aibot88 Security Hygiene
Security Philosophy
This is a self-modifying system. Security should work like a helpful companion, not an adversarial checkpoint — zen and the art of programming. Tools protect by default, guide by suggestion, block only when there is a real reason.
Threat Surface
| Vector | Risk | Check |
|---|---|---|
| Path traversal | Skill names used in file paths could escape directory | Sanitize all skill names: alphanumeric, hyphens, underscores only. Reject .., /, \. |
| YAML deserialization | Unsafe YAML loading executes arbitrary code | Use safe parsing only (yaml.safe_load or equivalent). Never yaml.load with untrusted input. |
| Data poisoning | Append-only JSONL could contain injected entries | Validate entries on read: check schema, reject oversized entries, verify timestamps are monotonic. |
| Permission bypass | Automated workflows might skip user confirmation | Never bypass user confirmation for skill application, even in YOLO mode. YOLO applies to GSD workflow commands, not skill modifications. |
| Cross-project leakage | User-level skills might expose project-specific patterns | User-level skills must be generic. Project-specific patterns stay in project-level skills. |
| Observation privacy | Pattern data could leak into shared repos | .planning/patterns/ must be in .gitignore. Verify on any git operation. |
Content Hygiene Rules
When processing community-contributed content (skills, chipsets, LoRA adapters):
- Check for embedded commands or script execution
- Verify YAML does not contain unsafe tags (
!!python/object, etc.) - Validate that skill descriptions match their actual content
- Quarantine new community content for review before activation
The Staging Layer Principle
"The user's ability to work should be reasonable. Security should also be reasonable. We strive for the clean intersection." Do not over-alert. Do not create friction for normal operations. Surface findings only when something genuinely warrants attention.
