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 | $0.00621 | $0.00621 |
| Opus 5.5 | $0.00248 | $0.00248 |
| Sonnet 5.5 | $0.00124 | $0.00124 |
| Haiku 4.5 | $0.00062 | $0.00062 |
Grade A, and why
agent-toolkit AGENTS.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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 45 lines — stays where its author put it; the contents beside it link to each section on GitHub.
REQUIRED: Read README.md before doing anything else. It documents the project's purpose, setup, and commands.
Project Overview
This is a personal toolkit for working with AI agents like Claude Code. The project uses Bun as the runtime and package manager. It contains skills following the Agent Skills specification and reusable documentation for agent workflows.
Commands
bun check-types: Run TypeScript type checking.bun prettier --write <path>: Format a file.
Architecture
Project Structure
This is a monorepo. Each plugin lives under plugins/ as its own subdirectory. To see all plugins and their descriptions, read .claude-plugin/marketplace.json.
- TypeScript Config:
tsconfig.jsonat root validates the entire project - Plugins: Individual plugins under
plugins/, each with a.claude-plugin/plugin.json,skills/, and optionallycommands/
When asked to edit a skill in this repository, always edit the skill under plugins/<plugin-name>/skills/ here—not an installed copy in an agent's own plugin or skills directory.
Interactive Command Workflow
Some skills need to hand control to the user in a separate window and block until they're done, such as opening Neovim to edit a file. That building block lives in plugins/ls-interactivity: ls-interactivity:interactive-command opens the given command in a new herdr tab and waits for it to close, and ls-interactivity:interactive-edit builds on it. ls-interactivity:interactive-review instead opens Hunk and returns immediately; decisions arrive through hunk verdict listen, from the hunk-verdict extension.
Not every prompt needs a fully executable window. plugins/ls-interactivity/skills/interactive-ui hosts small, themed TUI utilities for quick user interactions without having to write a full application.
These utilities are located in plugins/ls-interactivity/skills/interactive-ui/scripts and come in two types:
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.

agent-toolkit AGENTS.md is an instructions file published in the GitHub repository LandonSchropp/agent-toolkit (3 stars, last pushed today), licensed MIT. It adds 621 tokens to every session, about $0.0025 per session on Opus 5.5. 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.
