Mermaid Diagrams
Preserve editable Mermaid source. Render a static asset only when the consumer requires one.
Route by Structure
| Type | Best for | Reference | Example |
| --- | --- | --- | --- |
| Flowchart | processes and decisions | references/flowchart.md | assets/examples/flowchart/basic.mmd |
| Sequence | ordered system interactions | references/sequence.md | assets/examples/sequence/basic.mmd |
| Class | object models | references/class.md | assets/examples/class/basic.mmd |
| State | lifecycle transitions | references/state.md | assets/examples/state/basic.mmd |
| ER | data entities and relationships | references/er.md | assets/examples/er/basic.mmd |
| Other | Gantt, pie, git, journey, timeline, mindmap, requirement, C4 | references/other-types.md | assets/examples/other/gantt-basic.mmd |
Load only the matching reference.
Workflow
- Identify the relationships, sequence, or states the diagram must communicate and choose the matching type.
- Write one focused
.mmdsource with descriptive labels and simple alphanumeric or underscore IDs. Split a graph that becomes unreadable. - Validate with the consumer's Mermaid renderer when known. Otherwise, use Mermaid CLI when available:
mmdc -i diagram.mmd -o /tmp/diagram-check.svg
- If a slide or document needs a static asset, render the requested SVG with an appropriate theme, background, and dimensions, then inspect it in the target artifact.
- Return or preserve the source, any requested rendered artifact, validation performed, and renderer/version compatibility caveats.
Quote labels containing punctuation. Prefer high contrast for slides. Diagram creation does not authorize a Git commit or publication.

narumiruna/scoring-agent-skills
development
VerifiedTrustedCommunity
Score or compare one or more agent skills across trigger clarity, workflow actionability, safety boundaries, verification rigor, incremental knowledge value, and leanness. Use only when the user explicitly asks for ratings, numerical quality scores, rubric-based scorecards, or scored comparisons; use creating-agent-skills for unscored reviews or revisions.

narumiruna/improving-codebase-architecture
development
VerifiedTrustedCommunity
Assess or improve an existing codebase's architecture when the user asks about module boundaries, coupling, scattered ownership, testability, change locality, deep modules, seams, or behavior-preserving structural refactoring. Use for cross-module design rather than ordinary diff review or a confirmed edge-case bug fix.

narumiruna/auditing-code-security
development
VerifiedTrustedCommunity
Perform read-only security audits, vulnerability assessments, or threat-focused reviews of diffs, pull requests, code paths, or explicitly scoped repositories when security is the primary objective or acceptance criterion. Use reviewing-code for ordinary review with baseline security coverage and hardening-code-paths for fixing confirmed findings.

narumiruna/running-panel-review-loops
development
VerifiedTrustedCommunity
Run iterative multi-reviewer panels over a code diff, verify their findings, apply explicitly authorized fixes, and re-review the updated change until it passes or reaches a stopping condition. Use when the user asks for a panel loop, multi-model code-review consensus, or a review-fix-re-review cycle.
