tree-review

tree-review is a skill for Claude Code from atman-33/workhub. It costs 138 tokens per session (1,033 once invoked), scanned A, original, MIT.

A review workflow for a logic tree: a diagram that breaks a problem into possible causes. It checks the tree for reasoning errors, then can group its smallest causes into a few larger issues with the user's input.

In plain words
What is it for?
Use it to inspect a pasted tree, file, or mind map, report flaws without changing it, and agree on a smaller set of major issues.
Why use it?
It helps separate real causes from symptoms, avoid unrelated branches, and expose places where the investigation stopped too early.

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

tree-review 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.

How it starts

The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

tree-review

The input is a tree that already exists: a problem at the root, causes below it. ladder up builds such a tree from nothing by asking; this skill takes the finished tree and does two jobs on it.

  • review — inspect the logic. You answer with findings.
  • group — boil the leaf causes down to a few major issues. You ask one question at a time and the user decides.

Take the mode from the argument. With none, run review first and offer group once the findings are dealt with. Read the tree in full before the first output: a file, a mind map note, or pasted text. Keep the user's wording for every node.

Review

Report findings only; do not edit the tree. Each finding names the node, quotes it, and says in one sentence what is wrong. Checks, in this order:

  1. Symptom mixed with cause. A node that restates its parent in other words is not a cause ("tasks pile up late" under "tasks increase"). Ask what produces it.
  2. Stopped at "not done". "We did not review X" is where a cause starts. Dig to why it was not done: no time, no owner, not seen as worth it.
  3. Mixed axes under one parent. Siblings should answer the same question. "Why is it slow now" and "why does it not get faster" are different questions and belong under different parents.
  4. Loops back to the root. A tree shows one direction, so a leaf that feeds the root hides a vicious circle. Name the loop explicitly: leaf → … → root → leaf.
  5. Fact or hypothesis. Mark each node as observed or inferred. List the inferred ones as hypotheses, with what would confirm them.

Close with a short list: findings by check, then the edits you suggest in words ("move X under Y", "split Z", "add the cause under W"). When the tree lives in a vault mind map, say the suggested edits can be handed to workhub:diagram-edit; this skill never writes the file itself.

Group

Start from the leaves, after the review findings are fixed or set aside. Ask one question per turn, building each from the user's last answer.

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.
