What it does

Agm Validate Change is an agent skill from Draculabo/AntigravityManager. Select and run the smallest reliable validation set for an Antigravity Manager worktree change. Use after implementing repository changes or before claiming they are validated; do not use for read-only analysis.

Its SKILL.md is about 600 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, covering Git worktrees. It works with Google Gemini. The repository describes itself as: Antigravity Manager is a powerful Electron-based application designed to manage accounts and processes for the Antigravity application. It provides a seamless interface for…

When your agent uses it

  • Read-only analysis
  • Tasks that involve Git worktrees

Example prompts

  • “/agm-validate-change”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Confirm the repository root, branch and worktree status.
  2. Inspect staged, unstaged and relevant untracked files without modifying unrelated user work.
  3. Classify each changed path as documentation/governance, renderer UI, routing, IPC/preload, Electron main lifecycle, persistence/security…
  4. Identify behavior that crosses more than one category; those paths need evidence from each affected side.

What it can do on your machine

Read from SKILL.md and the folder at commit 0f1b99b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    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

Agm Validate Change loads about 596 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 289 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~596

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 passed

The automated check found no risky patterns in SKILL.md.

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 289 words (~596 tokens).

“Validate the behavior a diff can affect without reflexively running the full repository suite. Testing strategy owns the change-to-evidence mapping; the nearest AGENTS.md owns additional requirements.”
