Agent Platform Alert Configuration

Agent Platform Alert Configuration

Critical Steps

1. Safety & Confirmation Tiers (CRITICAL)

Before executing any commands or writing configurations on behalf of the user,

you MUST adhere to the following safety tiers based on the action requested:

• Tier R: Read-only (check_telemetry.py / gather_agent_info.py)
• Rule: No confirmation needed. You may execute these scripts

immediately to inspect telemetry status or gather agent configuration

details.

• **Tier B: Billing & Resource Creation (create_online_monitor.py /

provisioning)**

• Rule: Explicit User Confirmation Required. These actions incur

additional billing charges and create cloud resources. The agent MUST

ALWAYS warn the user explicitly about the potential extra billing costs

of BOTH the Online Monitor (specifically mentioning LLM evaluations)

and Telemetry (specifically mentioning Cloud Trace/Logging export).

You MUST STOP and ask for explicit approval before proceeding with

provisioning or providing setup commands.

2. Prerequisites & Dependencies

Agent Telemetry

• Disclaimer: For Reliability, Cost, Safety, and Security alerts to

function, the underlying agent MUST be instrumented to emit OpenTelemetry

(OTel) metrics. If the agent does not emit these metrics, the alerting

policies will have no data stream to evaluate.

Python Environment

Before executing any python script in this skill you MUST install the required

dependencies in your environment. Run this command first:

pip install -r scripts/requirements.txt

3. Input Assumptions

• Explicit Project Adherence: You must ONLY configure alerts, query

telemetry, or interact with the Google Cloud Project(s) explicitly provided

by the user in the prompt. Do NOT assume or use other projects from your

environment or history unless the user explicitly directs you to do so.

• Sequential File Transformations: If the user explicitly asks to copy a

file and then modify it, you MUST perform these actions sequentially (copy

first, then modify) rather than writing the final content directly.

4. Execution Steps

• Mandatory Prerequisite Execution Protocol (SEQUENTIAL): Before

generating or writing ANY configuration, you MUST execute these steps in

order:

• Step 1: Streamlined Discovery (Mandatory): Run

gather_agent_info.py to automatically identify agent runtime, check

telemetry, metric scopes, linked datasets, and more. This script covers

most of the manual checks listed in subsequent steps.

• Command: `python3 scripts/gather_agent_info.py --project-id

{project_id} --agent-name {agent_name}`

• Note: If this script fails, returns partial data, or

doesn't produce everything you need, you MUST satisfy requirements

by running the manual fallback steps listed in Step 2 and then

perform Step 3 below. If Step 1 succeeds and provides all info,

SKIP to Step 3 (Pre-existing Policies Check).

• Step 2: Metric Scope Check (Fallback): Run this ONLY if Step 1

failed to determine the metric scope.

• Action A (CLI): Run `gcloud beta monitoring metrics-scopes list

projects/{project_id}`. If a scoping project is returned, you MUST

deploy policies there.

• Action B (Code Scan): Search Terraform configurations for

google_monitoring_monitored_project resources to extract the

scoping project.

• Action C (Fallback): If ambiguous, ASK the user: "Are you using

a multi-project Cloud Monitoring Metric Scope? If so, what is the

scoping project ID?"

• Step 3: Pre-existing Policies Check: Avoid duplicates.
• Action: Scan the target directory to see if aggregated policies

already exist targeting the same metrics (grouped by

reasoning_engine_id or gen_ai_agent_name). Use

scan_duplicates.py to verify.

• Alert Policy Type Resource Files: You MUST list and read files under

references/ with names ending in _alert_policies.md to learn how to

configure alert policies based on type. By default you should configure all

of the following alert types UNLESS the user requests to generate explicit

alert policies and/or types. Follow their tables of content to help you find

the reference sections you need to read:

Alert Type | Reference File

:-------------- | :-------------

Reliability | reliability_alert_policies.md

Quality | quality_alert_policies.md

Cost | cost_alert_policies.md

Safety | safety_alert_policies.md

Security | security_alert_policies.md

5. Outputs & Formats

• Always configure the supported alerting policies for the target agent:
• For Reliability Monitoring: You MUST configure exactly five alerting

policies:

• Latency (anomaly monitoring)
• Error Rate - Fast Burn SLO (1-Hour Window)
• Error Rate - Slow Burn SLO (3-Day Window)
• Model Call Error Rate (SQL-based Log Analytics Alerting)
• Tool Call Error Rate (SQL-based Log Analytics Alerting)
• For Quality Monitoring: You MUST configure exactly three alerting

policies (Requires Vertex AI Online Monitors):

• Final Response Quality
• Tool Use Quality
• Hallucination
• For Cost Monitoring: You MUST configure exactly one cost alerting

policy:

• Rapid Token Burn Rate (anomaly monitoring)
• For Safety Monitoring: You MUST configure exactly one safety

alerting policy:

• High Model Armor Safety Policy Trigger Rate (SQL-based Log

Analytics Alerting)

• For Security Monitoring: You MUST configure exactly one security

alerting policy:

• High IAM Permission Denied Trigger Rate (SQL-based Log Analytics

Alerting)

• Terraform Only: Write the generated observability configuration ONLY as

Terraform (.tf) files (e.g., alerts.tf, variables.tf).

• You ONLY need to install Terraform if you're asked to deploy the

alerts AND there is no valid Terraform install. SQL-based alerting using

condition_sql requires the provider version >= 6.0.0 (or late 5.x

versions supporting the feature).

• If you are NOT asked to deploy the alerts you do not need to install

terraform.

• Dynamic Multi-Resource Alerting (No Single-Resource Pinning): You MUST

NOT hardcode specific agent IDs or resource name filters (e.g.,

{gen_ai_agent_name="{agent_name}"} or

metric.labels.agent_resource_name="{agent_name}") in alerting conditions

unless explicitly requested (e.g., "ONLY for this agent"). Merely mentioning

a specific agent name or ID in the request does NOT constitute an explicit

request to pin/filter; you MUST still default to dynamic grouping to cover

all agents. To cover all active agents in the project dynamically:

• For Reliability Metrics using PromQL: ALWAYS use grouping

aggregations. Group by gen_ai_agent_name (e.g., `by

(gen_ai_agent_name)`). Avoid filtering to a single ID/Name unless

requested.

• For Quality Metrics using Standard Threshold Filters: Omit the

agent_resource_name filter entirely. Configure the condition filter to

only target the monitored resource type

(aiplatform.googleapis.com/OnlineEvaluator) and metric type

(aiplatform.googleapis.com/online_evaluator/scores) globally for the

project.

• For Downstream Calls using SQL: Omit the ENDS_WITH filter

targeting a specific agent name. Instead, extract the agent identifier

(e.g., JSON_VALUE(resource.attributes, '$."cloud.resource_id"')) and

add it to the GROUP BY clause alongside the model or tool name.

• Directory Inference: Prefer the path explicitly provided by the user (if

any). Otherwise, deploy configuration files to target Terraform or SRE

folders (e.g. monitoring/, ops/, sre/). Use tools to locate where

alert policies or state pointers exist in the project, rather than blindly

writing to the root.

• Notification Channels: By default, never configure any notification

channels without user input. If the user explicitly provides a notification

channel in their prompt, configure the alerts to use it. If no notification

channel is provided, you MUST explicitly ask the user in your final response

if they would like to configure notification channels. **This is a mandatory

question and you MUST NOT omit it from your response. IMPORTANT** Do NOT

make assumptions about notification channels. If you search the codebase for

a notification channel you must ALWAYS confirm with the user before using

it.

• Plain English Response: You MUST include a plain English explanation for

what the alerts do in your response. This must explain in plain English what

the alert measures, how the algorithm works, and what a trigger indicates.

6. Output Verification

• Background Task Cleanup: You MUST check the status of all background

tasks that you spawn. Before completing your execution and returning your

final response, you MUST terminate or kill any active or hanging background

tasks (using the manage_task tool with action kill).

• Validate Configuration: Run the Config Linting tool to make sure all

the output files are written with the correct grammar and structure. See

details about the tool in the Tooling Scripts section below.

Tooling Scripts

Use the following scripts to discover agents, gather configuration details,

resolve duplicates, and validate configs:

• Agent Information Gathering: Streamlines discovery, environment auditing

(Metric Scopes, BQ Datasets, Notification Channels), table derivations (Log

& Trace), and Online Evaluator checks.

• Command: `python3 scripts/gather_agent_info.py --project-id {project_id}

--agent-name {agent_name}`

• Duplicate Check & Merge: Checks for pre-existing alerts in the target

folder to ensure changes are merged in-place rather than appended:

• Command: `python3 scripts/scan_duplicates.py {target_tf_dir}

--engine-var '${var.gen_ai_agent_name}'`

• Config Linting: Validates PromQL grammar, matching engine labels, and

HCL structure:

• Command: python3 scripts/lint_syntax.py {path_to_tf_file}
• Self-Correction Loop: If validation fails (exits non-zero or outputs

errors), you MUST read the command output, locate the line/file

containing the lint error, analyze the PromQL syntax or Terraform HCL

issue, apply adjustments in-place, and re-run the lint_syntax.py

validation. Repeat this loop until the validation script passes

successfully.

Gotchas & Behavioral Corrections

• Raw Error Boundaries: Explain that raw error counts or absolute failed

request count boundaries do not scale under changing traffic throughput.

Recommend ratio-based error rate alerts instead.

• Safe Threshold Modulation E2E Validation: When verifying a dynamic

metric threshold policy end-to-end, do NOT attempt to force real platform

errors. Instead, deploy the alert policy with standard safe bounds (Z-score

multiplier > 15), then temporarily update standard deviation Z-score limits

to a negative value (e.g. > -3) to trigger/verify the "Firing" state before

reverting. Always get confirmation before taking this action proactively.

• Expected Script Failures:
• scan_duplicates.py exiting with code 1: Parse the JSON

output for duplicate resource targets. Perform in-place upgrade edits,

then re-check until it passes with 0.

• Script Execution Failures & Self-Correction: If the execution of

utility scripts (such as gather_agent_info.py, check_telemetry.py,

create_online_monitor.py, analyze_traffic.py,

list_log_scope_table_names.py, or list_trace_scope_table_names.py)

fails unexpectedly, you MUST read and inspect the stdout/stderr logs or

error output. Analyze the error message and attempt to dynamically

correct parameters and retry execution before escalating or

falling back to manual plans. Consult the relevant domain-specific

reference file for detailed troubleshooting steps for specific scripts.

• Distribution Metric Aligner Constraint: Standard ALIGN_MEAN cannot be

applied to DELTA distribution metrics like online_evaluator/scores. You

MUST use percentile-based aligners (like ALIGN_PERCENTILE_50) to reduce

the score distribution into a comparable numeric stream.

• HCL Heredoc Interpolation: When referencing Terraform variables inside

PromQL or SQL queries (which are defined as strings), you MUST use the

${var.variable_name} syntax. Bare references like var.variable_name will

fail at deployment time.

• Avoid Recursive Directory Operations: You MUST NOT run recursive listing

or search commands (such as ls -R, find ., or raw recursive grep) from

the repository root if it contains a very large number of files, as this

will freeze your session. Always target specific subdirectories.
