# Changelog

All notable changes to CodeCraft. Versions follow [Semantic Versioning](https://semver.org/);
until 1.0, minor versions may contain breaking changes.

## [v202611-00008] – 2026-11-09

### Added

- **Instructions per chat:** *⋯ → Instructions for this chat* (Telegram: `/prompt`) sets rules
  that apply to every message of that chat on top of the mode – language, tone, the part of the
  project to work on. A chip in the header shows when a chat has them; forks keep them.

### Fixed

- OpenAI-compatible providers: tool results no longer carry a `name` field. Gateways that
  translate to Anthropic (opencode) rejected the request with "anthropic-messages cannot
  preserve named conversation participants".
- Telegram: the token field is no longer filled in by the browser's password manager, the bot
  token is found in whatever is pasted (also the whole BotFather message), and a wrong format
  gets a clear message instead of "HTTP 404".

## [v202611-00007] – 2026-11-09

### Added

- **Telegram bot as a chat interface:** every user can connect their own bot (*Settings →
  Account → Telegram*: token from @BotFather, then `/start <code>` pairs it with their Telegram
  account – other chats are ignored). Messages, photos and files go to the current session; the
  agent's steps show live, the answer comes formatted, images from tools come as photos, and
  approvals and questions have buttons. Commands like the terminal client: `/sessions`,
  `/session`, `/new`, `/clear`, `/mode`, `/model`, `/permissions`, `/effort`, `/stop`, `/status`,
  `/costs`, `/memory`, `/jobs`, `/compact`, `/help`. The server polls Telegram – no public
  webhook needed.

## [v202611-00006] – 2026-11-09

### Added

- The image contains the Docker CLI (static client). With the host's `/var/run/docker.sock`
  mounted (and its group), admins' agents and terminals can use the host's Docker;
  `scripts/move-server.sh --docker-sock` sets this up on a new host.
- `scripts/move-server.sh --tools-dir DIR`: agent home, users' homes and `/tmp` on a separate disk.

## [v202611-00005] – 2026-11-09

### Fixed

- Commits by agents, terminals and the git panel always use the name and e-mail from
  *Settings → Account → Git* – also in repositories that have their own `user.name`/`user.email`
  (agents had set those as a workaround while no identity was configured). Agents are told not
  to change the git identity.

## [v202611-00004] – 2026-11-09

### Added

- **Chats side by side:** *Open beside* in a chat's sidebar menu shows up to three chats as
  columns, each with its own tabs and composer (desktop).
- **My modes:** every user can create personal modes under *Settings → My modes* (kind, tools,
  read-only, prompt, model); they appear only for that user.
- **Budget warnings** as push notifications for admins (warning share and 100 %) for the total,
  provider and image budgets and the opencode Go windows; the status overlay shows all budgets.
- `scripts/move-server.sh` moves an installation to another Docker host with bind mounts
  (e.g. Unraid), `scripts/smoke-test.sh` checks a running instance.

### Changed

- File manager tabs of a chat are stored on the server, so they are the same on every device.

## [v202611-00003] – 2026-11-09

### Added

- The Docker image ships the terminal client again (static Linux x86_64 and aarch64 binaries):
  `curl -fsSL https://<your-server>/cli/install.sh | sh`, download links in the settings and
  `codecraft update` work without building from source.
- File manager: *Open chat here* in a folder's menu starts a chat in that folder.
- **Tabs in a chat:** open terminals and file managers next to the chat (topbar buttons or
  "+" in the tab strip), as many as needed. Terminals of a chat keep running on the server until
  they are closed, so they are there again after a reload or on another device (output is
  replayed); they end when the chat is deleted or the server restarts.
- **Chat mode:** *New session → Just chat* (and mode `chat`) for plain conversation – a lean
  prompt with date and personal memory, web search and fetch only, no project or files.
- **Own modes:** *Settings → Agents & commands → New mode* with kind (coding or conversation),
  read-only switch, tool checkboxes, prompt, model and review loop; custom modes show up in
  *New session* and the mode selector.
- The chat shows when the conversation is being compacted – automatically because the context
  is nearly full (with tokens and share of the limit) or on request – and labels the summary.

### Changed

- The mode selector in the composer is a dropdown.

### Removed

- *Settings → Config file* no longer offers to move `${NAME}` values into the configuration (a
  one-time migration); `${NAME}` references keep working.

### Fixed

- Session updates from background tasks (title, token usage, phase, todos) and from the UI
  no longer overwrite each other. Often the first answer's token usage was lost, so automatic
  compaction and the context display started one turn late.

## [v202611-00002] – 2026-11-09

### Added

- **opencode prices:** *Fetch prices* reads prices, context and output limits, image input and
  reasoning from opencode's model list (Zen and Go), including long-context tiers and
  peak-hour or date-based factors. Costs apply them per request (`price_tiers`,
  `price_multipliers` on a model).
- **opencode costs and Go limits:** the cost opencode reports per response is recorded instead
  of an estimate, and with a *plan limit* on the provider the Go allowance is tracked in the
  5-hour, 7-day and monthly windows (budget table and status overlay; usage through CodeCraft
  only).
- **Settings → Config file** lists `${NAME}` references and moves the values of set variables
  into the configuration, so `.env` only needs deployment settings.

### Changed

- Examples and forms no longer suggest environment variables for keys; `.env.example` holds
  deployment settings only.

## [v202611-00001] – 2026-11-09

### Added

- **Image generation picks the model:** the agent drafts cheap previews, asks which one to
  refine (with the price of the final model), then creates the final image with the best model
  for the purpose (photo, illustration, text, design). Models that take a reference image
  (Nano Banana Pro edit) refine the chosen draft. Known fal.ai models come with sensible
  defaults; `stage`, `good_for` and `reference_param` in `[images].models` override them.
- **Restore a backup** in *Settings → Audit*: a stored backup or an uploaded zip. The current
  state is backed up first (`…-before-restore.zip`), then CodeCraft restarts with the restored
  database and configuration.
- **Test connection** in the provider form checks URL and key before saving.
- **Status LEDs** in the sidebar for server connection, models and MCP servers (green, yellow,
  red in vivid variants of the theme colors); a click opens an overview of every provider and
  MCP server with its state, latency and tool count.
- `scripts/release.sh`: tag, multi-arch image and Gitea release in one step.

### Changed

- Saving a provider (or reloading providers) checks its status right away instead of at the
  next five-minute check.

### Fixed

- opencode Zen/Go: requests carry the session in `x-opencode-session`; opencode Go rejected
  them without it ("Request is missing x-opencode-session").
- Two backups in the same second no longer overwrite each other.

## [0.1.0] – 2026-11-09

First public release.

### Agents and chat

- Agent loop with streaming, task lists, subagents (parallel and in the background, on other
  models), skills, slash commands, `AGENTS.md` / `CLAUDE.md`, automatic context compaction.
- Modes: **build**, **plan** (read-only) and **craft** (study a website, app, game or old
  program and build your own version, with visual comparison, clean room or deep mode),
  plus custom modes and subagents. Review loops per mode.
- Tools: files, shell with background processes, web fetch and search, LSP diagnostics after
  edits, OpenSCAD for 3D printing, Ghidra for old binaries, image generation (fal.ai), and an
  interactive **browser** (click, type, run JavaScript, screenshots, console errors; private
  network addresses are blocked).
- MCP servers (stdio and Streamable HTTP, elicitation, tools loaded on demand).
- Permissions per tool and per shell command pattern, modes *ask*, *auto*, *accept edits* and
  *bypass*; permission cards with diffs; questions from agents and MCP servers.
- Checkpoints and rewind, fork, regenerate, accept changes hunk by hunk, git worktrees per
  session, reasoning effort per message, voice input, `@file` mentions, attachments.
- Project memory (`.codecraft/memory.md`, written by the agent) and personal memory.
- Hooks before and after tool calls, on prompts and at the end of a turn.

### Models

- Anthropic natively and every OpenAI-compatible API (Gemini, OpenRouter, opencode,
  fal.ai, Ollama, vLLM, llama.cpp, LM Studio).
- Prices per model, concurrency limits per host and model, monthly budgets.
- **Model fallback** when a host is unreachable or a budget is used up.
- **Provider status**: every 5 minutes each provider's model list is checked (no tokens).

### Web app

- Installable PWA with push notifications (permissions, questions, finished turns) and a
  **share target**: text and links shared from other apps start a chat or go into a recent one.
- Guided start screen, file manager with previews (PDF, Office, 3D models, images), web
  terminal, image gallery, git panel.
- **Command palette** (Ctrl/Cmd+K) and keyboard shortcuts; **prompt templates** with
  placeholders (personal and global); sessions can be **pinned, archived and filed into
  folders**, grouped by date or project.
- Statistics: tokens, cache hits, time to first token, prefill and output speed and cost per
  request; cost and tokens per day, an activity heatmap of the last 14 days, tables per model,
  provider, mode, user and session. Optional **daily cost summary** as a push at 20:00.
- 15 colour themes, each light and dark; English and German.
- "What's new" after updates; admins see when a new release is available.

### Automations and integrations

- **Automations**: agents on a cron schedule from a Markdown job file, created by an agent,
  from a **template** or by hand; **incoming webhooks** start them (shared secret or
  Gitea/GitHub HMAC signature; the payload is passed to the agent).
- **API tokens** with full or read-only scope.
- **Prometheus metrics** at `/metrics` (own bearer token) and JSON logs
  (`CODECRAFT_LOG_FORMAT=json`).
- **Backups**: daily zip of database and config, keep 30, optional copy to any S3-compatible
  bucket; download from the settings.

### Terminal client

- `codecraft`: a full-screen terminal client like Claude Code or opencode. The agent loop,
  tools and history stay on your machine; models, modes, rules, skills and the theme come
  from the server, which counts usage and costs. Also runs **without a server**: a guided
  setup connects Anthropic, OpenAI, Gemini, OpenRouter, opencode or local servers (Ollama,
  LM Studio, llama.cpp/vLLM, detected automatically).
- No prebuilt binaries in this release: install it from source with
  `cargo install --locked --git https://git.familie-zink.org/zink/codecraft codecraft-cli`.

### Users and security

- Local accounts (Argon2) and single sign-on via OpenID Connect; admins and users, private
  folders per user, shared folders, read-only session sharing, audit log.
- Shell commands of non-admin users run in a bubblewrap sandbox.
- Multi-arch Docker image (amd64, arm64).
