aws-iot-securetunneling-localproxy is a C++ reference implementation of a local proxy that carries a single-threaded TCP client or server connection through AWS IoT Secure Tunneling. It is used to connect devices or services across a tunnel, with proxy instances running at both ends on Linux, Windows, or macOS. The catalogue instruction supports building, configuring, and running this proxy.
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.

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 | $0.02164 | $0.02164 |
| Opus 5 | $0.01082 | $0.01082 |
| Sonnet 5 | $0.00433 | $0.00433 |
| Haiku 4.5 | $0.00216 | $0.00216 |
Grade C, and why
aws-iot-securetunneling-localproxy AGENTS.md scanned grade C 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 5d 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.

AGENTS.md
Guidance for agents (and humans) making commits to
aws-iot-securetunneling-localproxy. This repo is a C++14 / CMake project
(not a Brazil package); it uses Boost.Asio/Beast, protobuf and OpenSSL, and a
Nix flake provides the formatter. See CONTRIBUTING.md for the project's
overall contribution policy (issues, PRs, CLA).
TL;DR commit checklist
Before every commit:
- Make one focused, logical change.
- Update the unit tests and UATs the change affects (see below).
nix fmt— format the tree (must end clean / idempotent).- Run the spelling check (see Spelling); add legitimate technical terms to
misc/dictionary.txtif flagged. - Build and run the unit tests (see below); ensure they pass.
- Stage only the files for this change; write a clear message (see below).
- Never commit to
main; never force-push a shared branch without coordinating.
Branching
- Work on a feature branch named
dev/<short-kebab-name>(e.g.dev/security-audit-findings). - Per
CONTRIBUTING.md, work against the latestmainand keep a change focused on one thing — don't reformat unrelated code. - History may be reworded/rebased only while the branch has not been pushed. Once shared, prefer new commits; rewriting then requires a coordinated force-push.
One change per commit
- Each commit should be a single, self-contained change (one fix / one feature). Don't mix unrelated changes.
- Keep the tests and docs for a change in the same commit as the change (e.g. URL-parsing tests live with the URL-parsing fix).
- With each feature or fix, update the unit tests (
test/, Catch2) and the UATs (uat/) as needed so behavior stays covered: add cases for new behavior and adjust existing ones instead of deleting them. - Keep formatting in the same commit as the code it applies to. Normally
this is automatic: just run
nix fmtbefore committing. (Redistributing formatting across already-made commits is only needed if it was applied after the fact — not part of the normal flow.)
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-iot-securetunneling-localproxy AGENTS.md is an instructions file published in the GitHub repository aws-samples/aws-iot-securetunneling-localproxy (89 stars, last pushed 3d ago), licensed Apache-2.0. It adds 2,164 tokens to every session, about $0.0108 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
