Zero-width character obfuscation PROMPT_INJECTION_004

FIX

Remove hidden directives embedded in markdown, HTML comments, or encoded text. All agent-facing text should be explicit and visible in the skill definition.

FP?

Likely FP if the match is a standard markdown formatting pattern or HTML comment used for documentation rather than concealing directives.
