agent-model

agent-model is an agent for coding agents from pdugan20/claudelint. It costs 11 tokens per session (472 once invoked), scanned A, original, MIT.

A format check for an agent's selected Claude model. It accepts known aliases such as `sonnet`, `opus`, `haiku`, and `inherit`, or a full Claude model ID.

In plain words
What is it for?
Use it when choosing which Claude model an agent should use. The `inherit` value makes the agent follow the model selected by the parent conversation.
Why use it?
It warns about model values that may be misspelled, use the wrong naming style, or refer to another model family.

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

agent-model 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 3d 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.

What it actually says

agent-model

Rule Details

This rule checks that the model field in agent markdown frontmatter is either a known alias (sonnet, opus, haiku, inherit) or a full Claude model ID (e.g. claude-opus-4-6). The inherit option tells the agent to use the parent conversation model. Unrecognized values produce a warning since Claude Code accepts arbitrary model strings.

How To Fix

Set the model field to a known alias (sonnet, opus, haiku, inherit) or a full Claude model ID (e.g. claude-opus-4-6).

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.
