What it does

PR Snapshot Release is an agent skill from mastra-ai/mastra. Guide a Mastra maintainer through publishing an npm snapshot from a pull request or a specified repository branch. Use when asked to release, publish, or create a PR snapshot, branch snapshot, canary package build, or branch-specific npm tag. Performs source and branch preflight checks, requires confirmation before the irreversible publish, dispatches the existing Publish to npm workflow, monitors it, and reports installable package tags.

Its SKILL.md is about 1.4k 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 Development, covering Deployment and Pull requests. It works with Mastra and npm. The repository describes itself as: Mastra is the modern TypeScript framework for AI-powered applications and agents.

When your agent uses it

  • Asked to release
  • Create a PR snapshot
  • Branch snapshot
  • Canary package build

Example prompts

  • “/pr-snapshot-release”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Resolve the source
  2. Verify the exact branch revision
  3. Choose a custom npm tag
  4. Confirm and dispatch
  5. Monitor the run
  6. Verify and report

What it can do on your machine

Read from SKILL.md and the folder at commit b98829a. 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
    • npm
    • git
    • pnpm

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

  • Network

    No URLs in SKILL.md. Its commands use gh, npm, git and pnpm, 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

PR Snapshot Release loads about 1.4k tokens when it runs. Until then it costs about 116 tokens; SKILL.md has 601 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~116
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

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 601 words (~1,410 tokens).

“Publish a snapshot from a PR or a specified branch using .github/workflows/npm-publish.yml. Snapshot publishing is manual, works only for branches in mastra-ai/mastra, and publishes real immutable package versions to npm.”
