Official Flutter team Agent Skills for AI coding agents building Flutter apps, fixing layout issues, adding widget and integration tests, creating widget previews, applying layered architecture, routing, localization, JSON serialization, and HTTP workflows.

Official Mapbox MCP server for geocoding, POI search, routing, travel-time matrices, isochrones, static maps, and geospatial calculations in Claude.

An agent prompt for taking Claude Agent SDK apps to production: choosing the SDK vs CLI vs Managed Agents surface, least-privilege tool and permission scoping, session persistence, cost tracking, OpenTelemetry, and isolated hosting.

An agent prompt for curating an organization's Agent Skills: reviewing each SKILL.md name and description, scope (personal, project, or plugin) and precedence, per-skill allowed-tools, and whether Claude or the user invokes it.

A reusable agent prompt that reviews a Claude Code auto mode setup: whether autoMode.environment trusts the right repos, buckets, and domains, how the allow, soft_deny, and hard_deny tiers resolve, and whether $defaults is kept across settings scopes.

Storybook MCP addon that lets Claude and other MCP clients inspect component documentation, generate stories, preview UI states, and run Storybook tests against a local Storybook project.

A CLAUDE.md rule set that turns Claude into a senior .NET reviewer aligned with current Microsoft guidance across ASP.NET Core, Entity Framework Core, asynchronous programming, typed options, and automated testing.

Claude Code statusline that uses GitHub pull request search qualifiers to show review-requested queue counts for maintainers.

Source-backed agent that reviews active Claude Code sessions and configuration for security gaps, cross-references the official security guidance, and produces a ranked remediation plan covering permissions, MCP trust, prompt injection, credential handling, and hook safety.

Slash command that reviews a pull request diff for security regressions: authentication and authorization gaps, injection surfaces, secret exposure, unsafe deserialization, and dependency risk introduced by the change.

PreToolUse hook that reviews proposed writes to MCP configuration files and blocks inline credential values, credential-bearing URLs, and broad filesystem roots before they are saved.

Source-backed Claude Code subagent that reviews MCP tool result sizes against output token budgets, flagging tools that exceed the warning and default limits and recommending pagination, filtering, MAX_MCP_OUTPUT_TOKENS tuning, and per-tool size annotations.

Source-backed agent that reviews the container isolation posture of a NanoClaw deployment, checking filesystem mounts, per-agent scoping, credential vault routing, messaging channel permissions, and scheduled tasks before agents run with real access.

PreToolUse hook that reviews proposed Bash commands for package, installer, and archive downloads, then blocks curl or wget download commands that do not include an adjacent checksum or signature verification step.

Source-backed agent that reviews Claude Code plugins for dependency and compatibility issues, checking the plugin.json manifest, bundled components, external binaries like LSP servers, versioning, and namespace conflicts, grounded in the official Claude Code plugin docs.

Source-backed agent that reviews Claude Code's sandboxed Bash configuration for safe boundaries, checking filesystem allow/deny paths, network allowlists, unsandboxed escape hatches, excluded commands, and credential read scope, grounded in the official Claude Code sandboxing docs.

Slash command that reviews the supply-chain risk of a project's dependencies using OpenSSF Scorecard health signals rather than CVE counts.

A Claude Code DevOps engineer persona grounded in GitHub Actions, Terraform, Docker, and Kubernetes. It writes and reviews CI/CD workflows, IaC, and deployment manifests using real tooling and documented commands.

Comprehensive system for ensuring code quality, security, and compliance before production deployment. Includes automated code reviews, complexity monitoring, backup strategies, and production-grade rules for professional development teams.

Source-backed rules for registry repositories that must keep contributor PRs focused on source files while generated indexes, feeds, downloads, search data, README output, and previews are rebuilt by trusted automation.
