M3E: Skill for Claude Code

.claude/skills/majorupdate/SKILL.md

majorupdate is a skill for Claude Code from akaghef/M3E. It costs 72 tokens per session (352 once invoked), scanned A, original, MIT.

A release procedure for promoting the dev-beta Git branch to the main branch and adding a date-based version tag. Git is a system for tracking code changes and branches.

In plain words
What is it for?
Use it when releasing beta code: confirm the change, merge dev-beta into main, create and push the version tag, push main, and return to dev-beta.
Why use it?
It provides a repeatable way to publish a tested beta as a final release while preserving a merge record. It also defines how to handle conflicts and an existing tag.

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

majorupdate 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 5d 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.

What it actually says

Major Update Skill

Promote the current dev-beta branch to main (final release) with a date-based version tag.

Version format

Tag name: v + YYMMDD of today's date (e.g. v260402 for 2026-04-02). Derive the date from the current date at the time of execution.

Steps

Execute the following sequence in order:

  1. Confirm with the user before proceeding (this modifies main)
  2. Determine today's version tag: vYYMMDD
  3. git checkout main
  4. git merge dev-beta --no-ff -m "merge: dev-beta → main (beta promotion to final)"
  5. git tag <vYYMMDD> main
  6. git push origin main
  7. git push origin <vYYMMDD>
  8. git checkout dev-beta — return to the working branch

Notes

  • If there are merge conflicts, stop and report them to the user before proceeding
  • If the tag already exists (same-day re-launch), ask the user whether to overwrite or use a suffix (e.g. v260402-2)
  • Report the commit range pushed and the tag name on completion
  • Do not force-push or rewrite history

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.
