Common Claude Code Failure Patterns

Most bad Claude Code sessions fail in predictable ways.

Kitchen-sink sessions

One task turns into unrelated questions, then back to the first task. Context fills with irrelevant details.

Fix: use /clear between unrelated tasks.

Claude gets something wrong, you correct it, and it keeps carrying the failed approach forward.

Fix: after two failed corrections, /clear or /rewind and write a better prompt.

The project instructions are so long that the important rules get lost.

Fix: prune anything Claude can infer, anything generic, and anything that belongs in docs or a skill.

Claude produces plausible code, but no test, build, linter, or screenshot proves it works.

Fix: include the verification command in the prompt and ask for the final output.

“Look into this” causes Claude to read too much of the repo and burn context.

Fix: scope the investigation or use subagents for broad research.
