Treat the reader as a complete beginner to this repository: they have only the current working tree and the single ExecPlan file you provide. There is no memory of prior plans and no external context. + +## Process + +Steps: +1. Discovery & Orientation: map the repo, name the scope, enumerate unknowns. Capture initial Assumptions and Open Questions in the ExecPlan. +2. Question-driven Clarification: ask focused, acceptance-oriented questions grouped by plan section. Maintain the Open Questions list in the ExecPlan and pre-link each item to a Decision Log placeholder. +3. Draft the Plan: complete the ExecPlan skeleton end-to-end (Purpose, Context, Plan of Work, Validation, Idempotence, etc.), calling out risks and dependencies. +4. Resolve Questions: as answers arrive, immediately update the ExecPlan—move items from Open Questions to the Decision Log with rationale; adjust Plan of Work and Acceptance accordingly. +5. Approval Gate: present the updated ExecPlan for approval. Do not implement until approved. +6. Implementation & Validation: implement per the plan, update Progress with timestamps, and validate via tests and acceptance. Log learnings in Surprises & Discoveries. +7. Closeout: write Outcomes & Retrospective; ensure the plan remains self-contained and accurate. +8. Write your plan to the appropriate location: + - App-specific: `apps//.agents/plans/-.md` + - Package-specific: `packages//.agents/plans/-.md` + - Cross-app: `.agents/plans/-.md` + Use `` in `YYYYMMDD-HHmm` format (e.g., `20240613-1045-my-feature-plan.md`). This ensures plans are sorted from most recent to oldest. +9. Plan Lifecycle: When the plan is complete and a PR is created, move it to the `done/` folder within the same directory. If abandoned, move it to `abandoned/`. + +Example questions: +``` +I reviewed the existing auth implementation in apps/web/src/app/auth/. + +Where should the new OAuth provider live? +a) apps/web/src/lib/auth/providers/ (co-located with auth logic) +b) packages/shared/src/auth/ (shared across apps) +c) Other (specify) + +How should we handle token refresh? +a) Silent refresh via interceptor +b) Explicit refresh on 401 response +c) Other (specify) +``` + +## How to use ExecPlans and PLANS.md + +When authoring an executable specification (ExecPlan), follow this document _to the letter_. Be thorough in reading (and re-reading) source material to produce an accurate specification. When creating a spec, start from the skeleton and flesh it out as you do your research. + +When implementing an executable specification (ExecPlan), do not prompt the user for "next steps"; simply proceed to the next milestone. Keep all sections up to date, add or split entries in the list at every stopping point to affirmatively state the progress made and next steps. Resolve ambiguities autonomously, and commit frequently. + +When discussing an executable specification (ExecPlan), record decisions in a log in the spec for posterity; it should be unambiguously clear why any change to the specification was made. ExecPlans are living documents, and it should always be possible to restart from _only_ the ExecPlan and no other work. + +When researching a design with challenging requirements or significant unknowns, use milestones to implement proof of concepts, "toy implementations", etc., that allow validating whether the user's proposal is feasible. Read the source code of libraries by finding or acquiring them, research deeply, and include prototypes to guide a fuller implementation. + +## Requirements + +NON-NEGOTIABLE REQUIREMENTS: + +* Every ExecPlan must be fully self-contained. Self-contained means that in its current form it contains all knowledge and instructions needed for a novice to succeed. +* Every ExecPlan is a living document. Contributors are required to revise it as progress is made, as discoveries occur, and as design decisions are finalized. Each revision must remain fully self-contained. +* Every ExecPlan must enable a complete novice to implement the feature end-to-end without prior knowledge of this repo. +* Every ExecPlan must produce a demonstrably working behavior, not merely code changes to "meet a definition". +* Every ExecPlan must define every term of art in plain language or do not use it. + +Purpose and intent come first. Begin by explaining, in a few sentences, why the work matters from a user's perspective: what someone can do after this change that they could not do before, and how to see it working. Then guide the reader through the exact steps to achieve that outcome, including what to edit, what to run, and what they should observe. + +The agent executing your plan can list files, read files, search, run the project, and run tests. It does not know any prior context and cannot infer what you meant from earlier milestones. Repeat any assumption you rely on. Do not point to external blogs or docs; if knowledge is required, embed it in the plan itself in your own words. If an ExecPlan builds upon a prior ExecPlan and that file is checked in, incorporate it by reference. If it is not, you must include all relevant context from that plan. + +## Formatting + +Format and envelope are simple and strict. Each ExecPlan must be one single fenced code block labeled as `md` that begins and ends with triple backticks. Do not nest additional triple-backtick code fences inside; when you need to show commands, transcripts, diffs, or code, present them as indented blocks within that single fence. Use indentation for clarity rather than code fences inside an ExecPlan to avoid prematurely closing the ExecPlan's code fence. Use two newlines after every heading, use # and ## and so on, and correct syntax for ordered and unordered lists. + +When writing an ExecPlan to a Markdown (.md) file where the content of the file *is only* the single ExecPlan, you should omit the triple backticks. + +Write in plain prose. Prefer sentences over lists. Avoid checklists, tables, and long enumerations unless brevity would obscure meaning. Checklists are permitted only in the `Progress` section, where they are mandatory. Narrative sections must remain prose-first. + +## Guidelines + +Self-containment and plain language are paramount. If you introduce a phrase that is not ordinary English ("daemon", "middleware", "RPC gateway", "filter graph"), define it immediately and remind the reader how it manifests in this repository (for example, by naming the files or commands where it appears). Do not say "as defined previously" or "according to the architecture doc." Include the needed explanation here, even if you repeat yourself. + +Avoid common failure modes. Do not rely on undefined jargon. Do not describe "the letter of a feature" so narrowly that the resulting code compiles but does nothing meaningful. Do not outsource key decisions to the reader. When ambiguity exists, resolve it in the plan itself and explain why you chose that path. Err on the side of over-explaining user-visible effects and under-specifying incidental implementation details. + +Question discipline and placement: +- Keep each question atomic and acceptance-oriented (what behavior must hold? how will we observe it?). +- Record questions in an Open Questions section of the ExecPlan; tag each with the plan section it affects (e.g., Validation, Plan of Work). +- When a question is answered, create a Decision Log entry with rationale and update the affected sections. Remove the item from Open Questions. +- Prefer at most 3-7 active questions; timebox low-impact ones or convert them into explicit Assumptions. + +Anchor the plan with observable outcomes. State what the user can do after implementation, the commands to run, and the outputs they should see. Acceptance should be phrased as behavior a human can verify ("after starting the server, navigating to http://localhost:3000/health returns HTTP 200 with body OK") rather than internal attributes ("added a HealthCheck struct"). If a change is internal, explain how its impact can still be demonstrated (for example, by running tests that fail before and pass after, and by showing a scenario that uses the new behavior). + +Specify repository context explicitly. Name files with full repository-relative paths, name functions and modules precisely, and describe where new files should be created. If touching multiple areas, include a short orientation paragraph that explains how those parts fit together so a novice can navigate confidently. When running commands, show the working directory and exact command line. When outcomes depend on environment, state the assumptions and provide alternatives when reasonable. + +Be idempotent and safe. Write the steps so they can be run multiple times without causing damage or drift. If a step can fail halfway, include how to retry or adapt. If a migration or destructive operation is necessary, spell out backups or safe fallbacks. Prefer additive, testable changes that can be validated as you go. + +Validation is not optional. Include instructions to run tests, to start the system if applicable, and to observe it doing something useful. Describe comprehensive testing for any new features or capabilities. Include expected outputs and error messages so a novice can tell success from failure. Where possible, show how to prove that the change is effective beyond compilation (for example, through a small end-to-end scenario, a CLI invocation, or an HTTP request/response transcript). State the exact test commands appropriate to the project's toolchain and how to interpret their results. + +## Superset-Specific Context + +This is a Bun + Turborepo monorepo with the following structure: + +**Apps:** +- `apps/web` - Main web application (app.superset.sh) +- `apps/marketing` - Marketing site (superset.sh) +- `apps/admin` - Admin dashboard +- `apps/api` - API backend +- `apps/desktop` - Electron desktop application +- `apps/docs` - Documentation site +- `apps/cli` - CLI tooling + +**Packages:** +- `packages/ui` - Shared UI components (shadcn/ui + TailwindCSS v4) +- `packages/db` - Drizzle ORM database schema +- `packages/local-db` - Local database schema +- `packages/queries` - Shared query logic +- `packages/shared` - Shared constants and utilities +- `packages/trpc` - tRPC configuration + +**Common Commands:** +- `bun dev` - Start all dev servers +- `bun test` - Run tests +- `bun build` - Build all packages +- `bun run lint` - Check for lint issues +- `bun run lint:fix` - Fix auto-fixable lint issues +- `bun run typecheck` - Type check all packages +- `bun run db:push` - Apply schema changes +- `bun run db:migrate` - Run migrations + +Capture evidence. When your steps produce terminal output, short diffs, or logs, include them inside the single fenced block as indented examples. Keep them concise and focused on what proves success. If you need to include a patch, prefer file-scoped diffs or small excerpts that a reader can recreate by following your instructions rather than pasting large blobs. + +## Milestones + +Milestones are narrative, not bureaucracy. If you break the work into milestones, introduce each with a brief paragraph that describes the scope, what will exist at the end of the milestone that did not exist before, the commands to run, and the acceptance you expect to observe. Keep it readable as a story: goal, work, result, proof. Progress and milestones are distinct: milestones tell the story, progress tracks granular work. Both must exist. Never abbreviate a milestone merely for the sake of brevity, do not leave out details that could be crucial to a future implementation. + +Each milestone must be independently verifiable and incrementally implement the overall goal of the execution plan. + +## Living plans and design decisions + +* ExecPlans are living documents. As you make key design decisions, update the plan to record both the decision and the thinking behind it. Record all decisions in the `Decision Log` section. +* ExecPlans must contain and maintain a `Progress` section, a `Surprises & Discoveries` section, a `Decision Log`, and an `Outcomes & Retrospective` section. These are not optional. +* When you discover optimizer behavior, performance tradeoffs, unexpected bugs, or inverse/unapply semantics that shaped your approach, capture those observations in the `Surprises & Discoveries` section with short evidence snippets (test output is ideal). +* If you change course mid-implementation, document why in the `Decision Log` and reflect the implications in `Progress`. Plans are guides for the next contributor as much as checklists for you. +* At completion of a major task or the full plan, write an `Outcomes & Retrospective` entry summarizing what was achieved, what remains, and lessons learned. + +# Prototyping milestones and parallel implementations + +It is acceptable--and often encouraged--to include explicit prototyping milestones when they de-risk a larger change. Examples: adding a low-level operator to a dependency to validate feasibility, or exploring two composition orders while measuring optimizer effects. Keep prototypes additive and testable. Clearly label the scope as "prototyping"; describe how to run and observe results; and state the criteria for promoting or discarding the prototype. + +Prefer additive code changes followed by subtractions that keep tests passing. Parallel implementations (e.g., keeping an adapter alongside an older path during migration) are fine when they reduce risk or enable tests to continue passing during a large migration. Describe how to validate both paths and how to retire one safely with tests. When working with multiple new libraries or feature areas, consider creating spikes that evaluate the feasibility of these features _independently_ of one another, proving that the external library performs as expected and implements the features we need in isolation. + +## Skeleton of a Good ExecPlan + +```md +# + +This ExecPlan is a living document. The sections `Progress`, `Surprises & Discoveries`, `Decision Log`, and `Outcomes & Retrospective` must be kept up to date as work proceeds. + +## Purpose / Big Picture + +Explain in a few sentences what someone gains after this change and how they can see it working.

Every assumption must either be confirmed (moved to the Decision Log) or removed by implementation end. + +## Open Questions + +List unresolved, acceptance-oriented questions. For each, note the impacted plan sections (e.g., Validation, Plan of Work) and add a placeholder in the Decision Log for the eventual answer. + +## Progress + +Use a list with checkboxes to summarize granular steps.

Compare the result against the original purpose. + +## Context and Orientation + +Describe the current state relevant to this task as if the reader knows nothing. Name the key files and modules by full path. Define any non-obvious term you will use. Do not refer to prior plans. + +## Plan of Work + +Describe, in prose, the sequence of edits and additions. For each edit, name the file and location (function, module) and what to insert or change. Keep it concrete and minimal. + +## Concrete Steps + +State the exact commands to run and where to run them (working directory). When a command generates output, show a short expected transcript so the reader can compare. This section must be updated as work proceeds. + +## Validation and Acceptance + +Describe how to start or exercise the system and what to observe. Phrase acceptance as behavior, with specific inputs and outputs. If tests are involved, say "run `bun test` and expect passed; the new test fails before the change and passes after". + +## Idempotence and Recovery + +If steps can be repeated safely, say so. If a step is risky, provide a safe retry or rollback path. Keep the environment clean after completion. + +## Artifacts and Notes + +Include the most important transcripts, diffs, or snippets as indented examples. Keep them concise and focused on what proves success. + +## Interfaces and Dependencies + +Be prescriptive. Name the libraries, modules, and services to use and why. Specify the types, traits/interfaces, and function signatures that must exist at the end of the milestone. Prefer stable names and paths such as `packages/db/src/schema/users.ts` or `apps/web/src/lib/auth.ts`. E.g.: + +In packages/db/src/schema/users.ts, define: + + export const users = pgTable('users', { + id: text('id').primaryKey(), + email: text('email').notNull().unique(), + createdAt: timestamp('created_at').defaultNow(), + }); +``` + +If you follow the guidance above, a single, stateless agent -- or a human novice -- can read your ExecPlan from top to bottom and produce a working, observable result. That is the bar: SELF-CONTAINED, SELF-SUFFICIENT, NOVICE-GUIDING, OUTCOME-FOCUSED. + +When you revise a plan, you must ensure your changes are comprehensively reflected across all sections, including the living document sections, and you must write a note at the bottom of the plan describing the change and the reason why. ExecPlans must describe not just the what but the why for almost everything. + +## Plan Lifecycle + +ExecPlans have a defined lifecycle that keeps the `.agents/plans/` folder clean and provides a historical record of completed work. + +### Directory Structure + +``` +apps//.agents/plans/ # App-specific plans + .md + done/ + abandoned/ + +packages//.agents/plans/ # Package-specific plans + .md + done/ + abandoned/ + +.agents/plans/ # Cross-app/shared plans + .md + done/ + abandoned/ +``` + +### When to Move Plans + +**To `done/`**: Move the plan to the `done/` folder within the same directory when creating a PR that completes the work.

When terminal persistence is enabled, we now render all tabs and toggle visibility instead of unmounting. The SIGWINCH restoration logic remains as a fallback for app restart recovery when a fresh xterm instance must reattach to an existing PTY session. + +--- + +## Future Improvements + +These are documented for future work. They are not blocking for the current implementation. + +### 1. Buffer PTY Output for Hidden Terminals + +Currently, hidden terminals continue processing PTY output through xterm.js.
