Create Crash Ticket

Create Crash Ticket

Create a Jira Bug ticket from a Firebase Crashlytics issue ID. Fetches crash/ANR details (stack trace, device info, impact metrics) from Crashlytics and creates a structured Jira ticket in the AND project.

Usage

/create-crash-ticket <issueId>
/create-crash-ticket 66f1a2b3c4d5e6f7a8b9c0d1

Arguments

Configuration

All steps below reference these values — if any change, update them here only.

• Firebase App ID (APP_ID): 1:268821755439:android:9b611c50c9f7a503
• Firebase Project (PROJECT): megapoc-25443
• Jira Project Key: AND
• Jira Base URL (JIRA_BASE_URL): Read from environment variable JIRA_BASE_URL
• Jira Auth: Bearer token from environment variable JIRA_ACCESS_TOKEN

Steps

Step 1 -- Validate input and environment

1a. Check environment variables. Before doing anything else, verify that the required environment variables are set by running:

python3 -c "
import os, sys
missing = [v for v in ('JIRA_BASE_URL', 'JIRA_ACCESS_TOKEN') if not os.environ.get(v)]
if missing:
    print(f'ERROR: Missing environment variables: {", ".join(missing)}', file=sys.stderr)
    sys.exit(1)
print('Environment OK')
"

If any are missing, stop immediately and tell the user which variables need to be set.

1b. Extract issue ID. Extract the Crashlytics issue ID from the user's input. The issue ID is typically a hex string. If the user provides a Crashlytics console URL, extract the issue ID from the URL path segment after /issues/.

If no issue ID can be determined, ask the user to provide one.

Step 2 -- Fetch issue details

Call the mcp__plugin_firebase_firebase__crashlytics_get_issue tool:

From the response, extract:

• errorType: one of "ANR", "FATAL", or "NON_FATAL"
• title: issue title (e.g., class/method name)
• subtitle: issue subtitle (e.g., human-readable description)
• variants: the array of variants (each has id, sampleEvent, uri)
• variantCount: the length of the variants array
• signals: array of signal objects (e.g., SIGNAL_FRESH, SIGNAL_REGRESSED, SIGNAL_EARLY, SIGNAL_REPETITIVE), each with a description string
• firstSeenVersion: the app version where this issue was first observed
• lastSeenVersion: the most recent app version where this issue was observed

Step 3 -- Fetch impact metrics

Use the topVariants report, which supports filtering by issueId directly and works reliably regardless of issue ranking.

Make two calls in parallel — one for the last 7 days and one for the last 90 days:

Call 1 — Last 7 days:

Call 2 — Last 90 days:

IMPORTANT: Always specify intervalStartTime and intervalEndTime explicitly. Without explicit times, the API defaults to calendar-day-aligned boundaries which produces different counts than the console shows.

From each response, extract for each variant group:

• variant ID (from the group's variant identifier)
• metrics[0].eventsCount: occurrences for this variant
• metrics[0].impactedUsersCount: affected users for this variant

Compute totals for each time window by summing across all variant groups:

• eventsCount7d / eventsCount90d: sum of all variant eventsCount values
• impactedUsersCount7d / impactedUsersCount90d: sum of all variant impactedUsersCount values

Use the 7-day response (Call 1) to determine the primary variant and per-variant metrics for the Variants table. The first entry (highest event count) is the primary variant. Record its variant ID as primaryVariantId.

If variantCount > 1, join the variant metrics with the variants array from Step 2 by variant ID to get each variant's uri (Crashlytics console link).

If either call fails, default the corresponding values to "unknown".

Step 4 -- Fetch stack trace and device info

Call the mcp__plugin_firebase_firebase__crashlytics_list_events tool:

• If variantCount > 1 and primaryVariantId is known: {"issueId": "<issueId>", "issueVariantId": "<primaryVariantId>"}
• Otherwise: {"issueId": "<issueId>"}

This ensures we get the stack trace for the highest-impact variant, not just the most recent event (which might be from a low-impact variant).

From the first event in the response, extract:

• device.displayName: device model display name (e.g., "vivo (V2529)")
• operatingSystem.displayVersion: Android version number (e.g., "16")
• version.displayVersion: app version (e.g., "16.0.1(260701146)(1801451b03)")
• threads: full stack trace text (multi-line string). Include every frame — do not omit or truncate any frames. Copy the entire threads content exactly as returned.
• blameFrame.symbol: the blamed function name

If the events list is empty, note that no event data is available and proceed with what was gathered in Steps 2 and 3.

Note: Steps 3 and 4 are independent — run them in parallel for faster execution.

Step 5 -- Build Jira ticket fields

Title

The title MUST be specific to the root cause visible in the stack trace. Never use generic descriptions like "slow operations in main thread". Instead, identify the key class and method from the stack trace.

How to find the key class/method for the title:

1. Look at the threads stack trace from Step 4.
2. Find the first frame that belongs to the app's own code (packages starting with mega.privacy.android, nz.mega.sdk, or the app's own classes). Ignore Android framework frames (android.os.*, java.lang.*, androidx.*) and native frames (syscall, pthread_*, std::*).
3. Extract the class name and method name from that frame.
4. Use the format: ClassName.methodName

Title format:

• If errorType is "ANR":
  • Title: [ANR] {ClassName.methodName}
  • Example: [ANR] UserAttributeDatabaseUpdater.checkMyChatFilesFolderRequest
  • If no app-level frame is found, fall back to blameFrame.symbol
• If errorType is "FATAL" or "NON_FATAL":
  • Title: [Crash] {ExceptionClass} in {ClassName.methodName}
  • Example: [Crash] NullPointerException in TransferService.onStartCommand
  • Use the issue title for the exception class and the first app-level frame for the location. If title is very long (contains file paths like [libmega.so]), use the blameFrame.symbol or the exception class only.

Component

• If errorType is "ANR":
  • Component: {"name": "Firebase Crashlytics - ANR"}
• If errorType is "FATAL" or "NON_FATAL":
  • Component: {"name": "Crashlytics"}

Description (Jira Wiki Markup)

Build the description body using Jira wiki markup format:

Single-variant template (when variantCount == 1):

h3. Crashlytics Issue
[View in Crashlytics|https://console.firebase.google.com/project/megapoc-25443/crashlytics/app/android:mega.privacy.android.app/issues/<issueId>?time=last-seven-days]

h3. Stack Trace (Primary Variant)
{code}
<threads content>
{code}

Multi-variant table rules:

• Cap the table at 10 rows. If there are more than 10 variants, add a note below the table: _...and N more variants. [View all in Crashlytics|<issue uri>]_
• Variant URIs come from the variants array in the Step 2 response, joined by variant ID with the metrics from Step 3b.
• If a variant has metrics but no matching URI, omit the Link column for that row.

Map errorType to the display string:

• "ANR" -> ANR
• "FATAL" -> Fatal Crash
• "NON_FATAL" -> Non-Fatal Crash

Signals & Versions section rules:

• List signal names as a comma-separated string (e.g., Fresh, Regressed). Use human-readable names: SIGNAL_FRESH → Fresh, SIGNAL_REGRESSED → Regressed, SIGNAL_EARLY → Early, SIGNAL_REPETITIVE → Repetitive.
• If the signals array is empty or absent, set Signals to None and omit the description lines.
• Always include firstSeenVersion and lastSeenVersion even when there are no signals.

IMPORTANT: Include the complete stack trace — do not omit or summarize any frames. Copy every frame exactly as returned by the Crashlytics event.

Full Jira payload

{
    "fields": {
        "project": {"key": "AND"},
        "summary": "<title from above>",
        "issuetype": {"name": "Bug"},
        "components": [<component from above>],
        "description": "<description from above>",
        "customfield_10500": {"value": "OPEX"},
        "customfield_10501": {"value": "Cloud/Default"}
    }
}

Step 6 -- Check for existing Jira ticket

Before creating a new ticket, search Jira to see if a ticket already exists for this Crashlytics issue.

Run a Python script using the Bash tool to search Jira via JQL:

python3 << 'PYEOF'
import urllib.request, urllib.parse, json, os, sys

token = os.environ.get('JIRA_ACCESS_TOKEN')
if not token:
    print('ERROR: JIRA_ACCESS_TOKEN environment variable is not set', file=sys.stderr)
    sys.exit(1)

jira_base_url = os.environ.get('JIRA_BASE_URL')
if not jira_base_url:
    print('ERROR: JIRA_BASE_URL environment variable is not set', file=sys.stderr)
    sys.exit(1)

issue_id = "<issueId>"
jql = f'project = "AND" AND description ~ "{issue_id}" AND status != Closed'
params = urllib.parse.urlencode({'jql': jql, 'fields': 'key,summary,status'})
url = f'{jira_base_url}/rest/api/2/search?{params}'

req = urllib.request.Request(url, headers={
    'Authorization': f'Bearer {token}',
    'Content-Type': 'application/json'
}, method='GET')

try:
    resp = urllib.request.urlopen(req)
    result = json.loads(resp.read())
    print(json.dumps(result))
except urllib.error.HTTPError as e:
    error_body = e.read().decode('utf-8', errors='replace')
    print(f'ERROR {e.code}: {error_body}', file=sys.stderr)
    sys.exit(1)
PYEOF

From the response, check total:

• If total > 0 (duplicate found):

  • Extract the first issue's key, summary, and status.name
  • Print to the user:

    Existing Jira ticket found for this Crashlytics issue:
      <ticketKey>: <summary>
      Status: <status>
      URL: <JIRA_BASE_URL>/browse/<ticketKey>
    

  • Skip Step 7 (do not create a new ticket)
  • Proceed to Step 8 (annotate Crashlytics issue) using the existing ticket key
  • After Step 8, skip to Step 9 to display results

• If total == 0: proceed to Step 7 to create the ticket

Step 7 -- Create Jira ticket

CRITICAL: Do NOT use curl for the Jira API call. The JIRA_ACCESS_TOKEN environment variable contains a + character that gets corrupted by shell expansion in curl. Use a Python heredoc script via the Bash tool instead.

Run a Python script using the Bash tool with a heredoc to avoid shell quoting issues with the multi-line description body:

python3 << 'PYEOF'
import urllib.request, json, os, sys

token = os.environ.get('JIRA_ACCESS_TOKEN')
if not token:
    print('ERROR: JIRA_ACCESS_TOKEN environment variable is not set', file=sys.stderr)
    sys.exit(1)

description = """<description from Step 5>"""

payload = {
    "fields": {
        "project": {"key": "AND"},
        "summary": "<title from Step 5>",
        "issuetype": {"name": "Bug"},
        "components": [<component from Step 5>],
        "description": description,
        "customfield_10500": {"value": "OPEX"},
        "customfield_10501": {"value": "Cloud/Default"}
    }
}

jira_base_url = os.environ.get('JIRA_BASE_URL')
if not jira_base_url:
    print('ERROR: JIRA_BASE_URL environment variable is not set', file=sys.stderr)
    sys.exit(1)

url = f'{jira_base_url}/rest/api/2/issue'
data = json.dumps(payload).encode('utf-8')

req = urllib.request.Request(url, data=data, headers={
    'Authorization': f'Bearer {token}',
    'Content-Type': 'application/json'
}, method='POST')

try:
    resp = urllib.request.urlopen(req)
    result = json.loads(resp.read())
    print(json.dumps({'key': result['key'], 'id': result['id'], 'self': result['self']}))
except urllib.error.HTTPError as e:
    error_body = e.read().decode('utf-8', errors='replace')
    print(f'ERROR {e.code}: {error_body}', file=sys.stderr)
    sys.exit(1)
PYEOF

Important notes for building the Python command:

• Build the description as a Python variable (triple-quoted string), not inline in the dict.
• Escape any characters that would break the Python string literals.

If the Jira API call fails, display the error to the user and stop.

From the response, extract the key field (e.g., AND-23100). This is the Jira ticket key.

Step 8 -- Annotate Crashlytics issue

This step is reached both after creating a new ticket (Step 7) and when an existing ticket was found (Step 6).

First, check if the Crashlytics issue already has a note linking to this Jira ticket. Call the mcp__plugin_firebase_firebase__crashlytics_list_notes tool:

Check the returned notes for any that contain the ticket key (e.g., AND-23100).

• If no existing note contains the ticket key: call the mcp__plugin_firebase_firebase__crashlytics_create_note tool:

  Parameter	Value
  appId	APP_ID
  issueId	<issueId>
  note	Jira ticket: <JIRA_BASE_URL>/browse/<ticketKey>

• If a note already contains the ticket key: skip note creation and note that the annotation already exists.

Step 9 -- Display results

Present a formatted summary report to the user using a markdown table. Use the appropriate template below depending on the outcome.

If an existing ticket was found (from Step 6):
