Command
Run the Plan-Do-Check-Act improvement loop as a chain of shipped moves, taking a performance gap through root-cause and countermeasure choice, then a structured review of actual versus expected, then a standardize-or-iterate decision.

Command
Make sure you are solving the right problem before generating solutions, by restating it, sorting evidence from inference, and reviewing it through separated lenses.
product-on-purpose/thinking-framework-skills
Command
Research a thinking framework and produce its evidence-graded dossier plus a schema-valid proposed registry entry, or discover candidate methods in a family. Use to vet a method before building it into a skill, reproduce the evidence-and-overlap vetting, or shortlist new candidates.
product-on-purpose/thinking-framework-skills
Command
Pressure-test a consequential decision before committing, by comparing options, surfacing the conditions that must hold, imagining failure, and sanity-checking the estimate against base rates.

Skill Claude CodeCodex
Builds an abstraction ladder that moves a problem up ("why / to what end?") and down ("how / what specifically?") to locate the right altitude to work at, then marks one rung as the working level. Use when a problem is stated as a bare solution with an unstated purpose, as a vague aspiration with no concrete handle…

Skill Claude CodeCodex
Produces a clustered theme map that groups many raw notes, observations, quotes, or data points bottom-up into a small set of named, traceable themes (the KJ method). Use when a scattered pile of dozens to hundreds of existing items needs to become a few emergent themes, such as synthesizing user-research notes…

Skill Claude CodeCodex
Produces a structured after-action review by comparing what was expected against what actually happened, diagnosing why the gaps occurred, and converting them into specific owned sustain-and-change actions. Use when a project, launch, sprint, or incident has finished and you want to turn the outcome into learning, not…

Handles a by-name request for ACH (Analysis of Competing Hypotheses), the evidence-by-hypothesis disconfirmation matrix, honestly. Controlled trials found ACH raises confidence with no accuracy gain and does not reduce confirmation bias, so this skill does NOT build the matrix as if valid. It leads with that evidence…

Skill Claude CodeCodex
Produces an argument map by laying out a claim's supporting reasons, the co-premises each silently depends on, and the objections against it as an explicit structure, then flags the weakest links and unsupported premises. Use when an argument or recommendation must be evaluated for soundness, or when a fluent case may…
product-on-purpose/thinking-framework-skills
Skill Claude CodeCodex
Generates non-obvious ideas by surfacing the foundational assumptions a problem or solution rests on, negating each, and reframing from the reversed assumptions, then shortlisting, producing an assumptions-and-reversals sheet. Use when an option space feels stuck inside default constraints, or when you need to expose…
product-on-purpose/thinking-framework-skills
Skill Claude CodeCodex
Checks whether a decision has genuine minority dissent or only smooth surface consensus, identifies who actually holds a contrary view, and plans how to elicit and protect real dissent, flagging clearly where a view is constructed rather than authentically held. Use when consensus feels too easy, or to set up genuine…

Skill Claude CodeCodex
Produces a backcast path by fixing a vivid desired future state and reasoning backward through the milestones and preconditions required to reach it, ending at the next concrete step available now. Use when planning toward a transformative or long-horizon goal that forward planning anchors too low, when a chosen…

Skill Claude CodeCodex
Produces a belief-update ledger that re-scores a standing inventory of open beliefs against newly arrived evidence on a cadence - each belief carrying a prior confidence, the evidence accrued since the last review, a revised confidence with an explicit delta and direction, a reason for the size of the move (a guard…

Skill Claude CodeCodex
Audits the boundary judgments that silently define a problem frame. For each of four sources, who benefits, who decides, whose knowledge counts, who has standing, it contrasts the descriptive is boundary against the normative ought boundary, names the gaps, and lists the affected-but-excluded parties who have no voice…
product-on-purpose/thinking-framework-skills
Skill Claude CodeCodex
Generates ideas the way silent parallel brainwriting does, producing several independent idea streams that build on each other without anchoring on the first voice, then consolidates them into a shortlisted idea pool. Use when you need breadth of options and want to avoid the anchoring and conformity that make…
product-on-purpose/thinking-framework-skills
Skill Claude CodeCodex
Produces a four-layer matrix (litany, system, worldview, myth) of the current 'used future' beside a reconstructed preferred future per layer, anchored by a deliberately changed deep metaphor. Use when an issue is stuck because the framing is stuck, the official account and the system explanation have been argued to…
product-on-purpose/thinking-framework-skills
Skill Claude CodeCodex
Builds a signed causal loop diagram by closing the feedback loops in a situation, labeling each loop reinforcing (R) or balancing (B) with its link polarities, and reading likely dynamics (spiral, goal-seeking, or oscillation) off which loop dominates. Use when a situation feeds back on itself - growth that funds more…
product-on-purpose/thinking-framework-skills
Skill Claude CodeCodex
Runs a Complexity Domain Sort, sorting a situation into Clear, Complicated, Complex, Chaotic, or Confusion and choosing the response posture that fits, caveat-first. It leads with the weak evidence (the 2021 PMC internal-medicine review found scientific proof of its validity has yet to be provided), then forces the…

Skill Claude CodeCodex
Builds a concept map - a non-hierarchical network of concept nodes joined by directed, labeled linking phrases so each node-link-node reads as an explicit proposition, with cross-links across clusters - then surfaces gaps, missing links, and questionable propositions. Use when a domain has many interrelated concepts…

Skill Claude CodeCodex
Produces a known-unknowns ledger by enumerating the relevant evidence not in hand, the variables that bear on a judgment but are unknown or unobservable, rating each unknown by its bearing and its obtainability, then re-rating confidence against the mapped gap. Use when a consequential one-off judgment rests on thin…
product-on-purpose/thinking-framework-skills
Skill Claude CodeCodex
Converts a stuck trade-off into a contradiction to dissolve rather than a compromise to settle for. Names the two conflicting requirements, states an implementation-free Ideal Final Result, and applies the four separation principles (separate the requirements in time, space, scale, or condition) to satisfy both at…
product-on-purpose/thinking-framework-skills
Skill Claude CodeCodex
Produces a both/and polarity map - two interdependent poles, the upside and downside quadrant of each, a greater purpose and a deeper fear, early-warning signs, and action steps - for a chronic tension that should be managed rather than resolved. Use when an organization keeps oscillating destructively between two…
product-on-purpose/thinking-framework-skills
Skill Claude CodeCodex
Produces a decision journal entry that records a consequential decision at the moment it is made - the decision, the rationale, the predicted outcome, an explicit confidence level, and the assumptions it rests on - so it can be honestly reviewed later against what actually happened. Use when committing to a…

Skill Claude CodeCodex
Produces a criteria-weighted option matrix by comparing a set of options against weighted criteria, scoring each, surfacing the explicit tradeoffs, and recommending one while flagging where the scoring is soft. Use when choosing among several real options, or when a decision needs its tradeoffs made explicit rather…
