think-tree

think-tree is a skill for Claude Code, Codex from aaronsb/claude-code-config. It costs 38 tokens per session (283 once invoked), scanned B, original, MIT.

A reasoning method that explores several possible solutions as branches, compares them, removes weaker options, and selects one.

In plain words
What is it for?
Use it to compare designs, evaluate alternatives, and make a reasoned choice. It requires following a defined sequence of stages and managing a temporary thinking session.
Why use it?
It helps when a problem has multiple plausible approaches and the best choice is not immediately clear.

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 B, and why

think-tree scanned grade B with 1 finding 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 3d 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.

What it actually says

Tree of Thoughts

Start Session

Before beginning, register this think session:

# Check for active session
if [[ -f /tmp/.claude-think-session ]]; then cat /tmp/.claude-think-session; fi

If another session is active, ask the user to finish or abandon it first. Otherwise:

echo "tree-of-thoughts" > /tmp/.claude-think-session

Work Through Stages

Read the strategy definition and follow its stages in order:

cat ~/.claude/hooks/ways/meta/think/strategies/tree-of-thoughts.md

Work through each numbered stage sequentially. Do not skip stages. Present your work for each stage before moving to the next.

Complete Session

After the final stage (Solution Synthesis), clean up so the think way can fire again:

rm -f /tmp/.claude-think-session /tmp/.claude-way-meta-think-*"${CLAUDE_SESSION_ID:+-$CLAUDE_SESSION_ID}" 2>/dev/null

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.
