    • Bash(oci:*)
    • Grep

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • docs.oracle.com
    • hooks.slack.com

    Also links to:

    • ocistatus.oraclecloud.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

Context cost

Oraclecloud Webhooks Events loads about 2.2k tokens when it runs, and up to ~2.7k if it reads all its reference files. Until then it costs about 86 tokens; SKILL.md has 507 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~86
When it runs · the whole SKILL.md, loaded when a task matches
~2.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Oracle Cloud Webhooks & Events

Overview

Build event-driven workflows using the OCI Events service, Oracle Notification Service (ONS), and OCI Functions. OCI Events monitors resource state changes across your tenancy and fires rules that route events to ONS topics, streaming, or Functions. This skill covers event rule creation, ONS topic/subscription setup, event pattern matching syntax, and Functions integration.

Purpose: Create reliable event-driven pipelines that react to OCI resource changes in real time.

Prerequisites

  • OCI Python SDK — pip install oci
  • OCI config file at ~/.oci/config with valid credentials (user, fingerprint, tenancy, region, key_file)
  • IAM policies granting access to Events, ONS, and Functions:
    • Allow group EventAdmins to manage cloudevents-rules in compartment <name>
    • Allow group EventAdmins to manage ons-topics in compartment <name>
    • Allow group EventAdmins to use fn-function in compartment <name>
  • Compartment OCID for the target compartment
  • Python 3.8+

Instructions

Step 1: Create an ONS Topic and Subscription

Create a notification topic that will receive events, then subscribe an endpoint (email, HTTPS, PagerDuty, or Slack via HTTPS):

python
import oci

config = oci.config.from_file("~/.oci/config")
ons_control = oci.ons.NotificationControlPlaneClient(config)
ons_data = oci.ons.NotificationDataPlaneClient(config)

# Create a topic
topic_response = ons_control.create_topic(
    oci.ons.models.CreateTopicDetails(
        name="infra-alerts",
        compartment_id="ocid1.compartment.oc1..example",
        description="Infrastructure lifecycle alerts"
    )
)
topic_id = topic_response.data.topic_id
print(f"Topic created: {topic_id}")

# Subscribe an HTTPS endpoint (e.g., Slack incoming webhook)
subscription = ons_data.create_subscription(
    oci.ons.models.CreateSubscriptionDetails(
        topic_id=topic_id,
        compartment_id="ocid1.compartment.oc1..example",
        protocol="HTTPS",
        endpoint="https://hooks.slack.com/services/YOUR/SLACK/WEBHOOK"
    )
)
print(f"Subscription: {subscription.data.id} ({subscription.data.lifecycle_state})")
Step 2: Create an Events Rule

Events rules use a condition block that matches on eventType, compartmentId, and optional attribute filters. The condition syntax is JSON, not HCL:

python
events_client = oci.events.EventsClient(config)

rule = events_client.create_rule(
    oci.events.models.CreateRuleDetails(
        display_name="instance-state-changes",
        compartment_id="ocid1.compartment.oc1..example",
        description="Fire on compute instance lifecycle changes",
        is_enabled=True,
        condition='{"eventType":["com.oraclecloud.computeapi.launchinstance.end","com.oraclecloud.computeapi.terminateinstance.end","com.oraclecloud.computeapi.instanceaction.end"]}',
        actions=oci.events.models.ActionDetailsList(
            actions=[
                oci.events.models.ActionDetails(
                    action_type="ONS",
                    topic_id=topic_id,
                    is_enabled=True,
                    description="Notify infra-alerts topic"
                )
            ]
        )
    )
)
print(f"Rule created: {rule.data.id}")
Step 3: Common Event Types Reference

Use these exact eventType strings in your rule conditions:

CategoryEvent TypeFires When
Computecom.oraclecloud.computeapi.launchinstance.endInstance launch completes
Computecom.oraclecloud.computeapi.terminateinstance.endInstance terminated
Computecom.oraclecloud.computeapi.instanceaction.endStop/start/reboot finishes
Storagecom.oraclecloud.objectstorage.createbucketNew bucket created
Storagecom.oraclecloud.objectstorage.deleteobjectObject deleted
Identitycom.oraclecloud.identitycontrolplane.createuserNew user created
Identitycom.oraclecloud.identitycontrolplane.updatepolicyIAM policy modified
Auditcom.oraclecloud.audit.eventAny auditable action
Step 4: Route Events to a Function

For complex processing, route events to an OCI Function instead of (or in addition to) ONS:

python
# Create a rule that invokes a Function
fn_rule = events_client.create_rule(
    oci.events.models.CreateRuleDetails(
        display_name="bucket-change-processor",
        compartment_id="ocid1.compartment.oc1..example",
        is_enabled=True,
        condition='{"eventType":["com.oraclecloud.objectstorage.createobject","com.oraclecloud.objectstorage.deleteobject"]}',
        actions=oci.events.models.ActionDetailsList(
            actions=[
                oci.events.models.ActionDetails(
                    action_type="FAAS",
                    function_id="ocid1.fnfunc.oc1.iad.example",
                    is_enabled=True,
                    description="Process bucket changes"
                )
            ]
        )
    )
)
Step 5: Verify the Pipeline

List active rules and test by triggering an event:

text
# List event rules via CLI
oci events rule list --compartment-id ocid1.compartment.oc1..example --all

# Check ONS subscription confirmation status
oci ons subscription list --compartment-id ocid1.compartment.oc1..example --topic-id <topic-ocid>
Show full SKILL.md (222 more words)Show less

Output

Successful completion produces:

  • An ONS topic with at least one confirmed subscription (email, HTTPS, or PagerDuty)
  • One or more Events rules with condition filters matching target event types
  • Verified event delivery — triggering a matched action (e.g., stopping an instance) delivers a notification to the subscribed endpoint

Examples

Quick event rule via CLI:

bash
# Create a rule that fires on all audit events in a compartment
oci events rule create \
  --compartment-id ocid1.compartment.oc1..example \
  --display-name "audit-all" \
  --is-enabled true \
  --condition '{"eventType":["com.oraclecloud.audit.event"]}' \
  --actions '{"actions":[{"actionType":"ONS","topicId":"ocid1.onstopic.oc1.iad.example","isEnabled":true}]}'

List all event types available:

python
import oci

config = oci.config.from_file("~/.oci/config")
events_client = oci.events.EventsClient(config)

# Event types are documented — no list API exists.
# Reference: https://docs.oracle.com/en-us/iaas/Content/Events/Reference/eventsproducers.htm
