getsentry/sentry-java is a Java and Android software development kit for sending application errors, events, and diagnostic information to Sentry. It is used by developers working with Java, Android, Kotlin, and other JVM-based applications to monitor software behavior. The catalogue rules, skills, instructions, and setting support workflows around this SDK.

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 | $0.02553 | $0.02553 |
| Opus 5.5 | $0.01021 | $0.01021 |
| Sonnet 5.5 | $0.00511 | $0.00511 |
| Haiku 4.5 | $0.00255 | $0.00255 |
Grade A, and why
sentry-java AGENTS.md scanned grade A with 0 findings 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 22d ago.
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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts

Domain-Specific Rules
This file covers the whole repository. Before working on a specific area, read the matching
rule file in .cursor/rules/:
| Rule | Read it when working on |
|---|---|
api |
Public API surface, binary compatibility, .api files, apiDump, IScope/IScopes/Sentry static API, protocol classes |
options |
SentryOptions, namespaced options, ExternalOptions, sentry.properties, ManifestMetadataReader, Spring Boot properties |
scopes |
Scope management, forking, lifecycle, ScopeType, thread-local storage, scope bleeding, Hub → Scopes migration |
deduplication |
Duplicate event detection, DuplicateEventDetectionEventProcessor, enableDeduplication |
offline |
Caching, envelope storage, network failure handling, retries, AsyncHttpTransport, EnvelopeCache, rate limiting |
feature_flags |
addFeatureFlag, FeatureFlagBuffer, maxFeatureFlags, LaunchDarkly and OpenFeature integrations |
metrics |
Sentry.metrics(), IMetricsApi, count/distribution/gauge, MetricsBatchProcessor |
queues |
Queue tracing, queue.publish/queue.process, enableQueueTracing, Kafka instrumentation, messaging span data |
continuous_profiling_jvm |
sentry-async-profiler, IContinuousProfiler, ProfileChunk, JFR files, ProfileLifecycle |
opentelemetry |
sentry-opentelemetry-*, agent vs agentless, span processing, sampling, context propagation |
new_module |
Adding a new integration or sample module |
e2e_tests |
System tests, sample applications, system-test-runner.py, mock Sentry server |
Rules can be combined — a tracing scope issue may need both scopes and opentelemetry.
There is no rule for Android profiling yet; read the sentry-android-core profiling code
directly and fetch related rules such as options, offline, or api as needed.
Project Overview
This is the Sentry Java/Android SDK - a comprehensive error monitoring and performance tracking SDK for Java and Android applications. The repository contains multiple modules for different integrations and platforms.
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.

sentry-java AGENTS.md is an instructions file published in the GitHub repository getsentry/sentry-java (1,357 stars, last pushed today), licensed MIT. It adds 2,553 tokens to every session, about $0.0102 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
