asc-crash-fetcher

asc-crash-fetcher

Manage TestFlight crash feedback from the App Store Connect API. Pulls crash submissions into a local SQLite database, downloads .ips crash logs to predictable paths, and tracks fix status — designed to be driven by both humans and AI agents.

Uses the TestFlight Feedback API (WWDC25) — betaFeedbackCrashSubmissions and betaCrashLogs endpoints from the App Store Connect API v4.2.

Features

• Multi-app support — monitor multiple bundle IDs from a single config
• SQLite crash database — local, queryable, zero infrastructure
• Automatic log download — .ips crash logs saved with stable integer filenames
• Retry missing logs — re-attempts download on every sync until the 120-day expiry
• Status tracking — new → investigating → fixed / wontfix / duplicate
• JSON output — every command supports --format json for machine consumption
• Claude Code skill — included SKILL.md for AI-assisted crash triage
• Project-local or global — ./asc-crashes/ per-project or ~/.asc-crashes/ global

Quick Start

Install from GitHub Releases

Download a prebuilt binary from Releases and place it on your PATH.

Install from source

cargo install --git https://github.com/jsvana/asc-crash-fetcher

Initialize and run

# Create a project-local data directory
asc-crash-fetcher init

# Or create a global one in ~/.asc-crashes
asc-crash-fetcher init --global

# Add your API credentials
$EDITOR asc-crashes/config.toml

# Verify your key works
asc-crash-fetcher apps

# Pull crashes and download logs
asc-crash-fetcher sync

# See what's unfixed
asc-crash-fetcher list --status new,investigating

# Look at a specific crash
asc-crash-fetcher show 3

# Mark it fixed
asc-crash-fetcher fix 3 --notes "Nil check in SettingsVC.swift:42"

Data Directory

The tool resolves its data directory in priority order:

1. --data-dir PATH — explicit override
2. ./asc-crashes/ — project-local (if config.toml exists there)
3. ~/.asc-crashes/ — global fallback

asc-crashes/
├── config.toml     # API credentials + app list
├── crashes.db      # SQLite database
└── logs/
    ├── 1.ips       # Crash logs keyed by local DB id
    ├── 2.ips
    └── ...

Configuration

[api]
issuer_id   = "your-issuer-id"
key_id      = "ABCDEF1234"
private_key = "AuthKey_ABCDEF1234.p8"  # path relative to data dir, absolute, or inline PEM

# Monitor one or more apps
[[apps]]
bundle_id = "com.example.app1"

[[apps]]
bundle_id = "com.example.app2"

Get your API key from App Store Connect → Integrations → App Store Connect API. The key needs at least App Manager role.

Commands

Command	Description
init [--global]	Create data directory with template config
apps	List apps visible to your API key
sync [--app BUNDLE]	Pull new crashes, download logs
list [--status S] [--since DATE] [--app BUNDLE] [--limit N]	List crashes with filters
show <id>	Full crash details + log preview
log <id>	Print absolute path to the .ips file
fix <id> [--notes "…"]	Mark as fixed
investigate <id>	Mark as under investigation
wontfix <id> [--notes "…"]	Mark as won't fix
duplicate <id> --of <other>	Mark as duplicate of another crash
reopen <id>	Reset status to "new"
stats [--app BUNDLE]	Counts by status, device, OS

All commands accept --format json for structured output.

JSON Output

Every command supports --format json, printing structured data to stdout while keeping status messages on stderr:

asc-crash-fetcher sync --format json | jq '.new_crashes[].log_path'
asc-crash-fetcher list --status new --format json | jq '.crashes[] | {id, device_model, os_version}'
asc-crash-fetcher stats --format json

Claude Code Integration

This project ships as a Claude Code plugin with an Agent Skill for AI-assisted crash triage.

Install via Claude Code plugin marketplace

/plugin marketplace add jsvana/asc-crash-fetcher
/plugin install testflight-crash-triage@asc-crash-fetcher

Or install the skill manually

# Personal skill (all projects)
mkdir -p ~/.claude/skills/testflight-crash-triage
cp skills/testflight-crash-triage/SKILL.md ~/.claude/skills/testflight-crash-triage/

# Project skill (this project only)
mkdir -p .claude/skills/testflight-crash-triage
cp skills/testflight-crash-triage/SKILL.md .claude/skills/testflight-crash-triage/

Once installed, Claude will automatically use the skill when you ask about TestFlight crashes, crash triage, or .ips crash logs. You can also be direct:

Sync my TestFlight crashes and analyze any new ones.
