Flow interview

Conduct an extremely thorough interview about a task/spec and write refined details back.

IMPORTANT: This plugin uses .flow/ for ALL task tracking. Do NOT use markdown TODOs, plan files, TodoWrite, or other tracking methods. All task state must be read and written via flowctl.

CRITICAL: flowctl is BUNDLED — NOT installed globally. which flowctl will fail (expected). Always use:

FLOWCTL="${CLAUDE_PLUGIN_ROOT}/scripts/flowctl"
$FLOWCTL <command>

Pre-check: Local setup version

If .flow/meta.json exists and has setup_version, compare to plugin version:

SETUP_VER=$(jq -r '.setup_version // empty' .flow/meta.json 2>/dev/null)
PLUGIN_VER=$(jq -r '.version' "${CLAUDE_PLUGIN_ROOT}/.claude-plugin/plugin.json")
if [[ -n "$SETUP_VER" ]]; then
  [[ "$SETUP_VER" = "$PLUGIN_VER" ]] || echo "Plugin updated to v${PLUGIN_VER}. Run /flow-next:setup to refresh local scripts (current: v${SETUP_VER})."
fi

Continue regardless (non-blocking).

Role: technical interviewer, spec refiner Goal: extract complete implementation details through deep questioning (40+ questions typical)

Input

Full request: $ARGUMENTS

Accepts:

• •Flow epic ID fn-N-xxx (e.g., fn-1-abc) or legacy fn-N: Fetch with flowctl show, write back with flowctl epic set-plan
• •Flow task ID fn-N-xxx.M (e.g., fn-1-abc.2) or legacy fn-N.M: Fetch with flowctl show, write back with flowctl task set-description/set-acceptance
• •File path (e.g., docs/spec.md): Read file, interview, rewrite file
• •Empty: Prompt for target

Examples:

• •/flow-next:interview fn-1-abc
• •/flow-next:interview fn-1-abc.3
• •/flow-next:interview fn-1 (legacy format still supported)
• •/flow-next:interview docs/oauth-spec.md

If empty, ask: "What should I interview you about? Give me a Flow ID (e.g., fn-1-abc) or file path (e.g., docs/spec.md)"

Setup

FLOWCTL="${CLAUDE_PLUGIN_ROOT}/scripts/flowctl"

Detect Input Type

1. •

   Flow epic ID pattern: matches fn-\d+(-[a-z0-9]+)? (e.g., fn-1-abc, fn-12, fn-42-z9k)

   • •Fetch: $FLOWCTL show <id> --json
   • •Read spec: $FLOWCTL cat <id>
2. •

   Flow task ID pattern: matches fn-\d+(-[a-z0-9]+)?\.\d+ (e.g., fn-1-abc.3, fn-12.5)

   • •Fetch: $FLOWCTL show <id> --json
   • •Read spec: $FLOWCTL cat <id>
   • •Also get epic context: $FLOWCTL cat <epic-id>
3. •

   File path: anything else with a path-like structure or .md extension

   • •Read file contents
   • •If file doesn't exist, ask user to provide valid path

Interview Process

CRITICAL REQUIREMENT: You MUST use the AskUserQuestion tool for every question.

• •DO NOT output questions as text
• •DO NOT list questions in your response
• •ONLY ask questions via AskUserQuestion tool calls
• •Group 2-4 related questions per tool call
• •Expect 40+ questions total for complex specs

Anti-pattern (WRONG):

Question 1: What database should we use?
Options: a) PostgreSQL b) SQLite c) MongoDB

Correct pattern: Call AskUserQuestion tool with question and options.

Question Categories

Read questions.md for all question categories and interview guidelines.

NOT in scope (defer to /flow-next:plan)

• •Research scouts (codebase analysis)
• •File/line references
• •Task creation (interview refines requirements, plan creates tasks)
• •Task sizing (S/M/L)
• •Dependency ordering
• •Phased implementation details

Write Refined Spec

After interview complete, write everything back — scope depends on input type.

For NEW IDEA (text input, no Flow ID)

Create epic with interview output. DO NOT create tasks — that's /flow-next:plan's job.

$FLOWCTL epic create --title "..." --json
$FLOWCTL epic set-plan <id> --file - --json <<'EOF'
# Epic Title

## Problem
Clear problem statement

## Key Decisions
Decisions made during interview (e.g., "Use OAuth not SAML", "Support mobile + web")

## Edge Cases
- Edge case 1
- Edge case 2

## Open Questions
Unresolved items that need research during planning

## Acceptance
- [ ] Criterion 1
- [ ] Criterion 2
EOF

Then suggest: "Run /flow-next:plan fn-N to research best practices and create tasks."

For EXISTING EPIC (fn-N that already has tasks)

First check if tasks exist:

$FLOWCTL tasks --epic <id> --json

If tasks exist: Only update the epic spec (add edge cases, clarify requirements). Do NOT touch task specs — plan already created them.

If no tasks: Update epic spec, then suggest /flow-next:plan.

$FLOWCTL epic set-plan <id> --file - --json <<'EOF'
# Epic Title

## Problem
Clear problem statement

## Key Decisions
Decisions made during interview

## Edge Cases
- Edge case 1
- Edge case 2

## Open Questions
Unresolved items

## Acceptance
- [ ] Criterion 1
- [ ] Criterion 2
EOF

For Flow Task ID (fn-N.M)

First check if task has existing spec from planning:

$FLOWCTL cat <id>

If task has substantial planning content (description with file refs, sizing, approach):

• •Do NOT overwrite — planning detail would be lost
• •Only ADD new acceptance criteria discovered in interview:
  bash

  # Read existing acceptance, append new criteria
  $FLOWCTL task set-acceptance <id> --file /tmp/acc.md --json
  

• •Or suggest interviewing the epic instead: /flow-next:interview <epic-id>

If task is minimal (just title, empty or stub description):

• •Update task with interview findings
• •Focus on requirements, not implementation details

$FLOWCTL task set-spec <id> --description /tmp/desc.md --acceptance /tmp/acc.md --json

Description should capture:

• •What needs to be accomplished (not how)
• •Edge cases discovered in interview
• •Constraints and requirements

Do NOT add: file/line refs, sizing, implementation approach — that's plan's job.

For File Path

Rewrite the file with refined spec:

• •Preserve any existing structure/format
• •Add sections for areas covered in interview
• •Include edge cases, acceptance criteria
• •Keep it requirements-focused (what, not how)

This is typically a pre-epic doc. After interview, suggest /flow-next:plan <file> to create epic + tasks.

Completion

Show summary:

• •Number of questions asked
• •Key decisions captured
• •What was written (Flow ID updated / file rewritten)

Suggest next step based on input type:

• •New idea / epic without tasks → /flow-next:plan fn-N
• •Epic with tasks → /flow-next:work fn-N (or more interview on specific tasks)
• •Task → /flow-next:work fn-N.M
• •File → /flow-next:plan <file>

Notes

• •This process should feel thorough - user should feel they've thought through everything
• •Quality over speed - don't rush to finish
