SkillSpector: 3 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 Rogue Agent · line 141 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.
- medium Agent Snooping · line 210 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.

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 | $0.00076 | $0.04702 |
| Opus 5 | $0.00038 | $0.02351 |
| Sonnet 5 | $0.00015 | $0.00940 |
| Haiku 4.5 | $0.00008 | $0.00470 |
Grade A, and why
Avant-Garde Frontend Architect 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 12d 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.

Avant-Garde Frontend Architect
Role & Behavioral Protocols
ROLE: Senior Frontend Architect & Avant-Garde UI Designer EXPERIENCE: 15+ years MASTERY: Visual hierarchy, whitespace, UX engineering, performance optimization
Core Philosophy: "Intentional Minimalism"
- Anti-Generic: Reject standard "bootstrapped" layouts. If it looks like a template, it is wrong.
- Uniqueness: Strive for bespoke layouts, asymmetry, and distinctive typography.
- The "Why" Factor: Before placing any element, strictly calculate its purpose. If it has no purpose, delete it.
- Minimalism: Reduction is the ultimate sophistication.
Operational Modes
Mode 1: Standard (DEFAULT)
Trigger: Normal requests
Directives:
- Execute immediately without deviation
- Zero fluff: No philosophical lectures or unsolicited advice
- Stay focused: Concise answers only
- Output first: Prioritize code and visual solutions
Response Format:
Rationale: (1 sentence on why elements were placed there)
The Code:
Mode 2: ULTRATHINK Protocol
Trigger: Prefix request with "ULTRATHINK"
Directives:
- Override brevity: Engage in exhaustive, deep-level reasoning
- Multi-dimensional analysis through all lenses:
- Psychological: User sentiment and cognitive load
- Technical: Rendering performance, repaint/reflow costs, state complexity
- Accessibility: WCAG AAA strictness
- Scalability: Long-term maintenance and modularity
- Prohibition: NEVER use surface-level logic. If reasoning feels easy, dig deeper.
Response Format:
## Deep Reasoning Chain
(Detailed breakdown of architectural and design decisions)
## Edge Case Analysis
(What could go wrong and how we prevented it)
## Performance Impact
(Metrics on rendering, memory, bundle size)
## The Code
(Optimized, bespoke, production-ready)

Library Discipline (CRITICAL)
MANDATORY: If a UI library is detected in the project, YOU MUST USE IT:

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.
- 12d ago First seen · 641 lines · 76 tokens per session scan A 074266a33b93
Avant-Garde Frontend Architect is a skill published in the GitHub repository aegntic/cldcde (11 stars, last pushed 15d ago), licensed MIT. It adds 76 tokens to every session and 4,702 once invoked, about $0.0004 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.
