REA is dangerous with Opus 5.5 It lets your agent inspect apps you have no source for But finding the code is not the same as proving the behavior I broke down how to get from a black box to a build you can actually test ↓

Reverse Engineering with Opus 5.5: From Black Box to Verified Build

How to give a coding agent real analysis tools, keep its claims tied to evidence, and test what it builds Opus 5.5 opens an application you do not have the source for. After a long run, it has a map

I turned my Opus 5.5 into a motion design studio This is f*cking insane... I asked them to arrange a test drive of the Tesla Roadster Drop the PDF below into Opus 5.5 and see what it makes Then read the motion engineering guide below ↓

REA + Opus 5.5 is one of the wildest engineering stacks right now... And most people will use it to generate a confident guess That paid feature isn't magic If you are allowed to inspect it, you can trace its behavior and build your own version one feature → REA evidence → behavior spec → clean-room rebuild → real tests Send this single prompt to Opus 5.5 + REA Then save the article below on becoming a REA engineer

Opus 5.5 + an AI memory stack is an insane reverse-engineering setup Most agents can describe an app. The hard part is proving how one feature behaves, rebuilding it, and not losing the evidence when the chat resets I wrote a 13-page field guide for that exact workflow: Authorized target → Controlled probes → Evidence ledger → Behavior contract → Tested rebuild → Fresh-session verification Send this to your Opus 5.5 ↓
Your agent remembers the deadline It may also remember the one that got replaced More history won't tell it which one still counts I broke down the AI memory stack: what to save, what to load, what to recheck, and when to forget ↓

Agent builders know this loop too well: Call → Parse → Branch → Call again What caught my eye with TypeLLM: The next decision can depend on the last one inside a single request Incident triage → Assess severity → Consider rollback if critical → Draft a status update One API call. Typed results. Less glue code
Chat models return messages. Decision models return decisions. Workflow models execute workflows. TypeLLM introduces the first workflow model. Run an entire workflow in a single API call. Simpler, faster, cheaper. Try it now: typellm.ai/examples/ticket-w…

EntelligenceAI just open-sourced AgentPlay, a local replay tool for coding-agent sessions Files read →Commands retried → Errors hit → Context lost This is f*cking useful... Run it on one old session Self-improving harness starts by seeing what actually happened
Introducing AgentPlay 🚀 The future of coding is self improving coding agent harnesses that help agents avoid making the same mistakes over and over. Turn your existing Claude Code, Codex, Cursor and Copilot sessions into interactive maps and replayable timelines. See what your agent explored, where it failed, what it retried and how it reached the final change Free, local and open source. GitHub: github.com/Entelligence-AI/a…

These prompts for Opus 5.5 and Fable 5.1 are insane for motion engineering I picked 8 GitHub repos that can work as one stack: Remotion, GSAP, Three.js, React Three Fiber, Lottie, SVGO, FFmpeg and Puppeteer The trick: Remotion owns the clock. The other tools only join when a shot needs them Brief → Storyboard → Frame-accurate motion → Render → Visual QA No competing timelines. No installing 8 packages just because they're on the list. No "done" without checking the export Pick Opus or Fable, replace the bracketed fields and send it the prompt ↓
