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 | $0.00091 | $0.01561 |
| Opus 5 | $0.00046 | $0.00781 |
| Sonnet 5 | $0.00018 | $0.00312 |
| Haiku 4.5 | $0.00009 | $0.00156 |
Grade A, and why
revit-bim 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Revit BIM Design
Create, modify, and analyze building designs in Autodesk Revit 2024/2025/2026/2027 through natural language. All building professionals — architects, structural engineers, MEP engineers, and interior designers — describe what they want, and elements are created automatically via 48 MCP tools connected to the live Revit model.
Core Principles
- Think like a building professional. Follow real construction logic: structure before enclosure, enclosure before finishes.
- All tools accept millimeters (mm). The server converts to Revit internal feet automatically.
- Query before creating. Check available family types and current model state before placing elements.
- Batch where possible. Create tools accept arrays — group similar elements into a single call.
Building Design Sequence
Follow this order when designing a building from scratch:
- Levels — Define floor-to-floor heights (
create_level) - Grids — Establish the column grid layout (
create_grid) - Columns — Place structural columns at grid intersections (
place_family) - Beams — Connect columns with structural beams (
create_structural_framing) - Exterior walls — Building envelope along the perimeter (
create_line_based_element) - Interior walls — Room partitions (
create_line_based_element) - Openings — Doors and windows placed on walls (
place_family) - Floors — Floor slabs at each level (
create_surface_based_element) - Roof — Top enclosure (
create_surface_based_element) - Documentation — Dimensions, tags, sheets, schedules (
create_dimensions,tag_walls,create_sheet,create_schedule)

What ships with it
7 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.

revit-bim is a skill published in the GitHub repository Demolinator/revit-mcp-plugin (6 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 91 tokens to every session and 1,561 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
