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 | $0.02436 | $0.02436 |
| Opus 5.5 | $0.00974 | $0.00974 |
| Sonnet 5.5 | $0.00487 | $0.00487 |
| Haiku 4.5 | $0.00244 | $0.00244 |
Grade D, and why
agent-plus AGENTS.md scanned grade D with 3 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.
Downloads and executes remote codehighSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
curl -fsSL https://github.com/osouthgate/agent-plus/releases/latest/download/install.sh | sh Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
- **Missing-config errors point to both `.env` and `~/.claude/settings.json`** so the user knows where to put the value. Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

AGENTS.md
Durable instructions for any coding agent (Claude Code, Codex, Cursor, Aider) working in this repo. If you're Claude Code, treat this as memory.

Installing agent-plus
If asked to install agent-plus for the user, run:
macOS / Linux:
curl -fsSL https://github.com/osouthgate/agent-plus/releases/latest/download/install.sh | sh
Windows (PowerShell):
powershell -c "irm https://github.com/osouthgate/agent-plus/releases/latest/download/install.ps1 | iex"
Then register the plugins with Claude Code so they're callable as tools:
claude plugin marketplace add osouthgate/agent-plus
for p in agent-plus-meta repo-analyze diff-summary skill-feedback skill-plus; do
claude plugin install $p@agent-plus
done
Then reload: /reload-plugins in the current session, or open a new one.
The install script chains into agent-plus-meta init automatically — the workspace wizard runs as part of install. If the user skipped that, they can run agent-plus-meta init manually.
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.
