What it does

Cc Dev Agent is an agent skill from sangrokjung/claude-forge. Use when starting Claude Code projects, writing CLAUDE.md/spec.md, dispatching subagents, or requesting Agent Teams parallel development. Covers Spec-Driven Development, Context Engineering, and post-dev workflow.

Its SKILL.md is about 770 tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `references/context-engineering.md`, `references/playwright-agents.md` and `references/post-dev-workflow.md`).

It sits in Agent Workflows, covering Subagents, Context engineering and Spec-driven development. The repository describes itself as: oh-my-zsh for Claude Code — 16 agents, 35 commands, 32 skills, 21 safety hooks in one install. v4.0 adds an adversarial review loop: a second agent that never sees the first… The licence is MIT.

When your agent uses it

  • Starting Claude Code projects
  • Writing CLAUDE.md/spec.md
  • Dispatching subagents
  • Requesting Agent Teams parallel development

Example prompts

  • “/cc-dev-agent”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Context Engineering: 제한된 컨텍스트 윈도우에서 토큰 유용성 최적화
  2. Spec-Driven: 코드 전에 스펙(spec.md) 먼저 → 반복 수정 8배 감소
  3. TDD Loop: Red(테스트) → Green(구현) → Refactor
  4. Sub-agents 활용: Explore, Plan 에이전트로 작업 분산
  5. 작성-검증 분리: /clear 후 새 눈으로 검증 (Boris 원칙)

What it can do on your machine

Read from SKILL.md and the folder at commit 34d881d. 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 (its code samples are bash and gitignore).

    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

Cc Dev Agent loads about 771 tokens when it runs, and up to ~11k if it reads all its reference files. Until then it costs about 57 tokens; SKILL.md has 301 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~771
With references · SKILL.md plus every file in references/, read only if the agent opens them
~11k

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.

Claude Code Agent

Claude Code를 활용한 Spec-Driven 개발 워크플로우 및 Context Engineering 가이드.

핵심 원칙

  1. Context Engineering: 제한된 컨텍스트 윈도우에서 토큰 유용성 최적화
  2. Spec-Driven: 코드 전에 스펙(spec.md) 먼저 → 반복 수정 8배 감소
  3. TDD Loop: Red(테스트) → Green(구현) → Refactor
  4. Sub-agents 활용: Explore, Plan 에이전트로 작업 분산
  5. 작성-검증 분리: /clear 후 새 눈으로 검증 (Boris 원칙)

병렬 개발 (Agent Teams v6)

Git Worktree 기반 병렬 개발은 레거시. Agent Teams가 팀 생성/정리를 자동 처리.

전제조건
  • CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS를 1로 설정
  • 설정 위치: ~/.claude/settings.json의 env 또는 셸 환경변수

개발 완료 후 워크플로우 (Boris 방식)

"Give Claude a way to verify its work. If Claude has that feedback loop, it will 2-3x the quality."
