What it does

Deep Dive is an agent skill from byungjunjang/jangpm-meta-skills. A Codex skill for Socratic interviews that deepen a spec or refine an existing agent blueprint. Conducts forcing-question interviews, challenges premises, generates alternatives, and validates the final document with a document-grounded reviewer pass. Use when the user asks for "$deep-dive", "deep dive", "interview me", "create a spec", "요구사항 정리", "기획서 만들어", "스펙 작성", "blueprint 심화", or "설계 보강", or when they have a rough idea or an existing blueprint that needs structured stress-testing in Codex.

Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `agents/openai.yaml`, `references/agent-design-questions.md` and `references/anti-patterns.md`).

It sits in Agent Workflows, covering Load testing, Requirements gathering and Tutoring and explanations. The repository describes itself as: AI에게 일을 시키는 프롬프트가 아닌, AI가 일하는 방식을 설계하는 메타 스킬 4종 — 설계(blueprint) · 인터뷰(deep-dive) · 개선(reflect) · 자기 검증개선(autoresearch).

When your agent uses it

  • The user asks for $deep-dive
  • They have a rough idea
  • An existing blueprint that needs structured stress-testing in Codex

Example prompts

  • “$deep-dive”
  • “deep dive”
  • “interview me”
  • “/deep-dive”

Workflow steps

7 steps, taken from the step headings in SKILL.md.

  1. Context & Doc Scan
  2. Topic Framing + Blueprint 로딩
  3. Forcing Interview
  4. Premise Naming
  5. Alternative Framings (MANDATORY)
  6. Write / Update Spec
  7. Spec Review Loop

What it can do on your machine

Read from SKILL.md and the folder at commit 41af514. 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

    Shell commands in SKILL.md call:

    • rg

    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

Deep Dive loads about 2.7k tokens when it runs, and up to ~9.7k if it reads all its reference files. Until then it costs about 128 tokens; SKILL.md has 1,581 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~128
When it runs · the whole SKILL.md, loaded when a task matches
~2.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~9.7k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,581 words (~2,681 tokens).

“Clarify ambiguous work or stress-test an existing design through a forcing-question interview, surface hidden premises, generate alternatives, and validate the final spec with a document-grounded reviewer pass.”
