Cross-agent personal network manager skills for Rarefriend — six Agent Skills for contacts, notes, LinkedIn, Google Calendar/Contacts, and Microsoft Outlook email and calendar. Requires Rarefriend MCP.
Microsoft .NET team skill marketplace for AI coding agents working on .NET, C#, ASP.NET Core, Blazor, MAUI, diagnostics, MSBuild, NuGet, upgrades, tests, AI workflows, RAG pipelines, and C# MCP servers.
Addy Osmani's production-grade Agent Skills pack for AI coding agents, with lifecycle slash commands, engineering workflow skills, review personas, quality gates, and cross-agent setup guidance for Claude Code, Cursor, Gemini CLI, Antigravity CLI, OpenCode, GitHub Copilot, and other agents.
Anthropic's public Agent Skills repository for Claude, with example skills, document skills, the Agent Skills specification pointer, a template skill, Claude Code plugin installation, Claude.ai usage guidance, and Claude API skill creation references.
✓Skills call Rarefriend MCP with OAuth credentials; store client ID/secret in env or client config, never in chat logs or committed files.
Contact, calendar, and email tools mutate user CRM data; confirm destructive actions (delete, bulk update) before executing.
LinkedIn and Google/Microsoft integrations depend on connected accounts; verify workspace scope before sharing output externally.
✓.NET build, test, upgrade, package, template, publish, and migration tasks can modify project files, lock files, generated code, packages, app settings, and deployment artifacts.
Diagnostics skills may suggest collecting traces, dumps, counters, crash data, MSBuild binlogs, or performance profiles; collect those artifacts only with explicit approval and storage controls.
MCP server skills can expose local code, files, APIs, credentials, or production services as callable tools; review tool descriptions, parameter validation, authorization, and transport choice before connecting clients.
NuGet and publish workflows can push packages or artifacts to public or private feeds; verify package IDs, versions, API keys, feed targets, and release policy before publishing.
Upgrade and modernization guidance should be verified against each application's framework support window, deployment target, package compatibility, and rollback plan.
✓The slash commands are designed to guide real coding, testing, reviewing, committing, and shipping work; keep edits, commits, pushes, CI changes, and deploys behind the host's normal approval controls.
`/build auto` is explicitly intended to generate a plan and implement multiple tasks in one approved pass. Use it on bounded specs, review the generated plan first, and stop on test failures or risky changes.
The skills encode durable engineering workflows, not guaranteed-current framework APIs. Follow the source-driven-development guidance and verify current documentation before applying generated code.
Security, CI/CD, observability, migration, and launch skills can touch production-sensitive systems. Require dry-run plans, rollback notes, and environment scoping before approving operational commands.
Review personas and quality gates are useful second opinions, but they do not replace maintainer review, domain-specific tests, threat modeling, or release sign-off.
✓The repository is explicitly presented as demonstration and educational material; behavior available in Claude products can differ from repository examples.
Document skills can read, transform, and create files such as PDFs, Word documents, PowerPoint decks, and spreadsheets, so review generated artifacts before sharing or publishing them.
The MCP builder skill guides agents through creating MCP servers and evaluations; generated servers still need security review, least-privilege tool design, authentication review, and transport testing.
The skill creator workflow can generate instructions, scripts, references, and assets; review all generated resources before installing them into an agent host.
Privacy notes
✓MCP calls send contact names, emails, notes, calendar events, and email metadata to Rarefriend servers for the authenticated user only.
Do not paste OAuth client secrets, refresh tokens, or full contact exports into public issues, PRs, or shared transcripts.
Per-skill setup in `skills/<name>/references/SETUP.md` describes required scopes and data access for each integration.
✓.NET repositories may contain connection strings, appsettings secrets, user secrets, certificates, environment variables, telemetry keys, logs, traces, dumps, package credentials, and production data.
MSBuild binlogs, crash dumps, profiler output, and test artifacts can contain source paths, dependency graphs, request data, exception payloads, configuration values, and environment details.
MCP servers created with these skills may forward prompts and tool inputs to local processes, HTTP services, databases, cloud APIs, or third-party model providers depending on the implementation.
Keep private NuGet credentials, signing keys, deployment secrets, customer data, dumps, and proprietary source out of public prompts, issues, pull requests, and shared artifacts.
✓Using the pack with an AI agent can expose repository code, product requirements, architecture notes, tests, CI logs, deployment settings, incidents, security findings, and launch plans to the configured model provider.
Do not paste secrets, customer data, private incident records, production credentials, unpublished roadmap details, or proprietary compliance material into public prompts, issues, screenshots, or PR bodies.
Agent personas and review workflows may ask for browser traces, performance data, logs, build output, dependency lists, and environment details; redact tokens and private URLs before sharing artifacts.
✓Skill usage can expose documents, spreadsheets, slide decks, prompts, company workflows, brand guidelines, MCP designs, API details, and generated artifacts to Claude or the configured model/runtime.
Do not upload or commit customer documents, regulated data, private brand assets, secrets, credentials, or unreleased business plans unless the environment and account policy allow that data.
When creating custom skills, check bundled scripts, references, and assets for private data before sharing a repository, plugin, or ZIP archive.
