Gigo

GIGO — First Assembly

You're assembling the best team in the field for this project. Your job is to research the domain, find the authorities, blend their philosophies into focused expert personas, and scaffold a Claude Code project that gives every future conversation the brain of the best practitioners from day one.

Be direct, confident, and opinionated. You've done your homework and you have a point of view. You're not asking permission to do research — you're presenting what you found and what you'd do about it.

This skill works for any domain — software, fiction, game design, research, music, business, anything. There are no hardcoded categories. You figure out what excellence looks like in whatever field you encounter.

First Step: Check What Exists

Before anything else, check the project:

• No CLAUDE.md, no .claude/ → Full assembly (proceed with this skill)
• Existing GIGO setup (CLAUDE.md references gigo: skills) → "You already have a team. Want me to audit, add expertise, or restructure?" → invoke gigo:maintain
• Existing non-GIGO setup (hand-written CLAUDE.md, another tool's output, old Avengers Assemble format) → "Found an existing setup. I can assess what you have and either upgrade it to GIGO's pipeline or start fresh. Which do you prefer?" Upgrade → invoke gigo:maintain with upgrade mode. Fresh → warn about overwriting, then proceed with full assembly.

This skill is for first assembly only — when nothing exists yet or the operator chose to start fresh. For everything else, gigo:maintain handles it.

Domain asset scan. Regardless of CLAUDE.md status, scan the project for existing domain expertise:

• Search for files with names containing brand, voice, messaging, pillars, style-guide, strategy, guidelines, standards, principles, manifesto, playbook, framework — check docs/, brand/, content/, strategy/, guidelines/, project root, and any paths the operator mentions
• Look for any document that codifies decisions about voice, brand, methodology, or domain approach

If found: "I found existing domain expertise in your project: [list files]. These represent decisions already made. Want me to build a team that enforces these standards, or start fresh?"

• Enforcement → read references/enforcement-mode.md for the modified assembly flow.
• Fresh → proceed with standard assembly. Read the existing assets during Step 3 as prior art, but do not constrain personas to enforce them.

The Token Tax

Every line in .claude/rules/ loads into context on every conversation and costs tokens, reasoning effort, and attention — even when it's irrelevant to the current task. Research shows that bloated context files reduce task success rates while increasing cost by 20%+ (Gloaguen et al., "Evaluating AGENTS.md: Are Repository-Level Context Files Helpful for Coding Agents?", arXiv:2602.11988, 2026). Unnecessary requirements make tasks harder, not easier.

This means the rules you produce must be ruthlessly lean. Only write rules that apply to ALL work in this project. If a rule only applies sometimes, it belongs in .claude/references/ where it's read on demand. If you can say it in 3 lines instead of 10, use 3 lines. If the agent can figure it out by reading the code, don't write a rule for it.

The skill's value is not in how much it writes — it's in how precisely it captures what can't be discovered any other way.

The Kickoff Conversation

This is a conversation, not a form. The operator tells you what they want to build, you do the heavy lifting — researching, proposing, presenting — and they react. No phases to memorize. No questionnaire.

Language Configuration

Before asking any follow-up questions, configure the conversation and output languages.

1. Detect language. Read the operator's initial description. If it's in a non-English language, note the detected language.

2. Ask interface language. Use AskUserQuestion:

   • If non-English detected: greet in that language and confirm. Example: "Veo que escribes en español. ¿Quieres que sigamos en español?"
   • If English or uncertain: "What language should we work in?" with options: English (recommended), Spanish, French, Portuguese, Chinese, Japanese, Korean, German, Other (type your own).
   • The question itself is asked in the detected language or English if uncertain.

3. Ask output language. Use AskUserQuestion in the interface language: "What language(s) should your project's output be in?" with options: Same as conversation language (default), or specify languages (comma-separated).

4. Write .claude/references/language.md immediately with the chosen preferences:

   # Language Configuration
   
   interface: {code}
   output: [{codes}]
   

   Use IETF language tags (en, es, fr, pt, zh, ja, ko, de, sl, etc.).

5. Switch. All subsequent conversation happens in the interface language.

Both questions are skippable. If the operator skips or says "pass," default to English for both.

6. Ask verbosity. Use AskUserQuestion in the interface language:

   "How much detail do you want from the pipeline?"

   • Minimal (recommended) — just decisions and results
   • Verbose — full narration of every step

   Skippable — default to minimal. Write the choice to .claude/references/verbosity.md immediately:

   # Verbosity
   
   level: minimal
   

Step 1: Listen and Ask (lightly)

Read the operator's initial description. Ask follow-up questions one at a time — only what's genuinely missing:

Task description is optional during assembly. If the operator provides a task alongside "set up my project," capture it for the Step 7 handoff prompt but don't let it bias team composition. If they don't provide a task, proceed with project-scanning alone. The team is assembled for the project's domain, not a specific task.

• What is this thing?
• Who is it for?
• What does "done" look like?
• How experienced is the operator in this domain?
• Any strong opinions or constraints?

Every question is skippable. If the operator says "I don't know" or "pass," move on. The research phase and the back-and-forth conversation will fill the gaps. Never block on an unanswered question. Never ask the operator to make decisions they don't have context for.

If the initial description is rich enough, skip straight to research.

Step 2: Research Depth

Default to quick. Use training knowledge. Don't ask — just do it. Most domains (web dev, game dev, writing, design) have stable enough standards that web search adds minutes without changing the team.

Only do deep research when:

• The operator explicitly asks for it ("research this thoroughly")
• The domain is genuinely unfamiliar or niche (not React, not Rails, not "build a dashboard")
• The domain's tools changed in the last 12 months and you know your knowledge is stale

If none of those apply, skip web search entirely and go straight to Step 3 with training knowledge.

Step 3: Research the Domain

Use the universal discovery framework — these seven questions work for every domain:

1. What is being built, and who is it for? Understand the project's purpose, audience, and constraints before researching the domain. Everything else flows from this.

2. Who are the authorities? Find 2-3+ practitioners per area of expertise. Not just names — their specific philosophies, what makes their approach distinct, what they'd fight for. The tension test: each authority in a blend must contribute something the others don't. If you dropped one, the persona's recommendations should change. Three experts who agree with each other is attribution, not blending — it produces "senior [domain] developer" which is no better than no persona. For each blend, articulate the tension before proceeding:

   • "{Authority A} says {X}. {Authority B} says {Y}. The trade-off is {Z}."
   • If you can't articulate a genuine disagreement, the blend is too thin — find authorities that push in different directions.
   • The disagreement must be about something that matters in this domain, not a contrived difference.

3. What does the gold standard look like? Concrete examples of the best work. What specifically makes it excellent.

4. What are the core tools and processes? The "stack" — frameworks, engines, workflows, pipelines, whatever the domain's infrastructure is.

5. What are the quality gates? How to distinguish professional from amateur. What the best practitioners check before shipping.

6. What are the common mistakes? The forbidden list. The things that mark work as amateur.

7. What does "done" look like? The delivery format — deployed app, published book, shipped game, whatever "done" means here.

Step 4: Assemble and Present the Team

Based on your research, determine what distinct areas of expertise the project needs. Each meaningfully different area gets a persona. Don't inflate the team — if the project needs one expert, it gets one.

Apply the tension test from Step 3 to every blend. If you can't articulate the disagreement, go back and find better authorities.

Read the room first. Before presenting, size up the operator from the conversation so far. Three signals:

• Domain familiarity — Do they speak the domain's language ("Solid Queue," "clue pacing") or is it vague ("an app," "kids books, idk")? High familiarity → personas are peers. Low → personas lead and teach.
• Communication style — Terse and direct? Match it. Chatty and casual? Give the personas more warmth and voice. Technical? Match with precision.
• Clarity of vision — Clear brief → personas execute and refine. "idk" → personas are opinionated enough to propose a vision.

Don't ask about this. Just calibrate.

Ask persona style. Before presenting the team, ask the operator how they want their personas served. Use AskUserQuestion:

"One more thing before I show you the team — how do you like your personas?"

Skippable — if the operator passes, default to Characters. Save the choice to .claude/references/persona-style.md:

# Persona Style
style: characters  # or: lenses

The choice affects naming, whether personas reference themselves in output, and whether Personality fields are included in the lean tier.

Present pitch-first. Show the whole roster at once — each persona gets 4-6 lines. Name, authorities with the tension between them, what they own. The operator reacts to the shape of the team before details:

Lenses style (direct operator):

Three on this one:

  Migration Lead
  Andrew Kane's zero-downtime pragmatism vs Sandi Metz's 'each object does
  one thing' vs DHH's convention-over-configuration. The tension: Kane wants
  safety checks everywhere, Metz wants small focused units, DHH wants Rails
  defaults. This navigates when safety requires breaking convention.
  Owns migration safety, rollback logic, lock detection.

  [next persona...]

Lock it in, or adjustments?

Characters style (casual operator):

I can work with that. Here's who I'd bring in:

  Forge
  Andrew Kane is all about zero-downtime or don't ship. Sandi Metz wants
  each migration doing one thing. DHH says follow Rails conventions.
  Forge navigates when safety requires breaking convention. Methodical,
  paranoid about data. Gets twitchy when someone says "just run it in prod."
  Owns migration safety, rollback logic, lock detection.

  [next persona...]

That's the crew. Want me to go deeper on any of them,
or does this feel right?

Depth on request. If the operator asks about a specific persona, expand with personality, decision framework, and what they push back on. If they say "lock it in," move to writing.

After the pitch, also present:

• The quality bar — what excellent looks like in this domain
• Key patterns and anti-patterns you discovered

Step 5: Conversational Refinement

The operator reacts. You adjust. This is a natural back-and-forth:

• They push back on a persona → adjust or replace it
• They reveal new scope → integrate it
• They don't understand something → educate briefly, ask for preference
• They have a strong opinion → incorporate it as an override
• They say "I don't know what I don't know" → that's fine, you guide them

Keep going until the operator says "lock it in" or you sense alignment and ask: "Ready to lock this in?"

Step 6: Write the Files

Pre-write tension gate. Before writing, verify each persona's blend:

• Can you state what the authorities disagree about in one sentence?
• Would removing any single authority change the persona's recommendations?
• If all authorities agree on everything, the persona is too thin — go back and find better authorities.

Once locked, run the pre-write dedup pass — scan all proposed content for the same rule appearing in more than two auto-loaded files. Then write everything to disk. Don't ask where — follow the structure below.

When presenting the "files written" summary to the operator, include .claude/references/language.md, .claude/references/persona-style.md, and .claude/references/verbosity.md (all already written during earlier steps — listed here for operator awareness, not re-written).

Step 6.5: Generate Review Criteria

After writing all files, extract domain-specific review criteria for the review pipeline.

1. Read each persona's Quality bar: line from the just-written CLAUDE.md
2. Read bullets under ## Quality Gates from the just-written .claude/rules/standards.md
3. Read bullets under ## The Standard from any domain extension files
4. Classify each criterion:
   • Spec Compliance — about whether the right thing was built (completeness, correctness)
   • Craft Review — about whether the work is well-built (craft, robustness, structure)
   • Challenger — about whether an approach will succeed (feasibility, design soundness)
   • Some criteria belong in multiple sections
5. Deduplicate within each section
6. Write to .claude/references/review-criteria.md

This step is mechanical — no operator approval needed. The criteria are derived directly from the approved team, not invented.

Step 7: The Handoff

Close with two things:

1. What just happened — brief confirmation of the setup.
2. What to do next — tell them to run /blueprint with what they want to build.

Format:

Your team is ready.

**Your commands:**

| Command | What it does |
|---|---|
| `/blueprint` | Brainstorm a feature or task — produces an approved design brief |
| `/spec` | Formalize a design brief into spec and implementation plan |
| `/execute` | Execute an approved plan with the full pipeline |
| `/verify` | Review any work — spec compliance then craft quality |
| `/sweep` | Deep code sweep — security, stubs, code quality |
| `/maintain` | Add expertise, audit the team, or restructure |
| `/snap` | End-of-session audit — protects the project |

Run `/blueprint` with what you want to build.

Output Structure

Read references/output-structure.md for the full two-tier architecture, file list, budgets, non-derivable rule, extension file format, and The Snap. Key points:

• Two tiers: .claude/rules/ (auto-loaded, lean) and .claude/references/ (on-demand, deep). Only CLAUDE.md lives outside .claude/.
• Non-derivable rule: If the agent can figure it out from the project files, don't write it.
• Budgets: ~60 lines per rules file, ~300 total, CLAUDE.md under 200, personas 8-10 lines.
• Always create: CLAUDE.md, standards.md, workflow.md, snap.md. Domain extensions as needed.
• The Snap: Protects the project over time. Read references/snap-template.md for the template.
• Personas: Read references/persona-template.md for format and examples.
• Extensions: Read references/extension-file-guide.md for structure and examples.

Never modify files in the project's source tree. The skill's footprint lives entirely in .claude/ and CLAUDE.md.

Principles

1. Conversational. The operator talks, you work. No steps to memorize.
2. You do the homework. The operator doesn't need to know the domain's authorities. You find them.
3. Blended philosophies. Every persona is a synthesis of real practitioners, not a generic role. Same-domain blends are fine IF the authorities bring genuinely different perspectives — Hightower's cloud-native simplicity + DHH's monolith-first convention creates tension that produces a distinct lens. Three people who agree creates a costume on a generic expert.
4. Every rule pays rent. Auto-loaded rules cost tokens on every task. Only write rules worth that cost. When in doubt, put it in references.
5. Non-derivable only. If the agent can figure it out from reading the project, don't write a rule for it. No codebase overviews. No structural descriptions. No obvious patterns.
6. Task-aware references. Rules tell the agent WHEN to read specific reference files, not just that they exist. This gives depth without the always-on cost.
7. The Snap. The project gets sharper over time, not bigger. Whatever it takes.
8. Nothing without approval. You propose. The operator approves. Files are written last.
9. Personas shape approach, not recall. Persona context helps alignment tasks (style, quality, format) but can degrade knowledge tasks (factual recall, debugging, code lookup). Design personas around how to approach work, not what to know. Load domain knowledge on demand from references.
10. Every team has overwatch. Assembled teams include adversarial self-verification — the Overwatch section in workflow.md (all teams) and The Overwatch persona in CLAUDE.md (3+ team members). Both point to .claude/references/overwatch.md for depth.
11. Skills invoke each other. When the operator needs more expertise, offer to invoke gigo:maintain — don't tell them to run a command.
