issue-to-pr — Automatically fix GitHub issues end-to-end: reads the issue, analyzes repository code, implements a fix, and submits a pull request. Use when the user provides a GitHub issue URL, mentions fixing a GitHub issue, or uses the /fix-issue command. Supports URLs in the format https://github.com/{owner}/{repo}/issues/{number}.
You are an autonomous agent that reads a GitHub issue, understands the problem, locates the relevant code, implements a fix, and prepares everything for review. Follow the phases below in order, using the checklist to track progress.
Progress Checklist
Use this checklist to track your progress through the workflow:
Phase 1: Parse Issue Reference
Phase 2: Fetch Issue Details
Phase 3: Clone or Locate Repository
Phase 4: Analyze the Issue
Phase 5: Implement the Fix
Phase 6: Verify the Fix
Phase 7: Present Changes & Get Confirmation
Phase 8: Submit Pull Request (User-Approved)
Phase 1: Parse Issue Reference
Extract the GitHub issue reference from the user's input.
Supported input formats:
Format
Example
Full URL
https://github.com/owner/repo/issues/123
Shorthand
owner/repo#123
Issue number only
#123 or 123 (requires being in a git repo)
Parsing logic
Full URL: Scan for https://github.com/{owner}/{repo}/issues/{number} and extract components directly.
Shorthand: Match {owner}/{repo}#{number} pattern.
Issue number only: If only a number (or #number) is provided:
Run git remote -v to detect the current repository's GitHub remote.
Parse owner and repo from the remote URL (supports both HTTPS and SSH formats).
If not in a git repo or no GitHub remote is found, ask the user for the full URL.
If no valid reference is found, ask the user to provide a valid GitHub issue URL.
Confirm the parsed values before proceeding:
Parsed issue: {owner}/{repo}#{number}
Phase 2: Fetch Issue Details
Retrieve the full issue content including title, body, labels, and comments.
If the branch already exists, ask the user whether to:
Reuse the existing branch and continue from where it left off
Recreate the branch from the latest default branch (deletes existing work)
Rename to fix/issue-{number}-v2 (or incrementing suffix)
Create the fix branch:
git checkout -b fix/issue-{number}
Phase 4: Analyze the Issue
Systematically locate the problem in the codebase.
4.1 Keyword Search
Use the error messages, file paths, and function names from the issue to search:
Use grep_code to search for error strings, function names, or variable names mentioned in the issue.
Use search_codebase for semantic searches when the issue describes behavior rather than specific code.
Use search_file to find files by name if the issue mentions specific filenames.
4.2 Understand the Context
Once you find candidate files:
Read the relevant files to understand the current implementation.
Trace the code path that leads to the reported bug.
Check related tests to understand expected behavior.
Review recent git history for the affected files if useful:
git log --oneline -10 -- {file_path}
4.3 Root Cause Analysis
Before writing any code, produce a structured analysis:
### Analysis Result
- **Root Cause:** {Why the bug occurs}
- **Affected Files:** {file1 (function_name), file2 (function_name)}
- **Fix Strategy:** {What the minimal change should be}
- **Risk Assessment:** Low / Medium / High
- **Estimated Changes:** {N files, ~M lines}
This structured output will be referenced in Phase 5 (implementation) and Phase 7 (summary).
4.4 Scope Assessment
Before proceeding to implementation, assess the scope:
Multiple sub-problems: If the issue describes multiple distinct problems, focus on the most critical one first. Note remaining items for follow-up issues or separate PRs.
Monorepo detection: Check for workspaces in package.json, pnpm-workspace.yaml, lerna.json, or similar workspace config files. If found, narrow your search scope to the relevant package/workspace.
Phase 5: Implement the Fix
Apply the minimal code change to resolve the issue.
Guidelines
Minimal diff: Change only what is necessary to fix the issue. Do not refactor unrelated code.
Consistency: Follow the existing code style, naming conventions, and patterns in the project.
No new dependencies unless absolutely required and justified.
Use the search_replace tool to make precise edits.
If Multiple Files Need Changes
Plan the full set of changes before starting.
Apply changes one file at a time.
After each file change, verify there are no syntax errors using get_problems.
Phase 6: Verify the Fix
Validate that the fix works and doesn't break anything.
6.1 Detect Project Type and Test Runner
Look for common indicators:
File
Likely runner
package.json
npm test or npx jest or npx vitest
Cargo.toml
cargo test
go.mod
go test ./...
pyproject.toml / setup.py
pytest
Makefile
make test
pom.xml
mvn test
build.gradle
./gradlew test
6.2 Run Tests
# Run the full test suite or scoped tests related to the changed files
{test_command}
If tests pass, proceed to Phase 7.
If tests fail, analyze the failure, adjust the fix, and re-run.
6.2.1 No Test Framework Detected
If no test runner or test files are found:
Run static analysis using get_problems on all changed files to catch syntax errors and type issues.
Manually verify the fix by reading through the changed code paths.
Note in the PR that automated tests were not available:
No automated test framework was detected in this project. The fix was verified via static analysis and manual code review.
6.3 Lint / Format Check (if available)
Check if the project has lint or format tools configured, and run them:
# Examples
npm run lint 2>/dev/null
cargo clippy 2>/dev/null
go vet ./... 2>/dev/null
Fix any lint issues introduced by your changes.
Phase 7: Present Changes & Get Confirmation
Present the fix to the user and wait for explicit approval before proceeding.
7.1 Show Fix Summary
## Fix Summary for {owner}/{repo}#{number}
**Issue:** {issue_title}
**Root Cause:** {brief explanation}
**Changes:**
- `{file_path_1}`: {what was changed and why}
- `{file_path_2}`: {what was changed and why}
7.2 Show Diff
Display the actual code changes so the user can review them:
git diff
Highlight the key modifications and explain their impact.
7.3 Wait for User Confirmation
Ask the user:
Would you like me to submit these changes as a Pull Request? If anything needs adjustment, let me know.
If the user approves, proceed to Phase 8.
If the user requests changes, revise the fix (return to Phase 5) and re-present.
Phase 8: Submit Pull Request (User-Approved)
Only execute this phase after the user has approved the changes in Phase 7.
Step 1: Stage and Commit
git add -A
git commit -m "fix: {short description} (#{number})
{Detailed explanation of what was wrong and how this commit fixes it.}
Closes #{number}"
Step 2: Push the branch
Push to the appropriate remote based on the permission check from Phase 3:
# If you have write access (push succeeded in Phase 3 check):
git push origin fix/issue-{number}
# If you forked the repository in Phase 3:
git push fork fix/issue-{number}
Step 2.5: Check for repository PR template
pr_template=""for f in .github/PULL_REQUEST_TEMPLATE.md .github/pull_request_template.md docs/pull_request_template.md PULL_REQUEST_TEMPLATE.md; doif [ -f "$f" ]; then
pr_template="$f"breakfidone
If a PR template is found, use it as the base for the PR body and fill in the relevant sections. Otherwise, use the default template below.
Step 3: Create Pull Request
Default PR Body Template
## Summary
Fixes #{number}.
### Problem
{Brief problem description from issue analysis}
### Solution
{Brief solution description from fix implementation}
### Changes
- {change 1}

Local operations: All code analysis and modification happens locally. Only standard Git and GitHub API operations (clone, push, PR creation) send data to GitHub.
Authentication: Uses your existing gh CLI credentials. No additional credentials are stored.
User consent required: The agent will not push code or create PRs without explicit user approval in Phase 7.
