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 | $0.00354 | $0.00354 |
| Opus 5.5 | $0.00142 | $0.00142 |
| Sonnet 5.5 | $0.00071 | $0.00071 |
| Haiku 4.5 | $0.00035 | $0.00035 |
Grade A, and why
fable-workflow-skill 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 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
fable-workflow-skill
A single portable agent skill (SKILL.md) that ports a Fable-style working method onto any
model. This repo is docs + one skill — there is no build step.
Layout
SKILL.md— the skill itself (the only file agents load). Keep it under ~120 lines.prompts.md— copy-paste prompt templates referenced by the skill.integrations/— adapters for other tools:AGENTS.md(Antigravity/Codex/Aider/Zed/…) andcursor/fable-workflow.mdc.benchmark/RESULTS.md— the cross-model A/B evaluation.README.md/README.ko.md— English + Korean. Keep both in sync when editing.install.sh— copiesSKILL.md+prompts.mdinto a target.claude/skillsdir.assets/banner.png— repo banner (user-supplied).
Editing rules
- Edit the skill in
SKILL.mdin place; don't split it into more files. SKILL.mdis canonical;integrations/AGENTS.mdandintegrations/cursor/fable-workflow.mdccarry a condensed copy — keep all three in sync when the method changes.- Any change to one README must be mirrored in the other language.
- Benchmark numbers are from a small pilot — if you rerun, update the caveats too, don't just swap the table.
Adding a README language
Add README.<lang>.md and update the language switcher line at the top of every README.
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.
