# AGENTS.md — Build guide for Wrike

## Project scope
Plan a small team's projects in list and board views, link milestone dependencies and review workload from explicit estimates. Keep activity history and a limited dashboard grounded in actual task states.

Catalogue verdict: kinda. The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Wrike, track projects through tasks, boards, custom fields, and team dashboards. The hard boundary is enterprise workflow, approvals, integrations, reporting, and governance, plus collaboration, integrations, and organizational trust.
Use the implementation prompt below to define the deliverable. Complete each phase's acceptance checks before extending the scope.

## Working agreement
- Inspect the repository and its existing instructions before choosing paths, dependencies or commands. Keep one coherent stack and explain changes to the proposed architecture.
- Plan a vertical slice that accepts a real input and produces the useful output described below. Persist only the state the prompt calls for; respect memory-only and upstream-managed workflows. Use fixtures only when they are clearly labelled.
- After scaffolding, document the actual install, development, check and build commands in README and keep them synchronized with the package or project manifest. Do not report commands as successful unless they ran.
- Work in small steps. At handoff, list implemented flows, checks actually performed, remaining blockers, and any credentials or provider setup the owner must supply.
- Do not publish, spend money, contact customers, delete source data or run irreversible migrations without the project owner's authorization.

## Prerequisites
- A supported Node release, PostgreSQL, HTTPS for a shared deployment, and a backup destination. Begin with one workspace and explicit owner/member permissions.
- Implementation components: Next.js App Router and TypeScript for server-rendered pages and validated mutations. PostgreSQL with Drizzle migrations; Better Auth sessions for a small private workspace.
- Scope boundary: enterprise workflow, approvals, integrations, reporting, and governance; deep integrations

## Stack and architecture
- Next.js App Router and TypeScript for server-rendered pages and validated mutations.
- PostgreSQL with Drizzle migrations; Better Auth sessions for a small private workspace.
- Domain model: projects, task hierarchies, custom fields, milestones, dependency edges, assignments and workload assumptions

## Security and data integrity
- Authorize every record read and mutation on the server using its workspace membership; validate payloads, protect mutations against CSRF, and escape user-authored HTML.
- Correctness boundary: Dependency cycles are invalid; workload is an estimate and cannot infer employee performance or silently count duplicated tasks twice.
- Commit related database changes in one transaction. Use version checks for competing edits and an outbox for external notifications; retry delivery independently of saving the record.
- Export versioned JSON plus attachments and a readable CSV summary. Restore into a separate database and compare record IDs and attachment checksums before switching.

## Agent implementation rules
- Project rule — data model: projects, task hierarchies, custom fields, milestones, dependency edges, assignments and workload assumptions
- Project rule — preserve this invariant: Dependency cycles are invalid; workload is an estimate and cannot infer employee performance or silently count duplicated tasks twice.
- Project rule — acceptance evidence: Move a task between projects and retain discussion/assignment history; a cyclic dependency is rejected with the path causing the cycle.

## Optional agent skills and references
- Optional external skill: [vercel-react-best-practices](https://github.com/vercel-labs/agent-skills/blob/main/skills/react-best-practices/SKILL.md) — Improve React and Next.js data fetching, rendering, bundle size and server performance. Review its instructions and compatibility before use; it does not grant deployment, data-access or publication permission.
- Optional external skill: [supabase-postgres-best-practices](https://github.com/supabase/agent-skills/blob/main/skills/supabase-postgres-best-practices/SKILL.md) — Review PostgreSQL schemas, queries, indexes, pooling, concurrency and row-level security. Review its instructions and compatibility before use; it does not grant deployment, data-access or publication permission.
- Optional external skill: [web-design-guidelines](https://github.com/vercel-labs/agent-skills/blob/main/skills/web-design-guidelines/SKILL.md) — Review web interfaces for accessibility, keyboard focus, forms, navigation and interaction quality. Review its instructions and compatibility before use; it does not grant deployment, data-access or publication permission.

Read the linked SKILL.md and its dependencies before adding a skill. Select only the skills matching this project's runtime and task; their documentation does not supply API access, credentials or approval to perform external actions. Pin the reviewed revision where the tool supports it. Follow the chosen agent's documented project-level installation mechanism.

## Distribution ideas
These are optional planning notes. Obtain the owner's approval before publishing or contacting anyone.
- Demonstrate the actual Wrike-inspired workflow with owned or clearly labeled sample data: Plan a small team's projects in list and board views, link milestone dependencies and review workload from explicit estimates. Keep activity history and a limited dashboard grounded in actual task states.
- Publish a reproducible walkthrough with this observable result: Move a task between projects and retain discussion/assignment history; a cyclic dependency is rejected with the path causing the cycle.
- Explain who can operate this scoped tool, its setup and ongoing costs, and these remaining product gaps: enterprise workflow, approvals, integrations, reporting, and governance; deep integrations Avoid guaranteed savings, performance scores or implied endorsement.

## Engineering roadmap
1. Phase 1 — Scope and fixtures. Implement this bounded workflow: Plan a small team's projects in list and board views, link milestone dependencies and review workload from explicit estimates. Keep activity history and a limited dashboard grounded in actual task states. Record prerequisites, select representative user-owned fixtures and document the unsupported features: enterprise workflow, approvals, integrations, reporting, and governance; deep integrations
2. Phase 2 — Durable model. Model projects, task hierarchies, custom fields, milestones, dependency edges, assignments and workload assumptions Add migrations or a versioned document format, explicit validation, stable IDs and a visible import-error report. Preserve this rule: Dependency cycles are invalid; workload is an estimate and cannot infer employee performance or silently count duplicated tasks twice.
3. Phase 3 — Complete the first useful path. Implement the workflow's input, review and output interface, with clear controls and explicit empty/error states. Commit related database changes in one transaction. Use version checks for competing edits and an outbox for external notifications; retry delivery independently of saving the record.
4. Phase 4 — Permissions and integration failure. Authorize every record read and mutation on the server using its workspace membership; validate payloads, protect mutations against CSRF, and escape user-authored HTML. Request integration credentials and permissions only for the enabled feature; show a disconnected state instead of mock results.
5. Phase 5 — Portable handoff. Export versioned JSON plus attachments and a readable CSV summary. Restore into a separate database and compare record IDs and attachment checksums before switching. Include setup, operating limits, fixture walkthrough and shutdown/restart instructions in the README.
6. Phase 6 — Acceptance scenarios. Move a task between projects and retain discussion/assignment history; a cyclic dependency is rejected with the path causing the cycle. Repeat the workflow after restart and with a denied permission or unavailable dependency; show recoverable failure rather than a success placeholder.

## Completion evidence
Demonstrate the prompt's acceptance scenarios against the scoped workflow. Include setup from a clean checkout and failure recovery. Check persistence across restart and export/restore only for the state the prompt says to store; for memory-only tools, confirm that temporary content is discarded as specified. Record actual results and remaining limitations. A detailed plan alone does not establish a working replacement.
