Walk NIST SSDF Phase 3 (Build) and file GitHub epics for the three build practices — PS.1 protecting code from unauthorized access and tampering, PW.5 secure coding practices, PW.6 hardening the compiler, interpreter, and build toolchain. Use when setting up or auditing a build pipeline, hardening CI, reviewing branch protection and commit signing, or when the user mentions NIST SSDF, SP 800-218, SSDF phase 3, secure coding standards, or the PS.1/PW.5/PW.6 practices.

The file

We split this skill into the rules it gives an agent

1 rule. About 0 are common, 0 are distinctive, and 1 is 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.

  • 1

    Very specific

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

≈ “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.

NIST SSDF Phase 3 — Build

Phase label: nist-phase-3-build

This skill files GitHub issues. It does not write code.

What this phase is about

Build is where source code is written and turned into executables. The security controls here are about protecting the code from tampering as it moves through the repository, writing it according to secure-coding practices, and configuring the toolchain (compilers, interpreters, build systems) so that vulnerabilities are eliminated or surfaced before testing.

Practices

Walk these in order — each one assumes the previous has landed. Read a practice's reference file only when you reach it, not up front.

PracticeNameReference
PS.1Protect All Forms of Code from Unauthorized Access and Tamperingreferences/ps1.md
PW.5Create Source Code by Adhering to Secure Coding Practicesreferences/pw5.md
PW.6Configure the Compilation, Interpreter, and Build Processes to Improve Executable Securityreferences/pw6.md

How to run

Follow the phase walkthrough protocol in references/protocol.md. Substitutions:

  • <PHASE_N> = 3
  • <PHASE_NAME> = Build
  • <PHASE_LABEL> = nist-phase-3-build
  • <PRACTICES> = PS.1, PW.5, PW.6

Phase epic title: [NIST Phase 3] Build.

The protocol confirms scope with the user, finds or creates the phase epic, then walks each practice — checking for an existing epic, asking whether to file, link, or skip, and updating the phase epic checklist as it goes. It never creates an issue without confirmation.

Adapting to the repo

The implementation notes in each reference file are deliberately generic, because this skill is meant to run against any repository. Before drafting an epic, read the repo's actual CI configuration, package manifests, and compiler settings, then rewrite the notes to name real files and real gaps. "Actions are pinned to floating tags in .github/workflows/ci.yml, not commit SHAs" is worth more than "pin your actions".

PW.5 in particular is about this codebase's secure coding standard. If the repo already documents one — in a contributing guide, an agent instructions file, or a style guide — the epic should point at it and close the gaps, not invent a second standard alongside it.

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.
