doctor

doctor is a command for coding agents from 404-not-found/mindlink. It costs 0 tokens per session (631 once invoked), scanned A, original, MIT.

A terminal health check for a MindLink project, which stores an AI assistant’s project memory in a .brain folder. It checks that the memory files, settings, and agent instructions exist and are valid.

In plain words
What is it for?
Use it after installing or importing MindLink, or when memory is not being loaded correctly. It checks the project folder, JSON settings, memory files, session history, agent files, and Claude Code hook.
Why use it?
It helps find broken or missing setup files when the assistant is not working as expected. It returns a failure status when a critical problem is found.

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

doctor 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 4d 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.

Synopsis

mindlink doctor

Description

Runs a series of checks on your project's MindLink setup and reports any problems. Exits with code 1 if any critical issues are found, 0 if everything is healthy (warnings are allowed).


What Gets Checked

Check What it looks for
.brain/ Exists in the current directory
config.json Present and valid JSON
MEMORY.md Core section has content; warns if getting too long
SESSION.md Has content and shows when it was last updated
LOG.md Session count, last session date, how far back history goes
Agent files Each configured agent's instruction file exists
Claude hook .claude/settings.json hook is present and valid

Output

  ◉ MindLink Doctor
  /Users/yuanhong/my-app

  ✓  .brain/ found
  ✓  config.json valid
  ✓  MEMORY.md Core has content
  ✓  SESSION.md — updated 2 hours ago
  ✓  LOG.md — 12 sessions logged (last: Apr 10, 2026, going back to: Jan 5, 2026)
  ✓  CLAUDE.md — Claude Code
  ✓  CURSOR.md — Cursor
  ✓  .claude/settings.json — UserPromptSubmit hook active
  ·  .brain/ is committed to git (shared team memory)

  All good. Your AI has a healthy brain.

Warning example

  !  MEMORY.md Core is getting long
     Consider asking your AI to consolidate — Core is read on every session start.

  1 warning, no critical issues. Your AI will still work.

Failure example

  ✗  MEMORY.md missing
     Run mindlink init to recreate it.

  1 problem found — fix the issues above and re-run mindlink doctor.

Exit Codes

Code Meaning
0 Healthy (warnings allowed)
1 One or more critical problems found

When to Run

  • After mindlink import — verify the import landed correctly
  • When your AI seems confused or isn't reading context — check the agent files
  • On a new machine after cloning — make sure instruction files are in place
  • Periodically to catch drift before it becomes a problem

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.
