agent-skills

Pressure-test an assumption, architecture decision, estimate, or inherited constraint. Use when the user asks to challenge a belief, play devil's advocate, test reasoning, or find a simpler alternative.

Explain a code location, component, command, or user-facing system flow. Use when the user asks what code does, why it exists, how a feature works, or wants a trace of entry points, branches, dependencies, and side effects.

Prepare difficult technical or delivery news for a client, stakeholder, or team. Use for delays, incidents, security findings, cost changes, failed approaches, or other conversations where clarity and trust matter.

Plan and work through project, client, vendor, or team offboarding. Use for handovers, access removal, ownership transfer, documentation, credential rotation, data cleanup, and knowledge-transfer checklists.

Discover how a codebase already handles a concern before extending it. Use when asked how the repository does something, where a pattern lives, whether implementations are consistent, or what convention new work should follow.

Help the user think through a confusing problem or decision by asking focused questions and reflecting their reasoning. Use when they want to think out loud, untangle a problem, or find the question beneath the question.

Project-aware router for Ruby and Rails development. Use for gems, Rails, RSpec, Minitest, Cucumber, SimpleCov, RuboCop, RubyCritic, PostgreSQL, Active Record, debugging, reviews, performance, security, i18n, Sorbet, RBS, Ruby LSP, or Ruby runtime and tooling work.

Break a feature, epic, migration, or capability into independently valuable and verifiable delivery slices. Use when work is too large, vague, layered, risky, or needs sequencing around user value and learning.

Conduct an opt-in Socratic code review or refactoring conversation. Use when the user explicitly wants pairing through questions instead of an immediate findings report.

Draft a clear standup, end-of-day update, weekly update, or client progress note. Use when summarizing completed work, next steps, blockers, risks, decisions, and support needed for a team or stakeholder audience.

Use an opt-in, project-aware test-driven development loop for a feature, defect, or behavior change. Detects the repository's test framework and commands instead of assuming Rails, RSpec, or a direct host executable.

Build, migrate, maintain, and test Chef Infra cookbooks using modern custom resource patterns for the sous-chefs organization. Use when: building a new Chef cookbook with custom resources, migrating legacy library-based resources to modern resources/, fixing CI failures in a sous-chefs cookbook, adding ChefSpec or InSpec tests, restructuring cookbook directories, writing resource documentation, converting sysvinit/upstart to systemd, or when the user mentions "custom resource", "chef resource", "sous-chefs cookbook" or "chef cookbook".

Fish shell scripting reference and enforcement. Activate whenever executing shell commands, writing shell scripts, using run_command, or any shell interaction in the user's environment. Trigger on: any shell command, heredoc, string manipulation, variable assignment, loop, conditional, arithmetic, pipe, or script writing.

Synchronizes bank transactions from FreeAgent with invoices found in Gmail, uploads them to Paperless-ngx, and attaches them back to FreeAgent. Use this skill for weekly accounting maintenance or when the user asks to "sync invoices" or "connect FreeAgent and Paperless".

Send, search, and organize Gmail messages, drafts, and labels. Read full threads and get shareable Google Groups permalinks. Use when asked to compose an email, reply to mail, forward a message, search inbox, manage attachments, organize Gmail, read a thread, or find a Google Groups discussion link.

Retrospective on recent sessions - analyze patterns, improve skills/agents, capture learnings

Maintain translation files and keep locale trees in sync when UI copy changes, locale YAML files change, or new typography or design-system components introduce user-facing text. Use this skill for Rails i18n work, locale drift fixes, missing translation keys, and translation updates across config/locales.

Professional UI design guidance grounded in cognitive psychology, information theory, and interaction design. Use when designing, reviewing, or refining interfaces that need clear hierarchy, strong affordances, useful feedback, and low visual noise.

Optimize Go code for security, speed, memory use, and operational reliability. Use when working on Go performance tuning, benchmark-driven optimization, pprof analysis, allocation reduction, concurrency safety, request signing, crypto, input validation, dependency risk, or when the user asks to make Go code faster or safer.

Modernize codebases by checking EOL runtimes/platforms and upgrading dependencies with minimal context. Use for "modernize", "upgrade dependencies", "update versions", "check EOL", or ecosystem-specific updates for npm/Node, Ruby gems, Chef cookbooks, and Rust crates. For other ecosystems, ask which technology-specific guidance to use before loading more.

Expert guidance for building professional, responsive, and beautiful Terminal User Interfaces (TUIs) in Rust (Ratatui) and Ruby (TTY, cli-ui). Covers architectural patterns (Conductor/Model/App), async client reuse, parallelisation, secure authentication, and modern visual aesthetics. Use when building, refactoring, or styling TUI applications in any language.

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Interactive storyboard creation for exploring narrative arcs, user journeys, and UI flows. Supports "Narrative" (Product Manager style) and "UI Flow" (Mock-Audit style) modes. Use when you need to visualize ideas, define UI elements, or map emotional journeys before implementation.

Design interfaces following Google's Material Design system, the unified visual language bridging digital and physical worlds. Emphasizes bold graphic design, intentional motion, adaptive layouts, and the material metaphor. Use when building modern, accessible, delightful user interfaces across platforms.

Expert Site Reliability Engineer (SRE) specialized in deep-dive investigation of firing infrastructure alerts. Use this agent whenever Alertmanager or Grafana alerts are active and you need a comprehensive root-cause analysis. It should be used to investigate firing alerts by correlating Prometheus metrics and Loki logs, detecting error patterns, analyzing slow requests, and inspecting Kubernetes resource states to provide actionable remediation steps.

Automates the process of summarizing changes into a concise conventional commit and creating a GitHub Pull Request. Always uses a feature branch to ensure PR creation.

Search documents in Paperless-ngx via REST API. Full-text search, tag/correspondent filtering, and direct links to documents.
