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 | $0.00054 | $0.00537 |
| Opus 5 | $0.00027 | $0.00269 |
| Sonnet 5 | $0.00011 | $0.00107 |
| Haiku 4.5 | $0.00005 | $0.00054 |
Grade A, and why
sysml-modeling-standard 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 10d 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.

SysML Modeling Standard
Apply this skill as the default entry point for SysML work in this workspace.
When To Use
Use this skill when the user asks to:
- create a SysML model
- modify an existing SysML model
- review SysML model quality
- define requirements, behaviors, structures, interfaces, states, parameters, or traceability
- perform Sysbuilder-based modeling in this workspace
If the task will use Sysbuilder software, Sysbuilder APIs, Sysbuilder MCP tools, or Sysbuilder automation scripts, read Sysbuilder建模要求.md before any such action and treat it as a hard execution constraint.
Mandatory Workflow
- Read references/SysML建模规范.md for the workspace modeling rules.
- If the task will use Sysbuilder automation scripts, also read ../../quickref/sysbuilder_python_api.md.
- Clarify the current modeling goal:
- requirement analysis
- behavior analysis
- architecture design
- interface/parameter/verification traceability
- Build the minimum sufficient model for the task. Do not add diagrams that do not answer an engineering question.
- Keep naming consistent, unique, and searchable. Prefer Chinese names in this workspace unless the source standard explicitly requires otherwise.
- Follow the standard package layering, element usage, diagram-selection rules, and API compatibility rules.
- Build the core traceability chain where applicable:
- source -> requirement -> behavior -> structure -> verification
- Before finishing, check naming consistency, relation semantics, interface consistency, and modeling completeness against the requested scope.
What To Output
When reporting results for a modeling task, provide:
- which modeling goal was addressed
- which standard rules were applied
- which key traceability links were created or checked
- any unsupported diagram/tool limitations and how they were handled
- any violations found and the corrective action taken
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.

sysml-modeling-standard is a skill published in the GitHub repository Suzhou-Tongyuan/sysbuilder-mcp-server (4 stars, last pushed 3mo ago), licensed MIT. It adds 54 tokens to every session and 537 once invoked, about $0.0003 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.
