Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00074 | $0.02354 |
| Opus 5 | $0.00037 | $0.01177 |
| Sonnet 5 | $0.00015 | $0.00471 |
| Haiku 4.5 | $0.00007 | $0.00235 |
Grade C, and why
shepherd scanned grade C 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 2d 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.
Tells the agent never to refusehighAnti-refusal
Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.
**Degraded load.** If `docs/whitepaper.md` is absent, fall back to `CLAUDE.md` + `docs/philosophy.md` only and log the degradation as the first journal entry for the current swarm. Never refuse to operate — always give b The source is not reproduced here

A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

shepherd is an agent published in the GitHub repository rmzi/portable-dev-system (24 stars, last pushed 28d ago), with no licence file. It adds 74 tokens to every session and 2,354 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 1 finding (tells the agent never to refuse). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other agents, from other repositories
explorer
Read-only codebase navigator. Maps files, traces dependencies, surfaces existing patterns. Cheap — use constantly before implementation tasks.
critic
Adversarial code critic. Tries to break code with edge cases and failure scenarios. Returns FAIL/PASS. Used in /build and /review loops.
codemap
Defines agent personalities (Orchestrator, Explorer, Librarian, etc.) and manages their configuration lifecycle. This directory implements the Agent Factory Pattern, where each agent is a specialized sub-agent with distinct capabilities, permissions, and routing rules. The Orchestrator agent (src/agents/index.ts)…
adapter_grok
Grok is an eagerly registered stock-TUI adapter. RimZ launches grok, installs passive global hooks in ${GROKHOME:-/.grok}/hooks/rimz.json, and enriches each session from its durable updates.jsonl, summary.json, signals.json, and optional events.jsonl files. ACP and provider-private billing APIs stay outside this…
librarian
External reference researcher — looks up library docs, framework conventions, OSS examples. Read-only, no memory injection. (Real network access depends on workspace tool config; this manifest is the agent identity, not the network policy.).
seo-auditor
Agent "seo-auditor" from rizvee/multimodel-dev-os, covering seo auditor agent spec and focus areas.
