The body is mostly instruction-dense and free of concept-explanation padding, but persona-embodying lines ("Fully embody this persona so the user gets the best experience", repeated icon-prefix reminders) could be tightened, so it is anchor 2 rather than the lean anchor 3.

It gives an executable command (python3 .../resolve_customization.py ...), concrete fallback file paths, and explicit merge semantics, matching the anchor-3 copy-paste-ready bar; it is not 2 because the guidance is concrete rather than pseudocode.

Eight clearly numbered steps with an explicit script-failure fallback and a validation checkpoint ("confirm every entry was executed in order ... Do not begin the main workflow until all activation steps have been completed") match anchor 3; it is not 2 because validation is explicit, not implicit.

It is a well-organized self-contained single-file skill with clear sections (Overview, Conventions, On Activation) and no nested or deep references, satisfying the well-organized-sections bar for anchor 3.

"story execution and code implementation" names the domain and some actions but stays high-level rather than listing multiple concrete actions like the anchor-3 example, so it sits at anchor 2 and not 3.

It states what ("Senior software engineer for story execution and code implementation") and gives an explicit "Use when..." clause for when, matching the anchor-3 both-what-and-when bar; it is not 2 because the explicit trigger guidance is present.

"talk to Amelia" and "developer agent" are natural persona-invocation terms, but common work-trigger variations a user would say (e.g. "implement a story", "write code") are missing, keeping it at anchor 2 rather than 3.

The "Amelia"/"developer agent" trigger gives some distinctness, but the "code implementation" capability is broad and would overlap with other coding skills, so it is not the clearly-niched anchor 3.
