What it does
Sc Mermaid is an agent skill from kylesnowschwartz/SimpleClaude. Generate mermaid diagrams — flowcharts for architecture, sequence diagrams for interactions. This skill SHOULD be used when the user asks to "create a diagram", "draw an architecture diagram", "sequence diagram", "flowchart", "visualize the system", or "generate mermaid".
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Diagrams. It works with Mermaid. The repository describes itself as: Practical minimalism for AI assisted programming with Claude Code.
When your agent uses it
- Asks to create a diagram
- Draw an architecture diagram
- Sequence diagram
- Visualize the system
Example prompts
- “create a diagram”
- “draw an architecture diagram”
- “sequence diagram”
- “/sc-mermaid”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Scope identification: Determine which components, services, and relationships to include
- Architecture analysis: Read relevant files and understand data/control flow
- Validation: Cross-reference findings against codebase to ensure accuracy
What it can do on your machine
Read from SKILL.md and the folder at commit abb293b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Sc Mermaid loads about 1.2k tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 379 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 379 words (~1,203 tokens).
“Generate mermaid diagrams for architecture visualization and interaction flows.”
