## Using it

<AccordionGroup>
  <Accordion title="Do I have to write anything myself?">
    No, and you are not meant to. Your agent captures as the work happens. If you find yourself
    maintaining Contextaco by hand, something has gone wrong — the whole point is that you do not
    keep a second system.
  </Accordion>

  <Accordion title="Is there an API or an SDK?">
    There is one interface: MCP. No SDK, no library, nothing to install. That is deliberate — the
    consumer of this is an agent, and agents already speak MCP.
  </Accordion>

  <Accordion title="Does Contextaco use my content to run a model?">
    It makes no model calls of its own. It stores and serves; your agent does the reasoning.
  </Accordion>

  <Accordion title="What format is my content in? Can I get it out?">
    Markdown, under handles, referencing each other by handle. There is nothing to export because
    there is nothing proprietary to export from — what you read is what is stored.
  </Accordion>

## Privacy and sharing

<AccordionGroup>
  <Accordion title="Is my work private?">
    Yes, by default. Publishing is an explicit act, never a side effect.
  </Accordion>

  <Accordion title="Who can see a published taco?">
    Anyone, with no account needed — including forking it. That is the point of publishing; treat it
    as irreversible in practice, because a fork someone else made stays theirs.
  </Accordion>

  <Accordion title="If someone forks my work, do they get my private notes?">
    A fork copies what the person forking can already read. Publishing decides what is readable.
  </Accordion>

  <Accordion title="Can I delete something?">
    Notes can be deleted, but content that already has checkpointed history keeps that history —
    that is what makes the record trustworthy. Files are different: deleting one is permanent and
    immediate, which is what makes storage reclaimable.
  </Accordion>
</AccordionGroup>

## Behaviour that surprises people

<AccordionGroup>
  <Accordion title="Why did my agent's write get rejected?">
    Because someone changed that content after your agent read it. You get the current content and a
    diff back, so the change can be redone on top rather than silently overwriting. See
    [Troubleshooting](/troubleshooting).
  </Accordion>

  <Accordion title="Why is a private taco 'not found' instead of 'forbidden'?">
    Because *forbidden* would confirm it exists. Not found is the honest answer to someone who is
    not entitled to know either way.
  </Accordion>

  <Accordion title="Why can't my agent change my handle?">
    It is the first half of every address you have published, and it is chosen once. An agent that
    could set it could permanently settle something only you should settle. Display name and bio are
    changeable and an agent can update them.
  </Accordion>

  <Accordion title="Why is there no merge?">
    Forking exists because an intention diverged. Merging would collapse two lines of work that
    diverged for a reason, and quietly pick a winner. Reading across a family and reporting where
    they disagree is a different operation, and a better one.
  </Accordion>

  <Accordion title="Why doesn't the taco list show every note's content?">
    Reading a taco returns its shape — metadata, the overview, and a map of notes — not every body.
    An agent's context window is the scarce resource, so bodies are fetched only when needed.
  </Accordion>
</AccordionGroup>

## Limits and cost

<AccordionGroup>
  <Accordion title="What does it cost?">
    There is one free plan. See [pricing](https://contextaco.com/pricing).
  </Accordion>

  <Accordion title="What happens when I hit the storage ceiling?">
    Writes stop; reads never do. Nothing you published becomes unreadable, and nobody loses access
    to work you shared.
  </Accordion>

  <Accordion title="How many tacos can I have?">
    Unlimited, public or private, along with unlimited agents and tokens. Storage is the only
    ceiling.
