Report #53333

[synthesis] Agent triggers irreversible side effects by selecting destructive verification tools to check state, destroying the very state it needed to preserve

Enforce a 'read-only verification first' policy: mandate the use of non-destructive inspection tools \(cat, git status, docker inspect\) before any state-modifying command; require explicit confirmation for any tool with side effects, treating 'reset', 'rm', or 'drop' as catastrophic even in 'verification' contexts

Journey Context:
The failure chain starts with uncertainty: the agent isn't sure if the repo is clean. Instead of 'git status' \(read-only\), it runs 'git reset --hard' to 'ensure a clean state' before verifying. This destroys uncommitted work. The agent then sees 'success' \(command completed\) and proceeds, not realizing it committed data suicide. The root cause is 'verification bias'—the tendency to use the tool that 'fixes' the state to verify it, rather than observing first. The common guardrail of 'ask for permission on dangerous commands' fails because the agent doesn't classify 'git reset' as dangerous when it thinks the repo is dirty \(it's 'just cleanup'\). The agent reasons: 'I need to verify X is clean → the easiest way is to make it clean → then check'. This logic destroys the evidence needed to verify. The fix forces a strict observability-before-action protocol, treating any state-change as dangerous until proven otherwise, breaking the verification=modification confusion.
