# PHASE 0: Input Validation

## Step 0.0: Detect Input Type

Quick-classify `$ARGUMENTS`:
- Starts with `http://` or `https://` → jump to **Add to Index** (end of file)
- Path exists as local file → jump to **Add to Index** (end of file)
- Everything else (including empty) → continue below as research topic

## Step 0.1: Check Topic

If no topic provided, ask:
> What topic would you like me to research? Examples:
> - "Claude Code hooks best practices"
> - "React state management 2025"
> - "MCP server authentication patterns"

## Step 0.2: Detect Category

> **Reference**: See `${CLAUDE_PLUGIN_ROOT}/docs/extending/research-methodology.md` section "Category Detection Keywords" for full keyword-to-category mapping table.

## Step 0.3: Generate Filename

1. Count existing files in `$JAAN_OUTPUTS_DIR/research/` matching pattern `[0-9][0-9]-*.md`
2. Next number = count + 1 (pad to 2 digits)
3. Slugify topic: lowercase, replace spaces with hyphens, remove special chars
4. Format: `{NN}-{category}-{slug}.md`
5. Path: `$JAAN_OUTPUTS_DIR/research/{filename}`

**Show user:**
> **Research Setup**
> - Topic: {topic}
> - Category: {category}
> - Filename: {filename}
> - Path: $JAAN_OUTPUTS_DIR/research/{filename}

---

# PHASE 1: Clarify & Plan

## Step 1: Clarify Research Scope

**Assess topic clarity:**
- Is the topic specific enough? (e.g., "React" → too broad, "React Server Components" → specific)
- Does it have clear boundaries?
- Is the intent clear (learning, comparison, implementation)?

**If topic is unclear or broad, ask 3-5 clarifying questions.**

> **Reference**: See `${CLAUDE_PLUGIN_ROOT}/docs/extending/pm-research-about-reference.md` section "Clarifying Questions Template" for the full Q1-Q5 question format with options and recommendations.

**Skip questions if:**
- Topic is already specific (e.g., "Claude Code hooks for pre-commit validation")
- User provided context with the topic
- Topic is a well-defined term or technology

**After clarifications, confirm refined topic:**
> "I'll research: {refined topic with specifics}"
> "Focus: {selected options summary}"

## Step 1.5: Choose Research Size

> **Reference**: See `${CLAUDE_PLUGIN_ROOT}/docs/extending/pm-research-about-reference.md` section "Research Size Options" for the size selection table (Quick/Standard/Deep/Extensive/Exhaustive) with source counts and agent allocations.

**Default**: Standard (60) if user doesn't specify or just presses enter.

> **Reference**: See `${CLAUDE_PLUGIN_ROOT}/docs/extending/research-methodology.md` section "Agent Capacity Model" for capacity formula, workload-per-wave tables, and derived agent counts.

**Confirm selection:**
> "Research size: {selected} (~{N} sources, {M} agents)"

## Step 1.6: Choose Approval Mode

> **Reference**: See `${CLAUDE_PLUGIN_ROOT}/docs/extending/pm-research-about-reference.md` section "Approval Mode Options" for the mode selection table (Auto/Summary/Interactive).

**Default**: Interactive (C) if user doesn't specify.

> **Reference**: See `${CLAUDE_PLUGIN_ROOT}/docs/extending/research-methodology.md` section "Approval Mode Behaviors" for the full mode behavior matrix.

**If Auto or Summary selected:**
> "Auto mode enabled. Will show final document for review before writing."

**Store selection as `{approval_mode}` for use in later steps.**

## Step 2: Plan Initial Research Strategy

ultrathink

Plan the **Scout Agent** (Wave 1) approach only:

1. **Identify 3-5 high-level aspects** of the topic
2. **Create broad queries** covering fundamentals, recent developments, and comparisons
3. **Target diverse source types** (official docs, expert blogs, research)

**Scout Agent Assignment:**
- Focus: Broad overview of {topic}
- Queries: 5-8 broad searches covering multiple aspects
- Goal: Map the landscape, identify key subtopics, find authoritative sources

**DO NOT plan Wave 2-3 queries yet** - they will be determined by Scout results.

> **Reference**: See `${CLAUDE_PLUGIN_ROOT}/docs/extending/research-methodology.md` section "Wave Distribution by Size" for agent-per-wave allocation table.

**Output initial plan:**

> **Reference**: See `${CLAUDE_PLUGIN_ROOT}/docs/extending/research-methodology.md` section "Research Plan Display Template" for the display format.

# PHASE 2: Adaptive Wave Research

## Step 3: Wave 1 - Scout Research

Launch **1 Scout Agent** to map the research landscape.

**W1 Workload:** 8 searches + 3 WebFetch = 11 ops (all sizes)

> **Reference**: See `${CLAUDE_PLUGIN_ROOT}/docs/extending/research-methodology.md` section "Wave Agent Prompt Templates" for the Task prompt format. Use W1 Scout default queries.

Launch 1 Scout agent with `subagent_type: Explore`, `run_in_background: false` (wait for results before Wave 2).

**Collect Scout results.**

**If `{approval_mode}` = Summary:** Show brief status:
> "✓ Wave 1 complete: {N} sources, {subtopics_count} subtopics found"

**Proceed to Wave 2 planning.**

## Step 3.5: Wave 2 - Fill Primary Gaps

ultrathink

Analyze Scout results to identify the **biggest gap**:

1. **What subtopic had weakest coverage?** → Primary gap
2. **What source types are missing?** → Source gap
3. **What questions remain unanswered?** → Knowledge gap

**Wave 2 Focus:** Fill the single biggest gap identified by Scout.

> **Reference**: See `${CLAUDE_PLUGIN_ROOT}/docs/extending/research-methodology.md` section "W2 Workload by Size" for agent/search/fetch counts.

> **Reference**: See `${CLAUDE_PLUGIN_ROOT}/docs/extending/research-methodology.md` section "Wave Agent Prompt Templates" (W2 Gaps row).

Launch agent(s) with `subagent_type: Explore`, `run_in_background: false` (wait to analyze before Wave 3).

**Collect Wave 2 results.**

**If `{approval_mode}` = Summary:** Show brief status:
> "✓ Wave 2 complete: {N} sources, gap '{primary_gap}' filled"

**Proceed to Wave 3 planning.**

## Step 3.6: Wave 3 - Expand Coverage

ultrathink

Analyze Scout + Wave 2 results:

1. **Coverage so far** - {current_sources} of {target_sources}
2. **New gaps from Wave 2** - What did Wave 2 reveal?
3. **Subtopics needing expansion** - Which areas need more depth?

**Wave 3 Focus:** Expand into new areas based on Wave 2 discoveries.

> **Reference**: See `${CLAUDE_PLUGIN_ROOT}/docs/extending/research-methodology.md` section "W3 Workload by Size" for agent/search/fetch counts.

> **Reference**: See `${CLAUDE_PLUGIN_ROOT}/docs/extending/research-methodology.md` section "Wave Agent Prompt Templates" (W3 Expand row).

Launch Wave 3 agents with `subagent_type: Explore`, `run_in_background: true`.

**Launch Wave 3 agents in parallel, then collect with TaskOutput.**

**If `{approval_mode}` = Summary:** Show brief status:
> "✓ Wave 3 complete: {N} sources, expanded {areas}"

## Step 3.7: Wave 4 - Verify & Cross-Reference (if size ≥ 60)

**Skip Wave 4 if size = 20.**

ultrathink

Analyze Waves 1-3 results:

1. **Conflicting information** - Which findings disagree?
2. **Unverified claims** - What needs confirmation?
3. **Missing perspectives** - Expert opinions, case studies?

**Wave 4 Focus:** Verify key claims and resolve conflicts.

> **Reference**: See `${CLAUDE_PLUGIN_ROOT}/docs/extending/research-methodology.md` section "W4 Workload by Size" for agent/search/fetch counts.

> **Reference**: See `${CLAUDE_PLUGIN_ROOT}/docs/extending/research-methodology.md` section "Wave Agent Prompt Templates" (W4 Verify row).

Launch Wave 4 agents with `subagent_type: Explore`, `run_in_background: true`.

**Launch Wave 4 agents in parallel, then collect with TaskOutput.**

**If `{approval_mode}` = Summary:** Show brief status:
> "✓ Wave 4 complete: {N} sources, verified {claims_count} claims"

## Step 3.8: Wave 5 - Deep Dive Final (if size ≥ 60)

**Skip Wave 5 if size = 20.**

ultrathink

Analyze all previous waves:

1. **Coverage status** - {current_sources} of {target_sources} ({percentage}%)
2. **Remaining weak areas** - What still needs depth?
3. **Final priorities** - Edge cases, advanced topics, future trends

**Wave 5 Focus:** Final deep dive on remaining priorities.

> **Reference**: See `${CLAUDE_PLUGIN_ROOT}/docs/extending/research-methodology.md` section "W5 Workload by Size" for agent/search/fetch counts.

> **Reference**: See `${CLAUDE_PLUGIN_ROOT}/docs/extending/research-methodology.md` section "Wave Agent Prompt Templates" (W5 Deep row).

Launch Wave 5 agents with `subagent_type: Explore`, `run_in_background: true`.

**Launch Wave 5 agents in parallel, then collect with TaskOutput.**

**If `{approval_mode}` = Summary:** Show brief status:
> "✓ Wave 5 complete: {N} sources, deep dived {areas}"

## Step 4: Consolidate All Wave Results

Merge findings from all completed waves using the summary format from `${CLAUDE_PLUGIN_ROOT}/docs/extending/research-methodology.md` section "Wave Results Summary Template".

**Pre-processing**: Apply hidden character stripping from `${CLAUDE_PLUGIN_ROOT}/docs/extending/threat-scan-reference.md` section "Mandatory Pre-Processing" to all WebFetch content before synthesis.

For consolidation:
1. Combine all findings from all 5 waves
2. Deduplicate sources (same URL → merge)
3. Note confidence levels per finding
4. Mark verified claims (confirmed in Wave 4)
5. Flag any unresolved conflicts

---

# PHASE 3: Synthesis & Planning

## Step 5: Plan Document Structure

ultrathink

Analyze all gathered research and plan the final document:

1. **Executive Summary** - Identify 3-5 most important insights
   - Must be supported by multiple sources
   - Prioritize actionable insights

2. **Subtopic Organization** - Group findings logically
   - Map each finding to a subtopic
   - Ensure no orphan findings

3. **Best Practices** - Extract recommendations
   - Cross-reference across agents
   - Prioritize by source authority

4. **Comparisons** - If relevant
   - Build comparison table from Agent 3 findings

5. **Open Questions** - Note gaps
   - Areas with conflicting info
   - Topics needing deeper research

6. **Source Ranking** - Prioritize references per `${CLAUDE_PLUGIN_ROOT}/docs/extending/research-methodology.md` section "Source Ranking Criteria"

**Output structure plan with source mappings** using the format from `${CLAUDE_PLUGIN_ROOT}/docs/extending/research-methodology.md` section "Document Structure Plan Template".

## Step 6: Merge Findings

1. **Combine all findings** from all agents into unified list
2. **Deduplicate sources:**
   - Same URL → merge descriptions
   - Keep best description
3. **Resolve conflicts:**
   - If sources disagree → note both perspectives
   - Prefer recent over older
   - Prefer official docs over blogs
4. **Cross-reference facts:**
   - Mark findings supported by 2+ sources as "verified"
5. **Calculate totals:**
   - {N} unique sources
   - {N} search queries used
   - {N}% coverage of planned subtopics
