Accept ctx as the first parameter on the blocking I/O entry points and
propagate it to downstream blocking calls so the work is cancellable from
the process entry point:
- appconfig.Load / LoadWithOptions: honor ctx before the blocking file
reads, returning defaults on a cancelled context.
- LSP: lsp.Server.Run(ctx) ties the serve loop to the caller context via a
new watchParentContext bridge (cancels the server context, aborting
in-flight LLM work). Threaded through hexailsp.Run/RunWithConfig/
RunWithFactory and runtimeconfig.Store.Reload.
- MCP: mcp.Server.Run(ctx) stops accepting requests once ctx is cancelled;
threaded through hexaimcp.Run/RunWithFactory/RunBackfill.
- editor: RunEditor/OpenTempAndEdit/OpenFile take ctx and use
exec.CommandContext so a cancelled context kills the editor subprocess;
threaded through hexaicli, hexaiaction and askcli call sites.
Top-level callers (cmd/hexai-lsp-server, cmd/hexai-mcp-server) now build a
signal-cancelled context (SIGINT/SIGTERM) so shutdown tears the run down
cleanly. Updated comments to explain the cancellation flow and added
cancellation tests for the LSP/MCP loops, editor, and config load.
All tests pass with -race; cross-package coverage 86.2%.

Code quality fixes from audit:
- Log silently discarded errors in status sinks and stats.Update call sites
- Fix json.Marshal errors silently ignored in LSP handlers
- Replace time.Sleep in tests with channel signaling (mcp) and fake clock (stats)
- Make context cancellation work in production time.Sleep sites (handlers_document, cmdentry)
- Remove init()-based provider registration from llm package; use explicit RegisterAllProviders()
- Add WaitGroup goroutine tracking to MCP server Run()

Adds optional syncing of MCP prompts to Markdown slash command files
for AI agents that don't yet support MCP prompts (e.g., Cursor IDE).
Features:
- Syncs prompts on create/update/delete operations
- Configurable via TOML config, environment vars, or CLI flags
- Backfill support with --sync-all flag
- Thread-safe atomic file writes
- Non-fatal sync failures (logged but don't break operations)
- Comprehensive test coverage (81.1% total)
Configuration:
- Config: [mcp] slashcommand_sync = true, slashcommand_dir = "~/.cursor/commands"
- Env: HEXAI_MCP_SLASHCOMMAND_SYNC, HEXAI_MCP_SLASHCOMMAND_DIR
- CLI: --slashcommand-sync, --slashcommand-dir, --sync-all
Fixes config merging bug where project config would reset global MCP settings.

Implements tools/list and tools/call endpoints to expose prompt management
operations (create, update, delete) as callable MCP tools. This enables Claude
to use the meta-prompts (save_prompt, update_prompt) to actually create and
modify prompts.
Key changes:
- Add Tool type definitions (Tool, ListToolsRequest, CallToolRequest, etc.)
- Implement handleToolsList() returning 3 tools with JSON Schemas
- Implement handleToolsCall() with tool wrappers for create/update/delete
- Add 17 comprehensive unit tests (82.8% coverage maintained)
- Update meta-prompts to reference tools instead of JSON-RPC methods
- Enable listChanged notifications for immediate prompt availability
- Refactor large functions into helpers to stay under 50-line limit
Tools advertised alongside Prompts capability. All functions under 50 lines.
Backward compatible - existing prompts/* JSON-RPC methods unchanged.

Two issues prevented Claude Code CLI from discovering MCP prompts:
1. Protocol version mismatch: Server always returned "2025-06-18" but
Claude Code sends "2025-11-25". Per MCP spec, server must echo
back the client's version if supported. Now supports all known
versions (2024-11-05 through 2025-11-25).
2. Null prompts array: Go nil slices marshal as JSON null, but Claude
Code expects an empty array []. Initialize prompts slice with make()
to ensure [] in JSON output.

The MCP stdio protocol uses newline-delimited JSON (JSONL), not LSP-style
Content-Length headers. This was discovered during integration testing with
Claude Code CLI which could not connect to the server.
Also updates docs/mcp-setup.md with correct Claude Code CLI configuration
(use `claude mcp add` instead of editing JSON files) and adds integration
test runbook for testing against real Claude Code CLI instances.

Implements a full Model Context Protocol (MCP) server for managing and serving prompts
to LLM applications. The server provides CRUD operations for prompts with automatic
backups and template rendering support.
Key additions:
- cmd/hexai-mcp-server: Main MCP server binary entrypoint
- internal/hexaimcp: Server orchestrator with configuration and setup
- internal/mcp: Core MCP protocol implementation (JSON-RPC 2.0)
- internal/promptstore: Prompt storage with JSONL backend and automatic backups
- Comprehensive test suites achieving 80%+ coverage for all MCP packages
- Magefile targets for building and installing the MCP server
- Complete documentation for setup, API, prompts, and backups
Test coverage:
- internal/hexaimcp: 84.3%
- internal/mcp: 80.3%
- internal/promptstore: 81.2%
- Overall project: 81.5%
