🤖 Filed by Claude Code on Kai's behalf.

Inspiration: anthropics/skills - public reference skills including the production xlsx / pdf / pptx / docx skills that power Claude's document features. They lean heavily on Python helpers, not pure prompts.

Joins against: the "Bias toward Python helpers, not pure-prompt skills" rule in coilyco-ai/AGENTS.md, the cognition stack (log-sessions, session-rollup, reading-list, pulse).

Anthropic's open skills are the strongest public example of the helpers-over-prompts pattern. Kai independently arrived at the same rule and runs an actual production stack on it. A blog post that walks the pattern: prompt is for narrative, Python is for data, with a side-by-side comparison against Anthropic's xlsx skill and Kai's log-sessions. Lands a third spot in the existing blog series alongside coily-as-boundary and gauntlet, and is the only one that's specifically about how to author with Claude rather than how to operate Claude.
