Tools observed via MCP handshake

geml_list — List every addressable block in a GEML document — its address, kind and heading text — in one call, with no paging. Call this FIRST: what it returns is what eve
geml_find — Search block CONTENT in the document; each hit is one `<name>\t<address>` row. geml_list says what a document contains, this says which block holds the words —
geml_get — Read ONE block from a GEML document instead of the whole file: only that block comes back, typically a few percent of the document. Pass the `address` geml_list
geml_check — Validate a GEML document without changing it: returns every diagnostic with a stable `code`, a severity and a line, and an empty list means the document is vali
geml_to — Convert a WHOLE document and get the result back as text — the read half of the CLI's `geml <file> --to <fmt>`. `to: "geml"` on a Markdown file is the importer,
geml_set — Replace ONE block and leave every other byte untouched — prefer this to rewriting a file. For content that does not exist yet use geml_add; to remove a block, g
geml_add — Insert new content — one or more blocks, or prose — at the end of the document (`position: append`) or before/after the block named by `anchor`. Use this for co
geml_delete — Remove one or more blocks, each named by an id or any address geml_list prints; a filter (`=== type`, `{key=value}`) removes every block it matches. Each block
geml_rename — Rename a block id AND every reference to it in the same document, in one id-boundary-safe write. Use this rather than geml_set or a text search-and-replace, whi
