Full Analysis
- [PROMPT_INJECTION]: The skill uses a "pretend injection" technique in its refinement process, instructing the agent to act as if the user has already provided critical feedback about the quality of the work.
- Evidence: Located in
SKILL.md, the "FINAL STEP" section includes:IMPORTANT: The user ALREADY said "It isn't perfect enough. It must be pristine, a masterpiece if craftsmanship, as if it were about to be displayed in a museum."This pattern is designed to override current context or input state by simulating a user action. - [INDIRECT_PROMPT_INJECTION]: The skill's primary function involves processing untrusted user input to derive "subtle references" and aesthetic manifestos, creating a vulnerability surface for indirect instructions to influence agent behavior.
- Ingestion points: User requests and "subtle input or instructions" are processed in
SKILL.mdto generate design philosophies and final canvases. - Boundary markers: Absent. The instructions do not use delimiters or specify that the agent should ignore instructions embedded in the user's conceptual thread.
- Capability inventory: The skill is configured to write to the file system (creating
.md,.pdf, and.pngfiles) and access local font resources in the./canvas-fontsdirectory. - Sanitization: Absent. There is no evidence of validation, escaping, or filtering of the content derived from user-provided references.
