ryzhakar Cover one procedure per skill; never cover a second.
Write a skill where reading it does the work; never where the work happens without reading.
Never carry a version field in the frontmatter.
Take name from the procedure named above — two or three lowercase parts, hyphen-joined, naming what it does; never carry a fourth part.
Set the directory name to name; never let the two differ.
Write description as one sentence naming what the skill does, followed by the phrases and conditions a request matches; never merge the two into one sentence.
Put every phrase and condition a request matches in the description; never put one in the body — everything below the frontmatter.
Name each tag as an imperative verb phrase; never name a tag for its content alone.
Carry every instruction — one thing to do or refuse — in tag content; never carry one outside a tag.
Carry a tag's whole meaning in its content; never give a tag an attribute.
Inside a tag write prose and inline backticks; never write anything else.
Order the body as the procedure runs; never depart from that order.
Keep everything the skill needs inside it for one read; never point outside it to fetch, except by naming another skill.
Move what two skills both need into a third skill; never copy shared content into two skills.
Reference another skill by name; never by its path.
Write every instruction as a command; never as a suggestion.
Cap each sentence at one emphatic word — never, always, only, must; never carry two.
Count an emphatic word where it commands; never where backticks quote it.
Pair every positive instruction with the prohibition of that same instruction; never pair it with the prohibition of another concern.
State the instruction; never argue for it.
Name what the skill requires; never narrate a failure to meet it.
Hold one term per concept from its first use; never introduce a second term for a concept already named.
Define every term outside ordinary English, the file system, Markdown, YAML, and XML — and every common word carrying a narrow sense — in the sentence that first uses it; never leave one undefined.
Write anything a person will read in ordinary words; never in words that person would not use.
Keep every sentence that instructs or forbids; never keep another.
