  • Fixing a failing build in the DDNS GitHub Actions workflows
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Changing Docker or Nuitka packaging without dropping platforms

What it does

The agent starts from the root AGENTS.md and the files involved: the workflows folder, docker folder, .github/patch.py, run.py, pyproject.toml and the relevant test scripts. It treats current workflow inputs, Dockerfiles, lockfiles and pinned settings as the source of truth rather than remembered versions, and identifies the affected artifact and platform set before editing. Python source, wheels and sdist, native binaries, Linux libc variants, containers, installers and scheduled-task validation are preserved unless the task changes support.

Changes are kept narrow: pull-request cache access stays restore-only, shared caches are written only from trusted branches, and compression, LTO, tests, caching or a platform are not disabled globally to fix one architecture failure without evidence. Existing build and offline end-to-end scripts are reused, and required checks stay independent of deployed sites. Release preparation verifies version changes, artifact names, checksums, release notes and rerun idempotency, then the agent runs the affected checks and reports matrix entries it did not exercise. It never publishes to PyPI, registries or GitHub Releases, and never touches release credentials or protected environments.

When your agent uses it

  • Fixing a failing build in the DDNS GitHub Actions workflows
  • Changing Docker or Nuitka packaging without dropping platforms
  • Preparing a release and checking versions, artifact names and checksums
  • Reviewing cache or matrix changes in CI

Example prompts

  • “The ARM container build is failing in CI. Find the cause and change as little as possible.”
  • “Prepare the next release and check the artifact names and checksums.”
  • “Add a new Linux libc variant to the Nuitka build matrix without touching the existing ones.”

Requirements

  • A checkout of the DDNS repository

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. Read the root AGENTS.md and the current files involved in the task
  2. Treat current workflow inputs, Dockerfiles, lockfiles, and pinned settings as
  3. Identify the affected artifact and platform set before editing. Preserve
  4. Keep pull-request cache access restore-only and write shared caches only from
  5. Make the narrowest coherent change. Do not disable compression, LTO, tests,
  6. Reuse existing build and offline E2E scripts. Keep required pull-request
  7. For release preparation, verify version transformations, expected artifact
  8. Run the affected package, binary, container, installer, and platform checks,

What it can do on your machine

Read from SKILL.md and the folder at commit 1c17f4e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

DDNS Build and Release Maintenance loads about 444 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 203 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~444

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Maintain DDNS GitHub Actions, Docker and Nuitka builds, packaging, installer validation, and release preparation while preserving matrices, caches, and protected publishing.

Build and Release Maintenance

  1. Read the root AGENTS.md and the current files involved in the task: .github/workflows/, docker/, .github/patch.py, run.py, pyproject.toml, and relevant test scripts.
  2. Treat current workflow inputs, Dockerfiles, lockfiles, and pinned settings as the source of truth. Do not rely on remembered versions, images, runners, or matrices.
  3. Identify the affected artifact and platform set before editing. Preserve Python source, wheel/sdist, native binaries, Linux libc variants, containers, installers, and scheduled-task validation unless the task explicitly changes support.
  4. Keep pull-request cache access restore-only and write shared caches only from trusted branches.
  5. Make the narrowest coherent change. Do not disable compression, LTO, tests, caching, or a platform globally to solve one architecture failure without evidence that the policy should change.
  6. Reuse existing build and offline E2E scripts. Keep required pull-request checks independent of deployed websites and external mutable services.
  7. For release preparation, verify version transformations, expected artifact names, checksums, release notes, and rerun idempotency.
  8. Run the affected package, binary, container, installer, and platform checks, then report any matrix entries not exercised.

Do not publish to PyPI, container registries, or GitHub Releases. Do not access release credentials, modify repository settings, bypass protected environments, or weaken required checks.
