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.

What it costs to keep this loaded
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 | $0.00173 | $0.01307 |
| Opus 5 | $0.00086 | $0.00654 |
| Sonnet 5 | $0.00035 | $0.00261 |
| Haiku 4.5 | $0.00017 | $0.00131 |
Grade A, and why
staad-steel-design 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 11d 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.

STAAD.Pro Steel Design
Instructions
Design Workflow — 5 Steps
Step 1 — Create design brief
brief_ref = design.CreateDesignBrief(1067) # AISC 360-16
| Code | Standard |
|---|---|
| 1067 | AISC 360-16 |
| 1061 | AISC 360-10 |
| 1045 | AISC 360-05 |
| 1004 | BS 5950-1:2000 |
| 1220 | BS EN 1993-1-1 (Eurocode 3) |
| 1032 | IS 800 2007 LSD |
| 1149 | AS 4100 |
| 1182 | CSA S16-14 |
Step 2 — Assign design commands to members
design.AssignDesignCommand(brief_ref, 'CHECK CODE', '', beam_list)
# Returns True on success and raises on failure (execute_code reports any error)
| Command | Description |
|---|---|
| CHECK CODE | Verify member capacity against the code |
| SELECT | Optimize section (pick the lightest passing section) |
| TAKE OFF | Generate material take-off report |
Step 3 — Save to persist design commands
staad.SaveModel(True)
Step 4 — Run analysis + design
staad.SetSilentMode(True)
status = staad.AnalyzeEx(1, 0, 1) # silentMode=1, hiddenMode=0, waitTillComplete=1
staad.SetSilentMode(False)
# status == 2 means success
Step 5 — Read results
out = staad.Output
# Verify first
blk_count = out.GetSteelDesignParameterBlockCount() # must be > 0
# Per-member full results
r = out.GetMemberSteelDesignResults(bid)
# Returns: (codeName, status, ratio, allowable, critLC, critPos, clause, section, forces[FX,MY,MZ], klr)
# status: 'PASS' or 'FAIL'; ratio > 1.0 = failure
# Quick ratio only
ratio = out.GetMemberSteelDesignRatio(bid) # -999=not designed, -1=no analysis
# Model-wide extremes
max_r = out.GetMemberSteelDesignMaxFailureRatio()
min_r = out.GetMemberSteelDesignMinFailureRatio()
Design Parameters
Assign parameters before running analysis:
design.AssignDesignParameter(brief_ref, paramName, paramValue, member_ids)
# Returns True on success and raises on failure
| Parameter | Description | Example |
|---|---|---|
| BEAM | Member is a beam | "1" |
| FYLD | Yield strength | "250" (MPa) |
| FU | Ultimate strength | "400" (MPa) |
| KY | Effective length factor Y | "0.85" |
| KZ | Effective length factor Z | "1.0" |
| LY | Unbraced length Y | "3000" (mm) |
| LZ | Unbraced length Z | "3000" (mm) |
| CB | Bending coefficient | "1.0" |
| UNL | Unsupported length | "6000" (mm) |
| TRACK | Output detail level | "2" |
| DMAX | Maximum section depth | "600" (mm) |
| DMIN | Minimum section depth | "200" (mm) |
What ships with it
2 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.

staad-steel-design is a skill published in the GitHub repository BentleySystems/openstaad-mcp (42 stars, last pushed today), licensed MIT. It adds 173 tokens to every session and 1,307 once invoked, about $0.0009 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 2026-08-30.
