What it does
Gsd Undo is an agent skill from open-gsd/gsd-core. Safe git revert. Roll back phase or plan commits using the phase manifest with dependency checks.
Its SKILL.md is about 280 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development. It works with Git. The repository describes itself as: Git. Ship. Done - Core. The licence is MIT.
When your agent uses it
- Development work in your project
Example prompts
- “/gsd-undo”
Requirements
- Pre-approved tools (allowed-tools): Read, Bash, Glob, Grep, AskUserQuestion
What it can do on your machine
Read from SKILL.md and the folder at commit 83aba44. 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:
ReadBashGlobGrepAskUserQuestion
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Gsd Undo loads about 283 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 101 words of instructions outside code blocks.
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.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Bash, Glob, Grep, AskUserQuestion
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.
