Quorum treats diffs as untrusted prompt input, but local agent providers still execute local CLI binaries. Use local providers only in repositories and configs you trust.
- Subprocess provider output is size-capped and terminal-rendered text is sanitized.
- Provider subprocesses receive a minimal environment plus explicit provider secrets only.
- Provider binaries inside the repository are refused unless that provider config sets
allow_project_binary: true. --reportwrites inside the repository by default. Use--allow-report-outside-rootonly when you intentionally want an external report path.
