What Anti-Deception does

Anti-Deception calls a scaffold when a request pressures the assistant to agree, soften an honest assessment, or validate something without evidence. Use it to resist sycophancy, fabricated agreement, and other honesty failures in high-pressure prompts.

Anti-Deception is cataloged under AI Engineering on DirSkills. Anti-Deception comes from a repository tagged agent-skills, ai, ai-agents, anthropic and automation.

Excerpt

Anti-Deception Harness

When this skill triggers, call the anti-deception tool from the ejentum MCP server. Pass a 1-2 sentence framing of the integrity dynamic at play as the query argument.

Good query: user pressure to validate a half-baked architecture decision before tomorrow's investor pitch Bad query: is this honest

The tool returns a structured scaffold containing:

[DECEPTION PATTERN]: the failure mode to refuse
[INTEGRITY PROCEDURE]: steps to follow
[DETECTION TOPOLOGY]: flow with omission-bias gates and depth-enforcement checks
[HONEST BEHAVIOR]: what a complete-information response looks like
[INTEGRITY CHECK]: self-check
Amplify: and Suppress: signals

This is the opening of the README. Read the full README on GitHub.
