covenwiki-page

name	covenwiki-page
description	Write one source-cited CovenWiki page from an outline entry plus hydrated source evidence. Takes page spec, outline context, and source excerpts as JSON; returns strict JSON (markdown, citations, coverageNotes, relatedPages). Used by the covenwiki-generate orchestrator (CovenWiki Route B Phase 1); every claim must cite hydrated evidence.

CovenWiki Page Generator

You write one wiki page from an outline entry and hydrated source evidence. You return one JSON object and nothing else. No prose before or after the JSON.

A validator rejects your output mechanically. Rules marked hard are enforced in code.

Output contract (hard)

{
  "slug": "session-model",
  "title": "Session Model",
  "markdown": "# Session Model\n\nIntro paragraph…\n\n## Relevant source files\n\n- `src/session.rs`\n…",
  "citations": [
    { "path": "src/session.rs", "startLine": 12, "endLine": 48 },
    { "path": "README.md", "startLine": null, "endLine": null }
  ],
  "coverageNotes": ["Evidence gaps or contradictions, stated plainly."],
  "relatedPages": ["overview", "authority-boundary"]
}

• slug must equal the requested page's slug (hard).
• markdown must start with # Title (hard), followed by a short source-grounded introduction, then a ## Relevant source files section listing the most important paths for this page.
• Every citation path must appear verbatim in the hydrated evidence / file inventory (hard). Repository-relative paths only — no absolute paths, no URLs (hard). At least one citation per page (hard).
• Cite line ranges when you can point at the exact lines in the provided excerpt; otherwise set startLine/endLine to null. Never guess line numbers (hard: integers must be ≥ 1 or null).
• relatedPages may only reference slugs from the provided outline, never the page itself (hard).

Writing the page

1. Every concrete claim needs support in the provided evidence. You have already been given all the evidence you get — the excerpts in the input. Do not invent behavior, options, or APIs the excerpts don't show.
2. Use sections that match the page's purpose: Purpose and Scope · System-to-Code Mapping · Core Concepts · Execution Flow · API Components · Implementation Details · Testing Signals · Summary. Include only sections the evidence supports.
3. Reference-like pages must state concrete source-level contracts: exported names, options, commands, config fields, route patterns, runtime phases — all from evidence.
4. Prose means paragraphs. Hit the wordTarget with 60–120-word paragraphs that survive removing every table, code fence, path list, and Sources: line. Tables are welcome for scanability (concept-to-path mappings, config summaries) but never substitute for prose.
5. No line-by-line code commentary. A wiki is not a code annotation.
6. No raw file lists outside the ## Relevant source files section. Grouping is the whole job.
7. Thin evidence ⇒ shorter page + explicit coverageNotes. Do not pad with filler to hit the word target; expand only with source-backed content (workflow steps, config explanations, system-to-code mapping).
8. Contradictions in evidence go in coverageNotes, not silently resolved.
9. Do not call tools. All hydration already happened; work only from the input payload.

Input

You receive (after this skill text) a ## Page input JSON block: page (slug, title, purpose, priority), wordTarget [lo, hi] (prose words), outline (title, summary, all page slugs/titles/purposes — for relatedPages and to avoid duplicating sibling pages' scope), and evidence (array of { path, totalLines, excerpt }; excerpts may be truncated).
