The server defines 4 tools with complete input schemas and descriptions, but several definition quality issues reduce the score. All tools follow verb_noun naming (create_, upload_, sync_). Schemas are present and mostly well-structured with type definitions and parameter descriptions. However, parameter descriptions lack specificity about constraints, formats, and error recovery guidance. Output schemas are NOT documented anywhere in the provided code, critical gap for downstream tool composition. Error handling exists but responses lack actionable recovery guidance. Security concern: the config file embeds a hardcoded Gitea token in fallback/testing code, violating secret-injection patterns. Tool descriptions are adequate (80-150 chars) but lack 'WHEN to use this instead of another tool' guidance for the four related sync/upload tools.

• Document output schema for all four tools. Define return fields (e.g., repository_id, upload_status, sync_summary) so agents know what data is available for chaining and what the response structure is.
• URGENT: Remove hardcoded token from config/index.ts. Use environment variables (GITEA_INSTANCES) exclusively. Never embed credentials in code, even in fallback/test paths. Audit all other configuration files for exposed secrets.
• Add numeric bounds to maxFileSize parameter (e.g., '1-104857600 bytes'). Add enum or regex pattern to branch parameter (e.g., '^[a-zA-Z0-9._-]+$'). Add min/max to timeout parameters.
• Expand tool descriptions to distinguish responsibilities: 'Use create_repository to initialize a new repo. Use upload_files for one-time file additions. Use sync_project to mirror an entire local directory (respects .gitignore). Use sync_update for targeted modifications with conflict resolution.' Add 10-20 chars per description for clarity.
• Add error recovery guidance to each tool description, e.g.: 'If upload fails with 'branch not found', ensure branch exists or omit branch parameter to use default. Retryable errors: network timeout, rate limit. Non-retryable: invalid authentication, permission denied.'
• For sync_update, add a note: 'Conditional parameters: operation=modify or delete requires sha (auto-detected if omitted). operation=add does not require sha. Omitting required sha when needed will fail with specific error message.'
• Add per-item success/failure response format. When sync_project processes N files, return {uploaded: [], failed: [{path, error}]} instead of all-or-nothing success/fail. Enables agents to retry only failed items.
