Internationalization (i18n) and localization (l10n) specialist. Hardcoded string extraction to t() functions, Intl API integration for date/currency/number formatting, translation key structure management, and RTL layout support. Use when multi-language support or i18n setup is needed.
OWASP ZAP/Burp Suite/Nuclei integration, penetration test planning, DAST execution, and vulnerability scanning. Use when dynamic security testing, penetration testing, or runtime vulnerability validation is needed. Complements Sentinel static analysis.
UX writing specialist for user-facing text. Handles microcopy, error messages, voice and tone design, onboarding copy, and accessibility text. Use when UX writing or content strategy is needed.
KPI definition, tracking event design, and dashboard specification. North Star Metric, funnel analysis, and cohort analysis design. GA4/Amplitude/Mixpanel/PostHog integration. Use when metrics foundation is needed.
Edge-case test addition, flaky test repair, and coverage improvement. Use when test gaps need filling, reliability needs raising, or regression tests need adding. Multi-language support (JS/TS, Python, Go, Rust, Java).
Priority quantification agent. Scores and orders competing items using ICE/RICE/WSJF/MoSCoW/Cost of Delay/Kano frameworks. Does not write code.
User research specialist. Designs interview guides, usability test plans, qualitative data analysis, persona creation, and journey mapping. Complements Echo's UI validation. Use when user research design or analysis is needed.
Git history investigation, regression root cause analysis, and code archaeology specialist. Time-travels through commit history to uncover truth. Use when git history investigation or regression analysis is needed.
Interactive brainstorming partner that deepens ideas through iterative dialogue using four thinking modes (Expand/Propose/Evaluate/Subtract). Use when bouncing ideas, exploring possibilities, or refining concepts. Does not write code. Don't use for decisions (Magi), feature specs (Spark), or single-shot reframing (Flux).
Infrastructure provisioning specialist for cloud IaC (Terraform/OpenTofu/CloudFormation/Pulumi) and local development environments (Docker Compose/dev setup/env vars). Use when IaC design, environment setup, or multi-cloud provisioning is needed.
Database schema design, migration planning, and ER diagram specialist. Handles normalization, index strategies, and relation definitions. Use when DB schema design is needed.
Search engine and vector DB design specialist. Use when full-text search, vector search, or hybrid search design, index optimization, or RAG retrieval layer implementation is needed.
Storybook story creation, catalog management, and Visual Regression integration. Handles UI component documentation, visual testing, and CSF 3.0/Factories format story creation. Supports Storybook 10 (ESM-only) and React Cosmos. Use when component documentation or visual testing is needed.
Load testing, contract testing, chaos engineering, mutation testing, and resilience verification specialist. Use when system limit verification, non-functional testing, or reliability validation is needed.
Proposes new features leveraging existing data/logic as Markdown specifications. Use when brainstorming new features, product planning, or feature proposals are needed. Does not write code.
Ghost hunter for 'invisible' concurrency, async, and resource management issues. Detects, analyzes, and reports Race Conditions, Memory Leaks, Resource Leaks, and Deadlocks. Does not write code. Delegates fixes to Builder.
Build-first product delivery engine. Delivers working code fastest via minimum agent chains scoped to the task. S/M scopes skip planning and build immediately.
Detection Engineering agent. Designs Sigma/YARA rules, maps detection coverage, designs threat hunting hypotheses, executes Purple Team Blue side, and integrates Detection-as-Code CI/CD. Use when defensive security verification is needed.
YAGNI verification, scope cutting, pruning, and complexity reduction proposals. A 'subtraction' agent that questions the justification for every code, feature, process, document, design, spec, dependency, and config. Does not write code.
E2E testing specialist. Handles Playwright/Cypress/WebdriverIO configuration, Page Object design, auth flows, parallel execution, visual regression, a11y testing, and CI integration. Validates entire user journeys. Use when E2E test creation is needed.
Tech blog/article series authoring for note/Zenn/Qiita/dev.to. Not for specs (Scribe) or microcopy (Prose).

Use when generating images with Alibaba Cloud Bailian API, especially for Chinese text rendering or photorealistic images
Discover and execute specialized skills from a curated marketplace catalog on GitHub, fetched on-demand and run ephemerally (no permanent installation). The catalog covers a broad and growing range — document generation (PDF/Word/Excel/PowerPoint), visual design, presentations, web app testing, animated GIFs, dev tooling (MCP scaffolding, frontend components), creative outputs (algorithmic art), technical documentation lookup (library/API/framework references), and more. Consult this skill whenever the user asks for a capability that could plausibly be covered by a community skill — the catalog is the source of truth, not this description.
Fetch up-to-date library, framework, and SDK documentation via Context7's search and docs endpoints. Use when the user asks about a library/API (React, Next.js, Prisma, Supabase, Tailwind, Django, Vue, etc.) and you need current docs, not Claude's training-time knowledge. Skip this skill for generic programming questions that don't require library-specific docs.
Manage n8n workflow automation via its REST API — list/get/create/update workflows, trigger executions, inspect run history, manage credentials and nodes. Works with self-hosted n8n and n8n Cloud. Use when the user wants to interact with their n8n instance programmatically without the n8n MCP installed.
Helps detection engineers identify coverage blind spots in system command execution detection rules, evaluate bypass risks, and reduce false negatives. Strictly limited to system command execution rules; not applicable to browser credential theft or abnormal process creation without command semantics.
