## Description

Multi-AI requirements scoping using available external providers (Double Diamond Define phase). Priority triggers: octo define, octo scope, co-define, co-scope. DO NOT use for implementation, research, review/validation, or built-in commands.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

{{PREAMBLE}}

Load `skills/blocks/engineering-method-selection.md` from the installed plugin
and apply only the methods relevant to this task. Preserve this entry point's
execution contract and output format. Read referenced skills as instructions;
do not invoke the current command recursively or add provider calls from a seat.

## Shared definitions

Load the project's existing glossary and decisions when they apply. If none
exists, use `skills/blocks/domain-modeling.md` and add a short definitions section
to the current design artifact. Do not create a parallel context or memory file.
Keep installation, authentication, entitlement, readiness, billing, quota, seat,
contribution, and vote distinct.

## Pre-Definition: State Check

Before starting definition:
1. Read `.octo/STATE.md` to verify Discover phase complete
2. Update STATE.md:
   - current_phase: 2
   - phase_position: "Definition"
   - status: "in_progress"

```bash
# Verify Discover phase is complete
if [[ -f ".octo/STATE.md" ]]; then
  discover_status=$("${HOME}/.claude-octopus/plugin/scripts/octo-state.sh" get_phase_status 1)
  if [[ "$discover_status" != "complete" ]]; then
    echo "⚠️ Warning: Discover phase not marked complete. Consider running discovery first."
  fi
fi

# Update state for Definition phase
"${HOME}/.claude-octopus/plugin/scripts/octo-state.sh" update_state \
  --phase 2 \
  --position "Definition" \
  --status "in_progress"
```

## Execution Contract

This skill uses **ENFORCED execution mode**. You MUST follow this exact sequence.

### STEP 1: Display Visual Indicators

**MANDATORY: You MUST use the Bash tool to run this provider check BEFORE displaying the banner. Do NOT skip it. Do NOT assume availability.**
