What it does
Structural Logic is an agent skill from lukapiskorec/craftbot. Use for every building regardless of material, when settling the bearing stack before geometry, when checking that every element has a load path to ground and a bearing at every seat, when checking lateral stability per direction, when sizing concrete, steel or masonry members without an engineer, and when running the independent structural review. The Designer and the Builder load it always; timber-framing is loaded on top of it only when timber is one of the materials.
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: CraftBot is an architect AI agent. It interprets design briefs, grounds its thinking in domain knowledge through ingesting documents, images and other references, and outputs…
When your agent uses it
- Every building regardless of material
- Settling the bearing stack before geometry
- Checking that every element has a load path to ground and a bearing at every seat
- Checking lateral stability per direction
Example prompts
- “/structural-logic”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Vertical load path continuous to ground for every element family, written as sentences.
- Lateral stability per direction: shear elements named, diaphragms named, spans stated, and every shear element reaching the diaphragm it…
- Bearing at every seat with a length, and continuity at every discontinuity (openings, cores, level changes, cantilevers).
- Foundations: undersides relative to grade, stepped on slopes, retaining walls with bases and top restraint.
- Sizes plausible for their spans by the catalogue and the rules above; anything outside the manuals named.
- Details that fail by gravity, sliding, moisture or racking (posts on slabs get plinths; hollow undercrofts get access; roofs drain…
What it can do on your machine
Read from SKILL.md and the folder at commit 2c9715b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Structural Logic loads about 1.8k tokens when it runs. Until then it costs about 123 tokens; SKILL.md has 1,179 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,179 words (~1,844 tokens).
“A building is a set of load paths, not a set of shapes. For every element, name what load it carries and into which element it delivers it, and place it accordingly. This skill holds the part of that habit…”

Structural Logic is an agent skill from lukapiskorec/craftbot. Use for every building regardless of material, when settling the bearing stack before geometry, when checking that every element has a load path to ground and a bearing at every seat, when checking lateral stability per direction, when sizing concrete, steel or masonry members without an engineer, and when running the independent structural review.
When should I use Structural Logic?
Structural Logic fits situations like: every building regardless of material; settling the bearing stack before geometry; checking that every element has a load path to ground and a bearing at every seat; checking lateral stability per direction.
How do I install Structural Logic in Claude Code?
Run `npx skills add lukapiskorec/craftbot --skill structural-logic -a claude-code`. Or copy the skill folder (skills/structural-logic in lukapiskorec/craftbot) into .claude/skills/structural-logic in your project. Claude Code loads it when a task matches its description.
How do I install Structural Logic in Codex?
Run `npx skills add lukapiskorec/craftbot --skill structural-logic -a codex`. Or copy the skill folder (skills/structural-logic in lukapiskorec/craftbot) into .agents/skills/structural-logic in your project. Codex loads it when a task matches its description.
Can I use Structural Logic in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add lukapiskorec/craftbot --skill structural-logic -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/structural-logic, .gemini/skills/structural-logic, .github/skills/structural-logic and .opencode/skills/structural-logic in your project.
What does Structural Logic need to run?
SKILL.md names no scripts, command-line tools or credentials: Structural Logic is instructions for the agent only.
Does Structural Logic access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Structural Logic safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Structural Logic use?
Structural Logic has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Structural Logic use?
About 1.8k tokens (SKILL.md is roughly 7.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Structural Logic?
Skills that share tags, products or a category with Structural Logic: Frontend Slides (zarazhangrui/frontend-slides, 30k stars), Algorithmic Art with p5.js (anthropics/skills, 180k stars), Canvas Design (anthropics/skills, 180k stars) and Impeccable (bestofjs/bestofjs, 3.1k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
