What it does

Hotfix is an agent skill from microsoft/roosterjs, published by the product's own GitHub organization. Proposes a scoped version bump for a roosterjs hotfix. Given one or more commits provided by the user, determines which packages had files changed by those commits, bumps the version only for the affected version groups, and creates a draft PR. Use when asked to do a hotfix, a scoped/targeted version bump, or to release only specific commits.

Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: roosterjs is a framework-independent javascript rich text editor.

When your agent uses it

  • Asked to do a hotfix
  • A scoped/targeted version bump
  • Release only specific commits

Example prompts

  • “Use the hotfix skill to propose a scoped version bump for a roosterjs hotfix. An agent skill from microsoft/roosterjs”
  • “/hotfix”

Workflow steps

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

  1. Confirm the commits
  2. Check for uncommitted changes
  3. Switch to release and pull latest
  4. Determine the files changed by the provided commits
  5. Create a new branch based on release
  6. Determine the SemVer bump for each affected group
  7. Update versions.json
  8. Build and test
  9. Commit the change
  10. Push the branch
  11. Create a draft PR
  12. Show the PR link

What it can do on your machine

Read from SKILL.md and the folder at commit c9e400c. 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:

    • git
    • gh
    • yarn

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

  • Network

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

Hotfix loads about 2.7k tokens when it runs. Until then it costs about 88 tokens; SKILL.md has 1,168 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~88
When it runs · the whole SKILL.md, loaded when a task matches
~2.7k

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 1,168 words (~2,690 tokens).

“This skill performs a scoped version bump for a roosterjs hotfix. Unlike the full version-bump skill (which bumps everything merged into master since the last release), this skill bumps the version only for the packages whose files were changed by…”
