Write and prune documents an agent consumes: a SKILL.md, an AGENTS.md or CLAUDE.md, a rules file, a reference file reached by a pointer. Use when authoring or revising a skill, editing standing agent instructions or recording a decision as a rule agents will follow, or diagnosing why a document fires unreliably or gets skimmed.
Write or revise technical documentation a human engineer reads: architecture and reference docs, runbooks, decision records, write-ups and reports. Use when drafting or editing such a document, or when a technical text reads as dense, vague, or hard to scan.
Write or revise outgoing communication for a non-engineering reader: an email, a Slack or chat message, an announcement, a status update, a proposal, a post, a letter, customer-facing copy. Use when drafting such text, when a draft sounds AI-generated, generic, or stiff, or when asked to scrub text for signs of AI writing.
