Agent skills automate the full auto-fix workflow in Claude Code. Instead of manually prompting your assistant to fetch comments and apply fixes, invoke a skill and let it handle the entire loop. All three skills (check-pr, cli-review, and greploop) are open source and available at github.com/greptileai/skills.
Prerequisites:

​
Install

Install all three skills with the skills CLI (recommended):
To install into a single project instead of globally, run this from the project root:

​
Alternative: git clone

Clone the skills into your Claude Code skills directory, then symlink each skill into place. See the Claude Code skills docs for more on how skill discovery works.

​
check-pr

Checks a pull request for unresolved review comments, failing status checks, and incomplete descriptions — then fixes and resolves them.

​
Usage

Or with a specific PR number:
If no PR number is given, the skill auto-detects the PR for your current branch.

​
What It Does

1

Waits for pending checks

Polls until all CI and review bot checks (Greptile, linters, etc.) reach a terminal state. This ensures all comments are available before analysis.
2

Analyzes the PR

Evaluates four areas:
  • Status checks — Are CI checks passing or failing?
  • PR description — Is it complete? Any TODOs or placeholders?
  • Review comments — Inline comments from Greptile, linters, and human reviewers
  • General comments — Discussion threads and bot notifications
3

Categorizes issues

Each issue is classified as:
4

Fixes and resolves

If there are actionable items, the skill makes the fixes, commits, pushes, and resolves the corresponding review threads.

​
cli-review

Runs a Greptile review from your local checkout with the Greptile CLI and summarizes the findings. Use it to get Greptile feedback before opening a PR.

​
Usage

Run it from inside a git repository. The skill reviews the current local branch. /cli-review only needs the Greptile CLI; it doesn’t use gh or the Greptile MCP server. Commit your changes first. The review covers committed changes on the current branch, not uncommitted edits.

​
What It Does

1

Checks for the Greptile CLI

Confirms greptile is installed. If it’s missing, the skill asks before installing it with npm i -g greptile.
2

Ensures authentication

Runs greptile whoami and prompts you through greptile login if needed.
3

Runs the review

Runs greptile review --json, falling back to greptile review --agent if JSON output isn’t supported.
4

Summarizes findings

Reports the review status, number of findings, highest-severity issues first, and the files that need edits.

​
greploop

Iteratively improves a PR until Greptile gives it a 5/5 confidence score with zero unresolved comments. Triggers a Greptile review, fixes all actionable comments, pushes, re-triggers, and repeats.

​
Usage

Or with a specific PR number:

​
What It Does

1

Triggers a Greptile review

Pushes the latest changes and waits for the Greptile review check to complete.
2

Parses review results

Reads the confidence score (e.g. 3/5) and fetches all unresolved inline comments from Greptile.
3

Fixes actionable comments

For each unresolved comment, reads the file in context, determines if a code change is needed, and applies the fix. Informational comments and false positives are noted and resolved.
4

Commits, pushes, and loops

Commits the fixes, pushes, and goes back to step 1. The loop runs up to 5 iterations to avoid runaway cycles.
5

Exits when clean

Stops when Greptile returns 5/5 confidence with zero unresolved comments, or after the max iterations.

​
Output

On success:
If the loop hits the iteration limit:
