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 | $0.00497 | $0.00497 |
| Opus 5 | $0.00249 | $0.00249 |
| Sonnet 5 | $0.00099 | $0.00099 |
| Haiku 4.5 | $0.00050 | $0.00050 |
Grade A, and why
anti-sycophant-ai-agent-skills CLAUDE.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 12d 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 — 33 lines — stays where its author put it; the contents beside it link to each section on GitHub.
anti-sycophant
This repo is a pack of skills designed to get AI assistants — including Claude — to stop agreeing with bad product ideas by default. The skills install as a Claude Code plugin, but the underlying SKILL.md files are portable Markdown and work with any LLM.
What's in here
skills/
prove-the-premise/ SKILL.md Pressure-test an idea's premise before any build.
hobby-or-business/ SKILL.md Separate project enthusiasm from business reality.
one-real-conversation/ SKILL.md Reject validation theater; demand one honest human conversation.
.claude/commands/ Two slash commands: /validate-idea, /reality-check
.gemini/commands/ Same two, as Gemini CLI TOML
docs/ Per-tool setup guides (Claude Code, Claude.ai, Cursor, Gemini, Codex, others)
.claude-plugin/ Claude Code plugin + marketplace manifests
Conventions
- One skill per directory:
skills/<kebab-case-name>/SKILL.md. The directory name must match thename:frontmatter field exactly. - Every skill has YAML frontmatter with
nameanddescription. The description must include both what the skill does and explicitUse when/Do NOT use whenclauses — the model decides whether to load the skill purely from the description. - Every skill has an off-switch. A skill without one becomes a nag and gets ignored.
- Skills are short by default in the output they produce, even when the skill body itself is long. "Lead with the verdict, two or three points, offer to expand" is the response shape.
When working in this repo
- New skills go in
skills/<name>/SKILL.mdonly. Noscripts/directory unless the skill actually ships a runnable helper. - Don't add hooks, validation pipelines, or test infrastructure unless asked. The repo is intentionally minimal.
- Don't soften the tone of existing skills. Bluntness is the point. But never cruelty — that's a tone bug, not toughness.
- Cross-reference skills by name rather than duplicating content (e.g. "see
one-real-conversationfor validation theater"). - See
docs/skill-anatomy.mdfor the full format spec andCONTRIBUTING.mdfor the quality bar.
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.
