What it does
Scaffold Agent is an agent skill from strands-agents/harness-sdk. Scaffold a new Strands agent or add Strands to an existing Python or TypeScript project. Use when the user asks to create, initialize, or start an agent with Strands, including choosing between Strands harness and the lower-level SDK.
Its SKILL.md is about 200 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development. It works with Python and TypeScript. The repository describes itself as: Build an agent harness and control it end-to-end. Open-source SDK for production AI agents in Python & TypeScript - any model, any cloud. The licence is Apache-2.0.
When your agent uses it
- The user asks to create
- Start an agent with Strands
- Including choosing between Strands harness and the lower-level SDK
Example prompts
- “/scaffold-agent”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit e519d67. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Scaffold Agent loads about 204 tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 66 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Scaffold a new Strands agent or add Strands to an existing Python or TypeScript project. Use when the user asks to create, initialize, or start an agent with Strands, including choosing between Strands harness and the lower-level SDK.
Scaffold a Strands agent
Read the shared Strands skill and the scaffold guide completely, then create the smallest runnable agent that matches the project's language, package manager, model provider, and existing conventions.
Do not add tools, persistence, deployment, or infrastructure unless the requested first behavior needs them. Run the entrypoint when credentials are available; otherwise validate imports, types, and configuration without making a billable model call.
