update

A skill for updating and synchronizing Git Workflow files and Claude or Codex project-agent files from a source checkout or installed plugin. Git Workflow is a set of files and procedures for working with Git repositories.

In plain words
What is it for?
Use it to preview or apply updates, choose Claude or Codex targets, preserve customized files, migrate legacy files, or explicitly prune removed files.
Why use it?
It helps refresh managed files while showing changes, detecting custom edits, and optionally handling files removed from the source.

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

update 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 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.

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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Update Git Workflow

Follow runtime compatibility. Claude Code users invoke this as /update; Codex users invoke it as $update.

1. Parse options

  • --dry-run: calculate and display changes without writing.
  • --prune: include previously managed files that no longer exist in the source as removal candidates.
  • --force: overwrite customized managed files after still showing their diffs.
  • --host <claude|codex|both>: synchronize only the selected host assets; otherwise infer installed hosts and ask if ambiguous.
  • --source <path-or-git-url>: use an explicit Git Workflow checkout, plugin directory, or Git URL.

Unknown options are errors. Destructive pruning is never implied by --force alone.

2. Resolve project and source

Resolve the project root from Git, then accept either .git-workflow/, .claude/, or .codex/ as evidence of an existing installation. Resolve the source in this order:

  1. --source
  2. {PACKAGE_ROOT}, derived from the absolute physical directory containing this loaded SKILL.md as {SKILL_DIR}/../.., when it contains .codex-plugin/plugin.json
  3. PLUGIN_ROOT, then CLAUDE_PLUGIN_ROOT, as compatibility fallbacks only when the host cannot expose the loaded skill path; verify the manifest before accepting either value
  4. source recorded in .git-workflow/version.json

Never substitute an empty package variable or silently fall back to /scripts. If no complete source resolves, stop before writing and report every candidate checked.

For an explicit Git URL, clone it shallowly into a newly created temporary directory, validate it, and remove the temporary clone on success or failure. Do not perform a default network clone when an installed package root or ledger source is available. Validate that the source contains skills/, agents/, .codex/agents/, and a valid .codex-plugin/plugin.json. Stop without writing if it is incomplete.

3. Build the synchronization set

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.

update is a skill published in the GitHub repository rlajous/claude-code-commands (30 stars, last pushed 3d ago), licensed MIT. It adds 50 tokens to every session and 1,197 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
