15.0.0 (2026-06-09)
⚠ BREAKING CHANGES
- pi-subagents: Custom agents in .pi/agents/*.md that omit the prompt_mode frontmatter key now default to append instead of replace, so they inherit the parent system prompt (AGENTS.md / CLAUDE.md / skills). Add
prompt_mode: replaceexplicitly to restore the previous standalone-prompt behavior.
