respawn

respawn is a skill for Claude Code, Codex from ruben-sj/respawn-skill. It costs 141 tokens per session (2,420 once invoked), scanned A, original, MIT.

A session-resumption tool for Claude that waits through the service’s five-hour usage limit and starts the session again when access returns. It must be set up before the limit is reached and includes a period in which the user can cancel the resume.

In plain words
What is it for?
Use it for lengthy or overnight Claude sessions that may reach the five-hour limit and need to continue afterward.
Why use it?
It reduces the need to monitor a long-running session and manually restart work after a usage limit.

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

respawn 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

respawn

Gaming metaphor: the session "dies" (gets blocked by the 5-hour usage limit), waits, and respawns automatically once the window reopens.

Critical precondition: this must be set up BEFORE the account gets blocked. After a cutoff, no new message can be sent in any session until the window reopens — so there is no reactive way in. The user must invoke /respawn proactively (at the start of a heavy/long session, or when they notice they're approaching the limit).

Confirmed by repeated real-world use (multiple overnight runs, multiple sessions running /respawn in parallel, multiple consecutive windows in a single run): a recurring CronCreate job does survive repeated rate-limit rejections and fires correctly once the window reopens, the detect → notify → cancel-window → resume flow works end to end (tested with the then-fixed 5-minute cancel window), and this holds across several concurrent sessions without interference. Still not an officially supported Anthropic feature — auto-resume after a rate limit is an open, unimplemented feature request (GitHub issues anthropics/claude-code #26775 and #36320) — but the core mechanism is no longer just a working assumption.

Known limitations (tell the user this when the skill is activated, and again if they ask):

  • Requires this app/session to stay open for the entire waiting period. Believed (not independently confirmed) that CronCreate jobs are in-memory only ("session-only") and disappear without a trace if the session ends or the app is closed.
  • Jobs only fire while the session is idle. If the polling check or the cancel-window deadline lands while the user is actively interacting (or another turn is in flight), that firing is delayed or effectively skipped — this especially undermines the "resuming in N min" promise in the push notification.
  • Believed (not independently confirmed): recurring CronCreate jobs auto-expire after 7 days. Not yet tested against a wait that long — treat /respawn as covering at most a 7-day wait until this is verified.
  • Unverified actual token cost of rejected attempts while the window is closed.

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.
