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 | $0.01603 | $0.01603 |
| Opus 5.5 | $0.00641 | $0.00641 |
| Sonnet 5.5 | $0.00321 | $0.00321 |
| Haiku 4.5 | $0.00160 | $0.00160 |
Grade A, and why
gopher-ai AGENTS.md scanned grade A with 1 finding 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 1mo 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
For Codex, "global" means installing plugins through the Codex marketplace cache so they load in every Codex session, regardless of the working directory. This is what `install-all.sh` uses for the curl one-liner. How it starts
The opening of the file, as written. The whole thing — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project Overview
gopher-ai is a Go-focused development toolkit distributed as both Claude Code plugins and Codex plugins. Each plugin bundles related skills that activate automatically or can be invoked explicitly.
The Codex plugin set currently includes go-workflow, go-dev, gopher-guides, llm-tools, go-web, and tailwind. The repo's productivity module is currently Claude-only.

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.
