Engineering Super Intelligence Team — SKILL entry
Rijul's 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-thinkpass on the draft 65 (added Lamport, Lattner, Torvalds, Liskov, Perlman; reclassified Ghemawat as archetype; split the formerdevops-platform-ai-codingmega-cell intodevops-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 bysuperintelligence/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_stancein every persona carries anevidence_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.

Conventions
- Schema source of truth:
superintelligence/templates/persona.md. Edit there first. - Registry regeneration:
python3 superintelligence/engineering/scripts/build_registry.pyafter any persona edit; thenbuild_cells.pyfor the cell docs. - Attribution at every line. No "the team said" — name a persona or a cell.
- Citation is mandatory. Every
public_stancehas anevidence_url. No uncited claims. - Caveman mode does NOT apply to persona files, cell files, or this SKILL.md. Documentation is always full English prose per the project rule.
- Cross-team personas are single-file with a
teams: [...]array and ahome_teampointer. Never duplicate a persona file across teams.
Build provenance
- Built 2026-05-30 by Rijul Kalra during a /coco session, immediately after the AI Super Intelligence Team.
- Roster scrutinized via
/ultra-thinkbefore build: 5 canon adds, Ghemawat → archetype, mega-cell split, two all-male cells de-skewed (Liskov → craft, Perlman → cloud-architecture). - 70 native personas built by parallel research sub-agents across staged waves (cloud, reliability, data, security, finops, languages, systems, web, ai-coding, craft, devops). A mid-build rate-limit reset 18 craft/devops/systems/web personas; they were re-run cleanly.
- Quality bar matched the AI team's Karpathy reference (≥8 cited URLs, ≥3 recent signals, every public_stance cited, full 6-section narrative). Many agents corrected stale title/affiliation assumptions against verified 2026 facts (e.g., Hamilton SVP not VP; Brooker promoted to VP; Stamos now CSO at Corridor; Kleppmann back at Cambridge; Liz Fong-Jones now Technical Fellow; Forsgren single-employer Microsoft; Nat Friedman confirmed at Meta Superintelligence Labs).
- All persona files written in full English prose. Caveman mode active in chat throughout.
