# strands-stigmer

The execution graph of AWS for [Strands](https://strandsagents.com) agents.

A single toolset that gives your agent verified AWS method contracts (required params, IAM permissions, pagination contracts, call-chain links, and known traps), a **least-privilege IAM policy generator** for multi-step workflows, and a **pre-flight authorization check** that asks AWS's own policy simulator whether an operation is allowed before it executes.

Backed by [Stigmer](https://stigmer.network), an open MCP knowledge network with 30,000+ contracts across 380 services.

## Install

```bash
pip install strands-stigmer
```

## Usage

```python
from strands import Agent
from strands_stigmer import stigmer_query, stigmer_policy, stigmer_authorize

agent = Agent(tools=[stigmer_query, stigmer_policy, stigmer_authorize])

# Generate a least-privilege IAM policy for a workflow
agent("Generate the least-privilege policy for an S3 multipart upload with KMS encryption")

# Pre-flight check: is s3:PutObject allowed for the current role?
agent("Before you call S3, check whether I'm authorized to put objects")
```

## Tools

`stigmer_policy(workflow="", operations="", description="")`
- Generate a least-privilege IAM policy. Pass one of:
  - `workflow` - a named workflow (see `stigmer_list_workflows`)
  - `operations` - explicit IAM actions or SDK symbols, comma-separated
  - `description` - describe the workflow in plain language
- Returns: paste-ready policy grouped by service, with confidence tier and any unresolved operations

`stigmer_authorize(operations="", workflow="", principal_arn="")`
- Pre-flight authorization check. Resolves the IAM actions an operation requires, then asks AWS's own policy simulator (`SimulatePrincipalPolicy`) whether the current role (or a given principal) allows them
- Returns `resolution` (exact|partial|unresolved) and `evaluation` (allowed|denied|unknown) as separate fields, plus `missing_permissions` and the simulator's documented caveats
- `evaluation` is populated only when the calling environment has AWS credentials; otherwise it is `unknown` with the reason

`stigmer_verify(workflow="", operations="", policy="")`
- Feed a generated policy back to AWS's own evaluator (`SimulateCustomPolicy`) and confirm it grants exactly the intended operations and nothing extra
- Returns `verified` (True|False|unknown), `grants_all`, and `grants_extra`
- `verified` is populated only when the calling environment has AWS credentials

`stigmer_list_workflows()`
- List the curated named workflows available for policy generation

`stigmer_query(query, library="")`
- Search verified method contracts: required params, IAM permissions, pagination contract, call-chain links, and known traps
- `library` scopes to one SDK: `"boto3"` or `"aws-sdk-js"`

## Write back

Stigmer grows from agent contributions. If your agent hits a trap not in the network, register it so the next agent walks around it:

```python
from strands import tool

@tool
def stigmer_register(action: str, symbol: str, error: str, fix: str) -> str:
    """Register a fix with Stigmer. action: 'confirm' | 'append_thread' | 'new_receipt'."""
    # Posts to the Stigmer MCP endpoint; see https://stigmer.network/mcp
    ...
```
