_input}],
)L1: Input/Output Detection#
L1 is the always-on detection layer. 14+ guardrails scan every input before the LLM call and every output after. Sub-millisecond latency, zero dependencies. Optional ML enhancement for each guardrail.
Security Configuration#
The security option in wrap options accepts fourteen sub-modules. Each can be enabled independently. When multiple are active, they run in the pipeline order shown at the bottom of this page.
PII Detection & Redaction#
Scans input messages for personally identifiable information before they reach the LLM. Detected PII is replaced using your chosen strategy, and the original values are automatically restored in the response (de-redaction).
| Option | Type | Default | Description |
|---|---|---|---|
| enabled | boolean | true | Toggle PII detection on/off. |
| redaction | string | "placeholder" | Strategy: "placeholder" | "synthetic" | "hash" | "mask" | "none" |
| types | string[] | all 16 types | Which PII types to detect. See table below. |
| scan_response | boolean | false | Also scan LLM output for PII leakage. |
| providers | Provider[] | — | Additional ML-based detectors. Results merge with regex. |
| on_detect | callback | — | Called when PII is detected, receives detection array. |

openai_client = lp.wrap(OpenAI(), WrapOptions(
security=SecurityOptions(
pii=PIISecurityOptions(
enabled=True,
redaction="placeholder", # "placeholder" | "synthetic" | "hash" | "mask" | "none"
types=["email", "phone", "ssn", "credit_card"], # default: all 16 types
scan_response=True, # also scan LLM output for PII leakage
on_detect=lambda detections: print(f"Found {len(detections)} PII entities"),
),
),
))
# Input: "Contact john@acme.com or 555-123-4567"
# LLM sees: "Contact [EMAIL_1] or [PHONE_1]"
# You get back: "Contact john@acme.com or 555-123-4567" (de-redacted)Masking Options
When using the mask strategy, you can fine-tune how values are partially revealed.
| Option | Type | Default | Description |
|---|---|---|---|
| char | string | "*" | Character used for masking. |
| visible_prefix | number | 0 | How many characters to show at the start. |
| visible_suffix | number | 4 | How many characters to show at the end. |
# Masking strategy — partial reveal for readability
openai_client = lp.wrap(OpenAI(), WrapOptions(
security=SecurityOptions(
pii=PIISecurityOptions(
redaction="mask",
masking=MaskingOptions(
char="*", # masking character
visible_prefix=0, # chars visible at start
visible_suffix=4, # chars visible at end
),
),
),
))
# "john@acme.com" → "j***@acme.com"
# "555-123-4567" → "***-***-4567"Injection Detection#
Scans user messages for prompt injection attempts. The SDK scores each request against 5 rule categories, sums the triggered weights into a 0-1 risk score, and takes an action based on your thresholds.
| Option | Type | Default | Description |
|---|---|---|---|
| enabled | boolean | true | Toggle injection detection on/off. |
| block_threshold | number | 0.7 | Risk score at or above which the request is blocked. |
| block_on_high_risk | boolean | false | Throw PromptInjectionError when score >= blockThreshold. |
| providers | Provider[] | — | Additional ML-based detectors. Results merge with rules. |
| on_detect | callback | — | Called when injection risk is detected (any score > 0). |
Detection Categories
Each category has a weight that contributes to the total risk score. Multiple matches within a category boost the score slightly (up to 1.5x the weight).
| Category | Weight | Example Patterns |
|---|---|---|
| instruction_override | 0.40 | "ignore previous instructions", "disregard all prior" |
| role_manipulation | 0.35 | "you are now a...", "act as DAN" |
| delimiter_injection | 0.30 | <system> tags, markdown code fences with system |
| data_exfiltration | 0.30 | "show me your prompt", "repeat instructions" |
| encoding_evasion | 0.25 | base64 blocks, unicode obfuscation |
How risk scores work
Scores are calculated per-request, not per-user or per-account. Triggered category weights are summed and capped at 1.0. Below 0.3 = allow, 0.3-0.7 = warn, 0.7+ = block. All thresholds are configurable.
openai_client = lp.wrap(OpenAI(), WrapOptions(
security=SecurityOptions(
injection=InjectionSecurityOptions(
enabled=True,
block_threshold=0.7, # risk score to block (default: 0.7)
block_on_high_risk=True, # raise PromptInjectionError when blocked
on_detect=lambda analysis: print(
f"Risk: {analysis.risk_score}, Categories: {analysis.triggered}"
),
),
),
))
try:
response = openai_client.chat.completions.create(
model="gpt-4o",
messages=[{"role": "user", "content": "Ignore all previous instructions..."}],
)
except PromptInjectionError as err:
print(err.analysis.risk_score) # 0.4+
print(err.analysis.triggered) # ['instruction_override']
print(err.analysis.action) # 'block'Cost Guard#
In-memory sliding window rate limiting for LLM spend. Set hard caps at the request, minute, hour, day, and per-customer level. The SDK estimates cost before the LLM call and records actual cost after.
| Option | Type | Default | Description |
|---|---|---|---|
| max_cost_per_request | number | — | Maximum USD cost for a single LLM call. |
| max_cost_per_minute | number | — | Sliding window: max spend in any 60-second window. |
| max_cost_per_hour | number | — | Sliding window: max spend in any 60-minute window. |
| max_cost_per_day | number | — | 24-hour rolling window: max spend in any 24-hour period. |
| max_cost_per_customer | number | — | Per-customer hourly cap. Requires customer() in wrap options. |
| max_cost_per_customer_per_day | number | — | Per-customer daily cap. Requires customer() in wrap options. |
| max_tokens_per_request | number | — | Hard cap on max_tokens parameter per request. |
| block_on_exceed | boolean | true | Throw CostLimitError when any budget limit is exceeded. |
| on_budget_exceeded | callback | — | Called when a budget limit is hit, receives BudgetViolation. |
In-memory tracking
Cost tracking resets when the SDK restarts. For persistent budget enforcement, combine with server-side policies in the dashboard. Per-customer limits require the customer function in wrap options.
openai_client = lp.wrap(OpenAI(), WrapOptions(
security=SecurityOptions(
cost_guard=CostGuardOptions(
max_cost_per_request=0.50, # single request cap
max_cost_per_minute=2.00, # sliding window
max_cost_per_hour=20.00, # sliding window
max_cost_per_day=100.00, # 24-hour rolling window
max_cost_per_customer=5.00, # per-customer hourly cap
max_cost_per_customer_per_day=25.00, # per-customer daily cap
max_tokens_per_request=4096, # token limit per request
block_on_exceed=True, # raise CostLimitError (default: True)
on_budget_exceeded=lambda v: print(f"Budget hit: {v.type}, spent: ${v.current_spend}"),
),
),
customer=lambda: CustomerContext(id=user_id), # required for per-customer limits
))Content Filter#
Detects harmful, toxic, or policy-violating content in both inputs and outputs. Includes 5 built-in categories plus support for custom regex patterns.

CustomPattern(name="competitor_mention", pattern=re.compile(r"CompetitorName", re.I), severity="warn"),
CustomPattern(name="internal_project", pattern=re.compile(r"Project\s+Codename", re.I), severity="block"),
],
),
),
))Model Policy#
Pre-call guard that validates LLM request parameters against a configurable policy. Runs first in the pipeline, before any other security checks.

| max_tokens_exceeded | max_tokens parameter exceeds the policy maxTokens |
| temperature_exceeded | temperature parameter exceeds the policy maxTemperature |
| system_prompt_blocked | Request includes a system message and blockSystemPromptOverride is true |
openai_client = lp.wrap(OpenAI(), WrapOptions(
security=SecurityOptions(
model_policy=ModelPolicyOptions(
allowed_models=["gpt-4o", "gpt-4o-mini"], # whitelist
max_tokens=4096, # cap max_tokens parameter
max_temperature=1.0, # cap temperature
block_system_prompt_override=True, # reject user-supplied system messages
on_violation=lambda v: print(f"Policy violation: {v.rule} — {v.message}"),
),
),
))
# This would raise ModelPolicyError:
openai_client.chat.completions.create(
model="gpt-3.5-turbo", # not in allowed_models
messages=[{"role": "user", "content": "Hello"}],
)Output Schema Validation#
Validates LLM JSON output against a JSON Schema (Draft-07 subset). Useful for structured output workflows where you need guaranteed response formats.
| Option | Type | Default | Description |
|---|---|---|---|
| schema | JsonSchema | — | The JSON schema to validate against. See supported keywords below. |
| block_on_invalid | boolean | false | Throw OutputSchemaError if validation fails. |
| on_invalid | callback | — | Called when validation fails. Receives array of SchemaValidationError. |
Supported JSON Schema Keywords
typepropertiesrequireditemsenumconstminimummaximumminLengthmaxLengthpatternminItemsmaxItemsadditionalPropertiesoneOfanyOfallOfnotNon-streaming only
Schema validation runs after the full response is received. It does not apply to streaming responses. For streaming, use the Stream Guard instead.
openai_client = lp.wrap(OpenAI(), WrapOptions(
security=SecurityOptions(
output_schema=OutputSchemaOptions(
schema={
"type": "object",
"required": ["name", "score", "tags"],
"properties": {
"name": {"type": "string", "minLength": 1},
"score": {"type": "number", "minimum": 0, "maximum": 100},
"tags": {"type": "array", "items": {"type": "string"}, "minItems": 1},
},
"additionalProperties": False,
},
block_on_invalid=True, # raise OutputSchemaError
on_invalid=lambda errors: [print(f"{e.path}: {e.message}") for e in errors],
),
),
))Stream Guard#
Real-time security scanning for streaming LLM responses. Uses a rolling window approach to scan chunks as they arrive, without waiting for the full response. Can abort the stream mid-flight if a violation is detected.
| Option | Type | Default | Description |
|---|---|---|---|
| pii_scan | boolean | auto | Enable mid-stream PII scanning. Defaults to true when security.pii is configured. |
| injection_scan | boolean | auto | Enable mid-stream injection scanning. Defaults to true when security.injection is configured. |
| scan_interval | number | 500 | Characters between periodic scans. |
| window_overlap | number | 200 | Overlap in characters when the rolling window advances. Prevents missing PII that spans chunk boundaries. |
| on_violation | string | "flag" | "abort" stops the stream. "warn" fires callback. "flag" adds to final report. |
| final_scan | boolean | true | Run a full-text scan after the stream completes. |
| track_tokens | boolean | true | Enable approximate token counting (chars / 4). |
| max_response_length | object | — | Response length limits: { maxChars, maxWords }. Stream aborts if exceeded. |
| on_stream_violation | callback | — | Called per violation during streaming. Receives StreamViolation. |
How rolling window scanning works
The stream guard accumulates text in a buffer. Every scanInterval characters, it scans the latest window. The windowOverlap ensures PII or injection patterns that span chunk boundaries are caught. After the stream ends, a finalScan of the complete response runs.
openai_client = lp.wrap(OpenAI(), WrapOptions(
security=SecurityOptions(
pii=PIISecurityOptions(enabled=True, redaction="placeholder"),
injection=InjectionSecurityOptions(enabled=True),
stream_guard=StreamGuardOptions(
pii_scan=True, # scan chunks for PII mid-stream
injection_scan=True, # scan chunks for injection mid-stream
scan_interval=500, # chars between scans (default: 500)
window_overlap=200, # rolling window overlap (default: 200)
on_violation="abort", # "abort" | "warn" | "flag" (default: "flag")

# Stream is scanned in real-time — aborts if PII or injection detectedJailbreak Detection#
Detects known jailbreak templates (DAN, STAN, DUDE, etc.), persona assignment attacks, and hypothetical framing techniques. Uses a weighted scoring algorithm that combines pattern matches across multiple categories into a single 0-1 risk score.
| Option | Type | Default | Description |
|---|---|---|---|
| enabled | boolean | true | Toggle jailbreak detection on/off. |
| block_threshold | number | 0.7 | Risk score at or above which the request is blocked. |
| warn_threshold | number | 0.3 | Risk score at or above which a warning is issued. |
| block_on_detection | boolean | false | Throw JailbreakError when score >= blockThreshold. |
| on_detect | callback | — | Called when jailbreak patterns are detected. Receives analysis object. |
Detection Categories
| Category | Weight | Example Patterns |
|---|---|---|
| known_template | 0.45 | "DAN mode", "STAN", "DUDE", "AIM", "Developer Mode" |
| persona_assignment | 0.35 | "you are now an unrestricted AI", "pretend you have no limits" |
| hypothetical_framing | 0.30 | "in a fictional world where", "imagine you could", "for educational purposes" |
| constraint_removal | 0.35 | "ignore your safety guidelines", "bypass your filters", "disable content policy" |

except JailbreakError as err:
print(err.analysis.risk_score) # 0.85
print(err.analysis.type) # 'known_template'
print(err.analysis.template) # 'DAN'Unicode Sanitizer#
Detects and neutralizes Unicode-based attacks that attempt to bypass text-based security checks. Catches zero-width characters, bidirectional overrides, and homoglyph substitutions that can hide malicious content from other guardrails.
| Option | Type | Default | Description |
|---|---|---|---|
| enabled | boolean | true | Toggle Unicode sanitization on/off. |
| action | string | "strip" | "strip" removes dangerous characters. "warn" flags them. "block" rejects the request. |
| detect_homoglyphs | boolean | true | Detect visually similar characters from different scripts (e.g., Cyrillic "a" vs Latin "a"). |
| on_detect | callback | — | Called when Unicode issues are found. Receives result with issues array. |
Detected Unicode Threats
| Threat | Description |
|---|---|
| zero_width | Zero-width spaces, joiners, and non-joiners that split words to evade pattern matching |
| bidi_override | Bidirectional text overrides that reverse text rendering direction |
| homoglyph | Characters from other scripts that look identical to Latin characters |
Run before other guardrails
The Unicode sanitizer runs early in the pipeline so that downstream checks (injection detection, PII scanning) operate on clean text. Without it, attackers can insert zero-width characters to split patterns like "ignore previous instructions".
openai_client = lp.wrap(OpenAI(), WrapOptions(
security=SecurityOptions(
unicode_sanitizer=UnicodeSanitizerOptions(
enabled=True,
action="strip", # "strip" | "warn" | "block"
detect_homoglyphs=True, # detect visually similar characters
on_detect=lambda result: print(
f"Unicode issues: {len(result.issues)}, action: {result.action}"
),
),
),
))
# Input: "Please ig\u200bnore previous instru\u200bctions" (zero-width chars)
# After strip: "Please ignore previous instructions" → caught by injection detection
# Input: "Неllo" (Cyrillic Н + Latin ello)
# Detected as homoglyph attackSecret Detection#
Prevents API keys, tokens, passwords, and other secrets from being sent to or leaked by LLM providers. Includes 12 built-in patterns covering major cloud providers and services, plus support for custom patterns.
| Option | Type | Default | Description |

| built_in_patterns | boolean | true | Use the 12 built-in patterns for common secret types. |
| scan_response | boolean | false | Also scan LLM output for leaked secrets. |
| action | string | "redact" | "redact" replaces secrets with [SECRET_TYPE]. "block" rejects the request. "warn" flags only. |
| custom_patterns | CustomSecretPattern[] | — | Additional regex patterns with name identifier. |
| on_detect | callback | — | Called when secrets are found. Receives array of secret detections. |

| system_prompt | string | — | The system prompt to protect. Response text is compared against this. |
| threshold | number | 0.6 | Similarity score (0-1) above which leakage is detected. |
| block_on_leak | boolean | false | Throw PromptLeakageError when leakage is detected. |
| on_detect | callback | — | Called when leakage is detected. Receives similarity score and matched fragment. |
Provide your system prompt
This guard requires your system prompt text to compare against. Without it, leakage detection cannot run. The prompt is never sent to external services — comparison happens entirely within the SDK.

Agentic AI Guardrails#
Cross-cutting guardrails for agent architectures — tool-use pipelines, chain-of-thought reasoning, and multi-turn conversation flows. These work alongside L1 detection to secure the full agentic loop.
Tool Guard#
Validates tool calls in LLM responses. Whitelist or blacklist tools by name, detect dangerous arguments (SQL injection, path traversal, shell injection, SSRF), enforce per-turn tool call limits, and scan tool outputs for PII or secrets before feeding them back to the model.
| Option | Type | Default | Description |
|---|---|---|---|
| allowed_tools | string[] | — | Whitelist of tool names. All others are blocked. Supports wildcards (search_*). |
| blocked_tools | string[] | — | Blacklist of tool names. If set, only these are blocked. |
| dangerous_arg_detection | boolean | true | Detect SQL injection, path traversal, shell injection, and SSRF in tool arguments. |
| max_tool_calls_per_turn | number | — | Max tool calls allowed in a single LLM response. |
| scan_tool_results | boolean | false | Run PII/injection/secret detection on tool outputs. |
| action | string | "block" | "block" throws ToolGuardError. "warn" returns violations. "flag" logs only. |
Built-in Dangerous Argument Patterns
| Category | Examples |
|---|---|
| SQL injection | UNION SELECT, DROP TABLE, OR 1=1 |
| Path traversal | ../../etc/passwd, %2e%2e%2f |
| Shell injection | $(curl ...), `rm -rf /`, ; cat /etc/shadow |

Scans reasoning and thinking blocks from model outputs. Detects injection attempts hidden in chain-of-thought, system prompt leakage in reasoning, and goal drift where the model's reasoning diverges from the original task.
| Option | Type | Default | Description |
|---|---|---|---|
| injection_detection | boolean | true | Run injection detection on extracted reasoning text. |
| system_prompt_leak_detection | boolean | true | Detect system prompt text repeated in reasoning (n-gram similarity). |
| goal_drift_detection | boolean | false | Detect reasoning about unrelated topics (Jaccard keyword overlap). |
| goal_drift_threshold | number | 0.3 | Similarity threshold for goal drift. Lower = stricter. |
| task_description | string | — | Original task description for drift comparison. Falls back to first user message. |
| action | string | "warn" | "block" throws ChainOfThoughtError. "warn" returns violations. "flag" logs only. |

Stateful guard that tracks context across multiple LLM calls within a conversation. Unlike other guards, this is a class you instantiate once per conversation and pass to wrap().
| Option | Type | Default | Description |
|---|---|---|---|
| max_turns | number | — | Hard limit on conversation depth. Blocks after this many turns. |
| accumulating_risk | boolean | false | Sum injection/jailbreak risk scores across turns. |

Attach request context (trace IDs, customer IDs, feature names) that propagates through async operations. This context is included in events sent to the dashboard, making it easy to correlate LLM calls with your application's request lifecycle.
| Option | Type | Default | Description |
|---|---|---|---|
| trace_id | string | — | Unique request identifier for distributed tracing. |
| span_name | string | — | Name of the current span / operation. |
| customer_id | string | — | End-user identifier for per-customer analytics. |
| feature | string | — | Feature or module name (e.g., "chat", "search"). |
| metadata | Record<string, string> | — | Arbitrary key-value pairs attached to events. |

| Option | Type | Default | Description |
|---|---|---|---|
| LaunchPromptly.init(**kwargs) | — | — | Create and return the singleton instance. |
| LaunchPromptly.shared() | — | — | Access the singleton. Throws if init() has not been called. |

passML-Enhanced Detection#
Optional ML models that run locally alongside the built-in regex engine. Both detection layers merge their results, giving you higher accuracy without sacrificing the speed of regex-based detection.
ML across all layers
L1 Regex (always on): Zero dependencies, microseconds, catches obvious patterns.
L1 ML (opt-in): Local ONNX models — DeBERTa injection, Toxic-BERT content, NER PII. No cloud calls, <100ms.
L3 ML (opt-in): Embedding-based zero-shot classification for context extraction from complex system prompts.
L4 ML (opt-in): NLI cross-encoder for semantic compliance checking — determines whether responses entail or contradict constraints.
| Detector | Model | Plugs Into |
|---|---|---|
| MLToxicityDetector | Xenova/toxic-bert | contentFilter.providers |
| MLInjectionDetector | protectai/deberta-v3 | injection.providers |

# L1 regex + L1 ML results are merged for higher accuracyLifecycle Methods#
Manage event flushing and cleanup. Always call shutdown() or flush() before your process exits to avoid losing pending events.
| Method | Description |
|---|---|
| flush() | Send all pending events to the API. Returns a promise. |
| destroy() | Stop timers and discard pending events. Synchronous. |
| shutdown() | Flush pending events, then destroy. Graceful shutdown. |
| is_destroyed | Boolean property. True after destroy() or shutdown() is called. |
# Flush pending events (e.g., before serverless function returns)
await lp.flush()
# Graceful shutdown — flushes then destroys
await lp.shutdown()
# Immediate cleanup — stops timers, discards pending events
lp.destroy()
# Check if instance has been destroyed
if lp.is_destroyed:
# create a new instance

signal.signal(signal.SIGTERM, handle_sigterm)Security Pipeline Order#
When you call openai.chat.completions.create() through a wrapped client, these steps run in order. Each step can block the request or modify the data before passing it to the next.
Model Policy Check
Block disallowed models, enforce token/temperature limits
Cost Guard Pre-Check
Estimate cost and check against all budget limits
PII Detection (input)
Scan messages for emails, SSNs, credit cards, etc.
PII Redaction (input)
Replace PII with placeholders, synthetic data, or hashes
Injection Detection
Score input for prompt injection risk, block if above threshold
Content Filter (input)
Check for hate speech, violence, and custom patterns
LLM API Call
Forward the (possibly modified) request to the LLM provider
Content Filter (output)
Scan the LLM response for policy violations
Schema Validation
Validate JSON output against your schema
PII Detection (output)
Scan response for PII leakage if scanResponse is enabled
De-redaction
Restore original values in the response (placeholder/synthetic/hash)
Cost Guard Record
Record actual cost from usage data
Event Batching
Queue event for dashboard reporting
Streaming
For streaming calls, steps 7-10 are handled by the Stream Guard engine, which scans chunks in real-time using a rolling window. The final scan after the stream completes covers the full response text.
L2: Red Team Engine#
L2 is the proactive security testing layer. Run 80+ built-in attack payloads against your configured guardrails to find vulnerabilities before production. Produces a scored vulnerability report with OWASP LLM Top 10 mapping.

All guardrail categories the SDK can detect. Regex-based rules ship by default. Categories marked (ML) have optional ML-enhanced detection for better accuracy.
Content Filter
| Category | Severity | Example |
|---|---|---|

L3: Context Engine#
L3 parses your system prompt once and extracts a structured ContextProfile — role, allowed topics, constraints, and behavioral boundaries. This profile is cached (invalidated on prompt change via hash comparison) and fed to L4 for boundary enforcement.
Context Extraction#
lp = LaunchPromptly(
api_key="lp_...",
context_engine={"enabled": True},
)
# Context is extracted automatically when wrap() is called
# with a system prompt. You can also extract manually:
profile = lp.extract_context(
"You are a financial advisor. Only discuss investments. Never give tax advice."
)
print(profile.role) # "financial advisor"
print(profile.topics) # ["investments"]
print(profile.constraints) # ["Never give tax advice"]ContextProfile Fields
| Option | Type | Default | Description |
|---|---|---|---|
| role | string | — | The role or persona extracted from the system prompt (e.g., "customer support agent"). |
| topics | string[] | [] | Allowed topics or domains the model should discuss. |
| constraints | string[] | [] | Explicit restrictions (e.g., "Never discuss competitors"). |
| boundaries | string[] | [] | Behavioral boundaries (e.g., "Always recommend consulting a professional"). |
| tone | string | — | Expected tone or style (e.g., "professional", "friendly"). |
| outputFormat | string | — | Expected output format if specified (e.g., "JSON", "markdown"). |
| hash | string | — | SHA-256 hash of the system prompt. Used for cache invalidation. |
ML-Enhanced Extraction
By default, context extraction uses rule-based parsing. For better accuracy with complex system prompts, enable the ML Context Extractor — it uses embedding-based zero-shot classification to identify roles, topics, and constraints that regex patterns miss.
L4: Response Judge#
L4 checks every LLM response against the boundaries extracted by L3. If the model goes off-topic, violates a constraint, or drifts from its assigned role, the Response Judge catches it and can block, warn, or flag.
Response Judge#
lp = LaunchPromptly(
api_key="lp_...",
context_engine={"enabled": True},
response_judge={
"enabled": True,
"block_on_violation": True,
"scoring_weights": {
"topic_drift": 0.3,
"constraint_violation": 0.4,
"role_drift": 0.2,
"tone_shift": 0.1,
},
},
)
# Response Judge runs automatically after every LLM response.
# Violations are reported via the 'response.violation' event:
@lp.on("response.violation")
def handle_violation(violation):
print(violation.type) # "constraint_violation"
print(violation.score) # 0.85
print(violation.detail) # "Response contains tax advice"Violation Types
| Type | Description | Example |
|---|---|---|
| topic_drift | Response discusses topics outside the allowed list | Financial advisor discussing cooking recipes |
| constraint_violation | Response directly violates a stated constraint | "Never give tax advice" but response includes tax guidance |
| role_drift | Response breaks character or adopts a different persona | Support agent starts acting as a developer |
| tone_shift | Response tone doesn't match the specified style | Professional agent using casual slang |
| boundary_breach | Response crosses a behavioral boundary | Agent making promises outside its authority |
| format_violation | Response doesn't match the expected output format | Expected JSON but returned free text |
| Option | Type | Default | Description |
|---|---|---|---|
| enabled | boolean | false | Enable L4 Response Judge. |
| block_on_violation | boolean | false | Block the response and throw ResponseJudgeError on violation. |
| scoring_weights | object | — | Custom weights for each violation type (0.0-1.0). Higher weight = stricter enforcement. |
| threshold | number | 0.7 | Score threshold above which a violation is triggered (0.0-1.0). |
| action | string | "warn" | "block" throws an error. "warn" returns violations. "flag" logs only. |
NLI Cross-Encoder
For higher accuracy, enable the NLI (Natural Language Inference) cross-encoder model. Instead of keyword matching, it uses semantic understanding to determine whether a response entails, contradicts, or is neutral to each constraint. Enable via the ML plugin system.
Troubleshooting#
SDK events not appearing in the dashboard
Check that your API key is valid and the endpoint URL is correct. Call flush() or shutdown() before your process exits, otherwise buffered events may be lost.
False positives on PII detection
Some technical strings (UUIDs, hex values) can match PII patterns. Use the allowList / allow_list option to exclude known-safe patterns from detection.
Injection detection blocks legitimate prompts
Lower the threshold value (default 0.5) or switch to warn mode instead of block. System prompt awareness is built-in, so prompts containing role instructions are automatically suppressed from triggering injection rules.
ML models slow to load on first request
ML-enhanced detection loads models lazily on first use. This can add 2-5 seconds to the first request. Call await lp.warmup() at app startup to pre-load models before serving traffic.
Streaming responses not being scanned
Enable stream guard in your security config: stream_guard=StreamGuardOptions(enabled=True). Without it, streaming calls pass through without mid-stream scanning.
Content filter not catching bias or stereotypes
Bias detection runs on output by default. Make sure your content filter is enabled and scanning the response side. Bias patterns have warn severity, so they won't block unless you set block_on_violation: true.
Python: ImportError for ML modules
ML features require extra dependencies: pip install launchpromptly[ml]. The base package uses regex-only detection and has zero dependencies.
