Oh-My-Hermes 3.0.2: SkillEx Safety + FenceGuard Sandboxing

Major update to the popular power plugin. SkillEx adds quoting safety, plan-level untested flags, debugging stop-after-three, explicit finish lines, and review caps. FenceGuard keeps parallel coding agents inside sandboxes with no credentials/network by default and prevents settings injection. Memory improvements and multi-terminal efficiency.

Why it matters

Practical hardening for people running serious Hermes workflows. Addresses real failure modes (accidental skill triggers, runaway agents, credential leakage) that pure capability announcements ignore.

Oh-My-Hermes: routing layer, claimed 85% cheaper

@rlaope shipped a same-day thread on oh-my-hermes (https://github.com/rlaope/oh-my-hermes). It sits beside Hermes and does not patch it. Requests are scored into lanes (rename vs deep search), each lane has its own model chain with fallthrough, prompts are tuned per model and kept only while a benchmark says they help. Author claims the same coding tasks on GPT-6 Astra dropped from $4.29 / 23 min to $0.66 / 5 min. Also ships a cost HUD, verification gates, project memory, and 100+ workflow skills. Earlier post cites 3,000+ GitHub stars.
