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 | $0.00000 | $0.00277 |
| Opus 5 | $0.00000 | $0.00138 |
| Sonnet 5 | $0.00000 | $0.00055 |
| Haiku 4.5 | $0.00000 | $0.00028 |
Grade A, and why
_index 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.
What it actually says
+++ title = "Agents" description = "Create LLM agents from Fisk CLI applications" toc = true weight = 10 pre = "1. " +++
The main feature of Fisk AI is creating AI agents from CLI tools written with Fisk.
Any tool built with Fisk, such as the nats or choria CLI, or an application made
with Choria Application Builder, can be turned into an AI agent.
Fisk AI creates capable systems that use the abilities LLMs have, such as reasoning and text interpretation, in a safe and deterministic manner.
Building an agent resembles building a CLI tool: describe the goals, give broad guidance, supply tools to interact with the world deterministically, then run it on a shell like any other utility.
Installation
On a Mac you can install fisk-ai using homebrew:
brew tap choria-io/tap
brew install choria-io/tap/fisk-ai
Other Operating System users can download the latest release from the releases page.

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.

_index is an agent published in the GitHub repository choria-io/fisk-ai (5 stars, last pushed yesterday), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 277 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 2026-08-31.
