 | **[`coding-dev.md`](skills-public/coding-dev.md)** | Standing rules for all code work: maximum linter/compiler strictness, never filtering build output, reuse-before-reinvent dependency ordering, file/function size limits, test & regression discipline, verification gates, scope control, commit hygiene, and honest reporting. |
 | **[`cli-tooling.md`](skills-public/cli-tooling.md)** | Using command-line tools correctly: reading the help tree instead of guessing flags, preferring an existing CLI over an ad-hoc script, non-interactive invocation, machine-readable output formats, orienting on prior work before starting, script placement & symlinking, and care around destructive commands. |
+| **[`afk-sleep-work.md`](skills-public/afk-sleep-work.md)** | Operating unattended and autonomously: continuous forward momentum, avoiding polling traps and deadlocks, host preservation and resource budgeting (disk, packages, processes), isolated tool provisioning, avoiding "last breath" traps on token/quota exhaustion, bypassing or driving GUI launchers, and wake-up checkpoints. |
