Existing messages without this field will be skipped during age-based cleanup. +- Cleanup is intended for occasional manual or scheduled execution, not continuous background operation. +- The current tmux session is the authoritative source for which recipients are "online" (have corresponding windows). +- File locking uses the same flock mechanism as other AgentMail operations. +- Integer hours provide sufficient granularity for threshold configuration (no need for minutes/seconds). diff --git a/specs/011-cleanup/tasks.md b/specs/011-cleanup/tasks.md new file mode 100644 index 0000000..2f45d01 --- /dev/null +++ b/specs/011-cleanup/tasks.md @@ -0,0 +1,304 @@ +# Tasks: Cleanup Command + +**Input**: Design documents from `/specs/011-cleanup/` +**Prerequisites**: plan.md (required), spec.md (required), research.md, data-model.md, quickstart.md + +**Tests**: Tests are included as this project has an 80% coverage requirement per constitution. + +**Organization**: Tasks are grouped by user story to enable independent implementation and testing of each story. + +## Format: `[ID] [P?] [Story] Description` + +- **[P]**: Can run in parallel (different files, no dependencies) +- **[Story]**: Which user story this task belongs to (e.g., US1, US2, US3) +- Include exact file paths in descriptions + +## Path Conventions + +- **Go CLI**: `cmd/agentmail/`, `internal/cli/`, `internal/mail/`, `internal/tmux/` +- Tests colocated with source: `*_test.go` files + +--- + +## Phase 1: Setup (Shared Infrastructure) + +**Purpose**: Foundation for cleanup command -
