name	no-way-to-prevent-this-memory-safety
description	Use when asked to generate a "no way to prevent this" / no-way-to-prevent-this satire post for a memory-safety CVE (out-of-bounds write/read, buffer/heap overflow, use-after-free, integer overflow) in a C or C++ project, given a CVE number or NVD link.

Generate a "no way to prevent this" memory-safety post

Overview

cmd/no-way-to-prevent-this is a Go generator that writes an Onion-style satire post ("'No way to prevent this' say users of only language where this regularly happens") for a memory-safety CVE. It fills a template from CLI flags and writes the result to lume/src/shitposts/no-way-to-prevent-this/<template>/<CVE>.md.

Workflow

1. Read the flags. Run go run ./cmd/no-way-to-prevent-this --help to confirm the current flag set before composing the command.
2. Look up the CVE. Fetch the NVD page (or the link the user gave) to extract:
   • the affected project name
   • the vulnerability type and a one-line technical description (function, root cause)
   • whether the project is C or C++ (C is the default; pass -c++ only for C++)
3. Find the real project homepage. Web-search for the official homepage — do NOT guess or construct the URL. Use the canonical site (e.g. https://libssh2.org/), not a package mirror or the GitHub repo unless that is genuinely the home.
4. Run the generator with the flags filled in (see below).
5. Read the generated file to confirm it reads correctly, then report the flag values you used and the output path.

Flags

Flag	Value
-cve	CVE id, e.g. CVE-2026-55200 (also names the output file)
-cve-link	the NVD/advisory URL
-project	affected project name
-project-link	the web-searched official homepage
-summary	concise technical description of the flaw and its impact; flows into the sentence "...to fix <summary>." Write it to read naturally there.
-c++	add only if the project is C++ (omit for C — it is the default)
-date	defaults to today; override only if backdating
-template	defaults to memory-safety; use supply-chain for that variant

Example

go run ./cmd/no-way-to-prevent-this \
  -cve "CVE-2026-55200" \
  -cve-link "https://nvd.nist.gov/vuln/detail/CVE-2026-55200" \
  -project "libssh2" \
  -project-link "https://libssh2.org/" \
  -summary "an out-of-bounds write in ssh2_transport_read() due to a missing upper bound check on the packet_length field, resulting in heap corruption and potential remote code execution"

Writes lume/src/shitposts/no-way-to-prevent-this/memory-safety/CVE-2026-55200.md.

Common mistakes

• Guessing -project-link. Always web-search for the homepage; a wrong/constructed URL ships a broken link.
• Passing -c++ for a C project. C is the default; the flag changes the post's wording. Only set it when the affected code is actually C++.
• A summary that doesn't fit the sentence. It is appended after "to fix " — read it back in context so the grammar works.
• Expecting stdout. The command is silent on success; verify by checking the new file under lume/src/shitposts/no-way-to-prevent-this/.
