Apply when creating or editing prompts targeting GPT-5.4. Covers output contracts, scope discipline, reasoning_effort tuning, long-context handling, ambiguity management, tool persistence, completeness and verification contracts, structured extraction, research mode with citation discipline, personality controls, coding autonomy, compaction awareness, and migration from older GPT models.

Improve unclear UX copy, error messages, microcopy, labels, and instructions to make interfaces easier to understand. Use when the user mentions confusing text, unclear labels, bad error messages, hard-to-follow instructions, or wanting better UX writing.
Audit and refactor CSS to comply with Game Loopers design system and BEM methodology
Autonomous end-to-end execution skill. Use when the user gives a broad directive (improve, audit, fix, ship, polish) that should run from audit through deploy without check-ins. This skill codifies the loop-until-live pattern and the stop conditions.
Ensures new Rails views, layouts, and page-level UI in rails-pokedex are designed in Google Stitch and retrieved via MCP before coding. Use when creating ERB templates, layouts, partials, styling overhauls, or any new user-facing page; when refactoring views; or when the user mentions Stitch, UI de página, telas, or frontend Rails.
Research and improve Claude skills with current best practices. Triggers on requests to improve skills, update skills, research best practices for skills, enhance skill quality, or modernize existing skills.
Convert behavior misses raised in chat into durable process updates by editing the right rule, skill, or workflow file, with explicit handling for GitHub release quality.
>
Maintain a development log (DEVLOG.md) at the project root. Use at the START and END of every coding session, after implementing features, fixing bugs, refactoring code, or making any meaningful code changes. Automatically triggered for all development tasks.
Sync .env from 1Password using env_var_mappings.

Create or improve a skill by using the system skill when available and the legacy local bundle as fallback
Symbol-level refactoring with automatic reference updates using Serena MCP
Map the repository before major refactors. Explain architecture, ownership, data flow, control flow, and blast radius in plain English.
Fast semantic code navigation via LSP. Load FIRST before ANY code task - even 'simple' ones. Trigger scenarios: (1) fixing lint/type/pyright/mypy warnings or errors, (2) fixing reportAny/reportUnknownType/Any type errors, (3) adding type annotations, (4) refactoring or modifying code, (5) finding where a function/class/symbol is defined, (6) finding where a symbol is used/referenced/imported, (7) understanding what a function calls or what calls it, (8) exploring unfamiliar code or understanding architecture, (9) renaming symbols across codebase, (10) finding interface/protocol implementations, (11) ANY task where you'd use ripgrep to find code or read-file to view a function. Use `leta show SYMBOL` instead of read-file, `leta refs SYMBOL` instead of ripgrep for usages, `leta grep PATTERN` instead of ripgrep for definitions, `leta files` instead of list-directory.
Self-improving agent architecture using ChromaDB for continuous learning, self-evaluation, and improvement storage. Agents maintain separate memory collections for learned patterns, performance metrics, and self-assessments without modifying their static .md configuration.
Manages deprecation and migration. Use when removing old systems, APIs, or features. Use when migrating users from one implementation to another. Use when deciding whether to maintain or sunset existing code.
Enforce British English using Oxford spelling conventions, permit outwith and caveat where appropriate, and use the Oxford comma only when it improves clarity.
Database operations for Supabase: query/write/migration/logs/type generation. Triggers: query/statistics/export/insert/update/delete/fix/backfill/migrate/logs/alerts/type generation. Does not trigger for: pure architecture discussion or code planning. Write operations require confirmation; UPDATE/DELETE without WHERE is refused. MCP is optional — works with CLI/Console too.
Provides an incremental adoption strategy to migrate native iOS or Android apps to React Native or Expo using @callstack/react-native-brownfield for initial setup. Use when planning migration steps, packaging XCFramework/AAR artifacts, and integrating them into host apps.
Global evolution system for ship-faster skills. Uses hooks to capture context, failures, and session summaries, then generates patch suggestions (no auto edits) via skill-improver. Use when you want the skills to self-improve safely and continuously.
Extract a shareable runnable template under templates/NNN-slug/ from a real project: copy + de-brand + remove secrets + add env examples + docs, with minimal refactors. Use when you have a working project and want to turn it into a template.
Workflow orchestration, sub-agent architecture, and task management patterns
Applies prompt repetition to improve accuracy for non-reasoning LLMs
Execute database operations via Supabase MCP (query/write/migration/logs/type generation). Triggers: query/statistics/export/insert/update/delete/fix/backfill/migrate/logs/alerts/type generation. Does not trigger for: pure architecture discussion or code planning. Write operations require confirmation; UPDATE/DELETE without WHERE is refused.

Use when the user asks to run Codex CLI (codex exec, codex resume) or references OpenAI Codex for code analysis, refactoring, or automated editing

Safe refactoring workflow and common patterns. Invoke when extracting methods, renaming, moving code, or addressing code smells.
Identify, categorize, and prioritize technical debt across six dimensions. Generates remediation plans with effort estimates. Offered by /draft:new-track for refactor tracks.
