Printing The Semantics Tree

Q: What is a Claude Code skill and how does the Printing The Semantics Tree skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Printing The Semantics Tree is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category.

type:debug

Use this skill to diagnose "no node matched", "found N nodes", and "useUnmergedTree" failures by dumping the actual semantics tree with `printToLog(tag, maxDepth)` and `printToString(maxDepth)`. Covers the output grammar (`Node #<id> at (l, t, r, b)px, Tag: '...'`, alphabetically sorted config, `Actions = [...]`, `[FlagKey]` for `Unit`-valued semantics, `MergeDescendants`, `ClearAndSetSemantics`), the framework hint that suggests `useUnmergedTree = true` when matches are found only in the unmerged tree, and `fetchSemanticsNode` / `fetchSemanticsNodes` for custom matchers. Use when the developer reports "tag not found", "multiple nodes matched", "merged tree vs unmerged tree", "test fails with assertion error and a long error message", or wants to debug a finder without adding `Thread.sleep`.

About this skill (catalog notes)

Printing The Semantics Tree includes explicit scope boundaries (an explicit 'when not to use' or 'out of scope' section); a dedicated installation section; 13 code blocks for direct copy-paste. The SKILL.md runs to about 1,406 words, in the catalog's typical mid-range.

How Printing The Semantics Tree fits the catalog

Printing The Semantics Tree sits in the General category under the orchestration-frameworks sub-topic in the ClaudSkills catalog. There are 10 related skills indexed alongside it; comparing a few before installing usually reveals which fits your workflow best.

These notes are auto-generated from features detected in the SKILL.md file and from this catalog's structure — they aren't part of the source repository.

From the source SKILL.md

onNodeWithTag failures are structural — the tag is wrong, the matcher is on the merged tree but the tag is on a leaf, or the node is genuinely not composed yet. None of those are timing problems, so Thread.sleep does nothing. This skill teaches the agent to diagnose finder failures by dumping the semantics tree with printToLog / printToString and reading the framework's built-in "found in the unmerged tree" hint.

What this skill does

Printing The Semantics Tree is a community-contributed Claude Code skill in the orchestration-frameworks sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/printing-the-semantics-tree/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the developer reports "tag not found", "multiple nodes matched", "merged tree vs unmerged tree", "test fails with assertion error and a long error message", or wants to debug a finder without adding `Thread.sleep`.

Who uses this skill

The Printing The Semantics Tree Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 85,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
