Convert measurement systems, format dates/times/numbers/currency by locale, adapt address formats, and handle locale-specific sorting. Use when localizing technical content for regions. Activates on "localization", "date format", "measurement conversion", or "locale adaptation".

Write meaningful code comments that explain WHY rather than WHAT, focusing on business logic, non-obvious solutions, workarounds, and complex algorithms while keeping code self-documenting. Use this skill when adding comments to explain rationale, documenting complex business logic, explaining workarounds or temporary solutions, describing performance optimizations, writing function documentation (JSDoc, docstrings, XML docs), or reviewing code for appropriate commenting. Apply when working on any code file that contains logic requiring explanation, public API functions, complex algorithms, security-critical code, or architectural decisions. This skill ensures comments explain rationale not implementation (WHY not WHAT), self-documenting code through clear naming (refactor unclear code instead of commenting), concise and evergreen comments (no who/when dated comments - Git tracks this), links to external resources for context, proper function documentation format (JSDoc for TS/JS, docstrings for Python, XML d

Validate markdown documentation against meta-agentic best practices. Use when validating skills, commands, checking broken links, validating frontmatter, auditing documentation structure, or running compliance checks.

Work with MongoDB (document database, BSON documents, aggregation pipelines, Atlas cloud) and PostgreSQL (relational database, SQL queries, psql CLI, pgAdmin). Use when designing database schemas, writing queries and aggregations, optimizing indexes for performance, performing database migrations, configuring replication and sharding, implementing backup and restore strategies, managing database users and permissions, analyzing query performance, or administering production databases.

Use when user wants to add a new sensor to the Enviro+ monitoring system, or asks to monitor a new data point. Guides through importing libraries, initialization, reading sensor values, publishing to Adafruit IO and Home Assistant, updating documentation, testing, and rate limit verification.

Use this skill when you need to structure data in `srs/data` for the Next.js app

Manage hierarchical project plans in SQLite. Tree-based structure with phases and tasks. Multiple output formats (text, JSON, XML, markdown).

Guide users through structured feature specification creation from idea to complete spec. Use when user wants to create a feature specification, product requirements document (PRD), technical spec for a feature, or similar structured feature planning documentation. This workflow helps users efficiently gather context, explore the codebase, define requirements, draft technical approach, and save the result to JIRA or Confluence. Trigger when user mentions "create a spec", "spec out", "write a PRD", "feature specification", or similar feature planning tasks.

Detect document source type (Zoom, Slack, JIRA, Confluence, email, meeting notes) from content patterns. Use when processing raw documents during intake or when identifying document types.

Identifies, evaluates, and mitigates project and task-level risks during planning. Use when assessing technical risks, evaluating complexity, identifying blockers, planning contingencies, or determining project confidence levels.

Use when writing UnoCSS with presetOnmax workflow - covers attribute mode patterns, fluid spacing (f- prefix), scale-to-pixel (1px base), custom variants (hocus, reka-*, data-state), nimiq-css design system (nq-* utilities), and Reka UI integration. Apply when editing .vue files with UnoCSS attributes or configuring uno.config.ts.

DuckDB data lakehouse development with Dagster orchestration and Apache Iceberg integrationfor floe-platform. Use when: (1) Building data pipelines with DuckDB as compute engine,(2) Configuring dbt-duckdb with Polaris plugin, (3) Reading/writing Iceberg tables viaPolaris catalog, (4) Creating Dagster assets with DuckDB, (5) Designing catalog-firstlakehouse architecture, (6) Connecting to REST catalogs with inline credentials.

Load coding conventions and style guidelines when writing or reviewing code. Ensures consistency with project standards.

Manage project planning, documentation, and ticket coordination. Use this skill for: (1) Project planning and roadmap management, (2) Creating and coordinating tickets (T0000N), (3) Managing docs/ directory structure and CRUD operations, (4) Post-ticket completion tasks (export tests, update planning docs).

Comprehensive Meta Ads account auditing using Pipeboard Meta MCP and Stape MCP tools. Use when conducting performance audits, analyzing ad account data, evaluating tracking infrastructure (Pixel/CAPI/Stape), creating audit reports, assessing campaign performance, managing Stape containers, or generating architecture diagrams.

Helps refactor code for better structure, readability, and maintainability. Use when cleaning up code, improving design, or removing technical debt.

Create comprehensive PAI skills from tool/CLI/API documentation. Analyzes docs (markdown or URLs via crawl4ai), deduces workflows, generates helper scripts/templates/guardrails, and builds complete skill packages. USE WHEN user says 'create skill from docs', 'build skill for [tool]', 'turn documentation into skill', or provides documentation to transform into a skill.

Documentation synchronization using Mem0 for tracking relationships between specs, architecture, ADRs, and roadmap

Use when web.run fails to parse a webpage and you need raw Markdown via Crawl4AI.

Use PROACTIVELY when reviewing CLAUDE.md configurations, onboarding new projects, or before committing memory file changes. Validates against official Anthropic documentation, community best practices, and LLM context optimization research. Detects security violations, anti-patterns, and compliance issues. Not for runtime behavior testing or imported file validation.
