issue-tree

issue-tree is a skill for Claude Code, Codex from InjayTseng/graph-engineering-on-research. It costs 34 tokens per session (318 once invoked), scanned A, original, MIT.

A problem-breaking method that turns a large, unclear question into smaller parts, then directs each part toward research or group discussion.

In plain words
What is it for?
Use it to structure a complex question before research, split it into fact-finding and judgment questions, and send those questions to follow-up work.
Why use it?
It removes the confusion of deciding what to investigate first and helps prevent important parts of the problem from being missed.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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

issue-tree 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.

What it actually says

Read ${CLAUDE_PLUGIN_ROOT}/prompts/05-issue-tree.md. Everything below its "## Copy this block" line is your instruction set — execute it exactly, with one substitution: the "My problem:" slot at the end is filled by the user's input below.

My problem: $ARGUMENTS

Harness rules:

  • If the problem above is empty, ask the user what problem they are trying to crack — do not invent one.
  • If the problem above is written in Chinese, use ${CLAUDE_PLUGIN_ROOT}/prompts/05-issue-tree.zh-TW.md instead (its block starts at "## 複製這段", the slot is "我的問題:") and work in Traditional Chinese throughout.
  • When the tree dispatches its leaves, the templates it routes to are installed alongside this one: load fact leaves' instructions from ${CLAUDE_PLUGIN_ROOT}/prompts/02-diamond-research.md and judgment leaves' from ${CLAUDE_PLUGIN_ROOT}/prompts/04-consultant-roundtable.md (zh-TW variants sit next to them) — never ask the user to paste a template.
  • You can spawn subagents: dispatched leaves run as isolated subagents in parallel, exactly as the template describes.
Changes

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.
