If next-session.md exists in the active session directory or current workspace, read it as optional prior-session context.
Always parse the user's task description (required input).
Check if the combined input provides: target file paths, expected changes per file, and BDD-style success criteria.
Apply this heuristic:

Input specificity	Clarify depth	Rationale
All 3 present (files + changes + criteria)	AskUserQuestion only — ask 2-3 binary/choice questions for remaining ambiguities, skip Phases 2-2.5	Prior session retro effectively served as clarify
1-2 present	--light mode — iterative Q&A without sub-agents	Partial clarity, direct questions suffice
None present (vague requirement)	Default mode — full research + expert analysis	Scope is open, exploration needed

This heuristic can be overridden by explicit --light flag or user instruction.

Default Mode

Phase 0: Update Live State

Use the live-state helper for scalar fields, then edit list fields in the resolved live-state file:

bash {CWF_PLUGIN_DIR}/scripts/cwf-live-state.sh set . \
  phase="clarify" \
  task="{requirement summary}"
live_state_file=$(bash {CWF_PLUGIN_DIR}/scripts/cwf-live-state.sh resolve)

Set live.key_files in {live_state_file} to files relevant to the requirement.

Phase 0.5: Resolve Session Directory

Resolve the effective live-state file, then read live.dir before any {session_dir} placeholder use:

live_state_file=$(bash {CWF_PLUGIN_DIR}/scripts/cwf-live-state.sh resolve)
session_dir=$(bash {CWF_PLUGIN_DIR}/scripts/cwf-live-state.sh get . dir)

session_dir: "{live.dir value from resolved live-state file}"

Phase 1: Capture & Decompose

Record the original requirement verbatim
Decompose into concrete decision points — specific questions that need answers before implementation can begin
- Frame as questions, not categories ("Which auth library?" not "Authentication")
- Focus on decisions that affect implementation
Present the decision points to the user before proceeding

## Original Requirement
"{user's original request verbatim}"

## Decision Points
1. {specific question}
2. {specific question}
...

Phase 2: Research

Context recovery (before launching)

Apply the context recovery protocol to these files:

{session_dir}/clarify-codebase-research.md
{session_dir}/clarify-web-research.md

Launch sub-agents simultaneously using the Task tool (only for missing or invalid results).

Shared output persistence contract: agent-patterns.md § Sub-agent Output Persistence Contract.

Sub-agent A: Codebase Researcher

Task tool:
  subagent_type: Explore
  max_turns: 20
  prompt: |
    Read `{SKILL_DIR}/references/research-guide.md` and follow
    **Section 1: Codebase Research** exactly.
    Report evidence only — do not make decisions.

    Decision points:
    {list from Phase 1}

    Write your complete findings to: {session_dir}/clarify-codebase-research.md
    The file MUST exist when you finish. End your output file with the exact
    line `<!-- AGENT_COMPLETE -->` as the last line.

Sub-agent B: Web Researcher

Task tool:
  subagent_type: general-purpose
  max_turns: 20
  prompt: |
    Read `{SKILL_DIR}/references/research-guide.md` and follow
    **Section 2: Web / Best Practice Research** exactly.
    Also follow the "Web Research Protocol" section in
    `{CWF_PLUGIN_DIR}/references/agent-patterns.md` for tool order
    and fallback behavior.
    Report findings only — do not make decisions.

    Decision points:
    {list from Phase 1}

    Write your complete findings to: {session_dir}/clarify-web-research.md
    The file MUST exist when you finish. End your output file with the exact
    line `<!-- AGENT_COMPLETE -->` as the last line.

Both sub-agents run in parallel. Wait for both to complete. Read the output files from session dir (not the in-memory Task return values).

Phase 2.5: Expert Analysis

Context recovery (before launching)

Apply the context recovery protocol to these files:

{session_dir}/clarify-expert-alpha.md
{session_dir}/clarify-expert-beta.md

Launch two domain expert sub-agents simultaneously using the Task tool (only for missing or invalid results).

Expert selection:

Read expert_roster from cwf-state.yaml
Analyze decision points for domain keywords; match against each roster entry's domain field
Select 2 experts with contrasting frameworks — different analytical lenses on the same problem
If roster has < 2 domain matches, fill remaining slots via independent selection (prioritize well-known figures with contrasting methodological approaches)

Expert α

Task tool:
  subagent_type: general-purpose
  max_turns: 12
  prompt: |
    Read {CWF_PLUGIN_DIR}/references/expert-advisor-guide.md.
    You are Expert α, operating in **clarify mode**.

    Your identity: {selected expert name}
    Your framework: {expert's domain from roster or independent selection}

    Decision points:
    {list from Phase 1}

    Research findings summary:
    {summarized outputs from Phase 2 codebase + web research}

    Analyze which decisions are most critical through your published framework.
    Use web search to verify your expert identity and cite published work.
    Output your analysis in the clarify mode format from the guide.

    Write your complete findings to: {session_dir}/clarify-expert-alpha.md
    The file MUST exist when you finish. End your output file with the exact
    line `<!-- AGENT_COMPLETE -->` as the last line.

Expert β

Task tool:
  subagent_type: general-purpose
  max_turns: 12
  prompt: |
    Read {CWF_PLUGIN_DIR}/references/expert-advisor-guide.md.
    You are Expert β, operating in **clarify mode**.

    Your identity: {selected expert name — contrasting framework from Expert α}
    Your framework: {expert's domain from roster or independent selection}

    Decision points:
    {list from Phase 1}

    Research findings summary:
    {summarized outputs from Phase 2 codebase + web research}

    Analyze which decisions are most critical through your published framework.
    Use web search to verify your expert identity and cite published work.
    Output your analysis in the clarify mode format from the guide.

    Write your complete findings to: {session_dir}/clarify-expert-beta.md
    The file MUST exist when you finish. End your output file with the exact
    line `<!-- AGENT_COMPLETE -->` as the last line.

Both expert sub-agents run in parallel. Wait for both to complete. Read the output files from session dir (not the in-memory Task return values).

--light mode: Phase 2.5 is skipped (consistent with --light skipping all sub-agents).

Phase 3: Classify & Decide

Read {SKILL_DIR}/references/aggregation-guide.md for full classification rules.

For each decision point, classify using three evidence sources: codebase research (Phase 2), web research (Phase 2), and expert analysis (Phase 2.5).

T1 (Codebase-resolved) — codebase has clear evidence → decide autonomously, cite files
T2 (Best-practice-resolved) — best practice consensus → decide autonomously, cite sources
T3 (Requires human) — evidence conflicts, all silent, or subjective → queue

Constructive tension: When sources conflict, classify as T3. Expert analysis provides additional signal but does not override direct codebase or best-practice evidence.

Present the classification:

## Agent Decisions (T1 & T2)

| # | Decision Point | Tier | Decision | Evidence |
|---|---------------|------|----------|----------|
| 1 | ... | T1 | ... | file paths |
| 2 | ... | T2 | ... | sources |

## Requires Human Decision (T3)

| # | Decision Point | Reason |
|---|---------------|--------|
| 3 | ... | conflict / no evidence / subjective |

If zero T3 items: Skip Phases 3.5 and 4 entirely. Go to Phase 5.

Phase 3.5: Advisory (T3 only)

Context recovery (before launching)

Apply the context recovery protocol to these files:

{session_dir}/clarify-advisor-alpha.md
{session_dir}/clarify-advisor-beta.md

Launch two advisory sub-agents simultaneously (only for missing or invalid results):

Advisor α

Task tool:
  subagent_type: general-purpose
  model: haiku
  max_turns: 12
  prompt: |
    Read `{SKILL_DIR}/references/advisory-guide.md`. You are Advisor α.

    Tier 3 decision points:
    {list of T3 items}

    Research context:
    {codebase findings for these items}
    {web research findings for these items}

    Argue for the first perspective per the guide's side-assignment rules.

    Write your complete findings to: {session_dir}/clarify-advisor-alpha.md
    The file MUST exist when you finish. End your output file with the exact
    line `<!-- AGENT_COMPLETE -->` as the last line.

Advisor β

Task tool:
  subagent_type: general-purpose
  model: haiku
  max_turns: 12
  prompt: |
    Read `{SKILL_DIR}/references/advisory-guide.md`. You are Advisor β.

    Tier 3 decision points:
    {list of T3 items}

    Research context:
    {codebase findings for these items}
    {web research findings for these items}

    Argue for the opposing perspective per the guide's side-assignment rules.

    Write your complete findings to: {session_dir}/clarify-advisor-beta.md
    The file MUST exist when you finish. End your output file with the exact
    line `<!-- AGENT_COMPLETE -->` as the last line.

Both advisors run in parallel. Wait for both to complete. Read the output files from session dir (not the in-memory Task return values).

Phase 4: Persistent Questioning (T3 only)

Read {SKILL_DIR}/references/questioning-guide.md for full methodology.

For each T3 item, use AskUserQuestion with:

Research context: What codebase and web research found
Advisor α's position: Their argument (brief)
Advisor β's position: Their argument (brief)
The question: With 2-4 concrete options from advisory perspectives

After each answer:

Why-dig 2-3 times on surface-level answers (see questioning-guide.md)
Detect tensions between this answer and previous answers
Check for new ambiguities revealed by the answer → classify → repeat if T3

Phase 5: Output

## Requirement Clarification Summary

### Before (Original)
"{original request verbatim}"

### After (Clarified)
**Goal**: {precise description}
**Scope**: {what is included and excluded}
**Constraints**: {limitations and requirements}

### Expert Analysis
(Only in default mode, omitted in --light)

| Expert | Framework | Key Insight |
|--------|-----------|-------------|
| {Expert α name} | {framework} | {1-line summary of analysis} |
| {Expert β name} | {framework} | {1-line summary of analysis} |

### All Decisions

| # | Decision Point | Decision | Decided By | Evidence |
|---|---------------|----------|------------|----------|
| 1 | ... | ... | Agent (T1) | file paths |
| 2 | ... | ... | Agent (T2) | sources |
| 3 | ... | ... | Human | advisory context |

Save this clarified requirement to a project-appropriate location with a descriptive filename (required).

Completion tracking (after writing the required summary file):

Run: bash {CWF_PLUGIN_DIR}/scripts/cwf-live-state.sh set . clarify_completed_at="{ISO 8601 UTC timestamp}"
Run: bash {CWF_PLUGIN_DIR}/scripts/cwf-live-state.sh set . clarify_result_file="{saved summary file path}"

This state is what cwf:impl Phase 1.0 checks as a pre-condition.

Follow-up suggestions (when CWF plugin is loaded):

cwf:review --mode clarify — Multi-perspective review of the clarified requirement before implementation
cwf:handoff --phase — Generate a phase handoff document that captures HOW context (protocols, rules, must-read references, constraints) for the implementation phase. Recommended when context will be cleared before implementation, as plan.md carries WHAT but not HOW.

Present both suggestions. If context is getting large or the user is about to clear context, emphasize the phase handoff suggestion.

--light Mode

Fast, direct clarification without sub-agents. The original clarify behavior with added persistence.

Phase 1: Capture

Record the requirement verbatim
Identify ambiguities using the categories in questioning-guide.md

Phase 2: Iterative Q&A

Read {SKILL_DIR}/references/questioning-guide.md for methodology.

Loop using AskUserQuestion:

while ambiguities remain:
    pick most critical ambiguity
    ask with 2-4 concrete options
    why-dig on surface-level answers (2-3 levels)
    detect tensions with prior answers
    check for new ambiguities

Phase 3: Output

## Requirement Clarification Summary

### Before (Original)
"{original request verbatim}"

### After (Clarified)
**Goal**: {precise description}
**Reason**: {the ultimate purpose or jobs-to-be-done}
**Scope**: {what is included and excluded}
**Constraints**: {limitations, requirements, preferences}
**Success Criteria**: {how to verify correctness}

### Decisions Made

| Question | Decision |
|----------|----------|
| ... | ... |

Save the summary to a project-appropriate location with a descriptive filename (required).

Completion tracking (after writing the required summary file):

Run: bash {CWF_PLUGIN_DIR}/scripts/cwf-live-state.sh set . clarify_completed_at="{ISO 8601 UTC timestamp}"
Run: bash {CWF_PLUGIN_DIR}/scripts/cwf-live-state.sh set . clarify_result_file="{saved summary file path}"

This state is what cwf:impl Phase 1.0 checks as a pre-condition.

Expert Roster Update (when experts were used in Phase 2.5): Follow the Roster Maintenance procedure in {CWF_PLUGIN_DIR}/references/expert-advisor-guide.md.

Follow-up (when CWF plugin is loaded): Suggest cwf:handoff --phase if the user plans to clear context before implementation.

Rules

Research first, ask later (default mode): Exhaust research before asking
Cite evidence: Every autonomous decision must include specific evidence
Respect the tiers: Do not ask about T1/T2; do not auto-decide T3
Constructive tension: Conflicts between sources are signals, not problems
Persistent but not annoying: Why-dig on vague answers, accept clear ones
Preserve intent: Refine the requirement, don't redirect it
Grounded experts: Best practice research must cite real published work
Honest advisors: Advisory opinions argue in good faith, not strawman
Expert evidence is supplementary: Expert analysis enriches classification but does not override direct codebase or best-practice evidence
