📚 Add optimization guide to CLAUDE.md
Problem
A fresh Claude instance using this MCP server doesn't know:
- When to use GraphQL vs REST (91% token difference!)
- That
github_suggest_workflowexists for bulk operations - That
response_format: "compact"saves 80-97% tokens
Solution
Update CLAUDE.md with an Optimization Tips section that gets loaded into every conversation.

Standardize pagination and add compact response format for AI optimization
Summary
Dogfooding audit reveals inconsistent pagination parameters and missing compact output options across 36 tools. This makes tools harder for Claude (the primary AI user) to use effectively and can cause buffer overflow issues with verbose responses.
Problems Identified
| Issue | Count | Impact |
|---|---|---|
Uses per_page instead of limit |
23 tools | Inconsistent API, confusing |
Missing response_format param |
17 tools | Can't get compact output |
| No p |

Consolidate Deno executor: Remove dead mod.ts, keep only mod-pooled.ts
Summary
When connection pooling was added, mod.ts became dead code since USE_CONNECTION_POOL = true by default. We now maintain two nearly identical files, which caused bugs when updating one but not the other (see #32).
Current Architecture
deno_runtime.py
│
├─► if USE_CONNECTION_POOL (default: true)
│ └─► deno_pool.py → mod-pooled.ts ✅ (used 99% of time)
│
└─► else (fallback)
└─► mod.ts ❌ (dead code)
Problem
- Code duplication

Bug: listAvailableTools() exceeds response buffer with 112 tools
Description
listAvailableTools() returns full metadata for all 112 tools, causing the response to exceed the Deno executor's buffer limit.
Error Message
Error reading from process: Separator is not found, and chunk exceed the limit
Root Cause
The current implementation returns full tool objects including:
- name
- description
- parameters (with all details)
- example usage
- required/optional flags
For 112 tools, this creates a massive JSON payload that exceeds the read

✅ [RESOLVED] File tools bug fixed - ETag caching issue
✅ BUG FIXED!
Root Cause Identified:
The new ETag caching in PR #14 was returning {"_from_cache": True} markers, but the file tools weren't handling them.
Fix Applied by Cursor:
- Updated
github_get_file_content(lines 1372-1417) - Updated
github_list_repo_contents(lines 1776-1850) - Both now detect cache markers and make fresh requests
- Added safe
.get()access throughout
Testing Results:
✅ github_get_file_content - WORKING
✅ github_list_repo_contents - WORKING

### 🎯 Phase 2.5: Workspace Architecture for Token Efficiency & User Projects
## 🎯 Vision: Workspace-Based Architecture
### Problem Statement
The current `repo_read_file_chunk` tool (added in PR #14) is **repo-root constrained**, meaning it can only read files within the github-mcp-server repository itself. While this is perfect for meta-dogfooding during development, it's **not useful for actual customers** who will be using the MCP server to work on their own projects.
**Current limitation:**
- ✅ Works for: developers working on github-mcp-server itself
- ❌ Doesn't w
