+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Gos is a command-line social media scheduling tool written in Go that replaces Buffer.com. It allows users to schedule and manage posts across multiple social media platforms (Mastodon, LinkedIn, and a "Noop" pseudo-platform for tracking).
+
+### Key Architecture Components
+
+- **Entry System**: Text files in `~/.gosdir/` represent posts, with filename tags controlling platform targeting and scheduling behavior
+- **Platform Abstraction**: `internal/platforms/platform.go` defines the common interface, with platform-specific implementations in subdirectories
+- **Queue Management**: Posts move through lifecycle stages: `.txt` → `.queued` → `.posted` in `~/.gosdir/db/platforms/PLATFORM/`
+- **Tag System**: Both filename tags (e.g., `post.share:mastodon.prio.txt`) and inline tags control post behavior
+- **OAuth2 Flow**: LinkedIn uses OAuth2 authentication stored in `~/.config/gos/gos.json`
+
+### Core Workflow
+
+1. Users create `.txt` files in `gosDir` (default `~/.gosdir/`)
+2. `queue.Run()` processes files and moves them to platform-specific queues
+3. `schedule.Run()` selects posts based on targets, priorities, and timing rules
+4. Platform implementations handle actual posting
+5. Posted files are marked with `.posted` extension and timestamp
+
+## Development Commands
+
+### Build and Test
+```bash
+# Build both binaries
+go-task build
+# or manually:
+go build -o gos cmd/gos/main.go
+go build -o gosc cmd/gosc/main.go
+
+# Run tests
+go-task test
+# or manually:
+go test -v ./...
+
+# Development build with race detection
+go-task dev
+```
+
+### Code Quality
+```bash
+# Lint code
+go-task lint
+# or manually:
+golangci-lint run
+
+# Vet code
+go-task vet
+# or manually:
+go vet ./...
+
+# Run fuzzing (for specific packages)
+go-task fuzz
+```
+
+### Installation
+```bash
+# Install to ~/go/bin/
+go-task install
+```
+
+## Code Structure Notes
+
+- **Main entry points**: `cmd/gos/main.go` (main app) and `cmd/gosc/main.go` (composer)
+- **Configuration**: `internal/config/` handles CLI args and JSON config file management
+- **Platform plugins**: Each platform in `internal/platforms/` implements the common `Post()` interface
+- **File processing**: `internal/entry/` handles parsing text files and extracting tags
+- **Scheduling logic**: `internal/schedule/` manages timing, targets, and post selection
+- **Tag parsing**: `internal/tags/` handles both filename and inline tag extraction
+
+## Platform Integration
+
+When adding new platforms:
+1. Create new directory under `internal/platforms/`
+2. Implement the `Post(ctx, args, sizeLimit, entry)` interface
+3. Add platform alias to `platforms.go` aliases map
+4. Handle authentication/configuration in platform-specific code
+
+## Configuration Management
+
+- Config file: `~/.config/gos/gos.json` contains API keys and OAuth tokens
+- Database: `~/.gosdir/db/platforms/` contains queued and posted files
+- Cache: `~/.gosdir/cache/` (configurable via `--cacheDir`)

@@ -75,11 +88,29 @@ Example Configuration File (`~/.config/gos/gos.json`):
 * `LinkedInRedirectURL`: The redirect URL configured for handling OAuth2 responses.
 * `LinkedInAccessToken`: Gos will automatically update this after successful OAuth2 authentication with LinkedIn.
 * `LinkedInPersonID`: Gos will automatically update this after successful OAuth2 authentication with LinkedIn.
+* `PauseStart`: (Optional) Start date for pausing all posts in YYYY-MM-DD format.
+* `PauseEnd`: (Optional) End date for pausing all posts in YYYY-MM-DD format.
 
 ### Automatically managed fields
 
 Once you finish the OAuth2 setup (after the initial run of `gos`), some fields—like `LinkedInAccessToken` and `LinkedInPersonID` will get filled in automatically. To check if everything's working without actually posting anything, you can run the app in dry run mode with the `--dry` option. After OAuth2 is successful, the file will be updated with `LinkedInClientID` and `LinkedInAccessToken`. If the access token expires, it will go through the OAuth2 process again.
 
+### Pausing posts
+
+You can pause Gos from posting any messages during a specific time period by adding `PauseStart` and `PauseEnd` dates to your configuration file. This is useful for vacations, breaks, or any period when you don't want automated posts.
+
+When both `PauseStart` and `PauseEnd` are configured, Gos will skip all posting during that period but will still queue new messages. The pause period is inclusive of both start and end dates.
+
+**Example use case**: If you're going on vacation from July 1st to September 18th, add these fields to your config:
+```json
+{
+  "PauseStart": "2024-07-01",
+  "PauseEnd": "2024-09-18"
+}
+```
+
+During this period, running `gos` will display a message indicating that posting is paused and skip all social media posts until September 19th.
+
 ## Invoking Gos
 
 Gos is a command-line tool for posting updates to multiple social media platforms. You can run it with various flags to customize its behaviour, such as posting in dry run mode, limiting posts by size, or targeting specific platforms.
