PostHogCLAUDE.mdduckgres / client-compat
PostHog/duckgres/scripts/client-compat/CLAUDE.md
Docker Compose-based test framework that runs real PostgreSQL client libraries against duckgres and collects results into a DuckDB database. Lives under scripts/client-compat/. Key design point: the gatherer does NOT track which clients are done. The justfile handles all lifecycle coordination via docker wait. This avoids hangs when clients crash before reporting. Clients report results via HTTP to $RESULTS_URL (defaults to http://results-gatherer:8080): All reporting is fire-and-forget (errors silently swallowed) so clients also work standalone without the gatherer. Use report_client.py (copied into…

SentryCLAUDE.mdsentry-unreal
getsentry/sentry-unreal/CLAUDE.md
This project is the Sentry SDK for Unreal Engine which provides crash and error monitoring as well as performance tracking for games built with Unreal Engine. It wraps multiple Sentry SDKs for supported platforms (sentry-native for Windows/Linux/macOS/Xbox/WinGDK/PlayStation/Nintendo, sentry-cocoa for macOS/iOS, sentry-java for Android) into a single Unreal Engine plugin and extends them with Unreal Engine-specific functionality. For sentry-native platforms SDK supports multiple crash handler backends. The backend is selected in Sentry.Build.cs at build time via the UseNativeBackend setting configured in…

If STACK.md does not exist at the repo root, this is a fresh install and nothing has been configured. Before doing anything else in this session, greet the user with exactly this shape (adapt the words, keep the content): This repo is the on-call kit — playbooks, comms, and a self-improving incident log for running Claude-assisted on-call in your team's Slack channel. Nothing is active yet: no watching, no schedules, no paging. One thing to know up front: this agent…
GitHubCLAUDE.mdgh-aw-firewall
github/gh-aw-firewall/CLAUDE.md
awf (Agentic Workflow Firewall, package @github/awf) is a CLI that wraps any command in a sandboxed Docker network. It provides L7 (HTTP/HTTPS) egress control using Squid proxy, restricting network access to a whitelist of approved domains while giving the agent access to the host workspace and selected system paths via chroot and selective bind mounts. The system is orchestrated by src/cli.ts and managed by src/docker-manager.ts. Squid, the primary agent, and the general API proxy are the baseline services; private-repository enclaves…

AWSCLAUDE.mdvisual-asset-management-system / backend
awslabs/visual-asset-management-system/backend/CLAUDE.md
Auto-loaded when Claude Code works within backend/. Authoritative guide for Lambda handler development, Pydantic model creation, authorization enforcement, DynamoDB access, and validators. Testing details: backend/tests/CLAUDE.md. Copy-paste skeletons for a new handler / model / test file: backend/HANDLER_TEMPLATES.md. Update this tree when adding new handler domains, model files, or test directories (root CLAUDE.md Rule 11).
AWSCLAUDE.mdvisual-asset-management-system / backendPipelines
awslabs/visual-asset-management-system/backendPipelines/CLAUDE.md
This is the Claude Code steering document for the backendPipelines/ tree. It covers the pipeline architecture, S3 output-path conventions, assetId threading, and the end-to-end checklist for adding a new processing pipeline. For project-wide context, see the root CLAUDE.md. VAMS supports four pipeline execution types (PIPELINE_EXECUTION_TYPES in backend/backend/models/pipelines.py): Lambda (sync or async invocation of a Lambda function), SQS (async message to an SQS queue), EventBridge (async event to an EventBridge bus), and DeadlineCloud (an AWS Deadline Cloud job). SQS and EventBridge…
AWSCLAUDE.mdvisual-asset-management-system / tests
awslabs/visual-asset-management-system/backend/tests/CLAUDE.md
Auto-loaded when Claude Code works within backend/tests/. Covers pytest configuration, mock module hierarchy, per-handler conftest patterns, and event-shape conventions for backend unit tests. For handler patterns, see backend/CLAUDE.md. The root backend/conftest.py performs critical setup before every test: tests/mocks/ contains stand-in modules that are loaded in place of the real implementations. Layout mirrors the handler package tree: When adding a new dependency that a handler imports at module load time, add a matching mock module here if the real one requires…
About CLAUDE.md
What is CLAUDE.md?
A file Claude Code reads at the start of every session. It holds the commands, conventions and warnings the agent needs for this project.
Where does it go?
At the repository root. Claude Code also reads CLAUDE.md files in subdirectories when it works there.
What should it contain?
Build and test commands, the project's layout, conventions that aren't obvious from the code, and mistakes to avoid. Short files tend to work better than long ones.
CLAUDE.md or AGENTS.md?
Claude Code reads CLAUDE.md; most other agents read AGENTS.md. Many projects keep one and point the other at it.
