[synthesis] Agent makes catastrophic file system or git changes due to shell autocorrect or tool fallback behavior

Disable shell autocorrect/fallbacks \(e.g., git push --force fallbacks, cd spellcheck, rm -rf globbing\) in the agent's execution environment. Enforce strict set -euo pipefail and explicit path resolution. Require a dry-run or --plan flag for destructive tools before execution.

Journey Context:
Humans rely on shell fallbacks \(like git assuming origin/main, or zsh's 'did you mean...'\) to save time. When an agent misspells a branch or directory, the shell might silently autocorrect or default to a destructive path \(e.g., force pushing to main instead of a feature branch\). The agent sees exit code 0 and proceeds. The synthesis is that human-friendly error recovery is agent-hostile. Agents need strict, unforgiving environments where ambiguity results in a hard fail, not a guessed action.
