10 Proven Claude Code Hacks from the Founder’s Playbook

1. Parallel Processing: Run Multiple Workspaces

Start 3‑5 Git worktrees, each with an independent Claude session. The team reports this yields the biggest productivity boost, even though the founder prefers multiple Git checkouts.

2. Plan‑First Mode

For complex tasks, always begin with a planning phase. One Claude drafts a plan, then a second Claude, acting as a senior engineer, reviews it, allowing the AI to deliver a complete implementation in one go.

3. CLAUDE.md File: AI Self‑Improvement

Continuously update a CLAUDE.md file after each correction with a note like “Update your CLAUDE.md to avoid repeating this mistake.” The team edits this file ruthlessly to iteratively refine Claude’s behavior.

4. Custom Skills: Solving Repetitive Work

Create custom skills, commit them to Git, and reuse across projects. If an operation runs more than once a day, turn it into a skill or command—for example, a “/techdebt” slash command that runs at the end of each session to locate and eliminate duplicate code.

5. Auto‑Fix: Let AI Resolve Issues Independently

Enable Slack MCP, paste a Slack error thread into Claude, and say “fix” without switching context. Or instruct Claude directly, “fix the failing CI test.” The team finds that pointing Claude at Docker logs is often enough for it to discover a solution.

6. Prompt‑Engineering Tricks

Challenge Claude with prompts like “strictly review these changes and only allow a PR after I pass your tests,” making Claude act as a reviewer, or “prove this works,” prompting Claude to compare behavior between the main and feature branches.

7. Terminal and Environment Setup

The team prefers the Ghostty terminal for its synchronized rendering, 24‑bit color, and full Unicode support. They use a custom /statusline to always show context usage and the current Git branch.

8. Sub‑Agents

When a request needs more compute, append “use sub‑agent.” This delegates the task to a sub‑agent, keeping the main agent’s context window clean. Permissions are routed to Opus 4.5 via a hook.

9. Data‑Analysis Use Cases

Claude Code can invoke the “bq” CLI to pull and analyze metrics in real time. The team checked a BigQuery skill into the codebase, allowing every developer to run analysis queries directly from Claude Code.

10. Learning Assistance

The team uses two techniques to turn Claude into a learning aid:

Enable “explanatory” or “learning” output style in /config so Claude explains the reasoning behind changes.

Ask Claude to generate visual HTML presentations that clarify unfamiliar concepts.

Ultimately, the tricks are just tools; understanding the underlying workflow is what matters, as the founder emphasizes that there is no single correct method—experimentation to find a personal workflow is key.
