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 | $0.00082 | $0.02967 |
| Opus 5 | $0.00041 | $0.01484 |
| Sonnet 5 | $0.00016 | $0.00593 |
| Haiku 4.5 | $0.00008 | $0.00297 |
Grade A, and why
alibaba-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.

Alibaba Storage and Databases
When to use
- Choosing between relational, document, key-value, wide-column, analytics, and object storage.
- Designing OSS lifecycle rules, cross-region replication, or bucket-level access policy.
- Sizing an RDS or PolarDB cluster, picking a failover strategy, or enabling PITR.
- Selecting between PolarDB and RDS for a new relational workload.
- Hardening encryption, backups, and replication on any data store.
- Auditing data egress, retention, and residency requirements for China-region compliance.
Decision tree
| Need | Service |
|---|---|
| Object storage for blobs, backups, data lake, static assets | OSS |
| Block storage attached to an ECS instance | EBS (cloud disk) |
| Shared POSIX filesystem across compute | Apsara File Storage NAS (standard or extreme) |
| High-throughput parallel filesystem (HPC) | Apsara File Storage CPFS |
| ACID relational OLTP, well-known engine | RDS (MySQL / Postgres / SQL Server / MariaDB) |
| Cloud-native relational, fast failover, scale-out reads, up to 100 TB | PolarDB (MySQL / Postgres / Oracle-compat) |
| Single-digit-ms document or key-value | ApsaraDB for MongoDB |
| Sub-ms cache or pub/sub, sorted sets | ApsaraDB for Redis |
| Wide-column, time series, full-text, hybrid | Lindorm (HBase-compatible + extensions) |
| Petabyte MPP analytics, SQL at scale | AnalyticDB for MySQL or AnalyticDB for PostgreSQL |
OSS defaults
- Storage class: Standard for hot data; Infrequent Access (IA) after 30 d; Archive after 90 d; Cold Archive after 365 d. Set lifecycle rules from day one.
- Encryption: SSE-OSS (server-managed) minimum; SSE-KMS with a CMK for any data subject to access-audit, compliance, or residency requirements. SSE-C (customer-provided key) only when you control key material in-process.
- Block Public Access (BPA): on at the bucket level by default. Never expose a bucket publicly to serve content — use CDN + private origin with a signed URL or RAM STS token.
- Versioning: on for any bucket holding state, source artifacts, or backups.
- Cross-region replication: for DR or data-residency purposes; note China ↔ International replication is not available — both buckets must be in the same account type (China or International).
- Object Lock (WORM): on for compliance / ransomware-recovery buckets.
- Transfer Acceleration: available for OSS uploads/downloads from external networks; billed separately.
- Notifications:
PutObject/DeleteObjectevents → EventBridge or MNS for downstream pipelines. - Access logs: enable OSS access logging to a separate log bucket; set lifecycle on the log bucket.
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.

alibaba-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 82 tokens to every session and 2,967 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.
