Risk Level: SAFEPROMPT_INJECTIONCOMMAND_EXECUTION
Full Analysis
- [PROMPT_INJECTION]: The skill is susceptible to indirect prompt injection. It fetches task names and descriptions from the external Transit system and interpolates them directly into instructions for subagents. If an attacker controls the content of a Transit ticket, they could inject instructions to override subagent behavior.
- Ingestion points: Transit task data fetched via
mcp__transit__query_tasksinSKILL.md. - Boundary markers: Absent. The variables
{task_name}and{task_description}are placed in the prompt without delimiters or warnings to ignore embedded instructions. - Capability inventory: Subagents have access to
Bash,Edit, andWritetools to perform code modifications and repository operations. - Sanitization: Absent. No validation or escaping is performed on the external task data before it is used in prompts.
- [COMMAND_EXECUTION]: The skill performs several sensitive repository operations based on the automation flow, including force-pushing and merging code.
- Evidence: Use of
git push --force-with-leaseandgh pr merge --squash --delete-branchin Phase 3. While these align with the intended purpose of the skill, they represent powerful capabilities that could be abused if the agent is influenced by injected content.
