visual-plan

Agent-Native Plans

Agent-Native Plans is structured visual planning mode for coding agents. Build the plan you would normally write in Markdown, but as a scannable document with editable blocks mixed in: inline diagrams, code snippets, open questions, and an optional top visual review area (wireframe canvas, live prototype, or both in tabs). Architecture and backend plans stay document-only; UI and product plans start with the top canvas/prototype (the Visual Surface Choice section owns that rule).

/visual-plan is the packaged command and main entry point. Choose the review mode from the task: UI-first when the work is primarily product UI and review should start with screens, prototype-first when review should start with a functional live prototype, design-first when review needs full-fidelity branded screens, or visual-intake when the user explicitly wants a questionnaire before planning. When a Codex, Claude Code, Markdown, or pasted plan already exists, /visual-plan uses that source plan as the starting point and builds the review surface from it instead of starting over.

When To Use

Create or adapt a visual plan when work is multi-file, ambiguous, long-running, risky, or UI-heavy, when architecture / data flow / UI direction / options / open questions would benefit from inline diagrams or structured blocks, when the user needs to react to a direction before you implement, or when an existing text plan needs a richer review surface.

Plan Discipline

• Gate hard. A polished visual plan is the most expensive plan form; only invest when a wrong direction is costly. Skip it for trivial, unambiguous work — typos, one-line fixes, a single well-specified function, anything whose diff you could describe in one sentence — and just make the change. Never pad a plan with filler and never ship a single-step plan.
• Research before you draft. Read the real files, actions, schema, and patterns first; name actual files, symbols, and data shapes instead of inventing them. Check existing actions/ before proposing endpoints and prefer named client helpers over raw fetch. Delegate wide exploration to a sub-agent. Lead with reuse: for each step, name what it reuses — existing actions, schema, components, helpers — before what it adds, so the plan explains the genuinely new delta instead of redescribing what already exists.
• Decide the hard-to-reverse bets first. For non-trivial backend, data, or API work, sketch where the feature is headed, then call out the decisions that are expensive to undo once data or callers depend on them — wire format, public ids, data-model shape, auth and ownership boundaries — and get those right in the plan even if most of the feature ships later. Then scope to the smallest first cut that proves the approach without foreclosing it, stating both what is in and what is explicitly deferred.
• Preserve existing plans. If the user pasted, referenced, or already has a Codex / Claude Code / Markdown plan, treat it as source material. Preserve its intent, do not invent codebase facts, label inferred visuals as inferred, and build the visual review structure around the plan the user already has.
• Planning is read-only. Make no source edits while building or reviewing the plan. Start editing only after the user approves the direction.
• Clarify vs. assume. Do not ask how to build it — explore and present the approach and options in the plan. Ask a clarifying question only when an ambiguity would change the design and you cannot resolve it from the code; use the host agent's normal ask-user-question flow and batch 2-4 high-leverage questions before finalizing. Do not call create-visual-questions from /visual-plan. Otherwise state the assumption explicitly and proceed, and keep anything unresolved in the plan's single bottom question-form Open Questions block.
• The plan is the approval gate. After surfacing it, ask the user to review and approve before you write code, and name which files/areas the work touches. Presenting the plan and requesting sign-off is the approval step — do not ask a separate "does this look good?" question.
• The document is the source of truth, not the chat. When scope shifts, update the plan with update-visual-plan rather than only changing course in chat, and re-read the approved plan before major steps.

Always Publish As An Agent-Native Plan — Never Inline

The deliverable is ALWAYS a published Agent-Native Plan created via the Plan MCP connector (plan server, or legacy agent-native-plans). NEVER hand the plan over as inline chat content — no Markdown prose, ASCII sketch, table, or fenced wireframe. If the connector's tools are missing, do NOT fall back to inline output: the usual cause is a connector that did not finish connecting this session (it registers zero tools), not auth. Stop and give the user the exact restore step — reconnect via /mcp (or restart the session); only if genuinely unauthenticated, run npx @agent-native/core@latest connect https://plan.agent-native.com. Publish once the tool is reachable. Local-files privacy mode (after Tool Guidance) is the only exception.

Core Workflow

1. Follow the host agent's normal planning flow: inspect the codebase, delegate wide exploration when useful, gather the info needed, and ask native clarifying questions as needed before generating the plan. If a source plan already exists, gather its exact text from the user's paste, a referenced file, or recent visible agent context; do not invent source text.
2. Call get-plan-blocks for the authoritative block catalog — do not author from memorized tags. Then call the mode-matched create tool: create-visual-plan for document-first plans (architecture, backend, data, refactor, API), create-ui-plan for UI-first plans, create-prototype-plan for prototype-first plans, create-plan-design for design-first plans, create-visual-questions only when the user explicitly asks for a visual intake questionnaire. When a source plan already exists, pass it as planText and preserve the original plan's intent while adding structured review content.
3. Compose or enrich any top UI/product visual surface and write the document with native blocks (see references/canvas.md and references/document-quality.md). Keep the document close to the Markdown plan the agent would normally output, or to the existing plan when one was provided. For non-visual plans, skip the top visual surface (Visual Surface Choice below owns the rule) and put diagram, data-model, api-endpoint, diff, file-tree, code, and annotated-code blocks directly next to the relevant prose.
4. Surface the returned Plans link or inline MCP App and ask the user to review. Always include the actual URL in chat so the next step is a click in CLI or other text-only hosts. When the host exposes an embedded browser/preview panel and a tool can open arbitrary URLs there, open the returned plan URL automatically for convenient review — a convenience and smoke test, never the only handoff or the access model. Plans should load out of the box for the local agent and local browser session; if a signed-in embedded browser cannot read a local plan that an anonymous/tool check can read, fix the app/action ownership or access path rather than patching one plan by hand. For high-stakes plans (architecture, backend, data, multi-file, or risky), also kick off the self-review pass in Self-Review Before Handoff while the user reads, instead of blocking the handoff on it.
5. Call get-plan-feedback before editing, after review, after any long pause, and before the final response. Treat anchorDetails, resolver intent, recent review events, and any focused screenshots from browser handoff as the source of truth for exactly what changed and exactly what each comment points at.
6. Apply changes with update-visual-plan, preferring targeted contentPatches. When the user wants source-control friendly edits, use patch-visual-plan-source against the MDX files instead of regenerating the plan.
7. Export with export-visual-plan only when the user wants a shareable receipt or repo-check-in artifacts.

Self-Review Before Handoff

For high-stakes plans — architecture, backend, data-model, migration, multi-file, or otherwise risky work — run one adversarial self-review pass before treating the plan as final. Skip it for small, UI-only, or single-decision plans where the cost outweighs the value. Keep the pass cheap and non-blocking:

• Surface the plan first, review concurrently. Post the link and let the user start reading, then run the review in parallel — never make the user wait on it.
• Review the written plan; do not re-research. Critique the plan text and its own blocks. The grounding was already done while drafting, so the review checks the output instead of re-exploring the repo.
• Spawn one skeptical reviewer whose only job is to find what is weak, missing, or wrong — not to praise. Point it at: hard-to-reverse decisions made implicitly or not at all (wire format, public ids, data-model shape, auth, ownership); steps not anchored in real files or symbols; a menu of options where the plan should commit to one; obvious missing decisions ("what happens when X?", "why not Y?"); and padding or single-step filler.
• Fix vs. ask. Apply clear-cut fixes yourself with update-visual-plan contentPatches — vague non-goals, unanchored claims, an obvious missing decision. Route genuine judgment calls back to the user instead: add them to the bottom question-form Open Questions block or batch them into the normal ask-user-question flow. Do not silently decide them.
• Do not surprise the user mid-read. On a large plan, apply the patches before the editor loads; otherwise note briefly that a self-review is running so the plan changing under them is expected. When you next respond, summarize what the review changed and what it surfaced for the user to decide.

Visual Surface Choice

Choose the surface before creating the plan or after reading the source plan. Do not add visual chrome by default:

• No visual surface for architecture-only, backend-only, data migration, copy-only, or otherwise non-visual plans. Do not use the top canvas for architecture diagrams, dependency maps, file plans, API contracts, or data-flow-only reviews. Use a strong document with local inline diagrams only when relationships need a visual explanation, usually one spatial diagram per recommendation or decision. Prefer grouped regions, layers, quadrants, matrices, or before/after panels over a single-axis chain unless the relationship is truly sequential.
• Canvas only for one static screen, a before/after comparison, a component state, a small popover, or a visual direction that does not require clicking. Put those wireframes in content.canvas and omit content.prototype.
• Canvas + prototype for multi-step UI flows, onboarding, wizards, review/approval flows, navigation changes, or anything where the reviewer needs to operate the behavior. Keep the static wireframes in content.canvas, add the aligned functional prototype in content.prototype, and rely on the top visual tabs to switch between them.
• Prototype-first when the user asks to operate the UI or when interaction is the main question. Use create-prototype-plan, which still preserves static mocks where useful.

For mixed canvas + prototype plans, reuse the same real labels, app statuses, and screen ids across both surfaces. The canvas is the inspectable static reference; the prototype is the interactive version of that same flow, not a separate design direction.

Wireframe quality — read references/wireframe.md

UI recap/plan wireframes must meet a strict quality bar — full-width chrome, pinned bottom bars, real product content, before/after comparability, the right surface preset, --wf-* tokens instead of hex, and no <html>/<style>/font tags. Before authoring ANY wireframe / <Screen> / WireframeBlock, READ references/wireframe.md in this skill directory — it is the single source of truth for HTML wireframe quality, shared word for word with /visual-plan and /visual-recap. Do not author wireframes from memory.

Canvas — read references/canvas.md

The canvas is the single source of truth for static UI mockups: the surface locks each artboard's footprint, mixed surfaces lay out in lanes, annotations are plain-text designer notes anchored by targetId/placement, and edits are surgical contentPatches. Before authoring or editing ANY canvas, artboard, or annotation, READ references/canvas.md in this skill directory — it is the single source of truth for canvas/artboard mechanics. Do not author canvas layouts from memory.

Document quality — read references/document-quality.md

The document is a serious technical plan, not marketing: outcome-first, prose-first, self-contained, built from the right native blocks, with open questions in a single bottom question-form and a pre-handoff visual check. Before authoring the plan document, READ references/document-quality.md in this skill directory — it is the single source of truth for the document quality bar. Do not write the document from memory.

Good vs. bad exemplar — read references/exemplar.md

For a worked example of the bar — a great UI-first plan and /visual-plan, plus the anti-patterns to avoid — READ references/exemplar.md in this skill directory before authoring a plan.

Tool Guidance

• create-visual-plan: start one structured visual plan per agent task/run, or import an existing text plan by passing planText; content may include no visual surface, canvas only, or canvas + prototype.
• create-ui-plan: start a UI-first plan when the work is primarily product UI.
• create-prototype-plan: start a prototype-first plan with a functional top review surface.
• create-plan-design: start a full-fidelity branded Design-tab plan with an optional matching Prototype tab.
• convert-visual-plan-to-prototype: convert an existing HTML wireframe canvas into a prototype plan.
• create-visual-questions: use only when the user explicitly asks for a visual intake questionnaire, not as /visual-plan preflight.
• update-visual-plan: revise content, status, or comments with targeted contentPatches (see Core Workflow step 6).
• read-visual-plan-source: read the normalized plan as plan.mdx, optional canvas.mdx, optional .plan-state.json, and JSON.
• patch-visual-plan-source: apply granular MDX AST patches by stable block, artboard, annotation, component, or wireframe-node id.
• import-visual-plan-source: create or replace a plan from an MDX folder.
• get-visual-plan: read the current structured plan, exported HTML, and annotations; it also returns the MDX folder for source workflows.
• get-plan-feedback: read unconsumed human feedback. Use it frequently; it returns grouped threads, exact anchor details, expected resolver, and recent review-event payloads so agents can act only on the comments meant for them.
• get-plan-blocks: resolve block tags before authoring — do not memorize tags; call this first to get the authoritative tag names, required fields, and prop shapes from the live block registry.
• export-visual-plan: export HTML, Markdown fallback, structured JSON, and MDX files for repo check-in.

When the user critiques a plan's look or structure, fix the renderer or this skill — never hand-edit one stored plan. Turn feedback into better guidance.

Local-Files Privacy Mode

Use local-files privacy mode when the user explicitly asks for no DB writes, no hosted Plan app, no Plan MCP publish, fully local files, offline/private planning, or when AGENT_NATIVE_PLANS_MODE=local-files is set. In this mode the plan data must never be sent to the Plan MCP server or Plan app action surface.

The local-files contract is:

• Read source context from local files and shell commands only.
• Write the plan as a local MDX folder under plans/<slug>/: plan.mdx, optional canvas.mdx, optional prototype.mdx, and optional .plan-state.json.
• Run npx @agent-native/core@latest plan local preview --dir plans/<slug> --kind plan after writing or updating the folder. Report the returned local URL or the /local-plans/<slug> route if the local Plan app is running with the same PLAN_LOCAL_DIR.
• Do not call create-visual-plan, create-ui-plan, create-prototype-plan, create-plan-design, import-visual-plan-source, update-visual-plan, patch-visual-plan-source, get-plan-feedback, export-visual-plan, or any hosted Plan tool for that plan.
• Treat feedback as file or chat feedback: update the MDX files directly, rerun the local preview command, and summarize the new local URL/path. Hosted comments, sharing, history, and publish/export receipts are unavailable until the user explicitly opts into publishing.

Local-files mode prevents plan content from going to the Agent-Native Plan database. It does not by itself make the coding agent's language model local; for that stronger privacy boundary, the host agent/model must also be local or otherwise approved by the user.

Interpreting comment anchors

get-plan-feedback returns rich anchors — read them before acting on any comment.

• Coordinate frames. targetX/targetY are percentages within the element named by targetSelector/targetKind. Bare x/y are percentages of the whole plan document. canvasX/canvasY are raw board-world pixels on the design canvas (board size given when available).
• Wireframe pins. Anchors on wireframes include targetNodeId and targetNodePath (e.g. card > list > listItem "Acme Inc") identifying the exact kit node. Use targetNodeId directly with wireframe node patch ops; use data-design-id values from design artboards with update-design-element-style. Prefer the node id/path over raw coordinates; fall back to coordinates plus the focused screenshot (red ring marks the exact point) only when no node id is present.
• Text quotes. Resolve textQuote against current prose using contextBefore/contextAfter for disambiguation. If ambiguous: true, ask the user — do not guess which occurrence is meant.
• Detached comments. get-plan-feedback flags threads whose quoted text no longer exists as detached (in detachedThreads). Reconcile these against rewritten content — never silently drop them.
• Routing. resolutionTarget is the only routing signal: act on agent, treat human as context only. @mentions are people to notify, never a routing signal.
• Two-axis state. Mark every ingested comment as consumed (consumedCommentIds on update-visual-plan). Set status=resolved only on agent-targeted comments you actually addressed; leave human-targeted comments open.

Visibility & Sharing

Use set-resource-visibility to change who can see a plan (e.g. public, login, or org-scoped). Use share-resource to grant specific users or roles access by email or role. Gate visibility before sharing any plan that covers unreleased or private work — default to the narrowest scope that meets the review need.

Setup & Authentication

There are two ways into Plans.

Coding agent (CLI). Install once with the Agent-Native CLI. The command installs the Plans skills, registers the hosted Plans MCP connector, and authenticates it in the same step (a one-time browser sign-in at setup — this is intended), so the first tool call does not hit an OAuth wall:

npx @agent-native/core@latest skills add visual-plan

After that, /visual-plan and /visual-recap are the two installed slash commands. The other planning modes (create-ui-plan, create-prototype-plan, create-plan-design, create-visual-questions) are MCP tools reachable from /visual-plan, not separate slash commands. Pass --no-connect to register the connector without authenticating, then run npx @agent-native/core@latest connect https://plan.agent-native.com whenever you are ready.

Browser (people you share with). Open the Plans editor and create & edit with no sign-up — you work as a guest. Sign in only when you want to save or share; signing in claims the plans you made as a guest into your account.

Sharing and commenting require an account: public/shared plans are viewable by anyone with the link, but commenting on them needs an agent-native account.

For fully offline, no-account use, run the Plans app locally and sync plans to your repo as MDX. This local mode is a separate advanced path, not the default hosted flow.

If a Plans tool returns needs auth, Unauthorized, or Session terminated, do not keep retrying the tool. Authenticate the connector with npx @agent-native/core@latest connect https://plan.agent-native.com (OAuth-capable hosts can instead re-run /mcp and choose Authenticate), then continue once the connector is available.

Hosted default: connect https://plan.agent-native.com/_agent-native/mcp. Do not put shared secrets in skill files.
