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. Both skills are open source and available at github.com/greptileai/skills.
Prerequisites:

​
Install

Clone the skills into your Claude Code skills directory. See the Claude Code skills docs for more on how skill discovery works. 
git clone https://github.com/greptileai/skills.git ~/.claude/skills/greptile
Or add as a submodule in your project: 
git submodule add https://github.com/greptileai/skills.git .skills/greptile

​
check-pr

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

​
Usage

/check-pr
Or with a specific PR number: 
/check-pr 42
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:
CategoryMeaning
ActionableCode changes, test improvements, or fixes needed
InformationalVerification notes, questions, or FYIs
Already addressedResolved by subsequent commits
4

Fixes and resolves

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

​
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

/greploop
Or with a specific PR number: 
/greploop 42

​
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: 
Greploop complete.
  Iterations:    2
  Confidence:    5/5
  Resolved:      7 comments
  Remaining:     0
If the loop hits the iteration limit: 
Greploop stopped after 5 iterations.
  Confidence:    4/5
  Resolved:      12 comments
  Remaining:     2

Remaining issues:
  - src/auth.ts:45 — "Consider rate limiting this endpoint"
  - src/db.ts:112 — "Missing index on user_id column"
