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.

Use this skill for PR preparation. Use when preparing PRs for submission, running quality gates, drafting PR descriptions and templates. Do not use when reviewing existing PRs - use pr-review instead. DO NOT use when: just generating commit messages - use commit-messages.

Guidelines from the NASA Power of 10 rules for writing robust, verifiable code. Adapted for general software development with context-appropriate rigor. Use when writing critical code paths, reviewing for robustness, improving code quality. Do not use as rigid requirements for all code - match rigor to consequence.

Process external resources into actionable knowledge with evaluation, storage, and application decisions. knowledge intake, article evaluation, paper review, external resource Use when: user shares links to articles, papers, or external resources DO NOT use when: searching existing knowledge - use knowledge-locator.

Functional Core, Imperative Shell: isolate deterministic logic from side effects for testability. Triggers: functional-core, imperative-shell, pure functions, side-effects, testability Use when: business logic is entangled with I/O or tests are brittle DO NOT use when: simple scripting without complex logic, or performance-critical hot paths where immutability overhead matters.

NEVER escalate without investigation first. This is the Iron Law. Use when evaluating whether to escalate models, facing genuine complexity requiring deeper reasoning, novel patterns with no existing solutions, high-stakes decisions requiring capability investment. Do not use when thrashing without investigation - investigate root cause first. DO NOT use when: time pressure alone - urgency doesn't change task complexity. DO NOT use when: "just to be safe" - assess actual complexity instead.

Consult this skill for Python performance profiling and optimization. Use when debugging slow code, identifying bottlenecks, optimizing memory, benchmarking performance, production profiling. Do not use when async concurrency - use python-async instead. DO NOT use when: CPU/GPU system monitoring - use conservation:cpu-gpu-performance.

Consult this skill when searching or navigating stored knowledge. Use when searching for stored knowledge, cross-referencing concepts, discovering connections, retrieving from palaces, finding past PR decisions. Do not use when creating new palace structures - use memory-palace-architect. DO NOT use when: processing new external resources - use knowledge-intake.

Authentication patterns for external services: API keys, OAuth, token management, verification. authentication, API keys, OAuth, token management, credentials.

Evaluate and improve Claude skill quality through auditing. Use when reviewing skill quality, preparing skills for production, or auditing existing skills. Do not use when creating new skills (use modular-skills) or writing prose (use writing-clearly-and-concisely). Use this skill before shipping any skill to production.

Retrospective workflow evaluation and improvement of skills, agents, commands, and hooks. workflow improvement, retrospective, workflow efficiency Use when: workflow felt slow, confusing, or needs optimization DO NOT use when: simple one-off fixes - use fix-pr or do-issue instead.

Outputs markdown digests and CSV exports for GitHub issues and PRs. Use when creating status reports, weekly updates, stakeholder briefings, generating GitHub comment digests, tracking initiative health. Do not use when release gates/readiness - use release-health-gates. DO NOT use when: project planning - use spec-kit:speckit-orchestrator.

Consult this skill when designing client-server systems or API architectures. Use when traditional web/mobile applications with centralized services, clear separation between client and server responsibilities needed. Do not use when selecting from multiple paradigms - use architecture-paradigms first. DO NOT use when: peer-to-peer dominates - consider dedicated P2P patterns.

Generate or remediate documentation with human-quality writing and style adherence. Use when creating new documentation, rewriting AI-generated content, or applying style profiles. Do not use for slop detection only (use slop-detector) or learning styles (use style-learner).

Interactive selector and router for architecture paradigms. Use when selecting architecture patterns for new systems, comparing paradigm trade-offs, creating architecture decision records, evaluating architecture fit for team size and domain complexity, planning implementation roadmaps. Do not use when implementing a specific known paradigm - use the specific architecture-paradigm-* skill (hexagonal, layered, microservices, etc.) instead. reviewing existing architecture - use architecture-review instead. Use this skill BEFORE making architecture decisions. Check even if unsure about needs.

Cross-plugin testing quality metrics and standards. Referenced by pensive:test-review and parseltongue:python-testing. testing standards, quality metrics, coverage thresholds, anti-patterns Use when: test quality evaluation, coverage thresholds, quality standards DO NOT use when: simple scripts without quality requirements.

Transform project briefs into testable specifications with acceptance criteria. Use for requirements translation, spec creation, pre-implementation. Skip if spec exists or still exploring.

Consult this skill for session-scoped temporary knowledge structures. Use when working on complex multi-step projects, preserving context across interruptions, tracking session-specific state. Do not use when permanent knowledge structures needed - use memory-palace-architect. DO NOT use when: searching existing knowledge - use knowledge-locator.

Consult this skill when designing permanent memory palace structures. Use when creating new memory palace structures, organizing complex domains, designing spatial layouts for knowledge retention. Do not use when quick knowledge search - use knowledge-locator instead. DO NOT use when: session-specific context - use session-palace-builder.

Consult this skill when cultivating and maintaining digital gardens. Use when managing note collections, creating link structures, maintaining knowledge bases, tending garden health and growth. Do not use when creating memory palace structures - use memory-palace-architect. DO NOT use when: evaluating new knowledge - use knowledge-intake.
