A setup guide for forming a software-development team of agents and choosing a development method for a project.

Use it to choose between solo, single-team, programme, or assured development, inspect the current setup, and install matching team plugins.

It first checks existing plugins, agents, and skills, helping avoid duplicate installations and making recommendations fit the project’s language, technology, and support needs.

setup-team — Skill for Claude Code by SteveGJones

Install

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.

Any agent

npx skills add SteveGJones/ai-first-sdlc-practices --skill setup-team

Clone the repo

git clone --depth 1 https://github.com/SteveGJones/ai-first-sdlc-practices

Made for: Claude Code.

Or install sdlc-core, the plugin that ships this one along with the rest of its 10 skills, 5 agents, 2 hooks.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00055	$0.08465
Opus 5	$0.00028	$0.04233
Sonnet 5	$0.00011	$0.01693
Haiku 4.5	$0.00006	$0.00847

Security

Grade B, and why

setup-team scanned grade B 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 9d 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

SDLC Team Setup

Configure the right agent team for this project by selecting an SDLC method, a project type, and installing the matching team plugins.

Steps

Pre-check: inventory what's already installed

Before making any recommendations, check what plugins, agents, and skills are already available — both globally and for this project.

0a. Check installed plugins:
- Read ~/.claude/settings.json → enabledPlugins field (global installs)
- Read .claude/settings.json (project-level) → enabledPlugins field (if it exists)
- Merge both lists. For each sdlc-*@ai-first-sdlc entry: record as installed.
- Also check for sdlc-knowledge-base@ai-first-sdlc, sdlc-programme@ai-first-sdlc, and sdlc-assured@ai-first-sdlc specifically — these may be relevant to the SDLC method question in step 3.
0b. Check available agents:
- Glob .claude/agents/**/*.md (project-level agents)
- Note which come from installed plugins vs which are project-local
0c. Check available skills:
- List currently registered skills (the set Claude Code can see)
0d. Present the pre-check results to the user before any recommendations:
```
Current state:

Installed SDLC plugins:
  ✓ sdlc-core@ai-first-sdlc (global)
  ✓ sdlc-team-common@ai-first-sdlc (global)
  ✗ sdlc-team-fullstack@ai-first-sdlc
  ✗ sdlc-lang-python@ai-first-sdlc
  ✗ sdlc-knowledge-base@ai-first-sdlc
  ✗ sdlc-programme@ai-first-sdlc
  ✗ sdlc-assured@ai-first-sdlc

Available agents: N (from installed plugins)
Available skills: M

I'll only recommend what you don't already have.
```
0e. Record the pre-check state for use in later steps — the recommendation output (step 8) will mark already-installed plugins with ✓ (already installed) instead of install commands, and the install command list (step 9) will exclude them.
Check current team configuration

Look for .sdlc/team-config.json in the project root (or .claude/team-config.json as a fallback). If it exists, display the current formation and the recorded sdlc_method (if present) and ask if the user wants to reconfigure.

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.

setup-team is a skill published in the GitHub repository SteveGJones/ai-first-sdlc-practices (41 stars, last pushed 1mo ago), licensed MIT. It adds 55 tokens to every session and 8,465 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
