Special case

Product Studio

I work alone, on large requests and short deadlines.

The product team I built with AI: twelve specialist agents in Claude Code. My bet: structured AI can extend what one person working alone delivers, without replacing human judgment. The system stops when the decision is mine and only counts a delivery as done with proof.

See the deliveries
  • 24days

    for a full product, from discovery to publication: Nexo Quality, a concept project.

  • 4days

    from request to presenting a client’s new website as a navigable prototype.

  • 12agents

    specialists, from research to audit. Ten have already worked on real projects.

  • 83days, 10 versions

    to build the system through version 1.0, counted in calendar time, not hours of work.

Role

Product Designer. Design and build.

Use

My own. Not publicly available.

Built on

Claude Code, by Anthropic.

Version

v1.0, October 2026

Limits: time saved has not been measured, and two of the twelve roles have not worked on real projects yet.

Why it exists

The problem

Design, development and QA all land on me. AI helps, but without control it fails in expensive ways.

In testing, it spent past the ceiling, skipped mandatory steps and called work done without proof.

System principle

Existence is not evidence. Completion requires proof.

The bet

Sizing the process to each request and demanding proof for every delivery can help someone working alone meet short deadlines.

In real use

Three scales: a full product, a client site and the requests of this portfolio. The first two ran on versions before 1.0.

Deliveries

  3. Day to day

    This portfolio

    September 29 to October 5, 2026 · 6 days

    Fourteen requests with a record: cases, color, background, navigation, loading screen and this page.

    • In 4, I rejected or sent back what the system delivered
    • In 4, QA or the independent critique found defects before publishing

Record of one request

The "Cases" item on this site, from request to publishing

A small request from October 4, 2026 shows the whole process: the Cases item in this site’s navigation. Pick a step to see its real record.

  1. Step 01 of 10

    WhoMe

    I asked whether a "Cases" item in the navigation was worth it, with a panel of my cases, and pointed to a reference site.

  2. Step 02 of 10

    WhoExecutive Orchestrator

    A medium task on an existing product. It chose the Lean path, planned four specialists and set a mandatory visual stop: the reference was shaping the direction.

    On record

    • Path: Lean
    • Specialists planned: 4
    • Specialist ceiling: 220,000 tokens
  3. Step 03 of 10

    WhoSystem, with an automated browser

    Before offering an opinion, it opened the reference site and measured the panel, which opens on hover and becomes a text list on mobile.

    On record

    • Panel: 682 × 368 px
    • List: 322 px, rows of 58 px
    • Preview: 360 px
  4. Step 04 of 10

    WhoUX Architecture Lead

    Recommended with adjustments and recorded the argument against: with three cases the gain is small, because the Home already shows them.

    On record

    • Opinion: recommended with adjustments
    • On a phone: text list, no image
  5. Step 05 of 10

    WhoUI Lead and Interaction Lead, in parallel

    One specified the panel, the other the behavior with mouse, keyboard, touch and reduced motion. The two diverged on an 8 px gap, resolved without changing the look.

    On record

    • Panel: 760 × 436 px
    • A 340 px list and a 420 px preview
    • 26 acceptance criteria
  6. Step 06 of 10Waiting for a decision

    WhoMe

    The system stopped before building and asked two questions: who builds it, and what a click on the item does. I answered "use the method you think is best" and "it only opens the panel".

  7. Step 07 of 10

    WhoSystem, no specialist

    It built the panel and measured the result in the browser, at three widths. It tested mouse, keyboard and touch and checked contrast with a script.

    On record

    • Panel measured: 760 × 436 px
    • 11 color pairs, the lowest at 6.28:1
    • No text under 16 px
  8. Step 08 of 10Waiting for a decision

    WhoMe

    I approved it with changes. The subtitles did not stand out and the titles were too heavy. The system rewrote the three subtitles and changed the title font.

  9. Step 09 of 10

    WhoQA and Release Lead

    It redid the critical tests on its own. Approved with conditions, no serious defect, and declared what it did not test: touch on a real device, screen reader and other browsers. Cost passed the alert line and was recorded.

    On record

    • Verdict: passed with conditions
    • 1 minor finding, no fix needed
    • Cost: 190,021 of 220,000 tokens
  10. Step 10 of 10Waiting for a decision

    WhoMe

    Nothing goes live without an explicit request. I asked for one last change to the menu order and wrote "you can publish". It was published and checked in production the same day.

    On record

    • 10 pages checked in production
    • Total cost: 278,113 tokens, with classification

On the yellow steps, the system stopped and waited for my decision.

Cumulative cost of specialists

190,021 of 220,000 tokens

Tokens are the unit of AI usage. The ceiling is set before the work starts.

From request to delivery, at the right size

I write the request as I would for a team. An orchestrator agent always follows the same six steps and calls in only the specialists the request needs. The decisions listed at the top are mine; the system recognizes them and asks.

  1. Understands the request

    Checks sources and marks what it does not know.

  2. Picks the path

    Direct, Lean or Full, by size.

  3. Calls in specialists

    Only the ones needed, with minimal context.

  4. Measures cost

    Checks the budget before every call.

  5. Stops and asks

    Scope, visual direction, budget and publishing wait for my answer.

  6. Proves and delivers

    QA verifies with evidence; only then does the delivery count.

Four rules that hold the system together

  1. Human decision

    Rule

    The system recognizes the decision point, stops and presents the options. It never approves on its own.

    Evidence

    In the final test, 2 pauses for budget waited for real answers before work continued.

  2. Selective context

    Rule

    Each specialist gets only what the decision requires and records the reason if it reads more. It is not reliable yet: in tests, specialists read more than needed.

    Evidence

    Average cost per call had risen 79% when each specialist read the full instructions.

  3. Cost Guard

    Rule

    Before each call, it checks the budget; afterward, it records the real cost. At the ceiling, it stops and waits for a human decision.

    Evidence

    One cost test reached 117,244 tokens, 27,244 above its 90,000 ceiling.

  4. Completion by evidence

    Rule

    Done requires three things together: the output, the verification and the evidence left behind.

    Evidence

    The auditor rejected the release candidate 3 times; the last one only for lack of a real test.

My role, decisions and limits

My role

I designed and built the system for my own work. In use, scope, direction and publishing are my decisions.

Decisions I made

  • Instead of closing the release with the final test pending, I required a real test in a fresh session. Criterion: done requires proof. Cost: the release waited for that test and for two budget increases. Consequence: the auditor rejected the candidate 3 times, the last one only for lack of that test.
  • I rejected the visual direction of one test: the process had passed, but the visuals had not. Criterion: what you see, not what the process completed. Cost: about 550k tokens already spent before the first honest visual critique. Consequence: the independent visual critique became mandatory.
  • I authorized, one by one, the two budget increases of the final test, instead of letting the system go past the ceiling. Criterion: the ceiling is the rule and only I can release an exception. Cost: less autonomy. Consequence: both pauses waited for my answer.

Known limits

  • The full product and the client site ran on versions before 1.0, without its cost record. The 83 days are calendar time, not hours.
  • In real use, the Lean path went over its ceiling more than once and needed my release. The final test was not blind, and formal validation is small.

The system up close

Requests, build history, routing, agents, toolkit and next steps. Open only what you want to check.

What was asked and what happened

Fourteen requests, each with what I asked and what happened. Ten are live.

Full square: it is live. Empty: it was not published.

  1. Sep 29

    Review the copy of the cases

    Published the same day. (live)

  2. Sep 29

    Color: yellow and color photos

    The independent critique flagged 2 problems that did not exist. They were checked and dismissed. (live)

  3. Sep 30

    3 Lírios case

    The independent critique scored it 27 of 40 and flagged 3 important problems. After the revision, 30.5 of 40. (live)

  4. Sep 30

    Raise the level of the other cases

    QA passed it and flagged 1 minor defect, fixed before publishing. (live)

  5. Sep 30

    Nexo Quality: explanation on cards and sidebar

    QA found 1 layout defect. It was fixed, and only then published in Portuguese and English. (live)

  6. Oct 2

    Background with gradient and animated lines

    I approved the direction for the case pages. (live)

  7. Oct 2

    More artistic lines in the background

    I rejected both variants. Neither was published. (not published)

  8. Oct 2

    Direct interaction in the case frames

    QA rejected the first delivery: on a phone, a map trapped the page scroll. Fixed and rechecked. (live)

  9. Oct 3

    Loading screen with the logo

    I rejected two versions before the one that is live. (live)

  10. Oct 4

    "Cases" item in the navigation

    I approved it with changes. It is the record shown above. (live)

  11. Oct 5

    This page, first version

    I asked for a full review: I was not sure it explained the whole system. (not published)

  12. Oct 5

    This page, second version

    I asked for it to be completed: the technologies, the libraries and everything the system has were missing. (not published)

  13. Oct 5

    This page, third version

    I asked whether it would make a recruiter’s eyes light up. The assessment was not yet, with four problems named, and I approved the changes. (not published)

  14. Oct 5

    This page, current version

    It is what you are reading. (live)

83 days, 10 versions

From the first file, on July 15, 2026, to version 1.0, on October 5. Each version records the failure behind it.

  1. Jul 15 to 24

    Architecture and roles

    Twelve roles with written contracts, activated, and a single command that receives the requests.

  2. Aug 3 to 10

    Visual quality and cost

    Versions 0.9.2 to 0.9.4: cost control and the rule of seeing pixels before deciding.

  3. Aug 26

    Proof and proportion

    Versions 0.9.5 and 0.9.8: completion by evidence, selective context and the three paths.

  4. Oct 5

    Version 1.0

    The candidate was rejected by the auditor. Fixed, tested and frozen.

Two failures that changed the architecture

Each row is a measured failure and the change it caused.

  1. The process passed, the visuals failed

    ~550k

    tokens spent before the first honest visual critique

    Change

    See before deciding. No visual direction moves forward without real pixels of the concept and a human decision.

  2. The release candidate was rejected by the auditor

    5.46x the ceiling

    1,201,867 tokens against a ceiling of 220k

    10 specialist calls ran after a pause that was mandatory.

    Change

    A real Cost Guard. Whoever calls the specialists measures real cost at every step and stops at the ceiling.

Three paths, one for each size of request

Every request is classified before it runs. Lean is the default; Full only comes in when risk or complexity call for it.

Every request is classified and takes one of three paths. Direct: a contained task, 0 specialists, a simple check, no independent audit and no state summary; it ends in a delivery with evidence. Lean, the default: usually 1 to 3 specialists, proportional QA, a light audit if risk calls for it and a state summary if the work spans sessions. Full: only when risk or complexity call for it; in the test, 6 of 12 roles, with formal QA, audit according to risk and a state summary required across sessions. Lean and Full end in a delivery with evidence or in a budget pause, waiting for a human decision.

Request

Classification

  • Where the work happens: design, code or both
  • Expected level of finish
  • What is fixed, negotiable or open

Direct

A contained task, checkable on the spot, with no specialist.

  • Specialists: 0
  • QA: simple check
  • Independent audit: no
  • State summary: no

Lean

The default: a few specialists and limited risk.

  • Specialists: 1 to 3, usually
  • QA: proportional
  • Independent audit: light, if risk calls for it
  • State summary: if it spans sessions

Full

Only when risk or complexity call for broad coordination.

  • Specialists: 6 of 12 in the test
  • QA: formal
  • Independent audit: according to risk
  • State summary: required across sessions

Delivery with evidence

completion by evidence

or

Budget pause

waiting for a human decision

Cost Guard. Only on paths that call in specialists.

Full square: always. Half full: under a condition. Empty: no. Line weight shows how broad the process is, not its cost.

Twelve specialist agents, by discipline

Each role is a Claude Code subagent with a written contract: what it delivers, what it does not decide and when it must stop. Only the ones the request needs are called in.

    Use real costs so it stops pausing before it builds.

  2. Measure the Full path

    The only formal data point predates the v1.0 rules.
