Development

Transforms project briefs into testable specifications with user stories and acceptance criteria. Use after brainstorming, before planning.

Transform specifications into structured implementation plans with architecture design and dependency-ordered task breakdown. Use when: converting specs to plans, designing architecture, breaking down tasks, estimating effort. Do not use when: no specification exists yet or still brainstorming approaches.

Scaffolds new projects with git, CI/CD workflows, pre-commit hooks, and build config. Use when starting a new Python, Rust, or TypeScript project from scratch.

Execute implementation plans systematically with checkpoint validation, progress tracking, and continuous quality gates. Use when: implementing tasks, executing plans, tracking progress, validating checkpoints. Do not use when: no implementation plan exists or still in planning phase.

Configure three-layer pre-commit quality system with linting, type checking, and testing hooks. Use when: setting up quality gates, configuring pre-commit, establishing code quality standards. Do not use when: pre-commit already configured optimally.

Generates Makefiles with testing, linting, formatting, and automation targets. Use when starting a project or standardizing build automation.

Architecture-aware project initialization combining online research with archetype selection. project initialization, new project, architecture decision, project setup, which architecture, choose architecture, project architecture Use when: initializing a new project and need to select an appropriate architecture based on project type, team size, domain complexity, and current best practices DO NOT use when: architecture is already decided - use project-init instead. DO NOT use when: explo...

Deep explanation of complex code, files, or concepts. Routes to expert agents, uses structural search, generates mermaid diagrams. Triggers on: explain, deep dive, how does X work, architecture, data flow.

Surface expert frameworks. Use when creating or evaluating skills, hooks, or agents.

Patterns for building production-quality CLI tools with predictable behavior, parseable output, and agentic workflows. Triggers: cli tool, command line tool, build cli, cli patterns, agentic cli, cli design, typer cli, click cli.

Atom of Thoughts (AoT) reasoning - decompose complex problems into atomic units with confidence tracking and backtracking. For genuinely complex reasoning, not everyday questions. Triggers on: atomise, complex reasoning, decompose problem, structured thinking, verify hypothesis.

**Version:** 1.0.0 **Purpose:** Visual regression testing with screenshot capture, comparison, and baseline management **Integration:** Playwright + SQLite + Redis coordination ---

End-to-end MegaETH development playbook (Feb 2026). Covers wallet operations, token swaps (Kyber Network), eth_sendRawTransactionSync (EIP-7966) for instant receipts, JSON-RPC batching, real-time mini-block subscriptions, storage-aware contract patterns (Solady RedBlackTreeLib), MegaEVM gas model, WebSocket keepalive, bridging from Ethereum, and debugging with mega-evme. Use when building on MegaETH, managing wallets, sending transactions, or deploying contracts.

Provides Zig patterns for type-first development with tagged unions, explicit error sets, comptime validation, and memory management. Must use when reading or writing Zig files.

Classify tasks, initialize structured configs with scope boundaries, decompose complex tasks

Provides TypeScript patterns for type-first development, making illegal states unrepresentable, exhaustive handling, and runtime validation. Must use when reading or writing TypeScript/JavaScript files.

Provides Tamagui patterns for config v4, compiler optimization, styled context, and cross-platform styling. Must use when working with Tamagui projects (tamagui.config.ts, @tamagui imports).

Provides React patterns for hooks, effects, refs, and component design. Covers escape hatches, anti-patterns, and correct effect usage. Must use when reading or writing React components (.tsx, .jsx files with React imports).

Generate detailed sprint plans with focused context injection, ensuring clear scope boundaries and dependencies.

**Status:** Production Ready | **Category:** Provider Integration | **Complexity:** Low

Hand off a task to Codex CLI for autonomous execution. Use when a task would benefit from a capable subagent to implement, fix, investigate, or review code. Codex has full codebase access and can make changes.

Reduce and focus project scope when agents are consistently stuck or unable to make progress. 1. Identify critical deliverables 2. Defer non-essential components 3. Create minimal, achievable goals 4. Provide focused context injection - Analyze unfinished deliverables - Select 1-2 most critical items - Generate focused, achievable context - Defer remaining deliverables to future iterations ```bash ./simplify-scope.sh \ --original-deliverables "file1.ts,file2.ts,file3.ts"

Yellow Network and Nitrolite (ERC-7824) development best practices for building state channel applications. Use when building apps with Yellow SDK, implementing state channels, connecting to ClearNodes, managing off-chain transactions, or working with application sessions.

Centralized file locking and atomic write operations for bash scripts. **Part of Task 4.2: Centralized File Locking & Atomic Operations**
