I spent $1,000 on Claude Fable 5 (Mythos), it's incredible
A 14-minute first-impressions report on the best coding model available — and the 12-day window before it stops being free.
June 11thHow one developer chained a computer-use verification loop and an automated code-review loop to ship 75+ pull requests with an AI cloud agent, without reading most of the code.
A two-loop system that forces an AI agent to prove its fix works via recorded computer-use testing, then iterate against automated code review until a perfect score, is what let one developer ship over 75 pull requests in about a week without manually reviewing most of the code.
The video breaks down a two-loop workflow for shipping code with AI cloud agents. Loop 1: a ticket from Linear gets assigned to a cloud agent (Cursor Cloud or Devin), which writes code, then uses computer-use to actually operate the app and record video proof the fix works, retrying until the recorded desired state is achieved. Loop 2: once the agent opens a pull request, an automated review tool (Greptile) scores it out of 5; anything under a perfect score gets sent back to the agent to refine and resubmit until it passes, at which point a human does a final review. The core lesson: a loop only works if the success condition is unambiguous and machine-checkable — write clear expected/actual behavior into the ticket and let computer-use verify it, rather than trusting the agent's self-report.

States the headline number, gives a status update on Fable 5 access and weekly usage limits, promises a full breakdown of the loop.

Teases the loop diagram from a June 19 tweet, then introduces Linear as the system of record for feature requests and bug reports, with fields for steps to reproduce, expected behavior, and actual behavior.

Demos Framer's AI agent cloning two reference sites and a design system from a single prompt each.

Shows clicking assign on a Linear ticket to hand it to Cursor Cloud or Devin via MCP; the cloud agent picks it up and starts working independently.

Explains the first loop: agent builds, uses computer-use to test the app on a virtual desktop, records the result, evaluates against the ticket's desired state, and retries if not achieved.

A Google Sheets connector-permissions test (including a first attempt that correctly fails) and an agent-card onboarding flow, both verified by recorded computer-use.

Once loop 1 closes, the agent opens a PR with an attached demo video; Greptile scores it out of 5; under 5/5 triggers refine-and-resubmit via the grep loop skill until it passes.

Clarifies where the human stays involved (ticket writing, final review) and walks through a real chat-streaming bug end to end: reproduce, diagnose, fix, and re-verify by video.

Advises building each step of a new loop by hand first, understanding what success looks like, before turning it into an automated skill.

Recaps the two loops combined into one master loop, claims the pattern is model-agnostic, then closes with a subscribe ask.
An AI coding agent can safely run unattended in a loop only when 'done' is defined as a specific, machine-checkable state, a recorded successful test or a perfect review score, not a human's gut sense that the output looks right.
“I finally have a workflow where I can literally go to bed with a defined loop and wake up with a finished PR ready to get shipped.”
“If we're gonna be honest with ourselves, most agents suck at design.”
“This loop is going to be successful all the time because the feedback loop, the success state, the desired state is not only easy to check, but easy to identify and easy to state.”
“Read the feedback you get, read the comments that you get, address those comments, push to the PR again, and wait for a review.”
See every word as it's spoken — crank it to 2× and still catch all of it. The same dual-channel trick behind Amazon's Kindle + Audible.
Ras Mic opens with a number that begs a question: how does one person ship 75 pull requests using an AI agent in about a week without manually reviewing all the code? The answer, laid out over the next 17 minutes, is not a smarter model, it's two nested loops that force the agent to prove its own work before a human ever needs to look at it.
A two-stage retry loop where the exit condition for each stage is a machine-checkable state (a recorded successful test, then a perfect review score) rather than a human judgment call.
A named skill that tells the agent to wait for a Greptile code-review score, read the feedback if it's under 5/5, revise the code, resubmit, and repeat until a perfect score, automating what would otherwise be manual back-and-forth PR review.
“Click the link in the description. Go build something beautiful with Framer.”
Woven into the tutorial as an in-story tangent rather than a separate ad break, presented as solving the exact pain point ('most agents suck at design') the video just raised, with a live one-prompt clone demo as proof before returning to the main tutorial.
