What it does

Gpg Signing is an agent skill from Prorise-cool/Claude-Code-Multi-Agent. Comprehensive guide to GPG commit signing. Set up, configure, and troubleshoot GPG commit signing. Fix GPG signing errors, configure passphrase caching, verify commit signatures. Use when working with Git commit signing, GPG keys, commit verification, signature verification, GPG configuration, or when encountering GPG signing errors. Covers Windows (Gpg4win), macOS (GPG Suite), Linux (gnupg), and WSL installation and setup.

Its SKILL.md is about 3.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `references/passphrase-caching.md`, `references/quick-reference.md` and `references/security-best-practices.md`).

It sits in Backend & APIs, covering Caching, Commit messages and Webhooks. It works with Linux, GitHub, macOS and Git. The repository describes itself as: Claude-Code-Multi-Agent驱动的新一代AI编程助手生态系统，基于Claude Code构建的智能代理协调工作空间，实现从需求到交付的全流程自动化开发.

Workflow steps

What it can do on your machine

Read from SKILL.md and the folder at commit 0dc1305. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Read
- Bash
- Glob
- Grep
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- git
- apt
- winget
- brew
- dnf
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- github.com
- gpg4win.org
- gpgtools.org
Also links to:
- docs.github.com
- gnupg.org
- git-scm.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- CORRECT_KEY_ID
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Gpg Signing loads about 3.9k tokens when it runs, and up to ~25k if it reads all its reference files. Until then it costs about 110 tokens; SKILL.md has 1,024 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~110
When it runs · the whole SKILL.md, loaded when a task matches: ~3.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~25k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,024 words (~3,860 tokens).
