pyobfus-review SKILL.md skillB

pyobfus-review from zhurong2020/pyobfus is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add zhurong2020/pyobfus/pyobfus-review@git:20260912.54b270c

Pins git:20260912.54b270c in mdr.lock. Pin the fingerprint instead.

Review a Python project for source-protection readiness without changing anything: what would break under obfuscation, which framework preset fits, which files the current config already excludes, and exactly which artifacts a build would emit. Use when the user asks "is this safe to obfuscate?", "what would protecting this break?", "review before we ship", or wants a pre-merge / CI check. Read-only by design — it never obfuscates, never writes deliverables, and never runs project commands. To…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Review a Python project with pyobfus (read-only)

Your job: tell the user what protecting this project would cost them, before
anyone changes a byte. You produce a judgement, not an artifact.

## Boundary — read this before running anything

This skill is read-only. Within it:

- **Never** run an obfuscation build, not even into a temp directory.
- **Never** write, move, or delete project files. `--check`, `--dry-run` and
  `--sarif` are the only pyobfus modes you use here. `--sarif PATH` writes one
  report file, so only use it when the user asked for CI output and name the
  path they chose.
- **Never** run the project's own commands (tests, entry points, install
  steps). Nothing in a review needs to execute the user's code.
- If the user actually wants a protected build, say so plainly and switch to
  the **pyobfus-protect** skill. Do not quietly start building.

## Step 1 — scan

Prefer the MCP tool if the `pyobfus-mcp` server is connected:

```
check_obfuscation_risks(path="src")
```

Otherwise use the CLI (`pip install pyobfus`):

```bash
pyobfus --check src/ --json
```

Both return the same shape: `severity_counts`, per-finding `file`/`line`/
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add zhurong2020/pyobfus/pyobfus-review@sha256:6387d9f8e02594a1

The line at the top of this page pins the label git:20260912.54b270c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
