What it does

Release Fetch Changelog is an agent skill from shopsys/shopsys. Calls the GitHub REST API via gh to generate release notes for the given tag (the same content the "Generate release notes" button produces on the web UI) and inserts the result into the matching CHANGELOG-X.Y.md file. Used standalone or by the /release orchestrator when UpdateChangelogReleaseWorker is up next.

Its SKILL.md is about 1.2k 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 Changelog and release notes. It works with GitHub. The repository describes itself as: Main repository for maintaining Shopsys Platform packages. Open for ISSUES and PULL REQUESTS.

When your agent uses it

  • Tasks that involve Changelog and release notes

Example prompts

  • “Generate release notes”
  • “Use the release-fetch-changelog skill to call the GitHub REST API via gh to generate release notes for the given tag (the same content the "Generate…”
  • “/release-fetch-changelog”

Workflow steps

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

  1. gh auth status succeeds.
  2. The CHANGELOG file exists at the resolved path. If not, ask the operator to confirm the path with --changelog-file.
  3. gh release view returns "release not found" — bail out if the tag/release already exists.

What it can do on your machine

Read from SKILL.md and the folder at commit a994ffa. 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
    • git

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

  • Network

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

Release Fetch Changelog loads about 1.2k tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 534 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~85
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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 534 words (~1,246 tokens).

“Automates the GitHub "Generate release notes" copy-paste step using the gh CLI. The GitHub-native generator stays the source of truth — this skill does not draft the changelog body itself.”
