2. Event Analysis

• List events for specific issues
• Retrieve event details with stack traces
• Debug source map issues
• Analyze error patterns

3. Project Monitoring

• List organization projects
• Get project health statistics
• View error trends
• Monitor release health

4. Tag Analysis

• View tag distributions

• Filter issues by tag values

Automatic Features

• Rate Limiting: Respects Sentry API rate limits
• Retry Logic: Automatic retry on transient errors
• Environment Detection: Flexible environment variable pattern matching
• Result Formatting: Markdown tables, JSON, or summary text
• Error Handling: Clear, actionable error messages

Environment Variables

This skill uses environment variables managed by jelly-dotenv. See skills/jelly-dotenv/SKILL.md for configuration details.

Required variables:

• SENTRY_AUTH_TOKEN - Your Sentry authentication token (org or personal)
• SENTRY_ORG or SENTRY_ORGANIZATION - Organization slug

Optional variables:

• SENTRY_PROJECT - Default project slug
• SENTRY_REGION - API region: us (default), de
• SENTRY_TIMEOUT - Request timeout in ms (default: 30000)

Variables can be configured in either:

• skills/jelly-dotenv/.env (skill-common, highest priority)
• Project root /.env (project-specific, fallback)

Configuration

Environment Variables

The skill automatically detects Sentry credentials using flexible pattern matching:

# ✅ Standard naming (recommended)
SENTRY_AUTH_TOKEN=sntrys_your_token_here
SENTRY_ORG=my-organization
SENTRY_PROJECT=my-project

# ✅ Alternative naming
SENTRY_ORGANIZATION=my-organization
SENTRY_TOKEN=sntrys_your_token_here

# ✅ Wildcard patterns (auto-detected)
PROD_SENTRY_TOKEN=sntrys_your_token_here
PROD_SENTRY_ORG=my-organization

# ✅ Optional settings
SENTRY_REGION=us          # us (default), de
SENTRY_TIMEOUT=30000      # Request timeout in ms

Regional Endpoints

Supports US and EU (Germany) regions:

# US (default)
SENTRY_REGION=us
# Base URL: https://sentry.io/api/0/

# Germany/EU
SENTRY_REGION=de
# Base URL: https://de.sentry.io/api/0/

Security Policy

Authentication

• Bearer Token: Authorization header with auth token
• Credentials: Loaded from environment variables only
• Logging: Tokens automatically redacted in logs

Permissions

• Org Tokens: Recommended for CI/CD and automation
• Personal Tokens: Bound to user permissions
• Scopes: Configure minimal required scopes

Data Access

• Read Operations: Primary focus (GET requests)

Not Found Errors (404)

• Invalid organization, project, or issue ID
• Action: Verify resource identifiers

Rate Limit Errors (429)

• Too many requests
• Action: Wait and retry (automatic backoff)

Output Formats

Markdown (Default)

• Formatted tables with issue details

Bash Helper Functions

For command-line usage with jelly-dotenv:

# Load environment variables from jelly-dotenv (with fallback to project root)
source skills/jelly-dotenv/load-env.sh

# Determine base URL
if [ "${SENTRY_REGION:-us}" = "de" ]; then
    SENTRY_BASE_URL="https://de.sentry.io"
else
    SENTRY_BASE_URL="https://sentry.io"
fi

# Sentry API curl helper
sentry-curl() {
    local endpoint="$1"
    shift

        -H "Authorization: Bearer ${SENTRY_AUTH_TOKEN}" \
        -H "Content-Type: application/json" \
        "$@" \
        "${SENTRY_BASE_URL}/api/0${endpoint}" | jq .
}

# List unresolved issues
sentry-issues() {
    local query="${1:-is:unresolved}"
    sentry-curl "/organizations/${SENTRY_ORG}/issues/?query=${query}"
}

# Get issue details
sentry-issue() {
    local issue_id="$1"
    sentry-curl "/organizations/${SENTRY_ORG}/issues/${issue_id}/"
}

# List issue events
sentry-events() {
    local issue_id="$1"
    local limit="${2:-10}"
    sentry-curl "/organizations/${SENTRY_ORG}/issues/${issue_id}/events/?limit=${limit}"
}

# List projects
sentry-projects() {
    sentry-curl "/organizations/${SENTRY_ORG}/projects/"
}

# Resolve issue
sentry-resolve() {
    local issue_id="$1"
    sentry-curl "/organizations/${SENTRY_ORG}/issues/${issue_id}/" \
        -X PUT -d '{"status": "resolved"}'
}

# Ignore issue
sentry-ignore() {

Quick Aliases

Add to your ~/.bashrc or ~/.zshrc:

# Sentry quick commands
alias sentry-unresolved='sentry-issues "is:unresolved"'
alias sentry-new='sentry-issues "is:unresolved firstSeen:-24h"'
alias sentry-critical='sentry-issues "is:unresolved level:fatal"'

Usage:

# List unresolved issues
sentry-issues

# Get specific issue
sentry-issue 123456

# List events for issue
sentry-events 123456 20

# List projects
sentry-projects

# Resolve an issue
sentry-resolve 123456

# Search for specific errors
sentry-issues "TypeError is:unresolved"

Query Syntax

Sentry supports a powerful search syntax:

Status Filters

• is:unresolved - Unresolved issues
• is:resolved - Resolved issues
• is:ignored - Ignored issues

Time Filters

• firstSeen:-24h - First seen in last 24 hours
• lastSeen:-1w - Last seen in past week
• age:-30d - Created in last 30 days

Level Filters

• level:error - Error level issues
• level:fatal - Fatal/crash level
• level:warning - Warning level

Assignment

• is:assigned - Assigned to someone
• is:unassigned - Not assigned
• assigned:me - Assigned to current user

Combine Filters

# Critical unresolved issues from today
sentry-issues "is:unresolved level:fatal firstSeen:-24h"

# Unassigned errors from past week
sentry-issues "is:unresolved is:unassigned lastSeen:-1w"

Integration with Claude Code

This skill activates automatically when users mention:

• "sentry"
• "error tracking"
• "issues"
• "exceptions"
• "crashes"
• "error monitoring"

The skill will:

1. Load Sentry credentials from .env
2. Execute the requested query
3. Format results as Markdown tables
4. Provide actionable error messages if something fails

Limitations

• API Rate Limits: Subject to Sentry's rate limiting
• Token Expiry: Personal tokens don't expire, org tokens may
• Data Retention: Limited by Sentry plan retention period
• Project Scope: Single organization per configuration

Troubleshooting

"Configuration error: SENTRY_AUTH_TOKEN is required"

Solution: Add auth token to .env file:

SENTRY_AUTH_TOKEN=sntrys_your_token_here
SENTRY_ORG=my-organization

"Authentication failed (401)"

Solution:

1. Verify token is correct
2. Check token hasn't been revoked
3. Ensure token has required scopes

"Organization not found (404)"

Solution: Verify SENTRY_ORG matches your organization slug (not display name)

"Permission denied (403)"

Solution:

1. Check token scopes include required permissions
2. Verify user has access to the organization/project

Creating Auth Tokens

Organization Auth Token (Recommended)

1. Go to Settings > Developer Settings > Internal Integrations
2. Create a new Internal Integration
3. Configure required permissions:
   • Project: Read
   • Issue & Event: Read (or Admin for updates)
   • Organization: Read
4. Copy the token

Personal Auth Token

1. Go to Account > API > Auth Tokens
2. Click "Create New Token"
3. Select required scopes
4. Copy the token
