Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00078 | $0.02023 |
| Opus 5 | $0.00039 | $0.01012 |
| Sonnet 5 | $0.00016 | $0.00405 |
| Haiku 4.5 | $0.00008 | $0.00202 |
Grade A, and why
mindmap-mcts scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 193 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MindMap-MCTS
Use this skill to keep complex work on a visible, evidence-backed reasoning tree. The bundled CLI owns the JSON truth source, UCB selection, backpropagation, markdown rendering, static HTML rendering, and interactive Markmap HTML rendering; the agent owns expansion, real probes, and judgment.
Command Prefix
Choose the command form that matches the current shell. First set the skill directory for the host that loaded this skill.
Codex on Unix shells:
export MINDMAP_MCTS_SKILL_DIR="${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.

mindmap-mcts is a skill published in the GitHub repository cheshireyang/mindmap-mcts-skill (110 stars, last pushed 2mo ago), licensed MIT. It adds 78 tokens to every session and 2,023 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
