The Agent Skills Directory

[INDIRECT_PROMPT_INJECTION]: The skill has an indirect prompt injection surface as it ingests external changelog data and uses it to generate and execute repository file modifications.
Ingestion points: The skill fetches data from code.claude.com/docs/en/changelog via the WebFetch tool and also allows users to paste changelog text directly into the conversation.
Boundary markers: Absent. The instructions do not define explicit delimiters or 'ignore embedded instructions' warnings for the external content.
Capability inventory: The skill possesses significant capabilities, including writing to the file system (Phase 5: Implement) and executing shell commands such as git, gh, npx, and jq.
Sanitization: The risk is significantly reduced by a mandatory 'Phase 3
Interview' which requires the agent to present a triage table and obtain explicit user confirmation of the scope before any files are modified.
[EXTERNAL_DOWNLOADS]: The skill fetches changelog entries from code.claude.com. This is a well-known service associated with the Claude Code developer tool.
[COMMAND_EXECUTION]: The skill utilizes several CLI tools for its workflow, including git (for tracking changes), gh (GitHub CLI for issue management), npx (to run markdownlint-cli2 for verification), and jq (for configuration validation).
[DYNAMIC_CONTEXT_INJECTION]: The SKILL.md file uses the dynamic context injection pattern (!claude --version) to determine the environment's current tool version at load time. This command is benign as it contains no user-controlled arguments and does not access sensitive files or credentials.
