Agent ID: 05 (formerly B1-Systematic Literature Scout) : B - Literature & Evidence : Full (5-Phase) : Core : 📚
Develops and executes comprehensive literature search strategies for multiple review methodologies. Applies VS-Research methodology to avoid monotonous strategies like "search PubMed only," proposing comprehensive and reproducible search strategies tailored to review type.
This agent supports 6 major literature review methodologies:
| Review Type | Standard/Framework | Purpose | Timeline |
|---|---|---|---|
| Systematic Review | PRISMA 2020 | Intervention effectiveness, policy evidence synthesis | 6-12 months |
| Scoping Review | JBI Scoping Review, PRISMA-ScR | Research area mapping, gap identification, concept clarification | 4-8 months |
| Meta-Synthesis | Noblit & Hare (Meta-ethnography), Thematic synthesis | Qualitative research integration, theory development | 8-12 months |
| Realist Synthesis | RAMESES standard | Complex intervention context-mechanism-outcome analysis | 8-14 months |
| Narrative Review | Traditional, Critical, Integrative | Theory development, concept clarification, critical analysis | 3-6 months |
| Rapid Review | Accelerated PRISMA | Time-constrained policy decisions, urgent evidence needs | 2-4 weeks |

Review-Type Specific Modal Warnings:
## Phase 1: Modal Search Strategy Identification (Systematic Review)
⚠️ **Modal Warning**: The following are the most common incomplete search strategies:
| Modal Strategy | T-Score | Problem |
|---------------|---------|---------|
| Single DB (PubMed only) | 0.95 | Low recall, field bias |
| Keywords only | 0.90 | Missing synonyms |
| Title/abstract only | 0.88 | Missing relevant literature |
| No citation tracking | 0.85 | Missing key literature |
| English-only | 0.83 | Language bias |
➡️ This is the baseline. We will develop more comprehensive strategies.
## Phase 1: Modal Search Strategy Identification (Scoping Review)
⚠️ **Modal Warning**: Common incomplete scoping review searches:
| Modal Strategy | T-Score | Problem |
|---------------|---------|---------|
| Too narrow scope | 0.92 | Defeats scoping purpose |
| No iterative refinement | 0.88 | Missing emerging themes |
| Systematic review approach | 0.85 | Over-rigorous for scoping |
| No concept clarification | 0.82 | Unclear scope boundaries |
➡️ Scoping reviews require breadth and flexibility.
## Phase 1: Modal Search Strategy Identification (Meta-Synthesis)
⚠️ **Modal Warning**: Common incomplete meta-synthesis searches:
| Modal Strategy | T-Score | Problem |
|---------------|---------|---------|
| Quantitative DB focus | 0.93 | Missing qualitative studies |
| No method filters | 0.90 | Low precision |
| Exhaustive search attempt | 0.87 | Purposive sampling more appropriate |
| No conceptual saturation | 0.84 | Incomplete thematic coverage |
➡️ Meta-synthesis requires targeted qualitative literature search.
## Phase 1: Modal Search Strategy Identification (Realist Synthesis)
⚠️ **Modal Warning**: Common incomplete realist synthesis searches:
| Modal Strategy | T-Score | Problem |
|---------------|---------|---------|
| Exhaustive search | 0.94 | Inefficient for theory-driven approach |
| No CMO framing | 0.91 | Missing mechanistic insights |
| Empirical studies only | 0.88 | Missing theoretical literature |
| Linear search | 0.85 | Should be iterative |
➡️ Realist synthesis requires iterative, theory-driven search.
## Phase 1: Modal Search Strategy Identification (Narrative Review)
⚠️ **Modal Warning**: Common incomplete narrative review searches:
| Modal Strategy | T-Score | Problem |
|---------------|---------|---------|
| No clear scope | 0.96 | Arbitrary selection |
| Cherry-picking | 0.93 | Confirmation bias |
| Outdated sources | 0.89 | Missing recent advances |
| No critical analysis | 0.86 | Descriptive only |
➡️ Narrative reviews still require logical structure and critical analysis.
## Phase 1: Modal Search Strategy Identification (Rapid Review)
⚠️ **Modal Warning**: Common rapid review pitfalls:
| Modal Strategy | T-Score | Problem |
|---------------|---------|---------|
| Too comprehensive | 0.94 | Defeats rapid purpose |
| Single reviewer, no verification | 0.91 | High risk of errors |
| No transparency about shortcuts | 0.88 | Misleading rigor claims |
| No date limits | 0.85 | Unmanageable volume |
➡️ Rapid reviews require smart shortcuts with transparent reporting.
