team-builderTeam Builder is a skill in affaan-m/ECC (276k stars). Its SKILL.md is about 1.1k tokens. Licence: MIT.
2 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 4eb71d9. It shows what the files ask for, not the result of running them.
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.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Team Builder loads about 1.1k tokens when it runs. Until then it costs about 13 tokens; SKILL.md has 110 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.
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.

.claude/skills/team-builder/SKILL.md (or your agent's skills folder).オンデマンドでエージェントチームを閲覧・構成するためのインタラクティブメニュー。フラット構成またはドメインサブディレクトリで整理されたエージェントコレクションに対応する。
エージェントファイルはロール、プロンプト(アイデンティティ、ルール、ワークフロー、成果物)を含むmarkdownファイルである必要がある。最初の # Heading がエージェント名として使用され、最初の段落が説明として使用される。
フラット構成とサブディレクトリの両方のレイアウトをサポートする:
サブディレクトリレイアウト —— ドメインはフォルダー名から推論される:

│ ├── security-engineer.md
│ └── software-architect.md
├── marketing/
│ └── seo-specialist.md
└── sales/
└── discovery-coach.mdフラットレイアウト —— ドメインは共有のファイル名プレフィックスから推論される。2つ以上のファイルが同じプレフィックスを共有する場合、そのプレフィックスはドメインとみなされる。ユニークなプレフィックスを持つファイルは「General」カテゴリーに分類される。注意:アルゴリズムは最初の - で分割するため、複数単語のドメイン(例:product-management)にはサブディレクトリレイアウトを使用する:

└── sales-outbound-strategist.mdエージェントディレクトリは順番に探索され、結果がマージされる:
./agents/**/*.md + ./agents/*.md —— プロジェクトローカルのエージェント(両方の深さ)~/.claude/agents/**/*.md + ~/.claude/agents/*.md —— グローバルエージェント(両方の深さ)すべての場所の結果がマージされ、エージェント名で重複排除される。同名の場合、プロジェクトローカルのエージェントがグローバルエージェントより優先される。ユーザーがカスタムパスを指定した場合、そのパスを代わりに使用する。
上記の探索順序を使用してエージェントディレクトリでグローバル検索を実行する。READMEファイルを除外する。見つかった各ファイルに対して:

利用可能なエージェントドメイン:
1. エンジニアリング — ソフトウェアアーキテクト、セキュリティエンジニア
2. マーケティング — SEOスペシャリスト

ドメインを選択するか、特定のエージェントを指定してください(例:「1,3」または「security + seo」):柔軟な入力を受け付ける:
5つ以上のエージェントが選択された場合、アルファベット順にリストアップして絞り込みを求める:「Nつのエージェントを選択しました(最大5つ)。どれを保持するか選択するか、アルファベット順の最初の5つを使用する場合は 'first 5' と言ってください。」

Hands-on implementation partner for creating tools, scripts, dashboards, and prototypes.
dralgorhythm/claude-agentic-framework
Translate plans into working, tested code through implementation, debugging, and refactoring — a user-invoked Builder workflow.
n8n-io/n8n

anthropics/skills
Guides the design and implementation of Model Context Protocol servers in TypeScript or Python, from tool naming and error messages to evaluation.
affaan-m/ECC
Audits your installed Claude skills and commands for quality, with a quick mode for recently changed skills and a full mode that evaluates all of them through subagents.
affaan-m/ECC
Ingests, indexes, searches, edits and monitors video, audio and live streams through the VideoDB Python SDK, returning stream links, clips and timestamps.
affaan-m/ECC
Route broad documentation-governance requests to existing ECC skills and run an opt-in, read-only audit of mapped documentation roles, links, ADR indexes, and evidence references.
affaan-m/ECC
Scans installed skills for principles that recur across them and proposes rule-file changes: append, revise, add a section, create a file or leave as covered.
affaan-m/ECC
Builds DRAFT counterparty agreements from one markdown template and a small JSON spec per party, with clauses picked by the party's role.
affaan-m/ECC
Measures whether agents actually follow a skill, rule or agent definition by generating scenarios at three strictness levels and scoring tool-call traces.
Run `npx skills add affaan-m/ECC --skill team-builder -a claude-code`. Or copy the skill folder (docs/ja-JP/skills/team-builder in affaan-m/ECC) into .claude/skills/team-builder in your project. Claude Code loads it when a task matches its description.
Run `npx skills add affaan-m/ECC --skill team-builder -a codex`. Or copy the skill folder (docs/ja-JP/skills/team-builder in affaan-m/ECC) into .agents/skills/team-builder in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add affaan-m/ECC --skill team-builder -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/team-builder, .gemini/skills/team-builder, .github/skills/team-builder and .opencode/skills/team-builder in your project.
SKILL.md names no scripts, command-line tools or credentials: Team Builder is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Team Builder is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.1k tokens (SKILL.md is roughly 4.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Team Builder: Builder (jeremylongshore/tons-of-skills-marketplace, 2.8k stars), Builder (dralgorhythm/claude-agentic-framework, 125 stars), Workflow Builder (n8n-io/n8n, 207k stars) and Agent Builder (n8n-io/n8n, 207k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
