simscape-write-ssc
simscape-write-ssc is a skill in matlab/simulink-agentic-toolkit, last changed 16 Sept 2026. It can name web addresses and include files we can't read.
Use when writing or editing Simscape Language (.ssc) source files — components, domains, or functions. Triggers include: model a physical component in .ssc; write physical equations for a Simscape block; add or modify physics or parameterization options in a Simscape component; build a composite component. Also use for validating .ssc syntax, fixing Simscape Language errors, or converting governing equations into working Simscape component code. Do NOT use for configuring or connecting existing Simscape blocks in a Simulink model — that is model building, not language authoring.

Pattern check
Pattern check: 1 item to review · commit ef5d5f8 · 29 Oct 2026
We checked every text file in this skill, at commit ef5d5f8 on 29 Oct 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

Format check
Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.
Agent Skills specPasses
The open format from agentskills.io, held to what the strictest agents enforce, so one folder loads everywhere.
- Note
Reference files over 100 lines with no table of contents at the top: references/foundation/gas.md (156 lines), references/foundation/isothermal-liquid.md (102 lines), references/foundation/moist-air.md (209 lines), references/foundation/thermal-liquid.md (183 lines) and references/foundation/two-phase-fluid.md (287 lines). B5
Fix: Add a short list of the sections at the top of each.
- Note
Claude CodePasses
Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.

Reference files over 100 lines with no table of contents at the top: references/foundation/gas.md (156 lines), references/foundation/isothermal-liquid.md (102 lines), references/foundation/moist-air.md (209 lines), references/foundation/thermal-liquid.md (183 lines) and references/foundation/two-phase-fluid.md (287 lines). B5
Fix: Add a short list of the sections at the top of each.
- Note
Claude apps & API uploadPasses
Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.
- Note
The description is 585 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4
Fix: If the claude.ai upload refuses it, trim the description to 200 characters.
