Engineering Super Intelligence Team — SKILL entry

Your software-engineering brain trust and decision-making partner. 70 named native personas across 11 cells — drawn from the people who built the cloud, the databases, the languages, the runtimes, the web platform, the security and reliability disciplines, the DevOps movement, and the AI-coding frontier — plus 9 personas cross-listed from the AI Super Intelligence Team. Reusable across any CoCo-routed prompt, invoked by the /SI-Eng-* slash commands. The team's primary purpose is to help take engineering decisions, not just review work after the fact.

Status: Roster build complete (2026-05-30).

- Roster: 70 native personas across 11 cells, locked after a /ultra-think pass on the draft 65 (added Lamport, Lattner, Torvalds, Liskov, Perlman; reclassified Ghemawat as archetype; split the former devops-platform-ai-coding mega-cell into devops-platform + ai-assisted-coding).

- Cross-listed: 9 ML-systems / AI-coding voices carry teams: [ai-super-intelligence, engineering-super-intelligence] — single file, dual membership, no duplication.

- Commands: 25 /SI-Eng-* slash commands installed at ~/.claude/commands/, generated from the shared template by superintelligence/ai/scripts/build_commands.py --team Eng.

This file is the user-facing entry point. The machine source of truth is `registry.json`, regenerated from persona frontmatter by python3 superintelligence/engineering/scripts/build_registry.py.

What this team is for

When a CoCo prompt is a high-stakes engineering decision — architecture, build-vs-buy, tech-stack choice, reliability or security tradeoff, cost call — the Engineering Super Intelligence Team plays the role of named external voices with documented, citable stances. Instead of "the panel said," every claim is attributed to a specific engineer. This lets convene synthesis:

• Surface real disagreement (DHH vs Fowler/Newman on microservices; Cantrill vs Vogels/Burns on cloud-vs-own-hardware; Harris vs Abramov on virtual-DOM-vs-compiler; Stroustrup vs Hoare on memory safety).
• Anchor stances to citable evidence (every public_stance in every persona carries an evidence_url).
• Stay honest about who drove which decision (lead-driver vs validator vs specialist vs swing).

The roster leans toward strong, opinionated, publicly-documented engineers — which makes it powerful for decide / tradeoff / stress-test / roast, and carries a known simplicity-maximalist / anti-hype tilt (Hickey, Carmack, DHH, Cantrill) that the architecture-and-process voices (Fowler, Hohpe, Newman, Kim, Forsgren) counterweight.

Slash commands (25 — installed)

25 /SI-Eng-* command files live at ~/.claude/commands/, generated from the shared template by python3 superintelligence/ai/scripts/build_commands.py --team Eng. Architecture is orchestrator-first: every action verb invokes /SI-Eng-Orchestrate to pick a custom 16–32 persona team and gate on user approval before executing.

Dispatcher + Orchestrator

• /SI-Eng — no args → roster + cell heatmap; with a subcommand, routes; with free text, defaults to :meeting.
• /SI-Eng-Orchestrate "<prompt>" — scores all 70 personas (domain match 40% + cell coverage 30% + productive-conflict pairing 30%), picks 16–32, approval gate via AskUserQuestion, hard 16–32 band, re-picks every invocation.

Identity surface — explicit overrides (skip the orchestrator)

• /SI-Eng-Ask <slug> "<question>" — one persona in voice.
• /SI-Eng-Huddle <cell-slug> "<topic>" — whole cell synthesizes.
• /SI-Eng-Meeting "<prompt>" — full convene with mandatory attribution.
• /SI-Eng-Read <slug> — print persona file inline.

Roster management

• /SI-Eng-Recruit <domain> "<why>" — propose new persona candidates for an under-covered domain.

Action surface (15, orchestrator-first)

Maintenance

• /SI-Eng-Refresh · /SI-Eng-Verify · /SI-Eng-VoiceCheck

Global flags (every command)

• --no-orchestrate — skip orchestrator; use all 70 personas.
• --cells <comma-list> — manually scope to cells.
• --personas <comma-list> — manually scope to slugs.
