Automate a Weekly Workout Log with Claude and Hevy

Every Friday at 10 a.m. ET, a scheduled Claude agent refreshes a living "Hevy Workout Log" document with that week's strength-training data, body measurements, and a progress photo. The automation runs fully unattended, with no human in the loop after the owner sets it up. The agent pulls information from three independent systems: the Hevy fitness-tracking API, a Google Drive photo folder, and the living document. It reconciles those sources against a date range, determines what's new versus already recorded, and writes structured, formatted updates in the correct places. This requires more judgment than a simple script or webhook. The scheduled task starts a fresh agent session every Friday at 10 a.m. ET with the full task specification and API key included in the prompt. The Hevy API is the source of truth for workouts from `GET /v1/workouts` and body measurements from `GET /v1/body_measurements`; both endpoints are paginated. Google Drive holds the "Progress Pics" folder, which the agent searches by file timestamp. Claude Docs, through a Claude Artifact, is the living document: it has one tab for each weekday and a Weekly Summary tab, and the agent edits it in place with structured operations rather than full rewrites. To embed a photo, the agent downloads the Drive file locally, uploads it to the Claude Artifact asset store, converts it to a document-native blob, and references it as a Markdown image. There is no custom backend, database, or glue code. The agent calls each system's API directly and keeps the orchestration logic in its reasoning for that run. Step-by-step: 1. Read the document's current state and find the most recent week already recorded in the Weekly Summary tab. 2. Call the Hevy API and determine which Monday–Friday week has just ended, making sure today's date is past that week's Friday. 3. Check whether that week's row is already in the Weekly Summary table, fully populated, and contains the latest matching photo. If everything is already recorded, there may be nothing to update, but the agent still checks for a newer photo that may have appeared in Drive after the data was written. 4. Pull per-set details for every workout that week, including the exercise, weight, and reps. Compute total daily lifted volume by summing weight × reps for each set on each day. 5. Search the Google Drive photos folder for images timestamped within that Monday–Sunday window. Select the single most recent image, replacing any older photo already embedded for that week. 6. Pull body measurements from the same week and calculate weekly averages for weight and body fat, along with the week's waist reading. Convert units as needed from kilograms to pounds and centimeters to inches. 7. Update the Weekly Summary tab with one row per week, including daily volumes, weekly averages, and the progress photo. 8. Update each weekday tab with a dated section containing the workout name, a per-exercise set-by-set table, and a Total row for summed volume and reps. If no workout was logged, add a note instead. 9. Send the human a plain-language summary every time, describing what changed or confirming that nothing changed, because nobody is watching the scheduled run live. The workflow is idempotent without a database. There is no job-tracking table; on each run, the agent reads the live document, compares dates, and checks whether cells are filled before deciding what to write. Progress photos are not tagged by week, so the agent matches them only by whether their Drive timestamp falls within the Monday–Sunday window. It explicitly selects the most recent match, allowing a better photo taken later in the week to replace an earlier embedded photo. The workflow also handles the multi-hop process required to embed an image in a live document: Drive file to local download, artifact asset upload, document-native blob conversion, and Markdown image reference. If the Hevy API key is revoked, the task stops cleanly and tells the owner to generate a new key and provide it, rather than failing silently or looping. Because the workflow runs on a schedule without anyone watching, its specification requires a notification every time, including when nothing changed. This keeps the automation auditable even when it performs no updates.

Built a complete, free iOS cognitive training app (AllegraMente) solo with Claude Code - 11 exercise areas, 5 languages, no tracking

I built AllegraMente, a complete, free iOS cognitive training app, solo with Claude Code. It includes 11 exercise areas, 83 articles in five languages, and no tracking. My workflow starts with a new feature or content idea, a new exercise type, or an in-depth article about how memory works. Planning and execution stay separate, and the instruction document serves as the contract. Because everything is specified upfront, Claude Code almost never goes off track. Step-by-step: 1. I plan the feature with Claude in chat, define the data models and UX, and fact-check every scientific claim against primary sources before writing anything. 2. I package the result into one self-contained Markdown instruction document containing file paths, specifications, localization keys for all five languages (IT/EN/ES/FR/DE), edge cases, and acceptance criteria. 3. I create a Git restore point. 4. I give the document to Claude Code, which implements the feature end to end using SwiftUI, SwiftData, and MVVM. 5. A small script sends me a Telegram notification when the task is complete. I review the diff and test the app on a device. 6. I ship by creating an archive with `xcodebuild` and uploading it to the App Store with Transporter. This process is how I shipped 11 exercise areas, 83 articles in five languages, and a complete editorial system as a solo developer.

AI-Assisted Mobile Game Development Workflow for Bubble Grotto

I built Bubble Grotto, a skill-based arcade game for mobile devices, using AI as a development partner. The concept is deliberately simple: start with a small bubble, grow it, navigate through a cave filled with hazards, and decide when to escape. The larger the bubble becomes, the greater the potential reward—but the harder it becomes to manoeuvre safely. The aim was to create the classic “one more go” experience: controls that can be understood almost immediately, with gameplay that becomes progressively harder to master. The interesting challenge was that building a game is very different from implementing a list of features. The code can work perfectly and the game can still be no fun. Timing, movement, difficulty, visual feedback, and risk versus reward all have to feel right when somebody actually plays it. Step-by-step: 1. I used AI to discuss how the core concept should work, including bubble growth, movement, hazards, progression, scoring and rewards, and the escape mechanic. 2. Rather than designing the entire game upfront, I used AI-assisted development to turn each mechanic into working code and get it onto a real device as quickly as possible. 3. Once a mechanic existed, I tested it myself. I checked whether movement was responsive, whether the bubble grew too quickly, whether obstacles were fair, whether escaping was too easy, and whether failure made me want another attempt or simply became frustrating. 4. I brought those observations back into the AI workflow, identified the relevant behavior or code, made targeted changes, and tested again. 5. Once the core loop felt enjoyable, I refined the interface, visual feedback, progression, and presentation instead of allowing cosmetic work to hide weak gameplay. This produced a development loop of: idea → mechanic → playable build → play-test → adjust → repeat The final result is Bubble Grotto, an arcade game with simple controls but increasingly demanding skill-based gameplay. Players grow their bubble while navigating hazards and must balance risk against reward by choosing the right moment to escape. One of the most useful things I learned is that AI can dramatically accelerate game development, but it cannot replace judgment about whether something is enjoyable. AI can help create a mechanic, investigate why it behaves incorrectly, and implement changes extremely quickly. The human still has to play the game and decide: is this actually fun? That combination allowed me to move rapidly from a simple game idea to a functioning mobile game while spending far more of my time experimenting with gameplay than wrestling with implementation.
