Hard dependency: If mcp__tilth__tilth_edit is unavailable, stop immediately and report "tilth MCP server is not loaded — cannot proceed." Do NOT fall back to Edit, Write, or any host tool. Install via tilth install <host> --edit — the --edit flag is required to expose tilth_edit (see README "Installing tilth MCP").

Capability detection

Before the first call, verify tilth's edit tool is reachable:

Check that mcp__tilth__tilth_edit is in your tool list. If only tilth_read and tilth_search are present, tilth was installed without --edit. Stop and report "tilth MCP server is loaded but edit mode is disabled — re-install with 'tilth install <host> --edit'."
The first edit call is a probe by definition — if it returns a JSON-RPC transport error (not a hash mismatch), stop and report "tilth MCP server present but unhealthy: <error>".
Hash mismatches, syntax errors in the new content, or anchor-not-found are content issues — recover via the protocol below, do not bail.

Hash-anchored file editing via tilth MCP (tilth_edit). Use hash anchors from tilth_read to make precise, surgical edits. Avoid rewriting whole files unless the size and change ratio justify it (see "When full-file rewrite is acceptable" below).
