explore-unknowns

explore-unknowns is a skill for Claude Code, Codex from dzhng/duet-agent. It costs 162 tokens per session (1,026 once invoked), scanned A, a copy of explore-unknowns, Apache-2.0.

A guided conversation method for mapping what is known and unknown about an ambiguous task. It separates known facts, known gaps, overlooked information, and risks that nobody has identified yet.

In plain words
What is it for?
Use it to clarify underspecified work, identify assumptions and risks, compare possible directions, and finish with a complete map that can guide a later implementation task.
Why use it?
It exposes missing information before implementation begins, when resolving uncertainty is cheaper and less disruptive. The process also helps users react to concrete options instead of trying to describe everything from scratch.

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

explore-unknowns 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Explore Unknowns

The map is not the territory. The prompt, the plan, and the context window are the map; the codebase, the domain, and the user's actual intent are the territory. The gap between them is the unknowns — and an unknown found before code is written costs minutes, while the same unknown found three PRs later costs the three PRs.

This skill is a guided conversation: the quadrant walk. Together with the user you fill in a four-quadrant map of the task, one quadrant per stage, and the user walks away holding the completed map. The map is the deliverable; implementation is a different task that starts only after the map is handed over.

Two moves apply at every stage:

  • Reacting beats imagining. Never ask the user to describe what they want when you can hand them something concrete to react to — a rendered option, a clickable mock, a decisions table. Reacting extracts knowledge the user has but cannot articulate unprompted.
  • Every artifact assembles the reply. End each artifact with the user's next message pre-drafted: steal/skip chips, resonate checkboxes, a decisions table, a copyable sharpened prompt — so their reaction becomes their next message with near-zero typing.

The Quadrant Walk

Five stages, walked in order, one at a time. When you enter a stage, read its reference file and follow it. Name the current quadrant as you go — the user should always know where they stand on the map — and finish the stage in front of you before opening the next.

  1. Known knowns — scan the territory, then open with the settled ground.
  2. Known unknowns — the questions you can name; resolve them one at a time.
  3. Unknown knowns — extract the taste and tacit context nobody has put into words.
  4. Unknown unknowns — sweep the territory for landmines.
  5. Hand over the map — the completed four-quadrant map, the walk's only done-condition.

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.
