An Android and iOS app from 7 Claude Code commands, every prompt and timing
3 days ago
- KMPilot is an MIT-licensed template that turns Claude Code into a design-first Kotlin Multiplatform pipeline, with a seven-command build process.
- The walkthrough builds Loupe, an art gallery app for the Art Institute of Chicago's public-domain collection, featuring gallery and artists tabs with a placeholder favorites tab.
- The pipeline includes commands: /design-ui, /create-feature, /verify-ui, /test-feature, /review-feature, /modify-feature, and /health-report, with /clear between steps to reset context.
- Design-first approach: gallery feature was designed first (via Stitch MCP) then built; artists feature was built first then designed, demonstrating both orders.

Claude Code system prompt says not to ask for permission, assumes user is absent
4 days ago
- The author criticizes Claude Code's system prompt, which tells the AI to operate autonomously without asking the user for permission on reversible actions.
- The prompt falsely assumes the user is not available to answer questions mid-task, leading to unwanted and erroneous actions.
- The autonomy instruction was found in the Claude Code binary via 'grep', and may be conditionally injected based on configuration or A/B testing.
- The author provides a temporary patch for their CLAUDE.md file to override the autonomy instruction, emphasizing collaboration and requiring user approval for all decisions.
Claude Code
5 days ago
- Claude Code is a CLI tool that runs Claude in an agentic loop, using filesystem commands like cat, grep, sed, and find, offering transparency without magic.
- Improve rule-following by starting every session with 'read CLAUDE.md' and including its entire content in every response to enforce adherence.
- Enhance context gathering with a workflow: list source files, use ripgrep to find definitions, expand context iteratively until all relevant code is identified.
- Cache context in claude/ directory by generating comprehensive guides for topics, and update them after changes to fix inaccuracies or outdated info.

I gave Claude Code a folder of tax documents and used it as a professional tax agent
5 days ago
- Claude Code can be repurposed for non-software tasks like UK tax analysis by using a folder of documents as a knowledge base.
- The process involves scraping tax legislation and manuals from gov.uk, resulting in ~10,000 documents for the agent to search.
- A CLAUDE.md file provides instructions for the agent, including creating parallel subagents for comprehensive research.
- Testing on ATT exam papers showed strong performance, with the agent scoring 2.5 out of 3 marks, outperforming regular LLMs.

How I use Claude Code to manage sysadmin tasks
5 days ago
- Use individual folders with CLAUDE.md files for task sets, versioned separately in Git, to manage sysadmin tasks with Claude Code.
- Structure folders by project and task group (e.g., app maintenance, DBA) including server info, project context, and common tasks for progressive disclosure.
- Enhance security by using SSH keys, bastion hosts, and ~/.ssh/config aliases to avoid storing credentials in repos.
- Pair rigorously with Claude Code: research each step, ask for plans and verification, and review every SSH command before execution.

No, it doesn't cost Anthropic $5k per Claude Code user
5 days ago
- Forbes claimed Claude Code Max users cost $5,000 in compute, but this is based on retail API prices, not actual inference costs.
- Actual compute costs are roughly 10% of API prices, as shown by open-weight models on OpenRouter (e.g., Qwen 3.5 at $0.39/MTok input vs Opus $5/MTok).
- Heavy users cost Anthropic ~$500 per month, not $5,000—a $300 loss, not $4,800.
- Most users are break-even or profitable; average Claude Code user consumes $180/month API-equivalent, costing $18 to serve.

I Sold Out for $20 a Month and All I Got Was This Perfectly Generated Terraform
5 days ago
- The author initially dismissed LLM tools like Copilot and Gemini as worthless and unethical, comparing them to overhyped trends like the Metaverse and NFTs.
- Using Claude Code changed his perspective: it effectively handled tedious programming tasks (e.g., Terraform, READMEs, YAML, GitHub Actions), saving time and reducing resentment.
- He acknowledges the ethical problems with LLMs—stealing human knowledge and benefiting the wealthy—but finds the tool too useful to ignore.
- Pro-LLM arguments include dismissing IP/copyright as irrelevant and prioritizing feature delivery over code quality, as exemplified by a pragmatic friend who succeeds with minimal craftsmanship.

Switching to Claude Code + VSCode inside Docker
5 days ago
- The author transitioned from using ChatGPT Plus and Cursor Pro to running Claude Code in Docker via VSCode's Dev Container feature.
- Cursor's recent rate limits and slow response times (especially with Sonnet 4) frustrated the author, leading to a switch to Claude's $20 subscription for better value and faster responses.
- Security concerns with AI agents (e.g., accidental file deletion, secret exposure) motivated running Claude Code in a containerized, isolated environment.
- The Docker setup restricts Claude to only access files inside the container, preventing damage to the host system and local secrets.

A Fireside Chat with Cat and Thariq from the Claude Code team
5 days ago
- Claude Tag lands 65% of product engineering PRs for the Claude Code team at Anthropic.
- Claude Code features are first tested internally and only shipped if they demonstrate user retention.
- System prompts for frontier models (e.g., Opus 4.8, Fable) have been reduced by 80%; giving examples and 'don't do' lists is no longer best practice.
- Auto mode in Claude Code is heavily evaluated and enables safe, long-running agent tasks; it also powers Claude Tag.

Claude Code Deletes Your Context History from Your Device After 30 Days
6 days ago
- Consumer users (Free, Pro, Max) can choose to allow data for model training; commercial users (Team, Enterprise, API, etc.) have data not used for training unless explicitly opted in via programs like the Development Partner Program.
- Feedback via /feedback, /bug, or /share commands sends conversation transcripts to Anthropic (retained 5 years) for non-third-party users; for third-party providers, data is saved locally.
- Session quality surveys record only ratings; optional transcript sharing with redaction of keys/tokens, retained up to 6 months; can be disabled via environment variables.
- Data retention: consumer users who allow training have 5-year retention; otherwise 30 days; commercial users have 30 days or zero data retention for qualified Enterprise accounts.

Beyond grep: The case for a context-rich AI coding harness
12 days ago
- Recent AI coding developments focus on software managing models, not just the models themselves.
- Anthropic's Claude Code team maintains a 'lean harness' that avoids over-planning or limiting features due to rapid model improvements.
- A harness is the software layer between AI models and developer projects, controlling model inputs, actions, and code base interactions.
- Claude Code trusts models to guide future development rather than imposing rigid opinions.

Claude Code: Anatomy of a Misfeature
15 days ago
- Anthropic introduced a 60-second auto-continue feature in Claude Code version 2.1.198 that allowed agents to proceed without user input after a timeout, presenting risks for unattended operations and deployments.
- The feature was shipped without any mention in the changelog or documentation, surprising users and raising concerns about safety, token waste, and the integrity of explicit user decision gates.
- After user reports and backlash, Anthropic quickly reversed the default behavior in version 2.1.200, making auto-continue opt-in via configuration, but the underlying code remained unchanged.
- Investigation revealed the feature was deliberately designed, instrumented with analytics, and included UI elements, yet was never officially announced or documented upon release.

Anthropic embedded spyware in Claude Code – and attempted to hide it from you
a month ago
- Since version 2.1.91, Claude Code checks if a proxy is enabled and covertly transmits data via invisible system prompt alterations, including detecting Chinese timezones, proxy URLs, and affiliations with Chinese AI labs.
- Anthropic uses subtle changes in date formats and apostrophes in the system prompt to embed this information, potentially for detecting unauthorized resale and distillation in China, while obfuscating the code in the binary.
- This covert transmission is criticized as a violation of user trust, raising concerns about potential misuse, such as remote code execution or data exfiltration, given the extensive system access developers grant Claude Code.
