What is lmagent AGENTS.md?

A Spanish-language instruction file that defines how the lmagent v4 engineering agent should operate. It sets expectations for software quality, security, initiative, visual work, and maintaining a task file.

Use it to guide lmagent v4 sessions, including analysis, planning, implementation, security checks, and updates to task.md.

It gives the agent a central set of project rules and a prescribed execution process to follow during software work.

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.

Model	Per session	Once invoked
Fable 5.1	$0.07555	$0.07555
Opus 5.5	$0.03022	$0.03022
Sonnet 5.5	$0.01511	$0.01511
Haiku 4.5	$0.00756	$0.00756

Security

Grade A, and why

lmagent 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 2mo 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.

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.
