newestcode

newestcode is a skill for Claude Code, Codex from TweekFawkes/prompts. It costs 162 tokens per session (2,892 once invoked), scanned A, original, Unlicense.

A Git skill that updates the current checkout with the latest merged code from the remote main branch. A checkout is the copy of a repository you are working in.

In plain words
What is it for?
Use it to fetch recent changes, report newly merged pull requests, and safely fast-forward, merge, or rebase the current branch.
Why use it?
It prevents work from continuing on stale code while protecting uncommitted changes, local commits, and feature branches.

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

newestcode 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/newestcode — Sync this checkout with the latest merged code

Other agents and the user merge PRs to main constantly. Work that started an hour ago may now be sitting on stale code. Your job: make THIS checkout reflect the latest origin/main, safely, and tell the user exactly what changed — then, if the running environment needs to match, offer to redeploy.

This is the download counterpart to the repo's "upload" skills. Don't confuse them:

  • /openpr, /landtomain, /gohome push this branch's work up to main.
  • /newestcode (this skill) pulls the world's latest main down into wherever we are. It creates no feature work and opens no PR.

The whole skill is built around one rule: never destroy or orphan local work to get newer code. A dirty tree, local commits, or a conflict means stop and surface, not force through.

Authoritative facts (verify, don't assume)

  • Remote: origin → your GitHub repo. Confirm with git remote -v.
  • Integration branch: main. If PRs merge as merge commits titled Merge pull request #N from <branch>, git log HEAD..origin/main reads as a clean list of the PRs you're about to pull in.
  • One .git, many worktrees. git fetch here updates origin/* for every worktree at once. But main is only ever checked out in ONE worktree (the canonical main checkout); every other worktree is on a feature/detached ref. The right integration move depends on which you're in — that's the phase-3 matrix.
  • "Latest code" has two layers. (a) The tracked files in this checkout matching origin/main — always in scope. (b) The thing actually running (your deployed dev environment, and your local virtualenvs) matching that code — only as fresh as the last deploy / dependency sync. Pulling commits fixes (a); it does not fix (b). Phase 5 bridges the gap.
  • Deploy source is the checkout it's RUN FROM. If your dev deploy syncs the repo copy it runs from onto the dev environment, a redeploy from a feature worktree silently reverts dev to that branch. Only offer the redeploy phase when on the canonical main checkout, unless the user explicitly wants this branch on dev.
  • Gitignored deploy artifacts are not "work." Seeded env files and per-worktree dependency/build caches don't show in git status and are reproducible — never force-add them or treat them as something to rescue.

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.
