Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00019 | $0.00476 |
| Opus 5 | $0.00010 | $0.00238 |
| Sonnet 5 | $0.00004 | $0.00095 |
| Haiku 4.5 | $0.00002 | $0.00048 |
Grade A, and why
purge 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
Remove Nightshift from this project. This deletes punch lists, rules, receipts, archives, and
history under the project's .nightshift/ directory. It does not uninstall the global Nightshift
plugin.
Resolve the installed plugin root to an absolute $NIGHTSHIFT_PLUGIN_ROOT — ${CLAUDE_PLUGIN_ROOT}
on Claude Code, $PLUGIN_ROOT on Codex when set, otherwise the absolute path this skill was
attached from (skills/purge/SKILL.md). Run every command below through
"$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.
Print the exact canonical $NS path. Warn that punch lists, rules, receipts, archives, and history
will be lost, and that the plugin itself stays installed. Do not run the helper until the owner
confirms that exact path. Then:
"$NIGHTSHIFT_PLUGIN_ROOT/runtime/ns" purge-workspace \
--confirm-path "$NS"
The helper first performs Reset, then deletes only that validated .nightshift/ directory and a
local .nightshift-link on the opened task root when present. It refuses symlinks, malformed
links, workspace roots, home directories, /, and other broad paths. It never deletes repository
files outside that Nightshift state. A second Purge with the same confirmation is safe.
If the task root is linked, pass the folder you opened as --project "$TASK_ROOT". This is the
one command whose target is the task root rather than the workspace, so it is the one place the
dispatcher's answer is not the one you want: purging only the workspace path leaves the host link
in place.
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.

purge is a skill published in the GitHub repository orwa-mahmoud/nightshift (58 stars, last pushed today), licensed MIT. It adds 19 tokens to every session and 476 once invoked, about $0.0001 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.
