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 | $0.00655 | $0.00655 |
| Opus 5 | $0.00328 | $0.00328 |
| Sonnet 5 | $0.00131 | $0.00131 |
| Haiku 4.5 | $0.00065 | $0.00065 |
Grade A, and why
anti-sycophant-ai-agent-skills 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 13d 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.
How it starts
The opening of the file, as written. The whole thing — 41 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
This file is for AI coding agents (Claude Code, Cursor, Copilot, Gemini, OpenCode, Codex, Aider, Cline, anything else) working inside this repository. For end-user installation of these skills in your own projects, see docs/getting-started.md.
What this repo is
A pack of three skills that get AI assistants to push back on unvalidated product ideas instead of agreeing by default. The skills are plain Markdown with YAML frontmatter — portable across any LLM that accepts a system prompt.
Repo layout
skills/ One directory per skill, each containing SKILL.md.
prove-the-premise/ Pressure-test idea premise before building.
hobby-or-business/ Separate project enthusiasm from business reality.
one-real-conversation/ Reject validation theater; demand one honest human conversation.
.claude/commands/ Claude Code slash commands.
.gemini/commands/ Gemini CLI slash commands.
.claude-plugin/ Claude Code plugin manifests.
docs/ Per-tool setup guides.
Rules for agents editing this repo
- Skills live at
skills/<name>/SKILL.md. Kebab-case directory name. The directory name must match thename:field in the frontmatter exactly. - Frontmatter is non-negotiable. Every skill needs
nameanddescription. The description must include bothUse whentriggers and aDo NOT use whenoff-switch. Skills without an off-switch are bugs. - One file per skill:
SKILL.md, and nothing else inside the directory. Noscripts/, no supporting.mdfiles, no references. If a skill outgrows ~500 lines, that's a sign the skill is trying to do too much — split it into two skills with distinct triggers, don't add scratch files. Long shared reference material across multiple skills would go in a top-levelreferences/directory; so far nothing has needed one. - Don't add tooling without being asked — no test runners, validation scripts, CI configs, or hooks. The repo is intentionally minimal.
- Preserve tone. The skills are blunt on purpose. Don't soften them. But also don't sharpen them into cruelty — that's a tone regression.
- Cross-reference rather than duplicate. If one skill needs guidance from another, link to it by name.
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.
