migrate

migrate is a skill for Claude Code, Codex from cynthiajones34/GBrain. It costs 24 tokens per session (1,225 once invoked), scanned A, a copy of migrate, MIT.

A data-import workflow for moving notes and structured files into GBrain. It supports tools such as Obsidian, Notion, Logseq, Roam, Markdown, CSV, and JSON.

In plain words
What is it for?
Use it to import note collections, wikis, tables, exports, and structured data, then verify page counts, links, and search coverage.
Why use it?
It preserves the original source while converting links, block references, and fields into GBrain’s format. A small test import and health check help catch problems before a bulk migration.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

migrate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to migrate — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Migrate Skill

Universal migration from any wiki, note tool, or brain system into GBrain.

Contract

  • Source data is never modified or deleted; migration is additive only.
  • Every migrated page is verified round-trip: written to gbrain, read back, spot-checked.
  • Cross-references from the source system (wikilinks, block refs, tags) are converted to gbrain equivalents.
  • Migration is tested on a sample (5-10 files) before bulk execution.
  • Post-migration health check confirms page count, link integrity, and embedding coverage.

Supported Sources

Source Format Strategy
Obsidian Markdown + [[wikilinks]] Direct import, convert wikilinks to gbrain links
Notion Exported markdown or CSV Parse Notion's export structure
Logseq Markdown with ((block refs)) Convert block refs to page links
Plain markdown Any .md directory Import directory into gbrain directly
CSV Tabular data Map columns to frontmatter fields
JSON Structured data Map keys to page fields
Roam JSON export Convert block structure to pages

Phases

  1. Assess the source. What format? How many files? What structure?
  2. Plan the mapping. How do source fields map to gbrain fields (type, title, tags, compiled_truth, timeline)?
  3. Test with a sample. Import 5-10 files, verify by reading them back from gbrain and exporting.
  4. Bulk import. Import the full directory into gbrain.
  5. Verify. Check gbrain health and statistics, spot-check pages.
  6. Build links. Extract cross-references from content and create typed links in gbrain.

Obsidian Migration

  1. Import the vault directory into gbrain (Obsidian vaults are markdown directories)

  2. Wire the graph with native wikilink support (v0.12.1+):

    gbrain extract links --source db --dry-run | head -20    # preview
    gbrain extract links --source db                         # commit
    

    extract links natively parses [[relative/path]] and [[relative/path|Display Text]] alongside standard [text](page.md) markdown syntax. Ancestor-search resolution handles wiki KBs where authors omit one or more leading ../ prefixes. The .md suffix is inferred automatically for wikilinks.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
