The Agent Skills Directory

[PROMPT_INJECTION]: The 'FINAL STEP' section in SKILL.md uses a simulated user quote ('It isn't perfect enough...') to programmatically force the agent into a refinement loop, which overrides the actual conversational state.
[EXTERNAL_DOWNLOADS]: The skill instructs the agent to 'Download and use whatever fonts are needed,' which encourages interaction with arbitrary remote sources without any domain whitelisting or security validation.
[PROMPT_INJECTION]: The skill exhibits vulnerability to indirect prompt injection due to its processing of untrusted user-supplied 'conceptual threads.'
Ingestion points: User-provided 'subtle input' and niche references described in the DEDUCING THE SUBTLE REFERENCE section of SKILL.md.
Boundary markers: Absent; there are no delimiters or instructions to treat the user input as non-executable data.
Capability inventory: The skill is explicitly tasked with creating .md, .pdf, and .png files.
Sanitization: Absent; no validation or filtering of user-provided input is specified before it is integrated into the design process.
