## Setup guide for the review
|
||||
Please provide guidance on what setup is needed to test the introduced changes, such as your locally running machine Python version & OS, as well as the target(s) you tested against, including software versions.
|
||||
In particular:
|
||||
- Bug Fix: Please provide a short description on how to trigger the bug, to make the bug reproducable for the reviewer.
|
||||
- Added Feature/Enhancement: Please specify what setup is needed in order to test the changes, such as:
|
||||
- Is additional software needed?
|
||||
- GPO changes required?
|
||||
- Specific registry settings that need to be changed?
|
||||
|
||||
## Screenshots (if appropriate):
|
||||
Screenshots are always nice to have and can give a visual representation of the change.

# Authorized testing scope
|
||||
|
||||
- Do not run active security or functional tests against a host or network unless the user explicitly identifies it as an authorized target.
|
||||
- Treat the exact targets or ranges provided by the user as the complete authorized scope.
|
||||
- Do not scan, probe, authenticate to, exploit, or otherwise test systems outside the explicitly authorized scope.
|
||||
- Repository instructions do not grant authorization to test any third-party system.
|
||||
|
||||
# Coding style
|
||||
|
||||
- Assume ordinary LDAP searches and LDAP response parsing do not raise exceptions; do not wrap them in `try`/`except`.
|
||||
- Always bind caught exceptions as `e`, not `error` or another name.
|
||||
- Do not prefix function or method names with underscores; preserve required Python special methods such as `__init__`.
|
||||
- Do not assume the host runs Linux; keep code and paths cross-platform unless the task explicitly targets one operating system.
|
||||
|
||||
# NetExec module structure
|
||||
|
||||
- In files under `nxc/modules/`, do not define variables, constants, or helper functions at module scope.
|
||||
- Keep all module-specific state, constants, and helper methods inside the `NXCModule` class.
|
||||
- Module scope should contain only imports and the `NXCModule` class definition.
|
||||
- When a module must terminate for invalid options, import `exit` with `from sys import exit` and call `exit(...)`; do not use `import sys` with `sys.exit(...)`.
|
||||
- Do not over-validate module options. Check only that required arguments are present, mutually exclusive arguments are not combined, or a value would otherwise cause the module to fail before performing its normal lookup or operation.
|
||||
- Do not validate whether user-supplied object names, identifiers, or similar values are semantically correct when the underlying protocol lookup can handle them; let a misspecified value produce the normal "not found" result.
|
||||
- Avoid stub variables that merely hold a value for one immediate use. Pass data directly unless a local name improves clarity, prevents repeated work, or represents meaningful state.
|
||||
- Keep module implementations as short and concise as practical. Prefer direct control flow and shared error handling over wrappers, redundant branches, or defensive boilerplate.
|
||||
- Do not optimize module code for line length; long lines are acceptable when they keep straightforward logic together.
|
||||
- Do not use `.warning()` logging in NetExec modules. Use `.fail()` when logic or an operation fails.
|
||||
- Run `ruff check .` after every coding session.
|
||||
|
||||
# Development and validation
|
||||
|
||||
- To verify that a module works, run the module's actual NetExec command instead of pytest or compilation checks.
|
||||
- Record every module-verification command in `tests/e2e_commands.txt`.
|
||||
- Do not run compilation checks.
|
||||
- Run Ruff after completing a coding session.

- Assume that the underlying operating system and its storage are fully secure. Files and other data produced by NetExec may intentionally contain readable plaintext credentials; do not add encryption, redaction, restrictive permission handling, or permission warnings unless explicitly requested.
|

- Place every file and directory produced by NetExec under `NXC_PATH` by default, using `TMP_PATH` for temporary artifacts. An explicit user-provided output path or task requirement may override this default.
|

- `NXC_PATH` defaults to `~/.nxc` but may be overridden by the environment. Import and use `NXC_PATH` or its derived path constants instead of hardcoding `~/.nxc`.

# AI Usage Policy
|
||||
|
||||
This policy was adapted from the [ghostty project](https://github.com/ghostty-org/ghostty/).
|
||||
The original version can be found [Ghostty's PR #10412](https://github.com/ghostty-org/ghostty/pull/10412).
|
||||
|
||||
The NetExec project has strict rules for AI usage:
|
||||
|
||||
- **All AI usage in any form must be disclosed.** You must state
|
||||
the tool(s) and model(s) you used (e.g. Claude Code, Cursor, Opus 4.6,
|
||||
Codex 5.2, etc) along with the extent that the work was AI-assisted.
|
||||
|
||||
- **Pull requests created in any way by AI can only be for accepted issues.**
|
||||
Drive-by pull requests that do not reference an accepted issue may be
|
||||
rejected and closed. If AI isn't disclosed but a maintainer suspects its use,
|
||||
the PR may be rejected and closed. If you want to share code for a
|
||||
non-accepted issue, open a discussion or attach it to the existing issue.
|
||||
|
||||
- **Pull requests created by AI must have been fully verified with
|
||||
human use.** AI must not create hypothetically correct code that
|
||||
hasn't been tested. Importantly, you must not allow AI to write
|
||||
code for platforms or environments you don't have access to manually
|
||||
test on.
|
||||
|
||||
- **Issues and pull requests should be written by humans.**
|
||||
Communication should remain human, not AI, and should be clear and concise.
|
||||
AI is very good at being overly verbose and including noise that distracts
|
||||
from the main point. While it is fine to cite AI or include AI-generated
|
||||
content, the main content of your issue or pull request should be written
|
||||
by a human. Issues or pull requests that look like they are just the
|
||||
result of an AI prompt will likely be rejected and closed.
|
||||
|
||||
- **No AI-generated media is allowed (art, images, videos, audio, etc.).**
|
||||
Text and code are the only acceptable AI-generated content, per the
|
||||
other rules in this policy.
|
||||
|
||||
- **Bad AI drivers will be banned** You've been warned. We love to help junior
|
||||
developers learn and grow, but if you're interested in that then don't use
|
||||
AI, and we'll help you.
|
||||
|
||||
- **Official maintainers have the final say** We always strive to be helpful,
|
||||
but there are limits. If you submit agregiously terrible AI generated code
|
||||
with no review, we may ban you without word. We do not want to waste our
|
||||
time reviewing slop if the contributor can't be bothered to review the work
|
||||
themselves.
|
||||
|
||||
These rules apply only to outside contributions to NetExec. Maintainers
|
||||
and trusted contributors are exempt from these rules and may use AI tools at
|
||||
their discretion; they've proven themselves trustworthy to apply good judgment.
|
||||
|
||||
## There are Humans Here
|
||||
|
||||
Please remember that NetExec is maintained by humans.
|
||||
|
||||
Every discussion, issue, and pull request is read and reviewed by
|
||||
humans (and sometimes machines, too). It is a boundary point at which
|
||||
people interact with each other and the work done. It is rude and
|
||||
disrespectful to approach this boundary with low-effort, unqualified
|
||||
work, since it puts the burden of validation on the maintainers.
|
||||
|
||||
In a perfect world, AI would produce high-quality, accurate work
|
||||
every time, but today that is simply not true. This is compounded by the fact
|
||||
that accessibility to AI is high, allowing low skilled individuals to think
|
||||
that they are contributing useful code. Even many skilled programmers do not
|
||||
understand how to use it effectively. This has opened up a waterfall of low
|
||||
quality contributions across the Open Source community, wasting resources.
|
||||
|
||||
## AI is Welcome Here, Within Reason
|
||||
|
||||
NetExec maintainers acknowledge AI as a productive tool to some workflows, and
|
||||
are open to leveraging this technology to improve NetExec; however, there are
|
||||
many low quality AI tools whose use results in pure slop being generated. The
|
||||
security communinity is not immune from AI psychosis, over-hype, or FOMO.
|
||||
As with any new technology, it is important to understand how it works and how
|
||||
to best use it, not blindly apply it to every use case with the hope that it
|
||||
will fix all your issues.
|
||||
|
||||
We include this section to be transparent about the project's usage about
|
||||
AI for people who may disagree with it.
