Medical Topic Saturation and Whitespace Checker

Use the reference modules as follows:

• references/topic-unit-framework.md → use when defining the exact topic unit in Section A.
• references/saturation-signal-framework.md → use when identifying crowding, field occupancy, repetitive study patterns, and claim congestion in Sections B–D.
• references/whitespace-rules.md → use when identifying meaningful open space and rejecting cosmetic novelty in Sections C–F.
• references/differentiation-angle-framework.md → use when constructing viable entry angles in Sections E–G.
• references/timing-window-framework.md → use when judging whether the field window is open, narrowing, or nearly closed in Sections D–G.
• references/evidence-strength-audit.md → use when checking whether “saturation” claims are supported by real evidence depth rather than discussion volume alone in Sections B–E.
• references/output-section-guidance.md → use as the section-level formatting and content control standard for Sections A–I.

If the output does not visibly reflect these modules, the result should be treated as incomplete.

Input Validation

Valid input: [biomedical topic / disease-topic pair / method-topic pair / biomarker direction / target-pathway area] + [request to assess saturation / crowding / remaining whitespace / timing window / whether it is still worth entering]

Optional additions:

• disease stage or population constraints
• modality or platform constraints
• endpoint or use-case framing
• translational emphasis
• resource constraints
• publication goal or project horizon
• anchor papers or competing directions

Examples:

• “Is the ferroptosis prognostic-signature space in ccRCC already saturated?”
• “Assess whether blood-based biomarkers for immunotherapy response in NSCLC are too crowded now.”
• “Is spatial transcriptomics in IBD still open for differentiated entry?”
• “Check whether STING-pathway resistance work in melanoma is already over-occupied.”

Out-of-scope — respond with the redirect below and stop:

• personal career advice without a defined research topic
• patient-specific treatment or diagnostic recommendations
• market sizing or company investment advice unrelated to research-topic saturation
• unsupported claims that a topic is “dead,” “solved,” or “guaranteed publishable” without retrieved evidence

“This skill assesses biomedical research-topic saturation and remaining whitespace at the field level. Your request ([restatement]) requires personal, patient-specific, or unsupported predictive guidance, which is outside its scope.”

Sample Triggers

• “Is this topic already too crowded to start?”
• “Has this disease-mechanism space already been overworked?”
• “Is there still a publication window here?”
• “Are there still real differentiating angles left in this hotspot?”
• “Is this field truly saturated or just noisy?”
• “Would entering this topic now be late, or still worthwhile?”

Core Function

This skill should:

1. define the exact topic unit under review,
2. retrieve and organize field-occupancy signals,
3. distinguish popularity from true saturation,
4. identify repeated study templates and claim congestion,
5. separate meaningful whitespace from cosmetic variation,
6. assess timing window and entry feasibility,
7. recommend whether to enter, narrow, delay, or avoid the topic,
8. identify the most viable differentiated entry angle if one still exists.

This skill should not:

• treat publication count alone as saturation,
• confuse trendiness with field closure,
• call trivial re-framing “whitespace,”
• assume that an underexplored topic is automatically valuable,
• ignore evidence quality, validation depth, or translational relevance,
• present a broad impression as if it were an evidence-backed field audit.

Execution — 8 Steps (always run in order)

Step 1 — Define the Topic Unit Precisely

Identify and restate:

• disease / condition / research area,
• specific topic unit,
• population / stage / setting,
• modality / platform / assay / method,
• endpoint or use-case context,
• translational position,
• and whether the user wants a broad-area scan or a narrow entry-angle judgment.

If the topic is too broad, narrow it before formal assessment. State assumptions explicitly.

Step 2 — Retrieve Topic-Occupancy Literature and Signals

Retrieve literature and evidence signals focused on the exact topic unit before formal judgment.

Prioritize:

1. peer-reviewed biomedical literature and major reviews for field structure,
2. recent original studies for repeated designs, competitive clustering, and validation patterns,
3. clearly labeled preprints only as supplementary recency signals,
4. major consortia/guidelines only when relevant to real field embedding or closure.

Do not claim saturation from title density alone. Use abstract/full-text-level evidence where possible.

Step 3 — Build the Saturation Signal Map

Extract signals such as:

• repeated study designs,
• repeated disease-feature combinations,
• repeated signatures or model templates,
• concentration around major teams or recurring groups,
• benchmark congestion,
• limited room for first-position claims,
• strong versus shallow validation patterns,
• and translational crowding versus exploratory noise.

Keep signals structured rather than narrative.

Step 4 — Distinguish True Saturation from Superficial Crowding

Separate:

• many papers with weak repetition,
• many papers with real validation depth,
• strategically occupied but not numerically huge spaces,
• loud but still low-evidence spaces,
• and fields where the obvious entry points are already closed.

Do not confuse hype, visibility, and field closure.

Step 5 — Detect Meaningful Whitespace

Look for remaining open angles such as:

• understudied populations or stages,
• cleaner endpoints,
• stronger validation designs,
• orthogonal or better-matched datasets,
• clinically more meaningful framing,
• comparator gaps,
• mechanism-to-translation bridges,
• implementation-relevant follow-up,
• or methodological upgrades that change the claim quality rather than just the toolset.

Whitespace must be meaningful, not cosmetic.

Step 6 — Assess Timing Window and Entry Feasibility

Judge whether the field window is:

• open,
• narrowing,
• late but still differentiable,
• or nearly closed.

Then assess whether the remaining angle is realistically actionable under likely constraints:

• data or cohort access,
• assay or experimental burden,
• validation burden,
• method complexity,
• team capability,
• timeline,
• and publication competitiveness.

Step 7 — Prioritize Entry Options

Identify:

• saturated areas that should be avoided,
• crowded but still viable subspaces,
• under-validated but still high-value openings,
• late-entry options that only work with stronger resources,
• and the most credible differentiated entry path.

Step 8 — Perform Self-Critical Review

Before finalizing, check:

• whether popularity was mistaken for saturation,
• whether “whitespace” was actually only cosmetic novelty,
• whether timing judgment depended too heavily on recency impressions,
• whether major-group occupancy was overstated,
• whether the recommended entry angle is genuinely differentiated,
• and whether the final recommendation is truly supported by the retrieved evidence.

Mandatory Output Structure

A. Topic Framing

• topic under review
• exact topic unit
• scan objective
• scope boundaries
• assumptions made

B. Retrieval and Evidence Audit

• retrieval scope and source types
• approximate evidence composition
• what was included vs excluded
• field-density overview by subarea

C. Structured Saturation Signal Map

Provide a table-first map organized by the major saturation dimensions.

For each row include:

• saturation dimension
• observed pattern
• why it suggests crowding or non-crowding
• evidence depth
• confidence notes

Recommended dimensions:

• publication density
• repeated study-template density
• validation depth
• major-group occupancy
• comparator congestion
• translational occupancy
• first-position claim availability

D. True Saturation vs Superficial Crowding Summary

Summarize:

• which parts of the field are truly saturated,
• which are noisy but shallow,
• which are strategically occupied despite limited volume,
• and where the obvious claims are already closed.

E. Whitespace and Differentiation Map

Provide a table-first map of remaining entry angles.

For each row include:

• remaining angle
• why it is still open
• why it is not just cosmetic novelty
• feasibility level
• validation burden
• main risk

F. Timing Window and Entry Feasibility Summary

Summarize:

• whether the window is open, narrowing, late-but-possible, or nearly closed,
• what evidence supports that timing judgment,
• what minimum conditions would still make entry worthwhile,
• and what would make the topic too late to enter.

G. Primary Recommended Entry Direction

Recommend one primary next-step direction and explain:

• why this entry angle is more viable than alternatives,
• what evidence supports it,
• what minimum scope should be used first,
• what differentiation must be preserved,
• and what the main failure risk is.

H. Self-Critical Risk Review

Include:

• strongest part of the saturation map,
• most assumption-dependent part,
• most likely overcalled crowding signal,
• easiest-to-overstate whitespace,
• likely reviewer criticism,
• fallback interpretation if the recommended entry angle proves less open than expected.

I. Retrieved and Verified References

List the retrieved references used for the scan.

Reference rules:

• do not fabricate citations,
• do not claim field occupancy, timing closure, or competitive dominance without support,
• separate peer-reviewed evidence from preprints if both are used,
• when the evidence for saturation is indirect, say so explicitly.

Formatting Expectations

• Use a table-first output, not a long narrative trend note.
• Prefer explicit saturation labels and compact evidence statements.
• Always distinguish popularity, saturation, validation depth, and remaining whitespace.
• Do not merge “crowded” and “mature” unless the evidence genuinely supports both.
• When the space is broad, group subareas into meaningful clusters instead of giving a flat, noisy summary.

Hard Rules

1. Never treat publication volume alone as proof of saturation.
2. Always distinguish popularity from true field closure.
3. Always distinguish meaningful whitespace from cosmetic novelty.
4. Do not call a topic open just because a minor variation has not yet been published.
5. Validation depth matters more than trend visibility.
6. A topic is not strategically open just because many existing studies are weak.
7. When field signals conflict, represent the conflict directly instead of forcing a single clean narrative.
8. If major groups or repeated designs have already occupied the obvious claims, state that directly.
9. If the user asks for a broad-area scan, prioritize structure and entry relevance over completeness theater.
10. Always include a self-critical review before final recommendation.
11. Never fabricate references, PMIDs, DOIs, dataset status, field-occupancy claims, timing-window signals, or major-group positioning.
12. When evidence is indirect or uncertain, label the judgment as evidence-limited rather than filling gaps.

What This Skill Should Not Do

This skill should not:

• recommend entering a topic based on excitement alone,
• label a topic saturated without evidence-backed crowding signals,
• confuse novelty theater with genuine whitespace,
• hide weak timing judgments behind confident wording,
• ignore realistic validation burden,
• pretend that all underexplored spaces are worth pursuing.

Quality Standard

A high-quality output from this skill should feel like a topic-entry decision map for biomedical research, not a vague hotspot commentary. The user should come away understanding:

• which parts of the field are truly crowded,
• which still contain meaningful whitespace,
• whether the timing window is still open,
• what the most credible differentiated entry angle is,
• and whether the smartest next step is to enter, narrow, delay, or avoid the topic.
