CrabCode on the Web (Remote Tasks)

Push long-running work — multi-agent planning, deep review — to the cloud. Your terminal stays free.

What it is

CrabCode on the Web runs cloud sessions on acosmi.com. From your local terminal you type /ultraplan or /ultrareview and CrabCode packages your current branch / PR context, ships it to the cloud, and a fleet of agents does deep planning or review. You track the remote session from your local terminal but the heavy lifting happens on acosmi.com.

Good for: long-horizon, multi-file plans and deep PR reviews — work that would otherwise pin your terminal for many minutes.

Remote command comparison

Command	Purpose	Runs where	Multi-agent	Typical duration	Subscription required	How results flow back
`/review [<PR#>]`	PR / branch baseline review	Local	No	Seconds to minutes	No	Rendered inline in the current conversation
`/ultrareview`	Deep review with broader coverage	Cloud	Yes	Minutes	Yes (token-billed)	Remote session link + pull-back to local
`/security-review`	Security audit, vulnerability report	Local (via sub-tasks)	Yes (local subagents)	Seconds to minutes	No	Markdown report inline
`/ultraplan <prompt>`	Multi-agent cloud planning	Cloud	Yes	Up to 30 minutes by default	Yes (token-billed)	Continue executing in the cloud, or pull back to local

See code-review and plan-mode for the details.

Commands in depth

`/review [<PR#>]`

Local branch / PR review (baseline). Without an argument it lists open PRs in the current repo; with a PR number it fetches the diff and writes the review.

Runs entirely locally and reuses the main conversation model
No extra remote quota used
Best for quick PR sign-offs

`/ultraplan <task>`

Multi-agent cloud planning using the strongest model. Uploads project context plus your description; a team of agents converges on a plan.

Your terminal stays free for other work
When the plan is ready you can keep executing it in the cloud session, or pull it back into the local terminal
Default timeout is 30 minutes
Requires you to have signed in via /login
Cannot be auto-triggered from a prompt — you must run it explicitly

`/ultrareview`

Heavier review backed by CrabCode on the Web. Multi-agent, runs in the cloud.

Covers more than /review: cross-file dependencies, latent regressions, style consistency, etc.
Availability depends on subscription and entitlements — you'll see an upgrade prompt when it's not enabled
Cloud sessions can be pulled back to your local terminal

`/security-review`

Runs a security audit against the changes pending on your current branch. Local by default, but internally it fans out into multiple sub-tasks for vulnerability identification and false-positive filtering.

Outputs a markdown vulnerability report (file / line / severity / exploit scenario / fix recommendation)
Only high-confidence findings (≥0.8) are reported to keep noise down
Does not upload to acosmi.com — no extra cost

Example flow

shell

> /ultraplan migrate the auth module from session cookies to JWT, with tests and a migration script

Packaging context… uploaded
Starting remote plan… session URL: https://acosmi.com/code/...
[Terminal is free; carry on with other work]

[Several minutes later]
Plan ready. Continue executing in the cloud, or pull back to local?

Billing

Remote tasks (/ultraplan / /ultrareview) are billed by token (thinking + output included) against your acosmi.com balance or subscription
Local tasks (/review / /security-review) use the main conversation model and roll up into the local /cost
See costs for details

Privacy

Starting a remote task uploads the current context (your prompt plus relevant project files) to acosmi.com
Result links are hosted on acosmi.com and gated to your account
Use with care on sensitive repos; organisations on Zero Data Retention (ZDR) get extra guarantees — see data-usage
/security-review is local; it's safer to use on code that touches secrets or credentials

Limits and caveats

Subscription / balance required — an estimate is shown before a remote command starts; you can cancel
Outbound access to acosmi.com required (remote commands only)
Cannot be auto-triggered from a prompt — you have to run /ultraplan / /ultrareview on purpose; anti-abuse measure
Remote sessions can be pulled back — use teleport to bring a cloud session into your current terminal
/security-review is a local command — it doesn't burn remote quota but still consumes tokens and time in the main conversation
