Give your AI a useful way to work.

Building your whole AI setup?

Skill Vault adds one repeatable behavior at a time. If your AI still needs the context, boundaries, and first workflow those Skills should fit into, start with Home Base.

Start with Home Base

Public release v0.1.2 — install the latest source or pin the tested release.

Install latest

npx skills@latest add MattEspo23/skills --skill '*'

Reproducible install

npx skills@latest add 'MattEspo23/skills#v0.1.2' --skill '*'

Clean installs are verified for Codex and Claude Code. The installer copies editable files into the selected agent; review every Skill before giving it tool access.

Choose by when you reach for it

The Vault is organized around the moment a behavior becomes useful.

Getting Started

Set up the collection once, then find the right path for the situation you are in. Start here

• The /setup-espo-skills Skill /setup-espo-skills: Configure one repository so the rest of the engineering Skills know where its work and context live. Public adapted baseline · video planned
• The /ask-espo Skill /ask-espo: Describe your situation and get the Skill or sequence that fits, plus the human decisions along the way. Public adapted baseline · video planned

The Main Flow

Move from a loose idea to specified, tested, and reviewed work. Start here

• The /grill-with-docs Skill /grill-with-docs: Get interviewed about a plan while recording the shared language and durable decisions it creates. Public adapted baseline · video planned
• The /to-spec Skill /to-spec: Turn an already-settled conversation into a written specification without reopening the interview. Public adapted baseline · video planned
• The /to-tickets Skill /to-tickets: Split a specification into tracer-bullet tickets with explicit blocking relationships. Public adapted baseline · video planned
• The /implement Skill /implement: Build work that has already been decided, using agreed seams, tests, and a final review. Public adapted baseline · video planned
• The /code-review Skill /code-review: Review a diff separately against repository standards and the specification it was meant to implement. Public adapted baseline · video planned

Shaping

Explore an open question and produce the decision or evidence that lets work continue. Start here

• The Semantic Tree /semantic-tree: Turn a vague idea into a structured map of what matters, what connects, and what to decide next. Public EspoAI original · video planned
• The /wayfinder Skill /wayfinder: Chart a large, foggy effort as a map of decision tickets and resolve them until the route is visible. Public adapted baseline · video planned
• The /prototype Skill /prototype: Write throwaway code that answers one design or behavior question you cannot settle by talking. Public adapted baseline · video planned
• The /research Skill /research: Investigate a question against primary sources and leave a cited answer in the repository. Public adapted baseline · video planned

Upkeep

Keep the codebase, issue queue, setup, and operational edges healthy. Start here

• The /improve-codebase-architecture Skill /improve-codebase-architecture: Find modules worth deepening and present the strongest refactoring candidates as a visual report. Public adapted baseline · video planned
• The /diagnosing-bugs Skill /diagnosing-bugs: Diagnose a hard bug through a tight failing loop before proposing or implementing the fix. Public adapted baseline · video planned
• The /resolving-merge-conflicts Skill /resolving-merge-conflicts: Resolve an active merge or rebase conflict hunk by hunk using each side’s original intent. Public adapted baseline · video planned
• The /triage Skill /triage: Move incoming issues and external pull requests through a small, evidence-backed triage state machine. Public adapted baseline · video planned
• The /wizard Skill /wizard: Generate an interactive script for setup steps only a person can complete. Public adapted baseline · video planned

Productivity Skills

Human-facing workflows for thinking, learning, continuity, and communication. Start here

• YouTube Action Plan /youtube-action-plan: Turn a useful video into a focused plan you can apply, test, and revisit instead of another pile of notes. Public EspoAI original · video planned
• The /grill-me Skill /grill-me: Turn a loose idea into real decisions through a rigorous conversation in question rounds. Public adapted baseline · video planned
• The /handoff Skill /handoff: Compact a long conversation into a portable handoff another agent or person can continue. Public adapted baseline · video planned
• The /to-questionnaire Skill /to-questionnaire: Turn open questions into a document for the person who actually holds the missing knowledge. Public adapted baseline · video planned
• The /teach Skill /teach: Learn a topic over multiple sessions through small lessons, practice, and durable learning records. Public adapted baseline · video planned
• The /wait-what Skill /wait-what: Ask the agent to re-pitch its last message with missing context and plain language. Public adapted baseline · video planned
• The /writing-for-agents Skill /writing-for-agents: Write Skills and instruction documents that agents can discover, load, and follow predictably. Public adapted baseline · video planned

Reference Skills

Reusable disciplines and vocabulary that strengthen the other workflows. Start here

• The /grilling Skill /grilling: The reusable interview discipline behind Skills that stress-test plans and decisions. Public adapted baseline · video planned
• The /codebase-design Skill /codebase-design: Use a shared vocabulary for designing deep modules with small interfaces and strong seams. Public adapted baseline · video planned
• The /domain-modeling Skill /domain-modeling: Sharpen a project’s vocabulary and record domain terms and durable decisions when they become settled. Public adapted baseline · video planned
• The /tdd Skill /tdd: Build behavior through a red-green-refactor loop at a stable, meaningful seam. Public adapted baseline · video planned

Set the behavior up once

A prompt helps with one conversation. A Skill packages the behavior, inputs, checks, and boundaries so your agent can use it again without rebuilding the method.

Try the core behavior first

When it is safe and useful, a Skill can include a source-backed Try once instruction. Installation remains the recurring path; the trial is there to help you evaluate it.
