Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00101 | $0.00814 |
| Opus 5 | $0.00051 | $0.00407 |
| Sonnet 5 | $0.00020 | $0.00163 |
| Haiku 4.5 | $0.00010 | $0.00081 |
Grade A, and why
lastlight-client 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 6d 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Install & configure the Last Light CLI client
The lastlight CLI is a thin HTTP client: it POSTs triggers and reads a running
instance's admin API. As a client it needs only the instance URL and an auth
token, saved to ~/.lastlight/config.json (mode 0600).
1. Install the CLI
command -v lastlight >/dev/null && echo "installed" || npm i -g lastlight
2. Get the server URL
Ask the user for the instance URL (e.g. https://lastlight.example.com). If they
don't know it, they need it from whoever runs the server.
3. Log in
Two paths — pick based on environment:
-
Browser handoff (default, interactive desktop):
lastlight login https://lastlight.example.comOpens the dashboard; the user authenticates with whatever method the server has (password / Slack / GitHub OAuth) and the token is captured automatically.
-
Headless / no browser (SSH, CI, server box):
lastlight login https://lastlight.example.com --passwordPrompts for the admin password and POSTs it to
/admin/api/login. Requires the server to haveADMIN_PASSWORDset.
The token (≈7-day TTL) is saved to ~/.lastlight/config.json.
4. Verify
lastlight status
Confirm: Server healthy, Token valid. If the token shows
expired/invalid, re-run lastlight login.

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.

lastlight-client is a skill published in the GitHub repository nearform/lastlight (22 stars, last pushed yesterday), licensed MIT. It adds 101 tokens to every session and 814 once invoked, about $0.0005 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.
