  • Calls git and bash

What it does

Squash is an agent skill from haacked/dotfiles. Squash each contributor's run of contiguous commits on the current branch into one, preserving authorship. CI snapshot commits (authored by bots) are preserved in place and reported.

Its SKILL.md is about 2k 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. The repository describes itself as: My dotfiles and scripts I use on dev machines.

When your agent uses it

  • Development work in your project

Example prompts

  • “/squash”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Commit Working-Directory Changes
  2. Gather Context
  3. Build the Plan
  4. Compose the Squash Messages
  5. Squash
  6. Report

What it can do on your machine

Read from SKILL.md and the folder at commit 23ffed9. 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:

    • git
    • bash

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

  • Network

    No URLs in SKILL.md. Its commands use git, 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

Squash loads about 2k tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 1,057 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~2k

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,057 words (~2,032 tokens).

“Squash the current branch's commits while preserving attribution. Each contributor's run of contiguous commits collapses into a single commit authored by that contributor. CI snapshot commits are left untouched.”
