Merge Summary Into Concept Or Entity Page
wiki.summaryMergeAdds a cited section to an existing concept or entity page, creating the page with canonical frontmatter if missing. Includes citation source, quote, and updates frontmatter.
Instructions
Add a cited section to an EXISTING Concepts/ or Entities/ page, or create the page with canonical frontmatter if targetPath does not exist. The new section is rendered under heading (default: Update YYYY-MM-DD); citationSource adds a [[wiki-link]] to the source and pushes it onto the page's sources: frontmatter list, and citationQuote renders as a blockquote under the citation. On existing pages, updated: frontmatter is bumped to today. Use this when filing a follow-up onto a known page; use wiki.ingest instead when bringing in a NEW source (which auto-creates Sources/<slug>.md). When creating a new entity page, entityKind is required.
Operates on the session-active vault (see vault.current — selectable via vault.select) unless an explicit vaultPath argument is passed, which always wins.
Examples:
Example 1 — Append a 'Notable Facts' section to an existing concept page, citing one source with a quote.:
{
"targetPath": "wiki/Concepts/circuit-breaker.md",
"heading": "Notable Facts",
"newSection": "Adopted by payment-service after the 2026-04-10 cascade incident.",
"citationSource": "wiki/Sources/postmortem-2026-04-10-payment-timeouts-cascade.md",
"citationQuote": "Timeouts in payment-service propagated to order-service within 14s."
}Example 2 — Create a new entity page for an organization on first reference.:
{
"targetPath": "wiki/Entities/anthropic.md",
"pageType": "entity",
"entityKind": "org",
"newSection": "AI safety lab; publisher of the Model Context Protocol.",
"summary": "AI safety company behind Claude and MCP."
