team-building

team-building is a skill for Claude Code, Codex from markus-global/markus. It costs 18 tokens per session (5,386 once invoked), scanned A, original, Apache-2.0.

A guide for creating Markus team packages: folders that define several specialized AI agents, their roles, shared rules, and workflows. The package includes a manifest and public documentation.

In plain words
What is it for?
Use it to design specialist agents, write their policies and shared norms, create team metadata and announcements, and place the required files in the expected builder-artifacts directory.
Why use it?
It provides a fixed structure for building teams whose agents have distinct responsibilities and consistent working norms. This makes the resulting team package installable and understandable.

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 A, and why

team-building scanned grade A with 0 findings 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 4d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 400 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Team Building

This skill teaches you how to create Markus team packages — self-contained directory-based artifacts that define a group of specialized AI agents with shared norms and coordination structure.

Core Philosophy

Every agent in a team must be a specialist. Do NOT simply pick generic templates and give them names. Design each agent with a unique identity, expertise, and detailed role documentation. Safety constraints are defined in each agent's POLICIES.md, not through tool restrictions.

Artifact Directory

CRITICAL: Team artifacts MUST be saved under this exact path — the Builder page, install system, and deliverable detection all depend on it:

~/.markus/builder-artifacts/teams/{team-name}/

What ships with it

Changes

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.
