A guide to using the AWS command-line tools to manage Amazon Web Services accounts and resources. AWS is a cloud platform; the guide covers identity, single sign-on, storage, containers, and monitoring.

Use it to inspect and manage AWS accounts, IAM permissions, S3 storage, ECS container services, and CloudWatch monitoring through the command line.

It reduces the risk of running a command in the wrong account or region. It also provides a safer process for checking identity, refreshing sign-in sessions, and limiting read queries.

aws — Skill for Claude Code and Codex by fmind/dot

Install

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.

Any agent

npx skills add fmind/dot --skill aws

Token cost

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	$0.00017	$0.00919
Opus 5.5	$0.00007	$0.00368
Sonnet 5.5	$0.00003	$0.00184
Haiku 4.5	$0.00002	$0.00092

Security

Grade A, and why

aws 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 today.

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 — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Amazon Web Services CLI

Use aws and aws-sso-util for AWS account, IAM, S3, ECS, and CloudWatch operations.

Workflow

Resolve identity and profile context: inspect the active AWS profile, SSO session, and caller identity; never assume role or run commands under ambiguous profiles.
```
aws sts get-caller-identity --profile <profile> --output json --no-cli-pager
aws configure list-profiles
```
Authenticate via SSO: when credentials expire, refresh the session using AWS IAM Identity Center (SSO); avoid long-lived access keys. When Identity Center is unavailable, aws login exchanges a console sign-in for short-lived credentials; add --remote on a host without a local browser.
```
aws sso login --profile <profile>
# Or using aws-sso-util:
aws-sso-util login --profile <profile>
# Without Identity Center:
aws login --profile <profile>
```
Pin every consequential call: pass --profile <name> and --region <region> explicitly so environment variables or shell defaults cannot redirect operations to the wrong account or region.
Start read-only with bounded queries: use --query (JMESPath) and --max-items to constrain results; describe resources, IAM policies, and CloudWatch metrics before changing anything.
```
aws s3 ls --profile <profile> --region <region> --no-cli-pager
aws ecs list-clusters --profile <profile> --region <region> --max-items 20 --output json --no-cli-pager
```
Authorize mutations: resource creation, security group changes, policy updates, and deletions require user authorization; reuse existing authority rather than asking again.

Gotchas

Refresh expired SSO tokens: SSO tokens expire after their configured duration; refresh via aws sso login rather than falling back to static API keys.
--query runs client-side: select needed fields and pair with supported server-side filters and --max-items; --page-size only changes request size, not total results. Preserve NextToken in projections, report capped results as partial, and resume deliberately when completeness is required. Use --no-cli-pager for agent calls; avoid debug output around credentials.
Failures are findings: report authorization (AccessDeniedException) or missing role errors directly; do not attempt permission escalation or modify IAM policies without authorization.

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 is a skill published in the GitHub repository fmind/dot (11 stars, last pushed yesterday), licensed MIT. It adds 17 tokens to every session and 919 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-17.
