deep-dive

deep-dive is a skill for Claude Code, Codex from fabioc-aloha/Alex_Skill_Mall. It costs 29 tokens per session (1,364 once invoked), scanned A, original, MIT.

A deep-research workflow that breaks a question into connected sub-questions, investigates them in parallel, checks for gaps, and combines the findings.

In plain words
What is it for?
Use it to plan and run multi-step research, follow dependencies between questions, identify missing information, and synthesize findings.
Why use it?
It gives broad research tasks a structured process and revisits unanswered parts before producing the result.

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

deep-dive 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 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.

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.

Deep Dive

Autonomous deep research using the same DAG-based planning pattern as Google's Deep Research — but running entirely on Claude Code with no external dependencies.

How it works

  1. Plan — decompose the question into a DAG of sub-questions with dependencies
  2. Fan out — run independent sub-questions in parallel via Agent subagents
  3. Gap analysis — each subagent returns findings + identified gaps
  4. Iterate — gaps become new sub-questions, fed back into the DAG
  5. Synthesize — once all nodes complete, produce a final report

Steps

1. Decompose into a DAG

Given the research question, generate a DAG of sub-questions. Each node has:

  • id: short identifier (e.g., q1, q2a)
  • question: the specific sub-question to research
  • depends_on: list of node IDs whose answers are needed first (empty = no dependencies)

Rules for decomposition:

  • Start with foundational/context-setting questions that have no dependencies
  • Build toward analytical/comparative questions that depend on foundational answers
  • Aim for 4-8 nodes. If the topic needs more, cap at 12.
  • Each node should be answerable with 1-3 web searches
  • Questions should be specific enough that a researcher with no other context can answer them

Print the DAG as a table so the first brain can see the plan, then immediately proceed to execution — do not wait for confirmation.

Create a task for each DAG node using TaskCreate (description: the sub-question, status: pending). Also create tasks for "Gap analysis" and "Synthesize report". Update each task to in_progress when its wave launches and completed when the subagent returns. This gives the first brain real-time visibility into progress.

| ID | Question | Depends on |
|----|----------|------------|
| q1 | ...      | —          |
| q2 | ...      | —          |
| q3 | ...      | q1         |
| q4 | ...      | q1, q2     |

2. Execute in dependency order

Process the DAG in topological order:

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.

deep-dive is a skill published in the GitHub repository fabioc-aloha/Alex_Skill_Mall (4 stars, last pushed 2d ago), licensed MIT. It adds 29 tokens to every session and 1,364 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
