mindmap-mcts

mindmap-mcts is a skill for Codex from cheshireyang/mindmap-mcts-skill. It costs 78 tokens per session (2,023 once invoked), scanned A, original, MIT.

A visible reasoning-tree workflow that uses a lightweight search method called Monte Carlo Tree Search to explore possible solutions. The reasoning tree records evidence, alternatives, tests, and conclusions for complex coding tasks.

In plain words
What is it for?
Use it to investigate difficult bugs, compare designs, test competing hypotheses, or create a mind map of a Codex or Claude Code task.
Why use it?
It helps organize debugging or design work when several explanations or approaches are plausible. It makes trial-and-error and trade-offs easier to follow.

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

mindmap-mcts 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 9d ago.

The scan reads SKILL.md. This mod also ships 8 executable files (scripts/mindmap_mcts/__init__.py, scripts/mindmap_mcts/cli.py, scripts/mindmap_mcts/engine.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 193 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MindMap-MCTS

Use this skill to keep complex work on a visible, evidence-backed reasoning tree. The bundled CLI owns the JSON truth source, UCB selection, backpropagation, markdown rendering, static HTML rendering, and interactive Markmap HTML rendering; the agent owns expansion, real probes, and judgment.

Command Prefix

Choose the command form that matches the current shell. First set the skill directory for the host that loaded this skill.

Codex on Unix shells:

export MINDMAP_MCTS_SKILL_DIR="${CODEX_HOME:-$HOME/.codex}/skills/mindmap-mcts"

Claude Code on Unix shells:

export MINDMAP_MCTS_SKILL_DIR="${CLAUDE_HOME:-$HOME/.claude}/skills/mindmap-mcts"

Default install locations are $HOME/.codex/skills/mindmap-mcts for Codex and $HOME/.claude/skills/mindmap-mcts for Claude Code.

Linux, macOS, WSL, or Git Bash:

"$MINDMAP_MCTS_SKILL_DIR/scripts/mindmap" --help

Cross-platform Python launcher:

python "$MINDMAP_MCTS_SKILL_DIR/scripts/mindmap.py" --help

Windows PowerShell:

# Claude Code:
$env:MINDMAP_MCTS_SKILL_DIR = "$env:USERPROFILE\.claude\skills\mindmap-mcts"

# Codex:
# $env:MINDMAP_MCTS_SKILL_DIR = "$env:USERPROFILE\.codex\skills\mindmap-mcts"

& "$env:MINDMAP_MCTS_SKILL_DIR\scripts\mindmap.ps1" --help

If PowerShell execution policy blocks .ps1 scripts, run the Python module directly after setting PYTHONPATH:

$env:PYTHONPATH = "$env:MINDMAP_MCTS_SKILL_DIR\scripts;$env:PYTHONPATH"
$env:PYTHONIOENCODING = "utf-8"
[Console]::OutputEncoding = [System.Text.Encoding]::UTF8
python -m mindmap_mcts.cli --help

For repeated commands in one shell session, define:

alias mindmap='"$MINDMAP_MCTS_SKILL_DIR/scripts/mindmap"'

If aliases are not preserved by the current shell call, use the explicit launcher form for the current shell.

On Windows, set UTF-8 output before rendering or showing trees that contain Chinese text:

$env:PYTHONIOENCODING = "utf-8"
[Console]::OutputEncoding = [System.Text.Encoding]::UTF8

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.
