 # Changelog
 
+## 0.4.1 — 2025-12-31
+
+### Added
+- `bookmarks` command to list your bookmarked tweets.
+
+### Changed
+- Cookie extraction now uses `@steipete/sweet-cookie` (drops `sqlite3` CLI + custom browser readers in `bird`).
+- Query ID updater now tracks the Bookmarks GraphQL operation.
+- Lint rules stricter (block statements, no-negation-else, useConst/useTemplate, top-level regex, import extension enforcement).
+- `pnpm lint` now runs both Biome and oxlint (type-aware).
+
+### Tests
+- Coverage thresholds raised to 90% statements/lines/functions (80% branches).
+- Added targeted Twitter client coverage suites.
+
+## 0.4.0 — 2025-12-26
+
+### Added
+- Cookie source selection: `--cookie-source safari|chrome|firefox` (repeatable) + `cookieSource` config (string or array).
+
+### Fixed
+- `tweet`/`reply`: fallback to `statuses/update.json` when GraphQL `CreateTweet` returns error 226 (“automated request”).
+
+### Breaking
+- Remove `allowSafari`/`allowChrome`/`allowFirefox` config toggles in favor of `cookieSource` ordering.
+
+## 0.3.0 — 2025-12-26
+
+### Added
+- Safari cookie extraction (`Cookies.binarycookies`) + `allowSafari` config toggle.
+
+### Changed
+- Removed the Sweetistics engine + fallback. `bird` is GraphQL-only.
+- Browser cookie fallback order: Safari → Chrome → Firefox.
+
+### Tests
+- Enforce coverage thresholds (>= 70% statements/branches/functions/lines) + expand unit coverage for version/output/Twitter client branches.
+
+## 0.2.0 — 2025-12-26
+
+### Added
+- Output controls: `--plain`, `--no-emoji`, `--no-color` (respects `NO_COLOR`).
+- `help` command: `bird help <command>`.
+- Runtime GraphQL query ID refresh: `bird query-ids --fresh` (cached on disk; auto-retry on 404; override cache via `BIRD_QUERY_IDS_CACHE`).
+- GraphQL media uploads via `--media` (up to 4 images/GIFs, or 1 video).
+
+### Fixed
+- CLI `--version`: read version from `package.json`/`VERSION` (no hardcoded string) + append git sha when available.
+
+### Changed
+- `mentions`: no hardcoded user; defaults to authenticated user or accepts `--user @handle`.
+- GraphQL query ID updater: correctly pairs `operationName` ↔ `queryId` (CreateTweet/CreateRetweet/etc).
+- `build:dist`: copies `src/lib/query-ids.json` into `dist/lib/query-ids.json` (keeps `dist/` in sync).
+- `--engine graphql`: strict GraphQL-only (disables Sweetistics fallback).

 # bird 🐦 — fast X CLI for tweeting, replying, and reading
 
-`bird` is a fast X CLI for tweeting, replying, and reading. It uses either GraphQL cookies or the Sweetistics API.
+`bird` is a fast X CLI for tweeting, replying, and reading via X/Twitter GraphQL (cookie auth).
+
+## Disclaimer
+
+This project uses X/Twitter’s **undocumented** web GraphQL API (and cookie auth). X can change endpoints, query IDs,
+and anti-bot behavior at any time — **expect this to break without notice**.

 ## Commands
 
 - `bird tweet "<text>"` — post a new tweet.
 - `bird reply <tweet-id-or-url> "<text>"` — reply to a tweet using its ID or URL.
+- `bird help [command]` — show help (or help for a subcommand).
+- `bird query-ids [--fresh] [--json]` — inspect or refresh cached GraphQL query IDs.
 - `bird read <tweet-id-or-url> [--json]` — fetch tweet content as text or JSON.
 - `bird <tweet-id-or-url> [--json]` — shorthand for `read` when only a URL or ID is provided.
 - `bird replies <tweet-id-or-url> [--json]` — list replies to a tweet.
 - `bird thread <tweet-id-or-url> [--json]` — show the full conversation thread.
 - `bird search "<query>" [-n count] [--json]` — search for tweets matching a query.
-- `bird mentions [-n count] [--json]` — find tweets mentioning @clawdbot.
+- `bird mentions [-n count] [--user @handle] [--json]` — find tweets mentioning a user (defaults to the authenticated user).
+- `bird bookmarks [-n count] [--json]` — list your bookmarked tweets.
 - `bird whoami` — print which Twitter account your cookies belong to.
 - `bird check` — show which credentials are available and where they were sourced from.
 
-## Engines
-
-- `--engine auto` (default) — use GraphQL first; if a Sweetistics API key is available, fall back on errors.
-- `--engine graphql` — use Twitter/X GraphQL with cookies (Chrome/Firefox/env/flags).
-- `--engine sweetistics` — use Sweetistics API key (no browser cookies needed).
-
 Global options:
 - `--timeout <ms>`: abort requests after the given timeout (milliseconds).
+- `--plain`: stable output (no emoji, no color).
+- `--no-emoji`: disable emoji output.
+- `--no-color`: disable ANSI colors (or set `NO_COLOR=1`).
+- `--cookie-source <safari|chrome|firefox>`: choose browser cookie source (repeatable; order matters).
 
 ## Authentication (GraphQL)
 
+GraphQL mode uses your existing X/Twitter web session (no password prompt). It sends requests to internal
+X endpoints and authenticates via cookies (`auth_token`, `ct0`).
+
+Write operations:
+- `tweet`/`reply` primarily use GraphQL (`CreateTweet`).
+- If GraphQL returns error `226` (“automated request”), `bird` falls back to the legacy `statuses/update.json` endpoint.
+
 `bird` resolves credentials in this order:
 
 1. CLI flags: `--auth-token`, `--ct0`
 2. Environment variables: `AUTH_TOKEN`, `CT0` (fallback: `TWITTER_AUTH_TOKEN`, `TWITTER_CT0`)
-3. Browser cookies (macOS): Firefox or Chrome profiles
+3. Browser cookies via `@steipete/sweet-cookie` (override via `--cookie-source` order)
 
 Browser cookie sources:
-- Firefox (default): `~/Library/Application Support/Firefox/Profiles/<profile>/cookies.sqlite`
+- Safari: `~/Library/Cookies/Cookies.binarycookies` (fallback: `~/Library/Containers/com.apple.Safari/Data/Library/Cookies/Cookies.binarycookies`)
 - Chrome: `~/Library/Application Support/Google/Chrome/<Profile>/Cookies`
+- Firefox: `~/Library/Application Support/Firefox/Profiles/<profile>/cookies.sqlite`

-## Media uploads (Sweetistics only)
+## Query IDs (GraphQL)
+
+X rotates GraphQL “query IDs” frequently. Each GraphQL operation is addressed as:
+
+- `operationName` (e.g. `TweetDetail`, `CreateTweet`)
+- `queryId` (rotating ID baked into X’s web client bundles)
+
+`bird` ships with a baseline mapping in `src/lib/query-ids.json` (copied into `dist/` on build). At runtime,
+it can refresh that mapping by scraping X’s public web client bundles and caching the result on disk.
+
+Runtime cache:
+- Default path: `~/.config/bird/query-ids-cache.json`
+- Override path: `BIRD_QUERY_IDS_CACHE=/path/to/file.json`
+- TTL: 24h (stale cache is still used, but marked “not fresh”)
+
+Auto-recovery:
+- On GraphQL `404` (query ID invalid), `bird` forces a refresh once and retries.
+- For `TweetDetail`/`SearchTimeline`, `bird` also rotates through a small set of known fallback IDs to reduce
+  breakage while refreshing.
+
+Refresh on demand:
+
+```bash
+bird query-ids --fresh
+```
+
+Exit codes:
+- `0`: success
+- `1`: runtime error (network/auth/etc)
+- `2`: invalid usage/validation (e.g. bad `--user` handle)
+
+## Version
+
+`bird --version` prints `package.json` version plus current git sha when available, e.g. `0.3.0 (3df7969b)`.
+
+## Media uploads
 
 - Attach media with `--media` (repeatable) and optional `--alt` per item.
-- Up to 4 images, or 1 video (no mixing). Supported: jpg, jpeg, png, webp, gif, mp4, mov.
+- Up to 4 images/GIFs, or 1 video (no mixing). Supported: jpg, jpeg, png, webp, gif, mp4, mov.
+- Images/GIFs + 1 video supported (uploads via Twitter legacy upload endpoint + cookies; video may take longer to process).
 
 Example:
 
 ```bash
-bird --engine sweetistics tweet "hi" --media img.png --alt "desc"
+bird tweet "hi" --media img.png --alt "desc"
 ```
