At a glance

Complete YAML schema reference for File and FileSet resources.

  • Writing manifests to manage files (CODEOWNERS
  • SKILL.md covers Core Rules, File, FileSet and High-Value Gotchas, plus 1 more section
  • Calls gh
  • More repositories

What it does

File Manifest is an agent skill from babarot/gh-infra. Complete YAML schema reference for File and FileSet resources. Use when writing manifests to manage files (CODEOWNERS, LICENSE, CI workflows, etc.) in one or more repositories, including templating, patches, reconcile modes, delivery method, and import-into behavior.

Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/fileset.md`, `references/patches.md` and `references/reconcile-and-delivery.md`).

It sits in Development. It works with GitHub. The repository describes itself as: Declarative GitHub infrastructure management via YAML. The licence is MIT.

When your agent uses it

  • Writing manifests to manage files (CODEOWNERS
  • More repositories
  • Including templating
  • Reconcile modes

Example prompts

  • “/file-manifest”

What it can do on your machine

Read from SKILL.md and the folder at commit 7ef15b2. 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:

    • gh

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

  • Network

    No URLs in SKILL.md. Its commands use gh, which can reach the network depending on how they are called.

    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

File Manifest loads about 864 tokens when it runs, and up to ~2.3k if it reads all its reference files. Until then it costs about 70 tokens; SKILL.md has 249 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~70
When it runs · the whole SKILL.md, loaded when a task matches
~864
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.3k

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.

File Manifest Reference

Use this skill for file-distribution manifests. Keep the main body small and open references only when the request needs them.

Core Rules

  • File is parsed as a one-repo FileSet internally, but you still author the simpler shape
  • Each file entry requires path and exactly one of content or source
  • via defaults to push
  • reconcile defaults to additive
  • patches are applied after template expansion

File

yaml
apiVersion: gh-infra/v1
kind: File
metadata:
  owner: my-org
  name: my-repo
spec:
  files:
    - path: .github/CODEOWNERS
      content: |
        * @username
    - path: LICENSE
      source: ./templates/LICENSE
  via: push
  commit_message: "ci: sync managed files"

Key fields:

  • files: required
  • via: push or pull_request
  • commit_message, branch, pr_title, pr_body: delivery controls. commit_message, pr_title, pr_body accept <% .Repo.Name %>, <% .Repo.FullName %>, <% .Source.URL %> (env GH_INFRA_SOURCE_URL, set in CI); see references/reconcile-and-delivery.md
  • files[].vars: template variables
  • files[].patches: unified diff patches
  • files[].reconcile: additive, authoritative, create_only
  • files[].executable: true for mode 100755, false for 100644, omitted keeps the current mode

Read these references as needed:

FileSet

Use FileSet to distribute shared files to many repositories.

yaml
apiVersion: gh-infra/v1
kind: FileSet
metadata:
  owner: my-org
  name: shared-ci          # optional; names the FileSet, does not select repos

spec:
  repositories:
    - gomi                # simple string
    - enhancd
    - name: gh-infra      # struct with overrides
      overrides:
        - path: .github/CODEOWNERS
          content: |
            * @username @co-maintainer

  files:
    - path: .github/CODEOWNERS
      content: |
        * @username

    - path: LICENSE
      source: ./templates/LICENSE

  via: push

Each repository entry is either:

  • a simple repo name string
  • an object with name and optional overrides

Overrides replace the matching base entry by path for that repository only.

High-Value Gotchas

  • Prefer patch files over inline patch blocks for files with tabs
  • Patch context must match template-expanded content, not raw template source
  • github:// sources are import hard-skips because there is no local write target
  • Shared local source files in FileSet often default to the patch write action in import --into
  • create_only affects apply behavior, but import can still update the local master template
