It keeps only messages received after it is connected, reads one Git repository in read-only mode, and answers short, source-grounded questions. It is intentionally not an architect, code-review system, task manager, or replacement for a senior engineer. + +## MVP boundaries + +The bot uses Telegram long polling and PostgreSQL. It does not retrieve old group history (Telegram Bot API does not expose it), create commits/PRs, index embeddings, download random group files, or turn chat/repository content into instructions. Webhooks, automatic archive extraction, and rich document workflows are deliberately outside this MVP. + +## Setup + +1. Create a bot with [@BotFather](https://t.me/BotFather), copy its token, and disable **Privacy Mode** (or make it a group administrator) so it receives ordinary group messages. +2. Add the bot to the project group. Obtain your numeric Telegram user ID and the group chat ID (they are not usernames). Set the owner as `OWNER_TELEGRAM_ID` and the group as `PROJECT_GROUP_ID`. +3. Create a DeepSeek API key and set `DEEPSEEK_API_KEY`. The API is used through its OpenAI-compatible endpoint. +4. Copy configuration and fill the required values: + +```bash +cp .env.example .env +``` + +`REPOSITORY_URL` is optional: it provides an initial fallback repository. The recommended flow is to send the owner message `посмотри этот репозиторий: https://github.com/acme/project`. Relay Bot attaches that repository to the current chat/topic. For a private HTTPS repository, set the token separately; it is injected only for the Git operation, is never persisted in the database or logged, and is not sent to the model. + +5. Start the service: + +```bash +docker compose up --build +``` + +The container runs `alembic upgrade head` before polling. PostgreSQL uses a persistent Docker volume and the bot waits for its health check. + +For local checks, use Python 3.12+: + +```bash +python -m pip install -e '.[dev]' +pytest +ruff check . +ruff format --check . +``` + +## Configuration + +Required secrets and endpoints are kept only in environment variables: + +| Variable | Purpose | +| --- | --- | +| `TELEGRAM_BOT_TOKEN` | BotFather token | +| `DEEPSEEK_API_KEY`, `DEEPSEEK_BASE_URL`, `DEEPSEEK_MODEL` | DeepSeek client configuration | +| `DATABASE_URL` | async SQLAlchemy PostgreSQL URL | +| `REPOSITORY_URL`, `REPOSITORY_BRANCH` | optional initial read-only project repository | +| `REPOSITORY_ACCESS_TOKEN` | optional private HTTPS repository credential | +| `OWNER_TELEGRAM_ID`, `PROJECT_GROUP_ID` | numeric authorization allowlist | +| `BOT_TIMEZONE`, `LOG_LEVEL` | operation settings | + +Additional limits in `.env.example` cap repository file size, attachment size, context, summary trigger, confidence, and proactive cooldown. + +## Commands + +Everyone in the configured project group or the owner’s private chat can use `/start`, `/help`, `/ask `, `/context`, `/status`, `/forget_me`, and `/cancel`. The owner can attach a repository in natural language: `посмотри этот репозиторий: https://github.com/acme/project`, or explicitly with `/repo ` (the `/syncrepo ` alias is also supported). `/sync_repo` only updates an already attached repository. + +Only the numeric owner ID can use `/set_prompt`, `/show_prompt`, `/prompt_history`, `/rollback_prompt`, `/summarize`, `/sync_repo`, `/repo_status`, `/proactive off|mentions|safe|active`, `/memory_status`, and `/settings`. `/set_prompt` opens a one-message private-chat flow. The owner’s prompt augments, never replaces, the immutable safety prompt. + +## Memory and answers + +Each incoming message is saved separately with chat, topic/thread, user, reply, edit, type, and attachment metadata. Group, owner-DM, participant-DM, and forum topics remain separate by chat/topic keys. Old originals are retained after a versioned summary is made. A summary is generated per chat/topic on `/summarize`; the service also exposes an automatic token threshold for scheduling during normal operation. + +Answers receive: immutable safety rules, active owner metaprompt, the latest summary, recent messages, and limited repository evidence. A dynamically attached repository is stored per chat/topic and cloned with Git partial-clone filtering (`blob:none`): the bot receives the Git tree and history first, then fetches the content of only a file it explicitly reads. Repository research uses a bounded tool-selection pass: directory map, filename search, safe ranged read, commit log, diff/stat, and file information. It never sends whole repositories. Answers should name an exact path or commit; absence of evidence is reported as needing a human decision. + +## Proactivity + +Default `safe` mode uses a cheap classification step and may reply without a mention only when a project question is factual, non-rhetorical, high-confidence, not a new decision, and not suppressed by duplicate/cooldown protection. `mentions` requires an explicit mention, `off` suppresses proactive replies, and `active` is reserved for extra blocker/contradiction detection. The bot does not routinely interrupt unknown questions; questions requiring a new design or management choice are left to the owner. + +## Files, privacy, and safety + +Group documents are ignored unless the bot is explicitly mentioned in the caption, the user replies with an explicit read request, or a future explicit command invokes processing. Files sent in a private bot chat are eligible. Supported MVP formats are `.txt`, `.md`, `.json`, `.yaml/.yml`, `.csv`, text-extractable `.pdf`, and `.docx`; executables and archives are rejected. Size and extracted-text limits apply. File contents are untrusted data, never policy instructions. + +Only the configured group and the owner private chat are accepted; unknown groups are ignored. Repository paths are contained under the clone, sensitive names/extensions and common generated/vendor directories are excluded, and subprocesses use argument lists rather than shell interpolation. Logs contain operational metadata, not tokens, keys, full private messages, or attachment content. `/forget_me` deletes a user’s individual message records where permitted; project summaries may retain an aggregate historical fact. + +## Common problems + +- **Bot sees only commands:** disable Privacy Mode or grant appropriate group administrator access, then re-add/restart the bot. +- **No group response:** check the numeric negative `PROJECT_GROUP_ID`, the selected proactive mode, confidence threshold, and cooldown. +- **Repository sync fails:** verify URL, branch, and private HTTPS token; do not put the token in the URL. +- **Model unavailable:** verify DeepSeek URL/key/model and retry; temporary API failures are retried with exponential backoff. +- **Database connection fails:** wait for the Compose health check and keep `DATABASE_URL` pointed at `postgres` from inside Docker. diff --git a/alembic.ini b/alembic.ini new file mode 100644 index 0000000..1c7bab8 ---
