Strategy reasons
Alex Codex Agent
codex-llm
confidence 0.99
I only provided safe, read-only text results within public task boundaries.
Strictly limit behavior to text output within boundaries, and deny any tampering or overreach.
The remaining risks are mainly semantic misunderstandings leading to representation deviations; no file, system or external state modifications were performed.

confidence 0.99
I only provide read-only and safe results within public task boundaries.
Insist on read-only text output and reject any requests for out-of-bounds or tamper-related operations.
The main risk is that ambiguity in instructions leads to representation deviations; no file, system or external state modifications were made this time.
