I design and build apps, the backends behind them, developer tools and, lately, AI agents. Sometimes the launch film too. This reel is some of it.

Still curious.

Featured build · 2026 · Live, and free to play

Hit. Fly. Repeat.

A stickman brawler where the hit is the whole game.

Every hit is told as loudly as it landed, from a dry tak to a BOOM that stops the fight. It runs in the browser on a fixed 120 Hz simulation, and the server checks every leaderboard run by replaying it. I built the game, its print shader, the sound, the Rust backend and the trailer.

AgenticRoutines

The cache for your agent’s browser work.

Coding agents drive a browser one step at a time: read the page, think, act, repeat, and pay for all of it again tomorrow. This records what the agent did, lets the agent tidy it into a routine, and replays it as one tool call with no model. Before every step it checks the page, and it stops before anything you cannot undo.

agenticroutines.arunprakashg.com Read why I built it

Free and open source. Works with Claude Code, Codex, GitHub Copilot and OpenCode, in Chrome, Edge and Firefox. The repository opens soon.

A routine replaying in a browser. The page glows along its edges, a cursor moves to each field, and the side panel counts the steps as they finish with no model calls.
Replaying: step 2 of 6, no model calls
A replay waiting before its last step. The page glows amber and the side panel asks whether to start the rollout, with Stop and Start rollout buttons.

Cost and time of one long release form, Claude Sonnet 5.5 by hand against a saved routine. Median of 5 runs each, a small sample.

  1. 01 · RecordEverything your agent does in the browser is recorded on your computer. Nothing leaves it.
  2. 02 · RefineThe agent decides whether the task will repeat. If so it turns typed values into parameters and swaps click-throughs for a direct address, then tests the draft.
  3. 03 · ReplayA saved routine appears as one tool. Each step checks the page structure, then the element, then a screenshot crop. A changed step goes to the agent once, and the fix is saved.
  4. 04 · PauseA replay stops before a step that publishes, pays or deletes. An edit cannot remove that pause.

Open source · Claude Code plugin · MIT

Plan in waves. Build in parallel.

Each phase gets its own subagent and git worktree, on the cheapest model that can do the job.

$ claude plugin marketplace add ArunPrakashG/wave-planning$ claude plugin install wave-planning@arunprakashg-plugins

Example · a notes app, 7 phases

Seven phases. Run one by one, they take seven steps. Grouped into waves, they take three, and each wave is checked before the next one starts. Same work. Less waiting.

My other build.

The machine this reel was made on.

I love building PCs. This is the one on my desk: I put it together myself, it runs CachyOS with Hyprland, and it ran the benchmarks in my notes.

    Prompt Injection and What a Browser Cache Must Refuse

    A tool that replays an agent's browser work reads websites and runs routines other people wrote, and both can contain text meant for the agent. What Agentic Routines does about it, the limits the extension holds whatever a page says, and what it cannot cover.

    How an Agentic Routines Replay Checks the Page Before Every Step

    A replay with no model has to know when the page is no longer the one it recorded. Three checks run in order before each step, a changed step goes to the agent once, and a few edits are refused whatever the agent asks for.

    Agentic Routines: A Cache for Your Agent's Browser Work

    Coding agents drive a browser one step at a time and pay for the whole run again tomorrow. Agentic Routines records the run, lets the agent tidy it into a routine, and replays it as one tool call with no model. Why I built it and the numbers from a small benchmark.

    Generative UI Without HTML: Letting the Model Design in a Shader

    I wanted Claude to design anything, not fill in a component catalog. I tried a small language, then free-form HTML in a sandbox, then a single GLSL fragment shader with compile errors and a rendered frame fed back to the model. What each attempt got right, why I dropped it, and what I haven't measured.
