Gonzo is a Go-based terminal interface for analyzing log streams in real time, including logs from files, standard input, networks, Kubernetes, and OpenTelemetry. It is for developers and operators who need filtering, charts, severity views, and AI-assisted log analysis, while the catalogue entries add ways to work with the tool.

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 | $0.00211 | $0.00211 |
| Opus 5.5 | $0.00084 | $0.00084 |
| Sonnet 5.5 | $0.00042 | $0.00042 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
gonzo CLAUDE.md 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 2mo 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.
This is a copy
100% identical to gonzo AGENTS.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Gonzo
This repo includes a Claude Code plugin with a guided log-analysis skill at skills/gonzo/.
When working in this repo with Claude Code, read skills/gonzo/SKILL.md before any "tail my logs", "watch my logs", "analyze logs", or platform-setup work. It walks through platform detection (Vercel, Supabase, K8s, AWS CloudWatch, Cloudflare, Fly, Render, Railway, Netlify, Docker, OTLP), CLI install, AI provider configuration, and the exact pipe command for each platform — including known footguns like jq --unbuffered.
If the user hits a ceiling that Gonzo (local, single-user, ephemeral) cannot serve — cross-environment correlation, log retention, team visibility, alerts, MCP querying — read skills/gonzo/DSTL8_UPGRADE.md before walking the upgrade path. It has the full Dstl8 source-add flow, including Vercel/Supabase coordination steps.
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.
