# Scheduled Tasks (Cron Jobs) Implementation Plan > **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking. **Goal:** Add a cron-like scheduled task system to PicoBot that triggers agent LLM prompts on a schedule (cron expression / fixed interval / one-shot), with results delivered to channels. **Architecture:** A new `src/scheduler/` module with its own SQLite store (sharing the existing `sqlx::SqlitePool` via `storage.pool()`). The scheduler runs as a tokio background task, calling `SessionManager::handle_cron_message()` directly. Agent-facing tools (cron_add, cron_list, etc.) let the LLM manage jobs. Schedule computation uses the `cron` and `chrono-tz` crates. **Tech Stack:** Rust, tokio, sqlx, `cron` 0.15, `chrono-tz` 0.10 --- ## File Structure | File | Create/Modify | Responsibility | |------|--------------|----------------| | `Cargo.toml` | Modify | Add `cron`, `chrono-tz` dependencies | | `src/lib.rs` | Modify | Add `pub mod scheduler;` | | `src/config/mod.rs` | Modify | Add `SchedulerConfig` to `GatewayConfig` | | `src/scheduler/types.rs` | Create | `Schedule`, `ScheduledJob`, `JobRun` data types | | `src/scheduler/store.rs` | Create | SQLite schema + CRUD for `scheduled_jobs` and `job_runs` | | `src/scheduler/mod.rs` | Create | `Scheduler` struct, `run()` loop, `next_run_for_schedule()` | | `src/scheduler/tools.rs` | Create | 6 agent tools: `cron_add/list/remove/enable/disable/update` | | `src/bus/message.rs` | Modify | Add `ChatMessage::user_with_source()` factory | | `src/session/session.rs` | Modify | Add `handle_cron_message()` method | | `src/gateway/mod.rs` | Modify | Create `Scheduler`, spawn background task, register cron tools | | `src/session/session_id.rs` | Modify | Add `from_components()` convenience constructor | --- ### Task 1: Add Cron Dependencies **Files:** - Modify: `Cargo.toml` - [ ] **Step 1: Add `cron` and `chrono-tz` to dependencies** After line 28 (`tempfile = "3"`), insert: ```toml cron = "0.15" chrono-tz = "0.10" ``` - [ ] **Step 2: Verify build** Run: `cargo check 2>&1` Expected: Dependencies download and resolve. No code referencing them yet, so no compile errors. - [ ] **Step 3: Commit** ```bash git add Cargo.toml Cargo.lock git commit -m "deps: add cron and chrono-tz for scheduled tasks" ``` --- ### Task 2: Add SchedulerConfig **Files:** - Modify: `src/config/mod.rs:143` (after existing `session_db_path` field) - [ ] **Step 1: Define `SchedulerConfig` struct** Add after the closing `}` of `GatewayConfig` (after line 143, before the `ClientConfig` block): ```rust #[derive(Debug, Clone, Serialize, Deserialize)] pub struct SchedulerConfig { /// Whether the scheduler is enabled #[serde(default = "default_scheduler_enabled")] pub enabled: bool, /// Poll interval in seconds (how often to check for due jobs) #[serde(default = "default_poll_interval_secs")] pub poll_interval_secs: u64, /// Maximum concurrent job executions (currently sequential, reserved for future) #[serde(default = "default_max_concurrent")] pub max_concurrent: usize, } fn default_scheduler_enabled() -> bool { true } fn default_poll_interval_secs() -> u64 { 60 } fn default_max_concurrent() -> usize { 1 } impl Default for SchedulerConfig { fn default() -> Self { Self { enabled: true, poll_interval_secs: 60, max_concurrent: 1, } } } ``` - [ ] **Step 2: Add `scheduler` field to `GatewayConfig`** In `GatewayConfig` (line 132-143), add after `session_db_path`: ```rust #[serde(default)] pub scheduler: Option, ``` The full struct becomes: ```rust #[derive(Debug, Clone, Deserialize, Serialize)] pub struct GatewayConfig { #[serde(default = "default_gateway_host")] pub host: String, #[serde(default = "default_gateway_port")] pub port: u16, #[serde(default, rename = "session_ttl_hours")] pub session_ttl_hours: Option, #[serde(default, rename = "cleanup_interval_minutes")] pub cleanup_interval_minutes: Option, #[serde(default, rename = "session_db_path")] pub session_db_path: Option, #[serde(default)] pub scheduler: Option, } ``` - [ ] **Step 3: Update `Default for GatewayConfig`** In the `impl Default for GatewayConfig` block (around line 163), add: ```rust scheduler: None, ``` - [ ] **Step 4: Verify build** Run: `cargo check 2>&1` Expected: Compiles successfully. - [ ] **Step 5: Commit** ```bash git add src/config/mod.rs git commit -m "feat: add SchedulerConfig to GatewayConfig" ``` --- ### Task 3: Create Scheduler Data Types **Files:** - Create: `src/scheduler/types.rs` - Modify: `src/scheduler/mod.rs` (stub) - Modify: `src/lib.rs` - [ ] **Step 1: Register the scheduler module** In `src/lib.rs`, after `pub mod providers;` (line 14), add: ```rust pub mod scheduler; ``` - [ ] **Step 2: Create stub `src/scheduler/mod.rs`** ```rust pub mod types; pub mod store; pub mod tools; pub use types::{JobRun, Schedule, ScheduledJob}; ``` - [ ] **Step 3: Define types in `src/scheduler/types.rs`** ```rust use serde::{Deserialize, Serialize}; /// How a job is scheduled. Serialized as JSON in the database `schedule` column. #[derive(Debug, Clone, Serialize, Deserialize)] #[serde(tag = "type")] pub enum Schedule { /// One-shot: fires once at a specific Unix millisecond timestamp, then disables. #[serde(rename = "at")] At { at: i64 }, /// Recurring: fires every `every_ms` milliseconds. #[serde(rename = "every")] Every { every_ms: u64 }, /// Recurring: fires on a cron schedule with optional timezone. #[serde(rename = "cron")] Cron { expr: String, tz: Option }, } /// A scheduled job stored in the database. #[derive(Debug, Clone, Serialize, Deserialize)] pub struct ScheduledJob { pub id: String, pub name: String, /// JSON-serialized `Schedule` stored as TEXT in SQLite. pub schedule: Schedule, pub prompt: String, pub channel: String, pub chat_id: String, pub model: Option, pub enabled: bool, pub delete_after_run: bool, pub next_run_at: i64, pub last_run_at: Option, pub last_status: Option, pub last_error: Option, pub created_at: i64, pub updated_at: i64, } /// A single execution record for a job. #[derive(Debug, Clone, Serialize, Deserialize)] pub struct JobRun { pub id: i64, pub job_id: String, pub started_at: i64, pub finished_at: i64, pub status: String, pub output: Option, pub error: Option, pub duration_ms: i64, } ``` - [ ] **Step 4: Verify build** Run: `cargo check 2>&1` Expected: Compiles successfully. - [ ] **Step 5: Commit** ```bash git add src/lib.rs src/scheduler/ git commit -m "feat: add scheduler data types (Schedule, ScheduledJob, JobRun)" ``` --- ### Task 4: Add `ChatMessage::user_with_source` and `Session::create_user_message_with_source` **Files:** - Modify: `src/bus/message.rs:198` (after `pub fn tool(...)`) - Modify: `src/session/session.rs:252` (after `create_user_message`) - [ ] **Step 1: Write the failing test** Create inline test in `src/bus/message.rs`, immediately before the closing `}` of the `impl ChatMessage` block (after line 197): ```rust pub fn user_with_source(content: impl Into, source: MessageSource) -> Self { Self { id: uuid::Uuid::new_v4().to_string(), role: "user".to_string(), content: content.into(), media_refs: Vec::new(), timestamp: current_timestamp(), tool_call_id: None, tool_name: None, tool_calls: None, source: Some(source), } } ``` No test for this factory method separately — it's pure data construction. - [ ] **Step 2: Write the failing test for `create_user_message_with_source`** In `src/session/session.rs`, after `create_user_message` (line 252), add this test: ```rust pub fn create_user_message_with_source(&self, content: &str, media_refs: Vec, source: crate::bus::MessageSource) -> ChatMessage { if media_refs.is_empty() { ChatMessage::user_with_source(content, source) } else { // For simplicity, ignore media in cron messages (media is always empty from scheduler) ChatMessage::user_with_source(content, source) } } ``` No test for this separately — it's used in `handle_cron_message` which gets tested via integration. - [ ] **Step 3: Verify build** Run: `cargo check 2>&1` Expected: Compiles successfully. - [ ] **Step 4: Commit** ```bash git add src/bus/message.rs src/session/session.rs git commit -m "feat: add ChatMessage::user_with_source and Session::create_user_message_with_source" ``` --- ### Task 5: Create SchedulerStore (SQLite Schema + CRUD) **Files:** - Create: `src/scheduler/store.rs` - [ ] **Step 1: Write the failing test** Write inline tests at the bottom of `src/scheduler/store.rs`. These test `SchedulerStore` against an **in-memory** SQLite database: ```rust #[cfg(test)] mod tests { use super::*; use crate::scheduler::types::{Schedule, ScheduledJob, JobRun}; use sqlx::SqlitePool;

use crate::scheduler::store as scheduler_store; ``` - [ ] **Step 2: Create scheduler in `GatewayState::new()`** In `GatewayState::new()` (after line 76 — after `session_manager.register_outbound_tool(...)`), add: ```rust // Initialize scheduler if enabled in config let scheduler_config = config.gateway.scheduler.clone().unwrap_or_default(); if scheduler_config.enabled { // Initialize scheduler tables in the database scheduler_store::SchedulerStore::init(storage.pool()) .await .map_err(|e| format!("failed to initialize scheduler store: {}", e))?; tracing::info!("Scheduler store initialized"); } ``` - [ ] **Step 3: Spawn scheduler in `start_message_processing()`** In `start_message_processing()` (after line 170 — after the outbound dispatcher spawn), add: ```rust // Spawn scheduler background task if enabled let scheduler_config = self.config.gateway.scheduler.clone().unwrap_or_default(); if scheduler_config.enabled { let sched = Arc::new(Scheduler::new( storage.pool().clone(), self.session_manager.clone(), scheduler_config, )); tokio::spawn(async move { sched.run().await; }); tracing::info!("Scheduler background task spawned"); } ``` Wait — there's a problem. `start_message_processing` takes `&self`, and `storage` is not a field of `GatewayState`. We need to pass the pool reference to `start_message_processing`. Let me adjust `start_message_processing` to accept a `pool: sqlx::SqlitePool` parameter, or store the pool in `GatewayState`. Looking at the existing code, `Storage` is only referenced in `GatewayState::new()` — it's not stored as a field. We need the pool. **Solution:** Store `sqlx::SqlitePool` directly in `GatewayState`. - [ ] **Step 3a: Add `pool` field to `GatewayState`** ```rust pub struct GatewayState { pub config: Config, pub workspace_dir: std::path::PathBuf, pub session_manager: Arc, pub channel_manager: ChannelManager, pub pool: sqlx::SqlitePool, // <-- add this } ``` - [ ] **Step 3b: Set pool in `GatewayState::new()`** After creating storage (line 53), clone the pool: ```rust let pool = storage.pool().clone(); ``` Then in the `Ok(Self { ... })` block, add: ```rust pool, ``` - [ ] **Step 3c: Use pool in `start_message_processing`** After the outbound dispatcher spawn block (after line 170), add: ```rust // Spawn scheduler background task if enabled let scheduler_config = self.config.gateway.scheduler.clone().unwrap_or_default(); if scheduler_config.enabled { let sched = Arc::new(Scheduler::new( self.pool.clone(), self.session_manager.clone(), scheduler_config, )); tokio::spawn(async move { sched.run().await; }); tracing::info!("Scheduler background task spawned"); } ``` - [ ] **Step 4: Verify build** Run: `cargo check 2>&1` Expected: Compiles successfully. - [ ] **Step 5: Commit** ```bash git add src/gateway/mod.rs git commit -m "feat: wire scheduler into GatewayState startup and message processing" ``` --- ### Task 9: Implement Agent Tools **Files:** - Create: `src/scheduler/tools.rs` - Modify: `src/gateway/mod.rs` (register tools) - [ ] **Step 1: Write the failing test** At the bottom of `src/scheduler/tools.rs`, add: ```rust #[cfg(test)] mod tests { use super::*;
