device-lifecycle

A command for investigating bugs in the way a device session starts, becomes ready, and shuts down. It uses the project's recorded bug history and rules for session identifiers.

In plain words
What is it for?
Use it with an issue number, a symptom description, or an audit area such as shutdown. It helps find defects involving device startup, session IDs, readiness, shutdown, daemons, or competing sessions.
Why use it?
It helps avoid repeating past mistakes and narrows lifecycle failures to the relevant session or daemon behavior. It also checks for known environment problems before deeper diagnosis.

Made for: Claude Code.

Per session 37 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 507 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

device-lifecycle 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.

What it actually says

Load and follow the device-session-lifecycle skill (skills/device-session-lifecycle/SKILL.md) — it is the source of truth for the identifiers, invariants, recurring bug classes, weak-spot map, and test discipline. Its references/history.md catalogs every past lifecycle issue/PR by era and bug class.

Input

$ARGUMENTS is one of:

  • An issue number — read it with gh issue view, classify the symptom against the skill's bug classes, check the history catalog for a prior instance, then hunt per the skill's procedure (§4).
  • A symptom description — same, starting from the identifier classification step (§1): which of the four identifiers is involved?
  • audit <area> (e.g. audit shutdown, audit registry retire paths) — sweep the named area's weak spots (§6) for violations of the invariants (§2), following the audit style of Era 4 (coded findings, one issue per confirmed defect).
  • Empty — ask what to hunt, offering the open threads listed at the end of the skill as candidates.

Rules

  • Before diagnosing, rule out the documented environment artifacts (skill §4.2): daemon-restart transport wedge, multi-worktree daemon churn, DisconnectMonitor auto-restart, stale dist behind a fresh version string.
  • Ground every claim in adb/simctl/process-table/daemon-log evidence, never a tool's success flag.
  • A fix is not done until a unit test forces the exact interleaving via the injected seams (FakeTimer/FakeIdGenerator/fakes), and — for anything touching pool runtime identity or streaming — a live-emulator or stream-subscriber check has run (skill §7 blind spots).
  • File issues / open PRs per repo conventions (skills/ship-issue, skills/push-pr) when the user asks for fixes to land.
Changes

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.

device-lifecycle is a command published in the GitHub repository kaeawc/auto-mobile (45 stars, last pushed 2d ago), licensed Apache-2.0. It adds 37 tokens to every session and 507 once invoked, about $0.0002 per session on Opus 5. 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.
