Claude Code mods: what developers, designers, and managers can use them for

Claude Code mods: what developers, designers, and managers can use them for

What mods in Claude Code are, how they differ from hooks, and how developers, designers, PMs, QA, and ops could use them. Plus what to check before installing someone else's mod.

cpm 0.3.0: a profile is now an environment, not just an account

A new version of Claude Profile Manager: per-profile MCP servers and settings, separate session history, profile management from the command line, cpm exec for scripts and CI, and an API key check before cloud sync.

What if your agent had an evening — a daily reflection loop instead of summaries

What if your agent had an evening — a daily reflection loop instead of summaries

Claude Code starts every session from zero. What if the agent reflected each evening instead of summarizing? A thought experiment on memory and pruning.

/goal in Claude Code: keep a session running until the condition holds

/goal in Claude Code: keep a session running until the condition holds

Anthropic shipped the /goal slash command. A session-scoped wrapper over a prompt-based Stop hook: you write a condition, a small evaluator reads the transcript after each turn, and the session ends only when it says yes. When to reach for /goal, when for /loop, when for a Stop hook — and why you write the condition for Haiku, not for the main model.

Anthropic Admitted a Month of Claude Code Degradation — Here's What Actually Happened

Anthropic Admitted a Month of Claude Code Degradation — Here's What Actually Happened

From March 4 to April 20, 2026, three concurrent degradation modes ran in Claude Code. Anthropic frames them as bugs — but two of the three were deliberate decisions.

Claude Code and .env files — the certification answer that isn't enough

Claude Code and .env files — the certification answer that isn't enough

The certification question has one correct answer out of four — a PreToolUse hook on Read and Grep. In production, your `.env` still leaks through Bash. A working hook that closes it.

Brain dump over writing — how I dictate feature specs into Claude Code

Brain dump over writing — how I dictate feature specs into Claude Code

Whisprflow replaced my spec writing. I dictate a messy brain dump into Claude Code, the agent turns it into a structured spec and asks whether it understood me. Ten minutes instead of an hour — and a better output.

Claude Code hooks — the complete guide to guardrails that actually work

Claude Code hooks — the complete guide to guardrails that actually work

PreToolUse, PostToolUse, Notification. What Claude Code hooks are, how to configure them in settings.json, and the three patterns I use in every production repo.

Cursor vs Claude Code — an honest comparison after shipping both to production

Cursor vs Claude Code — an honest comparison after shipping both to production

Not a spec sheet. A direct comparison of Cursor and Claude Code based on daily production use — editor integration, agentic workflow, hooks, skills, cost and when to pick each.

git push --force the future — how I presented at Yolk Studio

git push --force the future — how I presented at Yolk Studio

A talk on AI agents in software development. CLAUDE.md, hooks, skills, Skillsmith, git worktrees and real-world case studies — everything I showed at Yolk Studio.

Claude Agent SDK — building production agents without reinventing the loop

Claude Agent SDK — building production agents without reinventing the loop

The Claude Agent SDK gives you the same primitives Claude Code uses — tools, hooks, subagents, permissions. A practical walkthrough of shipping one to production.

Claude Profile Manager: Multiple Accounts, One Machine

Claude Profile Manager: Multiple Accounts, One Machine

Personal subscription, company team, Vertex AI setup — and Claude Code stores everything in one directory. I built a CLI tool that gives each account its own isolated environment.

Skillsmith: Write AI Skills Once, Export Everywhere

Skillsmith: Write AI Skills Once, Export Everywhere

Your team uses Claude, Cursor, and Copilot — and you're maintaining the same coding standards in five places. I built an open-source tool that fixes this with one command.
