Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

awesome-herdr 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 9d 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.

The opening of the file, as written. The whole thing — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Working rules and language guidelines for anyone — human or agent — editing this repository. It is a curated, plain-English index of the Herdr ecosystem. Keep it lean, minimalist, and immediately useful.


1. Project Philosophy & Minimalist Structure

  • No Onboarding Tutorials: Do not add introductory installation essays, "how to choose your layer" tables, or getting-started walkthroughs to the catalog root. Keep the README strictly minimalist: title, official links, Table of Contents with counts, and direct jump links into the tables.
  • Fast Jump Navigation: Readers should jump straight to the relevant problem domain from the Table of Contents in 1 click.

2. Project Language & Voice Values

The language of this catalog must be simple, direct, and developer-friendly:

2.1. Plain-English, Verb-First Prose

  • Lead with active verbs (Adds, Teaches, Runs, Maps, Monitors, Filters, Connects, Orchestrates, Embeds, Extends, Dispatches).
  • Avoid passive constructions, convoluted em-dash chains, and marketing buzzwords ("ultimate", "blazing fast", "revolutionary").
  • State clearly what a Herdr user can do with the tool, not a laundry list of generic features.

2.2. The 1–2 Sentence Rule

Every project entry must be strictly 1 or 2 concise sentences:

  • Sentence 1: What the tool specifically does for a Herdr user.
  • Sentence 2 (optional): Key capabilities, supported models/agents (Claude, Pi, Codex, OpenCode), or notable workflows.

2.3. Subcategory Header & Table Standards

Every subcategory begins with a count and a 1-sentence summary, followed by a clean 2-column markdown table:

### Multi-agent fleets and supervisors

*20 projects. Higher-level systems that coordinate several agents, roles, tasks, or repositories.*

| Project | What it does |
|---|---|
| [**owner/repo**](https://github.com/owner/repo) | Plain-English explanation of what the tool does and who it is for. |

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.
