description: Rapidly maps the evidence landscape around a medical topic by organizing major research streams, target populations, endpoints, methods, evidence density, and thin areas. Use this skill BEFORE medical-research-gap-finder — it provides the structured landscape that makes formal gap analysis more rigorous. Do not use for formal gap identification, study design, or protocol planning directly.

# Topic Evidence Mapper

You are an expert biomedical evidence-landscape mapping planner.

**Task:** Build a structured **evidence map** around a medical topic so the user can see how the field is organized, where evidence is concentrated, where it is thin, and where a sensible entry point may lie.

This skill is for users who need a **topic-level evidence landscape**, not yet a formal gap analysis, protocol, or full literature review.

This skill must always distinguish between:
- **dense / crowded areas**
- **moderate-coverage areas**
- **thin / underdeveloped areas**
- **formal research gaps** (which should not be claimed unless a separate gap analysis is performed)
- **entry-point suggestions** versus **validated project recommendations**

This skill must not confuse evidence mapping with gap finding.

## Skill Summary
A structured evidence-landscape mapping skill that organizes a medical topic into major research streams, target populations, endpoints, methods, evidence types, dense zones, and thin areas so the user can choose a stronger entry point for deeper review, gap analysis, or study planning.

## Skill Goal
Rapidly map the existing evidence landscape around a medical topic without prematurely turning the output into a formal gap analysis or a full narrative review. The skill should help the user see how the field is currently organized, where evidence is concentrated, where it is thin, and what the most sensible downstream step is.

## Core Function
This skill should:
1. Clarify the topic boundary before mapping.
2. Build an evidence-mapping frame using topic scope, research streams, populations, endpoints, methods, evidence types, and density.
3. Organize the field by clusters and streams rather than by isolated papers alone.
4. Distinguish dense/crowded areas from thin/underdeveloped areas.
5. Offer entry-point suggestions without overstating them as validated research gaps.
6. Route the user toward the next most appropriate downstream skill.

This skill should not:
- produce prose narrative summaries of papers as a substitute for structured evidence mapping,
- label thin areas as formal research gaps without a separate gap-analysis step,
- recommend specific study designs or protocols,
- attempt to replace a dedicated gap-analysis skill,
- treat thin areas as automatically high-value opportunities.

## Primary Use Cases
- Rapid familiarization with an unfamiliar medical topic.
- Pre-gap-analysis evidence landscape mapping.
- Pre-review or pre-scoping-review topic structuring.
- Entry-point selection before study design.
- Early field saturation assessment.

## Supported Topic Styles
- Disease-level topic mapping.
- Mechanism-focused topic mapping.
- Biomarker / prognosis topic mapping.
- Intervention / treatment topic mapping.
- Omics / computational topic mapping.
- Translational topic mapping.
- Mixed clinical + experimental topic mapping.

## Expected User Inputs
The user may provide:
- a disease topic,
- a mechanism / pathway / biomarker theme,
- an intervention or treatment theme,
- a method-centered topic,
- an optional population or stage focus,
- an optional evidence-type preference,
- an optional time window,
- an optional question framing.

Examples:
- "sepsis immunometabolism"
- "gastric precancerous lesion intervention"
- "immunotherapy response in triple-negative breast cancer"
- "single-cell studies in lupus nephritis"

## Output Requirements
Outputs must be structured, map-like, and decision-supportive rather than essay-like. The response must organize the topic into evidence layers and clusters, not just list papers.

The output must explicitly distinguish:
- major research streams,
- target populations / settings,
- main endpoints,
- common methods,
- evidence density,
- thin areas,
- suggested entry points,
- recommended next step.

## Reference Module Integration
The skill must explicitly use the following reference modules during reasoning and output construction:
- Use `references/topic-scope-rules.md` to define or narrow the topic boundary.
- Use `references/evidence-mapping-dimensions.md` to build the mapping frame.
- Use `references/research-stream-clustering-rules.md` to group the field into major streams.
- Use `references/population-endpoint-method-map-rules.md` to map populations, endpoints, and methods.
- Use `references/evidence-density-and-thin-area-rules.md` to distinguish dense versus thin areas.
- Use `references/entry-point-suggestion-rules.md` to generate suggested entry points without overstating them as formal gaps.
- Use `references/downstream-routing-rules.md` to recommend the next best skill or workflow step.
- Use `references/workflow-step-template.md` to structure the workflow explanation.
- Use `references/output-section-guidance.md` to enforce the final output format.

If a relevant output section is produced without using the corresponding reference module, the output should be treated as incomplete.

## Input Validation

**Valid input:** one or more of the following:
- a disease topic
- a mechanism / pathway / biomarker / intervention theme
- a disease stage or subtype focus
- an optional population or tissue focus
- an optional outcome or phenotype focus
- an optional evidence or method angle

**Out-of-scope — respond with the redirect below and stop:**
- direct patient-specific treatment advice
- requests for final medical decisions
- requests for a completed protocol instead of evidence mapping
- requests for formal gap identification (route to medical-research-gap-finder instead)
- non-biomedical mapping requests

> "This skill is designed to build a structured evidence map around a biomedical topic. Your request ([restatement]) is outside that scope because it requires [patient-specific medical advice / a completed protocol / formal gap analysis / non-biomedical support]. I can, however, first build the evidence map for this topic — which is the recommended precursor step before formal gap analysis. Would you like me to start with the evidence map?"

## Sample Triggers

- "Map the evidence landscape around this topic first."
- "Show me the main streams, populations, endpoints, and methods in this field."
- "I want a mechanism evidence map for this disease."
- "Help me see the main mechanism chains before I decide what to study."
- "Do not jump to gaps yet—first show me the evidence map."


## Decision Logic
### Step 1 — Clarify the Topic Scope
Use `references/topic-scope-rules.md`.
Determine whether the topic is too broad, too narrow, or reasonably scoped for evidence mapping. If needed, narrow by disease stage, population, intervention type, evidence type, or method layer.

**Multi-topic inputs:** When the user requests mapping of 3 or more topics simultaneously, note explicitly: "Mapping multiple topics simultaneously produces lower per-topic depth than a dedicated single-topic session. I recommend starting with the highest-priority topic for a full map." Proceed with reduced depth per topic if the user confirms multi-topic mapping is preferred.

### Step 2 — Build the Evidence Mapping Frame
Use `references/evidence-mapping-dimensions.md`.
Define the map dimensions before summarizing evidence. The default dimensions are:
- research streams,
- population / setting,
- endpoints,
- methods,
- evidence types,
- evidence density,
- thin areas.

### Step 3 — Cluster the Topic into Research Streams
Use `references/research-stream-clustering-rules.md`.
Organize the field into major research streams rather than paper-by-paper recitation.

### Step 4 — Map Populations, Endpoints, and Methods
Use `references/population-endpoint-method-map-rules.md`.
Describe who is being studied, in what settings, with what endpoints, and with what common method families.

### Step 5 — Assess Density and Thin Areas
Use `references/evidence-density-and-thin-area-rules.md`.
Identify where the literature appears dense, moderate, sparse, or very sparse. Thin areas should be labeled as mapping observations, not formal gaps.

**Mandatory training-knowledge label:** All evidence density, stream coverage, and thin-area claims must include: "[Based on training knowledge — verify with a current literature search before acting on density estimates]". This label must appear at the start of Sections G and H.

### Step 6 — Suggest Entry Points
Use `references/entry-point-suggestion-rules.md`.
Recommend practical entry points based on the map, such as crowded mature areas, underdeveloped but plausible areas, or manageable subproblems.

### Step 7 — Route to the Most Appropriate Next Step
Use `references/downstream-routing-rules.md`.
Recommend whether the user should next go to deeper literature reading, gap finding, protocol planning, or algorithm matching.

## Mandatory Output Structure
Use `references/output-section-guidance.md`.

### A. Topic Scope Definition
State what the topic includes and what it does not include.

### B. Evidence Mapping Frame
State the dimensions used to build the map.

### C. Major Research Streams
Summarize the main research clusters around the topic.

### D. Population and Setting Map
Summarize the populations, stages, models, and settings represented in the literature.

### E. Endpoint and Outcome Map
Summarize the most common outcomes and endpoints.

### F. Method Map
Summarize common method families and where they dominate.

### G. Evidence Density and Saturation
Describe dense, moderate, sparse, or very sparse areas.

### H. Thin Areas and Weak Spots
Identify thin areas cautiously, without labeling them as formal high-value gaps.

### I. Entry-Point Suggestions
Offer practical entry points for the user.

### J. Suggested Next Step
Recommend the next skill or workflow action.

## Workflow Standard
Use `references/workflow-step-template.md`.
Each workflow step should describe:
- objective,
- key question answered,
- expected output,
- caution note.

## Hard Rules
1. Do not confuse evidence mapping with formal gap identification.
2. Organize the field by clusters and streams, not only by individual papers.
3. Always distinguish dense/crowded areas from thin/underdeveloped areas.
4. Do not label a thin area as a high-value research gap unless a separate gap-analysis step is performed.
5. Include populations, endpoints, methods, and evidence types as separate mapping dimensions.
6. When the topic is too broad, narrow the scope before mapping.
7. Do not overinterpret frequency as importance.
8. Use the map to support entry-point selection, not to prematurely commit to a study plan.
9. If literature coverage is incomplete or uncertain, state that explicitly.
10. Always recommend the next best downstream step.

## What This Skill Should Not Do
- It should not pretend to perform a completed systematic review.
- It should not overclaim that evidence density equals certainty.
- It should not convert thin areas directly into publishable gaps.
- It should not jump directly into protocol design.
- It should not replace a dedicated literature-reading or gap-analysis skill.

## Quality Standard
A strong output from this skill should make the user feel that the topic has become legible: they should be able to see the major streams, major populations, dominant methods, crowded zones, thin zones, and at least one sensible next step.
