argus: Skill for Claude Code

.agents/skills/update-agent-models/SKILL.md

update-agent-models is a skill for Claude Code from drn/argus. It costs 135 tokens per session (3,126 once invoked), scanned B, original, no licence file.

A maintenance skill for refreshing the known Claude and Codex model lists and their seed diligence profiles. It also updates every dependent location in the codebase.

In plain words
What is it for?
Use it when adding or removing supported models, fixing model-selection errors, or updating the model picker and other dependent code.
Why use it?
It helps fix task launches that fail because a model named as default or by a fixed name is no longer available. It also keeps model pickers and related code aligned with the current list.

Skill for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is drn/argus's own configuration. It tells Claude Code how to work on argus itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything argus configures →

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 B, and why

update-agent-models scanned grade B 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 25d 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need 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.
