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.

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 | $0.00000 | $0.00500 |
| Opus 5 | $0.00000 | $0.00250 |
| Sonnet 5 | $0.00000 | $0.00100 |
| Haiku 4.5 | $0.00000 | $0.00050 |
Grade A, and why
aws-dynamodb 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 9d 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 — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AWS DynamoDB API Skill
Overview
Amazon DynamoDB is a fully managed NoSQL database. This skill covers the AWS SDK v3 with a strong emphasis on the DocumentClient.
Installation
npm install @aws-sdk/client-dynamodb @aws-sdk/lib-dynamodb
pip install boto3
Authentication
Uses standard AWS IAM authentication.
Core Concepts
- Partition Key (PK): Determines data distribution.
- Sort Key (SK): Enables range queries and sorting.
- GSI: Global Secondary Index for alternative access patterns.
Common Workflows
- Instantiate
DynamoDBClient. - Wrap it with
DynamoDBDocumentClient.from(client). - Execute a
QueryCommandorPutCommand.
Error Handling
Handle ProvisionedThroughputExceededException via exponential backoff (SDK v3 does this automatically up to a limit). Handle ConditionalCheckFailedException for optimistic locking.
Security
Use IAM conditions to restrict access to specific Partition Keys (e.g., tenant isolation) if acting on behalf of users.
Rate Limits
Limits are based on Provisioned Capacity (WCUs/RCUs) or On-Demand mode throughput.
Best Practices
Use Single Table Design to minimize network trips. Avoid Scan operations at all costs; always Query using well-defined indexes.
Troubleshooting
If a Query returns unexpected results, ensure you are specifying the IndexName if querying a GSI, and that the GSI has finished populating.

Why use this skill
Use this when your agent works with aws-dynamodb — structured patterns beat pasted docs and prevent common hallucinations.
AI pitfalls
- Inventing column names or schema fields
- Using deprecated driver methods or wrong connection strings
- Omitting connection pooling or transaction boundaries
Production checklist
- Migrations version-controlled and applied via CI
- Connection limits and pooling configured
- Backups and restore procedure documented
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

aws-dynamodb is a skill published in the GitHub repository ashish7802/awesome-api-skills (13 stars, last pushed 8d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 500 tokens. 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.
