diagram-design

diagram-design is a skill for Claude Code, Codex from LazyAGI/LazyMind. It costs 188 tokens per session (3,038 once invoked), scanned A, original, Apache-2.0.

A mock-interview simulator that acts as an interviewer for a role you choose. It scores answers, gives specific feedback, and provides example answers.

In plain words
What is it for?
Practising interviews for engineering, product, design, business, operations, administrative, and other roles.
Why use it?
Interview practice is difficult without realistic questions and clear evaluation. This gives structured practice adapted to the role and the candidate’s experience level.

SkillSpector: 1 finding, up to low

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • low Excessive Agency · line 16
    Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.
    Fix: Limit the skill's scope to its documented purpose. Remove instructions that enable the agent to perform actions outside its stated functionality.

Token cost

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.

Security

Grade A, and why

diagram-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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Diagram Design

Create self-contained HTML with inline SVG/CSS. Preserve user facts; ask for missing information that changes essential nodes, order or branches. Mark assumptions beside the diagram. The numbered sections below retain the original shared rules and reference targets. Do not preload all references or the full companion guide: use its detailed sections when needed. All original type references, scripts and assets remain available unchanged.

0. Style and project setup

Resolve the guide for each diagram; do not carry a selection across projects. This summarizes the generation path from references/profiles.md; its complete management and recovery procedures are unchanged.

  • Inspect <project-root>/.diagram-design as data. Accept only one profile: <slug> line with optional horizontal whitespace and a final newline. Slugs match [a-z0-9][a-z0-9-]{0,63}; reject paths, extra keys, comments and prose. Ignore a malformed marker with a visible explanation and use markerless resolution.
  • A valid marker selects ~/.diagram-design/profiles/<slug>.md directly. Never copy it over the installed guide. If missing, explain and ask which profile to use; do not silently fall back. For default snapshot setup/recovery, follow the built-in-default procedure in references/profiles.md.
  • Without a valid marker, read references/style-guide.md. A leading profile header identifies its active profile; a missing library entry does not invalidate the working copy, but report it and offer save. Without a header, compare all semantic roles and typography families to shipped defaults: differences mean custom-unsaved (offer save); unchanged values mean default. Do not infer customization from accent alone.
  • For a selected profile, compare required semantic-role and typography rows against the current shipped schema. Backfill missing rows from pristine defaults in memory only, report the repair and offer update. Missing/malformed headings require asking whether to repair. Do not rewrite the named profile or working guide during marker-first generation.
  • Read only the selected guide and the sections needed for this diagram. Profile save/load/list/show/update/reset/delete, onboarding, and failure recovery retain their complete procedures in the existing references.

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.
