v0.4.0

Added

• Highlight the users' messages in the chat section: Now the chat sections highlights and spots the users' mesagges in blocks
  for a easely reading of the chat
• Rich text support in the TUI chat renderer: Added rich text rendering support for chat output in the terminal UI.
• Project-local skills system: RubyCoded can now load Markdown skill files from .rubycoded/skills/ using YAML frontmatter metadata (name, description, modes, optional tags, trigger, and priority) and expose them as reusable project instructions.
• Skill management commands: Added /skills reload and /skills list to reload and inspect project-local skills without restarting the application.
• Skill validation and cataloging: Added a dedicated RubyCoded::Skills subsystem with a markdown loader, normalized skill definitions, duplicate detection, invalid file reporting, and mode-aware in-memory cataloging.

Changed

• Refactor chat panel rendering system into multiple modules
• Prompt construction now supports project skills: Chat, plan, and agent mode instructions now append relevant project-local skills so project-specific guidance is consistently available across runtime modes, including Codex-backed sessions.
• Ruby-conventional predicate names on bridges: LLMBridge and CodexBridge now expose agentic_mode? and plan_mode? (previously agentic_mode / plan_mode). Plugins that read these predicates need to update the call site.
• Internal chat bridge refactor: Extracted RuntimeMode as the single source of truth for chat/agent/plan modes, BridgeFactory for backend selection, Tools::ExecutionPolicy for centralized risk/approval/limits, PromptBuilder for mode-aware system instructions, and BridgeCommon (ModeTransitions, ToolFlow, AutoSwitch) to share behavior between LLMBridge and CodexBridge.
• Tool execution pipeline: Added Tools::ExecutionPipeline and BaseTool#run_pipeline to standardize path validation, project-root guarding and filesystem error normalization for side-effecting tools; adopted in WriteFileTool, EditFileTool and DeletePathTool.
• Extension model documented: The README now describes the boundary between commands, skills and plugins.

v0.3.1

Added

• Git integration tool: New git tool for common git workflows in projects (status, diff, add, commit) backed by a shared GitBaseTool.

Changed

• Agent mode enabled by default: Sessions now start in Agent mode automatically instead of requiring manual activation.

v0.3.0

Added

• Pro-only Codex model handling: gpt-5.3-codex-spark and gpt-5.2-codex are tagged as pro_only in the Codex model catalog and render with a (Pro only) marker in the /model selector. Plus/free JWT plan claims now hide Pro-only models from the selector, while unknown plans keep the previous behavior to avoid breaking Pro users.
• Automatic Codex model fallback: When the Codex backend rejects a model with not supported when using Codex with a ChatGPT account, the request is transparently retried against gpt-5.4 and the user is informed via a system message.
• Provider metadata in /model: CodexModel now exposes provider metadata so the selector shows (openai) instead of (unknown).
• Unified command catalog: New RubyCoded::Commands module with a central Catalog, CommandDefinition, and provider abstraction (CoreProvider, PluginProvider, MarkdownProvider) consolidating all slash commands in a single source of truth, replacing the hand-rolled help.txt and ad-hoc registrations.
• Markdown custom commands: Users can now drop *.md files under ~/.ruby_coded/commands/ (or the project-local .ruby_coded/commands/) to define reusable slash commands with front-matter metadata, loaded via the new MarkdownLoader / MarkdownProvider.
• Context window tracking: New State::ContextWindow module plus status bar integration that shows live context usage per model, driven by per-turn token tracking.

Changed

• Status bar polish: The status bar now renders context window usage alongside the model/auth indicators and hides noisy fields when data is unavailable.
• Command handler refactor: CommandHandler is now powered by the unified catalog (core + plugin + markdown providers) and delegates custom command execution to the new CustomCommands mixin.

Fixed

• Context window indicator for ChatGPT Plus/Pro users: CodexBridge now parses the response.completed SSE event and feeds input/output/reasoning/cached token usage into State, mirroring the API path. session_context_tokens_used reflects the last turn's live prompt size via the new State#last_turn_context_tokens helper, eliminating the double-counting that happened because both bridges re-send the full history on each request.

BUFGIX: OAuth credentials lost after in-TUI login

• When logging in to OpenAI via OAuth from within the chat (/login) while already authenticated with another provider (e.g. Anthropic) and using a non-Codex model, the freshly stored OAuth credentials were wiped from ~/.ruby_coded/config.yaml. The root cause was two UserConfig instances holding independent in-memory copies of the config; when ensure_valid_codex_model! called @user_config.set_config("model", "gpt-5.4"), the stale hash (loaded before the OAuth login) was serialized back to disk, overwriting the OAuth credentials written moments earlier by CredentialsStore. Fixed by threading a single shared UserConfig through Initializer, AuthManager, CredentialsStore and Chat::App

BUGFIX: Startup crash when stored model provider is not authenticated

The CLI no longer raises RubyLLM::ConfigurationError at startup when the model saved in ~/.ruby_coded/config.yaml belongs to a provider that has no credentials on the current machine (e.g. switching computers with only Anthropic authenticated but a GPT model stored). Instead, the app falls back to the default model of the authenticated provider and shows an in-chat system message suggesting /login or /model to adjust.

v0.2.0

Added

• ChatGPT Plus/Pro OAuth authentication: Use your ChatGPT subscription to access GPT-5.x models via the Codex backend — no API credits required
• /login command: Authenticate with providers (OpenAI, Anthropic) directly from the TUI without restarting
• In-TUI login wizard: Native multi-step login flow with OAuth and API key support, replacing the old TUI-suspend approach
• CodexBridge: Dedicated HTTP client for the ChatGPT Codex Responses API with SSE streaming, stateless conversation history, tool calls, and automatic token refresh
• Codex model catalog: Local catalog of ChatGPT-available models (gpt-5.4, gpt-5.2, gpt-5.2-codex, etc.) integrated with the /model selector
• Status bar indicator: Shows (ChatGPT) or (API) next to the model name to distinguish authentication mode
• JWT decoder: Extracts chatgpt_account_id from OAuth tokens for Codex API authentication

Changed

• OpenAI OAuth now authenticates via ChatGPT Codex backend instead of the OpenAI Platform API
• OAuth scopes expanded to openid profile email offline_access with Codex-specific auth params
• AuthManager skips OpenAI OAuth credentials for RubyLLM configuration (handled by CodexBridge)
• Default OpenAI model updated to gpt-5.4
