What is skillmaxxing AGENTS.md?

A set of instructions for maintaining the Skillmaxxing agent-skills repository and its files for several coding assistants.

Use it when designing agent behavior, choosing modes, routing tasks, or updating the Skillmaxxing repository and its adapters.

It helps keep shared instructions and their copies aligned, so different assistants follow the same rules.

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	$0.00169	$0.00169
Opus 5.5	$0.00068	$0.00068
Sonnet 5.5	$0.00034	$0.00034
Haiku 4.5	$0.00017	$0.00017

Security

Grade A, and why

skillmaxxing 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.

What it actually says

Agent Skills System Repo

CRITICAL: When a task is about agent design, routing, skills, mode selection, or maintaining this repo, read agent-skills-system/SKILL.md immediately and treat it as the source of truth.

Adapter Rules

Keep one active mode per phase
Do not duplicate the full system in this file
This file is the shared adapter for Codex, OpenCode, Cursor, and Windsurf
Keep README.md, CLAUDE.md, GEMINI.md, .continue/rules/agent-skills-system.md, .agents/skills/agent-skills-system/SKILL.md, and agent-skills-system/agents/openai.yaml aligned with the canonical skill
If an adapter and the canonical skill disagree, the canonical skill wins

Changes

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.
