description: >
Critical thinking: clarify claims, weigh evidence, surface assumptions,
test logic for gaps and fallacies, scan biases, stress-test conclusions.
Use when the user asks for critical thinking, a belief or argument audit,
decision-quality review, devil's advocate, steel/straw man check, bias or
fallacy scan, red-team, "what am I missing", logical stress-test, or
epistemic or confidence calibration. Skip for execution-only tasks with no
evaluative angle.

# Critical Thinking
**Critical thinking** is disciplined inquiry that keeps **description** separate from **evaluation**: surface assumptions, weigh evidence, test logic, consider alternatives, then state a proportionate conclusion. If the conventional view is well-supported, say so — this is inquiry, not contrarianism by default.
- **How to run it with this skill:** one phase per clearly headed section, in the order stated in Setup (default pass unless the user requested otherwise); always close with **Conclusion** (judgment, confidence, falsifiers) unless the user explicitly stops early.
+ **How to run it with this skill:** one phase per clearly headed section, always in this order: Clarify → Information → Assumptions → Reasoning → Alternatives → Conclusion. Always include **Conclusion** unless the user explicitly stops the whole review early.

## Setup (run before starting)
In one short block:
1. **Focus** — the specific claim, proposal, or question under review
- 2. **Default pass** — Clarify → Information → Assumptions → Reasoning → Alternatives → Conclusion (state this line so the user sees the path)
+ 2. **Pass** — Clarify → Information → Assumptions → Reasoning → Alternatives → Conclusion (fixed sequence; state this line once in the setup block so the user sees the path)
If essential context is missing, ask at most 3 questions in one message, then proceed. Note any remaining gaps or working guesses in plain language (no bracket tags in Setup).
- If the user asks to **skip or reorder** phases (e.g. fast logic-only pass), follow their sequence and still end with **Conclusion**.

## The Phases
### Clarify
Restate the target in one precise sentence. Separate **factual** vs **normative** claims. Name success criteria if a decision is involved.
### Information
What evidence exists? Each bullet starts with **`[CITED]`** or **`[MISSING]`**:
- **`[CITED]`** — a traceable basis (user text, repo, doc, link, study, etc.); in the same bullet, name the basis and one line on strength or limits (no extra strength tags).
- **`[MISSING]`** — no traceable basis yet for that point, or evidence was requested but not available.
### Assumptions
List tacit premises. For each: **Assumption:** … — **If false:** …
+ When the **Focus** mixes **is** and **should**, surface **value / normative** premises too (e.g. **Value premise:** … — **If rejected:** …) alongside factual assumptions where it clarifies the chain.
+
### Reasoning
- Trace the argument chain. Flag **leaps**, **circular** patterns, **correlation vs causation**, and **missing steps**. No new factual assertions here — only structure.
+ Trace the argument chain. Flag **leaps**, **circular** patterns, **correlation vs causation**, and **missing steps**. No new factual assertions here — only structure. If a premise is needed but was never established in **Information**, do **not** assert it as true; label it as an **ungrounded premise** (structural gap only). When **values** and **evidence** both do work in the chain, show which links depend on which.
**Bias and fallacy pass (compact):** add a short sub-list — only items that apply; omit the rest rather than padding.
- **Biases to scan:** confirmation; anchoring; survivorship; undue authority; sunk cost — plus any other bias clearly relevant to the case.
- **Fallacies to name if present** (tie each to the chain above): ad hominem; straw man; false dichotomy; slippery slope; hasty generalization; begging the question.
If none apply, state that plainly in one line.
### Alternatives
Credible competing explanations, plans, or frames. Do not collapse into debate rhetoric; keep alternatives plausible.
### Conclusion
- 1. **Judgment** — answer the focus question directly
- 2. **Confidence** — High / Medium / Low with one-line justification tied to how much is `[MISSING]` vs well-supported `[CITED]` evidence
- 3. **What would change my mind** — concrete falsifiers or new data
+ 1. **Judgment** — answer the **Focus** directly; when factual and normative claims were both in play, separate **what follows from the cited evidence** from **what depends on value premises** (short clauses are enough). Close with **one sentence in plain language** on how strong the case is given `[CITED]` vs `[MISSING]` evidence.
+ 2. **What would change the judgment** — concrete falsifiers or new data; phrase relative to the **Focus** (e.g. the claim-holder’s view, a named third party, or *this assessment* when the review is impersonal).

## Execution Rules
1. Run phases in one response unless the user requests step-by-step pacing.
2. Never merge **Information** and **Reasoning** in the same bullet block.
3. Do not smuggle new unsupported facts into **Conclusion**; only synthesize prior phases.
4. If the user is emotionally fused with a position, name it neutrally and continue the phase plan.
5. Be intellectually honest: acknowledge strong opposing evidence and uncertainty where the phases support it.

## Checklist (verify before responding)
- - [ ] Setup block: focus + stated pass (or user-requested variant)
- - [ ] Each phase is its own section, following the order stated in Setup
+ - [ ] Setup block: **Focus** and stated **Pass** (fixed sequence)
+ - [ ] Each phase is its own section in canonical order (Clarify through Conclusion)
- [ ] Information: each bullet starts with `[CITED]` (basis + limits in-bullet) or `[MISSING]`
- - [ ] Assumptions use **Assumption** / **If false** pairs
- - [ ] Reasoning references only what earlier phases established; bias/fallacy pass done or explicitly "none identified"
- - [ ] Conclusion includes judgment, confidence, and falsifiers
+ - [ ] Assumptions use **Assumption** / **If false** pairs; **Value premise** / **If rejected** when the Focus mixes facts and shoulds
+ - [ ] Reasoning references only what earlier phases established; flags **ungrounded premises** where needed; bias/fallacy pass done or explicitly "none identified"
+ - [ ] Conclusion: judgment (evidence vs values when both apply, plus one plain sentence on strength of case from Information), falsifiers phrased for the **Focus**
