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 | $0.00000 | $0.01563 |
| Opus 5 | $0.00000 | $0.00781 |
| Sonnet 5 | $0.00000 | $0.00313 |
| Haiku 4.5 | $0.00000 | $0.00156 |
Grade A, and why
lastlight-guide 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 5d 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 — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Last Light — where do you want to go?
You don't need to know which skill you need — describe what you want and this maps you onto it.
If the user already named a concrete task, don't linger here — hand off to the matching skill immediately (see the menu below). This guide is for "which one do I need?", not for doing the work.
There are two big things people do with Last Light:
- Operate a deployment — stand up the agent, connect to it, customize it.
- Measure its quality — run its real workflows as evals, compare models, build datasets.
If the user's goal is ambiguous, ask (use AskUserQuestion) rather than
guessing which flow they mean — "are you setting up a server, connecting a CLI to
one, customizing workflows, or running evals?" Then hand off to the skill below;
each is a full runbook, so invoke it and follow it rather than re-deriving its
steps here.
Flow 1 — operate a Last Light deployment
The route from nothing to a running, customized agent. Do these in order the first time; each is also usable on its own later.
lastlight-server— install & configure the server: Docker stack, a GitHub App, model provider key, and the repos it may manage. Start here to stand one up for the first time. Config lives in a private overlay atinstance/.lastlight-client— point thelastlightCLI at an existing server and log in (saves URL + token to~/.lastlight/config.json). For people who use a server someone else runs — no Docker, no GitHub App.lastlight-overlay— create & customize theinstance/overlay: fork built-in workflows, prompts, skills, or the agent persona (agent-context), and tuneconfig.yaml— overriding only what you name, layered over the packaged defaults. Reach for it whenever you want to change what the agent does or how it behaves on an existing deployment.lastlight-debug— inspect a running instance over its admin API (no SSH): find a failed/stuck workflow, read the phase table, tail a session transcript, search logs, read server/docker logs, trigger/pause crons, resolve approvals, check stats. Reach for it when something already deployed misbehaved and you need to see why.
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-guide is a skill published in the GitHub repository nearform/lastlight (22 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,563 tokens. 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.

Counts lines, words, and bytes in a text file using the bundled count.sh script. Use when asked to count/measure a file's size in these terms.
design-taste-frontend
Anti-slop frontend skill for landing pages, portfolios, and redesigns. The agent reads the brief, infers the right design direction, and ships interfaces that do not look templated. Real design systems when applicable, audit-first on redesigns, strict pre-flight check.
open-code-review
Performs AI-powered code review on Git changes using the ocr CLI from alibaba/open-code-review. Use when the user asks to review code, review a pull request, review staged/unstaged changes, review a commit, or compare branches for code quality issues. Produces line-level review comments and can automatically apply…

Elite website image-to-code skill for Codex. For visually important web tasks, it must first generate the design image(s) itself, deeply analyze them, then implement the website to match them as closely as possible. In Codex, it must prefer large, readable, section-specific images instead of tiny compressed boards…
