At a glance

Invariants to preserve when touching .github/workflows/, build/Build.CI.GitHubActions.cs, or anything about which branches/tags trigger CI or publish packages.

  • Publish packages
  • Calls dotnet
  • Before editing a workflow YAML file
  • The CI generator source

What it does

Editing CI Workflows is an agent skill from Fallout-build/Fallout. Invariants to preserve when touching .github/workflows/, build/Build.CI.GitHubActions.cs, or anything about which branches/tags trigger CI or publish packages. Trigger before editing a workflow YAML file, the CI generator source, or branch trigger lists.

Its SKILL.md is about 470 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/ci-invariants.md`).

It sits in DevOps & Cloud, covering CI/CD. It works with GitHub Actions. The repository describes itself as: ☢️ Fallout — The C/.NET Build System.

When your agent uses it

  • Publish packages
  • Before editing a workflow YAML file
  • The CI generator source
  • Branch trigger lists

Example prompts

  • “Use the editing-ci-workflows skill to invariant to preserve when touching .github/workflows/, build/Build.CI.GitHubActions.cs, or anything about…”
  • “/editing-ci-workflows”

What it can do on your machine

Read from SKILL.md and the folder at commit 8333cc8. 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

    Shell commands in SKILL.md call:

    • dotnet

    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

Editing CI Workflows loads about 468 tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 69 tokens; SKILL.md has 160 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~69
When it runs · the whole SKILL.md, loaded when a task matches
~468
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.3k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 160 words (~468 tokens).

“Read references/ci-invariants.md in full before changing a workflow — most mistakes here are "looks fine, quietly breaks a gating assumption." The short version:”
