The file

We split this skill into the rules it gives an agent

4 rules. About 0 are common, 0 are distinctive, and 4 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈0

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 4

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Use the new error code directly in your C/C++ source file (e.g., EVP_R_NEW_ERROR_CODE).

    line 13
  2. Very specific:

    Run util/make_errors.go, passing the lowercase library name (e.g., evp, ssl).

    line 16
  3. Very specific:

    Add the #define to the appropriate header in include/openssl.

    line 24
  4. Very specific:

    Update the .errordata file in crypto/err.

    line 25

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Adding a New Error Code

To add a new error code, you only need to use it in the source code and then run the error generation script. The script will automatically define it in the header and update the error database.

Steps

  1. Use the Error Code:
    • Use the new error code directly in your C/C++ source file (e.g., EVP_R_NEW_ERROR_CODE). It must start with the correct library prefix (e.g., EVP_R_, SSL_R_).
  2. Run the Error Generator:
    • Run util/make_errors.go, passing the lowercase library name (e.g., evp, ssl).
    • Example:
      go run util/make_errors.go evp
    • The script will automatically:
      • Find the new error code in the source.
      • Assign it a numeric value.
      • Add the #define to the appropriate header in include/openssl.
      • Update the .errordata file in crypto/err.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
