What it does

Crimson Release is an agent skill from banteg/crimson. Prepare or publish a Crimson patch, minor, or development release with changelog notes, version and lock updates, validation, and tag-triggered publishing.

Its SKILL.md is about 900 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Development, covering Changelog and release notes. The repository describes itself as: a faithful rewrite of crimsonland 1.9.93 from 2003.

When your agent uses it

  • Tasks that involve Changelog and release notes

Example prompts

  • “/crimson-release”

Workflow steps

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

  1. Inspect the branch and git status --porcelain. Use an up-to-date master or a clean isolated worktree based on it; preserve unrelated work…
  2. Run just check before changing the version. Resolve new failures before continuing. For gameplay changes, also check the final gameplay…
  3. Review commits since the previous release. Add ## to CHANGELOG.md, using its existing player-facing style and an Under the hood section…
  4. Run uv version --bump (or the explicit version), then uv lock. Inspect the diff: the package and its editable lock entry should match…
  5. Validate the release section exactly as the workflow extracts it

What it can do on your machine

Read from SKILL.md and the folder at commit f8e7434. 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:

    • uv
    • git
    • just

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

  • Network

    No URLs in SKILL.md. Its commands use uv 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

Crimson Release loads about 896 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 456 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~896

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 456 words (~896 tokens).

“Read the extracted notes and run uv lock --check, uv build, and checks appropriate to any additional edits. Confirm the wheel/sdist version matches. If preparation is all that was requested, present the diff and validation results here.”
