Handle incoming tool execution requests from MCP clients.
This is the main request dispatcher that routes tool calls to their
appropriate handlers. It supports both AI-powered tools (from TOOLS registry)
and utility tools (implemented as static functions).
This is the main request dispatcher that routes tool calls to their appropriate handlers.
It supports both AI-powered tools (from TOOLS registry) and utility tools (implemented as
static functions).
Thread Context Reconstruction:
If the request contains a continuation_id, this function reconstructs
the conversation history and injects it into the tool's context.
CONVERSATION LIFECYCLE MANAGEMENT:
This function serves as the central orchestrator for multi-turn AI-to-AI conversations:
1. THREAD RESUMPTION: When continuation_id is present, it reconstructs complete conversation
context from Redis including conversation history and file references
2. CROSS-TOOL CONTINUATION: Enables seamless handoffs between different tools (analyze →
codereview → debug) while preserving full conversation context and file references
3. CONTEXT INJECTION: Reconstructed conversation history is embedded into tool prompts
using the dual prioritization strategy:
- Files: Newest-first prioritization (recent file versions take precedence)
- Turns: Newest-first collection for token efficiency, chronological presentation for LLM
4. FOLLOW-UP GENERATION: After tool execution, generates continuation offers for ongoing
AI-to-AI collaboration with natural language instructions
STATELESS TO STATEFUL BRIDGE:
The MCP protocol is inherently stateless, but this function bridges the gap by:
- Loading persistent conversation state from Redis
- Reconstructing full multi-turn context for tool execution
- Enabling tools to access previous exchanges and file references
- Supporting conversation chains across different tool types
Args:
name: The name of the tool to execute
arguments: Dictionary of arguments to pass to the tool
name: The name of the tool to execute (e.g., "analyze", "chat", "codereview")
arguments: Dictionary of arguments to pass to the tool, potentially including:
- continuation_id: UUID for conversation thread resumption
- files: File paths for analysis (subject to deduplication)
- prompt: User request or follow-up question
- model: Specific AI model to use (optional)
Returns:
List of TextContent objects containing the tool's response
List of TextContent objects containing:
- Tool's primary response with analysis/results
- Continuation offers for follow-up conversations (when applicable)
- Structured JSON responses with status and content
Raises:
ValueError: If continuation_id is invalid or conversation thread not found
Exception: For tool-specific errors or execution failures
Example Conversation Flow:
1. Claude calls analyze tool with files → creates new thread
2. Thread ID returned in continuation offer
3. Claude continues with codereview tool + continuation_id → full context preserved
4. Multiple tools can collaborate using same thread ID

"""
Reconstruct conversation context for thread continuation.
Reconstruct conversation context for stateless-to-stateful thread continuation.
This function loads the conversation history from Redis and integrates it
into the request arguments to provide full context to the tool.
This is a critical function that transforms the inherently stateless MCP protocol into
stateful multi-turn conversations. It loads persistent conversation state from Redis
and rebuilds complete conversation context using the sophisticated dual prioritization
strategy implemented in the conversation memory system.
CONTEXT RECONSTRUCTION PROCESS:
1. THREAD RETRIEVAL: Loads complete ThreadContext from Redis using continuation_id
- Includes all conversation turns with tool attribution
- Preserves file references and cross-tool context
- Handles conversation chains across multiple linked threads
2. CONVERSATION HISTORY BUILDING: Uses build_conversation_history() to create
comprehensive context with intelligent prioritization:
FILE PRIORITIZATION (Newest-First Throughout):
- When same file appears in multiple turns, newest reference wins
- File embedding prioritizes recent versions, excludes older duplicates
- Token budget management ensures most relevant files are preserved
CONVERSATION TURN PRIORITIZATION (Dual Strategy):
- Collection Phase: Processes turns newest-to-oldest for token efficiency
- Presentation Phase: Presents turns chronologically for LLM understanding
- Ensures recent context is preserved when token budget is constrained
3. CONTEXT INJECTION: Embeds reconstructed history into tool request arguments
- Conversation history becomes part of the tool's prompt context
- Files referenced in previous turns are accessible to current tool
- Cross-tool knowledge transfer is seamless and comprehensive
4. TOKEN BUDGET MANAGEMENT: Applies model-specific token allocation
- Balances conversation history vs. file content vs. response space
- Gracefully handles token limits with intelligent exclusion strategies
- Preserves most contextually relevant information within constraints
CROSS-TOOL CONTINUATION SUPPORT:
This function enables seamless handoffs between different tools:
- Analyze tool → Debug tool: Full file context and analysis preserved
- Chat tool → CodeReview tool: Conversation context maintained
- Any tool → Any tool: Complete cross-tool knowledge transfer
ERROR HANDLING & RECOVERY:
- Thread expiration: Provides clear instructions for conversation restart
- Redis unavailability: Graceful degradation with error messaging
- Invalid continuation_id: Security validation and user-friendly errors
Args:
arguments: Original request arguments containing continuation_id
arguments: Original request arguments dictionary containing:
- continuation_id (required): UUID of conversation thread to resume
- Other tool-specific arguments that will be preserved
Returns:
Modified arguments with conversation history injected
dict[str, Any]: Enhanced arguments dictionary with conversation context:
- Original arguments preserved
- Conversation history embedded in appropriate format for tool consumption
- File context from previous turns made accessible
- Cross-tool knowledge transfer enabled
Raises:
ValueError: When continuation_id is invalid, thread not found, or expired
Includes user-friendly recovery instructions
Performance Characteristics:
- O(1) thread lookup in Redis
- O(n) conversation history reconstruction where n = number of turns
- Intelligent token budgeting prevents context window overflow
- Optimized file deduplication minimizes redundant content
Example Usage Flow:
1. Claude: "Continue analyzing the security issues" + continuation_id
2. reconstruct_thread_context() loads previous analyze conversation
3. Debug tool receives full context including previous file analysis
4. Debug tool can reference specific findings from analyze tool
5. Natural cross-tool collaboration without context loss

CONVERSATION-AWARE FILE PROCESSING:

1. FILE DEDUPLICATION WITH NEWEST-FIRST PRIORITY:
- When same file appears in multiple conversation turns, newest reference wins
- Prevents redundant file embedding while preserving most recent file state
- Cross-tool file tracking ensures consistent behavior across analyze → codereview → debug
2. CONVERSATION CONTEXT INTEGRATION:
- All tools receive enhanced prompts with conversation history via reconstruct_thread_context()
- File references from previous turns are preserved and accessible
- Cross-tool knowledge transfer maintains full context without manual file re-specification
3. TOKEN-AWARE FILE EMBEDDING:
- Respects model-specific token allocation budgets from ModelContext
- Prioritizes conversation history, then newest files, then remaining content
- Graceful degradation when token limits are approached
4. STATELESS-TO-STATEFUL BRIDGING:
- Tools operate on stateless MCP requests but access full conversation state
- Conversation memory automatically injected via continuation_id parameter
- Enables natural AI-to-AI collaboration across tool boundaries

Centralized file processing for tool prompts.
Centralized file processing implementing dual prioritization strategy.
This method handles the common pattern across all tools:
1. Filter out files already embedded in conversation history
2. Read content of only new files
3. Generate informative note about skipped files
DUAL PRIORITIZATION STRATEGY CORE IMPLEMENTATION:
This method is the heart of conversation-aware file processing across all tools:
1. CONVERSATION-AWARE FILE DEDUPLICATION:
- Automatically detects and filters files already embedded in conversation history
- Implements newest-first prioritization: when same file appears in multiple turns,
only the newest reference is preserved to avoid redundant content
- Cross-tool file tracking ensures consistent behavior across tool boundaries
2. TOKEN-BUDGET OPTIMIZATION:
- Respects remaining token budget from conversation context reconstruction
- Prioritizes conversation history + newest file versions within constraints
- Graceful degradation when token limits approached (newest files preserved first)
- Model-specific token allocation ensures optimal context window utilization
3. CROSS-TOOL CONTINUATION SUPPORT:
- File references persist across different tools (analyze → codereview → debug)
- Previous tool file embeddings are tracked and excluded from new embeddings
- Maintains complete file context without manual re-specification
PROCESSING WORKFLOW:
1. Filter out files already embedded in conversation history using newest-first priority
2. Read content of only new files within remaining token budget
3. Generate informative notes about skipped files for user transparency

DUAL PRIORITIZATION STRATEGY (Files & Conversations):
The conversation memory system implements sophisticated prioritization for both files and
conversation turns, using a consistent "newest-first" approach during collection but
presenting information in the optimal format for LLM consumption:
FILE PRIORITIZATION (Newest-First Throughout):
1. When collecting files across conversation turns, the system walks BACKWARDS through
turns (newest to oldest) and builds a unique file list
2. If the same file path appears in multiple turns, only the reference from the
NEWEST turn is kept in the final list
3. This "newest-first" ordering is preserved throughout the entire pipeline:
- get_conversation_file_list() establishes the order
- build_conversation_history() maintains it during token budgeting
- When token limits are hit, OLDER files are excluded first
4. This strategy works across conversation chains - files from newer turns in ANY
thread take precedence over files from older turns in ANY thread
CONVERSATION TURN PRIORITIZATION (Newest-First Collection, Chronological Presentation):
1. COLLECTION PHASE: Processes turns newest-to-oldest to prioritize recent context
- When token budget is tight, OLDER turns are excluded first
- Ensures most contextually relevant recent exchanges are preserved
2. PRESENTATION PHASE: Reverses collected turns to chronological order (oldest-first)
- LLM sees natural conversation flow: "Turn 1 → Turn 2 → Turn 3..."
- Maintains proper sequential understanding while preserving recency prioritization
This dual approach ensures optimal context preservation (newest-first) with natural
conversation flow (chronological) for maximum LLM comprehension and relevance.

Get all unique files referenced across all turns in a conversation.
Extract all unique files from conversation turns with newest-first prioritization.
This function extracts and deduplicates file references from all conversation
turns to enable efficient file embedding - files are read once and shared
across all turns rather than being embedded multiple times.
This function implements the core file prioritization logic used throughout the
conversation memory system. It walks backwards through conversation turns
(from newest to oldest) and collects unique file references, ensuring that
when the same file appears in multiple turns, the reference from the NEWEST
turn takes precedence.
PRIORITIZATION ALGORITHM:
1. Iterate through turns in REVERSE order (index len-1 down to 0)
2. For each turn, process files in the order they appear in turn.files
3. Add file to result list only if not already seen (newest reference wins)
4. Skip duplicate files that were already added from newer turns
This ensures that:
- Files from newer conversation turns appear first in the result
- When the same file is referenced multiple times, only the newest reference is kept
- The order reflects the most recent conversation context
Example:
Turn 1: files = ["main.py", "utils.py"]
Turn 2: files = ["test.py"]
Turn 3: files = ["main.py", "config.py"] # main.py appears again
Result: ["main.py", "config.py", "test.py", "utils.py"]
(main.py from Turn 3 takes precedence over Turn 1)

"""
Build formatted conversation history for tool prompts with embedded file contents.
Creates a formatted string representation of the conversation history that includes
full file contents from all referenced files. Files are embedded only ONCE at the
start, even if referenced in multiple turns, to prevent duplication and optimize
token usage.
Creates a comprehensive conversation history that includes both conversation turns and
file contents, with intelligent prioritization to maximize relevant context within
token limits. This function enables stateless tools to access complete conversation
context from previous interactions, including cross-tool continuations.
If the thread has a parent chain, this function traverses the entire chain to
include the complete conversation history.
FILE PRIORITIZATION BEHAVIOR:
Files from newer conversation turns are prioritized over files from older turns.
When the same file appears in multiple turns, the reference from the NEWEST turn
takes precedence. This ensures the most recent file context is preserved when
token limits require file exclusions.
CONVERSATION CHAIN HANDLING:
If the thread has a parent_thread_id, this function traverses the entire chain
to include complete conversation history across multiple linked threads. File
prioritization works across the entire chain, not just the current thread.
CONVERSATION TURN ORDERING STRATEGY:
The function employs a sophisticated two-phase approach for optimal token utilization:
PHASE 1 - COLLECTION (Newest-First for Token Budget):
- Processes conversation turns in REVERSE chronological order (newest to oldest)
- Prioritizes recent turns within token constraints
- If token budget is exceeded, OLDER turns are excluded first
- Ensures the most contextually relevant recent exchanges are preserved
PHASE 2 - PRESENTATION (Chronological for LLM Understanding):
- Reverses the collected turns back to chronological order (oldest to newest)
- Presents conversation flow naturally for LLM comprehension
- Maintains "--- Turn 1, Turn 2, Turn 3..." sequential numbering
- Enables LLM to follow conversation progression logically
This approach balances recency prioritization with natural conversation flow.
TOKEN MANAGEMENT:
- Uses model-specific token allocation (file_tokens + history_tokens)
- Files are embedded ONCE at the start to prevent duplication
- Turn collection prioritizes newest-first, presentation shows chronologically
- Stops adding turns when token budget would be exceeded
- Gracefully handles token limits with informative notes
Args:
context: ThreadContext containing the complete conversation
model_context: ModelContext for token allocation (optional, uses DEFAULT_MODEL if not provided)
read_files_func: Optional function to read files (for testing)
context: ThreadContext containing the conversation to format
model_context: ModelContext for token allocation (optional, uses DEFAULT_MODEL fallback)
read_files_func: Optional function to read files (primarily for testing)
Returns:
tuple[str, int]: (formatted_conversation_history, total_tokens_used)
Returns ("", 0) if no conversation turns exist
Returns ("", 0) if no conversation turns exist in the context
Format:
- Header with thread metadata and turn count
- All referenced files embedded once with full contents
- Each turn shows: role, tool used, which files were used, content
- Clear delimiters for AI parsing
- Continuation instruction at end
Output Format:
=== CONVERSATION HISTORY (CONTINUATION) ===
Thread: <thread_id>
Tool: <original_tool_name>
Turn <current>/<max_allowed>
You are continuing this conversation thread from where it left off.
Note:
This formatted history allows tools to "see" both conversation context AND
file contents from previous tools, enabling true cross-tool collaboration
while preventing duplicate file embeddings.
=== FILES REFERENCED IN THIS CONVERSATION ===
The following files have been shared and analyzed during our conversation.
[NOTE: X files omitted due to size constraints]
Refer to these when analyzing the context and requests below:
<embedded_file_contents_with_line_numbers>
=== END REFERENCED FILES ===
Previous conversation turns:
--- Turn 1 (Claude) ---
Files used in this turn: file1.py, file2.py
<turn_content>
--- Turn 2 (Gemini using analyze via google/gemini-2.5-flash) ---
Files used in this turn: file3.py
<turn_content>
=== END CONVERSATION HISTORY ===
IMPORTANT: You are continuing an existing conversation thread...
This is turn X of the conversation - use the conversation history above...
Cross-Tool Collaboration:
This formatted history allows any tool to "see" both conversation context AND
file contents from previous tools, enabling seamless handoffs between analyze,
codereview, debug, chat, and other tools while maintaining complete context.
Performance Characteristics:
- O(n) file collection with newest-first prioritization
- Intelligent token budgeting prevents context window overflow
- Redis-based persistence with automatic TTL management
- Graceful degradation when files are inaccessible or too large
