Extreme Clarity

goodthinking is a set of strategic thinking skills from Extreme Clarity for problem understanding, decision making, and ideation. It is built around multiple AI subagents and is described as using context-blind agents that do not receive conversation context, so they can offer fresh perspectives rather than remaining anchored to the user’s framing. The page also says that dissent and disagreement are preserved, with conflicting views presented as-is for the user to resolve.

The skills are grouped into understanding, decision making, and ideation. For understanding, goodthinking can sharpen a problem statement by creating an initial framing and then having a context-blind agent check it for precision, clarity, completeness, and scope; if gaps appear, it asks targeted clarifying questions, and a second agent can suggest a different level of abstraction. It can also break a problem into parts and check whether the components are mutually exclusive, collectively exhaustive, at uniform abstraction levels, and actionable. For decision making, it can stress-test a thesis by spawning two parallel agents that argue for and against it, and it can challenge a decision to surface hidden assumptions, practical risks, opportunity costs, and second-order effects. Another skill audits an option set for completeness against seven listed integrity criteria: missing options, dimensional collapse, description asymmetry, criteria rigging, false exclusivity, scope mismatch, and constraint fabrication.

For ideation, the tool frames a topic as How Might We questions and uses 2–4 different lenses, each with its own parallel agent, to generate diverse ideas from different perspectives. It can also deduplicate, cluster, and group a raw list of ideas into themes, then validate that those themes are MECE, actionable, and collectively complete. The page says these skills can use up context quickly.
