How to use the Agent Skill Stack Builder agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
Agent Skills are folders of instructions, and sometimes scripts, that an AI agent such as Claude loads when a task matches them. The agent-skill-stack skill helps you build a set of skills for a larger goal: it works out what you want to achieve, looks for skills that could help, checks each one for overlap, safety and fit, and recommends the smallest combination you need. This guide shows you how to install it, how to ask for it in plain language, and what it needs before you start.
Agent Skill Stack Buildergithub/awesome-copilot · MIT Download the skill Quick start
- 1Download and unzip. Download the skill ZIP from the directory page and unzip it into a folder on your computer.
- 2Place the skill folder. Copy the unzipped folder into ~/.claude/skills/ for personal use, or into the project's .claude/skills/ folder for one project.
- 3Or upload in the Claude apps. In the Claude apps, open Settings → Capabilities → Skills and upload the skill.
- 4Confirm Python 3 is available. The bundled scripts need Python 3. Make sure it is installed before you ask for a stack build.
- 5Describe your outcome. Tell the agent the result you want and the project it applies to, in ordinary language.
- 6Review the plan. Read the recommended combination, the reasons for each choice and the decisions that need your approval.
- 7Approve installs deliberately. Install only the skills you have reviewed, and approve any account access or external actions yourself.
What the agent-skill-stack skill makes the agent do
When installed, the agent works out the outcome you want, searches your local skill folders and online registries for skills that could help, checks each candidate for overlap, safety and fit, and recommends the smallest combination needed. It explains the plan in plain language and keeps technical details in the background unless you ask for them.
It is meant for multi-step work, such as a project that needs several AI skills working together. It is not the right tool for finding one well-known skill; the separate find-skills workflow is more direct for that.
- Finds candidate skills in local folders, registries, GitHub and OpenCLI
- Compares how widely each skill is used, whether it fits, its safety, and how much it overlaps with others
- Recommends Required, Helpful, Alternative and Not recommended options
- Audits installed skills for overlap or conflicts
Install the agent-skill-stack skill
Download the ZIP for the skill from the directory page and unzip it. Then put the skill folder in one of two places, depending on how you want to use it.
For all your projects, place it in ~/.claude/skills/. To limit it to one project, place it in that project's .claude/skills/ folder. If you use the Claude apps instead, open Settings → Capabilities → Skills and upload the skill there.
- Personal use across projects: ~/.claude/skills/
- One project only: the project's .claude/skills/ folder
- Claude apps: Settings → Capabilities → Skills, then upload
Check the requirements before you run it
The skill runs bundled scripts and uses the network for online discovery. Python 3 is needed to run the bundled index, profile and rendering scripts. Network and GitHub or registry access are optional and need your approval. Browser-backed OpenCLI tooling is optional and is used for some broad web searches.
If your environment must not run local scripts or contact the internet, do not use this skill, because its workflow relies on both.
- Python 3 installed
- Network access and GitHub or registry access, for online discovery (optional, needs approval)
- Browser-backed OpenCLI tooling, for some broad web searches (optional)
Trigger the skill with natural requests
You do not need to name the skill. Describe the outcome you want and which project it applies to. The skill is meant for requests such as building a multi-step workflow, asking which skills fit a project, auditing installed skills for conflicts, or wanting a project-specific stack with controlled installation. It also covers indirect helpers such as humanizers or compliance checks.
Describe the goal, not the tools. The agent will ask only the questions that change the result, cost or access it needs.
- "Which skills would help me build a weekly report pipeline for our team project?"
- "Check my installed skills for overlap or conflicts."
- "I need a project-specific skill setup for a multi-step content workflow, with safety checks."
- "Find a helper that makes our drafts sound more natural and check it before installing."
Review the recommendations before installing
Candidates come from third-party sources, so the skill is designed to present them for review rather than install them silently. The default answer lists what you already have, the recommended combination, why each item was chosen, and what needs your decision, such as account access, paid services, external publishing or which installation to select.
Do not use it unsupervised to install skills without review. You can ask for technical details when you need them, including source paths and safety evidence.
- Read the What you already have section to avoid duplicate installs
- Check the safety and safe-trial notes for each recommended skill
- Approve or decline any account access or external action before it happens
What people use it for
- Assembling a set of skills for a multi-step project before work starts
- Auditing installed skills for overlap or conflicts that could confuse the agent
- Finding a helper, such as a natural-writing or compliance check, that fits a step in an existing workflow
- Creating a project-specific skill setup kept inside one project's .claude/skills/ folder
Frequently asked questions
How do I install the agent-skill-stack skill?
Download the skill ZIP from the directory page and unzip it. Put the folder in ~/.claude/skills/ for personal use or in the project's .claude/skills/ folder for one project. In the Claude apps, you can instead upload it under Settings → Capabilities → Skills.
What does the agent-skill-stack skill require?
It requires Python 3 to run its bundled index, profile and rendering scripts. Network and GitHub or registry access are used for online discovery and need your approval, and browser-backed OpenCLI tooling is optional for some broad web searches. It runs scripts and uses the network.
Is the agent-skill-stack skill free?
The skill is published under the MIT licence on the github/awesome-copilot repository. The source does not list prices, so check the repository and the directory page for current terms.
When should I not use this skill?
Do not use it to find one well-known skill; the separate find-skills workflow is more direct. Also avoid it where the agent must not run local scripts or contact the internet, and avoid unsupervised installs without review.
Can it run without internet access?
Online discovery depends on network and registry access, which is optional and needs approval. The skill's workflow relies on both scripts and the network, so it is not suitable for environments that block either.
Is it safe to let the agent install skills?
Candidates come from third-party sources, so the skill presents them for human approval rather than installing them unsupervised. Review each recommendation and its safety notes, and approve any account access or external action yourself.

Our verdict
Use this skill if you are building a project that needs several AI skills working together, or if you want to audit installed skills for overlap and conflicts before trusting them. Pick the find-skills workflow instead if you only need one known skill, and avoid this one in environments that must not run local scripts or access the internet.
