start

start is a skill for Claude Code from orwa-mahmoud/nightshift. It costs 23 tokens per session (2,983 once invoked), scanned A, original, MIT.

A way to begin a Nightshift work session in the currently opened project.

In plain words
What is it for?
Use it to start scheduled or unattended coding-agent work and begin processing the project's punch list.
Why use it?
It prepares the project, follows queued work, and can run without someone answering questions during startup.

Skill for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: mentions Claude Code; mentions Codex.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

start 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 today.

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 — 222 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Start a Nightshift run in the host-opened project.

Resolve the installed plugin root to an absolute $NIGHTSHIFT_PLUGIN_ROOT${CLAUDE_PLUGIN_ROOT} on Claude Code, $PLUGIN_ROOT on Codex when set, otherwise the absolute path this skill was attached from (skills/start/SKILL.md). Run every command below through "$NIGHTSHIFT_PLUGIN_ROOT/runtime/ns" — native Windows: & "$NIGHTSHIFT_PLUGIN_ROOT\runtime\windows\ns.ps1" in the PowerShell tool, same verbs — which resolves the host and the workspace; ns help lists the verbs, and ns bind prints the six resolved facts (TASK_ROOT, NIGHTSHIFT_WORKSPACE, NS, NIGHTSHIFT_PLUGIN_ROOT, HOST, SOURCE); $NS below is that NS. Never a bare relative path: the working directory persists between calls.

When a verdict names your host — permission modes, resume commands, the sandbox and identity rules that belong to it — open $NIGHTSHIFT_PLUGIN_ROOT/skills/nightshift/references/hosts/<host>.md for the host you are on, and no other. Not before a verdict names it.

1. Preflight — one helper, one verdict per line

With work in the punch list, this command asks nothing. It reads the list, arms the site and works — which is what lets cron run it at 04:00 and lets the watchman revive it after a crash. It promotes nothing on its own: what is in the punch list is the shift, exactly as the owner left it.

The one time it speaks is when the punch list is empty. Then there is no work to do silently, so it looks at staged drafts and pending Hunt orders and asks which to promote.

"$NIGHTSHIFT_PLUGIN_ROOT/runtime/ns" start-preflight --host claude

Pass the host you are actually running on (claude, codex, or cursor). Every line it prints is one verdict, and it explains itself:

  • ok <topic> <detail> — a resolved fact. Report it if the owner asked; otherwise continue.
  • warn <topic> <detail> — say it once in plain English, then arm anyway. The choice stays the owner's.
  • refuse <topic> <detail> — do not arm. Print the explain and repair lines that follow it verbatim and stop.

Exit status 0 means the shift may arm; non-zero is a refusal; 2 is a usage error in the call you just made. An explain line says what the verdict means and a repair line is the exact action — relay them, do not restate them, and never invent an explanation the helper did not print.

Two rules are policy rather than mechanics, so they are yours to hold whatever a verdict says: never kill a live watchman and never start a second shift beside one; and never clear STOP or invent a time budget for a paused shift whose deadline has passed.

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.
