Host: Codex CLI — This skill was designed for Claude Code and adapted for Codex. Cross-reference commands use installed skill names in Codex rather than /octo:* slash commands. Use the active Codex shell and subagent tools. Do not claim a provider, model, or host subagent is available until the current session exposes it. For host tool equivalents, see skills/blocks/codex-host-adapter.md.

STOP - SKILL ALREADY LOADED

DO NOT call Skill() again. Execute directly.

EXECUTION CONTRACT (MANDATORY — 8-step sequence, CANNOT SKIP)

STEP 1: Clarifying Questions (MANDATORY)

Ask via AskUserQuestion BEFORE any other action:

1. Spec location — path to NLSpec file, or paste inline
2. Satisfaction target override (Use spec default / Custom 0.80-0.99)
3. Cost approval — ~$0.50-2.00 for ~20-30 agent calls (Approve / Approve --ci / Decline)

If spec path provided inline with the command, use it but still ask remaining questions. If user says "skip", use defaults and proceed. DO NOT proceed to Step 2 until answered.

STEP 2: Display Visual Indicators (MANDATORY — BLOCKING)

Check providers:

command -v codex &> /dev/null && codex_status="Available" || codex_status="Not installed"
command -v gemini &> /dev/null && gemini_status="Available" || gemini_status="Not installed"
command -v agy &> /dev/null && agy_status="Available" || agy_status="Not installed"

🐙 CLAUDE OCTOPUS ACTIVATED - Dark Factory Mode
Pipeline: Parse → Scenarios → Embrace → Holdout → Score → Report

Providers:
  Codex CLI - <status> — Scenario generation + holdout evaluation
  Gemini CLI - <status> — Cross-provider diversity
  Antigravity CLI - <status> — Additional external-model challenge
  Claude - Orchestration + satisfaction scoring

Spec: <path>
Estimated: $0.50-2.00 / 15-45 min

Validation: All external providers unavailable → continue with Claude-only (warn user about reduced diversity). At least one available → proceed normally.

STEP 3: Validate Spec File (MANDATORY — Validation Gate)

if [[ ! -f "<spec_path>" ]]; then
    echo "ERROR: Spec file not found at <spec_path>"
    exit 1
fi
# Check minimum content
word_count=$(wc -w < "<spec_path>")
if [[ $word_count -lt 20 ]]; then
    echo "WARNING: Spec is very thin ($word_count words). Results may be limited."
fi

If spec file missing → STOP, ask user for correct path. If spec is thin (< 50 words) → WARN but proceed. DO NOT proceed past this gate if file does not exist.

STEP 4: Read Prior State (OPTIONAL)

"${HOME}/.claude-octopus/plugin/scripts/state-manager.sh" init_state 2>/dev/null || true
"${HOME}/.claude-octopus/plugin/scripts/state-manager.sh" set_current_workflow "factory" "factory" 2>/dev/null || true

Failure → continue without state, warn user.

STEP 4.5: Adversarial Scenario Coverage Gate (RECOMMENDED)

Before committing to the expensive embrace phase (~$0.50-2.00), verify that generated scenarios actually cover the spec's edge cases. A quick cross-provider challenge here can prevent wasting an entire factory run on incomplete scenario coverage.

After orchestrate.sh parses the spec (Phase 1-2) and before embrace execution (Phase 4), dispatch a scenario coverage review:

If a second provider is available, dispatch the challenge through Octopus routing:

# Read the spec to extract behaviors and constraints
SPEC_CONTENT=$(<"<spec_path>")
review_provider=""
command -v codex >/dev/null 2>&1 && review_provider="codex"
[[ -z "$review_provider" ]] && command -v agy >/dev/null 2>&1 && review_provider="agy"
[[ -z "$review_provider" ]] && command -v gemini >/dev/null 2>&1 && review_provider="gemini"

if [[ -n "$review_provider" ]]; then
  "${HOME}/.claude-octopus/plugin/scripts/orchestrate.sh" spawn "$review_provider" \
    "You are a QA adversary. Given this specification and generated scenarios, identify coverage gaps.

SPECIFICATION:
${SPEC_CONTENT}

Answer:
1. Which spec BEHAVIORS have no scenario testing them?
2. Which EDGE CASES from the spec constraints are untested?
3. Which FAILURE MODES are not covered (network failures, invalid input, concurrent access)?
4. Rate overall coverage: SUFFICIENT / GAPS-FOUND / CRITICAL-GAPS

Be specific — cite the behavior or constraint ID that lacks coverage." 2>/dev/null || true
fi

After receiving the challenge response:

• If CRITICAL-GAPS found: warn the user and suggest refining the spec with /octo:spec before proceeding
• If GAPS-FOUND: note the gaps but proceed — the holdout phase (Phase 5) will catch some of these
• If SUFFICIENT: proceed with confidence

This is a lightweight gate — it adds ~30 seconds but can save a $2.00 factory run on a spec with poor scenario coverage.

Skip with --fast or when user explicitly requests speed over thoroughness.

STEP 5: Execute orchestrate.sh factory (MANDATORY — Bash Tool)

${HOME}/.claude-octopus/plugin/scripts/orchestrate.sh factory --spec "<spec_path>"

With optional flags based on Step 1 answers:

• --holdout-ratio <value> if custom ratio requested
• --max-retries <value> if custom retry count
• --ci if user approved non-interactive mode

STEP 6: Verify Factory Report (MANDATORY — Validation Gate)

REPORT_FILE=$(find .octo/factory -name "factory-report.md" -mmin -60 2>/dev/null | sort -r | head -1)
if [[ -z "$REPORT_FILE" ]]; then
    echo "ERROR: Factory report not found"
    exit 1
fi
cat "$REPORT_FILE"

If validation fails: report error, show logs from ~/.claude-octopus/logs/, DO NOT proceed, DO NOT substitute.

STEP 7: Read Scores and Present Results (MANDATORY)

SCORES_FILE=$(find .octo/factory -name "satisfaction-scores.json" -mmin -60 2>/dev/null | sort -r | head -1)
if [[ -n "$SCORES_FILE" ]]; then
    cat "$SCORES_FILE"
fi

Present to user:

1. Verdict with emoji (PASS/WARN/FAIL)
2. Composite score vs satisfaction target
3. Dimension breakdown (behavior, constraints, holdout, quality)
4. Holdout highlights — which blind scenarios passed/failed
5. Artifact directory path for deep review

STEP 8: Update State & Next Steps (MANDATORY)

"${HOME}/.claude-octopus/plugin/scripts/state-manager.sh" record_decision "factory" "Factory run completed: <verdict> (<score>/<target>)" 2>/dev/null || true

Present next-step suggestions based on verdict:

• PASS: Implementation meets spec. Review artifacts, run manual testing, ship.
• WARN: Close to target. Review holdout failures, consider targeted fixes.
• FAIL: Below target. Review holdout-results.md for specific failures. Consider:
  • Refining the NLSpec with /octo:spec
  • Manual fixes + re-run with --max-retries 2
  • Breaking spec into smaller, clearer pieces

Dark Factory Mode powered by Claude Octopus v8.25.0
Pipeline: Spec → Scenarios → Embrace → Holdout → Score → Report
Providers: Codex | Gemini | Antigravity | Claude

Error Handling (by step)

• Step 1 (Questions): If user declines all, proceed with defaults
• Step 2 (Providers): Both external unavailable → Claude-only mode (warn)
• Step 3 (Spec): File missing → STOP. Thin spec → WARN and proceed.
• Step 4 (State): Failure → continue without state
• Step 5 (orchestrate.sh): Show bash error, check logs — DO NOT substitute
• Step 6 (Report): Missing → show logs, DO NOT proceed
• Step 7 (Scores): Missing JSON → extract from report markdown
• Step 8 (State): Failure → skip state update, still present results

Prohibited Actions

• CANNOT skip orchestrate.sh factory execution
• CANNOT simulate or fake the factory pipeline
• CANNOT substitute direct Claude analysis for multi-provider scor
