Action items

Generated: 2025-12-31

This document catalogues all TODOs, FIXMEs, stubs, and incomplete implementations found in the Pattern codebase. Items are organized by severity and then by crate.

Design decisions to revisit

Location Issue
pattern_core/src/context/builder.rs:944 Panics on non-Text content - may need graceful handling
pattern_macros/src/lib.rs:1169,1186 Panics on unknown table names - no fallback
pattern_core/src/memory/store.rs MemoryStore trait has many convenience methods (append_to_block, replace_in_block, etc.) that may be redundant now that StructuredDocument has a richer interface (import_from_json, export_for_editing, etc.). Consider consolidating - callers can use get_block() + document methods + mark_dirty()/persist_block() directly.

Stub modules (intentionally incomplete)

These are known stubs that are explicitly documented:

Module Status Notes
pattern_mcp/src/server.rs STUB Server functionality not implemented
pattern_mcp/src/client/tool_wrapper.rs STUB MCP tool wrapper placeholder
pattern_mcp/src/client/service.rs STUB Simplified stub with mock tool creation
pattern_cli/src/agent_ops.rs PARTIAL STUB Data source registration pending rework
pattern_cli/src/background_tasks.rs STUB Disabled during migration
pattern_core/CLAUDE.md:121 STUB Ollama provider

Critical (blocking core functionality)

pattern_core

Location Issue
src/runtime/context.rs:1493 Graceful shutdown not implemented - uses abort(), in-flight messages may be lost. Needs cancellation tokens.
src/memory/cache.rs:1284 Memory edit operation incomplete - DONE: CRDT-aware replace implemented

pattern_mcp - lower priority than anything in core or cli crate

Location Issue
src/server.rs:110 todo!("Implement MCP server start")
src/server.rs:116 todo!("Implement MCP server stop")

pattern_server - lower priority than anything in core or cli crate

Location Issue
src/lib.rs:32 CORS is permissive - needs proper configuration for production
src/handlers/auth.rs:79 API key authentication not implemented
src/handlers/auth.rs:105 Token family revocation check not implemented
src/handlers/auth.rs:136-138 User loading from database - returns hardcoded "TODO" username

Documentation TODOs

Plan documents in docs/plans/ contain many TODOs, but these are implementation notes for future work rather than incomplete code. They are not included in this list.
