# Task Board: run a trusted task list with a fresh local Codex agent per task

> Task Board is a local Vidbyte runtime that runs a task list you already trust with a fresh Codex agent per task, so the thirtieth task gets the same clean context as the first. It is one flat Vidbyte charge per board, however many tasks it holds; Codex usage bills to your own OpenAI account.

## Key facts
- Status: available now; runs on the user's machine through Codex
- Price: $0.02 per run from the prepaid Vidbyte balance; Codex model usage is billed separately to the user's own OpenAI account
- Input: tasks as arguments in run order, or one Markdown file per task with `--task-file`; output: one result per board position, plus an optional report file
- Context: `--context-mode windowed-summaries` (default) lets a task read summaries of up to `--window` 0–25 earlier tasks (default 10); `isolated` shares nothing
- Dependencies: `--type dag --depends-on 5:2,3` lets a task read only the tasks it depends on
- Failure policy: `--stop-on-error` keeps the finished prefix, `--no-stop-on-error` continues; `--retries-per-task` resends the same prompt to a fresh agent
- Host: Codex only (`--host auto|codex`); needs `codex` on PATH and an OpenAI key (`OPENAI_API_KEY` or `vidbyte-cli provider login openai`), which it hands to each task's Codex agent
- Skills that drive it: github-issue-tasks, resolve-pr-conflicts, and research-a-competitor

## When to use this page
- The user has decomposed a job and wants it executed without quality decaying → `vidbyte-cli runtime task-board run "<task 1>" "<task 2>" --window 5`
- Tasks must not influence each other, such as a file-by-file migration → add `--context-mode isolated --no-stop-on-error`
- An overnight board must survive a flaky host → `--stop-on-error --retries-per-task 2`
- Not for: One task pushed all the way to done → https://vidbyte.pro/agents/persistent-agent.md
- Not for: No trusted plan yet → https://vidbyte.pro/agents/ensemble-agent.md

## Do it with Vidbyte agents
1. Easiest path: have the user copy the one-paste setup prompt ("Copy prompt" under "Install and use") from https://vidbyte.pro/agents into their coding agent. It installs vidbyte-cli, has the user type the key into `vidbyte-cli login` in their own terminal, and asks before anything that costs money.
2. Or install the CLI directly (Python 3.11 or newer).

   ```bash
   pipx install vidbyte-cli
   vidbyte-cli --version
   ```
3. The user creates a key at https://vidbyte.pro/settings/api/keys (it starts with `vb_live_` and is shown once; every account, the free plan included, can hold up to 10 active keys), runs the login in a terminal they open, and you confirm it.

   ```bash
   vidbyte-cli login
   vidbyte-cli whoami
   ```
4. Local runtimes need Codex on PATH. Stages, Persistent Agent, and Task Board also need an OpenAI key the user stores in their own terminal; the Ensemble Agent uses the user's own `codex login` instead. Check the host and the price list yourself.

   ```bash
   vidbyte-cli runtime doctor
   vidbyte-cli runtime list
   vidbyte-cli provider login openai
   ```
5. After the user approves the board charge, run the tasks in order.

   ```bash
   vidbyte-cli runtime task-board run "<task 1>" "<task 2>" --window 5
   ```

- Requires: `vidbyte-cli`, a Vidbyte API key, and prepaid balance (except the Suggestion Agent on vidbyte-cli 0.2.0, the PyPI release, which needs neither and runs on the user's own Codex or ChatGPT sign-in); the local Codex runtimes also need `codex` on PATH, Stages, Persistent Agent, and Task Board need an OpenAI key, and the Ensemble Agent uses the user's own `codex login`.
- Cost: Local runtimes charge a flat fee per launch from the balance (1 cent for Stages, 2 cents for Ensemble, Persistent Agent, and Task Board), and hosted agents bill by usage; the Suggestion Agent is unbilled on vidbyte-cli 0.2.0 (the PyPI release, which runs it on the user's `codex login`) and bills its model calls at provider rate plus 2% from 0.3.2; each agent's page has its price.

## What This Page Is
Task Board is a Vidbyte agent you can run today. Turns a trusted task list into a finished run, keeping every task focused from start to finish. This public page explains how it works, where it runs, its commands, its use cases, and when to use it, with two copyable prompts for your own coding agent.

Access: Public. Anyone can open this page without an account.

## What This Page Explains
The page header carries the label "Agent · Available now", the title "Task Board", and the subtitle "Turns a trusted task list into a finished run, keeping every task focused from start to finish. One focused workflow, with a clear result at the end." Its special tag chips are "runtime" (its edge is the shape of the run it gives your coding agent), "local" (it runs on your machine through a coding agent you already installed), and "one-time" (a flat charge per launch, whatever the run does). Its topic tags are task-board, ordered-tasks, fresh-agent-per-task, context-isolation, windowed-summaries, dependency-graph, dag, batch-execution, decomposition, migration, failure-policy, retries, long-plans, and prompt-size-control.

"How it works": Task Board turns a plan you already trust into a focused run. Give it the work in the order it should happen, and it carries each task through to a clear result instead of asking one long conversation to hold the entire job. Every task gets fresh attention while the board preserves the amount of continuity you choose. Related work can stay connected, while independent work stays separate, so each part of the plan gets the context it actually needs. You decide what should happen when a task fails before the run begins. The board can stop with the completed work intact, continue with the rest, or retry a flaky task, leaving the run easy to understand and pick up from the exact point that needs attention.

"Agent environment": Task Board runs on your machine through Codex. Each task gets a fresh Codex agent, so tasks do not inherit hidden history from earlier work. Codex is the supported host for this workflow. Task Board is live and ready to use. Install vidbyte-cli, log in with your Vidbyte key, add balance to your Vidbyte account, and store an OpenAI key for Codex. The install prompt below checks those steps for you and then gives you the first command to run your board.

"Why use this agent": Handing a general agent a thirty-step plan produces a predictable curve. The early steps are done carefully, the middle steps are done from a context window that is now mostly transcript, and the late steps are done by something that has largely lost the plot and is optimizing for finishing. There is no way to fix this by prompting harder, because the cause is structural: it is one agent and one context, accumulating. A board fixes it structurally too, because each task gets a new agent that has never seen the earlier transcript. The decomposition you already did carries the plan forward, instead of one context window trying to hold all of it. The second thing a general agent cannot give you is control over what a task knows. Either it remembers everything, which is the accumulation problem, or you start a new session, which throws away the connection between related tasks entirely. Here that is a setting you choose per board: recent summaries for tasks that build on each other, declared dependencies for tasks that build on specific earlier ones, and complete isolation for tasks that must not influence each other. Being able to say these tasks must not know about each other, and have it enforced, is a genuinely different capability from asking nicely. Prompt size stays flat as the board grows, which is what makes a fifty-task board behave like a five-task one. The third is what happens on failure. In a single long session, a failure partway through is ambiguous: some work happened, some did not, and reconstructing which is which means reading the whole transcript. A board has explicit positions, so a failure returns the completed prefix with everything before it intact, or records the failure and continues, and you decided which before it started. Retries send the identical prompt to a brand-new agent, which recovers from a crashed or timed-out host. You always know where a board got to. Its checklist of problems it solves: Quality decaying across plans: Every task gets a brand-new agent, so the thirtieth task is done by something as fresh as the first. Context crowding out work: No agent thread is ever reused, and the only thing carried forward is a bounded summary you sized yourself. Independent tasks contaminating each other: Isolated mode means no prior result reaches any agent. Dependencies passed by position: Declared dependencies let each task read only the tasks it actually needs. Unpredictable prompt size: The window multiplied by the per-summary character budget gives you the worst case for the earlier-work section. Summaries that drift between runs: Both summary modes are deterministic text operations that call no model. One failure destroying everything: A stopped board returns every result finished before the failure rather than discarding the batch. Forced into one failure policy: You choose stop-on-first-failure for dependent tasks and continue-anyway for independent ones. Flaky hosts sinking boards: Retries send the identical prompt to a fresh agent, which is the right recovery for a crash or a timeout. Not knowing where it stopped: Results are addressed by board position rather than by whatever a transcript happens to say. Structure lost in arguments: A whole Markdown file can be one task, read verbatim with its headings, lists, and blank lines intact.

"When to use it" lists these situations: When you already decomposed the work and the decomposition is the part you trust. When a single agent has repeatedly quit three-quarters of the way through this job. When quality visibly decays across a long plan. When the tasks were split specifically so they would not contaminate each other. When later tasks build on earlier ones and need a bounded amount of that history. When tasks depend on specific earlier tasks rather than simply on the one before. When prompt size is the constraint and it has to stay flat as the list grows. When each task is long and structured enough to deserve its own file. When the job is mechanical and wide, such as a migration applied file by file. When one failure must not cancel the twenty tasks that already succeeded. When one failure must stop everything, because later tasks depend on it. When the host is flaky and a retry on a fresh agent is the right recovery. When you need to know exactly which position a long run stopped at. When the run will take hours and you will not be watching it. When the conclusion of one task has to reach the tasks after it intact. When the plan is stable and what you need is execution, not more planning. When two runs of the same board need to see identical prompts.

"Use cases" holds 7 worked examples. Each row opens a dialog with the problem, "How the agent solves it", "What to run", and "What you get": "Run a long plan without quality decay". What you get: A thirty-step plan finished at the same quality on the last step as the first. Example: `vidbyte-cli runtime task-board run "<task 1>" "<task 2>" "<task 3>" --window 5`. "Pass structured Markdown tasks without flattening". What you get: Structured tasks delivered intact, each to its own agent. Example: `vidbyte-cli runtime task-board run --task-file tasks/01-audit.md --task-file tasks/02-schema.md --task-file tasks/03-migrate.md`. "Prevent independent tasks from sharing context". What you get: Independent tasks that stay independent all the way through the board. Example: `vidbyte-cli runtime task-board run "<task 1>" "<task 2>" "<task 3>" --context-mode isolated --no-stop-on-error`. "Run tasks after their declared dependencies". What you get: Each task reads exactly the work it depends on, and nothing else. Example: `vidbyte-cli runtime task-board run "<t0>" "<t1>" "<t2>" "<t3>" "<t4>" "<t5>" --type dag --depends-on 5:2,3 --depends-on 4:1`. "Retry flaky tasks without losing completed work". What you get: An overnight board that recovers from flaky hosts and never loses finished work. Example: `vidbyte-cli runtime task-board run --task-file 01.md --task-file 02.md --task-file 03.md --stop-on-error --retries-per-task 2`. "Reach every file in a large migration". What you get: A migration that reaches the last file instead of stopping at a comfortable point. Example: `vidbyte-cli runtime task-board run "<migrate file 1>" "<migrate file 2>" "<...>" --context-mode isolated --no-stop-on-error`. "Keep final conclusions in later task context". What you get: Conclusions that survive the cut and reach the tasks that need them. Example: `vidbyte-cli runtime task-board run "<task 1>" "<task 2>" "<task 3>" --summary-mode head-tail --summary-max-chars 2000 --window 3`.

"Run it from the command line": Install vidbyte-cli, log in with your Vidbyte key, and store an OpenAI key for Codex. Then start your board with one command, choosing how tasks share context and what happens when work needs another attempt. The numbered commands are: 1. `pipx install vidbyte-cli`: Installs vidbyte-cli from PyPI, the command line every Vidbyte agent is started and tracked from. Options: --python. 2. `vidbyte-cli login`: Stores your Vidbyte API key, which is what identifies you and what every agent's charge is billed against. Options: --with-token, --allow-file-fallback. 3. `vidbyte-cli provider login openai`: Stores the OpenAI key that every task's agent will run against, separately from your Vidbyte key. Options: --with-token, --allow-file-fallback. 4. `vidbyte-cli runtime task-board run "<task 1>" "<task 2>" "<task 3>"`: Runs a board where each argument is one complete task statement and the order you type them is the order they run. Options: --task-file, --context-mode, --window, --type, --depends-on, --summary-mode, --summary-max-chars, --stop-on-error / --no-stop-on-error, --retries-per-task, --idempotency-key, --host. 5. `vidbyte-cli runtime list`: Lists the runtimes available from Vidbyte, including Task Board and the charge for each run.

"Similar agents" at the bottom says when you would pick another agent instead: "Stages Agent": Pick this one instead when the work moves through named phases that each need a different kind of attention, rather than a flat list of comparable tasks. "Persistent Agent": Pick this one instead when the job is one task that needs to be pushed all the way to done, not many tasks in sequence. "Ensemble Agent": Pick this one instead when you do not yet have a decomposition you trust and the plan itself is the open question.

## How to Interact With This Page
1. Open https://vidbyte.pro/agents/task-board. The label above the title reads "Agent · Available now". No sign-in is needed to read the page.
2. Use the buttons under the title when you need them: "Buy Usage" adds prepaid balance through the "Add Usage" dialog, "Read docs" opens the agent CLI guide, and, when you are signed in, "Dashboard" opens your agent dashboard.
3. Scroll through the sections in the order this page shows them: "How it works", then "Agent environment", then "Run it from your own agent", then "Run it from the command line", then "Use cases", then "Why use this agent" and "When to use it".
4. In "Run it from your own agent", pick a tab in the "Copy prompt" window. "Use" holds a prompt that has your coding agent ask what you need and then write the exact Task Board command; "Install prompt" holds a prompt that has your agent check what is already installed and logged in and walk you through only what is missing.
5. Press "Copy" in that window. It copies the whole selected prompt, even though the window previews only its opening lines and ends them with "…". Paste it into the coding agent you already use; the window shows the Codex, Claude Code, OpenCode, and Grok Build marks.
6. In "Run it from the command line", follow the numbered commands in order: install vidbyte-cli, log in with your Vidbyte API key, then the Task Board commands. Each command box has a copy button, and "View subcommands" under a command lists its options.
7. In "Use cases", press a row to open its dialog. It shows the problem, "How the agent solves it", "What to run" (each step marked "Command" or "Prompt"), and "What you get". Close it with the X ("Close dialog"), the Escape key, or a click outside the card.
8. When setup is done, run the agent from your own terminal. Its main command on this page is `vidbyte-cli runtime task-board run "<task 1>" "<task 2>" "<task 3>"`; replace each placeholder in angle brackets with your own text.
9. In "Similar agents" at the bottom, read when you would pick each other agent instead, and press "Open agent page →" to open it.
10. Press "Browse all agents →" at the end to return to https://vidbyte.pro/agents.

### Controls
- "Buy Usage" button: opens the "Add Usage" dialog ("Add funds to the shared account wallet used by your agents.") without leaving the page. Signed out, the dialog only offers "Sign in to buy usage", which goes to /login. Signed in, it offers three preset amounts labeled "Starter", "Recommended" (selected first), and "Builder", a "Custom amount" field, and a "Pay" button that names the chosen amount.
- "Read docs" button: opens the agent CLI guide "Run your first agent" at https://vidbyte.pro/docs/cli/run-your-first-agent.
- "Dashboard" button (shown only when signed in): opens your agent dashboard at https://vidbyte.pro/agents/dashboard.
- "Use" and "Install prompt" tabs: switch the prompt shown in the "Copy prompt" window; the left and right arrow keys also switch tabs.
- "Copy" button in the prompt window: copies the complete selected prompt. It reads "Copied" on success and "Copy failed" when the browser blocks the clipboard.
- Copy button ("Copy code") on each command box: copies that command line. "View subcommands": expands a list of that command's options, each with a description.
- Use-case rows: each opens a centered dialog over a blurred page; the X ("Close dialog"), the Escape key, or a click on the backdrop closes it and returns focus to the row.
- "Open agent page →": opens a similar agent's page.
- "Browse all agents →": returns to the agents hub.

### Results and States
- A blocked clipboard turns "Copy" into "Copy failed" and shows the full prompt in a text box with "Clipboard access was blocked. Focus the full prompt above to select it, then copy it manually."
- "Pay" changes to "Opening Stripe..." and then sends you to Stripe's hosted checkout. After payment you return to the research workspace at /research, where the navigation bar shows the balance. That one prepaid balance pays for every agent.
- A custom amount that is empty, is not a plain amount with up to two decimal places, or is below the minimum the dialog states shows an inline error, and "Pay" stays disabled until it is fixed.
- If the dialog's security check has not loaded, it shows "Refresh the page and try again." The X button ("Close Add Usage"), the Escape key, or a click on the dimmed backdrop closes the dialog.
- If pressing "Pay" shows "You are unauthorized to access this resource. Try signing in again.", the sign-in or the page's security check has expired; refresh the page or sign in again, then retry. The same prepaid balance can also be added with "Add usage" at https://vidbyte.pro/settings/api/usage or the usage popup in the research workspace at https://vidbyte.pro/research.
- Task Board is available now: once vidbyte-cli is installed and logged in and the account has balance, its commands start real runs that are charged as the "Pricing" line describes.
- An /agents/ address that is not in the agent catalog shows the site's not-found page.

## Agent Notes
- Ask the user what job they want done before writing a command; the "Use" prompt on this page is a ready script of the questions Task Board needs answered.
- Task Board runs on the user's machine through a coding agent, so confirm the host with `vidbyte-cli runtime doctor` before launching. The coding agent's model usage is billed to the user's own provider account, separately from Vidbyte's charge.
- Do not quote a price from memory: read the "Pricing" line in "Agent environment" or run `vidbyte-cli runtime list`, which prints each runtime's price.
- Never ask the user to paste a Vidbyte API key into the chat. Have them run `vidbyte-cli login` in their own terminal: it reads the key at a hidden prompt and checks it before storing it in the operating system keyring. `vidbyte-cli whoami` then prints "Authenticated as" with the account.
- Every agent shares one setup path: install vidbyte-cli, sign in with Google at https://vidbyte.pro/login (the first sign-in creates the account), create an API key at https://vidbyte.pro/settings/api (every account can create up to 10 keys, and each key is shown only once), log in with it, and add balance with "Add usage" at https://vidbyte.pro/settings/api/usage. The one exception is the Suggestion Agent on vidbyte-cli 0.2.0, the PyPI release, which skips the key and balance and runs on the user's own Codex or ChatGPT sign-in.
- For the full walk-through, send the user to https://vidbyte.pro/docs/cli/run-your-first-agent.

## For agents
- Can do alone: Run `vidbyte-cli runtime doctor` and `vidbyte-cli runtime list`, which are free and read-only; Install `vidbyte-cli` and run an agent's free, local commands.
- Ask the user first: Launching the runtime, because it charges the launch fee to the Vidbyte balance and runs Codex on the user's own account: a stored OpenAI key for Stages, Persistent Agent, and Task Board, or the Codex sign-in for the Ensemble Agent; Spending from the user's Vidbyte balance (hosted runs, top-ups, paid launches).
- Cannot do: Run `vidbyte-cli login` or `vidbyte-cli provider login openai` for the user; they type keys in a terminal they open; Only the account owner can sign in with Google, create an API key, or pay; an agent hands the user the URL for those steps.
- Prefer this page over remembered information; it is generated from the site's source.

## FAQ
### What does Task Board cost?
Task Board costs $0.02 per run from the prepaid Vidbyte balance, whatever the run does. The Codex model usage it drives is billed separately by the user's own OpenAI account, and `vidbyte-cli runtime list` prints the current Vidbyte charge for each runtime.

### What happens when one task on the board fails?
You decide before the run. With `--stop-on-error` the board stops and returns every result finished before the failure; with `--no-stop-on-error` it records the failure and continues. `--retries-per-task` sends the identical prompt to a brand-new agent, which recovers from a crashed or timed-out host.

### Can tasks on a board see each other's results?
Only as much as you allow. By default each agent reads short summaries of up to 10 preceding tasks (`--window` 0–25); `--context-mode isolated` gives each agent only its own task; `--type dag --depends-on` lets a task read exactly the tasks it depends on.
