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: 16 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 Tool Misuse · line 111 Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

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 | $0.00029 | $0.02467 |
| Opus 5 | $0.00015 | $0.01234 |
| Sonnet 5 | $0.00006 | $0.00493 |
| Haiku 4.5 | $0.00003 | $0.00247 |
Grade A, and why
cloudflare-r2 scanned grade A 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 7d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Cloudflare R2
S3-compatible object storage with zero egress fees, built on Cloudflare's global network.
When to Use
- Storing user uploads, media files, backups, or static assets.
- Replacing AWS S3 to eliminate egress costs for read-heavy workloads.
- Serving files at the edge via Workers or public bucket access.
- Building multi-cloud storage that avoids vendor lock-in (S3 API compatible).
- Storing ML model artifacts, training data, or inference results.
Prerequisites
- Cloudflare account with R2 enabled (dashboard > R2 > subscribe).
- Wrangler CLI v3+ installed:
npm install -g wrangler. - Authenticated via
wrangler loginorCLOUDFLARE_API_TOKEN. - For S3 API access: R2 API token created under R2 > Manage R2 API Tokens.
Bucket Management with Wrangler
Create and List Buckets
# Create a new bucket
npx wrangler r2 bucket create app-assets
# Create a bucket in a specific region (hint for data locality)
npx wrangler r2 bucket create eu-uploads --location=eu
# List all buckets
npx wrangler r2 bucket list
# Delete an empty bucket
npx wrangler r2 bucket delete old-bucket
Object Operations
# Upload a single file
npx wrangler r2 object put app-assets/images/logo.png --file=./logo.png
# Upload with content type
npx wrangler r2 object put app-assets/data/report.json \
--file=./report.json \
--content-type="application/json"
# Download an object
npx wrangler r2 object get app-assets/images/logo.png --file=./downloaded-logo.png
# Delete an object
npx wrangler r2 object delete app-assets/images/old-logo.png
# Get object metadata
npx wrangler r2 object head app-assets/images/logo.png
S3-Compatible API Access
R2 supports the S3 API, so existing tools (AWS CLI, boto3, s3cmd) work out of the box.
Generate R2 API Tokens
- Go to R2 > Manage R2 API Tokens > Create API token.
- Select permissions: Object Read & Write, or Object Read only.
- Scope to specific buckets if possible.
- Save the Access Key ID and Secret Access Key.
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.

cloudflare-r2 is a skill published in the GitHub repository BagelHole/DevOps-Security-Agent-Skills (1,071 stars, last pushed 3mo ago), licensed MIT. It adds 29 tokens to every session and 2,467 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
