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.

SkillSpector: 2 findings, up to medium
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 →
- medium Agent Snooping · line 11 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.
- medium Rogue Agent · line 21 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00056 | $0.01661 |
| Opus 5 | $0.00028 | $0.00830 |
| Sonnet 5 | $0.00011 | $0.00332 |
| Haiku 4.5 | $0.00006 | $0.00166 |
Grade A, and why
design-critique 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 11d 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 — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Evaluate the design quality of a feature or component. Report-only — this skill documents issues but does not fix them.
Preparation
Read ~/.claude/skills/minoan-frontend-design/SKILL.md for aesthetic principles and anti-pattern guidance. If no .design-context.md exists in the project root, ask the user about audience and intended feel before proceeding — context determines whether a design choice is right or wrong.
Resolve Target and Load Ignore List
-
Resolve the primary artifact. Map the user's phrasing to a concrete file path: "the homepage" →
src/pages/index.tsx, "the settings modal" →src/components/Settings.tsx. File paths are stable across runs; dev-server ports drift. -
Read the ignore list at
.design-critique/ignore.mdif it exists. Each non-empty, non-comment line is something the user has marked as "do not re-raise" (deferred tradeoffs, designer-intended deviations, accepted false positives). When a finding matches a line (case-insensitive substring), drop it silently — do not mention it in the report.
Step 1: LLM Design Review
Read the relevant source files (HTML, CSS, JS/TS) and visually inspect if browser automation is available. If using browser automation, create a new tab — never reuse an existing tab, to prevent state interference between assessments.
Evaluate as a design director:
AI Slop Detection: Does this look like every other AI-generated interface? Check against the rejection guidelines in the minoan skill. Look for: AI color palette, gradient text, glassmorphism, hero metric layouts, identical card grids, generic fonts (including second-tier defaults like Fraunces, Instrument Sans, Outfit), side-tab accent borders. The test: if someone said "AI made this," would they believe immediately?
Holistic Design Review: Visual hierarchy (eye flow, primary action clarity), composition (balance, whitespace, rhythm), typography (hierarchy, readability, font choices), color (purposeful use, cohesion, accessibility), states & edge cases (empty, loading, error, success).
What ships with it
1 file 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.
- 11d ago First seen · 124 lines · 56 tokens per session scan A 1cd74e577878
design-critique is a skill published in the GitHub repository tdimino/claude-code-minoan (41 stars, last pushed today), licensed MIT. It adds 56 tokens to every session and 1,661 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 2026-08-30.
