Is the Create Diagram skill free?

Yes. The skill itself is free from Mertcikla/tld. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Create Diagram SkillProof Score?

9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.

How do I install Create Diagram?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Create Diagram with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Works with setup
Score: 9.2/10
Tested: Jul 31, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 4e1d449

Built the tld binary from source (Go 1.26; added a frontend/dist placeholder to satisfy a go:embed directive) since the CLI isn't bundled with the skill. Ran the skill's full workflow in a mock 3-tier repo: tld init, then the documented flat commands (add --ref/--kind/--parent, connect --from/--to/--label) via a .tld/diagram.sh execution log, then tld validate and tld plan — all succeeded, yielding 6 elements/6 connectors and surfacing an ARC102 missing-tech warning; tld tech suggest also worked. Every CLI shape in the body matched reality. Baseline for the same "diagram this system" task was a static Mermaid text block; the skill's output is a machine-validated, plannable, drill-down tld knowledge graph — clearly richer. Verdict is setup, not pass, because the tld binary must be installed separately (vendor curl|sh or a source build); copying the skill alone does nothing until tld is on PATH.

What Create Diagram does

Builds a navigable architecture model of a local codebase or described system using the tld CLI — elements, labeled connectors, and drill-down views — and records every command in a re-runnable .tld/diagram.sh execution log. Triggers when the user asks to diagram a repo, map system architecture, show component relationships, or create drill-down views. Requires the tld binary installed separately (it is not bundled with the skill).

How to install Create Diagram

git clone --depth 1 https://github.com/Mertcikla/tld.git /tmp/create-diagram-src
mkdir -p ~/.claude/skills
cp -R /tmp/create-diagram-src/skills/create-diagram ~/.claude/skills/create-diagram
# REQUIRES the `tld` binary on PATH (NOT bundled). Official installer (macOS/Linux):
#   curl -LsSf https://tldiagram.com/install.sh | sh
# Windows: powershell -ExecutionPolicy ByPass -c "irm https://tldiagram.com/install.ps1 | iex"
# Or build from source (needs Go 1.26+; go:embed needs a frontend/dist placeholder):
#   cd /tmp/create-diagram-src && mkdir -p frontend/dist && echo x > frontend/dist/index.html \
#     && go build -o /usr/local/bin/tld ./cmd/tld
# Plugin-marketplace alternative: repo is a Claude plugin (.claude-plugin/plugin.json + .agents/plugins/marketplace.json).

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Create Diagram

/create-diagram Build a navigable tld architecture model of a codebase via the tld CLI

It also activates on plain-language prompts like these:

Diagram the architecture of this repository
Map the component relationships in this system
Create a drill-down view of this service
