Understand this story
On October 26, 2026, Shao Meng relayed the content of a Rob Shocks video, analyzing and comparing three Agent Skill packages: Pocock, Addy Osmani, and the Cursor official plugin pstack. According to the relay, none of the three approaches works for everything: Pocock focuses on whether alignment on what to build is achieved before coding, Addy Osmani covers the complete engineering workflow from Define to Ship, and pstack focuses on proving that changes actually run. The Addy Osmani set has about 25 skills, including commands such as /spec, /plan, /build, /test, /review, and /ship, as well as multiple reviewer personas. Rob Shocks recommends using them in tiers according to change risk; installing the full set takes up context and is prone to accidental triggering. At present, this comparison is seen only in this one relay by Shao Meng, and no other sources have cross-verified it.

Comparing Three Agent Skill Sets: How to Choose Between Pocock, Addy Osmani, and Cursor pstack
Shao Meng relays Rob Shocks' video comparison of the three Agent Skill sets, concluding that no single set works for everything: Pocock focuses on whether you have aligned on what to build before coding, Addy Osmani covers the complete engineering workflow from Define to Ship, and Cursor's official plugin pstack focuses on proving that changes actually run. Addy's set has about 25 skills, including commands such as /spec, /plan, /build, /test, /review, and /ship, plus multiple reviewer personas. Rob recommends using them tiered by change risk; installing the full set consumes context and is prone to accidental triggering.
