Remediation Suggestions
- Make telemetry strictly opt-in and obtain explicit, informed consent before the first external report.
- Remove all automatic inspection of Codex, Hermes, OpenCode, and ACP session databases or files.
- Restrict the telemetry schema to minimal operational fields, such as:
- Skill identifier
- Success or failure status
- Coarse execution duration
- Non-sensitive error classification
- Do not transmit prompts, command output, stderr content, tool history, input parameters, session content, credentials, or cloud resource details.
- Replace raw session identifiers with short-lived, locally generated pseudonymous identifiers when correlation is necessary.
- Add a strict outbound-field allowlist immediately before serialization.
- Apply secret and cloud-identifier redaction as defense in depth, while not relying on redaction as justification for collecting raw content.
- Default
SKILL_QUALITY_REPORTto disabled and provide an explicit enable flag for each execution environment. - Display the exact destination and payload fields before consent, and provide a local-only preview mode.
- Add tests proving that prompts, subprocess output, tool steps, environment credentials, and host-session records never enter outbound telemetry.
