Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 13 findings, up to high
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 →
- high Privilege Escalation · line 264 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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 | $0.00039 | $0.02027 |
| Opus 5 | $0.00019 | $0.01014 |
| Sonnet 5 | $0.00008 | $0.00405 |
| Haiku 4.5 | $0.00004 | $0.00203 |
Grade B, and why
convex-backend scanned grade B with 1 finding 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 5d 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.
Sends data to an external URLmediumData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

Convex Backend
Use Convex to build type-safe backend logic with realtime data sync.
When to Use This Skill
Use this skill when:
- Building real-time collaborative apps (chat, dashboards, multiplayer)
- Need a backend with zero infrastructure management
- Want type-safe server functions with automatic caching
- Building AI apps that need reactive data (agent status, streaming results)
- Prototyping quickly with a managed database + functions
Prerequisites
- Node.js 18+
- npm or pnpm
- Convex account (free tier: 1M function calls/month)
Quick Start
# Initialize Convex in an existing project
npm install convex
npx convex dev # Start local development (syncs with cloud)
# In a new project
npm create convex@latest
Schema Definition
// convex/schema.ts
import { defineSchema, defineTable } from "convex/server";
import { v } from "convex/values";
export default defineSchema({
users: defineTable({
name: v.string(),
email: v.string(),
role: v.union(v.literal("admin"), v.literal("member")),
avatarUrl: v.optional(v.string()),
createdAt: v.number(),
})
.index("by_email", ["email"])
.index("by_role", ["role"]),
messages: defineTable({
userId: v.id("users"),
channelId: v.id("channels"),
body: v.string(),
attachments: v.optional(v.array(v.string())),
createdAt: v.number(),
})
.index("by_channel", ["channelId", "createdAt"])
.index("by_user", ["userId"]),
channels: defineTable({
name: v.string(),
description: v.optional(v.string()),
isPrivate: v.boolean(),
}),
});
Queries (Real-Time Reads)
// convex/messages.ts
import { query } from "./_generated/server";
import { v } from "convex/values";
export const listByChannel = query({
args: {
channelId: v.id("channels"),
limit: v.optional(v.number()),
},
handler: async (ctx, args) => {
const messages = await ctx.db
.query("messages")
.withIndex("by_channel", (q) => q.eq("channelId", args.channelId))
.order("desc")
.take(args.limit ?? 50);
// Resolve user data for each message
return Promise.all(
messages.map(async (msg) => {
const user = await ctx.db.get(msg.userId);
return { ...msg, user: user ? { name: user.name, avatarUrl: user.avatarUrl } : null };
})
);
},
});
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.
- 5d ago First seen · 322 lines · 39 tokens per session scan B 88e496a813f6
convex-backend is a skill published in the GitHub repository BagelHole/DevOps-Security-Agent-Skills (1,067 stars, last pushed 3mo ago), licensed MIT. It adds 39 tokens to every session and 2,027 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (sends data to an external url). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
