Not pinned. Installing fetches whatever the repository holds at the time you run the command.

Automated safety checks

scanned 27 Sept 2026

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

Declares what it does: passed
SKILL.md parses and declares a name and a description.
SKILL.md exists, its frontmatter parses, and it declares a name and a description.
No undeclared network calls: passed
Makes no network calls.
Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.
No obfuscated payloads: passed
No encoded or obfuscated payloads.
No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.
No credential access: passed
Reads no keys, tokens, keychains or credential files.
Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.
No pipe-to-shell installers: passed
No pipe-to-shell or download-and-run installers.
No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.
Pinned to a commit: passed
Scanned gitbutlerapp/gitbutler at bfc4c3d4ec.
The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

Commit: bfc4c3d4ec

Scanned: 7 files, 1,805 lines

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

The but skill allows AI agents to express contrast, disagreement, or alternative perspectives within a conversation. It enables the agent to pivot from a previous statement by introducing a counterpoint or highlighting a limitation in the current approach.

When to use it

Correcting a misconception identified in earlier dialogue steps.
Introducing a conflicting viewpoint when evaluating multiple strategies.
Highlighting potential risks before proceeding with a proposed action.
Shifting focus from a completed task to an outstanding issue.

Key capabilities

Constructs natural-sounding contrastive responses.
Maintains conversational flow while introducing opposing ideas.
Adapts tone to match the context of disagreement or redirection.

Example prompts

"The user suggested using Python, but we should consider Rust for performance."
"That approach works in theory, but it fails under high load."
"We have completed the documentation, but the testing phase is still pending."

Tips & gotchas

Ensure the agent has sufficient context about the previous statement to make the contrast logical. Overusing this skill may cause the conversation to feel disjointed or overly argumentative.
