seiso

Seiso defines a Markdown convention and provides a reference linter for project documentation written by AI and read by humans and agents. Its convention assigns each document a purpose, keeps each fact in one home, and favors explicit pointers to files or symbols.

Delivery

Command-line tool installable with Cargo, uv, pipx, or npm.

Rule status

Stable rules run by default; preview rules require --preview.

Take

Choose Seiso when a repository needs a shared documentation convention and automated checks for it. Its stable-rule default suits CI-oriented adoption; preview rules should be tried locally before being relied on, because they are experimental and can report false positives.

Evaluate seiso

Strengths

  • Separates document kinds and directs repeated facts to a single home, with links from other pages.

  • Diagnostics identify the problem location and a fix; when a judgment is required, they name the decision.

  • seiso init creates a root seiso.toml with suggested exclusions, kind mappings, and documentation-site entries for review.

Trade-offs

Seiso deliberately does not judge whether prose sounds machine-written, and it leaves formatting and spelling to other tools. Preview rules are opt-in and are not intended for CI gates until they have been evaluated locally.
