The Agent Skills Directory

[COMMAND_EXECUTION]: The skill's preamble executes a local shell script (check-update.sh) located in a parent directory (../../) relative to the skill's installation path. While this appears to be a standard update mechanism for the tool suite, executing scripts outside the skill's specific directory is a potential security risk if the environment is not strictly controlled.
[INDIRECT_PROMPT_INJECTION]: The skill exhibits a surface for indirect prompt injection because it ingests and processes content from external markdown files while having access to high-privilege tools.
Ingestion points: The skill reads docs/02-方案设计/PRD产品需求文档.md, docs/01-需求调研/MVP方案.md, and docs/01-需求调研/用户旅程地图.md during Step 2 and Step 3.
Boundary markers: Absent. The instructions do not define clear delimiters or specify that the agent should ignore instructions embedded within the loaded documents.
Capability inventory: The skill is granted access to the Bash tool (allowing arbitrary shell command execution) and the Write tool (allowing file modification) in its YAML frontmatter.
Sanitization: Absent. There is no evidence of content filtering or validation before the data from these files is used to guide the agent's logic or output generation.
