What is crashlytics-crash-report?

A crash-analysis tool for Firebase Crashlytics, a service that records crashes from mobile apps. It chooses Android or iOS analysis from the saved configuration.

Fetching and analyzing Crashlytics crashes, checking related code history, and producing a validated report in the configured format.

It brings crash data, repository history, and code investigation into one report instead of leaving the cause to be inferred from a stack trace alone.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add IvanLutsenko/awac-ai-agent-plugins --skill crash-report

Clone the repo

git clone --depth 1 https://github.com/IvanLutsenko/awac-ai-agent-plugins

Made for: Claude Code.

Or install crashlytics, the plugin that ships this one along with the rest of its 10 skills, 5 commands, 5 agents.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.01730
Opus 5.5	$0.00000	$0.00692
Sonnet 5.5	$0.00000	$0.00346
Haiku 4.5	$0.00000	$0.00173

Security

Grade B, and why

crashlytics-crash-report scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/check-prerequisites.sh, scripts/fetch-crash-data.py, scripts/validate-report.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

How it starts

The opening of the file, as written. The whole thing — 184 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Converted from Claude Code command /crash-report. Review and adapt: hooks and MCP tool IDs may need manual mapping for Codex. Helper scripts ship in this skill's own scripts/ directory. Replace <this skill directory> with the path Codex reported when it loaded this skill — a bare relative path would resolve against the repository under review instead.

Crash Analysis

Unified crash analysis command. Reads default_platform from config and calls the right agents.

Step 0: Config + Platform

1. Check config:
   Glob: .claude/crashlytics.local.md

2. If config exists → Read it, parse YAML frontmatter.
   Set PLATFORM = default_platform (android | ios)

3. If config NOT found → auto-create with defaults:
   Bash: mkdir -p .claude && cat <<'EOF' > .claude/crashlytics.local.md
   ---
   language: en
   default_branch: master   # local branch name; plugin uses origin/<this> for git blame
   default_platform: android
   forensics_model: opus
   output_format: both
   firebase_project_id: ""
   firebase_app_id_android: ""
   firebase_app_id_ios: ""
   ---

   # Crashlytics Plugin Config

   Auto-created with defaults. Run `/crash-config` to customize.
   EOF

   Set PLATFORM = android
   Inform user: "Config created at `.claude/crashlytics.local.md` (defaults: android, origin/master, opus). Run `/crash-config` to customize."

Config values used throughout:

PLATFORM → which agents to call + console URL format
default_branch → local branch name; analysis runs on origin/<default_branch>
forensics_model → model for forensics agent (default: opus)
output_format → both / detailed_only / jira_only
firebase_project_id, firebase_app_id_{PLATFORM} → skip auto-detect if set

Step 0.5: Prerequisites Check (cached)

Skip if .claude/crashlytics-prereqs-ok exists. Otherwise run and cache on success.

Bash: test -f .claude/crashlytics-prereqs-ok && echo "CACHED_OK"

If not cached:
  Bash: <this skill directory>/scripts/check-prerequisites.sh
  Parse output: OK → pass, MISSING → fail with fix instruction
  If ALL OK → Bash: touch .claude/crashlytics-prereqs-ok
  If any MISSING → show checklist, degrade gracefully (do NOT cache)

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

crashlytics-crash-report is a skill published in the GitHub repository IvanLutsenko/awac-ai-agent-plugins (3 stars, last pushed 5d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,730 tokens. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
