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.

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 | $0.00075 | $0.02691 |
| Opus 5 | $0.00037 | $0.01345 |
| Sonnet 5 | $0.00015 | $0.00538 |
| Haiku 4.5 | $0.00007 | $0.00269 |
Grade A, and why
do-storage-and-databases 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.
How it starts
The opening of the file, as written. The whole thing — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DigitalOcean Storage and Databases
When to use
- Choosing between object storage, block volumes, and a managed database engine.
- Sizing a Managed Database cluster and selecting a standby / high-availability plan.
- Hardening data-at-rest encryption, backups, and connection security.
- Auditing data egress, retention, snapshot lifecycle, and replication.
- Evaluating the tradeoff between a Managed Database and self-hosting on a Droplet.
Decision tree
| Need | Service |
|---|---|
| Object storage for blobs, backups, static assets, data lake | Spaces |
| Block storage attached to a Droplet or DOKS node | Volumes |
| ACID relational, OLTP, joins, JSONB | Managed PostgreSQL |
| MySQL-compatible relational | Managed MySQL |
| Document store, flexible schema, horizontal scale | Managed MongoDB |
| Sub-ms key-value cache, pub/sub, session store | Managed Redis / Valkey |
| Event streaming, message queue | Managed Kafka |
| Full-text search, log analysis | Managed OpenSearch |
| Self-hosted, heavy customization, license control | Droplet (Memory-Optimized or Storage-Optimized) + manual ops |
Spaces defaults
- Bucket policy: default to private. No public ACL unless the bucket exclusively serves public static assets. Use Spaces CDN + signed URLs for asset delivery rather than a public bucket.
- Encryption: Spaces encrypts data at rest with AES-256. There is no customer-managed key option as of 2026 — if key-level audit / revocation is required, encrypt objects client-side before upload.
- Versioning: enable on any bucket holding state, artifacts, or backups. Versioning is per-object and protects against accidental deletes.
- Lifecycle rules: expire non-current object versions after your retention window (e.g. 30 d for build artifacts, 90 d for application backups). Unmanaged non-current versions accumulate and bill silently.
- CORS: apply the narrowest CORS policy possible. Avoid
AllowedOrigins: ["*"]on a bucket that holds anything other than fully public assets. - Access control: use Spaces access keys scoped per application, not personal PAT credentials. Rotate keys on personnel change and on a 90-day schedule.
- CDN: enable Spaces CDN for any bucket serving end-user assets. CDN egress is cheaper than origin egress and reduces latency globally.
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.

do-storage-and-databases is a skill published in the GitHub repository jsgerman-oss/blackrim-nimbus-skills (8 stars, last pushed 26d ago), licensed MIT. It adds 75 tokens to every session and 2,691 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 2026-08-31.
