Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00040 | $0.10355 |
| Opus 5 | $0.00020 | $0.05178 |
| Sonnet 5 | $0.00008 | $0.02071 |
| Haiku 4.5 | $0.00004 | $0.01035 |
Grade A, and why
bim-scripting 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 12d 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.
This is a copy
100% identical to bim-scripting — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

BIM Scripting
Comprehensive reference for automating Building Information Modeling workflows through scripting, API access, and interoperability platforms. This skill covers the full spectrum of BIM automation --- from visual programming with Dynamo through deep Revit API scripting, pyRevit extension development, IFC/openBIM data exchange, model checking, automated documentation, and cross-platform interoperability via Speckle, BHoM, and Rhino.Inside.Revit.
1. BIM Automation Philosophy
Why Script BIM
BIM models are databases disguised as 3D geometry. Every wall, door, room, and duct segment carries structured data --- type, dimensions, material, cost code, fire rating, acoustic class, phase, workset, design option. Manual manipulation of that data does not scale. A 200-unit residential project may contain 40,000+ elements, each with 30--80 parameters. Changing a naming convention, verifying parameter completeness, or exporting coordinated drawing sets by hand is not just slow --- it is error-prone and unrepeatable.
Scripting BIM means treating the model as a programmable data source:
- Read element properties at scale (audit, validate, report).
- Write parameter values in batch (standards enforcement, data enrichment).
- Create elements procedurally (repetitive layouts, adaptive placement).
- Transform geometry computationally (facade panelization, structural optimization).
- Export deliverables automatically (sheets to PDF, models to IFC, data to dashboards).
Manual vs. Automated BIM Workflows
| Workflow | Manual Approach | Automated Approach | Time Savings |
|---|---|---|---|
| Parameter QA | Open each element, check value | Script scans all elements, flags violations | 95% |
| Sheet creation | Place views, adjust crops, add tags one by one | Script generates sheets from template rules | 90% |
| Clash detection | Visual inspection in section views | Navisworks / script-based interference check | 85% |
| Export to IFC | File > Export > IFC, configure, repeat per model | Batch script exports all linked models with preset mappings | 80% |
| Room finish schedule | Manual schedule, manual formatting | API-generated schedule with conditional formatting | 75% |
| Design option comparison | Duplicate views, switch options, compare | Script generates comparison report with metrics | 90% |
| Naming convention enforcement | Manual review of browser tree | FilteredElementCollector + regex validation | 98% |
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
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.

bim-scripting is a skill published in the GitHub repository marcinfinitesimal533/Claude-skills-for-Computational-Designers (2 stars, last pushed 2d ago), licensed MIT. It adds 40 tokens to every session and 10,355 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to bim-scripting, differing in 0 lines, and is treated as a copy.
