Claude Code compaction inconsistently retains invoked skills

By PulseAugur Editorial · [1 sources] ·

A recent analysis of Claude Code's compaction behavior reveals inconsistencies in how it retains invoked skills. While the root CLAUDE.md file and its imports are consistently preserved, two out of eight compaction tests failed to re-inject the body of an invoked skill when using the `claude -p --resume` command. This contrasts with compactions run within a single process, which successfully re-attached skills. The study also confirmed that Claude Code preserves typed passphrases within chat summaries and correctly re-injects nested CLAUDE.md files under specific conditions. AI
