.github/copilot-instructions.md

gsd-task-manager copilot-instructions.md is an instructions file for GitHub Copilot from vscarpenter/gsd-task-manager. It costs 2,764 tokens per session, scanned A, original, MIT.

Project-specific coding instructions for the GSD Task Manager, a Next.js task-management application. They describe its architecture, data storage, task classification, validation rules, and key decisions.

In plain words
What is it for?
They help an agent navigate the app, understand its IndexedDB data model, and follow its existing implementation patterns.
Why use it?
They give a coding agent the conventions and technical context needed to change this particular codebase safely.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gsd-task-manager copilot-instructions.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 22d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Copilot Instructions for GSD Task Manager

This guide enables AI coding agents to work productively in the GSD Task Manager codebase. Follow these project-specific conventions and workflows for best results.

Architecture Overview

Core Stack

  • Next.js 16 App Router: All routes in app/. Matrix view: app/(matrix)/page.tsx. Dashboard: app/(dashboard)/dashboard/page.tsx. PWA install: app/(pwa)/install/page.tsx.
  • Client-side only: No server rendering. All components use "use client".
  • Data Layer: IndexedDB via Dexie v4 (lib/db.ts, current schema v13). CRUD in lib/tasks.ts. Live queries via useTasks() hook (lib/use-tasks.ts).
  • Quadrant System: Tasks classified by urgent/important booleans → 4 quadrants. Logic in lib/quadrants.ts.
  • Schema Validation: Zod schemas in lib/schema.ts for all data types.

Database Schema (v13)

  • Tables: tasks, archivedTasks, smartViews, notificationSettings, syncQueue, syncMetadata, deviceInfo, archiveSettings, syncHistory, appPreferences
  • Task Fields: Core (id, title, description, urgent, important, quadrant, completed, completedAt, dueDate, createdAt, updatedAt) + Advanced (recurrence, tags, subtasks, dependencies, notifyBefore, snoozedUntil, estimatedMinutes, timeSpent, timeEntries)
  • Indexes: Performance-critical indexes on quadrant, completed, dueDate, completedAt, createdAt, updatedAt, *tags, *dependencies, notificationSent
  • Migrations: Schema changes always require migration in lib/db.ts. See DATABASE_ARCHITECTURE.md for full ERD.
  • Schema change checklist: Zod schema changes typically require updates in three places: lib/constants/schema.ts (add/update limits), taskDraftSchema in lib/schema.ts, and taskRecordImportSchema in lib/schema.ts (a separate definition that uses .strip() — not derived from the draft schema for validation rules).

Key Architectural Decisions

  1. PocketBase cloud sync: Optional cloud sync via self-hosted PocketBase server. Tasks stored as plaintext (user owns the server). OAuth authentication with Google/GitHub.
  2. Last-write-wins conflict resolution: Conflicts resolved using client_updated_at timestamps. BFS algorithm prevents circular dependencies in task graph.
  3. Modular components: Large files split into <300 line modules. Example: lib/sync/ has 20+ focused modules vs monolithic sync engine.
  4. Pure analytics functions: All metric calculations in lib/analytics/ are side-effect-free for testability and composability.
  5. Transaction-based batch operations: lib/bulk-operations.ts ensures atomicity (all-or-nothing) for multi-task updates.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
