At a glance

Guides Blender Python that generates construction geometry from derived parametric expressions instead of hand-typed coordinates, so changes propagate and overlaps stay checkable.

  • Writing Blender Python that generates a roof frame or wall system
  • SKILL.md covers Overview, Single source of truth, Cutting and joining and Dimension chains and counts, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Revising a building script that relies on typed-in coordinates

What it does

This skill is a set of working rules for Blender Python scripts that model construction elements such as roofs, walls, rafters and cladding. The central idea is a single source of truth: levels and positions come from parametric functions, so changing a parameter such as roof pitch regenerates a consistent frame instead of breaking typed numbers, and the geometry stays checkable with a numeric overlap test.

The rules cover sharing one surface function among every member that meets it, one parametrized constructor per member family, generating a feature list once and passing it everywhere, addressing openings by slot index, and deriving secondary members from the members actually placed. For cutting and joining it advises building members long and clipping them with half-spaces, and splitting members at discontinuities rather than branching on boundary predicates. If a collision check script exists in the repo's tools it should be used to verify intersections, otherwise intersections are checked in the model file.

When your agent uses it

  • Writing Blender Python that generates a roof frame or wall system
  • Revising a building script that relies on typed-in coordinates
  • Making sure parametric members meet cleanly without overlapping
  • Adding windows or doors to a gridded wall without breaking panels

Example prompts

  • “Rewrite my Blender roof script so every purlin and rafter comes from one roof-plane function.”
  • “Add a door opening to the wall generator using slot indices instead of coordinates.”
  • “Check the rafter model for intersections and fix members that collide.”

Requirements

  • Blender with Python scripting

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

Procedural Geometry for Blender Scripts loads about 1.4k tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 851 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

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 851 words (~1,431 tokens).

“The model hangs off a small set of derived expressions, not a table of constants. Everything below serves two goals: a parameter change propagates instead of breaking hand-entered numbers, and the geometry stays checkable by a numeric overlap test. If…”
