Release v2.9.0 — writing-antipatterns + Neo4j LinkML generators · meaningfy-ws/skillery

Added

writing-antipatterns skill (meaningfy-core). The register/genre-conditional catalogue of
how writing fails: a genre map (Tutorial, How-to, Reference, Explanation, Decision, Decision
record, Contract/specification, Coaching dialogue), a short list of defects that apply regardless
of genre, and a single-sourced inversion matrix of genre-conditional antipatterns — a rhetorical
question is craft in an explainer and a defect in an ADR, and the catalogue names exactly where
each move flips. Per-genre reference files are pointer tables only, never restating an entry.
Tested Neo4j-targeting LinkML generators (tools/linkml_neo4j/). A Cypher-constraint
generator and a neomodel OGM generator, vendored as tested repo tooling — not a skill asset, per
skill-repo governance. Fixes real bugs in the generators' original form: relationship targets now
resolve correctly against abstract LinkML classes, existence constraints are emitted for required
multivalued scalar/enum properties, and an opt-in slot annotation lowers to a generated Neo4j
index. project-setup projects both generators via a new --neo4j scaffold flag.
docs/skill-inventory.md, generated. A skill-by-skill map (purpose, category, dependencies,
and a related-skills graph), generated with a freshness test guarding drift.

tools/opencode_gen no longer mirrors __pycache__/.pyc/.pyo into .opencode/.
CI dependency gap: click, linkml, neomodel, jinja2 were missing from
requirements-dev.txt — passed locally only because a dev venv already had them.
OpenSpec validator quirk: its SHALL/MUST check only scans a requirement's first physical line.
Archived the linkml-neo4j-generators change (completed but never archived); corrected a stale
spec delta that still named the generators' pre-relocation path.
