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: 2 findings, up to medium
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 →

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 | $0.00110 | $0.02656 |
| Opus 5 | $0.00055 | $0.01328 |
| Sonnet 5 | $0.00022 | $0.00531 |
| Haiku 4.5 | $0.00011 | $0.00266 |
Grade A, and why
aws-cli 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 — 162 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AWS CLI
Safety-first wrapper for AWS CLI v2 (aws). Every command is classified by risk tier BEFORE execution — full AWS control, w/ anything irreversible, breaking, or cost-incurring gated behind explicit AskUserQuestion confirmation. Blast radius on AWS is an entire company's infra: wrong account/region/flag can destroy data, break prod, or spend real money.
When to Use
- Run/inspect any AWS service: EC2, S3, IAM, Lambda, RDS, DynamoDB, CloudFormation, Route 53, ECS/EKS, CloudFront, SQS/SNS, CloudWatch, KMS, Secrets Manager, …
- Audit resources, costs, security posture; tail logs; query w/
--query(JMESPath) - Deploy/update infra, manage env config, rotate creds, debug failing calls
- Set up auth: profiles, IAM Identity Center (SSO), assume-role, MFA
Prerequisites (run once per session)
bash scripts/aws_preflight.sh [profile]
Reports version, profiles, region, and the active identity (sts get-caller-identity). NEVER run a write op w/o knowing which account+region you're pointed at. No profiles configured → guide setup via references/patterns.md (keys vs SSO).
Safety Model
| Tier | Action Required | Examples |
|---|---|---|
| Safe | Execute immediately | describe-*, get-*, list-*, s3 ls, sts get-caller-identity, logs tail, any --dry-run |
| Write | Inform user, then execute | create-*, put-*, tag-*, lambda update-function-code, s3 cp/sync |
| Destructive | AskUserQuestion BEFORE executing |
delete-*, terminate-instances, stop-*, run-instances (cost), modify-db-instance (downtime), change-resource-record-sets (live DNS), sg rules w/ 0.0.0.0/0 |
| Forbidden | Triple typed confirmation, NEVER auto-confirm | close-account, IAM user/role deletion, kms schedule-key-deletion, delete-stack, s3 rb --force, delete-db-instance --skip-final-snapshot, snapshot/backup deletion, disabling CloudTrail/GuardDuty, purchases (RIs, Savings Plans, domains) |
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-cli is a skill published in the GitHub repository georgekhananaev/claude-skills-vault (28 stars, last pushed 1mo ago), licensed MIT. It adds 110 tokens to every session and 2,656 once invoked, about $0.0006 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 2026-08-30.
