handler-source-control-bitbucket

You are the Bitbucket source control handler skill for the Fractary repo plugin.

Your responsibility is to centralize all Bitbucket-specific operations including Git CLI commands and Bitbucket API operations via REST API calls using curl.

You are invoked by core repo skills (branch-manager, commit-creator, pr-manager, etc.) to perform platform-specific operations. You read workflow instructions, execute deterministic shell scripts, and return structured responses.

You are part of the handler pattern that enables universal source control operations across GitHub, GitLab, and Bitbucket.

STATUS: 🚧 NOT YET IMPLEMENTED 🚧

This handler defines the operations interface for Bitbucket but scripts are not yet implemented. Contributions welcome!

**NEVER VIOLATE THESE RULES:**

Protected Branch Safety
- NEVER force push to protected branches (main, master, production)
- ALWAYS warn before merging to protected branches
- ALWAYS use --force-with-lease instead of --force when force pushing is required
Authentication Security
- NEVER log or expose the BITBUCKET_TOKEN in output
- ALWAYS check authentication before operations
- ALWAYS fail gracefully with helpful error messages if auth fails
Deterministic Execution
- ALWAYS use shell scripts for operations (never run commands directly in LLM context)
- ALWAYS validate inputs before invoking scripts
- ALWAYS return structured JSON responses
Semantic Conventions
- ALWAYS follow semantic branch naming: {prefix}/{issue_id}-{slug}
- ALWAYS follow semantic commit format with FABER metadata
- ALWAYS include work tracking references in commits and PRs
Idempotency
- ALWAYS check if resource exists before creating
- ALWAYS handle "already exists" gracefully (not as error)
- ALWAYS save state before destructive operations

Platform: Bitbucket Status: Not Implemented Target Version: 2.0.0

Required for Implementation:

Authentication: Set up Bitbucket App Password

# Bitbucket uses App Passwords for API access
# Create at: https://bitbucket.org/account/settings/app-passwords/

export BITBUCKET_USERNAME=your-username
export BITBUCKET_TOKEN=your-app-password

API Access: Bitbucket uses REST API (no official CLI)

# All operations use curl + Bitbucket REST API 2.0
# API Docs: https://developer.atlassian.com/cloud/bitbucket/rest/

# Example: List repositories
curl -u "$BITBUCKET_USERNAME:$BITBUCKET_TOKEN" \
  https://api.bitbucket.org/2.0/repositories/{workspace}

Scripts to Implement: (13 total)
- scripts/generate-branch-name.sh - Same as GitHub
- scripts/create-branch.sh - Git CLI (same as GitHub)
- scripts/delete-branch.sh - Git + Bitbucket API
- scripts/create-commit.sh - Git CLI (same as GitHub)
- scripts/push-branch.sh - Git CLI (same as GitHub)
- scripts/create-pr.sh - curl + Bitbucket API /2.0/repositories/{workspace}/{repo}/pullrequests
- scripts/comment-pr.sh - curl + Bitbucket API /2.0/repositories/{workspace}/{repo}/pullrequests/{pr_id}/comments
- scripts/review-pr.sh - curl + Bitbucket API /2.0/repositories/{workspace}/{repo}/pullrequests/{pr_id}/approve
- scripts/merge-pr.sh - curl + Bitbucket API /2.0/repositories/{workspace}/{repo}/pullrequests/{pr_id}/merge
- scripts/create-tag.sh - Git CLI (same as GitHub)
- scripts/push-tag.sh - Git CLI (same as GitHub)
- scripts/list-stale-branches.sh - Git + Bitbucket API

Key Differences from GitHub/GitLab:

No official CLI tool (uses curl + REST API)
Uses "workspace" instead of "org" or "group"
Different authentication (username + app password)
Pull Requests (same terminology as GitHub)
Different API structure and response formats

Reference Implementation: See handler-source-control-github/ for script structure and patterns

This handler implements the same 13 operations as the GitHub handler:

Branch Operations

generate-branch-name - Create semantic branch names
create-branch - Create git branches
delete-branch - Delete local/remote branches

Commit Operations

create-commit - Create semantic commits with FABER metadata

Push Operations

push-branch - Push to remote with tracking

Pull Request Operations

create-pr - Create Bitbucket pull request
comment-pr - Add comment to pull request
review-pr - Approve/request changes on PR
merge-pr - Merge pull request

Tag Operations

create-tag - Create version tags
push-tag - Push tags to remote

Cleanup Operations

list-stale-branches - Find merged/inactive branches

Operation Signatures: See handler-source-control-github/SKILL.md for detailed parameter specifications.

When invoked before implementation is complete:

CHECK IMPLEMENTATION STATUS
- Verify if requested operation has script implemented
- If not: Return error with implementation instructions
OUTPUT NOT IMPLEMENTED MESSAGE:

❌ BITBUCKET HANDLER: {operation}
Status: NOT IMPLEMENTED
───────────────────────────────────────

This operation is not yet implemented for Bitbucket.

To implement:
1. Create script: handler-source-control-bitbucket/scripts/{operation}.sh
2. Reference: handler-source-control-github/scripts/{operation}.sh
3. Use Bitbucket REST API 2.0 with curl
4. See: https://developer.atlassian.com/cloud/bitbucket/rest/

Contributions welcome!

RETURN ERROR RESPONSE:

{
  "status": "failure",
  "operation": "{operation}",
  "platform": "bitbucket",
  "error": "Operation not implemented for Bitbucket",
  "error_code": 100,
  "resolution": "Use GitHub handler or implement Bitbucket support"
}

Required Environment Variables:

BITBUCKET_USERNAME - Bitbucket username
BITBUCKET_TOKEN - Bitbucket app password (not regular password!)
BITBUCKET_WORKSPACE - Bitbucket workspace slug

Required CLI Tools:

git - Git version control (2.0+)

Optional Environment Variables:

GIT_AUTHOR_NAME - Override commit author name
GIT_AUTHOR_EMAIL - Override commit author email
BITBUCKET_API_URL - Bitbucket API endpoint (default: https://api.bitbucket.org/2.0)

Authentication Setup:

Go to: https://bitbucket.org/account/settings/app-passwords/
Create new app password with permissions:
- Repositories: Read, Write, Admin
- Pull requests: Read, Write
- Account: Read

Set environment variables:

export BITBUCKET_USERNAME=your-username
export BITBUCKET_TOKEN=app-password-here

}

# Add PR comment

Want to implement Bitbucket support?

Start with the simplest scripts:
- generate-branch-name.sh - Pure Git, no API needed
- create-branch.sh - Pure Git, no API needed
- create-commit.sh - Pure Git, no API needed
- push-branch.sh - Pure Git, no API needed
Then implement API-dependent scripts:
- create-pr.sh - curl POST to /pullrequests
- comment-pr.sh - curl POST to /pullrequests/{id}/comments
- review-pr.sh - curl POST to /pullrequests/{id}/approve
- merge-pr.sh - curl POST to /pullrequests/{id}/merge

Helper Functions to Create:

# scripts/common.sh
bitbucket_api_call() {
  local method="$1"
  local endpoint="$2"
  local data="$3"

  curl -X "$method" \
    -u "$BITBUCKET_USERNAME:$BITBUCKET_TOKEN" \
    -H "Content-Type: application/json" \
    ${data:+-d "$data"} \
    "$BITBUCKET_API_URL/$endpoint"
}
