1. Executive Summary

Wursor is a development environment built for people who ship on WordPress. It combines an AI agent that can plan and edit real project code with a live WordPress runtime, WP-CLI, database awareness, and preview — so building a theme, plugin, or block is not split across five apps and a hope that the model "knows WordPress."

WordPress work is not generic app development. The product surface is a CMS platform with themes, plugins, hooks, a block editor, content in MySQL, and a long tail of agency and product workflows. Today's stack forces builders to keep that reality in their head while jumping between an editor, a local site tool, wp-admin, a terminal for WP-CLI, and a database client.

Wursor makes that reality the environment:

  • A site you can boot, browse, reset, and inspect sits beside the code.
  • The agent is taught WordPress semantics — template hierarchy, hooks, block.json, capabilities, text domains — not only PHP syntax.
  • Changes show up as reviewable code diffs and, when content or options must move, as explicit State Diffs (WP-CLI / migration scripts), never silent database edits.
  • Blocks and block themes are first-class: theme.json, patterns, template parts, and editor preview.
  • Environments matter: local → staging → production, with write access gated by policy.

The opportunity: become the default professional workspace for WordPress product and agency teams in an agent-assisted era — without pretending WordPress is "just another repo."


2. Problem Statement

2.1 WordPress is a platform, not a folder of PHP

Competent general coding agents still miss what breaks real WP projects:

  • The split between code (themes/plugins) and content/state (posts, options, post meta, transients).
  • Load order and hook timing (plugins_loaded vs init vs wp_enqueue_scripts).
  • Child themes, template hierarchy, and the dual world of classic vs block themes.
  • WP-CLI as the practical automation layer.
  • Multisite, capabilities, nonces, and auth patterns.
  • Block development (block.json, render.php, editor scripts, @wordpress/scripts).

The failure mode is confident patches that enqueue wrong, ignore APIs WordPress already provides, or "fix" a theme without ever loading the site.

2.2 The toolchain is fragmented

Concern Typical tool today
Edit code General IDE / editor
Run site Local WP, DDEV, Lando, wp-env, Docker
Admin / content wp-admin in a browser
Automate WP-CLI in a separate terminal
Database phpMyAdmin / TablePlus
Assist Chat tools with no live site context
Deploy FTP, rsync, Git + host pipelines, site managers

Every hop drops context. Nothing in that chain can scaffold a block, flush rewrites, open the editor, and prove the front end in one continuous run.

2.3 Agencies and product teams buy turnaround

WordPress shops compete on speed and reliability. Friction is environment spin-up, safe changes across code and data, regression checks on real themes, and handoff between design, content, and engineering. Host "AI" features aimed at writing posts do not solve that.

2.4 Blast radius is real

WordPress sites are high-value targets. An agent that can edit wp-config.php, install arbitrary zips, or run unchecked SQL is a liability. Safe-by-default permissions are a core product requirement.


3. Vision & Opportunity

Vision: Open a WordPress project in Wursor and you get a workspace that already understands the shape of the project, can start the site, and can take a job like "add a pricing block that matches our patterns and verify it on /pricing" through edit → CLI → preview → review in one place.

Wursor sits at the intersection of:

Category What exists What Wursor adds
AI-assisted coding General editors and agents WP-native tools, playbooks, and site loop
Local WP environments Local, DDEV, wp-env Runtime embedded and controllable by the agent
In-admin AI helpers Host and plugin copilots Real engineering workspace (Git, diffs, tests), not post drafting
Block / theme tooling @wordpress/scripts, theme.json editors Unified with agent + live preview

Positioning: Wursor is the agentic WordPress workshop — not a generic coding assistant with a WordPress sticker, and not an AI writing widget inside wp-admin.


4. Target Users & Personas

4.1 Primary — Agency WordPress Engineer

Ships custom themes/plugins for clients on deadline. Wants faster scaffolding, safer refactors, fewer context switches. Uses Git; distrusts mystery FTP deploys.

4.2 Primary — Plugin / Block Product Developer

Ships commercial or open-source plugins and block libraries. Needs scaffolding, wp-env, WPCS, tests, and release hygiene. Cares about headers, text domains, and build pipelines.

4.3 Secondary — Technical Founder / Solo Builder

Runs a business on WordPress (WooCommerce, membership, LMS). Wants senior-WP leverage without a full bench.

4.4 Secondary — Design Engineer on Block Themes

Lives in theme.json, patterns, and template parts. Needs structured edits plus visual proof.

4.5 Tertiary — Technical PM / Solutions Architect

Scopes builds, reviews proposed changes, cares about migration plans and staging checks.

Out of scope for v1: content-only users who mainly need AI inside wp-admin to draft posts.


5. Product Principles

  1. Site is a runtime, not a folder — If it cannot boot, browse, and assert against WordPress, it is guessing.
  2. Code and state are both first-class — File diffs and explicit State Diffs; no silent DB mutation.
  3. WordPress semantics over generic PHP — Prefer platform APIs, hooks, and patterns a senior WP engineer would choose.
  4. Safe by default — Capability-scoped tools; production gated; secrets redacted; destructive ops require confirmation.
  5. Preview is proof — The agent cannot mark a task "done" without a verify step (screenshot, HTTP check, or editor verification). Users may dismiss the proof; the agent may not skip producing it.
  6. Git records code; scripts record state — Migrations and WP-CLI plans are reviewable artifacts.
  7. Opinionated for WordPress — Defaults follow WPCS, wp-env, and block-era workflows; escape hatches exist but are not the center.

6. Core Concepts & Mental Model

6.1 Workspace = Project + Site

A Workspace binds:

  • A Git project (theme, plugin, plugin monorepo, wp-content checkout, or Composer/Bedrock layout)
  • A site runtime (wp-env by default; Docker / Local / DDEV import paths)
  • Environment config (local / staging / production endpoints and a credentials vault)

v1 scope (locked): wp-env is the only supported runtime in v1. Local / DDEV / Bedrock import is P1 (§7.2.6). The runtime manager is still abstraction-bound (§8.1) so adding those backends later does not require a redesign.

6.2 WordPress Knowledge Graph

Indexed understanding of:

  • Themes / child themes / active theme
  • Plugins (active, mu-plugins, drop-ins)
  • CPTs, taxonomies, REST routes
  • Hook registrations (best-effort from code)
  • Block inventory (block.json)
  • theme.json tokens and style variations
  • Template hierarchy for key routes

Build source (locked): two passes. (1) Static — scan of *.php, block.json, theme.json, and plugin/theme headers at project open, refreshed on file-save and on git checkout. (2) Runtime — when the site is up, enrich via WP-CLI (wp plugin list, wp theme list, wp post-type list, wp rewrite list) with the actual active theme, active plugins, registered CPTs/taxonomies, and REST routes.

Freshness model: every graph node carries a source stamp (static vs runtime) and timestamp. Both the agent context and the UI surface staleness explicitly (e.g., "active theme — static scan, site not loaded"). Full re-index runs on project open and on every site.browse boot; incremental updates follow file-save events. Runtime nodes are re-verified each time the site boots.

6.3 The build loop

Plan → edit files → run WP-CLI / tests → refresh preview → read logs → revise. Every step uses WordPress-aware tools.

6.4 State Diffs

When a task needs content or options changes, Wursor proposes a State Diff: WP-CLI commands and/or a migration script — never an invisible database tweak. The lifecycle is explicit:

  1. Create — the agent generates a candidate diff (WP-CLI commands, SQL statements, or a PHP migration), each step annotated with intent and blast radius.
  2. Review — shown in the State tab; every step expands to full text and effect; nothing runs without review.
  3. Stage — approved steps form a numbered plan; steps can be reordered or dropped.
  4. Apply — executes against the local environment by default; each step streams output and marks pass/fail.
  5. Verify — the agent re-checks the site (option read-back, URL load, screenshot) before the diff counts as applied.
  6. Commit — migration-style state scripts commit to the repo as db/ migrations; pure WP-CLI plans persist as reviewable .state-diff.json artifacts under .wursor/state-diffs/.

Rollback (locked): destructive steps must declare an inverse at create time (e.g., wp option delete paired with the prior value) or an explicit "manual backup required" acknowledgment; Wursor refuses to stage a destructive step without one.

6.5 Rules & Playbooks

Project guidance lives in WORDPRESS.md / .wursor/rules (standards, banned patterns, deploy checklists). Playbooks are reusable workflows: scaffold a dynamic block, spin a child theme, register a CPT, harden a plugin release.

6.6 Environments

  • Local — full control for the agent under user policy
  • Staging — sync down and careful promote
  • Production — read/observe by default; write only with explicit break-glass

7. Feature Requirements

P0 = launch-blocking · P1 = ~3060 days post-launch · P2 = strategic

7.1 P0 — Launch Blocking

7.1.1 Agentic editing workspace

  • Project-aware chat with file/symbol/doc context
  • Inline rewrite of selections
  • Multi-file agent runs with reviewable patches
  • Integrated terminal
  • Git status, diff review, commit assist
  • Project rules (WORDPRESS.md, .wursor/rules)

7.1.2 WordPress project intelligence

  • Detect project shape: classic theme, block theme, single plugin, wp-content tree, Bedrock/Composer
  • When the site is up: map active theme and plugins
  • PHP + block JS support with WordPress stubs
  • Template hierarchy and block.json awareness

7.1.3 Embedded local site runtime

  • Start/stop/reset via wp-env — the only supported runtime in v1 (the emitted Docker compose file is for debugging, not an alternative surface)
  • Embedded preview (front end + wp-admin)
  • Log tail (PHP / web server; Query Monitor later)
  • Runtime manager is abstraction-bound (§8.1); Local / DDEV import (P1) plugs in behind the same interface

7.1.4 WP-CLI as an agent tool

  • Allowlisted WP-CLI runner
  • Recipes: scaffold plugin/theme/block, rewrite flush, cache flush, activate plugins, local DB export/import
  • Preview destructive commands before run

7.1.5 Permissions & safety

  • Tiers: read FS, edit FS, WP-CLI safe, WP-CLI destructive, SQL read, SQL write, network install
  • Production writes off by default
  • Redact secrets from .env / wp-config in agent context; scan on apply

7.1.6 Preview verification

  • Verify runs by default on every agent task and is required before the agent marks a task "done" (Principle 5); users may dismiss the proof, the agent cannot skip producing it
  • Verify step: load URLs, screenshot, HTTP status + basic error sniff (PHP error log, 500s)
  • For block tasks: open editor routes and confirm the block can be inserted (lightweight P0)
  • Failures surface explicitly — "verify failed: /pricing returned 500" with the log excerpt — never a silent retry

7.1.7 Scaffolding playbooks

  • Plugin (headers, text domain, optional Composer/PHPUnit)
  • Static / dynamic block (@wordpress/scripts)
  • Child theme
  • CPT + REST + minimal admin UI

7.1.8 First-run experience

  • Install: single signed app bundle (macOS + Windows; Linux best-effort); no Docker prompt before first project open
  • First open: guided "open a project" with three paths — a WordPress repo (auto-detects wp-env config), a plain theme/plugin folder, or a built-in sample project
  • Dependency check: Docker / wp-env detection with one-click install guidance and a diagnostic panel — a dead end is not an option
  • First preview target: ≤ 10 minutes p50 from install to a live preview (§11)

7.2 P1 — Follow-on

7.2.1 Database & options introspection

  • Read-only schema explorer and options search
  • Explain an options row with link-back to plugin code when possible
  • State Diff generation for options / post meta

7.2.2 Block & FSE workshop

  • Structured theme.json editing + agent tools
  • Pattern export/import as files
  • Best-effort jump from preview selection → template part / block source

7.2.3 Quality gates

  • PHPCS + WordPress Coding Standards
  • PHPUnit / e2e hooks (Playwright or wp-env-based)
  • Agent runs configured gates before marking work done

7.2.4 Staging connectors

  • Explicit, logged pull of DB/media from staging
  • Deploy via GitHub Actions / host APIs
  • Production DB pull requires double confirm + scrubbing warnings

7.2.5 Hook & REST introspection

  • Live REST route list from the site
  • Assist for add_action / add_filter discovery

7.2.6 Import paths

  • Open Local WP / DDEV projects
  • Zero-config open for existing wp-env repos

7.3 P2 — Strategic

  • WooCommerce-oriented skills
  • Multisite tools
  • Host integrations (WP Cloud, SpinupWP, Rocket.net, etc.)
  • Team workspaces and shared playbooks for agencies
  • Sandboxed maintenance agent (updates, conflict triage)
  • Optional design intake (e.g. Figma → patterns)
  • Headless / hybrid (Faust, Next) workspaces

8. Architecture & System Design

8.1 Layers

Shell decision (locked): Native desktop app built on Tauri + Monaco Editor. Tauri (Rust shell, system webview) gives fast startup (~0.30.8s), low memory (100200MB), and native filesystem/Docker/process access. Monaco Editor is the same editor component that powers VS Code — editing, language services, and diff views without Electron's Chromium overhead. Rust owns the tool bus, knowledge graph parser, permission engine, and runtime manager; the webview renders the editor and Wursor panels (TypeScript/HTML).

Why not Electron + Code-OSS: Electron ships an entire Chromium per app (500MB1GB memory, 26s startup) — a constant quality-of-life cost for a daily-driver dev tool. Tauri uses the OS webview, which is already resident.

Why not Zed: immature ecosystem, no Monaco/VS Code editor quality, and its agent story is not Claude/Grok-style tool-calling. The product is the WP+agent loop, not the editor.

Layer Responsibility
Workspace shell Tauri window, Monaco Editor, Wursor panels (preview, diff, state, chat), terminal
WP language services PHP/JS, stubs, block.json, theme.json schemas (Monaco language services + WP stubs)
Site runtime manager wp-env/Docker lifecycle, ports, credentials (Rust; abstraction-bound for future backends)
Agent tool bus Files, WP-CLI, HTTP preview, DB read, linters (Rust; one tool schema per tool)
Knowledge index Code index + WP graph (Rust parser; static scan + runtime enrichment)
Policy engine Permissions, environment gates, secret redaction (Rust)
Preview / verify Embedded webview, screenshots, HTTP checks, error sniff
Connectors GitHub, staging hosts, optional design tools

8.1.1 Agent substrate (locked)

  • Model: Grok (xAI) — agentic coding model; BYO API key at launch
  • Routing: All agent traffic goes through the user's own API key — no Wursor-hosted model tier in v1
  • Tool-calling protocol: Every agent tool (§8.3) is a single tool schema, not a prompt chain. The agent calls tools; the tool bus executes against the local environment
  • Fallback: If the model is unreachable or returns an error, the agent panel shows a clear "Model unavailable" state with the raw error, logs, and a retry button. The workspace shell (editing, terminal, preview) remains fully functional
  • P1 upsell: Optional Wursor-hosted routing tier for users who prefer a managed key or bundled tokens

8.2 Default local stack

  • wp-env for local + CI parity (sole runtime in v1; runtime manager abstraction-bound for future backends)
  • MySQL as default; optional ultralight SQLite path for demos only
  • Node LTS for block builds

8.3 Initial agent tools

  • fs.read / fs.write / fs.apply_patch
  • wpcli.run (categorized)
  • site.browse / site.screenshot
  • site.request (front / REST)
  • db.query (read-only default)
  • lint.phpcs / test.phpunit
  • index.search / wp.graph.lookup

8.4 Example flow

  1. "Add an FAQ accordion block and show it on /pricing."
  2. Detect theme type, build setup, existing patterns.
  3. Scaffold and register the block; wire pattern or template.
  4. Build assets; flush as needed via WP-CLI.
  5. Load /pricing and editor insert path; capture proof.
  6. Present file diffs (+ State Diff if any); user accepts.

8.5 Error & offline states

State What Wursor does
Docker not installed Detect at project open; show diagnostic panel with one-click install guide; app remains usable for file editing and git
wp-env not found Offer to install via npm; fall back to npx
Site won't boot Stream logs live; highlight the first error; offer "reset" and "last known good config"
Model unreachable Show raw error + retry; workspace shell stays fully functional
API key invalid / expired Prompt for key update inline; no data loss
Network offline Cache last-known graph state; agent panel shows "offline" warning; local site and editing unaffected
File permission denied Surface the OS-level error; no silent fallback to a different path

9. UX Notes

  • Dark-first, dense workshop UI; calm over theatrical
  • Site status bar: environment, WP version, active theme, permission mode
  • Diff view: Files tab + State tab
  • Preview: dockable; device widths; view-as role (Admin / Editor / Customer)
  • Keyboard-complete for agent flows; escape hatch from preview focus

10. Competitive Landscape

Product type Strength Gap Wursor fills
General AI code editors Strong general coding agents No WordPress runtime loop or WP semantics
Classic PHP IDEs Deep PHP tooling Weak agent-native site loop
Local WP apps Easy site spin-up Not an engineering agent workspace
wp-env / DDEV Solid runtimes CLI-centric; no integrated agent UX
Host / plugin AI Handy in wp-admin Content-oriented; not Git/theme/plugin shipping
Page builders Fast visual pages Different paradigm; not Wursor's v1 center

Moat: WP knowledge graph + controllable runtime + policy-aware tools + verify-via-preview, packaged as playbooks agencies and plugin teams repeat weekly.


11. Metrics & Success Criteria

Metric Baseline 6-month target Owner How we measure
Time to first local preview from new workspace TBD (Phase 0 spike) ≤ 10 min p50 Eng lead In-app timer from project open to first rendered preview
Accepted agent runs on P0 playbooks (little rework) TBD (alpha 1) ≥ 60% PM Per-playbook accept/reject event, tagged by playbook
Verify step catches issues before accept TBD (alpha 1) ≥ 30% of failing tasks PM Verify-fail event before accept, per task
Trial → weekly habit by week 4 TBD ≥ 40% PM Weekly active usage per trial cohort
Paying seats n/a TBD with pricing GTM Billing records

Measurement plan: all metrics instrumented from first alpha build (Phase 2). Every metric is a dashboarded event, not a manual tally. Baselines are collected during closed alpha (1020 agencies / plugin teams) and reviewed as Phase 2 exit criteria.

Qualitative bar: experienced WordPress engineers say it behaves like someone who has shipped WP for years.


12. Phased Roadmap

Phase 0 — Pivot & spec (now)

  • Clear prior product codebase
  • PRD + naming
  • Spike: wp-env control plane + agent tool bus

Phase 1 — Foundation (weeks 18)

  • Ship Tauri shell on Monaco Editor (reused editor component; no greenfield chrome)
  • Project open + WP detection
  • wp-env lifecycle + preview
  • Agent chat + diffs + rules
  • WP-CLI tool + permission engine
  • P0 playbooks

Exit criteria: a new user on a clean machine (no Docker, no wp-env) reaches a live preview of a WordPress repo in ≤ 10 minutes, and a P0 playbook (dynamic block) completes with a verified preview + accepted diff.

Phase 2 — Intelligence (weeks 916)

  • Knowledge graph v1 (static + runtime passes)
  • WPCS / tests in the loop
  • State Diffs + read-only DB introspection
  • Careful staging pull
  • Closed alpha (1020 agencies / plugin teams)

Exit criteria: all §11 baselines collected and reviewed; knowledge graph staleness surfaced in UI; State Diff create→rollback loop demoed on a destructive option change.

Phase 3 — Professional (weeks 1728)

  • Block / FSE workshop
  • Role-based preview
  • Host deploy connectors
  • Shared team playbooks
  • Paid beta

Phase 4 — Platform

  • WooCommerce, multisite, maintenance agents, ecosystem connectors

13. Risks & Mitigations

Risk Impact Mitigation
Building a full workspace is large High Tauri + Monaco (reused editor component, no greenfield editor); WP runtime + tools get the focus
Local Docker/wp-env pain (esp. Windows) High Diagnostics-first first-run; installer guides; early Local/DDEV import (P1)
Agent harms a site High Permission tiers; local-default; production lock; State Diffs with rollback
"Prompts in my current editor are enough" Medium Demo the site loop and playbooks general setups fail
Legacy PHP / chaotic themes Medium Stubs, WPCS, honest limits; playbooks for clean paths first
Repo still named originmain Resolved Repo renamed to SinachPat/wursor
Trademark / "WordPress" in marketing Medium Follow WordPress Foundation trademark rules
LLM provider outage / model churn Medium BYO-key model; workspace shell stays usable offline; P1 hosted routing tier
Docker Desktop licensing for commercial use Low Document; wp-env alternatives; Rancher Desktop path

14. Decisions & Open Questions (Phase 0)

Resolved (locked)

  1. Shell: Native desktop app on Tauri (Rust shell, system webview) + Monaco Editor (the editor core that powers VS Code). Fast startup (~0.30.8s), low memory (100200MB), native filesystem/Docker/process access, offline-capable. Rust backend; webview UI in TypeScript.
  2. Name: Wursor (locked in v1.2; no further rename planned).
  3. Repo: renamed to SinachPat/wursor.
  4. Pricing: seat-based ($X/dev/month, free tier with per-seat limits); agency teams primary. Final $X set during Phase 3 paid beta.
  5. Roots/Bedrock/Trellis support: P1 (not v1). wp-env covers the launch segment; runtime manager is abstraction-bound for later import.
  6. Models: Grok (xAI) via BYO API key (v1); optional Wursor-hosted routing tier (P1 upsell). No local model support in v1.
  7. Runtime backends: wp-env only in v1; Local / DDEV import is P1.

Remaining (genuinely open)

All Phase 0 questions are resolved above. New questions will be documented per phase and resolved before the next phase begins.


15. Appendices

A. Glossary

  • Workspace — Project + site runtime + environment config bound together
  • State Diff — Reviewable WP-CLI / SQL / content mutation plan with a create→review→apply→rollback lifecycle
  • Playbook — Reusable agent workflow with tools and checks
  • WP Knowledge Graph — Map of themes, plugins, blocks, hooks, REST (static scan + runtime enrichment)
  • Runtime — The site execution environment (wp-env in v1)
  • Environment — A target (local / staging / production) with endpoints and policy
  • Verify — The proof step (screenshot / HTTP check / editor confirmation) required before a task is "done"
  • FSE — Full Site Editing (block themes)
  • wp-env@wordpress/env local environment

B. P0 playbook sketches

  1. Dynamic block — detect build → scaffold → register → build → verify in editor → diff
  2. Child theme — scaffold → enqueue parent → override template → screenshot home
  3. CPT — register → flush rewrites → seed via WP-CLI → REST check → diff

C. Non-goals (v1)

  • Replacing wp-admin for authors
  • Unattended production hotfixes
  • Competing with Elementor-class page builders as the core offer
  • Equal-class support for every legacy builder shortcode ecosystem on day one
  • A public extension/plugin API — connectors are internal; third-party integration ships after platform phase
  • Local / DDEV / Bedrock imports — P1 (§7.2.6)
  • Managed/hosted model tier — P1 upsell
  • Accessibility certification (WCAG) or i18n / localization — v1 is English-only with no formal accessibility conformance target. Basic keyboard navigation and screen reader support come from Monaco and the webview's standard web accessibility practices; custom Wursor panels will not be audited until Phase 3.

C.1 Wursor's own test strategy

  • Unit + integration tests for the agent tool bus (each tool schema), the permission engine, and the State Diff lifecycle
  • Fixture-based WP repos in CI (wp-env in GitHub Actions) to test detection, indexing, and playbooks without a live install
  • E2E smoke on the Tauri shell: open → detect → boot → preview → verify
  • Release gates: CI runs Rust + webview tests on every PR; e2e before each release

D. One-liner

Wursor is the agentic workshop for WordPress — code, WP-CLI, data, and a live site in one loop.
