pool

Commands for managing ready pools in Crabbox, where already-prepared remote computing environments wait to be borrowed. Borrowing marks one busy, and returning it makes it ready again or releases it.

In plain words
What is it for?
Use them to list, register, borrow, monitor, return, or maintain ready environments, including setting minimum and maximum pool sizes.
Why use it?
They reduce the wait for creating and preparing remote environments by keeping a supply available. Heartbeats and borrow tokens help track active use.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pool scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

pool

crabbox pool contains machine-pool helpers. pool list keeps the older machine inventory alias. Ready-pool subcommands manage hydrated broker leases that can be borrowed by crabbox run --pool.

Ready Pools

Ready pools are broker records for already hydrated leases. The CLI registers a lease after prewarm or actions hydrate has prepared it. Borrow marks one ready entry busy. Return either makes it ready again or drains and releases it. Manual returns for busy leases must pass the token printed by pool borrow. crabbox run --pool negotiates heartbeat enforcement and sends heartbeats automatically. Manual and older-client borrows remain deadline-free unless they send pool heartbeat; the first successful heartbeat opts that borrow in. An opted-in abandoned borrow is quarantined and cannot become ready again without being drained.

Subcommands

pool list                 list provider machine inventory
pool ready [key]          list ready-pool entries
pool identity <key>       generate an identity from an existing AWS image-backed lease
pool register <key>       register a hydrated lease
pool borrow <key>         borrow one ready lease
pool heartbeat <key>      refresh a borrowed lease deadline
pool return <key>         return, drain, or release a borrowed lease
pool ensure <key>         reconcile desired ready capacity

pool ensure persists --min-ready and --max-ready with the coordinator. With --create, each keeper first obtains an atomic fill claim, then forwards arguments after -- to prewarm. Concurrent keepers count active claims toward the maximum, so they cannot double-provision the same missing slot. An issued claim remains valid until registration, explicit release, or expiry; later policy or capacity changes block new claims but never revoke in-flight provisioning. pool ensure succeeds only when the actual ready count reaches --min-ready. Another keeper's in-flight claim is reported but does not make the command succeed. Forwarded --repo and --ref overrides are rejected; set the desired repository/ref in config before ensuring the pool.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

pool is a command published in the GitHub repository openclaw/crabbox (1,343 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,213 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
