## [Unreleased]
## [0.5.0] - 2026-01-15
### Added
- **Cost Tracking System** - Track LLM API costs across sessions
- New `:CoderCost` command opens cost estimation floating window
- Session costs tracked in real-time
- All-time costs persisted in `.coder/cost_history.json`
- Per-model breakdown with token counts
- Pricing database for 50+ models (GPT-4/5, Claude, O-series, Gemini)
- Window keymaps: `q` close, `r` refresh, `c` clear session, `C` clear all
- **Automatic Ollama Fallback** - Graceful degradation when API limits hit
- Automatically switches to Ollama when Copilot rate limits exceeded
- Detects local Ollama availability before fallback
- Notifies user of provider switch
- **Enhanced Error Handling** - Better error messages for API failures
- Shows actual API response on parse errors (not generic "failed to parse")
- Improved rate limit detection and messaging
- Sanitized newlines in error notifications to prevent UI crashes
- **Agent Tools System Improvements**
- New `to_openai_format()` and `to_claude_format()` functions
- `get_definitions()` for generic tool access
- Fixed tool call argument serialization (JSON strings vs tables)
- **Credentials Management System** - Store API keys outside of config files
- New `:CoderAddApiKey` command for interactive credential setup
- `:CoderRemoveApiKey` to remove stored credentials
- `:CoderCredentials` to view credential status
- `:CoderSwitchProvider` to switch active LLM provider
- Credentials stored in `~/.local/share/nvim/codetyper/configuration.json`
- Priority: stored credentials > config > environment variables
- Supports all providers: Claude, OpenAI, Gemini, Copilot, Ollama
### Changed
- Cost window now shows both session and all-time statistics
- Improved agent prompt templates with correct tool names
- Better error context in LLM provider responses
### Fixed
- Fixed "Failed to parse Copilot response" error showing instead of actual error
- Fixed `nvim_buf_set_lines` crash from newlines in error messages
- Fixed `tools.definitions` nil error in agent initialization
- Fixed tool name mismatch in agent prompts (write_file vs write)
---
## [0.4.0] - 2026-01-13
### Added
- **Event-Driven Architecture** - Complete rewrite of prompt processing system
- Prompts are now treated as events with metadata (buffer state, priority, timestamps)
- New modules: `queue.lua`, `patch.lua`, `confidence.lua`, `worker.lua`, `scheduler.lua`
- Priority-based event queue with observer pattern
- Buffer snapshots for staleness detection
- **Optimistic Execution** - Ollama as fast local scout
- Use Ollama for first attempt (fast local inference)
- Automatically escalate to remote LLM if confidence is low
- Configurable escalation threshold (default: 0.7)
- **Confidence Scoring** - Response quality heuristics
- 5 weighted heuristics: length, uncertainty phrases, syntax completeness, repetition, truncation
- Scores range from 0.0-1.0
- Determines whether to escalate to more capable LLM
- **Staleness Detection** - Safe patch application
- Track `vim.b.changedtick` and content hash at prompt time
- Discard patches if buffer changed during generation
- Prevents stale code injection
- **Completion-Aware Injection** - No fighting with autocomplete
- Defer code injection while completion popup visible
- Works with native popup, nvim-cmp, and coq_nvim
- Configurable delay after popup closes (default: 100ms)
- **Tree-sitter Scope Resolution** - Smart context extraction
- Automatically resolves prompts to enclosing function/method/class
- Falls back to heuristics when Tree-sitter unavailable
- Scope types: function, method, class, block, file
- **Intent Detection** - Understands what you want
- Parses prompts to detect: complete, refactor, fix, add, document, test, optimize, explain
- Intent determines injection strategy (replace vs insert vs append)
- Priority adjustment based on intent type
- **Tag Precedence Rules** - Multiple tags handled cleanly
- First tag in scope wins (FIFO ordering)
- Later tags in same scope skipped with warning
- Different scopes process independently
### Configuration
New `scheduler` configuration block:
```lua
scheduler = {
enabled = true, -- Enable event-driven mode
ollama_scout = true, -- Use Ollama first
escalation_threshold = 0.7,
max_concurrent = 2,
completion_delay_ms = 100,
}
```

- OpenAI API with custom endpoint support (Azure, OpenRouter, etc.)
- Google Gemini API
- GitHub Copilot (uses existing copilot.lua/copilot.vim authentication)
- **Agent Mode** - Autonomous coding assistant with tool use
- `read_file` - Read file contents
- `edit_file` - Edit files with find/replace
- `write_file` - Create or overwrite files
- `bash` - Execute shell commands
- Real-time logging of agent actions
- `:CoderAgent`, `:CoderAgentToggle`, `:CoderAgentStop` commands
- **Transform Commands** - Transform /@ @/ tags inline without split view
- `:CoderTransform` - Transform all tags in file
- `:CoderTransformCursor` - Transform tag at cursor
- `:CoderTransformVisual` - Transform selected tags
- Default keymaps: `<leader>ctt` (cursor/visual), `<leader>ctT` (all)
- **Auto-Index Feature** - Automatically create coder companion files
- Creates `.coder.` companion files when opening source files
- Language-aware templates with correct comment syntax
- `:CoderIndex` command to manually open companion
- `<leader>ci` keymap
- Configurable via `auto_index` option (disabled by default)
- **Logs Panel** - Real-time visibility into LLM operations
- Token usage tracking (prompt and completion tokens)
- "Thinking" process visibility
- Request/response logging
- `:CoderLogs` command to toggle panel
- **Mode Switcher** - Switch between Ask and Agent modes
- `:CoderType` command shows mode selection UI
### Changed
- Window width configuration now uses percentage as whole number (e.g., `25` for 25%)
- Improved code extraction from LLM responses
- Better prompt templates for code generation
### Fixed
- Window width calculation consistency across modules
---
## [0.2.0] - 2026-01-11
### Added
- **Ask Panel** - Chat interface for asking questions about code
- Fixed at 1/4 (25%) screen width for consistent layout
- File attachment with `@` key (uses Telescope if available)
- `Ctrl+n` to start a new chat (clears input and history)

- `Y` to copy last response to clipboard
- `q` to close panel (closes both windows together)
- Auto-open Ask panel on startup (configurable via `auto_open_ask`)
- File content is now sent to LLM when attaching files with `@`
### Changed
- Ask panel width is now fixed at 25% (1/4 of screen)
- Improved close behavior - closing either Ask window closes both
- Proper focus management after closing Ask panel
- Compact UI elements to fit 1/4 width layout
- Changed "Assistant" label to "AI" in chat messages
### Fixed
- Ask panel window state sync issues
- Window focus returning to code after closing Ask panel
- NerdTree/nvim-tree causing Ask panel to resize incorrectly
