Detect and capture technical preferences, naming conventions, and architectural practices from user messages into Packmind standards. Trigger when user prescribes HOW to code through direct statements (e.g., "Use snake_case for columns", "Always use async/await") or suggestive patterns like questions ("Could we use X instead?"), code review feedback ("This would be clearer with X"), and comparative statements ("Use X instead of Y"). Does NOT trigger for feature requests, bug reports, or general implementation tasks without coding preferences.

Fetch and digest news from Google News RSS feeds and Google Alerts by topic. Extracts full article content, images, and videos. Scans configured topics, deduplicates stories, and produces a rich markdown digest with article summaries. Use when the user wants a news summary, news digest, Google News scan, or says things like "what's in the news", "news about X", "news digest", "scan my news feeds", or "/news-digest".

Reference for COBOL COMP-3 (packed decimal / BCD) numeric storage -- layout on disk, declaring it in the FD, and pitfalls when carrying the decoded value through working storage and into later arithmetic. Useful when an input record holds a balance, rate, or carry-forward as packed decimal rather than a printable digit string.

Git expert combining atomic commits, rebase/squash, and history search (blame, bisect, log -S). Use for any git operations requiring structured commit strategies, history rewriting, or code archaeology. Triggers: 'commit', 'rebase', 'squash', 'who wrote', 'when was X added', 'find the commit that'.

Godot workflow for SpriteCook assets. Use when the user wants to turn SpriteCook spritesheet PNGs, animation assets, or character animation runs into Godot SpriteFrames resources and AnimatedSprite2D/AnimatedSprite3D animation nodes. Covers both manual spritesheet-to-Godot setup and the optional SpriteCook MCP Godot export endpoint.

Load when authoring, writing, or designing a Kotlin Toolchain local plugin to extend the declarative build with code generation, build-time processing, custom verification, or packaging that module.yaml cannot express, or when referencing @TaskAction, @Configurable, plugin.yaml, or jvm/amper-plugin. Skip for porting an existing Gradle plugin.

Rules and guidelines for working with Spring Data JDBC in the project. ALWAYS use this skill when adding, removing, or modifying Spring Data JDBC entities (@Table from org.springframework.data.relational.core.mapping), aggregates, AggregateReference links, embedded objects, @MappedCollection associations, or Spring Data JDBC repositories (CrudRepository / ListCrudRepository). Trigger on any request that touches @Table, @Column, @MappedCollection, @Embedded annotations from spring-data-relational, AggregateReference fields, @PersistenceCreator constructors, or @Query methods on JDBC repositories. Do NOT use for JPA (jakarta.persistence) entities — use the spring-data-jpa skill instead.

Create Roslyn-based analyzers and code-fix providers for detecting Web Forms migration patterns. Covers DiagnosticAnalyzer architecture, diagnostic ID conventions (BWFC001–BWFC099), CodeFixProvider authoring, testing with CSharpAnalyzerTest/CSharpCodeFixTest, and the analyzer release tracking files. Use when adding a new migration rule, creating a code-fix suggestion, or debugging analyzer behavior.

Parallel read-only multi-agent review of a current git diff or explicit file scope to find behavioral regressions, security or privacy risks, performance or reliability issues, and contract or test coverage gaps. Use when the user asks for a review swarm, parallel review, diff review, regression review, security review, or wants high-signal issues plus a prioritized fix path without editing files.

Product manager for Ralph autonomous builds. Manages beads through interactive conversation. No code editing, only bead management. Use when managing work items for Ralph, resolving blocked beads, creating new development tasks, or checking recent Ralph activity.

Convert Figma or Pencil designs into production-ready frontend code using Feature-Sliced Design and Tailwind CSS v4. Use when translating designs into code, extracting tokens, mapping UI to FSD layers (shared / entities / features / widgets / pages / app-shell / app), enforcing Server vs Client boundaries when applicable, or validating design-to-code fidelity.

DEPRECATED - this skill is unmaintained. Use the official Angular skills at https://github.com/angular/skills instead. Implement dependency injection in Angular v20+ using inject(), injection tokens, and provider configuration. Use for service architecture, providing dependencies at different levels, creating injectable tokens, and managing singleton vs scoped services. Triggers on service creation, configuring providers, using injection tokens, or understanding DI hierarchy.

DEPRECATED - this skill is unmaintained. Use the official Angular skills at https://github.com/angular/skills instead. Create modern Angular standalone components following v20+ best practices. Use for building UI components with signal-based inputs/outputs, OnPush change detection, host bindings, content projection, and lifecycle hooks. Triggers on component creation, refactoring class-based inputs to signals, adding host bindings, or implementing accessible interactive components.

Use when updating this codex-app Linux port from the latest upstream Codex Mac DMG, preserving local Linux patches, installing the refreshed desktop app, and publishing the tag-driven Linux release artifacts.

Naval Ravikant的思维操作系统。基于著作、播客、推文、决策记录和外部批评的深度调研， 提炼5个核心心智模型、8条决策启发式和完整的表达DNA。 激活后沉浸式扮演Naval，直接以「我」的视角回应问题。 当用户提到「用Naval的视角」「Naval会怎么看」「纳瓦尔模式」「Naval perspective」「切换到Naval」时使用。 即使用户只是说「这份工作有杠杆吗」「什么是specific knowledge」「什么是真正的财富」「欲望太多怎么办」「无需许可的路径」也可触发。 不要在用户只是问「我该怎么选择」「帮我想清楚」等一般性决策问题时触发——只在涉及杠杆/特定知识/欲望管理/财富定义等Naval核心概念时激活。

MrBeast（Jimmy Donaldson）的内容创造操作系统。基于泄露的36页内部培训手册、 6个深度播客、决策记录和外部批评的深度调研，提炼6个核心心智模型、8条决策启发式、 完整的标题/缩略图/Hook/节奏公式，和4个可运行的内容分析脚本。 激活后沉浸式扮演MrBeast，直接以「我」的视角给出内容创作建议。 当用户提到「用MrBeast的视角」「MrBeast会怎么做」「Beast模式」「mrbeast perspective」时使用。 即使用户只是说「视频CTR怎么提升」「标题不够吸引人」「retention曲线怎么优化」「缩略图要改吗」也应触发。 不要在用户只是说「内容创作建议」「怎么做内容」等一般性问题时触发——只在涉及视频优化、标题/缩略图/Hook/留存率等YouTube方法论时激活。

How to create and use AccountAddress in @aptos-labs/ts-sdk. Covers address format (AIP-40), from/fromString/fromStrict, special addresses, LONG vs SHORT form, and derived addresses (object, resource, token, user-derived).

Write conventional commit messages with type, scope, and subject when the user wants to commit changes or save work.

This skill should be used when users want to scrape multiple websites (Firecrawl, Parallel, or hybrid), extract brand guideline signals (including CSS variables + computed styles via browser probing), generate per-site prompt packs, and blend sources into a composite brand direction with exactly three outputs: brand_guidelines.md, prompt_library.json, design_tokens.json.

Route broad code-quality reviews and refactors across branching, duplication, mixed responsibilities, and hidden concepts. Use for broad requests to clean up, simplify, refactor, or identify code smells; use the matching specialist directly when the request names one concern.
