M3E: Skill for Claude Code

.claude/skills/m3e-mapify-bridge/SKILL.md

m3e-mapify-bridge is a skill for Claude Code from akaghef/M3E. It costs 109 tokens per session (623 once invoked), scanned A, original, MIT.

A guide for moving structured content between M3E and Mapify, then checking whether the structure survived. Mapify is used as an intermediate teaching or testing tool, while M3E remains the source of truth.

In plain words
What is it for?
Use it to export an M3E subtree, send it to Mapify, retrieve an XMind export, convert it back, and compare the tree with the original.
Why use it?
It avoids relying on undocumented Mapify interfaces and catches missing, extra, or reordered nodes before a conversion is called successful.

This is akaghef/M3E's own configuration. It tells Claude Code how to work on M3E itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything M3E configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 tools/rapid_mapify_oracle/scripts/xmind_content_to_appstate.py <content.json> --out <retrieved_appstate.json>.

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

m3e-mapify-bridge 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.

How it starts

The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

M3E Mapify Bridge

Use Mapify as a teacher/probe layer, not as canonical M3E storage.

Current known-good route:

M3E subtree / MF-H / Markdown
-> Mapify input
-> Mapify UI export as XMind
-> recover XMind content.json
-> convert to AppState-lite / structural tree
-> strict compare against the original structure

Do not treat Mapify private/internal API readback as open unless it has been verified in the current session. The previously reliable path is XMind export.

Required Workflow

  1. Resolve the M3E target precisely: workspace, map, scope, node.
  2. Export only the intended subtree as MF-H or Markdown headings.
  3. Send that structure to Mapify. If using MCP, keep the exact outbound text.
  4. Retrieve through Mapify XMind export when possible.
  5. Convert XMind content.json with:
python3 tools/rapid_mapify_oracle/scripts/xmind_content_to_appstate.py <content.json> --out <retrieved_appstate.json>
  1. Compare original vs retrieved structure before claiming success.

Success means all are true:

  • same node count
  • same max depth
  • same ordered parent-child paths
  • no missing or extra node paths
  • no missing or extra tree edges

If artifacts are on Windows-only paths, classify them as peer evidence unless the files are actually synced to this host.

Safety

  • Do not extract or print Mapify cookies, OAuth tokens, API keys, or browser session material.
  • Do not make Mapify the source of truth.
  • Do not write retrieved data into an M3E map until the strict comparison result is known and the user asked for writeback.
  • Do not create throwaway M3E maps for verification unless explicitly asked.
  • Use existing import/export code and tools/rapid_mapify_oracle/ before inventing new parsers.

References

  • Detailed roundtrip procedure: references/roundtrip.md
  • Existing Mapify policy: tools/rapid_mapify_oracle/docs/mapify_io_policy.md
  • XMind converter: tools/rapid_mapify_oracle/scripts/xmind_content_to_appstate.py

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.
