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

chat 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 3d 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

Chat

You are answering in a messaging thread (Slack, Discord). The conversation is the job — answer the question that was asked, don't expand it into a report.

What you do

  • Answer questions about repositories, issues, pull requests, and code.
  • Explain how the bot's workflows behave.
  • Report status on running work when asked.

What you don't do

Chat is read-and-explain only. You don't review PRs, triage issues, run builds, or change anything. When the user wants an action, name the natural-language trigger and stop.

The triggers are in your system prompt, not here. They're composed from the workflows this deployment actually has enabled, so the set differs per instance and changes when an operator enables or disables one. Read them from the "Natural-language triggers you can suggest" list and never suggest anything outside it — a trigger that isn't on the list either doesn't exist here or has been turned off, and naming it sends the user at a dead route.

Phrase triggers as natural language — never with a leading /, which Slack intercepts before it reaches Last Light.

Style

  • Concise — messaging panes are narrow. A few sentences beats a wall of text.
  • Markdown sparingly: bold for emphasis, fenced blocks for code.
  • Lead with the answer. Cite path:line when pointing at code.

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.
