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 | $0.01278 | $0.01278 |
| Opus 5 | $0.00639 | $0.00639 |
| Sonnet 5 | $0.00256 | $0.00256 |
| Haiku 4.5 | $0.00128 | $0.00128 |
Grade D, and why
aws-auth AGENTS.md scanned grade D with 2 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 yesterday.
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.
Strips warnings and disclaimersmediumAnti-refusal
Omitting safety caveats hides risk from the user and is a common jailbreak preamble.
Ensure `make build` (or `./install.sh`) builds and installs cleanly without warnings. Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
- `credentials_manager.py`: Manages `~/.aws/credentials`, active profile tracking (`~/.aws-auth/current_profile`), and atomic POSIX file writes. How it starts
The opening of the file, as written. The whole thing — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AI Agent Development Guidelines: aws-auth
You are an expert Senior Python & Cloud Infrastructure Engineer pair-programming on aws-auth, an open-source, high-performance AWS SSO CLI tool and Model Context Protocol (MCP) server.
Follow these rules and patterns when designing, implementing, refactoring, and testing features.
🎯 Repository Purpose & Tech Stack
- Purpose: Zero-boilerplate AWS SSO authentication, smart MRU role discovery, session-scoped named profile switching via
export AWS_PROFILE, EKS/EC2 DevOps integration, and native MCP stdio server for AI agents. - Language: Python 3.10+ (standard library +
boto3,requests,mcp). - Packaging & Build:
pyproject.toml(Setuptools) + PyInstaller single-file standalone binaries (dist/aws-auth,dist/aws-auth.exe). - Platforms: Linux (Debian/Ubuntu, RedHat), macOS (Universal), Windows (PowerShell/cmd), WSL2 (with Windows host browser bridge).
🏗️ Architecture & Module Map
Maintain Single Responsibility across modules in aws_auth/:
cli.py: Argument parsing (argparse), CLI dispatch, and JSON output formatting.auth_manager.py: Orchestrates device authorization flow, token acquisition, role assumption, and profile generation.credentials_manager.py: Manages~/.aws/credentials, active profile tracking (~/.aws-auth/current_profile), and atomic POSIX file writes.profile_manager.py: Profile listing, interactive switching, and caller identity verification.token_manager.py: OIDC client registration, SSO access token caching, and token expiration safety margins.local_browser_manager.py: Cross-platform browser launcher with WSL2 detection to launch the host Windows browser.sso_client.py: Low-level AWS SSO and OIDC API wrapper (device code flow, account listing, role listing).user_interface.py: ANSI tables, fuzzy substring filters, and interactive CLI prompts.mcp_server.py: Model Context Protocol server exposing AWS tools over stdio for LLM assistants.ec2_manager.py/eks_manager.py: AWS resource discovery, SSM terminal sessions, and kubeconfig updates.scripts/check_credentials.py: Pre-commit, commit-msg, and pre-push policy and secret scanner.install.sh/install.ps1: Automated installers with idempotent shell integration wrappers.
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-auth AGENTS.md is an instructions file published in the GitHub repository N0mansky/aws-auth (0 stars, last pushed 2d ago), licensed MIT. It adds 1,278 tokens to every session, about $0.0064 per session on Opus 5. A static security scan graded it D with 2 findings (strips warnings and disclaimers, reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-18.
