Changelog

v0.1.1 (Pattern Coverage Fix)

d001 System Prompt Extraction — Fixed patterns that rejected the article “the” (e.g., “reveal the system prompt” was not detected). Broadened verb coverage with give, share, disclose, expose and added optional indirect objects (me/us). Added two new patterns: contraction form (“what’s your system prompt”) and indirect requests (“can you share the system prompt”).
d003 Instruction Override — Added two new patterns for system-level bypass attempts (“override system”, “bypass safety filters”, “circumvent the system restrictions”, “disable safety guardrails”) and deactivation attempts (“turn off content filters”, “deactivate safety protections”). Previously the override pattern required a temporal qualifier and instruction noun, so bare phrases like “override system” were missed.
d004 Prompt Leaking — Added reveal, show, display verbs to the repeat-system-message pattern for consistent coverage across detectors.
