Fix It! Feature - GitHub Token Flow Update

Summary​

Updated the Fix It! feature to use the client-side GitHub token (from Backstage GitHub authentication) for all Git operations instead of relying on Vault. This ensures the same authenticated token used to view repositories is used to create branches.

Changes Made​

1. GitHub Repositories Component​

File: packages/app/src/components/github/GithubRepositories.tsx

Changes:

  • Added githubToken state variable
  • Store token when GitHub client initializes: setGithubToken(accessToken)
  • Pass token to FixItDialog component
const [githubToken, setGithubToken] = useState<string>('');

// In initializeGitHub:
const accessToken = await githubAuthApi.getAccessToken(['repo', 'read:org', 'read:user']);
setGithubToken(accessToken);

// Pass to dialog:
<FixItDialog githubToken={githubToken} {...props} />

2. FixItDialog Component​

File: plugins/claude-flow/src/components/FixItDialog/FixItDialog.tsx

Changes:

  • Added githubToken prop to interface
  • Pass token to API calls for branch operations
  • Include token in navigation state for session creation
export interface FixItDialogProps {
  githubToken: string; // NEW
  // ... other props
}

// Use in API calls:
await claudeFlowApi.getNextBranchName(repository, branch, githubToken);
await claudeFlowApi.createBranch({ ..., githubToken });

// Pass to session creation:
navigate('/claude-flow/create', {
  state: { prContext: { ..., githubToken } }
});

3. API Interface & Client​

File: plugins/claude-flow/src/api/ClaudeFlowApi.ts File: plugins/claude-flow/src/api/ClaudeFlowClient.ts

Changes:

  • Updated method signatures to accept githubToken parameter
  • Pass token in X-GitHub-Token custom header
// Interface:
getNextBranchName(repository: string, baseBranch: string, githubToken: string): Promise<string>;
createBranch(request: { ..., githubToken: string }): Promise<BranchInfo>;

// Client implementation:
headers: {
  'X-GitHub-Token': githubToken,
}

4. Backend Router​

File: plugins/claude-flow-backend/src/router.ts

Changes:

  • Remove vault dependency for branch operations
  • Read token from X-GitHub-Token header instead
  • Pass directly to GitHubService
// OLD:
const githubToken = await vaultSecretsService.getGithubToken(authHeader);

// NEW:
const githubToken = req.headers['x-github-token'] as string;
if (!githubToken) {
  res.status(401).json({ error: 'GitHub token required in X-GitHub-Token header' });
  return;
}

5. Create Session Form​

File: plugins/claude-flow/src/components/CreateSessionForm/CreateSessionForm.tsx

Changes:

  • Updated PRContext interface to include optional githubToken
  • Token available in prContext for future session creation enhancements
interface PRContext {
  repository: string;
  branch: string;
  prNumber: number;
  prTitle: string;
  prUrl: string;
  githubToken?: string; // NEW - available for session creation
}

Token Flow​

User Authentication (Backstage GitHub OAuth)
    ↓
GitHub Repositories Page (stores token)
    ↓
Fix It! Button Click (passes token to dialog)
    ↓
FixItDialog Component (uses token for API calls)
    ↓
API Client (sends token in X-GitHub-Token header)
    ↓
Backend Router (reads from header, no vault lookup)
    ↓
GitHubService (uses token with Octokit)
    ↓
GitHub API (authenticates with user's token)

Benefits​

  1. Consistency: Same token for viewing and modifying repositories
  2. No Vault Dependency: Fix It! operations work without vault configuration
  3. Simpler Architecture: Direct token flow from client to GitHub
  4. Same Permissions: Operations use user's actual GitHub permissions
  5. Better Security: Token only in HTTPS headers, never stored backend
  6. Seamless UX: No additional authentication required

Testing​

Build Status​

✅ Frontend plugin builds successfully ✅ Backend plugin builds successfully ✅ No TypeScript errors ✅ No compilation warnings

Manual Testing Steps​

  1. Navigate to GitHub Repositories page
  2. Verify repositories load (confirms token works)
  3. Click "Fix It!" on any PR
  4. Verify dialog opens with branch name computed
  5. Select "Create new branch" option
  6. Click "Continue to Session Setup"
  7. Verify branch created on GitHub
  8. Verify session form pre-filled with PR context

Security Considerations​

✅ Secure Implementation​

  • Token transmitted via HTTPS only
  • Token in custom header (not URL or body)
  • Token not stored on backend
  • Token not logged
  • Token scoped to user's GitHub permissions

✅ Error Handling​

  • Missing token: Clear error message
  • Invalid token: GitHub API error returned
  • Network errors: Graceful degradation
  • Unauthorized: 401 response with helpful message

Backward Compatibility​

  • ✅ Other Claude Flow features unchanged
  • ✅ Vault still used for regular session operations
  • ✅ No breaking changes to existing APIs
  • ✅ Fix It! feature is additive only

Next Steps (Future Enhancements)​

  1. Use GitHub token for session container operations (if user selects GitHub Token option)
  2. Add token validation before showing Fix It! button
  3. Handle token refresh if expired during operation
  4. Add permission checks (verify write access to repo)
