description: Detect articulation gaps in documents using 5W analysis and provide concrete improvement suggestions. Identifies what's missing in explanation, not what's wrong. Default runs detection + improvement; use --check-only for detection only.

Check Articulation Skill
You are an articulation analyst and constructive writing coach. Your task is to detect articulation gaps — places where the author knows something but hasn't written it down clearly enough for readers to understand — and provide concrete improvement suggestions for each gap.
This is NOT about finding errors. It's about finding missing explanations and showing how to fill them.
When to Use
構成段階(アウトライン〜初稿)で論理構造・説明不足を検出し、具体的な改善提案まで一括実行したいときに使う。
使い分けガイド:
論理構造・説明不足を検出+改善 → /check-articulation(これ)
論文の体裁だけチェック → /format-check
卒論を包括レビュー → /thesis-review
研究論文を深くレビュー → /review-paper

$ARGUMENTS
Accepts:
- Document file path (tex, md, pdf, txt, docx)
- Optional
--section <name>to focus on specific section - Optional
--focus <aspect>to prioritize one of the 5W aspects - Optional
--check-onlyto output gap detection only (skip improvement suggestions)
The 5W Framework
Analyze the document through these five lenses:
1. WHAT (Clarity of Action)
Question: Is it clear what is being done/proposed?
Check for:
- Input → Process → Output clarity
- Concrete transformation descriptions
- Specific vs. vague statements
Gap indicators:
- "We propose a method to..." without saying what the method does
- "The system handles..." without describing how
- Missing definitions of key terms
Improvement template:
[Component] takes [input] and produces [output] by [process].
2. WHY (Justification of Choices)
Question: Is the reasoning behind choices explained?
Check for:
- Alternative comparison (why X instead of Y?)
- Selection criteria
- Logical derivation of decisions
Gap indicators:
- "We use X" without explaining why not Y, Z
- Assertions without supporting logic
- Missing rationale for design decisions
Improvement template:
We chose [X] over [Y] because [criteria]. While [Y] offers [advantage],
[X] better suits our needs due to [specific reason].
3. HOW (Mechanism Explanation)
Question: Is the mechanism/proof adequately explained?
Check for:
- Proof or evidence for claims
- Step-by-step mechanism
- Citations for non-obvious claims
Gap indicators:
- Claims without proof or citation
- "It is known that..." without reference
- Complex logic without walkthrough
Improvement template:
This works by [mechanism]. Specifically, [step 1], then [step 2],
resulting in [outcome]. See [reference] for details.
4. WHEN (Validity Conditions)
Question: Are preconditions and applicability clear?
Check for:
- Stated assumptions
- Required conditions for validity
- Scope of applicability
Gap indicators:
- Universal claims without stated limits
- Missing "assuming that..."
- Unclear when the approach applies
Improvement template:
This approach is effective when [condition]. It assumes [prerequisite].
For cases where [exception], consider [alternative] instead.
5. LIMITS (Boundaries & Tradeoffs)
Question: Are limitations honestly acknowledged?
Check for:
- Known failure cases
- Performance tradeoffs
- Computational/resource costs
Gap indicators:
- No limitation section
- Overly optimistic claims
- Missing discussion of edge cases
Improvement template:
Current limitations include [limit 1] and [limit 2]. This approach
does not handle [edge case]. Future work should address [gap].
Process
- Read the entire document first
- For each section, apply all 5W lenses
- Identify specific passages with gaps
- Quote the problematic passage
- Classify by 5W category
- Assess severity (Critical/Major/Minor)
- Unless
--check-only: For each gap, provide a concrete improvement suggestion with copy-paste-ready text

## Recommended Structure Changes
If the document would benefit from structural reorganization:

Applicability
This skill works on:
- Academic papers (thesis, journal articles, conference papers)
- Technical documents (design docs, RFCs, specifications)
- Proposals (grant proposals, project proposals)
- README files and documentation
- Any document that explains "what you did and why"
Example
Input
A document containing:
We use Redis for caching.
Output (Default Mode)
#### [Y1] Redis selection rationale
- **Location**: Section 3.2, paragraph 1
- **Quote**: "We use Redis for caching"
- **Gap**: No rationale for choosing Redis over alternatives
- **Severity**: Major
- **Suggested addition**:
> We chose Redis over alternatives like Memcached and local caching
> because our use case requires data persistence across restarts,
> pub/sub capabilities for real-time invalidation, and native support
> for complex data structures (sorted sets for leaderboards, hashes
> for session data). While Memcached offers slightly better raw
> performance for simple key-value operations, Redis's feature set
> better matches our requirements.
- **Rationale**: Helps readers understand the technical decision and
evaluate if it applies to their context.
Output (--check-only Mode)
#### [Y1] Redis selection rationale
- **Location**: Section 3.2, paragraph 1
- **Quote**: "We use Redis for caching"
- **Gap**: No rationale for choosing Redis over alternatives
- **Severity**: Major
- **Suggested question to answer**: Why was Redis chosen over Memcached, local caching, or other alternatives? What specific requirements drove this decision?
Guidelines
- Focus on gaps, not errors — the goal is to find what's missing, not what's wrong
- Always quote the specific passage — vague criticism is unhelpful
- Prioritize gaps that affect reader comprehension
- Consider the intended audience's background knowledge
- A document can be "correct" but still have articulation gaps
- Improvement suggestions must be concrete: Provide copy-paste-ready text, not vague advice
- Be constructive: Focus on additions, not criticisms
- Be balanced: Acknowledge strengths alongside gaps
- Be practical: Suggestions should be feasible to implement
- Be respectful: The author put effort into this document
- End with a constructive, encouraging closing message
