Public Skills
user-story
by mhylle
Generate hierarchical user stories (epics, features, tasks) with formal Given/When/Then acceptance criteria. Works from brainstorm output or standalone. Produces structured requirements that feed directly into create-plan. Triggers on "create user stories", "write stories", "define requirements", "user story", or when presenting features that need requirements decomposition.
team-create-plan
by mhylle
Team-based implementation planning with adversarial design review. Spawns an Architect, Risk Analyst, and Researcher who explore competing designs and challenge each other before producing a plan. Use when planning complex features, high-stakes changes, or when multiple valid approaches exist. Triggers on "team create plan", "team plan", "deep plan", or when the user explicitly wants team-based planning.
workflow-guide
by mhylle
Helps choose between solo, small team, and full team workflow modes
team-implement-plan
by mhylle
Execute implementation plans with a small review team (Implementer + Reviewer + optional Integrator). The Implementer writes code directly while the Reviewer provides adversarial quality checks per phase. Use for moderate-to-complex plans where real-time adversarial review catches issues that automated checks miss. Triggers on "team implement", "team implement plan", or when the user explicitly wants team-based implementation.
team-brainstorm
by mhylle
Deep brainstorming using agent teams for adversarial multi-perspective analysis. Use when users want thorough idea exploration with real debate between independent perspectives. Triggers on "team brainstorm", "deep brainstorm", "brainstorm with team", "debate this idea", or when the user explicitly requests team-based analysis. Higher token cost but significantly deeper analysis than single-agent brainstorm.
code-review
by mhylle
Systematic code review for implementation phases verifying architectural principles, framework standards, ADR compliance, and code quality. This skill is invoked by implement-phase as part of its quality gate pipeline, or manually when reviewing code changes. Triggers on "review code", "code review", "/code-review", or automatically as Step 3 of implement-phase.
context-saver
by mhylle
Save session context to disk for seamless continuation in new chat sessions. This skill should be used when the user asks to save context, preserve work state, checkpoint progress, or prepare for session handoff. Triggers on "save context", "checkpoint", "save progress", "preserve state", or when explicitly asked to create a context file for later resumption. Optimizes for correctness, completeness, minimal size, and trajectory preservation.
agent-creator
by mhylle
Create composable AI agent systems in NestJS projects following the "tools all the way down" architecture. Use this skill when users want to: (1) Create new AI agents with orchestrator/planner/executor/evaluator components, (2) Build agentic systems that can call other agents as tools, (3) Implement DAG-based planning with parallel execution, (4) Add database-backed state persistence for agent runs, (5) Create custom evaluators for quality assurance. Triggers on "create agent", "build agent", "agent system", "agentic", "orchestrator", "planner/executor pattern", or NestJS AI agent requests.
eval-harness
by mhylle
Comprehensive evaluation framework for systematic testing, measurement, and quality assurance of AI-assisted implementations. Supports capability evals, regression testing, multiple grader types, and standardized metrics.
skill-visualizer
by mhylle
Generate interactive HTML visualizations of the skills collection, codebase structure, or dependency graphs. Uses D3.js for interactive visualization with collapsible nodes, color-coded categories, and hover details. Triggers on "visualize skills", "generate skill map", "codebase visualization", or "show skill dependencies".
strategic-compact
by mhylle
Strategic compaction suggestion framework that monitors session complexity and suggests context compaction at optimal logical boundaries rather than arbitrary thresholds.
prompt-generator
by mhylle
Generate implementation prompts for phase-based project execution using an orchestration pattern. Use when users request prompts for implementing project phases, need orchestration prompts for multi-step implementations, ask for "/prompt", "generate prompt", "create implementation prompt", or want to create structured implementation instructions for subagent delegation. Outputs the prompt to chat and saves to docs/prompts folder.
create-plan
by mhylle
Create detailed implementation plans through interactive research and iteration. This skill should be used when creating new implementation plans, designing feature specifications, planning technical work, or when the user asks to plan an implementation. Triggers on requests like "create a plan", "plan the implementation", "design how to implement", or when given a feature/task that needs structured planning before implementation.
implement-plan
by mhylle
Orchestrate the execution of complete implementation plans, delegating each phase to implement-phase skill. This skill manages the full plan lifecycle including phase sequencing, user confirmation between phases, and overall progress tracking. Triggers on "implement the plan", "execute the implementation plan", or when given a path to a plan file.
security-review
by mhylle
Comprehensive security audit for code changes. Use this skill when implementing authentication, authorization, user input handling, API endpoints, secrets/credentials, payment features, or file uploads. Provides security checklists, vulnerability patterns, and remediation guidance. Integrates with implement-phase as a security quality gate.
codebase-research
by mhylle
Orchestrates comprehensive codebase research by decomposing user queries into parallel sub-agent tasks and synthesizing findings. This skill should be used when users ask questions about how code works, where functionality exists, how components interact, or need comprehensive documentation of existing implementations. It focuses exclusively on documenting and explaining the codebase as it exists today.
verification-loop
by mhylle
Comprehensive 6-check verification framework for validating implementation quality across build, types, lint, tests, security, and diff review. This skill ensures code meets all quality gates before phase completion. Triggers on "verify implementation", "run verification", "/verification-loop", or automatically as part of implement-phase Step 2.
iterate-plan
by mhylle
Update existing implementation plans through user feedback with thorough research and validation. Also migrates old checkbox-based plans to the new Task tools system. This skill should be used when iterating on implementation plans, updating plans based on new requirements, refining technical approaches in existing plans, migrating old plans to Task tools, or when the user wants to modify a previously created plan file. Triggers on requests like "update the plan", "change the implementation approach", "iterate on this plan", "migrate to new system", or when feedback is provided about an existing plan document.
continuous-learning
by mhylle
Pattern extraction framework for learning from sessions. This skill captures valuable patterns discovered during work sessions including error resolutions, user corrections, workarounds, debugging techniques, and project-specific patterns. Triggers on Stop hook, end of session, "save learnings", "extract patterns", or when explicitly asked to capture knowledge from the current session. Outputs learned skills to ~/.claude/skills/learned/.
team-implement-plan-full
by mhylle
Execute implementation plans with a full team — one implementer per phase running in parallel where the dependency graph allows, plus a shared cross-phase Reviewer. Phases execute in waves based on dependencies. Use for large plans with 4+ phases and independent work streams. Highest token cost but fastest execution for parallelizable work. Triggers on "full team implement", "parallel implement", or when the user explicitly wants maximum parallelism.
implement-phase
by mhylle
Execute a single phase from an implementation plan with all quality gates. This skill is the unit of work for implement-plan, handling implementation, verification, code review, ADR compliance, and plan synchronization for ONE phase. Triggers when implement-plan delegates a phase, or manually with "/implement-phase" and a phase reference.
brainstorm
by mhylle
Interactive idea refinement using Socratic questioning methodology. This skill should be used when users want to explore an idea, find gaps in concepts, enhance proposals, or structure thoughts before implementation planning. Triggers on "brainstorm", "explore this idea", "find holes in", "help me think through", "what am I missing", or when presenting rough concepts that need refinement. Output integrates with create-plan skill.
adr
by mhylle
Document architectural decisions in standardized ADR format. This skill should be used when making significant technical decisions, choosing between approaches, establishing patterns, or when other skills (create-plan, implement-plan, brainstorm) identify decisions that need documentation. Triggers on "document decision", "create ADR", "architectural decision", or automatically when invoked by other skills during planning and implementation.
e2e-testing
by mhylle
Comprehensive E2E testing skill using Playwright MCP for systematic web application testing. This skill should be used when users need to test web-based systems end-to-end, set up test regimes, run exploratory tests, or analyze test history. Triggers on requests like "test my webapp", "set up E2E tests", "run the tests", "what's been flaky", or when validating web application functionality. The skill observes and reports only - it never fixes issues. Supports three modes - setup (create test regime), run (execute tests), and report (analyze results).
