Full Analysis
  • [REMOTE_CODE_EXECUTION]: The skill makes extensive use of the command npx @fission-ai/openspec@latest in its operational steps as documented in cflx-apply.md and cflx-archive.md. This command downloads and executes external code from the NPM registry at runtime. The organization @fission-ai is not a trusted vendor and is not associated with the skill author 'tumf'.
  • [EXTERNAL_DOWNLOADS]: Operational instructions and reference files recommend using npx to fetch and run tools or updates from the public @fission-ai repository at runtime.
  • [PROMPT_INJECTION]: The skill is explicitly configured to bypass human-in-the-loop safety measures. Instructions such as 'CRITICAL
  • This skill CANNOT ask questions', 'NO QUESTIONS', and 'All decisions must be made autonomously' prevent the agent from seeking clarification if it encounters ambiguous or malicious instructions within its context.
  • [PROMPT_INJECTION]: The skill is susceptible to indirect prompt injection due to its automated ingestion of external markdown files without validation.
  • Ingestion points: Files located at openspec/changes/<change-id>/proposal.md, design.md, and tasks.md are read and followed as instructions for implementation.
  • Boundary markers: There are no markers or system instructions provided to differentiate between the skill's hardcoded instructions and untrusted content within the change proposal files.
  • Capability inventory: The skill has the capability to modify files, execute shell commands, run local scripts, and invoke the npx package manager.
  • Sanitization: Content from the proposal files is not sanitized or validated before being interpreted as a task sequence by the agent.
  • [COMMAND_EXECUTION]: The skill executes local Python logic via scripts/cflx.py and utilizes shell commands like git status to manage the local workspace and verify implementation states.
