Proseweaving plugin
Proseweaving is an Agent Plugins v1 plugin for prose that agents write to people: the register a reader should meet, the evidence discipline behind every claim in that prose, the post-draft edit passes that enforce style as actions rather than preferences, and the adversarial pass that reads a finished draft as its recipient before it ships. Claude Code uses a native manifest projected from the same canonical plugin identity.
Writing standards are portable equipment here, not personal taste: a consumer without the author's own global instructions still receives the mechanics. Personal voice composes on top through consumer-global instructions and never lives in this plugin.
Proseweaving owns generic human-facing prose mechanics, including selection of register for a publication, document, or conversation. Its general writing skill applies to authored PR and Issue prose as well as other human-facing text; conversational openings and reply etiquette live in a conditional reference. Surface owners keep their content and format contracts: Mergecraft owns reviewer-facing pull-request text and review-specific framing, and Tricritical owns review findings and their structural output contract. Compose those contracts with Proseweaving while preserving their retained-text and publication boundaries; projections do not cross plugin boundaries.
Claude Code also discovers the native proseweaver agent alias. It is a thin
forwarder to the public skill, so the skill remains the portable policy owner.
Codex and other Agent Plugins clients consume the standard skill surface and do
not load this Claude-native agent definition.

Adapter boundary
Root plugin.json and skills/ are the canonical Agent Plugins plugin root;
.claude-plugin/plugin.json is a projection of the same identity. Skill-to-skill
edges use literal public identities linked to sibling SKILL.md files. Codex
adapters and each skill's agents/openai.yaml use $proseweaving:<skill> targets.
The root agents/proseweaver.md file is a Claude-native adapter and is not a
portable Agent Plugins component. The roster projection above is generated from
topology.json by the content-lock writer.
Validation
python -m unittest tests.test_validate_proseweaving exercises the focused
contract suite. python3 scripts/validate_proseweaving.py . validates the plugin from the
repository root: manifest identity and projection, topology, skill contracts,
the generated roster projection, inventory, portability, and the semantic content lock.
--write-content-lock regenerates the roster projection and the lock after an
authored change. evals/delivery.json governs plugin delivery, while
skills/writing-for-people/evals/evals.json carries the skill behavior corpus.
The plugin declares no Task Witness provider yet; publication eligibility and
inclusion in a release slate is decided outside this plugin.
