MantaUI: Skill for OpenCode

.opencode/skills/release-manta/SKILL.md

release-manta is a skill for OpenCode from antoinedc/MantaUI. It costs 94 tokens per session (2,426 once invoked), scanned A, original, MIT.

A release procedure for MantaUI that finds changed components, updates their versions and changelog, merges the version change, and publishes release tags. A release tag is a Git label that starts the deployment process for a component.

In plain words
What is it for?
Use it to release the server, desktop apps, mobile app, website, or gateway from the latest main branch. It handles version bumps, changelog updates, tags, and deployment checks.
Why use it?
It prevents unchanged components from being released and avoids relying on a merge to the main branch alone. It also requires checking each deployment after tags are pushed.

Skill for OpenCode

Written for OpenCode: installed under .opencode/. Also seen: mentions AGENTS.md; $skill-name invocation; mentions OpenCode.

This is antoinedc/MantaUI's own configuration. It tells OpenCode how to work on MantaUI itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything MantaUI configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node scripts/release/check-changelog.mjs.

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.

Security

Grade A, and why

release-manta scanned grade A with 1 finding 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 2d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Release MantaUI

Releases are TAG-DRIVEN: merging to main deploys nothing. A release = (1) one bump PR merged to main, then (2) one tag per changed component, pushed one at a time, each verified. Read the "Release & CD pipeline" section of the repo AGENTS.md if anything below is unclear.

0. Start from latest main

git fetch origin --tags --prune
git status --short            # stash/commit stray changes first; never discard user work
git switch --detach origin/main   # main is often checked out in another worktree

1. Find the last release of each component

for p in server mac win web ios gateway; do
  echo "$p $(git tag -l "$p-v*" --sort=-creatordate | head -1)"
done

Use --sort=-creatordate, not version sort — tag schemes changed over time (server-v54 → server-v1.0.0).

2. Decide which components changed

Diff each component's paths from ITS last tag to origin/main (git diff --name-only <tag> origin/main -- <paths> | wc -l):

Component Tag Paths that make it "changed"
Server server-v* src/server src/shared scripts docs/opencode-tools docs/opencode-plugins-v2 package.json package-lock.json
Desktop (mac + win, always together) mac-v*, win-v* src/renderer src/main src/preload src/shared electron-builder*.yml assets package.json
iOS ios-v* mobile/native
Website web-v* website scripts/install.sh llms-install.md — and also whenever the box server is released (website/updates/server.json is published by the web deploy; without it boxes never see the update)
Gateway gateway-v* src/gateway only (a restart drops in-flight APNs pushes — never release it without gateway code changes)

Ignore pure docs/spec/test-only diffs when judging (docs/superpowers, *.test.*, AGENTS.md) — but a component with only those changes is "unchanged", not released.

Then list the commits for the changelog:

git log --format='%h %cs %s' <oldest-relevant-tag>..origin/main
# per-commit component attribution:
for c in $(git rev-list --reverse <tag>..origin/main); do
  git log -1 --format='%h %s' $c; git diff --name-only $c^ $c | cut -d/ -f1-2 | sort -u
done

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.
