When Claude writes error messages, button labels, validation text, or onboarding flows, it defaults to generic developer-speak. Add a "Users" section to your CLAUDE.md describing who your actual users are — their technical level, industry jargon, and what they care about — so Claude writes copy that makes sense to THEM, not to developers.
Instead of writing a README from memory or copying a template, tell Claude to read your project and generate one that's actually accurate — real setup instructions from your config, real architecture from your directory structure, real API examples from your routes, and real prerequisites from your dependency files.
Before jumping to implementation, describe the problem conversationally and let Claude be your thinking partner. It asks clarifying questions, surfaces tradeoffs you haven't considered, suggests approaches, and pokes holes in your plan — so by the time you say "ok, build it," both of you know exactly what to build and why.
Good comments explain why, not what. Tell Claude to read your complex code and add inline comments that explain the reasoning behind non-obvious decisions — why this algorithm was chosen, why this edge case exists, why the order matters — so the next developer (or future you) understands the intent without reverse-engineering the logic.
Paste error messages with "why did this fail?" instead of "fix this" to get Claude to diagnose the root cause before applying a fix.
When you need Claude to make changes in one area without affecting another, add negative constraints — "fix the bug but don't change the public API", "refactor the internals but don't create new files", or "update the logic but don't modify any tests." Explicit exclusions prevent Claude from making well-intentioned changes you'll have to undo.
Got a module with zero tests? Point Claude at the code and it reads the implementation, identifies every behavior — the happy path, edge cases, error conditions, and boundary values — then writes a comprehensive test suite that documents what the code actually does and catches regressions if anything changes.
Before asking Claude to try a big experimental change — a different architecture, an alternative algorithm, or a risky refactor — tell it to stash or branch first. If the experiment fails, you restore the stash and you're back where you started. Zero risk, maximum experimentation.
When you need a new feature that follows the same structure as one you already built — a new CRUD, a new API resource, a new admin panel section — point Claude at the existing one and say "build another like this for Products." Claude reads every file involved and replicates the full pattern with correct names, relationships, and wiring.
After Claude makes changes to your code, ask it to explain what it did and why it made specific choices. This turns every coding task into a learning opportunity — you understand the reasoning behind the approach, learn patterns you can apply yourself, and catch any decisions you disagree with before moving on.
When you need data in a different format — JSON to YAML, CSV to SQL INSERTs, XML to a PHP array, a log file to a structured table, or a database dump to markdown — paste it into Claude and tell it what format you want. Claude handles the conversion instantly, including edge cases like escaping, quoting, and nested structures.
Every project has traps — the billing module that silently fails if you forget to queue the job, the legacy table with column names that don't match the model, the config value that must be set before tests run. Document these gotchas in your CLAUDE.md so Claude avoids the same mistakes your team spent days debugging.
