# Claude Platform on AWS
**Anthropic-operated** access to the Claude Developer Platform through AWS infrastructure — SigV4 authentication, AWS IAM access control, and AWS Marketplace billing. Because Anthropic operates it, **the API surface matches first-party with same-day parity**: Managed Agents, server-side tools, batches, Files, and every feature in this skill work the same way. Model IDs are the bare first-party strings (`{{OPUS_ID}}`, `{{SONNET_ID}}`) — **no provider prefix**.
> **Not the same as Amazon Bedrock.** Bedrock is partner-operated (AWS runs the service; release schedules vary, feature subset, `anthropic.`-prefixed model IDs). Claude Platform on AWS and Bedrock coexist; pick by whether you need AWS-native IAM/billing with full Anthropic API parity (this page) vs. Bedrock's own ecosystem.
---
## Client & install
| Language | Install | Client |
|---|---|---|
| Python | `pip install -U "anthropic[aws]"` | `from anthropic import AnthropicAWS``AnthropicAWS()` |
| TypeScript | `npm install @anthropic-ai/aws-sdk` | `import AnthropicAws from "@anthropic-ai/aws-sdk"``new AnthropicAws()` |
| Go | `go get github.com/anthropics/anthropic-sdk-go` | `import anthropicaws "github.com/anthropics/anthropic-sdk-go/aws"``anthropicaws.NewClient(ctx, anthropicaws.ClientConfig{})` |
| C# | `dotnet add package Anthropic.Aws` | `new AnthropicAwsClient()` |
| Java | See SDK repo in `shared/live-sources.md` | See SDK repo in `shared/live-sources.md` |
| Ruby | `gem install anthropic aws-sdk-core` | See SDK repo in `shared/live-sources.md` |
| PHP | `composer require anthropic-ai/sdk aws/aws-sdk-php` | See SDK repo in `shared/live-sources.md` |
After construction, **use the client exactly as you would `Anthropic()`**`client.messages.create(...)`, `client.beta.sessions.*`, etc., with bare model IDs.
```python
from anthropic import AnthropicAWS
client = AnthropicAWS() # region + workspace_id from env; see below
client.messages.create(
model="{{OPUS_ID}}",
max_tokens=1024,
messages=[{"role": "user", "content": "Hello"}],
)
```
---
## Required configuration
Two values must be available (constructor args or environment) — **there is no default fallback** for either:
| Value | Env var | Notes |
|---|---|---|
| AWS region | `AWS_REGION` | Required. Unlike `AnthropicBedrock`, there is no `us-east-1` fallback. |
| Workspace ID | `ANTHROPIC_AWS_WORKSPACE_ID` | Required. Routes requests to your Claude workspace. |
Endpoint pattern: `https://aws-external-anthropic.{region}.api.aws/v1/...`. Requests are SigV4-signed with service name `aws-external-anthropic`.
## Authentication
The client resolves AWS credentials via the standard precedence chain: explicit constructor args → environment (`AWS_ACCESS_KEY_ID`/`AWS_SECRET_ACCESS_KEY`/`AWS_SESSION_TOKEN`) → shared profile → assumed role / instance metadata.
**Short-term API keys** are also supported for cases where SigV4 isn't practical (e.g., browser, simple scripts). Mint one with the per-language token-generator package; pass it as `api_key` on the client. Lifetime is the **lesser of** the requested duration, the underlying credential's expiry, and **12 hours**. For package names and IAM details, WebFetch the Claude Platform on AWS page in `shared/live-sources.md`.
---
## What to tell users
- Treat it as first-party: every section of this skill applies unchanged. Do **not** apply Bedrock's feature-availability mask.
- Model IDs are bare (`{{OPUS_ID}}`). Do **not** add an `anthropic.` prefix.
- A missing region or `workspace_id` throws at client-construction time (no request is sent). A **403** means the request reached the server — check for a **wrong** `workspace_id` or a missing IAM action on the principal. See the IAM actions reference in `shared/live-sources.md`.

**Managed Agents** is a third surface: server-managed stateful agents with Anthropic-hosted tool execution. You create a persisted, versioned Agent config (`POST /v1/agents`), then start Sessions that reference it. Each session provisions a container as the agent's workspace — bash, file ops, and code execution run there; the agent loop itself runs on Anthropic's orchestration layer and acts on the container via tools. The session streams events; you send messages and tool results back.

- `reason`: one short sentence on why you picked that delay.

The task tools haven't been used recently. If you're working on tasks that would benefit from tracking progress, consider using ${TASK_CREATE_TOOL_NAME} to add new tasks and ${TASK_UPDATE_TOOL_NAME} to update task status (set to in_progress when starting, completed when done). Also consider cleaning up the task list if it has become stale. Only use these if relevant to the current work. This is just a gentle reminder - ignore if not applicable. Make sure that you NEVER mention this reminder to the user

@ -44,6 +44,21 @@ PowerShell Syntax Notes:
- Environment variables: read with `$env:NAME`, set with `$env:NAME = "value"` (NOT `Set-Variable` or bash `export`)
- Call native exe with spaces in path via call operator: `& "C:\Program Files\App\app.exe" arg1 arg2`
Unix commands that DO NOT exist in PowerShell — use the equivalent instead:
- head / tail → `Get-Content file -TotalCount N` / `-Tail N`; piped: `| Select-Object -First N` / `-Last N`
- which → `(Get-Command name).Source`
- touch → `if (-not (Test-Path path)) { New-Item -ItemType File path }` (NEVER use `New-Item -Force` on a file — it truncates existing content)
- wc -l → `(Get-Content file | Measure-Object -Line).Lines`
- mkdir -p → `New-Item -ItemType Directory -Force path` (`-p` is not a PowerShell flag)
- rm -rf → `Remove-Item -Recurse -Force path`
- ln -s → `New-Item -ItemType SymbolicLink -Path link -Target target`
- chmod / chown → not applicable on Windows; use `icacls` only if ACL changes are required
- 2>/dev/null → `2>$null` (but stderr is captured for you — usually unnecessary)
- VAR=x cmd → `$env:VAR = 'x'; cmd` (PowerShell has no inline env-var prefix)
- Bash control flow (`if [ -f x ]`, `for x in *`, backtick ``cmd`` substitution) is a parser error — use `if (Test-Path x)`, `foreach ($x in ...)`, `$(cmd)`
Exit-code note: `-ErrorAction SilentlyContinue` suppresses error OUTPUT but the cmdlet failure still causes this tool to report exit 1. To make a cmdlet failure truly non-fatal, promote it to terminating and swallow it: `try { Cmdlet ... -ErrorAction Stop } catch {}` (without `-ErrorAction Stop`, non-terminating errors skip the `catch` and still exit 1).
Interactive and blocking commands (will hang — this tool runs with -NonInteractive):
- NEVER use `Read-Host`, `Get-Credential`, `Out-GridView`, `$Host.UI.PromptForChoice`, or `pause`
- Destructive cmdlets (`Remove-Item`, `Stop-Process`, `Clear-Content`, etc.) may prompt for confirmation. Add `-Confirm:$false` when you intend the action to proceed. Use `-Force` for read-only/hidden items.
