neonwatty Bundle Trust Builder 2Analyzes web apps for free-value trust-building opportunities — features, tools, and offerings that demonstrate genuine utility before asking for commitment. Use this when the user says "trust builder", "trust audit", "find free offerings", "free value analysis", "trust building opportunities", or "how can I build trust with users".

Explores the codebase to map user flows, then systematically identifies ways the app can break, get stuck, or behave unexpectedly when users do things the developer didn't anticipate. Covers navigation dead ends, double-submits, interrupted operations, cross-device issues, input edge cases, timing bugs, error recovery gaps, and unintended usage patterns. Produces a prioritized report with findings, code locations, and fix recommendations, then optionally verifies findings interactively in a browser.

Explores the codebase to map the economic surface area (pricing tiers, usage limits, free trials, costly resources), then generates abuse cases where user behavior — intentional or not — could break assumptions, bypass limits, amplify costs, or corrupt state. Produces a prioritized markdown report with findings, code locations, and fix recommendations, then optionally verifies findings interactively in a browser.

nangongwentian-fe Bundle Post Implementation Review Gate 2Use after completing a non-trivial implementation and before final handoff, especially for public API/schema compatibility, database or migration work, authentication/security, deployment/configuration, concurrency or data integrity, algorithmic or control-flow complexity, cross-module refactors, runtime lifecycle, and rendered UI behavior. Make sure to invoke this skill even when the user asks only to implement or fix something and does not explicitly request review. Risk-classify the completed change, use a new isolated read-only subagent for review-triggering changes when delegation is allowed, otherwise perform and disclose a local fallback, verify findings, fix authorized in-scope defects, rerun relevant checks, and report residual risks. Do not use for planning, answer-only or diagnosis-only tasks, trivial text edits, mechanical formatting, or tasks with no implementation-artifact change.
