fullstack-agent

A team-lead agent that researches a software project, designs a solution, writes specifications, and plans the work. It creates and coordinates a group of specialist coding agents.

In plain words
What is it for?
Use it to coordinate a software build from initial research through review. It helps divide work among agents and manage the build-and-check cycle.
Why use it?
It removes the need to organize research, planning, implementation, and review by hand. Shared tasks and messages keep the agents aligned as work progresses.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

fullstack-agent scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

fullstack-agent is an agent published in the GitHub repository aws-samples/sample-claude-code-agent-team (55 stars, last pushed 5d ago), licensed MIT-0. It adds 38 tokens to every session and 10,176 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
