A release workflow for the Tempest app that prepares a version from its changelog, updates project files, and creates a Git tag and GitHub release.

Use it when you want to cut or tag a Tempest release. It reviews unreleased changes, suggests a semantic version, asks for confirmation, updates files, pushes the tag, and checks the GitHub release.

It removes the need to remember each release step and helps keep the changelog, app version, tag, and GitHub release aligned.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00058	$0.00825
Opus 5.5	$0.00023	$0.00330
Sonnet 5.5	$0.00012	$0.00165
Haiku 4.5	$0.00006	$0.00082

Security

Grade A, and why

release scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Release Skill

Cut a new release for Tempest. Follow these steps exactly.

Step 1: Determine the version

Read CHANGELOG.md and review the items under the ## Unreleased section.
If the Unreleased section has no meaningful entries (only empty headings), stop and tell the user there is nothing to release.
Based on the scope of changes, suggest a version number following semver. Show the user the summary and your suggested version.
Ask the user to confirm or provide a different version number. Do not proceed until confirmed.

Step 2: Determine today's date

Run date +%Y-%m-%d to get today's date. Do not guess or hardcode the date.

Step 3: Update CHANGELOG.md

Replace ## Unreleased with ## [VERSION] - YYYY-MM-DD (using the confirmed version and today's date).
Immediately after the new version heading and its content, add a fresh Unreleased section with empty subsections:

## Unreleased

### Added

### Fixed

### Changed

### Removed

Verify the edit looks correct by reading the first 25 lines of CHANGELOG.md.

Step 4: Update the app version

Update the version number in both places it appears:

electrobun.config.ts — change the version field in the app object to the new VERSION.
src/bun/pty-manager.ts — change the TERM_PROGRAM_VERSION value to the new VERSION.

Use the Edit tool for both changes.

Step 5: Detect VCS and commit

Check whether the repo uses jujutsu or git:
- If .jj directory exists: use jj commands
- Else if .git directory exists: use git commands
- NEVER use git commands for commits, bookmarks, or branches in a jj repo.

For jujutsu repos:

jj describe -m "Release VERSION"
jj new
jj bookmark set main -r @-
jj git push

For git repos:

git add CHANGELOG.md
git commit -m "Release VERSION"
git push

Step 6: Tag the release

For jujutsu repos:
```
jj tag set vVERSION -r main
```
Then push the tag via git (jj has no tag push support):
```
git push origin vVERSION
```

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
