What it does

Packaging Notarization is an agent skill from robinebers/openusage. Prepare and troubleshoot packaging, signing, and notarization workflows for macOS distribution. Use when asked to archive a Mac app, validate bundle structure, reason about notarization readiness, or explain distribution-only failures.

Its SKILL.md is about 380 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile. It works with macOS. The repository describes itself as: Burning through your subscriptions too fast? Paying for stuff you never use? Stop guessing. OpenUsage is free and open source. The licence is MIT.

When your agent uses it

  • Asked to archive a Mac app
  • Validate bundle structure
  • Reason about notarization readiness
  • Explain distribution-only failures

Example prompts

  • “/packaging-notarization”

Workflow steps

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

  1. Confirm the distribution goal.
  2. Inspect the artifact.
  3. Inspect signing and runtime prerequisites.
  4. Explain notarization readiness or failure.

What it can do on your machine

Read from SKILL.md and the folder at commit cb21465. 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

Packaging Notarization loads about 383 tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 154 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~383

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.

Packaging & Notarization

Quick Start

Use this skill when the work is about shipping the app rather than merely running it locally: archives, exported app bundles, notarization readiness, hardened runtime, or distribution validation.

Workflow

  1. Confirm the distribution goal.

    • Local archive validation
    • Signed distributable app
    • Notarization troubleshooting

  2. Inspect the artifact.

    • Validate app bundle structure.
    • Check nested frameworks, helper tools, and entitlements.

  3. Inspect signing and runtime prerequisites.

    • Hardened runtime
    • Signing identity
    • Nested code signatures
    • Required entitlements

  4. Explain notarization readiness or failure.

    • Separate packaging issues from trust-policy symptoms.
    • Point to the minimum follow-up validation commands.

Guardrails

  • Do not present notarization as required for ordinary local debug runs.
  • Call out when you lack the actual exported artifact and are inferring from project settings.
  • Keep advice concrete and verifiable.

Output Expectations

Provide:

  • what artifact or settings were inspected
  • whether the app looks distribution-ready
  • the top missing prerequisite or failure mode
  • the next validation or repair step
