magic-slash v0.42.4 - /pr

Follow each step in order. Skipping steps leads to broken PRs, stale Jira tickets, or a desynchronized Desktop UI.

Key steps:

• Step 2: Pre-push validation — catches lint/type errors before they block the push
• Step 3: Push to remote — the PR needs code on the remote
• Step 6: Create the Pull Request — the core deliverable of this skill
• Step 6.4: Update Magic Slash metadata — keeps the Desktop app UI in sync
• Step 7: Update the Jira/GitHub ticket — closes the feedback loop with the team

You are an assistant that finalizes a task by pushing commits, creating a PR and updating the Jira/GitHub ticket.

Configuration

Read ~/.config/magic-slash/config.json once at the start and keep it in memory for the entire workflow.

Determine the parameters based on the current repo:

1. Identify the current repo by comparing $PWD with the paths in .repositories
2. For each parameter, check the repo config
3. If no value is defined, use the default value

Language parameters

Parameter	Repo path	Default
PR language	.repositories.<name>.languages.pullRequest	"en"
Jira language	.repositories.<name>.languages.jiraComment	"en"
Discussion language	.repositories.<name>.languages.discussion	"en"

Branch configuration

Read ~/.config/magic-slash/config.json to determine the development branch:

1. Once the repo is identified, read .repositories.<name>.branches.development
2. If an argument is provided (e.g., /magic:pr develop), use it directly as $DEV_BRANCH and skip confirmation.
3. Otherwise, always confirm with the user using AskUserQuestion:

If a default is configured (e.g., "develop")

Use AskUserQuestion with the text from MSG_BRANCH_CONFIRM (substituting {branch}).

• Empty / short confirmation ("oui", "yes", "ok", "go"): Use the configured default branch
• Another branch name (e.g., "develop", "staging"): Use that branch instead

If no default is configured

Use AskUserQuestion with the text from MSG_BRANCH_ASK.

4. Store the result as $DEV_BRANCH.

Pull Request parameters

Parameter	Repo path	Default	Description
Auto-link tickets	.repositories.<name>.pullRequest.autoLinkTickets	true	Add Jira/GitHub links in the PR

Issues parameters

Parameter	Repo path	Default	Description
Comment on PR	.repositories.<name>.issues.commentOnPR	true	Add a comment with the PR link

Step 0: Check configuration and detect multi-repo worktrees

0.0: Check configuration

Before starting, verify that the Magic Slash configuration exists:

CONFIG_FILE=~/.config/magic-slash/config.json
if [ ! -f "$CONFIG_FILE" ]; then
  # Display MSG_CONFIG_ERROR and stop
fi

If the config does not exist, display MSG_CONFIG_ERROR and stop.

0.1: Extract the ticket ID from the current worktree

Get the current directory name and extract the ticket ID:

basename "$PWD"

The worktree name follows the pattern {repo-name}-{TICKET-ID} (e.g.: my-api-PROJ-123, my-web-PROJ-123).

Extract the TICKET-ID using the pattern and store it as $TICKET_ID:

• Jira: [A-Z]+-\d+ (e.g.: PROJ-123, ABC-456)
• GitHub: the last numeric segment after the repo name (e.g.: 123 in my-api-123)

If no ID is detected from the worktree name, try extracting from the current branch name (e.g., feature/PROJ-123-description → PROJ-123). If still no ID is found, $TICKET_ID remains empty — the user will be asked later (Step 8) if they want to link a ticket.

Skip worktree detection (Steps 0.2–0.4) if you are in a regular repo, not a worktree, and proceed to Step 1.

0.2: Search for associated worktrees

Using the config already loaded in the Configuration step, retrieve the list of configured repos with their paths.

For each configured repo, check if a worktree with the same TICKET-ID exists:

ls -d {REPO_PATH}-{TICKET_ID} 2>/dev/null

For example, if TICKET-ID = PROJ-123 and the repos are /projects/api and /projects/web, search for:

• /projects/api-PROJ-123
• /projects/web-PROJ-123

Collect all found worktrees.

0.3: Check unpushed commits in each worktree

For each found worktree, check if there are commits to push:

git -C {WORKTREE_PATH} log origin/$(git -C {WORKTREE_PATH} branch --show-current)..HEAD --oneline 2>/dev/null

Keep only the worktrees that have unpushed commits.

0.4: Summary and confirmation

If multiple worktrees have commits to push, display MSG_MULTI_REPO_SUMMARY, substituting {TICKET-ID} and the worktree list with commit counts.

If multi-repo detected, execute Steps 1 to 7 for EACH worktree that has commits. Change directory before each cycle:

cd {WORKTREE_PATH}

At the end of each PR, display a confirmation before moving to the next worktree. The Jira/GitHub ticket (Step 7) must be updated ONLY ONCE at the end, with links to ALL created PRs.

Multi-repo partial failure handling

If a worktree fails during its PR cycle (push error, API failure, etc.):

1. Do not stop the entire process — log the failure for this worktree
2. Continue to the next worktree after displaying MSG_MULTI_REPO_FAILURE, substituting {worktree-name} and {error reason}
3. Include failed worktrees in the Step 8 summary with their error status

Step 0.6: Detect and activate Node.js version

Read references/node-setup.md to detect the Node.js version manager and set $NODE_PREFIX.

For multi-repo: Re-execute this step each time you switch to a different worktree, as each repo may require a different Node.js version.

---

Step 1: Get the current branch

git branch --show-current

Verify that you are not on main or master. If so, display MSG_ON_MAIN_BRANCH and stop.

Step 1.1: Check for existing PR

Before pushing and creating a new PR, check if a PR already exists for this branch:

Use mcp__github__list_pull_requests with the head parameter (format: {owner}:{branch}) to search for open PRs matching the current branch.

• If an open PR exists: Use AskUserQuestion with the text from MSG_PR_EXISTS (substituting {number} and {url}). Options:
  1. Stop here (PR already exists)
  2. Continue (push new commits to the existing PR)
• If no PR exists: Proceed to Step 2.

Step 2: Pre-push validation

Before pushing, run a quick validation to catch issues that would cause push hooks to fail.

2.1: Detect the project's verification command

Detect the appropriate validation command for the project:

1. Check package.json scripts for common verification commands:
   • "lint" → npm run lint (or yarn/pnpm equivalent)
   • "typecheck" or "type-check" → npm run typecheck
   • "check" → npm run check
2. For non-Node.js projects, detect common tools:
   • Python: mypy, ruff check, flake8
   • Go: go vet ./...
   • Rust: cargo check
3. If no verification command is found, skip this step

2.2: Run validation

Run the detected command:

# Example for Node.js projects:
$NODE_PREFIX npm run lint

Node.js version: If $NODE_PREFIX was determined in Step 0.6, prepend it to any validation command.

2.3: Handle validation results

• All checks pass: Proceed to Step 3
• Checks fail: Use AskUserQuestion with the text from MSG_PRE_PUSH_VALIDATION (substituting {error output}). Options:
  1. Fix the issues and re-validate (repeat up to 3 times)
  2. Proceed anyway (issues may be caught by push hooks)
  3. Abort

Step 3: Push to remote

Node.js version: If $NODE_PREFIX was determined in Step 0.6, prepend it to the git push command so that pre-push hooks run with the correct Node.js version.

# If $NODE_PREFIX is set (e.g. nvm):
source ~/.nvm/nvm.sh && nvm use && git push -u origin <branch-name>

# If $NODE_PREFIX is empty:
git push -u origin <branch-name>

3.1: Push hook error handling

If the push fails (non-zero exit code), analyze the error:

Error classification by level:

Level	Error type	Examples	Action
1 - Auto	Formatter	Prettier, Black, gofmt	Fix automatically
2 - Semi-auto	Linter	ESLint --fix, Pylint, Flake8, Rubocop	Fix and inform
3 - Manual	Type check	TypeScript, mypy	Ask the user
3 - Manual	Tests	Jest, pytest (if in pre-push)	Ask the user
3 - Manual	Other	Secrets detected, files too large	Ask the user

For level 3 errors (manual)

These errors require human intervention because automatic fixes could introduce regressions.

Use AskUserQuestion with the text from MSG_PUSH_ERROR_MANUAL (substituting {error message}). Options:

1. Fix manually and retry
2. Skip this check (--no-verify) — warn the user if they choose this
3. Abort push

Automatic correction process (levels 1 and 2 only)

1. Analyze the error output to identify:

   • The affected files
   • The problematic lines
   • The error type (lint, format, type, etc.)

2. Fix the code:

   • Read the files with errors
   • Apply the necessary corrections
   • For formatting, run the formatter if available: npx prettier --write, black, etc.
   • Remember to prepend $NODE_PREFIX (from Step 0.6) to any Node.js command (npx, npm, yarn, pnpm)

3. Re-stage and commit the corrected files:

   git add <corrected-files>
   git commit --amend --no-edit
   

4. Retry the push (remember to prepend $NODE_PREFIX if set):

   git push -u origin <branch-name>
   

5. Repeat up to 3 times maximum. If the push still fails after 3 attempts, display a detailed error message and ask the user to intervene.

Display MSG_PUSH_AUTO_FIX during the correction process, substituting the error details and fix results.

Step 4: List commits for the PR

git log origin/$DEV_BRANCH..HEAD --oneline

Retrieve the list of commits that will be included in the PR.

Step 4.1: Understand the changes for the PR description

Always start with the overview to avoid loading a massive diff into context:

git diff origin/$DEV_BRANCH..HEAD --stat

Then selectively read the key files (business logic, API routes, components) to understand the actual changes:

1. From the --stat output, identify key files vs secondary files (tests, config, types, lock files)
2. Read key modified files individually using Read to understand the changes in context
3. Use this understanding to write a meaningful summary and concrete testing instructions in Step 6

Only use git diff origin/$DEV_BRANCH..HEAD for small changes (< 10 files, < 200 lines total). For anything larger, the selective approach above produces better PR descriptions while consuming far less context.

Step 5: Retrieve the project's PR template

Check if a PR template exists in the project:

cat .github/PULL_REQUEST_TEMPLATE.md 2>/dev/null || cat .github/pull_request_template.md 2>/dev/null || cat docs/pull_request_template.md 2>/dev/null || echo ""

If a template exists, you must strictly follow it and fill in its sections. For any section related to testing (e.g., "Testing", "How to test", "Test Steps", "Comment tester", "Vérification"), you must analyze the diff from Step 4.1 to fill it with concrete, specific testing steps based on the actual code changes. Do NOT use generic placeholders.

Step 5.1: Check for conflicts with base branch

Before creating the PR, check if there are merge conflicts with the base branch:

git fetch origin $DEV_BRANCH --quiet
git merge-tree $(git merge-base HEAD origin/$DEV_BRANCH) HEAD origin/$DEV_BRANCH | grep -c "^<<<<<<<" 2>/dev/null || echo "0"

If conflicts are detected, use AskUserQuestion with the text from MSG_CONFLICTS_DETECTED (substituting {base_branch}). Options:

1. Create the PR anyway (resolve conflicts later)
2. Abort and resolve conflicts first

If no conflicts, proceed directly to Step 6.

Step 6: Create the Pull Request via MCP GitHub

This is the core deliverable — without the PR, the entire workflow has no output.

6.0: Resolve the base branch

Use $DEV_BRANCH (resolved from the branch configuration above) as the base branch for the PR.

If $DEV_BRANCH was not resolved earlier (e.g., the branch configuration section was skipped), fall back to dynamic detection:

BASE_BRANCH=$(git remote show origin | grep 'HEAD branch' | cut -d: -f2 | xargs)
if ! git rev-parse --verify origin/$BASE_BRANCH >/dev/null 2>&1; then
  BASE_BRANCH="main"
fi
if ! git rev-parse --verify origin/$BASE_BRANCH >/dev/null 2>&1; then
  BASE_BRANCH="master"
fi

Otherwise, set BASE_BRANCH=$DEV_BRANCH.

6.1: Generate PR title and description

Prepare the PR content:

• Title: Based on the branch name or the first commit
  • If the branch contains a ticket ID (e.g.: feature/PROJ-123), use the format: [PROJ-123] Description
• Description:
  • If a PR template exists: Use it and fill in all its sections
  • Otherwise: Use the default template matching .languages.pullRequest (see MSG_PR_TEMPLATE_EN / MSG_PR_TEMPLATE_FR)
  • Add a "Linked Issues" section with the ticket link (unless autoLinkTickets is false)

CRITICAL — Markdown formatting: The body parameter MUST contain actual line break characters, NOT the two-character literal sequence \n. This is verified automatically in Step 6.2.1.

Linked Issues section (by default, unless autoLinkTickets: false)

Add this section at the end of the PR description.

For Jira tickets: only if integrations.atlassian is true. If false, skip the Jira link — use the ticket ID as plain text without a URL.

For Jira tickets (when Atlassian is enabled), adapt the Jira URL based on the user's domain (retrieved via mcp__atlassian__getAccessibleAtlassianResources):

## Linked Issues

- Jira: [PROJ-123](https://your-domain.atlassian.net/browse/PROJ-123)

For GitHub issues, use the closes keyword for automatic linking:

## Linked Issues

- Closes #123

6.2: Preview and confirm before creation

Use AskUserQuestion with the text from MSG_PR_PREVIEW (substituting {title}, {base_branch}, {head_branch}, and {description_preview} — first 10 lines of the description). Options:

• Y/O or Enter: Proceed with creation
• n: Abort
• edit: Let the user modify the title or description before creation

6.2.1: Verify and fix formatting before creation

After the user confirms, verify the PR body before passing it to the MCP tool. If any check fails, reconstruct the body from scratch and re-verify (max 2 retries).

Checks to perform on the body string:

1. No literal escape sequences: the body must not contain the two-character sequences \n, \t, or \r. These must be actual line break characters. This is the most common failure — it causes GitHub to render the entire PR as a single unreadable paragraph.
2. No unfilled template placeholders: the body must not contain instruction text inside square brackets (e.g., [Concise summary of changes], [List of commits]). Every [instruction] from the template must have been replaced with actual content.
3. Required section headers present: the body must contain at least ## Summary and ## Changes as distinct lines (or their FR equivalents ## Résumé and ## Changements if languages.pullRequest is "fr").
4. Non-empty sections: each section heading must be followed by at least one non-blank line of actual content before the next heading or end of body.

If any check fails:

• Log which check(s) failed
• Reconstruct the body from the commits and diff (re-read if needed)
• Re-verify the reconstructed body
• After 2 failed retries, show the body to the user with AskUserQuestion and ask them to fix it manually

6.3: Create the PR

Use mcp__github__create_pull_request:

• Base: The branch resolved in step 6.0
• Head: The current branch

If the PR creation fails, retry once. If it fails again, display MSG_PR_CREATION_FAILED and ask the user if they want to: (1) Retry, (2) Create the PR manually on GitHub. Display the branch name and base branch to help with manual creation.

Step 6.4: Update Magic Slash metadata

This updates the Magic Slash Desktop UI with the PR link, status, and title. Without it, the user sees stale data in the app. Always run this after creating the PR.

After creating the PR, update the title, status and PR link of the agent:

[ -n "$MAGIC_SLASH_PORT" ] && [ -n "$MAGIC_SLASH_TERMINAL_ID" ] && curl -s "http://127.0.0.1:$MAGIC_SLASH_PORT/metadata?id=$MAGIC_SLASH_TERMINAL_ID&title=$(echo -n '✅ PR #{PR_NUMBER} - {TICKET_ID}' | jq -sRr @uri)&status=PR%20created&prUrl=$(echo -n '{PR_URL}' | jq -sRr @uri)&prRepo=$(echo -n "$PWD" | jq -sRr @uri)" > /dev/null 2>&1 || true

Replace:

• {PR_NUMBER}: The created PR number (e.g.: 42)
• {TICKET_ID}: The ticket ID (e.g.: PROJ-123)
• {PR_URL}: The full PR URL (e.g.: https://github.com/org/repo/pull/42)

This command is silent and never blocks the process.

Step 7: Update the Jira/GitHub ticket

Use $TICKET_ID (extracted in Step 0.1). If $TICKET_ID is empty, use AskUserQuestion to ask the user if they want to link a ticket manually (and which one). If they decline, skip to Step 7.3.

7.0: Check Atlassian integration

Read integrations.atlassian from ~/.config/magic-slash/config.json. Default: true.

If integrations.atlassian is false, skip Step 7.1 entirely (Jira ticket update). Only execute Step 7.2 (GitHub issues).

7.1: Jira tickets (pattern [A-Z]+-\d+)

If a Jira ticket ID is found, use the MCP Atlassian tools:

Note: If you don't know the cloudId, first use mcp__atlassian__getAccessibleAtlassianResources to obtain it.

1. Retrieve available transitions with mcp__atlassian__getTransitionsForJiraIssue
2. Change the status to "To be reviewed" (or equivalent) with mcp__atlassian__transitionJiraIssue
   • If the "To be reviewed" status doesn't exist, try: "In Review", "Code Review", "Review"
3. Add a comment with the PR link via mcp__atlassian__addCommentToJiraIssue (unless commentOnPR is false)
   • Use MSG_JIRA_COMMENT for the comment body

7.2: GitHub issues (numeric pattern #\d+)

If a GitHub issue ID is found:

1. Add a comment on the issue with the PR link via mcp__github__add_issue_comment (unless commentOnPR is false)
   • Use MSG_GITHUB_ISSUE_COMMENT for the comment body
2. Update labels (optional): If the issue has a "todo" or "in progress" label, update it to "in review" if that label exists via mcp__github__update_issue

Note: The closes #123 keyword in the PR description (from Step 6.1) will automatically close the issue when the PR is merged. No need to close it manually here.

Step 7.3: Final summary

Display MSG_SUMMARY, substituting {branch}, {PR_URL}, {PR_NUMBER}, {TICKET_ID}, and {ticket_status}.

Step 8: Multi-repo summary (if applicable)

If you created PRs in multiple worktrees, display MSG_MULTI_REPO_FINAL, substituting {TICKET-ID} and the per-worktree results (each with {worktree-name}, {PR_URL}, and any {error reason} for failed worktrees).
