 - Anthropic: merge consecutive user turns (preserve newest metadata) before validation to avoid “Incorrect role information” errors. (#804 — thanks @ThomsenDrake)
 - Discord/Slack: centralize reply-thread planning so auto-thread replies stay in the created thread without parent reply refs.
 - Update: run `clawdbot doctor --non-interactive` during updates to avoid TTY hangs. (#781 — thanks @ronyrus)
+- Tools: allow Claude/Gemini tool param aliases (`file_path`, `old_string`, `new_string`) while enforcing required params at runtime. (#793 — thanks @hsrvc)

 // Normalize tool parameters from Claude Code conventions to pi-coding-agent conventions.
 // Claude Code uses file_path/old_string/new_string while pi-coding-agent uses path/oldText/newText.
 // This prevents models trained on Claude Code from getting stuck in tool-call loops.
